How to make a refrigerator with your own hands. Step-by-step instruction
Going on a trip for several days or on a trip by car, the question of the safety of products often arises.
And modern offices are not always equipped with refrigerators, so it becomes problematic to refresh during the day or just keep lunch.
Therefore, we decided to tell how to make a refrigerator yourself and close the issue of storage of products.
How to make a refrigerator with your own hands
The article will talk about refrigerators made on the basis of the Peltier element, which has the following advantages: there are no mobile parts, does not contain gas or liquid, does not make noise. Perhaps the only minus will be its high cost.
First of all, you need to understand the principle of operation of such a device. Ordinary work on the refrigerator Freon, for a mini refrigerator it will not work. The principle of work of figuratives is completely different. The essence of the device is as follows: when connected to the network through the semiconductors, the material on one side of the plate is cooled, and heats up on the other. Such work is ensured due to the insulating laying between the heated and cooled surfaces of the element. If you additionally remove heat from the hot side of the plate, then the temperature on the cold will drop even lower. This is exactly what we need for a portable refrigerator.
Answer to the post “Mongolian eco. refrigerator »
They froze water in a bucket, after a few hours a small hole was made on top, the water was spilled with an uncleaned water, and a hole was made from below with a knife. On the street they put a tin cover from the jar on the snow, a small candle on it, they put on this product on it. A hole on top. For air. It burns 3-4 hours. He is not afraid of wind. I have never seen anywhere, that someone except us did this. On the Internet I took the idea. They say that in the Scandinavian countries to exhibit such and ordinary lanterns on the street in winter tradition. If you have a similar experience, show.
Replacing the refrigerator compressor
The engine thundered on the old refrigerator. Cold, but weak, and volume is like three at the same time. Well, I decided to replace it with a more modern compressor. He is on R134A, therefore Freon will pump the appropriate, but the old Freon was pumped into the cylinder and skimmed the system. About a hundred grams of Freon did not release into the atmosphere, but retained, maybe I will still in the air conditioner. There you also need to change the compressor.
While pumping out and vacuuming, I prepared the necessary tools, devices and consumables. And there are not few tools, a pipeline, burner, propane, oxygen, ticks and pliers, scales, manometers with hoses, local light, an electric extension cord, vacuum pump, a copper.fraud
Sweeps easily and simple, for a long time the preparatory process lasts, while you collect everything and prepare everything, and solder both joints for a couple of minutes, then again it takes off, at least 10-20 minutes. And that’s all, you can weigh a cylinder with a refrigerant, connect and fill a freon, I have 145 grams on my passport. The new compressor works approximately at the level of the noise of Freon gurgling inside the refrigerator. That is very quiet.
PS: The repair is not so complicated as restoring order after it, after all, you need to lay out all the tools in their places. Motors, compressors and cylinders are returned to the place, wash the hoses, put the refrigerator in place and pouring it to load it with products.
The vacuum pump is quite satisfied, solder a couple of fittings to the compressor from the refrigerator, it can not only create pressure, but also vacuum
The compressor used two cubic meters of volume from the refrigerator. I just see no sense in buying standard for 3500, this compressor is twice as expensive, but it is free))
Burner of the fifties of release, but quite functional
I have oxygen stored in cylinders from scuba gear, not as severe as standard for 70 kg. But also the weight is not small, 22 kilograms along with the burner and hoses.
I solder where it is convenient for me, I didn’t even fall off the old joints.
It suddenly turned out that the cans of kilograms with Freon were exceeded for 1200, like recently took 800 for 800.
Useful acquisition. cold battery
Cold battery: properties and application
It is very convenient and effective to use the cold battery in dachas, in marching conditions. They perfectly preserve the cold in the bags of refrigerators as a cooling component. Manufacturers advise using 1 standard battery for 15 liters of coolant volume, but it is better to use 2-3 containers to effectively preserve the cold.
And in home stationary conditions, you can successfully use the battery for energy saving, placing it in the freezer and thereby maintaining a stable temperature in it, and even increasing the freezing power. Batteries will serve in the case of hygienic defront of the refrigerator.
For problems with electricity, the battery will help save the products until the unfortunate with electricity is not eliminated until.
Industrial cold accumulators are used in the sale of ice cream products and when transporting products with perishable properties.
Preparation and action
The time of the beneficial action of the battery depends on several factors:
Depending on the volume of the bag, several batteries may be needed. It is very important to correctly place them in the space of the bag:
As the composition is defrosted in the battery container, it is pulled out of the bag, washed with water, wiped dry and placed again in the freezer.
Store the cold battery, while it is not used, it is necessary in the refrigerator, this ensures the safety of the battery and increases the period of activity of the refrigeration-modricular device.
Types of cold batteries
The design features of the cold accumulators depend on its purpose. Most often they are rectangular and flat, which ensures good contact and fit. The shell is made of a hard strong polymer, which does not change its shape or from a dense plastic film, which makes it possible to give the battery the desired shape before freezing.
Manufacturers are most often engaged in the manufacture of three main types of cold accumulators, depending on the filler:
The choice of a suitable battery
When choosing a cold battery, it is important to consider that a characteristic blue color does not have any functional properties: this action has a dye.
Магниты сувениры своими руками. Несколько вариантов.Refrigerator magnets with your own hands.
The term of use of batteries made by industrialized is unlimited.
Manufacturers guarantee the environmental friendliness and safety of materials that do not change their characteristics depending on the time and sharp temperature fluctuations. Typically, the capacity of the standard battery 250-800 ml.
When choosing a battery for your needs, take into account its parameters: volume, design, composition of filler.
Given the above, we offer several recipes for making liquid for a homemade cold accumulator.
- in a liter of ordinary drinking water, it is better to prepare a saturated solution of table salt, adding about 400 grams of sodium chloride (table salt) to it;
- Add three liters of water to the composition and add the required amount of wallpaper glue. The consistency of the fluid should be gelo.like;
- Pour the solution into plastic containers with a screw cover or into plastic bottles;
- put in the freezer and freeze.

Such a battery can maintain the temperature in a special bag for a long time.20 degrees with.
Such a battery composition is able to maintain the temperature of the cold before.10 degrees with.
This is the easiest, you can say a force majeure way to make a cold battery. It is necessary to mix water and wallpaper glue in proportions: 96 grams4 grams.
Minus 1 degree Celsius in a bag of products can create the conditions of the refrigerator, and will hold out for some time.
At home, it is difficult to preserve the requirements of tightness, so special attention when using home.made cold accumulators must be paid to safety, especially if they are planned to be used to cool food.
Types of cold batteries and properties
The most significant element of the cold drive is the contents. the preservation of the initial characteristics and the duration of the period in which it can be eaten without the risk of poisoning is possible on the properties of the “filler”. Stores offer several types of cold accumulators, which differ in capacity. from 250 ml to 0.8 liters. The drives also differ in terms of purpose:
During the production of such drives, exclusively safe and non.toxic polymer compositions are used.
Using the film surface allows you to adjust the shape of not hardened sources. Temperature fluctuations, thanks to certain materials, are passed to the cold accumulators without a trace.
Drives are a sealed plastic container, inside of which a certain substance. A liquid acting as a refrigerant can be represented by the following compositions:
- Gel. the outer part is made of film, filling. the same composition with significant thermal conductivity indicators. Supports the initial indicators of the temperature of products. The gel is also able to create areas of low temperature. when preliminary in the freezer for several hours. Carboxymethyl cellulose, which is the basis of the gel in the accumulators of the cold, in case of contact with medicines and food, does not become causal for their damage.
- Salted water. maintains the temperature in the area from.20 to 8 ̊s. But, no more than 1 day is enough charge of such a battery. The outer part of the drive is made of solid plastic, inside which a salt solution is poured.
- Silicon.containing mixture. the drive is made of durable material, and polymers with silicon crystals are included in the refrigerant. Such a battery for a refrigerator bag maintains a temperature within 0 2 ̊s. The drive is not exhausted for a long time. up to 160 hours.
When a long trip is planned or a trip and it is necessary to transport perishable products or medicines that need certain storage conditions, they recommend choosing cold sources of a larger capacity. for reliability. If this is not possible, they take several batteries that are located in 1 bag.
Using cold drives
The principle of operation of drives for all varieties is the same. Before using a portable compact cold generator, a person needs to charge it.
To do this, put the device in the freezer for 8 hours. until the refrigerant inside the sealed container freezes. In the case of refrigerators with the knofrost system, placement of the battery does not matter.
When ice intends in the freezer, it is advisable to have a drive closer to it.
Recommended in a period when there is no need for the drive, store it in the freezer. Lack of temperature jumps allows you to increase the operational period of the device.
The long.term presence of the battery in the freezer does not affect the characteristics of the device. minus temperatures do not dislike the refrigerant or hermetic housing. After the element spent the charge, the drive is thoroughly washed, allow the body to dry independently and then again sent to the freezer.
It is necessary to clean the drive after each use, since the condensation that occurs during the use of the battery leads to contaminants on the surface of the hermetic capacity. The material is able to import various smells of food and medication. If the case has already absorbed smells, it is virtually impossible to remove them. there is a risk of damaging tightness.
Most often, one cold battery is enough for a refrigerator bag, which is placed on top of products or medicines. But sometimes it is advisable to lay several drives. When using several elements, they are placed not only on products, but also between and under them. This need arises in the following situations:
- frequent opening of a portable refrigerator;
- significant volume of products/medicines;
- sudden disconnection of electricity;
- The long duration of the trip.
The battery charge rate depends on the possibilities of the home refrigerator. The standard household freezer maintains the temperature inside.18 ̊s. In this case, you need about 12 hours to charge. At temperatures from.23 ̊s, the charging period is standard and equal to 8 hours. The number of freezing cycles of factory cold drives is not limited.
How to choose a device
Cold drives differ in constructive features, the type of refrigerant and its volume in a sealed container. These parameters must be taken into account when choosing a refrigerator. The color of the refrigerant does not affect the characteristics of the battery and does not carry a functional load if another is not indicated by the manufacturer on the package.
Some factory cold batteries are permissible not only to freeze, but also to heat. A substance inside the container can maintain products with warm. Когда необходимо использовать аккумулятор холода в варианте обогревателя, его заряжают в микроволновке. Heating time should not exceed the specified by the manufacturer.

Heating in a microwave oven is possible only in the case of purchased drives, the manufacturer of which allows their use with heating.
DIY cold drive
When considering only cooling options, then these devices can be made with your own hands. A plastic bottle is the simplest homemade-it is filled with clean water and laid in the freezer for 2-3 hours. There is enough such a battery to bring the products to the cottage, but the efficiency can be increased by changing the filler (refrigerant).
How to make a mini refrigerator 12 in your own hands
A small, low.voltage refrigerator will become a stunned assistant on hot summer days. It can be used in a manifest, put on a table at work. This mini will retain products for you and cool drinks at high speed.
It is easy to assemble such a refrigerator yourself, a few hours will be enough. All details and parts can be bought in any city in the construction and computer departments, or order via the Internet.
The following will need:

To make the refrigerator more realistic, not just a box with straight angles, but a housing with semicircles glues. To do this, cut the sheets along the radius.
Glue the bottom of the refrigerator. In the upper part, drill holes for better cooling.
In the diameter of the large cooler, we cut out a circle from the porous PVC substrate.
In the center of it, we make a neckline for the element peltier. Install it, fix it on the sides of glue. Lubricate the sides of thermal conductive paste. We apply a rectangle of aluminum and fasten it to a large radiator.
Next, on the other hand, fasten a small radiator.
We take the wires to the upper part. We seal all the cracks with hot glue.
Install this cooling element in the upper part of the refrigerator body.
We connect all coolers and fans parallel to each other, then to the power connector through the button.
Cut the walls of the refrigerator from thin foam.
We close the upper part with a strip with a built.in thermometer.
Cut the refrigerator door from the plexiglass. Glue the loop to her.
We connect the refrigerator to the power source.
Put a couple of drinks and other goodies inside.
After 40 minutes, the temperature inside the chamber dropped to 5 degrees Celsius. Thanks to the use of active cooling in the form of fans, this time is an excellent result.
The work of a mini refrigerator
And finally, the result of the work is such that in thirty minutes the temperature inside the camera fell from 42 to 16 degrees Celsius. Drinks cooled to a temperature of 20 degrees Celsius. And all this in 30 minutes!
Of course, the efficiency of such a refrigerator is much lower than that of the compressor, but it has its advantages, one of which is low.voltage nutrition, which can be not only 12 in! Naturally, it is quite possible to feed it from the USB port of the computer, though the return will be lower than when power from voltage 12 V.The total power consumption during power from the 220 V network is about 100 W.
How to make a refrigerator with your own hands
The choice, frankly, is small when the question arises of how to make a refrigerator with your own hands. Today, frost is produced by two methods. The use of four states of freon or electrical elements dumplings.
It is important to save the cold. A sealed compartment will be required, the correct heat.insulation measures that prevent exchange with the environment. Consider the methods, get ready: a simple path will not turn out.
Let’s think together, what can you make a refrigerator from.
The principle of frost production by refrigerator
Before making a refrigerator yourself, survey existing structures. We offer a brief thematic excursion below. We apologize, for the lack of adsorption models, they also work on the freon. There are hardly capable of getting the necessary materials, substances, contributing to the implementation of the concept.
First, know: 99% of household refrigerators operate Freon. Devices on Peltier elements can be found as automobile freezers. The electric current flows through the joint of two heterogeneous semiconductors, the result is formed by cooling of one material.
Another, on the contrary, heats up. The external radiator of the refrigerator on the elements Dagger requires intense cooling. It is achieved by the choice of a large size of the cut aluminum part, or the introduction of a fan, forced blowing.
We see the idea inside modern system blocks of personal computers.
Who wants to make the refrigerator on their own can start with this. Find the Peltier element for cooling the processor, better than two or three. Actually, the detail is very curious.
In the heat easily brings the processor temperature to minus 10 degrees Celsius. Therefore, a homemade device is suitable as a cooler. The problem is limited by a small volume. Think! The power of a typical processor is 80. 100 watts. Half is released with heat. Therefore, the element of the processor cooling dumplings element (less than 100 watts) is not so buried.
We’ll make a reservation right away: the freezing power (cold production) and the rosette consumed are different things. The efficiency of the efficiency reaches 200 percent. Concerns most samples of climatic technology:
The ability of the elements of Peltier are certainly unknown. Cold production is not given. Peltier elements are designed for fixed capacities, the manufacturer offers to trust.
The problem is one: the speed of the processor temperature drop cannot be judged by the parameter, too many unknown. Found on the website http: // forum.Sirius.DN.UA/ Figure, which depends on the cold production of the element peltier Frost-72. Linear graph, makes it possible to calculate the necessary parameters to create a refrigerator with your own hands.
Dependence of the cold production of the Peltier element
With an increase in the supply voltage to 16 V (maximum permissible) cold production grows in parallel. You can improve the result a little. Let’s think about the performance of the Stinol 102 refrigerator:
How to make bioceramic fridge magnets with your own hands (salt dough). Hand made product.
Do not rush to fold, make it in accordance with the numbers 75-100 and 100-120, cold production depends on the temperature. But what is ΔT. the temperature difference between the plates.
We will better remove heat from the hot side, the Peltier element will work more efficiently. Lowen to take measures, the temperature difference will reach 68 degrees Celsius (nutrition 12 volts), cooling will stop.
Therefore, in advance are powerless to predict. Suppose the room temperature is 22 degrees Celsius, the refrigerator. plus 5 degrees Celsius, with perfect cooling, a power of 38 W is obtained.
Easy to see: for Stinol 102 you will need at least two or three frost 72.
As for the freezer, power cannot be realized with conceivable losses.
The article of this site explains: the peak efficiency of the device is 62% (ideal case), the creation of a homemade refrigerator in terms of electricity saving cannot be called a good venture. The need for a freon is disappeared, the system is silent.
Those who want to build a freezer will provide a brief calculation. The temperature difference will be 22-(-18) = 40 degrees, power is 20 watts. Buy 6 Frost 72 elements. Let’s see in monetary terms.
According to the site http: // www.Chipdip.ru/, one element Peltier Frost 72 costs 1500. Do I need a freezer for 9,000 (subtracting the cost of the material of the box), decide for yourself. The thermostat will be needed. Plus device: capable of working on heating. Just change the polarity of the power. A homemade refrigerator will become air conditioning, you can warm food inside. For the thawing mode perfectly. By the way, the fact needs to be clarified. We turn Dumpete’s effect. Skipping current in the opposite direction, we reach heating. The principle of operation of the refrigerator is limited by the effect of lowering the temperature of one side of the dumplings element, we turn the effect.
Let’s make the refrigerator case
Avoid the use of polyurethane foam: you will need overalls. Buy a core of insulation (mounting foam). The need to look for a respirator will disappear. Polyurethane foam expands, gains volume relatively slowly. Air than the material. better isolation.
For insulation, polyurethane foam will need to make a box with double walls, a similar door (cover). Difficult task, since you need to fill the bottom with the insulator.
Decide for yourself what is best to do, we recommend that you leave the technological holes in complex accessories. After hardening the polyurethane foam, cut off the excess, patch up unnecessary holes. The problem of insulation is being solved.
Avoid the contact of the polymer with products.
Poliuretan foam covers the gaps of entering the elements of Peltier into the camera. Ideal isolation that is difficult to achieve in a different way. Peltier elements are expensive. The refrigerator should be less, isolation. better.
DIY refrigerator in the car (3 options, photos, step)
DIY refrigerator in the car (3 options, photos, step)
With my own hands, passive autothermos I know if I chose the section correctly, but I decided that here this topic will be in place. I suggest everyone to share Home Made with my experience I myself want to share with teammates the experience of building a homemade, mobile-comrade refrigerator.
The thing is very necessary, for trips to nature and to the sea, of course.This year we will definitely go to the sea. “Brakes” and drinks, so as not to deteriorate, it is better to keep in the cold. And for this you need a refrigerator. Buy a cigarette lighter from a cigarette lighter for 4500 r. The “toad” does not give me.
Therefore, even for the old car, it was decided to make a new, capital refrigerator with “cold batteries” in the form of frozen one and a half with water. The old refrigerator made of packaging cardboard served 3 trips to the south, and was ruthlessly thrown into the garbage dump (attached a photo below (not a garbage dump and a refrigerator)).
So what and how was done. The size of the refrigerator was chosen 400400300 mm, based on the size of the trunk in the previous car (it would take up a lot of space too much, and there would be nowhere to lay things). Insulate, or rather heat.insulated, I decided to foamed insulation with foil on one side, 10 mm thick.
Width 1.2 m, length 1 m. Price for today 90 r/1m.
The material of the case was the waste of our furniture production. a wood.fiber slab (or, if clearer, wood.fiber plate) 10 mm thick. Bought 2 aluminum corners of 1515 mm for 120 r. For both. Also bought by exhaust rivets 416 (100 pcs 50 p.) and 2 furniture bar loops of 30 r. Each. That’s all expenses. 295 r. Tools and equipment are borrowed at work (where the refrigerator was assembled).Cutting off the corners, slowly, we begin to collect the box of the future refrigerator. As a result of the “titanic” works, such a pretty box turned out.On the lid of the box, I put a clicking lock and folding handle from wire. So that the finished refrigerator with packed food can be transferred in the hand. Otherwise he, stuffed with water and food, becomes very heavy! But, as they say, his own burden does not pull Now we start pasting the box from the inside with a heater. I decided that the bottom and cover would be pasted into 2 layers of insulation, and the walls in 1 layer. For gluing I used “liquid nails”. Having smeared the harvesting of the insulation with “nails”, he glued it to the wall and pressed it with a load. It was glued well, then tried to tear it off. the glued seal did not succumb.As a result, after 3 days of work in free time from the main work (which there is not so much), it turned out such a pretty refrigerator with a folding upper lid on the latch.In the corners or to the bottom, 4 one and a half liter bottles of water, or 6-8 half-liter, previously frozen in the freezer, will be fixed or laid. You can use mineral water, cold, and with gas, in the heat uh as invigorates. It is better to take a half.liter mineral water, this volume is the most practical. The bottles are not full of water, otherwise when the water freezes, the ice will expand and tear the bottle, and the products will swim in thawed water. To save space in the refrigerator, you can buy in the store a corporate “cold battery”-these are special bags or flat boxes with liquid inside, which are used instead of bottles (one large costs about 120-150r.). Only bottles with spring water are free! And even when the water begins to melt in them (and this is somewhere in a day), it can be used for cold washing or drinking. Using the previous, cardboard refrigerator, food and drinks not eaten and not drunk along the road, they reached the sea with cold. In the new refrigerator at sea, we even brought our ice, it did not completely melt! This refrigerator can be used as a stool. I did not specifically paint, so that it was visible if something happens from the wood-fiber plate (for example, if it starts to warmer from the water). The refrigerator is completely satisfied, he justified the time and the little money spent on its manufacture. And there is a lot of benefits from him.
DIY passive autothermos
I’ll say right away. that this thermos auto.chronicle was invented by my friend Valera!! For which we are very grateful to him. Lives in the south, it is hot with us, so there are catastrophically not enough auto.chroniclers for products on vacation, especially if we leave a large company.
Valera made such a thermos-hub with his own hands a few years ago, so he decided to do this.
Total, having bought a box for children’s toys. 350, 2 sheets of foam 2×50 = 100, 2 two skeins of metallized tape 2×100200, universal glue 80, installation 120 total 850 and 2.5 hours of my precious time. Go:
- After two days, compotes from a thermos on the Dolzhanskaya spit. Over the side of about 40 degrees, the flight is normal:
- Active refrigerator on an element DIRTHER with your own hands
- Prelude: somehow boring in the evening, gently stacked computer jewelry from one place to another.
1) Peltier element (rarely used to cool computer processors) http: // www.ebay.com.AU/Sch/Industrial-/170769/I.HTML?_nkw = peltier_catref = 1_fln = 1_trksid = p3286.C0.M282HTTP: // ru.Wikipedia.org/wiki/element_pelier 2) old boxing 3) pair of radiators from computers 3) wire and horseradish in a cigarette lighter.
By the will of fate, in one hand were the elements of Peltier, in the other radiators. And it was necessary to happen to Providence, the old Esky caught my eye.
In general, after a brew, a crazy thought occurred. Slue the refrigerator from computer rubbish. Two radiators were taken, holes drilled. Esky made a hole for the radiator. I twisted everything with bolts and it turned out what happened. Outside, a cooler is installed from the processor, on the inside, natural convection. Pluses = 1) it works.
Cons = 2) one element is small. 3) the cigarette lighter heats up. 4) When working, the element not only moves heat from the inside. outwards, but also produces heat itself. That is, (suppose) when the temperature of the internal radiator drops by two degrees, the temperature of the external radiator increases by four, five degrees
- Tip: You should combine the effectiveness of autothermos and elements dumplings instead or in addition to the accumulators of the cold.
You can imagine your country house in the summer of the year without a refrigerator? I think no. After all, it is at this time of the year that he really needs it. There is a good option to place all the reserves of the cellar, but you need to take into account the fact that not everyone has it, but a small, dark room will not solve the problem of preserving products.
This topic is relevant precisely in the hot seasons. But as the people say: cook the cart in winter!
An expensive electric refrigerator to buy enough from a financial point of view, because not only is it not from cheap pleasures, but it must also be constantly left to be included.
Therefore, there is one very important question: how to “invent” a refrigerator without using electricity?
The Kholodnik bag with a battery is suitable for short-term sorties from the house. Keeps the desired temperature for about a day. The main thing is to take into account that after the time the temperature in the bag expires the temperature of the external environment. But in this case, we are interested in more powerful devices that hold the cold for a long time.
The most ordinary ideas are in virtually in the air, but often many complicate questions and buy things that need to be used only once or two. And then their fate gather dust on the balcony and wait for their time. But there is a person who created the most ordinary refrigerator with his own hands.
- For this, they used:
- – one and a half sheets of foam (width 3 meters);
- – cold batteries. 3 pieces;
- – glue;
- – cattle (reinforced);
- – cattle (ordinary);
- – insulation with foil;
- – Shurups.
Expenses: 75 r., 237 p., 75 p., 90 p., 50 p., 30 p., 9 p.
You can also use gel cooling elements. In this case, the cold will last at least one and a half days.
The most important thing is to glue the seams and joints well. This refrigerator is convenient to place a car in the trunk. The thing is useful both in the country and on the picnic, on the long train and just on a hot day at hand.
In the absence of electricity in the country, a fisherman, the question of storing products always arises. For example, meat products, fish and other things. Products that have the properties of deterioration do not want to throw away, but there is also a huge risk of poisoning. That is why many refuse this type of product or use them in a small amount. A good alternative here is canned food.
But it is important to know that there are ways to store such products without processing and conservation.
The well.known fact that the Earth in a temperate climate freezes in the winter season and finally thaws only at the end of spring. Therefore, in the event that you do not have electricity in the country and there is no cellar, then you can create a mini-chamber. It will be able to build it every couple of hours, and this building will work for many years.
It is a barrel of impressive sizes (preferably plastic), dug into the soil along the very neck. Barrel is sealed, which means they are not afraid of water penetration.
During the preparation of the pit, you should dig it with a small margin, focusing on dimensions. A layer of sand is poured to the bottom of the pit (they make a certain pillow), as well as all the other cracks between the barrel and the walls of the earth.
This process will protect the barrel from pushing out of the ground in the spring of the year.
In order to conveniently get products from the barrel, you can sew a couple of large bags of different shade and sew braid to them. Thanks to this, you will without errors get the necessary products from the cellar.
The cover should completely eliminate any water. If necessary, make it two.layer.
There is also a different danger. mice, rats, insects. But the main ones are ants. These “pests” will most likely try to climb into the cellar for the sake of goodies. This means that the cover should not only be enough elastic, but also weighted.
So that the cellar does not heat up quickly, it is necessary to “plant” it in a place for which the sun’s rays practically do not fall. The best place is the northern part of the slope. In the absence of this place, it is necessary to create it yourself. For example, install any trellis on which plants (liana.like) growing a good shadow grow.
It is comfortable to use a mini-s himged in mid-spring- early winter. The temperature will gradually increase by a couple of degrees, depending on the warming of the earth itself.
Many people know how much the difference in the temperature between the dew and the air. It is this effect that this refrigerator is based. Only water and wind will be needed to work.
This is a basin with water in which a bucket with a lid is located. It must be covered with a fabric that is good to conduct water. Water will soon evaporate. Thus, the temperature in the bucket does not become higher than the dew temperature.
This refrigerator is installed in the shade.
This method requires less trouble, but you can use it even in motion. By the way, this design is well protected from rodents, since they definitely will not be chopped into the water.
Previously, every family had a glacier. This is about the same cellar, but vice versa. It was necessary for storing cold in the summer of the year. For this, blocks of ice were frozen and removed them.
You can do this in your country. This is a regular box, but with a good insulation inside. The batteries are used as source of cold. It can be ordinary bottles filled with water. They will begin to give their cold and melt, cooling the products nearby. The process lasts about 3 days.
This method is the most reliable and least simple.
DIY summer refrigerator for a summer residence or picnic
As we have already said, the main problem for many people is that the blowing in the hot season quickly deteriorates. But there is a way out!
What can be done from the old refrigerator. a top of the self.proceeds
If you have an old refrigerator at home, takes a place, so to speak, but it’s a pity to throw it out, go the other way. Various homemade homes from the refrigerator, which can easily be made with your own hands, will help to use this popular household appliances with the benefit.
This article will talk about what can be done from the old refrigerator. Of course, the article will be useful for those people who do not throw anything out of the house, but try to use as much as possible with the benefit and benefit for themselves.
TOP for self.landing from an old refrigerator
An old refrigerator, even with a burned compressor, can still be useful in everyday life. And if the refrigerator does not cold for a long time, then it can be easily applied to store a wide variety of things.
Even in a non.working refrigerator, you can store vegetables for the winter and blanks. Of course, for these purposes, it is better to unload the refrigerator case to the maximum, remove the liner net in the back, remove the compressor and get rid of all the “insides” of the refrigerator.
Again, for those people who do not imagine their lives without a household, the refrigerator will be a great “base” for making a home.made incubator. Since the case of the refrigeration device perfectly holds heat, the incubator from the refrigerator will not cool down for a long time, which is the key to its successful work.
In order to make an incubator from the refrigerator, it is also better to get rid of everything unnecessary and unnecessary. You must buy an automatic thermostat, which is installed inside the refrigerator case.
On top, inside the device, several electric bulbs are fixed, and in height. trays for eggs. Homemade incubator from the old refrigerator is no worse than the factory. A little imagination over time, and you can even provide an automatic turn of the trays.
The next home.made from the old refrigerator was a small but effective cellar. This homemade is relevant for those who live in their own house. For these purposes, the refrigerator deepens completely into the soil, and a ventilation hole is provided on top of it.
Be sure to provide a sufficient width of the width to the cellar so that you can always use the summer preparations.
For those who are fond of beekeeping, a small hive can be made from the old refrigerator. In this case, the refrigerator chamber is sewn up with a board and equipped in such a way that the hollow frames are placed in it. Many beekeepers also stain refrigerators and specially modernize them for their own needs.
Who loves antiques will surely adapt an old and unnecessary refrigerator under the cabinet. In this case, fantasy simply has no limit! You can change the refrigerator body beyond recognition, paint it or glue it with adhesive tape.
A homemade refrigerator cabinet will be a great place to store a wide variety of things, and even embellish the interior of the house.
Thermal pump from the refrigerator
Have you thought about the old but working refrigerator, you can make a thermal pump. For these purposes, the refrigerator should have a working compressor, you will also need a copper pipe to make a coil and a water heater, with a volume of at least 100 liters.
As a capacitor of the heat pump, it is possible to adapt a stainless tank, inside which a coil of a copper tube is wound. For these purposes, you will have to cut the tank into several parts, and then connect it again. At the exits from the coil, the presence of threads should be provided for connecting pipes from the evaporator.

Do.it.yourself tourist refrigerator
Recently wondered the preservation of products during sorties to nature and so I decided to cut a small refrigerator for trips for a day or two. The goal was not a big dimensional under the most necessary, but also a minimum budget out of sports interest. Initially, the post was not going to do this photo of the manufacturing process. I was asked to attach a photo to my comment, I could not insert them there, and so we are here here.
An extruded polystyrene foam that is sold in construction stores was taken as a basis, a sheet of 1200x600x20. A sheet of such a thickness was chosen because he was in a store for the action and did not have “castles”. The locks “steal” a few centimeters around the edges and complicate the cutting and reduce the finished product. The cut was as follows: the long side is 400×400 mm. 2 pcs, short 400×200 mm. 2 pcs, bottom/cover. 400×240 mm.
We glue 3 mm with a foil insulation on the underfloor-baths foil space, it took about 0.7-0.9 m2. I picked up in the store the one that was stronger to break the layer of foil. I glued to a double.sided tape that was already available. There are self.adhesive options, which is more convenient, but it was twice as expensive.
We make a frame, fasten the sheets with each other with double.sided tape and wood screws. In the background lies the lid already in foil. There was also a small sheet of flexible and not crumbling foam, it plays the role of a protruding element on the lid according to the spike/groove scheme and improves the sealing of the refrigerator camera. On the bottom, it is better to glue the foam layer or an additional layer of foil from the inside for damping and protecting the bottom (the polystyrene foam does not return the form and can)
In order that we do not leave the cold through the cracks between the sheets of foil insulation, we use tape metallized for gluing and protecting the insulation from gaps.
For upholstery of the outside of the case, a cheap plastic lining 3000×100 was chosen, 3 pcs left, as well as a plastic corner 25x25x2700 3 pcs.
For gluing everything and everything in this design, you can need glue that can be used with polystyrene foam (usually on the package it is indicated).
There is no work experience with these materials (assholes) for this almost everything is crooked and obliquely, but it seems to hold. In the photo is an almost ready.made option, except for corners on the sides of the structure.
The lid came less because it was not inhabited by lining, for the opening it could no longer be done and I didn’t think out this moment initially. In the future, it will be necessary to make the following improvements: 1) to make some kind of bottom to the outside of the bottom as legs/stands, they will strengthen the bottom of the deflection.
2) come up with a handle refrigerator (I bow to a canvas loops)
3) come up with the fasteners of the cover to the case so that it does not accidentally fall during transportation and there was sealing.
Useful volume ~ 28-29 liters. The price of the issue was ~ 400 r. Materials (taking into account the sheet of foam according to the action of approximately 80 r.) and glue ~ 170 r., plus the pleasure of handling for several evenings.
I will start the result of testing today and later I will post the report in the commentary. For the dough, 3 life of water will be taken with a volume of 0.5 liters.
If someone else to follow the topic, then I give the final results of the test in the field.
I made clicks of the lid to the box on ordinary Velcro on the 4th sides, one 3 liter bottle with frozen water was invested inside. The initial temperature did not measure, but two days later exactly the bottle did not melt completely, the thermometer showed 5 degrees.
I can conclude that thermobox met my expectations and is working out the minimum that I laid on it. As I understand it from tests, the most important and decisive moment is the tightness of the camera.
P.S. I still have not pulled a bottle from the thermal pulp, I will unsubscribe when the thermometer will show 10 degrees and above.
Well, what a refrigerator is it? it’s just a termm box.
Test results with 3 water bottles of 0.5. Boxing all the time in the apartment at a temperature of 23-26 degrees.2 hours later. 6 degrees; 11 o’clock. 8 degrees; 21 hours. 10 degrees; day. 12 degrees and ice in bottles melted at 95-97.Honestly, I am not very pleased with the result and I will try to make a second test with a large ice.in.law. We can assume that the box worked for a day.
With such products, we have on electric trains, ice cream sellers and drinks are rumbling.
You can fill up 2-3 kg of dry ice to the bottom, cover with a newspaper, it will be better to cool than your home;)
Three plastic one and a half in the freezer, then in your tourist boxing. A good source of cold for a day or more if there are more bottles.
This is the approach, otherwise there was a post about a person who was made of two cardboard boxes and a bag made a cold)
Hm. but there was no thought to throw out the wagging wagging, and the foam is thrown where the screws are where the screws, and blow it out evenly? It would be more accurate.
When I divorced my husband, I was 29 years old and my mother.in.law, when I found out that her son had gone from me to another, sighed condescendingly and said.”Well, yes, he ruined your life, and you already have such an age. “. At the age of 30, my mother began to shame me for clothes, namely a light sports style, rude shoes, short skirts. “At my age” we must wear everything strict and be sure to be below the knee, and you need to forget about bright colors. At work, all deeply married ladies periodically sigh to my 35 and try to persuade at least to do IVF up to 40 years.
In short after 35 years. You are a missing person and only the bottom is ahead, especially if you are a woman.
How to make a refrigerator with your own hands
Having delved into the essence of the work of the Peltier element and how the car refrigerator works, it turned out that its work is to lower the temperature relative to the external, t.e. If on the street is 40C, then different refrigerators reduce it by 12-16C and, as a result, we have 24C, as if not a refrigerator, but a certain prototype of the cooler.
But all auto-cooler auto-cooled!
In my case, you can neglect mobility, why not use water cooling?
Necessary materials: element dumplings; Plastic/plexiglass; Radiators, (one with cooler); Copper tubes; Hoses; Thermal paste; Double sided tape; Kitchen foil; Solder (tin); Water pump/pump; Foam box; Power supply from the computer; Tool with straight hands;)
So let’s go! (photography on a slipper, do not scold)
I bought this dumplier element (thermal pump) on the network (declared characteristics: 70W, dimensions 40x40x3.8 mm., Nutrition 12V).
One side is cooled, the other heats up, a “laying”-“fence” is needed, between the heater and the cooler. At hand was the plafon, Soviet times, 4mm thick.
Having fried him with a lighter, he was convinced of his thermal insulation properties (on the one hand he melted, and on the other finger he did not feel the heat))).
The hole in plastic is almost without a gap, so it is necessary to make chamfers, almost like fatset, so that the excess thermal paste finds a place for themselves and there is no mixture between the layers.
A very important issue of attaching all this kitchen. The Peltier element is in its seating place, in plastic, and is pressed (tightened) from different sides by radiators. It is categorically impossible to fix the radiator to the radiator through plastic, otherwise the whole meaning is lost, t.to. one is cooling, the other heats up, and the mount in each other kills the whole meaning of the structure. Therefore, radiators are attached to plastic, each in their holes. I have two identical radiators on the plane, so I arranged them in this way (see. a photo)
I decided to make the mount itself on screws with a hidden head, with M5 thread, a 4.2 mm threaded hole. We drill, cut.
In favor of the system from copper tubes, and did not lose;) broke all copper bulkheads, attacked copper tubes on the plate, soldered on a gas stove, treated with pipe with hydrochloric acid to plow easily. Tubes of different sizes, then to straighten them, so that hoses are worn normally.
As a result from at room temperature of 30C, for 15. In the refrigerator, it dropped to 10C. The wires of the power supply are heated, and not wonder if 70W/12V = 5.83A. Heat removal is wonderful, copper tubes do not even heat up.
Cool, of course. Only now why Dumpete with a small letter? He tried, invented his effect to you, and you.
For storing products/drinks “in the field” I use the same foam box, but a 5mm foil.foamed insulation on two sides (cover too). 2-3 ice bags are enough and it will be cool inside for 1-2 days (unless you open it). I use cold batteries. Chinese bags of powder flooded with water. When traveling to our sea, sausage, sweets, water in my box were stored for 2 days and nothing went bad and was even cool at the end of the second day.
