Will air conditioner work without air conditioning fan

What will happen if you leave the air conditioner on?

Without a break all year round. from 3 to 7 years, it is as properly in server (round.the.clock work, but there are also cases when, in a year, as a rule, poor air conditioners break). If in the summer. from 1 to 3 months then 7 or 10 years, and maybe more up to 20 years if you follow it.

Anton: In principle, the air conditioner can not be turned off, nothing terrible should happen to him. our air conditioners have been working in this mode for several years, and in the instructions for them it is only written that with long use of condensing water in a wet room, dripping out the furniture can ruin the furniture.

Is it possible to leave a working air conditioner unattended?

Leave the air conditioner on unattended, especially for three weeks. it is dangerous.

Do not sleep all night with air conditioning

There is a risk of infectious diseases, without the access of fresh air in a closed room, a person very quickly processes oxygen and enters the state of prolonged hypoxia, which is primarily reacted by the nervous system, the brain. Children are especially sensitive to this.

Mobile air conditioning with two air ducts

The floor unit with one air duct copes with cooling well, but the main problem in circulation is that only the air mass in the room is subjected to, and if you take into account the closed windows and doors, this can be a problem. In the absence of an influx and air release passing through a heated compressor, the atmosphere is discharged and an oxygen deficiency occurs. The lack of pressure from the tributary through the gaps under the doors, the ajar window, etc. is compensated.D., but the warm air entering from the outside reduces the effectiveness of climatic technology.

But there are mobile floor air conditioners with an additional corrugated pipe that takes fresh air from the street. If the need for significant cooling is small, you can remove the influx from the street by installing the plug, which is usually present in the kit.

Advantages and disadvantages

A device with two air ducts has almost all characteristics, as models with one air pipe. Of the advantages, we note relative mobility, low cost and ease of installation. Of the minuses, noise, the need for constant devastation of pallets with condensate, unaesthetic appearance.

conditioner, work, conditioning

But devices with two air ducts replenish oxygen with a fence of air masses from the street, and this is a significant plus:


The installation of the system with two air ducts does not differ from the installation of the air conditioner with one hose, the difference in the number of holes made in the frame, window or wall. The same applies to the window gateway. there are devices with two holes designed to withdraw two pipes.

The only thing to consider is that the second hole will be used only for needs for high capacities, and accordingly there is no need to constant connection of the hose for air intake. For this case, plugs are provided for the closure of unused holes.

Do not forget about the installation of protective grilles that are delivered in the kit and protecting air ducts from the hit of foreign objects from the street.

Mobile air conditioning without air duct

We explained why the full.fledged cooling of the room requires air to be removed to the external environment. But manufacturers in an effort to satisfy users create floor, indoor portable air conditioners without a duct.

Principle of operation

The absence of an air duct significantly affects the design and principle of operation.

Elements of a mobile air conditioner without a hose for air removal:

  • light housing with wheels;
  • fan;
  • filters. air and water;
  • water container;
  • water pump;
  • Control block.

When turned on, the fan drives the air through two filters. air and water. Water filter is a fine.masculine material constantly wetted using a pump. Passing through it hot air is cleaned, moistened and cooled by changing the state of water from liquid to gaseous (evaporation).

It sounds good, but in fact. the temperature in the room is not able to heat the water to a state of evaporation, respectively, there can be no talk of more or less significant cooling. Yes, air, passing through a wet filter, is able to take water molecules with it, but this is called humidification of air, but not cooling.

In the instructions for mobile floor air conditioners without air ducts, manufacturers warn that the open window is required. an air curtain is supposedly created that prevents heat from entering the street.

In fact constructively, the device is not able to create a veil and heated air freely penetrates the room. And the requirement for open windows, in our opinion, is motivated exclusively by waterlogging, which can cause difficulty breathing in people in the room.

To achieve cooling, such models are often equipped with a cold battery (freeze pack). a container that is filled, for example, with water (as a rule, the container is already filled with a refrigerator) and is frozen in the freezer of the refrigerator, and then immersed in a water container in the air conditioner.

Advantages and disadvantages

The most significant minus of mobile air conditioners without a duct is not able to fully cool the air. But, despite this, you can find pluses.

For tangible cooling, it is necessary to use ice water in the tank or special helium cartridges, previously frozen in the freezer

Household mobile air conditioners without a duct are convenient for a private house and cottage, if you do not need special cooling, but you just need to refresh the air. do not require installation, put it, connected it to the outlet and everything. Also, devices are indispensable when working on heating. portable devices for an apartment, house or cottage are able to warm any room regardless of temperature outside the window.

Do not confuse the “FAN” mode and the “FAN” speed adjustment buttons

FAN mode on the air conditioner does not perform the functions for heating or cooling the room. It just creates an air flow like a fan. This same fan has several rotation speeds. Therefore, the air conditioners must be distinguished:

    The “FAN” mode, which is indicated on the display of the remote control “FAN” or icon in the form of a fan. The modes are switched by the “Mode” button;

  • The fan speed adjustment button, which on all air conditioners is also signed by FAN or FAN SPEED or Speed. With it, the fan speed changes:

The rotation speed button does not include the ventilation mode itself!

How to enable ventilation mode

Ventilation in air conditioners is turned on using a remote control. The inclusion algorithm is quite simple:

Since the ventilation regime in traditional air conditioners does not supply fresh air from the street, the use of this function does not exclude the banal ventilation of the room. Now you understand what ventilation in air conditioners means. I wish you all good luck! Leave Комментарии и мнения владельцев if the article was useful!

Is it possible to turn on the split system without freon?

it is possible, this does not affect the engine in any way. But when the air conditioning will take care, you will need to seriously vacuum the system after eliminating the leak.

Car’s AC Not Cold? Here are 4 at home checks | Accelerate Auto Electrics & Air Conditioning

There is no way to ride on a subje. It is necessary to make a kapets to the compressor otherwise. Since the valves are sticking out without work and the oxidation of the mechanism occurs. Further, when refueling the air conditioner there, they refuel oil, which prevents friction, sticking valves well, and in principle, everything.

What will happen if the air conditioner compressor breaks?

Piston compressors are also prone to jamming. This can happen due to a lack of oil in the system. If the air conditioner compressor is jammed, you will have to replace it. It may also be necessary to flush the system (after all, as a result of wear of the node, a metal chip is formed, clogging the tubes).

During the operation of the car air conditioner, condensate accumulates in its radiator. It is an excellent environment for the propagation of harmful bacteria. over, dust is collected in the air conditioning filters and microbes also start in them.

Compressor malfunction

Even if there is gas in the system, the air conditioner may not cool the air and not develop the desired pressure. There are not so many reasons. The most common problem is the destruction of the compressor itself.

On most machines, it is an axial piston, but there are both in-line and rotor-piston structures. In any case, in its mechanical part there are problems such as bullying, grabbing, the destruction of connecting rods and other mechanical nodes. It happens that valves, fittings, and even joint joints are jammed or flowing.

If the compressor is destroyed, it supplies a lot of garbage to the system, often it damages another knot.

Fortunately, the most common problem of all compressors is the banal refusal of an electromagnetic coupling, in which a simple “clutch” sometimes burns out and wears out, and the electromagnet burns. Also, the coupling often fails through the fault of the bearing.

The simplest external designs easily change in place, even without removing the compressor from the machine. complex designs with built.in sealed couplings are more reliable, but to replace faulty elements will require a serious bulkhead of the compressor itself.

Replacing the support bearing of the coupling will also often require the use of the press, and it will not work to complete without removing the compressor itself from the machine. However, sometimes it is enough to adjust the gap or remove dirt from the coupling, and the knot restores performance.

Long-term overheating and overloading the system most often leads to breakdowns with the safety sensors disconnected, or a lack of or incorrectly chosen lubrication and falling products of the filter-dryer destruction into the compressor piston group.

Malfunctions of the heat regulatory valve and throttle insert

These details are too often forgotten, but, nevertheless, these are one of the thinnest nodes of the entire structure. Their task is to create a pressure difference in the system and provoke the evaporation of the refrigerant.

The main problem is that these are very thin devices. The holes are very small, and the TRV has its throughput is also regulated by the needle. Garbage clogs these holes and violates the operation of the system. When vacuuming before refueling, the system can be cleaned, but the probability of this is small. The increased resistance of the TRV and the throttle insert leads either to complete inoperability of the system, or to its very low performance. Often the compressor simply cannot pump the freon, and the pressure jump occurs with its subsequent leakage.

Systems with the TRV are arranged somewhat simpler, since they work in constant mode and with full evaporation of the refrigerant before the evaporator, and the systems with a battery and a throttle insert have a simpler mechanical part. But at the same time they require control of the compressor using electronics, due to which their “flooded type” evaporator is approximately 10% more effective than the usual. But there is another nuance. The battery must prevent the refrigerant in the liquid phase again into the pump, otherwise it will fail as a result. And with an unheated motor or when turned on in winter, there is a chance to ruin the compressor in this way.

How does your AIR CONDITIONER work?

The systems can also lead to inoperability in the operation of the electronic regulation system.

Fan failure

If the air conditioner fan does not turn on, this is another of the reasons why the compressor and the air conditioner may not be launched. Fan function. additionally cool the refrigerant. However, this element is not in all air conditioners, but a breakdown is quite rare. Symptoms-noise when working or complete absence of any rotation. The temperature in the cabin of the car will be slightly higher.

Among the reasons, worn bearings, violations in the electric part, mechanical defects and damage can be distinguished.

Electromagnetic coupling

This is another reason that can provoke the failure of the air conditioner. This malfunction is quite common. Why the air conditioning clutch does not turn on? It does not work due to the failure of a special thermoresistor, which is located directly in the clutch itself. STO specialists change the non.working detail entirely. However, you can save and replace the resistor with a copper vein. Then you can enjoy the comfortable temperature in the cabin again.

If the air conditioner does not turn on, the reasons do not need to be sought in evaporators, radiators, drive belts. For these reasons, he may not cool the air, but he will turn on and even work.

In most cases, the refusal to turn on due to a small level of refrigerant. In such a situation, you need to go to a hundred, where you can professionally and technologically set up the system. In literally half an hour you can forget about the climate system for several years. You can buy a set for refueling, but it costs quite expensive.

It is best instead of acquiring a set to do prevention, as well as preventing problems. So, in winter, once a week you need to turn on the system for 5-10 minutes. So we will exclude the appearance of condensate and provide lubrication with all the necessary details. Wash radiators periodically. Timely prevention will save serious amounts for the repair and refueling of the air conditioner. And you no longer have to think why the air conditioner does not turn on.

Instead of the conclusion

No manufacturer writes in the user manual that the air conditioner should work without turning it off. Use the device how convenient you are. Less often to turn on and off is not a dogma, but a recommendation. So more convenient and economical for technology.

Structurally mobile air conditioners are different, they also differ in different power, but in general the general principle of operation is the same as that of the “classic” (with external and internal blocks) air conditioners.

Cheap Portable Air Conditioner | Does it Work? [CORRECTION: Swamp Cooler]

The floor (aka mobile) air conditioning cools one and from the air in the room, that is, there is no “suction” air from the outside.

The main difference between a mobile air conditioner and a “classic” and internal and outer block of such an air conditioner is installed by one building.

To decide how long it works without disconnecting, read the instructions for a specific mobile air conditioner.

Among other things, mobile air conditioners have their own drainage system.

Condensate (water) is assembled in a special pallet, the volume of the pallet is different.

I have a mobile air conditioner is equipped with automation, which turns it off if the same pallet is filled with condensate (water).

At the time of filling the pallet can affect the air temperature in the room, the same on the street, the temperature is higher, the more abundant condensate.

Indicative (very approximate, since you need to take into account a large number of individual points) disconnecting a mobile air conditioner when filling the pallet (capacity) with water is 3-5-7 days (but possibly earlier).

This time he can work without a break.

If there is no automatic shutdown, then you need to turn off your own and drain the water from the pallet, this is done about 3-7 days, depending on the conditions under which the air conditioner is operated).

Further, mobile air conditioners are quite noisy devices, since both the outer and internal blocks in one case.

Sleeping in the same room with such a working air conditioner is not comfortable.

I have a special timer in my device, the air conditioner is automatically turned off at night and turns on in the morning.

In this mode, he can work for months, but again, it needs to be disconnected for shortly to remove water from the pallet.

There are mobile air conditioners without pallets, moisture turns into steam when heated and removes through the duct.

In this case, a mobile air conditioner can work out for several months (2-3) without disconnecting without disconnecting.

There is no single figure regarding the time of work without a break of mobile air conditioners, since they are different, adhere to recommendations from the manufacturer.

Cooled. boiled, boiled. cooled down

I propose to very briefly recall the general scheme of a typical air conditioner. We need this for one simple reason: to navigate what elements the sensors can stand on and that they control.

So, we press “a/c” and hear the characteristic click of the compressor. This is at best. Sometimes we do not hear it, but we will talk about suffering just below. What is happening in the car at this moment?

Clicking is a compressor coupling. If it is heard, then the compressor began to work. Although there are such cars, mainly German, in which the compressor always works, but we analyze the most popular and typical scheme. From this moment on, the compressor begins to squeeze the freon and drive it on the tube into the condenser (aka air conditioner radiator). Freon comes there very hot (it heats up when compressed), and in the condenser it must be strongly cooled. Therefore, in most cars, when the air conditioner is turned on, the fan immediately begins to work. This is a very important point, and it must be remembered. So, the fan blows on the condenser, Freon cools in it. What is happening to him? Physics and chemists have already understood everything: it goes into a liquid state. that is, condenses (therefore, the air conditioner radiator is called a condenser, and not just a radiator). From there, a liquid freon flows further-to the filter-dryer (he is also a receiver, a converter receiver or filter-dryer). This is a fairly simple but extremely necessary thing: a long tube inside which is adsorbent (usually zeolite). The main task of the drainer is to absorb all the water that enters the air with air. If this is not done, the water will freeze in the ice, clog the highway, and the air conditioner will not work. And this is the second important position that I ask you to remember. Well, at the same time, the filter-dryer from a liquid freon removes unnecessary mechanical impurities, as a rule-products of the inevitable wear of the compressor.

After the drainage, Freon is ready to fulfill his first task. to quickly become very cold to cool the salon. To do this, he needs to survive another procedure. quickly go back to the gaseous state from a liquid state, that is, boil. This process is accompanied by a large absorption of heat, and the freon is very cooling. Physically, the following happens at this moment: Freon passes through a heat regulatory valve and enters the evaporator, where it boils, cooling the evaporator body. Here, roughly speaking, a fan blows on this case, which drives cold air from it to the salon deflectors. And Freon, meanwhile, from the evaporator again runs to the compressor. He at this moment is still quite cold and, of course, gaseous. That is, ready to contract again, cool, condenses, cleanse, boil and return to the compressor again and again.

In all this rather large system, two areas are distinguished. One of them is the site between the compressor and thermoregulating valve, the second between it (or evaporator) and the compressor. The first site is called a pressure highway (or high.pressure highway), the second. a reverse line (low.pressure highway). They are easy to distinguish by touch: the first tubes with normal operation of the air conditioner will be hot, the second. cold.

This is how a little vulgar, but you can simply describe the scheme of the air conditioner. Now the time has come to return to the important things that I noted in the paragraphs above: by the time the compressor and fan is turned on and to the possible freezing of water. All these processes and their consequences are controlled by sensors, each of which can turn off the air conditioner.

Do not harm!

The most likely opponent of the air conditioner is the low pressure sensor. This is the same sensor that has only two provisions to “turn it on” and “turn off” and uses its second position to open the compressor circuit. He does this in one case. with a critical fall in the pressure of Freon. It would seem what care he cares? He has a matter: there is a lubricant component in the freon that is needed to work the compressor. If the freon is not enough, the lubricant for the compressor will not be enough, and it will fail. However, in a very critical situation, you can close the chain directly, bypassing this sensor. The method is suitable to check whether the compressor is intact. If after that he works, you need not to rejoice, but quickly turn it off. working with insufficient Freon pressure is very harmful to him. Well, look for the reason for the refusal to turn on with the sensor. Most likely, the reason really lies in the drop in pressure (most often the compressor stops working when the pressure falls in the reverse line below 0.7 atm, but sometimes it may be slightly higher. you need to know this parameter for a particular car), but it is sometimes the sensor is to blame. Not everyone can check it, because it happens with a simple dual-pin and more complex three- and even four-contact. Better to do it in the service.

In addition to a low pressure sensor there is a second pressure sensor. high. Remember, I said a little higher that if the filter-dryer does not cope with its task, then water may remain in the freon that freezes easily? Ice is such a car “thrombus” in the air conditioning system. If he clogs the phone, the pressure will grow rapidly, and in the end something will surely burst. This “something” at best will be a pipe, in the worst-an evaporator or any more expensive detail (although often there are so many tubes that you want to sob, especially today). Or maybe the compressor may die.

The high pressure sensor works with an average increase in up to 25 atm, although the system can survive 30 atm for a short time. Long work at too high pressure kills the system, so it prefers to turn off, which helps to make a high.pressure sensor.

There is one sign that is sometimes able to help determine which of the sensors does not allow air conditioning to work. If a low pressure sensor is to blame, then the maximum that will happen after the air conditioner is turned on, it will light up the A/C bulb (and then not always depends on the car). But if a high.pressure sensor is triggered, the condenser fan can turn on. True, this will work only if there is a four.pin sensor. In any case, it is better to deal with this in the service.

What does an inverter air conditioner mean. pros and cons of

Air conditioning is a climatic technique that allows you to create and maintain comfortable conditions in the room.

conditioner, work, conditioning

In the article Types of air conditioners, we examined the main criteria that should be rely on when buying a device.

Next, we describe all the pros and cons of inverter air conditioners so that you decide whether it is worth spending significant amounts for acquiring advertised models.

What is the difference between an inverter air conditioner from a regular

To understand the advantages of modern technology, to begin with, it is necessary to deal with the principle of operation of a usually device called linear.

The climate technique of a linear type works on the principle of inclusion/off. after turning on, the device works until the temperature in the room reaches a given level, and then completely turns off. The temperature of the room gradually begins to rise and when the difference of three degrees between the given temperature and the actual reaches the difference, the device begins to work again. It is such a cyclic temperature change that is put in a significant minus to ordinary devices.

Inverter models do not have a strict definition of inclusive/off. works continuously, adjusting the necessary compressor power. The adjustment is carried out thanks to the inverter capable of converting alternating current into constant and, conversely, while changing its strength.

The inverter in the air conditioner is an electronic unit, dynamically changing the voltage supplied to the compressor electric motor in order to change the rotor speed, respectively, boiling of the refrigerant does not stop-high electricity consumption is excluded due to starting currents.

The compressor at the time of inclusion requires a starting current, which is higher than that of a working engine, plus the evaporator does not take time to reach a given temperature.

Example “on the fingers”: Imagine a loaded cart, to move it, you need to make more efforts (in the case of a compressor it is a current, ampezh) than in the process of movement, when the cart is already rolling by inertia.

It turns out The converter changes the voltage, which affects the engine speed and allows you to produce smoothly adjusting the degree of cooling, depending on the command obtained from the microprocessor analyzing the data coming from the temperature sensors of the air conditioner.

Including the device, we launch it at full power, but when the specified parameters are reached, the engine reduces the speed by a minimum, and smoothly supports the established mode, without waiting for the air to warm up. This avoids temperature jumps and saves electricity and extends the compressor service life.

On the Internet you can see such a delusional description of an inverter air conditioner as: 30% cools or heats the room 30% faster. it will not cool faster or more slowly, if you read the article carefully, you will understand why we call such a description of a nonsense!

Almost forty years ago, the Toshiba inverter air conditioner was a breakthrough in the world of climatic technology. To date, Toshiba devices are considered one of the best and reliable. But other manufacturers did not stand aside and began to use new technology.
