What power of freezing the refrigerator to choose?
When choosing a home refrigerator, a person wants to get a device with a freezer, which not only freezes products, but also supports a frozen effect for a certain time when turning off the electricity. From this we conclude that for freezers the main indicator is the freezing power. In this article, we will tell you what the power of freezing the refrigerator is. Which one to choose for the home, as well as touch a number of technical characteristics that need to be taken into account when buying.
The power of the refrigerator is an indicator of maximum electricity consumption for the normal operation of the device. Measured in watts (W) and depends on the volume of the refrigerator, compressor, additional functions of the device.
Stages of defrosting of refrigerators
In the No Frost system, automation is engaged in the removal of hoarfrost. Having discovered ice inside the system, the thermostat turns off the compressor. The defrosting sensor starts the heater, the warm air removes the ice, and the thermostat turns on again. This cycle is repeated endlessly.
Difference between Frost Free vs Non Frost Free Freezer
Manual defrosting is much more complicated and is carried out in several stages.
If your refrigerator has a adjustment button, set the temperature 0 degrees. Then turn off the equipment from the network and open all the doors wide open.
Remove all products from the refrigerator and transfer them to a cold place. Frozen semi.Finished products, remove in pre.Prepared thermal packages. If they are not, put the products in volumetric dishes, wrap with a thick layer of newspapers, foil and wrap it with a blanket. Improval thermal insulation save in the container a minus temperature for several hours.
If the refrigerator does not have a special container for collecting condensate, put a layer of loose paper or towel under it. When the ice begins to melt, the water will flow through the floor.
While the cameras are defrosting, clean the refrigerator. Pour the back wall, collect dust and web from the gratings on which Freon flows. Wipe the ventilation and drainage holes with cotton sticks and wash the cameras.
If you have a regular refrigerator with manual defrostation, rinse the drainage holes. Pick a detergent solution into a rubber pear or a large syringe without a needle and upload under pressure in the stock. So you will delete possible sucks.
Peel the sealing gum toothpaste. Apply it on a soft toothbrush or on a hard cloth and gently rub, but do not stretch. If the elastic bands are deformed, they will lose tightness.
Now wait. The natural process of defrosting takes from 5 to 10 hours. You can turn off the equipment in the evening, and start in the morning.
Built.In refrigerators defrost in the same way as ordinary.
Shelves and t °
The refrigerator has different zones, and the temperature indicators are not the same in them. In modern refrigerators, the freezer is most often located in its lower part. In this case, inside the refrigerator, even if the sensor shows a temperature of 4 degrees, it will differ in different areas:
- On the lower shelf. From 0 to 3;
- The next-3-4 degrees with a plus sign;
- On Middle. 4 degrees with a plus sign;
- On the highest. From 4 to 6.
In the freezer compartment, a certain temperature regime is supported, which is exhibited on the control panel. The temperature of the chamber, where the plus temperature will be in the freezer of the refrigerator, does not depend on how many degrees will be in the freezer of the refrigerator. Когда сразу заполняется большой объем камеры, важно устанавливать максимальный холод, чтобы еда равномернее промораживалась. For long.Term storage, −20 ° C is enough.
Important! The indicators are stabilized with a rare opening of the doors.
As for the freezer, here you need to proceed from how intensively (tightly) it is clogged.
If in your freezer, as a rule, there are few products and you do not use it too often, then you should not put the temperature above.14 degrees.
In the case when the freezer is used often. It is loaded by more than half, and among the products most of the meat is, it will not be superfluous to lower the temperature to.20.24 degrees.
The optimum temperature that should be in the freezer is.18 degrees.
The option “Fast frost” or “Super-carbonation” is used to quickly freeze fresh products. As a rule, this happens with.24.30 degrees for several hours.
It is believed that this process allows you to better preserve the taste of vegetables, berries, greens.
Where to put food from the refrigerator during the time of defrosting?
As we already wrote above, it is necessary to put it in a basin, having previously wrapped it in the fabric.
It is best if you put food that is not stored for a long time next to frozen meat or something that does not lose the temperature for a long time. Then you will not have to look for the coldest place in the kitchen or
Take to the balcony. Be sure to put products away from each other that have a pungent smell. For example, fish should not be put in a common container at all, otherwise there is a great risk that all products are “stretched” by a fish smell.
Storage area depending on temperature
Warm air entering the refrigerator with an open door changes the temperature in different zones in different ways. If you measure the temperature in the container for vegetables and on the upper shelf, the indicators will differ. But this is not a sign of improper operation of the refrigerator. Uneven temperature distribution allows you to allocate several storage zones in the refrigerator, each of which has its own unique microclimate.
Distributing products in the refrigerator, taking into account the features of storage zones, you can achieve the following results:
- The shelf life of each product will increase.
- Thanks to the optimal storage mode, the taste quality will remain unchanged longer.
- Proper storage will preserve vitamins and other valuable nutrients.
But in order to achieve such results, you need to understand how the microclimate of each zone is different and for storing which products it is most suitable for.
Freezer, or freezer, is a zone with a minimum temperature. If the refrigerator is two.Chamber, the freezer is behind a separate door and is better isolated from the refrigerator compartment. In single.Chamber refrigerators, get to the products in the freezer, only if you open the common door. This reduces the effectiveness of the refrigerator and overloads the compressor.
Most manufacturers set up control equipment so that in the freezer can be from.12 ° C to.24 ° C. While the step from one control point to another is usually 6 ° C.
In this case, the regimes have the following purpose:
- The standard of operation at the average load on the compressor is the temperature mode.18 ° C. At the same time, the products are well frozen.
- Temperature mode.12 ° C saves electricity, but less effectively ensures the safety of products. It is allowed to turn it on if the loading of the freezer is small and the products freeze on medium mode.
- The maximum load (-24 ° C) is advisable if necessary for quick freezing of loaded products. This mode is turned on for a short time and after 2-3 hours the refrigerator is returned to the standard mode.
Modern refrigerators equipped with an electronic control unit usually have a “fast freezing” program. When it is turned on, the control unit will cool the freezer to.30 ° C, and then after 120 minutes the compressor will return to the usual mode. Fast frost provides maximum preservation of vitamins in berries, vegetables, greens.
This department in the refrigerator is intended for cheeses, herbs, boiled fish, cakes, etc. D. The closed compartment creates a unique microclimate, which is characterized by high humidity at a temperature of about 3 ° C.
The freshness zone is marked differently in refrigerators from different manufacturers. The most common designations are Opti Fresh Zone, Biofresh Zone, Cool Select Zone.
With a freshness zone, the zero zone should not be confused. This compartment (it is not in all models) is designed to store chilled meat, poultry, seafood, fish. The temperature in it does not rise above 2 ° C and does not drop below 0 ° C.
If the zero zone compartment is not in your refrigerator, the conditions close to it are observed on the upper shelf of the refrigerator. Here, products fall into the cold emanating from the freezer (provided that the freezer is installed at the top of the refrigerator).
The temperature on medium shelves is highly dependent on how often the refrigerator door opens. The temperature range characteristic of this storage area is from 3 ° C to 5 ° C. This mode is optimal for storing soup in a pan, finished porridge and other second dishes, eggs, salads, groceries, dairy products, soda water and other soft drinks.
You can not clean the finished dishes in the refrigerator before they cool to room temperature. Hot products greatly increase the temperature in the chamber, which creates a huge load on the compressor.
Containers for vegetables and fruits
Containers for vegetables are usually located at the maximum distance from the freezer. For storage of root crops (potatoes, beets, carrots) and fruits (apples, pears), the temperature in the range from 3 ° C to 6 ° C is optimally suitable. It is undesirable that the temperature in containers drops to 0 ° C and below, as this will lead to freezing of products.

You need to maintain cleanliness in containers for vegetables and the freshness zone especially carefully. High humidity and relatively high temperature is the most favorable environment for the development of molds.
Exotic fruits (bananas, pineapples, maracui) is better not to store in the refrigerator. Due to the fact that these fruits grew in hot climate, the effect of low temperatures leads to rapid damage to delicate tropical fruits.
Shelves on the door
This storage area is the warmest. When opening the door, the shelf is outside the refrigerator, so the temperature here is 1-2 degrees higher than the average. Store a container with butter, eggs, sauces (ketchup, mayonnaise, mustard), non.Alcoholic drinks, drugs (candles, eye drops, and solutions for injection).
NO FROST system
If the refrigerator is badly freezed, the reason may lie in the failure of the No Frost system. There are ice in the cells, because of which doors are poorly closed. It will not be possible to solve this problem yourself. It is required to call the master for diagnosis.
Some users turn off the unit for a while, conduct defrosting and washing of both cameras, rearrange the equipment to another place. However, such actions will not give a result. Only a specialist can understand the problem and fix the No Frost system. So that he correctly identifies the reason for the production of excessive cold, it is not recommended to defrost and wash the equipment.
