How long the freezer keeps cold

What to do if the power goes out in your fridge?

The first thing to do is to keep your fridge closed for as long as possible. This will help maintain a stable temperature for a while. In hot weather and when the ambient temperature rises, you can cover the appliances with a blanket or a thick blanket.

If you are caught in a power cut at home, there are things you can do to help protect your food. The first and most important rule is to keep the fridge doors closed. Your freezer won’t let the food thaw, and your fridge will keep a colder temperature longer.

Important Criteria

Indicates how much food the freezer is able to freeze to.18 ° C for 24 hours.

Safe storage. Manufacturers specify the period during which the temperature inside the freezer will not rise above.9 °C if there is no power supply. An important parameter for village life, where a heavy downpour or wind becomes an occasion for such accidents.

Super-freeze mode. Keeps food at.18°C. And for quality freezing you need a temperature of.24 ° C, or better.32 ° C. This mode is activated manually 12-24 hours before food is put into the freezer and is automatically deactivated 48-56 hours later.

Climate class. Indicates at what room temperature the freezer operates without interruption.

Energy efficiency class. If you want your freezer to keep your energy bills low, then you should give preference to the most economical models of A and A class.

Operation in freezing conditions. Some freezers are suitable for unheated rooms. They work and freeze products even at an air temperature of 15 ° C. They do not have to turn them off in autumn, if you plan to spend winter weekends at the country house. You do not have to take all your harvested vegetables and mushrooms to the city, you can take small portions throughout the winter.

Optional equipment. Manufacturers recommend to connect the freezing chamber through the stabilizer, if the voltage in the network “jumps. Don’t forget to buy.

What does not matter?

Automatic defrosting. In freezers with manual defrosting, ice builds up extremely slowly if properly operated. Laries need to be defrosted every 6 to 12 months. For summer cottage use it is just right.

Type of control. Most chest freezers have mechanical controls. On the bottom of the body there is a thermostat, indicators and a button to turn on the super-freezing mode. Less common are models with push button control. In any case, you will have to bend over to switch modes, but the operation of the freezer is not affected by the method of control.

How to turn on your freezer properly?

You should not overload the freezer compartments with food. They should lie loosely, allowing air to circulate. It is most convenient to pack the frozen products in small portions, so that you can then get the necessary amount of product, without defrosting it as a whole.

When you start such appliances for the first time or after defrosting, they can work for as long as 24 hours without turning off. Only after 24 hours is the refrigerator required to turn off. If you put any food in the refrigerator, it will only make things worse, so wait for the appliances to rest a bit.

How long does the freezer keep cold

Freezer email newsletter. Most interesting news picks.


Cutting off electricity causes a lot of inconvenience to modern man, because almost everything we use, depends on it. And if a non-functioning TV, a vacuum cleaner, and even a computer is a problem, but not a problem, then a non-functioning fridge can create not only inconvenience but also financial loss, and even become the cause of ill health. So it’s better to be prepared for the unexpected and be aware of the measures that can be taken to keep your supplies safe.

A power outage can happen at any time and can be as brief as it is long. And you don’t always know about it if you lead an active life and don’t sit at home. often than not, information about what has happened comes from your neighbors, if you communicate with them. And those who divide their time between the city and the country house can not even know about the fact when and how long there was no power supply in the house or in the country house.

In order to control the work of the refrigerator and the quality of storage of supplies we can use a very simple, but illustrative and effective method. Freeze water in a small container, take it out of the freezer, put a small coin on top and put it in the fridge. If when you return you see a coin on top, then everything is fine, but if it drops by more than a centimeter, it means that the food in the refrigerator has been heated for a very long time and could spoil.

During a power outage, food in the freezer compartment can be preserved in perfect condition. everything depends on the quality of the insulation, the tightness of the doors and the presence of cold accumulators. Each refrigerator manufacturer informs us during what time the temperature in the freezing compartment rises to minus 9 degrees (time of autonomous freezing preservation). For example, the Liebherr SBNes 4265-20 refrigerator, according to the manufacturer’s claim, holds freezing temperatures for up to a day. It is worth noting that most manufacturers have very long cooling times, rarely less than 10 hours (in the category of two-compartment refrigerators).

My Freezer is Cooling But Not Freezing!

To know exactly how your appliances are running, today’s technology is great. Refrigerators are able to report rising chamber temperatures directly to you on your smartphone. Of course, if you’re far away, it won’t save your supplies, but at least you’ll be aware of the problem and can protect yourself from spoiled food.

If a power outage catches you at home, there are a number of things you can do to preserve your food supply.

The first and most important rule is to keep refrigerator doors closed. In this case the freezer will not let the food thaw and the refrigerator will keep a low temperature longer. Opening the door of the freezer and running warm air into it, you should not expect it to hold the freezing for as long as possible.

For more insulation from heat, the refrigerator or freezer can be covered with a thick blanket or quilt, helping to keep temperatures inside the chamber.

Judging by responses of owners of different types of refrigerators, the most convenient in such unforeseen situation are multichamber models with door-in-door compartments, as LG GC-Q 22 FTBKL black. If an adult can get along for quite a long time without chilled foods and drinks, then in families with children it is more difficult. But if juices and baby food are in the mini-bar, you can open it without running heat into the main chamber and quickly get what you need.

Active rescuing of supplies

Of course, if a power outage lasts for a long time, you’ll have to take active steps to save at least some of your supplies.

Dairy and fermented dairy products should be placed in glass, or better yet, in ceramic containers and placed in the darkest, sun-protected place. For better storage in an extreme situation, you can pour cold water, or even better. pour ice, in basins, pots and put dairy products in them (in glass). It is best to change the water more often, keeping it cold. This method allows you to keep food fresh and safe for up to a day.

To preserve meat and poultry, you will also need a container of water, but it must be well salted. This kind of storage will also keep defrosted meat fit to eat for a day.

Fresh eggs can be stored in a cool dry place for a week, so they will not be a big problem.

It is best not to wash fruits and vegetables before eating them, but they are also best served in the coolest place possible. Salads and herbs can be put in a jar with water or wrapped with wet cloths or a towel.

Perishable foods and berries have to be taken out, cooked, and eaten. By the way, if the power outage isn’t too long, you can put the cooked food in the fridge once the power is back on. The shelf life of foods after heat treating increases. So you can save supplies and save yourself a couple of days of cooking.

Products in industrial packaging (tomato paste, canned goods) often do not require refrigerator storage at all, but still check the recommendations on the label. For example, mayonnaise in a closed jar can be stored at room temperature for 4 months, ketchup. even longer. But in open jars and bottles such products are stored only in the cold and significantly less.

Another way to preserve at least some of the food is available to motorists and owners of car refrigerators, because they can operate from the car power grid. For example, First 5170 Grey car refrigerator with a capacity of 32 liters is able to keep the chamber cooler at 18 degrees below the ambient temperature, which means that it is quite capable of creating optimal conditions for storing even delicate foods. An alternative is a thermo-bag with cold storage batteries (just remember that they must be prepared in advance).

How long does a new refrigerator take to get cold??

After turning on the refrigerator to the network immediately place the products inside is not allowed, because the device is gaining cold. It takes anywhere from 5 hours to 24 hours to reach the desired temperature, depending on the settings made by the user, as well as many other factors.

7 to 15 years. Some companies don’t even bother to specify a lifetime in the accompanying documentation. Some companies provide information on the average life span, which gives the consumer a rough guide to how long your refrigerator can last.

How long the refrigerator should work and how long it should rest

There is no definite answer to this question. One refrigerator model may turn on for 2 minutes after 8 minutes of inactivity, and another may turn on for 3 minutes after 6 minutes of inactivity. The ratio of compressor work to rest for these models is 1 to 4 and 1 to 2, respectively.

The ratio of operating time to downtime should be on average 1 to 2. Simply measure how long your refrigerator runs and how long it rests. If the rest time is 2 or more than the operation time, there is nothing to worry about. In the opposite case it is worth reflecting. With possible causes of refrigerator malfunction.

Difference in temperature

You need to know. your refrigerator is not producing cold. It transfers heat from inside to outside. A special gas, freon (chladone, refrigerant) is responsible for this. The better it takes away the heat inside and gives it away to the outside faster, the more effective refrigerator works.

If you set your fridge temperature too low, it is harder for the freon to draw heat from your fridge. And the hotter the temperature outside, the harder it is to dump heat into the air. Accordingly, the greater the temperature difference between the inside and outside of the refrigerator, the longer the compressor will work.

Type of freon

If your fridge is filled with the freon R134a or R12, it cools better. If it is filled with R600a refrigerant, the compressor will have to work longer to lower the temperature. These refrigerants have different characteristics.

Modern refrigerators charge with the refrigerant R600a, more rarely. R134a. You can read more about them in the article about which refrigerant is better, R134a or R600a.

System clogging

Freon circulates through the system in which it enters:

Clogging can occur in any of the assemblies. The cross-sectional area will be smaller and it will be more difficult for the freon to pass through the system. The flow velocity will be reduced and, consequently, the refrigerant will cool the cell less efficiently. The compressor will have to work longer to reach the desired level of cooling.

Compressor capacity

The more powerful the compressor, the more it compresses freon. The degree of compression determines how effectively it can give off the heat to the surrounding air. Accordingly, the higher the capacity, the faster the refrigerator compartment will cool, it will run less.

Insufficient refrigerant

In the previous section, we talked about how the refrigerant (aka Freon, Refrigerant) is responsible for removing heat from the refrigerator. If there is not enough in the system, it will cool more slowly. Lack of freon can cause:

If your refrigerator starts to run longer, and especially if the run time gradually increases, there is likely a refrigerant leak. We recommend you article: How to find a freon leak in your refrigerator and get rid of it.

Evaporator icing

The evaporator is the part of the system where freon expands and its temperature drops below 0 degrees. It draws heat away from the chamber, cooling it. The assembly is usually located behind the back of the compartment, but there are some exceptions.

Moisture can accumulate on the evaporator and turn into frost, snow and ice. They form a kind of “coat.”. It makes the freon not be able to draw heat away efficiently. It takes longer for the refrigerator to cool to the right temperature. To fix the problem, simply defrost the refrigerator.

What is the interval between turning on the refrigerator?

Household refrigerators are turned on 4-8 times in one hour. So the duration of one cycle is from 8 to 15 minutes. The motor only runs for 2 to 4 minutes, blowing cold air inside the cavity.

Most likely, the motor-compressor is out of order: there was a breakage of the winding, an interwinding short circuit or the motor “jams”. Faulty motor begins to run, gets very hot, and to protect against compressor overload, the start/stop relay is activated, and then the motor shuts off.

Why does your new refrigerator make noise??

Make sure to remove the shipping bolts that keep the compressor shock absorber springs compressed during shipping. The function of these springs is to dampen the vibrations that accompany the operation of the compressor. If they are blocked, the sound becomes much louder.

Most refrigerators operate normally with an air temperature range of 16-32 degrees. Although the refrigerators have different climate class, you should not set the temperatures too low in the summer, because this can cause increased energy consumption and strain on the refrigerator.
