# Is it possible to turn off the refrigerator every week

## Do I need to turn off the refrigerator while washing?

Washing the outer part of the refrigerator you need to start by turning it away from the network. This is necessary, first of all, for safety, since contact with a wet rag with a working household appliance can lead to a shock. Be sure to clean the capacitor from dust, which is located behind the refrigerator.

Any electrical appliance must be turned off when wet cleaning according to safety regulations. You can not wipe the on the refrigerator with a wet rag, because water is the so.called bridge. through which an electric current enters a person.

## How to disable the Atlant refrigerator

The designers and creators of the manufacturer of Atlant initially provide for various development of events and sudden circumstances. Mode “Vacation”. One of the current functions all year round. Constant temperature deprives many problems familiar to each owner. The atmosphere inside the cabinet retains the quality of the main products, prevents the development and distribution of bacteria, and also saves electricity, reducing the bill for utilities.

Each manufacturer puts different characteristics in the mode. Let us consider in detail the proposal of the domestic brand:

Activation occurs by pressing the corresponding button.

Electricity consumption reduces almost half.

Temperature range from 10 to 15 degrees above zero.

Some models do not have an appropriate option, but a simple setting of conditions allows you to independently create suitable conditions.

## What is the rate of the norm

There are many circumstances affecting the duration of the compressor. Among them, for example, the conditions of use, the refrigerator model, the volume of the camera, etc. In order to evaluate how effectively the device acts, the so.called working time coefficient is used (K). It can be calculated as follows: K = VRC / (VRC V), where:

WRC. time of the working cycle;.

IMPORTANT! If, for example, the working hours. 20 minutes and rest. 30 minutes, it turns out to = 20/(2030) = 0.4. Experts believe that this is a good indicator.

What are the permissible boundaries of this indicator to? From about 0.2 to 0.6. As a rule, the cycle can be considered normal at 0.5. This must be understood as follows: one half of the time spent falls on the functioning of the device, and the second. to rest.

If the indicator is less than 0.2, then this suggests that the chamber has an elevated temperature, and therefore the unit does not cold enough. It is possible that he has violated the integrity of the cameras. When the value exceeds 0.6, then maybe there is some kind of problem of the refrigerator.

### MY DAUGHTER’S FIRST DANCE emotional

The cycle will be longer when the refrigerator is completely loaded. Products in the unit gain cold as much as necessary, and save it for a very long time.

How often the refrigerator needs to turn on and turn off normally? The best indicator when there are 4-8 inclusions per hour. And the compressor works only 2-4 minutes. The indicator can be considered undesirable when the engine turned on in just an hour only once or, on the contrary, did not turn off at all. This is an alarming signal. So, there are some problems in the work of the unit.

And how much time it takes to turn off the new refrigerator? When you turn on a new unit for the first time, it works without knowing stops, from 2 to 8 hours or more. This is because he needs to gain a suitable temperature.

IMPORTANT! In the models that have the No Frost system, immediately after starting and freezing, the thawing mode begins to work. It is carried out due to the thermostat and the heater of the evaporator. In this case, the working cycle mainly lasts 9-16 minutes. To cool, he needs 2-5 minutes. In the remaining time, the process of thawing is carried out.

## The “Vacation” mode in the refrigerator. what it is

Many modern models are equipped with a “vacation” mode. it allows you to not turn off the equipment completely and set the temperature of about 15 ° C. With a long absence of a house, manufacturers recommend using this mode, having previously removed all products or leaving a minimum.

### A brief description of the features of the “Vacation” mode in the refrigerators

Holidy mode to maintain a stable temperature of about 12 ° C. This function will allow the owner not to worry about the fungus and an unpleasant odor. Some LG refrigerators have an antibacterial seal for additional protection.

In the new Samsung models, the intellectual mode displays the technique into a “vacation” state, while only the freezer works.

Using one button, the technique goes into an economical mode, allowing you to use up to 40% less electricity. Depending on the model, a temperature of 10 ° C to 15 ° C is set.

Do not be discouraged if your refrigerator does not have such a function, it has recently appeared and not all manufacturers are found. You can independently adjust the temperature and save the consumed electricity.

## Why the refrigerator cannot be immediately included in the network immediately after disconnecting?

At the time of starting the engine, this element should be cold or barely warm. Therefore, after disconnecting, he needs time in order to cool to the required temperatures. With a momentary launch of the refrigerator after turning off, the engine operation will not be able to start, which will lead to the inclusion of emergency protection.

In any case, wait a minimum of 3-4 hours, and then turn on the equipment into the network through the extension cord. If you transported the refrigerator yourself or delivered it in a horizontal position, then it will be better if it just spares at least a day with open doors and boxes (as in the photo).

### How to protect the refrigerator

To protect homemade refrigerator equipment, refrigerators, air conditioners and other compressor equipment with a similar mechanism of work, delays with a delay, inclusion timers and voltage relay are used. over, the latter will be more preferable since in addition to turning on with a delay, it will protect your equipment (refrigerator) from a dangerous increased and too low voltage of the power supply network.

You can use the voltage relay for such protection in different ways and models of the relay themselves, they are in the DIN-rack in electrical panel or for example, voltage relay. “socket”

or for example mounted voltage relay in the network “filter. extension”.

Regarding the installation, if on the DIN-rack (as preferable), it can be two options: the relay can be put one on the whole house (apartment) or you can put a separate relay on an electric fishing line for the trimmer of the refrigerator. Of course, the latter option will be more correct and practical, but it will pass to purchase an additional voltage relay, you need a free space for its installation in electrical panel and you need that same separate electric fishing line for a trimmer, which is coming from the outlet of the refrigerator to the electrical panel from the voltage relay.

If you put one relay on the whole house (apartment), the “safe” inclusion time in it will force you to wait, for example, turning on the light in the house after the restoration of electricity on the network. Agree 10 minutes to wait in the dark is not very happy. But if there is no other option yet, the time of safe voltage restoration can of course be slightly reduced. The instructions write about 10 minutes, but in practice, the pressure in the refrigerator is aligned on average in 3-5 minutes, it all depends on the brand of the device and the compressor operating time before disconnecting.

For a more reliable, durable and safe operation of your refrigerator, a separate supply line for a trimmer with its RCD and voltage relay is still recommended. But how to set up voltage relay? The optimal settings voltage. 190. 245 volts (everything that will be cut off) the voltage restoration time after an emergency shutdown of the relay or just turning off the electricity on the network, can be configured in the range from 5 to 10 minutes.

## Why the refrigerator cannot be immediately included in the network immediately after disconnecting?

At the time of starting the engine, this element should be cold or barely warm. Therefore, after disconnecting, he needs time in order to cool to the required temperatures. With a momentary launch of the refrigerator after turning off, the engine operation will not be able to start, which will lead to the inclusion of emergency protection.

## Is it possible to save on energy by turning off the refrigerator for 1-2 hours every day?

Now that I am looking at home automation, I think about the automatic power outage of the refrigerator from 3 to 5 in the morning. Given that modern refrigerators are well isolated, it must withstand 2 hours of cooling without food.

If I start this project, will I see a significant reduction in my monthly electricity account?

This can ultimately cost much more. From the point of view of buying a new refrigerator: DIY.stackexchange.COM/QuETIONS/5990/.

@ Level1coder, you can save a lot of electricity, Not at all Having a refrigerator. Why do you need a refrigerator at all?

Modern refrigerators are very effective in using electricity, so the savings will be insignificant. Attention to other areas of using electricity will pay off better.

You need to conduct an experiment to confirm this, but I think it will be a false economy.

Despite the fact that the refrigerator is well isolated, it will heat up for a certain amount. Then, when it turns on again, cooling should work more hard / longer in order to reduce the temperature again, possibly using the same (if not large) energy in the process.

Let the thermostat do your work and keep the refrigerator using small energy for 24 hours to maintain a constant temperature.

You will save more energy, opening the refrigerator less often during the day.

@Chrisph ahead of me. Thought about the same. and repeated shutdown and turning on the refrigerator can lead to a load on the compressor, instead of constantly maintaining the low working current of the compressor. It would be more profitable to look at the energy consumption ratings of the existing refrigerator and think about buying a more environmentally friendly refrigerator.

Absolutely true. At night, when no one opens the door, it is quite possible that the built.in thermostat already gives you 2 hours of downtime of the compressor in any case.

1, but this is true only if you pay the same bet throughout the day. You may have a plan with two tariffs. Let’s say n cents per kilowatt at night and 3n cents per kilowatt-hour at another time. Such plans are typical in some regions. If so, then it really makes sense to transfer all cooking (how convenient it is, of course) and the same thing will make sense for the refrigerator. If you turn it off, say, four hours before the night tariff enters into force, then it will then consume the same energy when a cheaper night tariff is valid, and this can save you money.

This answer is incorrect and was proved incorrectly in scientific research. It’s all about energy saving. You compare the cooling of things to permanent 35 degrees or allow things to sit for several hours until possible 40-42 degrees and instantly cool up to 35 degrees once. In addition, the empty the refrigerator, the more incorrect answer. a refrigerator with several objects does it completely wrong. Now there is a reverse side. dairy products will deteriorate faster, the compressor on the refrigerator can be overloaded, but this is not part of the question.

To remove a certain amount of heat from the refrigerator, a certain amount of work is required. You can do this now or later, but this is the same amount of work. Thus, the first approach says that you do not save anything (or do not lose).

Turning on and off the engine requires some energy, but it is quite small compared to the actual cooler load.

How quickly the refrigerator loses heat, depends on the difference in temperature. thermal insulation and skin surface area. So:

If the refrigerator becomes warmer, it will facilitate its work. So let your home be cooler. Or put a refrigerator on the street in the shade in the summer.

### How long can a fridge be turned off?

A modern, well.insulated block consumes less energy.

All other things being equal, a smaller refrigerator consumes less energy. Most of what we put in our refrigerator, our ancestors left in a cool cellar or just on the counter. You could accept some of these habits and reduce your refrigerator.

In winter, I keep heat in my house using an electric furnace connected to a thermostat. All the energy that enters my refrigerator comes out in the form of “unnecessary” heat, making my house a little warmer. If I optimized my refrigerator, then my stove would just run to make up for this. So almost nothing will work out, at least in winter. (In the summer, if you run the air conditioning, you pay twice for cooling food!)

I use Kill-a-Watt to measure energy consumption of my devices and computers. He does not measure everything (240 V elements, wired devices), but he helped me learn a lot about where my strength is going.

Modern refrigerators use only 70 a year. Thus, 2 hours a day, when the refrigerator does not open, it costs less than a penny per day.

I have a friend who seriously refers to electronics. He did exactly what is described here. He built a controller / timer, which turns off the power of the freezer / refrigerator during peak hours (from noon to 6 pm). It also turns off when the temperature reaches 6 degrees Fahrenheit; If the temperature reaches 20 degrees Fahrenheit, it turns on again.

He demanded (and received) the electricity meter of the use of time from the energy company, so it can optimize the price / use formula (mainly avoid peak times). He says that over time saved a lot of money. He built his control unit and measures a kilowatt hours of use transferred to pricing.

OK, I sent my email address in the profile. I have a very simple mission: to convey to the public my friend’s idea of ​​energy conservation using freezers / refrigerators. He doesn’t want to make money. He is ready to provide schemes for free. Please contact me if you are interested (especially Chrisf).

There is one basic reality that is missed from several posts on this issue. No matter what energy is used. gasoline, electricity, wood, coal (or even atomic energy). more energy is required to get movement, cooling or heating than to keep movement, cooling or heating. If you doubt this basic scientific principle. although stated in terms of non.professional. just jump onto a bike and start to trade. You will quickly find that it is much more difficult to make it move than to keep it on motion. The same is true for the car, and that is why the highway mileage is much higher than the mileage around the city.

## If you leave the refrigerator on

Perhaps nothing terrible will happen, you will return and continue to use it, as before. But do not forget that there are threats that can seriously affect the stability of work.

Follow a few simple rules before leaving:

• Be sure to check the products for freshness: frozen vegetables will be subject to your return, but the left milk can play a cruel joke.
• Always get meat products. If the electricity is disconnected or something happens with the refrigerator, you will find an unbearable smell inside, which is very difficult to get rid of.
• Do not leave equipment near batteries or water pipes, the effect of heat and moisture will irreparably affect the work of the refrigerator.

Now you know how to prepare any model for a long departure. If you are still afraid to throw equipment, seek help from relatives or neighbors who will help you look after the apartment in your absence.
