Why is the refrigerator hot inside and cold outside?

There are several reasons for this:

1. The high-pressure pipes on both sides of the refrigerator cause the outside of the refrigerator to heat.

When the refrigerator is designed, for the beauty of the refrigerator and the convenience of cleaning, the high-pressure heat pipes are buried on both sides of the refrigerator. Since the high-pressure heat pipes are hot, it is normal for heat to be generated on both sides of the refrigerator.

2. The heat outside the refrigerator is caused by the operation of the compressor.

The refrigerator is refrigerated by a compressor and recycled by freon.

Frozen. When the refrigerator compressor.

When running, the freon cycles and the radiator takes away the heat. The radiator of the old refrigerator was exposed. A row of black tubes can be seen behind the refrigerator.

Now the refrigerator is built in for aesthetics, so you can't see it, but you can still feel the heat, so it's hot outside.

3. The heat dissipation of the running refrigerator causes the outside of the refrigerator to heat up.

Knowing that any substance has to release heat after liquefaction and it has to absorb heat while it is vaporized. This is the most common physical phenomenon. Air conditioners and refrigerators use this principle to liquefy refrigerants.

The heat is released, then allowed to evaporate and absorb the heat.

The location where the heat of liquefaction is released and the location where the heat is absorbed by evaporation cannot be in the same place, otherwise it will not work. In the refrigerator, the radiator is on the outside of the refrigerator. The purpose is to dissipate heat, but it can still be felt when the heat is removed, so the outside of the refrigerator is hot (hot).

A refrigerator is a refrigeration device that maintains a constant low temperatureIt is also a civilian product that keeps food or other items in a constant low temperature state. There is a compressor and an ice machine in the box.

Cabinets or bins for freezing, storage bins with refrigeration units. The volume of a household refrigerator is usually 20-500 liters.

In 1910, the world's first compression-type refrigerated household refrigerator was introduced in the United States. In 1925, the Swedish Lido company developed the household absorption refrigerator. 1927 General Electric Company of the United States.

A fully enclosed refrigerator was developed. In 1930, air-cooled continuous diffusion absorption refrigerators with different heating methods were put on the market.

In 1931, a new type of refrigerant freon was successfully developed, and the production of household thermoelectric refrigerators began in the second half of the decade, and China began to produce refrigerators in the 50s.

Normal should be cold on the inside and hot on the outside. Because the inside of evaporation and refrigeration must be condensed outside to produce heat.

The inside of the refrigerator is hot, but the outside is cold, it may be that the cold silver tube is blocked by ice, and the refrigeration pipe is not smooth, so you need to melt the ice and turn the refrigerator on.

Refrigerator refrigeration relies on a fan to accelerate heat dissipation, and then another part of the machine cools, which will naturally heat up after a long running time.

It could be that your refrigerator is out of style, Ann said he wouldn't be in this situation.

The refrigerator gets cold when it's no longer in use.

First of all, we need to know if there is heat outside the refrigerator.

Then this is a normal phenomenon. On the contrary, when the outside of the refrigerator does not heat up, it is a real problem, when we often feel that the refrigerator is hot, this indicates that the refrigerator is in normal operation, so we have nothing to worry about. So why is it hot?

We've summarized some of the reasons.

1. When the compressor inside the refrigerator extracts the hot air in the refrigerator, it passes through its own heat dissipation part and extends to the heat preservation part of the refrigerator, that is, the outside of the refrigerator is hot when we touch it.

2. So where is the specific place for heat dissipation? In the first refrigerator, its heat removal part was a black tube, and today's refrigerator will be installed on the side in order to look better, some are behind the refrigerator, but it is located in the heat storage part.

3. Freon in the refrigerator.

It will suck up most of the hot air, and the compressor of the refrigerator with electricity will be.

When you start working, you will turn the freon into a liquid, and if you use it repeatedly, you will suck out all the heat in the refrigerator.

At this time, the heat dissipation parts on the two sides or back of the refrigerator will play its role and slowly disperse the absorbed heat, which is the reason why we usually feel the heat of the refrigerator itself. It's not that the refrigerator is broken and can't be used.

To sum up, there is nothing terrible about the refrigerator heating up, it is a super normal thing.

The outside of the fridge is always hot and does not get cold. Since the heat dissipation pipes inside the refrigerator are distributed on both sides of the refrigerator, the heat is circulated through these pipes, and the temperature on both sides of the refrigerator will be felt high when it is used for a long time. If the indoor temperature is relatively high, especially in summer, due to the increase in the workload of the refrigerator, the temperature on both sides of the refrigerator will rise accordingly, and the phenomenon of hot hands will appear, which is a normal phenomenon.

Attention to the daily use of the refrigerator:1. For its placement, it must not be placed in a place close to the heat source, otherwise it will affect the heat dissipation of the equipment itself, increase the power consumption of the spine, and shorten the service life.

2. Do not use the same socket with other electrical appliances, otherwise it is easy to regret the phenomenon of short circuit.

3. Do not stop using it for a long time, otherwise it is easy to corrode the internal pipelines and lines.

It's normal to have a fever, so there's nothing to worry about. If it is hot to the touch, and the refrigeration effect is still very good, it is recommended that you turn off the thermostat a little smaller. The refrigerator is placed in a place that is conducive to heat dissipation.

The core of the refrigerator is in the compressor, the compressor has refrigerant (refrigerant) in it, the refrigerator is energized and operated, the compressor is operated, the refrigerant is transported from the pipeline, and when it passes through the evaporator (on the inner wall of the refrigerator), it evaporates and absorbs heat and takes away the heat in the refrigerator (so the temperature in the refrigerator will be reduced.

After the heat is taken away, the refrigerant and heat pass through the capillary, filter drier, and condenser (on the outer wall of the refrigerator), and the heat is dissipated because of the condensation, and the heat taken away is released (so the temperature outside the refrigerator rises), and you touch the outer wall of the refrigerator, you will feel "hot hands".

When the refrigerator is running, this process will be constantly circulating, so the heat dissipation and heat absorption will also be constantly circulating.

After reading the working principle of the refrigerator, do you know why the refrigerator is cold inside and hot outside?

This working principle is actually the same as our air conditioner, except that the compressor of the refrigerator is under the refrigerator, so the heat transported is around the refrigerator. The outdoor unit of the air conditioner is disturbed outside, so the heat transported will be carried out of the house.

The most important thing is the refrigeration method and mechanical operation of the refrigerator, because the cooling method in the refrigerator is refrigerated by some chemical reagents, and from a physical point of view, the conversion of capacity is regular, so the heat released by the chemical reagents inside the refrigerator through refrigeration is conducted to the outside through the refrigerator, so the inside is cold and the outside is hot. In addition, because there are some machines that use electricity in the refrigerator, after using electricity, the machine will also cause some heat, and finally conduct it to the outside of the refrigerator.

In the process of cooling the refrigerator with the condensate, the condensant absorbs the heat in the refrigerator and reduces the temperature inside the refrigerator, and the condensate absorbs the heat in the refrigerator at the same time, but there is no way to cancel the heat directly, and the heat can only be conducted to the outside by conduction. So when we touch the surface of the refrigerator, it's hot.

On the other hand, the refrigerator uses electricity, because some machines in the refrigerator, such as refrigeration machines, need to use a point to start the refrigeration machine, and then the machine will produce heat in the process of operation, and the heat is directly conducted through the outside of the refrigerator, if it is left in the inside of the refrigerator, it will lead to the heating effect in the refrigerator is not very good, and even lead to the phenomenon of not refrigeration in the refrigerator, so the general machine is released through the back of the refrigerator after work. The heat is then released to the outside world.

Generally speaking, it is caused by the mutual conversion of energy, because heat is a kind of energy, which cannot disappear out of thin air or become cold directly, but is transmitted to the outside world through conduction. Refrigerator refrigeration is carried out by the action of machines and condensants, and because the heat generated by refrigeration is conducted to the outside world, the inside of the refrigerator is cold and the outside is hot.

There is a compressor inside the refrigerator, and the compressor has Frion or refrigerant to cool the refrigerator. The outside is hot because the compressor will heat up when it works, and the inside has to be blown with a small fan to help it dissipate heat.

Because there is a refrigeration system inside, it is cold inside, and the refrigerator needs to dissipate heat, so it is hot outside.

This is a very normal situation, it is related to the motor, it is hot outside, which means that the motor is running.

Hello dear<>

Glad you asked why the evaporator of the refrigerator is frozen and cool. The condenser is hot on the outside and acts as a heat dissipator. The exterior heat is due to the condenser (radiator) of the refrigerator on it.

The following is actually the room temperature, but because there is no hot Zen guess ant in the installation period, it feels "cool" compared to the above, if it is really cold, it may be that the refrigerator insulation layer is not done well. First of all, the instructions of household refrigerators generally state that direct sunlight is prohibited. So it's definitely harmful to the machine.

Now let's talk about why it's bad. 1. The direct impact is power consumption. Because direct sunlight will cause the heat exchange effect of the condensation embedr to deteriorate, which is equivalent to increasing the ambient temperature.

2. Direct sunlight tends to shine directly on one side, resulting in a temperature difference between the two sides of the refrigerator. As a result, for most refrigerators with non-bottom condensers, the temperature of the condensers on both sides is uneven, and as a result, various system problems can occur. 3. Direct sunlight may cause the refrigerator shell, discoloration, brittleness, cracking and various unknown omen cover problems.

However, it is normal for the outer wall of the refrigerator to heat up when it is working, because what is needed is the condenser to dissipate heat.

Because there is a refrigerator inside, but not outside.

It's cold inside, that's hot outside! You know, there's a theorem in nature! Objects absorb heat, let it cool, let it cool, and it absorbs heat!

The working principle of the refrigerator: when working, the gaseous refrigerant is compressed into a high-temperature and high-pressure gas through the compressor, and then enters the condenser. The condenser is equivalent to a heat exchange device, which converts the gaseous refrigerant at high temperature and high pressure into a liquid refrigerant at low temperature and high pressure.

The liquid refrigerant then passes through the expansion valve, the so-called expansion valve is a throttling device, because the refrigerant flowing out of the expansion valve is stationary, so the pressure drops after the refrigerant comes out, and the temperature gauge consumption continues to decline, (refrigerators are generally replaced by capillary expansion valves.) Due to the sudden change from the cow's head to the tube, it can also produce a throttling effect) becomes a gas-liquid two-phase, and then enters the evaporator, at this time, the refrigerant is transferred and gasified in the evaporator, and returned to the compressor as a gaseous refrigerant at high temperature and low pressure for further circulation. This causes the space inside the refrigerator to become colder.

The exterior of the refrigerator is caused by the heat dissipation of the compressor and the heat inside the refrigerator through the refrigerant.

<> refrigerator has a compressor inside it, and there is a freon or refrigerant in the compressor to cool the refrigerator. It's hot on the outside because the compressor gets hot while working, and inside it has to be blown by a small fan to help it cool down. That's why we feel hot outside. "

When the refrigerator compressor is working, the heat inside the refrigerator should be distributed to the outside through the refrigerant through the radiator under the housing. The refrigerant is very hot because it generates a lot of heat when it is compressed from gaseous to liquid state. When the compressor is not working, there is no hot reed.

This process is the basic process of the refrigerator working, and it is very normal.

Do a detailed explanation of the problem for a detailed interpretation of the problem, I hope it will help you, if you have any questions, you can leave me a message in the comment area, you can comment with me a lot, if there is something wrong, you can also interact with me more, if you like the author, you can also follow me, your like is the biggest help to me, thank you. That's all for sharing, if you like me, please follow me. If you guys have any ideas, you can let us know in the comments below.

Because the refrigerator needs to dissipate heat when it is working with electricity. The working principle of the refrigerator is to compress the air through the compressor to achieve the effect of refrigerating the royal shot, and the compressor needs to scatter the heat.

1.When the compressor inside the refrigerator extracts the hot gas inside the refrigerator, it passes through its own heat dissipation part and extends to the insulation part of the refrigerator, that is, we feel that the outside of the refrigerator is hot. 2.

In the first refrigerators, its heat removal parts were a black tube, but today's refrigerators will be installed on the side in order to look better, some are behind the refrigerator, but they are located in the heat storage part.

The main reason for the heating on both sides of the refrigerator is that the cooling pipes of the refrigerator are mostly located on the two sides of the refrigerator. When the compression burner is working, the heat will circulate through these exposed pipes. According to the law of conservation of energy, the amount of heat emitted by a refrigerator produces as much cold energy as possible.

Therefore, the refrigerator has been used for a long time, especially in the hot summer, and the temperature on both sides will be very high, even very hot. So it's normal for both sides of the refrigerator to be hot or hot. Although it is normal for both sides of the refrigerator to heat up, some improper behaviors can also aggravate the heat value of the refrigerator case.

The above is the specific cause of burning on both sides of the refrigerator and related solutions.
