There is a lot of dust on the machine outside the air conditioner, will it affect the refrigeration

The dust of the compressor of the external unit of the air conditioner will not affect the refrigeration, but the dust of the external fan and the casing will affect the refrigeration. Because it is necessary to dissipate heat to the compressor through the fan, and to achieve the cooling effect of the compressor by circulating air in and out of the casing.

Causes and solutions for air conditioners not cooling:

1. The compressor has no refrigerant.

, add refrigerant.

3. The solenoid valve is not reversed: detect whether the solenoid valve is normal, and replace the solenoid valve if it is not on/off.

4. System failure: check whether the capillary is dirty, oil or ice blocked, if the air conditioner is not refrigerated when refrigerating, it is generally ice blockage, if the nitrogen blowing pipeline blows out the stolen goods or is not smooth, it means that the dirty plug or oil blockage, if there is no refrigerant in the open system, the refrigerant leakage, check the leakage point maintenance.

5. Compressor failure: the whole machine is not refrigerated, open the system, check whether there is enough refrigerant spray, determine whether it is refrigerant leakage, no leakage, and check whether the compressor is not exhausted.

Of course yes, because the dust accumulation on the radiator will make the heat dissipation effect poor, and the result will be poor refrigeration, so it should be cleaned up, so that the cooling and heating will be good.

Yes, the presence of dust on the outside of the air conditioner will affect the heat dissipation of the refrigerant, resulting in refrigeration.

There is too much dust in the fan outside and needs to be cleaned, otherwise it will affect the cooling effect.

If the air conditioner is covered with dust, it will have a great impact on the cooling and heating of the air conditioner, and it must be cleaned up in time.

The refrigeration principle of an air conditioner.

When the compressor is working, it sucks in low-pressure and low-temperature refrigerant.

Vapor, which compresses the refrigerant into a high-temperature and high-pressure gas, passes through the outdoor unit condenser.

After the drying and screening procedure, the refrigerant is reduced in the capillary and the refrigerant is reduced and depressurized, and the refrigerant becomes low temperature and low pressure and enters the evaporator of the indoor unit.

Because the space suddenly increases and the pressure decreases after the refrigerant reaches the evaporator from the capillary, the liquid refrigerant will vaporize and become a gaseous low-temperature refrigerant, at this time, it will absorb a lot of heat, the evaporator will become cold, and the indoor unit will blow the indoor air from the fan through the gap of the evaporator, and the cool breeze will come out, and the room will be cool. This reciprocating cycle completes the absorption and release of heat through the change of the form of the refrigerant, and realizes refrigeration.

In the process of refrigeration, water vapor in the air.

It will meet condensation, because the evaporator temperature is very low, these water vapor will condense into small water droplets on the evaporator, and over time, the small water droplets on the evaporator will form a water flow and flow out along the water pipe, which is why the air conditioner will produce water, and the reason is here. Sometimes some people will be entangled in their air conditioner emits a lot of water, in fact, this is the same as the air conditioner is always turned on and the indoor air humidity.

The size is related, and the air conditioning has nothing to do with it, rest assured to use.

The heating principle of air conditioning and cooling are just the opposite.

There is a four-way valve when heating.

The solenoid valve parts only need to change the flow direction of the refrigerant in the condenser and the evaporator to achieve heating, at this time, the evaporator of the indoor unit becomes the condenser, and the condenser of the outdoor unit becomes the evaporator, and the indoor unit blows hot air.

The outdoor unit blows a cool breeze, and it becomes a "heat transfer", it's as simple as that.

The outdoor unit of the air conditioner can be said to be the heart of the air conditioner, and the refrigeration and heating system compressor, condenser, gate valve and throttling components, drying screening program, fan and other components of the air conditioner are installed in the outdoor unit.

The external unit is covered with dust, does it affect the cooling and heating of the air conditioner?

The external unit is covered with dust, which of course has an impact on the cooling and heating of the air conditioner. The air from the air conditioner is sucked in from the panels and circulates back and forth.

The fine dust in the room is filtered by the filter so that the small gap between the aluminum sheets of the evaporator will not be blocked, and without the filter, the air volume will become smaller and smaller due to the dust blocking the evaporator for a long time. The cooling (heat) effect becomes worse. Power consumption added.

There is also a new multiplication of bacteria. You have to find a way to match it.

I think there is, it will affect the exhaust aspect, so it would be better to clean it up. And from an aesthetic point of view, being covered with dust is also very disturbing, so it's better to clean up your senses.

It has an impact. It is recommended to clean the air conditioner in time, as the dust will increase over time. Heat dissipation and heat dissipation have a certain impact. Power consumption will also increase.

Summary. Of course there are implications. The dust of the filter will block the air from entering the heat sink, so that the heat dissipation of the air conditioner is not good, causing the compressor temperature to rise and the air conditioner will fail.

Dust can also block the air circulation of the air conditioner, resulting in a greatly reduced air volume of the air conditioner, which ultimately leads to poor heating effect of the air conditioner.

Of course, there is a distribution effect. The dust filtered by the sun wheel mesh will block the air from entering the heat sink, so that the heat dissipation of the air conditioner is not good, causing the compressor temperature to rise and cause the air conditioner to fail. Ash can also block the air circulation of the air conditioner, resulting in a greatly reduced air volume of the air conditioner, and ultimately leading to poor heating effect of the air conditioner.

Can you elaborate on that a little bit more?

What is the impact of knowing that the filter of the air conditioner is dirty? Brothers Rita Shin Fuitan Sakura No. 9 ta received more than 10,000 likes, of course, it has an impact. The dust of the filter will block the air from entering the heat sink, so that the heat dissipation of the air conditioner is not good, causing the compressor temperature to rise and the air conditioner will fail.

Dust will also block the air circulation of the air conditioner, resulting in a greatly reduced air output of the air conditioner, which ultimately leads to the poor heating effect of the air conditioner. Extended information: Air conditioners are divided into single cooling air conditioners and cold and warm air conditioners, the working principle is the same, and most of the refrigerants used in air conditioners before were freon.

The characteristic of Freon is that when it changes from a gaseous state to a liquid state, a large amount of heat is released. When the liquid state changes from a gaseous state, it absorbs a large amount of heat.

That is, first absorb heat and gasify and then liquefy and release heat) air conditioner is designed according to this principle. The electronic defrosting controller controls the defrosting circuit through two parameters: temperature and time. It first senses the temperature on the surface of the evaporator of the outdoor unit through a thermistor, and uses this to control the electromagnetic reversing valve, and at the same time controls the defrosting time through an integrated circuit.

There are generally two kinds of air conditioning defrosting circuits, one is to stop defrosting and let the frost melt by itself, which is not feasible when the temperature is low, and the time to melt the frost is longer, and the air conditioner generally does not use this method. The other refers to thermal defrosting, that is, the use of changing the reversing valve to make the indoor side of the evaporator into a condenser, which can also be regarded as the meaning of the exchange of internal and external machines to achieve the effect of defrosting.

Summary. 1. If the air conditioner filter is dirty but not cleaned in time, the dust on the filter screen may gather on the surface of the evaporator along the gap, and then flow into the water tray with the condensate. 2. If the air conditioner filter is dirty but not cleaned in time, the dust on the filter screen may enter the back of the evaporator with the fan, causing the evaporator to be blocked, resulting in water leakage of the indoor unit.

3. If the air conditioner filter is dirty but not cleaned in time, the owner turns on the air conditioner, the fan motor will start running, and the dust may slowly gather on the fan motor blades, which will make the spacing of the blades smaller, the blowing volume will be smaller, and it will make a loud noise. 4. If the air conditioner filter is dirty but not cleaned in time, if the air conditioning refrigeration function is turned on, the air temperature blown out of the indoor unit will be very low, but it will not blow far, which will lead to the phenomenon that the temperature near the air conditioner is low and the temperature of the whole room is very high. The above is about the impact of dirty air conditioning filters, I believe you have a certain understanding of this, I hope it can help you.

Can you tell us more about that?

4. If the air conditioner filter is dirty but not cleaned in time, if the ridge mold is turned on and the air conditioning refrigeration function is opened, the air temperature blown out of the indoor unit will be very low, but it will not blow far, which will lead to the phenomenon that the temperature near the air conditioner is low and the temperature of the whole room is very high. The above is about the impact of dirty air conditioning filters, I believe you have a certain understanding of this, I hope it can help you.

What happens if the machine filter outside the air conditioner is too dusty, <> the air conditioner filter is dirty and dirty, which will affect its heating effect. Because the dirty filter screen can easily lead to poor exhaust of the indoor unit of the air conditioner, the indoor heating efficiency will decrease; The increase in the number of air conditioners that take longer to reach the user-preset temperature increases. The filter screen is dirty and blocked, which will affect the heating effect of the indoor unit of the air conditioner; This is due to the fact that there is more dust in the filter, which will cause the evaporator to be unable to complete the heat exchange with the indoor air during heating, the room circulation will be slow, the temperature around the indoor unit will be hot, and the temperature in the room will be low, which cannot be well reached.

Since the indoor temperature cannot reach the set temperature, the air conditioner may need to run for a longer time to reach the right temperature, which will increase the power consumption. In addition, the dirty blockage of the filter may also cause dust to accumulate on the surface of the evaporator through the gaps, and flow into the water tray with the condensate, which will block the water tray for a long time, causing water leakage of the indoor unit. Hope it helps.
