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

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.

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.

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. Hello, will the dust of the air conditioner affect the size of the air outlet? Not a big problem.

Pay attention to see if there is a lot of dust on the heat sink of the outdoor unit. If there is a lot of dust, it will affect the heat absorption and heat dissipation of the outdoor unit. The solution is to cut off the power of the air conditioner, use the tap water pipe to spray the heat sink of the outdoor unit with high pressure, wash off the dust, dry it and turn it on.

Hello, will the dust of the air conditioner affect the size of the air outlet? Not a big problem. Pay attention to the hidden defects to see if there is more dust on the heat sink of the outdoor unit.

If there is a lot of dust in the key hall, the film will carry the heat absorption and heat dissipation of the outdoor unit. The solution is to cut off the power of the air conditioner, use the tap water pipe to spray the heat sink of the outdoor unit with high pressure, wash off the dust, dry it and turn it on.

What is the reason why the internal machine is not strong?

The air outlet strength of the internal machine is not large. What is the reason.

1. The most common reason for the small air output of the indoor unit of the air conditioner is the situation caused by the low power supply voltage, such as insufficient power supply in the community, or the poor refrigeration and thermal effect of the air conditioner caused by the unstable voltage during the peak period of electricity consumption. 2. Excessive dust on the air conditioning filter is one of the reasons for the small air output of the air conditioning indoor unit, and this reason is also one of the reasons for a variety of problems in the air Gaochun, such as poor heating effect, small air output, etc., dust clogging the filter screen It is recommended to clean the filter screen, and it is recommended to clean the filter screen regularly. 3. Check whether the high, medium and low relay appliances inside the air conditioner are damaged and faulty, if this is the case, it will also lead to the air output of the air conditioner can not be adjusted, it is recommended to ask a professional master for maintenance.

The solution to the dust jam behind the air conditioner:

1. When cleaning the outdoor unit of the air conditioner, first cut off the power supply of the air conditioner to prevent electric shock. You can directly rinse it with tap water up and down, and put the outdoor unit of the air conditioner with a fin-shaped aluminum foil heat sink.

That is, the temperature exchanger can be rinsed, and the right side of the outdoor unit of the air conditioner should also be rinsed when flushing.

2. If it is inconvenient to rinse with water, you can choose a long-haired brush to clean the outdoor unit of the air conditioner, when cleaning with a long-haired brush, you must use a brush to dip it in water, and rinse the wing-shaped aluminum foil heat sink of the outdoor unit of the air conditioner, that is, the temperature exchanger. When washing, just brush back and forth from top to bottom.

3. When cleaning the outdoor unit of the air conditioner, you can also fill the pressure pot with water, pressurize it, and spray and rinse the cold device of the outdoor unit of the air conditioner. If the swag blocks the air path of the heat exchanger, a vacuum cleaner can be used.

to adsorb the swag of the blocked air path of the heat exchanger. If the air conditioner is in a place that is difficult to reach, you can choose a long water gun to rinse.

4. After the outdoor unit of the air conditioner is cleaned, you can use this time to check the outdoor unit of the air conditioner, check whether the frame screws of the outdoor unit of the air conditioner are loose, if it is loose, it should be tightened and reinforced, and the frame is found to be seriously corroded and should be replaced immediately.
