The air conditioner doesn't need makeup, you're talking about the refrigerator, right?In Pingjiang Mandarin, you take things out and stop them. Use a wooden spatula to chop off all the ice cubes and put things back in. It's more troublesome.

Directly de-energize the four-way reversing valve or remove the temperature sensor of the outdoor unit coil.
However, after doing this treatment, the outdoor unit will not enter the normal defrosting operation when the frost is serious, which will cause a series of problems in use, such as a large deterioration of the heating effect, abnormal compressor or main electronic control components, etc.
Therefore, it is generally not recommended to make such unconventional changes to avoid abnormal failure and damage to the air conditioner.

In the case of frosting of the outdoor unit of the ordinary air conditioner, first of all, the refrigerant of the air conditioner should be added to the air conditioner in time if the refrigerant is insufficient, and after the refrigerant is added, the copper pipe of the outdoor unit of the air conditioner needs to be re-wrapped with the insulation layer, so as to prevent the problem of frosting of the outdoor unit of the air conditioner.
If the air outlet air outlet temperature cannot be detected, and frost occurs in some parts of the air conditioner, then it means that the air conditioning valve is faulty. When the internal unit of the air conditioner is heating, its external unit is cooling out, and the air conditioner condenser will automatically defrost after reaching a certain temperature.
There are two main ways to defrost air conditioners, one is non-stop defrosting, and the other is shutdown defrosting. The shutdown defrosting is mainly by changing the flow direction of the refrigerant, and the high-temperature and high-pressure refrigerant output by the compressor is transported to the frosting heat exchanger of the outdoor unit, so that the frost layer on the outdoor unit melts. The non-stop operation is mainly through the compressor output of a part of the high-temperature and high-pressure refrigeration gas to flow to the heat exchanger of the outdoor unit, so that the temperature of the heat exchanger continues to rise, and the frost layer on the outdoor unit will also melt.

The main reasons for the non-defrosting of air conditioning heating: 1. The ambient temperature is too low, which makes it difficult to defrost the air conditioner. 2. The defrosting sensor is faulty, resulting in the air conditioner not defrosting.
3. The lack of fluorine in the system leads to the lack of heat in the defrosting and thus the defrosting. 4. The control board is faulty, and the air conditioner does not defrost at all. The solution of air conditioning without defrosting 1, use cloth curtains and spray-painted portrait partitions to reduce the room area.
2. When using air conditioners, use heaters or heaters at the same time. Related questions: What to do if the air conditioner has a small wind speed1, the outside ambient temperature of the bright morning wheel is high, and there are more indoor personnel The air conditioner is working at full load.
2. The power supply voltage is too low, which makes it difficult for the air conditioner to start, and it stops or fuses after starting.
For fusing phenomenon, it is recommended to install a power regulator. 3. The air outlet of the air outlet is not large if the temperature of the room is not lowered in the strong cold block, which is because the air filter has accumulated too much dust, and the filter is cleaned. 4. a thermostat.
Improper adjustment. If the air conditioner is not installed in a good position, it will lead to a small air volume in the indoor unit of the air conditioner. How to deal with it:
1. First of all, adjust the wind speed, there is a wind speed button on the remote control board, which can be adjusted. 2. The air conditioning filter is too dirty, and it is blocked by the air intake, take out the filter and rinse it with water. 3. If the air wheel of the indoor unit of the air conditioner is too dirty, you can take a toothbrush and the like to reach into the air outlet to brush.

Heating frosting is generally located on the evaporator of the outdoor unit, when the heating mode is turned on, the outdoor unit absorbs heat and the indoor unit dissipates heat.
When the outdoor unit still needs to absorb heat, the temperature of the evaporator body will drop to below 0 degrees, and the surrounding moisture will be similar to the dehumidification during refrigeration, and it will soon condense into frost.
Treatment plan: This is a normal phenomenon, the air conditioner itself has the function of outdoor defrosting, when the temperature and time reach the set standard, it will automatically defrost, and the problem of frosting can be automatically solved.
-
The defrosting of the air conditioner is a matter of the outdoor unit, the room temperature is relatively low in winter, the heat should be obtained from the low temperature when heating, the temperature of the evaporator of the outdoor unit is lower, it is easy to absorb the moisture in the air and frost, the frost is thick, it affects the heat exchange of the evaporator, so that the air conditioner can not heat, and then the defrosting is needed.
If the air energy heat pump is not defrosted in time, it will cause the frost to become thicker and thicker, and the capacity of hot water will also be greatly reduced, and there may be ice in the evaporator of the unit instead of frost, which may lead to direct production of hot water, and in serious cases, it will also lead to direct shutdown of the unit, so the air source heat pump air conditioning defrosting must be timely, and the frosting of the unit must be closely observed to ensure the normal operation of the unit.
-
The air conditioner will only be defrosted when it is heating in winter, because the temperature of the temperature exchanger of the outdoor unit is very low, frost will occur, and the frost will affect the ventilation and hinder the temperature exchange, so it must be defrosted to ensure the normal heating of the air conditioner.
In fact, the defrosting work of the air conditioner is to switch the circulating flow direction of the refrigerant through the four-way valve, so that the air conditioner is converted from the heating working state to the refrigeration working state, but the indoor unit fan does not work. In this way, the temperature of the temperature exchanger of the outdoor unit is very high, so that the frost melts away quickly. The indoor unit does not work because the temperature of the indoor unit temperature exchanger is very low when the refrigeration is working, so that the indoor temperature will not be reduced.
After the air conditioner is defrosted, it will automatically switch to heating mode.
-
Air conditioner defrosting is due to the presence of water vapor in the air around the outdoor unit when the air conditioner is running in winter heating mode.
If there is no water vapor in the surrounding air at this time, the outdoor unit will not frost when the air conditioner is heating, and there will be no frosting action. Of course, this is the ideal situation.
From the working principle of the air conditioner, if the heating mode of the air conditioner is running in winter, the surface of the heat exchanger of the outdoor unit is seriously frosted, or even frozen, and the air conditioner does not melt, the heating capacity of the air conditioner itself will become very poor, and the heating effect will be seriously deteriorated.
If the icing and frost are too severe, it may cause liquid shock to the air conditioner compressor and cause complete damage. Therefore, the air conditioning unit must be defrosted regularly during actual use to ensure that the air conditioning system can operate safely and normally and has a good heating effect.

The current air conditioner enters the defrosting state according to the following conditions:
1. Detect the temperature of the evaporator coil in the room for a certain period of time, lower than a temperature for a certain period of time, 2. Defrost once for 45 minutes to 90 minutes for continuous heating.
3. Detect that the temperature of the condenser of the outdoor unit is lower than a temperature for a period of time, and many manufacturers' machines decide whether to defrost according to these three points, that is to say, they will be defrosted at least once an hour.
If your air conditioner is heating normally, but the defrosting frequency is relatively high, you should see if the outdoor temperature is too low and the outdoor humidity is too high (especially in rain, snow and fog).
If the heating effect is not very good, a small amount of fluorine deficiency can also cause continuous defrosting.

If you don't defrost the air conditioner, it will reduce the service life of the air conditioner because of the previous ice slag, and to a large extent, let the users who use the air conditioner lose their benefits, so we need to defrost the air conditioner from time to time, so that the air conditioner can serve us well.
-
If you don't defrost it, it will cause you financial damage because of the ice slag inside the air conditioner, which will reduce the life of the machine.

Not all air conditioners have to be defrosted. There are two main types of air conditioners. The first type is a single cooling air conditioner, and the second type is a cooling and heating air conditioner.
Single-cooling air conditioners do not need to be defrosted, because it only turns on refrigeration, no need to defrost, and air conditioners are generally purchased and installed in Guangdong.
Heating and cooling air conditioners will involve the problem of defrosting. The main occurrence of defrosting is in the winter when the air conditioner is used for heating. In winter, the internal unit is heating, but the air conditioner is actually cooling, because the outside temperature is very low, and the air conditioner will freeze when the external machine is cold.
If the air conditioner does not defrost, the ice outside will become thicker and thicker, and it will also affect the heating effect of the air conditioner. So generally speaking, the air conditioner will melt once after about 45 minutes of turning it on. The defrosting time is ten to 15 minutes.
This is for the air conditioner to have a better heating effect.
-
Air conditioning defrosting is in winter, the outdoor temperature will be relatively low, and the heat exchanger of the outdoor unit will leak to produce some frost, which is what we call the frost layer, and in order to avoid these frost layers will have an impact on the use of air conditioning, the air conditioner itself needs to be defrosted.
At this time, the air conditioner will show the defrosting, the air conditioning defrosting is to improve the heat exchange effect of the air conditioner, when the air conditioner defrosts, the internal unit of the air conditioner will not work, only the external unit of the air conditioner will work. This situation is called air conditioning defrosting.
-
When the air conditioner is heating in winter, frost will form due to the low temperature of the temperature exchanger of the outdoor unit (finned aluminum foil). As the frost gets thicker and thicker, it will hinder ventilation and affect temperature exchange, so the air conditioner will automatically defrost it. When defrosting, the internal fan stops working to avoid blowing cold air.
After about five minutes, after the defrosting treatment is completed, the air conditioner will return to the heating working state.
