How is it that the air outlet of air conditioner is frosted and not cooled?

Solutions for refrigeration and uncooled air conditioning are as follows:

1. Insufficient or excessive refrigerant in air conditioner: For air conditioner, if the refrigerant is insufficient, it may be that the evaporator pressure is too low, resulting in freezing. Just add enough refrigerant to it at this time. If there is too much refrigerant in the air conditioner, it may also cause the air conditioner to freeze. Because too much refrigerant may flow to the evaporator of the air conditioner, causing it to freeze.

Solution: Ask professionals to deal with fluoride in air conditioners.

2. The air conditioner evaporator is dirty: if the air conditioner is used for a long time, it will be dirty inside. If it is not cleaned for a long time, the heat transfer of the evaporator of the air conditioner may be reduced, resulting in the evaporator's low temperature and freezing.

Solution: Clean the air conditioner regularly.

3. Air-conditioner compressor failure: Long-term use may lead to compressor damage or power reduction, resulting in ice inside the air conditioner.

Solution: Add refrigerant to the compressor to see if it can be solved. If it is not handled properly, only the air conditioner compressor can be replaced.

4. Air-conditioning thermostat failure: Air-conditioning thermostat failure will also cause air-conditioning to freeze.

Solution: Replace the air conditioner thermostat.

5. There is something wrong with the throttle: If the cooling capacity and temperature of the air conditioner are set normally, but the inspection end cannot reach the outlet temperature, it is likely that there is something wrong with the throttle.

Solution: You can clean the filter screen of the indoor unit and improve the operating temperature of the air conditioner, which can speed up the defrosting speed of the air conditioner.
