How to solve if the air conditioner is not cooling

If it is not in the cooling state, we can adjust it to the cooling mode; if the dust accumulation of the air conditioner severely reduces the cooling function, we can find professional personnel to disassemble the evaporator, fan blade, and filter. Completely clean up; if it is because no refrigerant is added, then we can add refrigerant.

Refrigeration, Air Conditioning Compressors: Reciprocating, Rotary, Screw, Centrifugal, Scroll

What is Refrigeration Compressor The compressors are one of the most important parts of the refrigeration cycle. The compressor compresses the refrigerant, which flows to the condenser, where it gets cooled. It then moves to the expansion valve, and the evaporator and it is finally sucked by the compressor again. For the proper functioning of the refrigeration cycle, the refrigerant must be compressed to the pressure corresponding to the saturation temperature higher than the temperature of the naturally available air or water. It is the crucial function that is performed by the compressor. Compression of the refrigerant to the suitable pressure ensures its proper condensation and circulation throughout the cycle. The capacity of the refrigeration or air conditioning depends entirely on the capacity of the compressor.<img src="{{media url=&quot;422C8FF7C729C6E9A7416FCA7C2EB508849153E1_large.jpg&quot;}}" alt="" />
