A compressor, also known as the “heart” of your air conditioner is a vital and often expensive component of your air cooling cycle. This device keeps your home cool and comfortable during the warm weather season by converting power into energy and circulating the refrigerant necessary for the heat exchange process. Simply put, without a working air conditioner compressor, you don’t have cold air.
How an Air Conditioner Compressor Works
The air conditioner compressor is situated within the outdoor unit. This compressor’s job consists of circulating the refrigerant needed during the heat exchange process through the coils. Think of this as the energy source for the air conditioning system: The electricity that runs through the home AC compressor powers the air conditioner to absorb the heat from your home to formulate cool air and push it back into your house.
The cooling process of the air conditioning compressor starts with the motor. The motor powers the compressor with a cylinder and piston. From there, the home AC compressor raises the temperature and pressure of the vapor refrigerant that leaves the evaporator coil. The compressor must increase the temperature of the refrigerant in order to move the heat from inside the home to the condenser. The condenser will then cool down the heat, “condensing” incoming refrigerant vapor into liquid. The air conditioner compressor, in turn, raises the pressure of the refrigerant to move to the indoor unit. The process then repeats, again and again, creating a constant exchange of heat.
