When it is hot and your home is cool and comfortable, you may never think about what is going on behind the scenes to make that happen. Just in case the question arises, here is a basic explanation on how AC keeps you cool.
Most residential air conditioners are two-piece units connected together to allow the refrigerant to flow between them as a closed system.
The cooling process is actually a transfer of heat from inside to outside via the closed system.
The indoor unit is usually located in the attic or a closet. It consists of a coil box called an evaporator. The evaporator allows refrigerant (cooling fluid often called Freon) to evaporate and absorb heat. Once the heat is absorbed, the cooler air can be circulated through your home via the ductwork.
The outdoor unit, typically located behind or beside your home, is where the heat from inside your home is dispersed to the outside air. It has a compressor, condenser coil and a fan. The heat removed from your home’s air is absorbed by the refrigerant and pumped to this outdoor unit. As this heat is absorbed and moved by the refrigerant to the outdoor coil, it passes through the compressor.
The compressor has the job of moving the refrigerant throughout the system. As the refrigerant moves through a condenser, a fan delivers ambient air across the condenser coil causing it to cool.
As the process completes, the heat from inside your house is dispersed to the air outside your house. The refrigerant is then pumped back indoors and the whole process repeats.
