How Air Conditioners Work

Air conditioners are made up of three primary parts. These are, the evaporator, condenser and the compressor. The compressor pumps refrigerant throughout the entire air conditioning system. Refrigerant in a liquid state is pumped from the compressor to the condenser via copper lines. Once the hot liquid enters the condenser it is then cooled and exists the condenser in the form of gas. The gas then enters the capillary tubes where it becomes a liquid, and then enters the evaporator coil. Once in the evaporator coil a fan will blow across the coil forcing cold air throughout the ductwork in your system where it is then expelled through registers into the rooms in your home, cooling the air in your home. The cold liquid will then exit the evaporator coil where it returns to the compressor and the cycle repeats itself.
