Air conditioner

How it works...

An air conditioner is able to cool a building because it removes heat from the indoor air and transfers it outdoors. A chemical refrigerant in the system absorbs the unwanted heat and pumps it through a system of piping to the outside coil. The fan, located in the outside unit, blows outside air over the hot coil, transferring heat from the refrigerant to the outdoor air.

Most air conditioning systems have five mechanical components:

• A compressor

• A condenser

• An evaporator coil

• Blower

• A chemical refrigerant
