Final answer:
The three main components of an air conditioning system are the evaporator coil, condenser, and compressor, working together to maintain a cooled environment.
Step-by-step explanation:
The three main components of an air conditioning system are the evaporator coil, condenser, and compressor. The evaporator coil facilitates the absorption of heat from the indoor air, turning the refrigerant from a liquid to a gas. The compressor then raises the temperature and pressure of the refrigerant gas and pushes it to the condenser, where the gas condenses back into a liquid, releasing the absorbed heat to the outside environment. This cycle repeats to maintain the desired temperature inside the room.
