How does air conditioning work?

Air conditioning works by removing heat and moisture from the air inside a room or building and replacing it with cooler, drier air. This is done through a process called refrigeration, which involves compressing and expanding a refrigerant gas to absorb and release heat.

The basic components of an air conditioning system are the compressor, condenser, evaporator, and expansion valve. The compressor compresses the refrigerant gas, which raises its temperature and pressure. The hot, high-pressure gas then flows through the condenser, where it releases heat and cools down as it passes through a series of coils.

Next, the cooled refrigerant gas passes through the expansion valve, which reduces its pressure and temperature. As it enters the evaporator, it absorbs heat and moisture from the air inside the room, cooling and drying it. The now-warm refrigerant gas then returns to the compressor to repeat the cycle.

The process is controlled by a thermostat, which senses the temperature in the room and signals the air conditioner to turn on or off as needed to maintain the desired temperature. The resulting cool, dry air is circulated through the room by a fan, providing relief from the heat and humidity outside.
