How do air conditioner work?

Answer 1

Air conditioning works on basic thermodynamics, hot goes to cold. 5 main parts to an AC system: Condenser (usually in front of the radiator), Metering Device (creates pressure drop in the system), Evaporator (located in your cars console which picks up heat), compressor and refrigerant(chemical liquid which boils at low temperatures).

So you turn your AC on and liquid refrigerant flows through the metering device changing it to a low temperature low pressure liquid vapor(mostly liquid). As the refrigerant flows through the evaporator the "hot" air of the car is absorbed into the refrigerant which causes it to boil off into a vapor form. This low pressure vapor refrigerant then flows through the compressor turning to a high temperature high pressure vapor. That vapor then goes through your condenser, and releases heat to the outside air(vapor is hotter than outside air)and turns back to liquid refrigerant. At this point the liquid refrigerant flows back through the metering device and the cycle continues until your thermostat is satisfied, disengaging your compressor.

In short you are taking that hot air in the car and transferring it outside.
