What does electricity do to remove heat from air?

Refrigeration cycle. Start with a room temp, low pressure gas. Compress it with a compressor, now you have high pressure gas, but it’s hot from compressing. Then gas goes through an outside unit (condenser) where it runs through a coiled tube and a fan blows outside air across it to cool it. Now you have a high pressure, outside temperature fluid that has condensed to a liquid. Then it goes through a throttle valve, and the pressure drops as it tries to squeeze through the valve to the other side. The pressure drop makes the temperature drop too, so now you have a low pressure, low temperature mix of gas and liquid. This is what you needed, a cold fluid. Then the fluid goes through an inside unit (evaporator) where it runs through a coiled tube and air from the room is blown across it. The air in the room is cooled down by giving heat to the cold fluid, and the cold fluid is warmed back up. Then the fluid gets sucked back into the compressor to start again.
The electricity is used to turn motors that run the compressor, the outside fan, and the inside fan.
