Aircraft air conditioning packs do not use refrigerants or work in any way similar to home or car units.
They take hot bleed air off of the engines compressor core. After passing through one or two air to air heat exchangers to remove most of the heat, air temp off of the engine is in excess of 300-400 degrees C.
It then goes through a cooling turbine, it works similar but completely opposite of a "Turbocharger". The cooling turbine rapidly expands the hot air which cools it to sub zero temp.
then hot air is mixed with the super-cooled air to just above freezing.
It then goes through a water separator to remove most of remaining moisture. Routed through ducts and mixed with more hot air to the desired temp to maintain cabin temp.

Typically an inside HVAC unit that has the evaporator with condensate line and the blower fan.
