The compressor pumps the vapor by means of A different heat exchanger (out of doors condenser) where by warmth is rejected and the recent gasoline is condensed to your heat significant strain liquid. This heat substantial stress liquid is pumped through a more compact copper tube (liquid line) to the filter (or filter/dryer) after which you can on to an expansion machine where by the significant force liquid is minimized to a cold, small force liquid. The chilly liquid enters the indoor cooling coil and the process repeats.
