the heat exchanger needs to be after the compressor
as the temp. of the gas is raised during compression
although a heat exchanger before the pump probably
wouldn't go astray as it would raise the efficency of the
pump. however the discussion is moot, the pump from a
household or even decent commercial refridgerator is
no where near capable of delivering the volume required.
