The most important part of the system is the restriction of flow.
The compressor prevents back-flow and maintains pressure against the restriction which could be a capillary tube or expansion device orifice.
It is a venturi effect..... The most amazing part of thermodynamic transformation , without which we have no separation of saturation temperatures.
This is for the apprentices to review from their first week back and to step into the greater world of refrigeration we live in.
I'm always fascinated by the simplicity of this design to achieve a manipulation of energy to create a heat transfer effect.
