Closed Loop - Refrigeration

A non-phase change fluid (supercritical CO2) is worked between a 3:1 volumetric offset from each half of the FeTu device.

When applying power and rotating the driveshaft, the volumetric offset between top and bottom creates a situation where the small chamber will dose less CO2 to the pipework than the large chamber extracts (LHS), whilst the large chamber will dose more CO2 than the smaller chamber can take out (RHS).

This creates a low pressure on the LHS and a high pressure on the RHS. This pressure differential will subsequently create a low and high temperature respectively.

Heat is added to the LHS for AC cooling/refrigeration whilst heat is absorbed on the RHS with a heat sink.
