A rotary positive displacement heat pump compressor and turbine combined in one rotor.

Summary

A novel positive displacement turbine and compressor has the unique capability to efficiently compress and 3,600 run/minute or less. In a heat pump cycle the first 180 degrees provide compression, whilst the second 180 degrees between the condenser and the evaporator inlet provide controlled expansion. The slow speed positive displacement turbine has a low tip speed and therefore low intake losses. The combined effect of low intake loss and positive displacement expansion gives a high intrinsic COP.
