Ericsson Cycle Heat Pump

Summary

Researchers at Purdue University have developed a heat pump system that is a practical application of the Ericsson cycle. It can be constructed primarily using existing equipment and technologies used by the HVACR industry. It has a high theoretical and attainable coefficient of performance, operates at pressures similar to existing heat pump equipment, and uses environmentally benign refrigerants. The system is scalable and can be used for refrigeration, comfort cooling, and heating. Cryogenic applications are also possible. The machine can also be designed to operate as a heat engine using external combustion or virtually any other heat source.
