The use of a novel thermodynamic cycle combined with a high efficiency expander and compressor provides a unique product opportunity for residential, commercial and industrial Combined Cooling, Heating and Power (CCHP) applications. The cycle can be described as a combination between a Stirling Cycle and an Otto Cycle with isothermal compression followed by constant volume heat addition then by isentropic expansion with the final process being heat addition or heat reject in either a constant volume or constant pressure process. The cycle can be run in an open cycle or a closed cycle with the closed cycle providing a more compact device for a given capacity while the open cycle provides an opportunity to get rid of one of the heat exchangers and cool or heat the air directly.
