Abstract

The present invention provides a process and apparatus for utilizing waste heat to power a reconfigurable thermodynamic cycle that can be used to selectively cool or heat an environmentally controlled space, such as a room or a building. The present invention also provides a method of controlling the system, while allowing large variations in the heat input energy rate. The system provides a design which reasonably balances the need to maximize efficiency, while also keeping the design cost effective.
