Abstract
A two-stage air source heat pump having an extended operational temperature range combines intercooling, regeneration, and inter-stage vapor recirculation. Cooling a working gas in between the lower and higher-pressure stages decreases the work required to compress the working gas. The entire system may be computer controlled using sensors to monitor flows, temperatures, and pressures in and around the system.
