ABSTRACT:
Heat-activated heat-pump systems and related methods are disclosed that include a power cycle coupled to a vapor-compression refrigeration cycle both utilizing the same working fluid. The power cycle comprises a boiler, an expander receiving superheated vapor and producing work from the superheated vapor, a condenser, and a pump. A regenerator conducts a first stream of working fluid from the pump to the boiler and a second stream of the working fluid from the expander to the condenser while transferring heat from the second stream to the first stream. The refrigeration cycle comprises a compressor that compresses the working fluid from the evaporator and delivers the compressed working fluid to a condenser. The expander and compressor are coupled together such that at least a portion of the work produced by the expander is utilized for running the compressor.
