A two-capacity residential electric heat pump utilizing a unique dual-stroke compressor has been developed, designed, constructed in preprototypic form and laboratory tested. The estimated annual energy efficiency of this system is twenty percent better than a presently available two-speed electric heat pump. A computer based constrained optimization procedure was used to select heat exchanger proportions, air flow rates and compressor stroke ratio in order to minimize the annual ownership cost subject to comfort constraints upon delivered air temperature and dehumidification. A high-efficiency dual-stroke compressor, indoor blower and outdoor fan plus a microprocessor based control system were specifically developed for this system. This paper highlights the hardware development and summarizes system and component performance.
