Author(s) : HASEGAWA H., SAIKAWA M., HASHIMOTO K., IWATSUBO T.

Summary

The Central Research Institute of Electric Power Industry (CRIEPI) has independently devised a two-stage compression and cascade heating heat pump cycle for hot water supply. This cycle has a number of advantages over conventional heat pump cycle for hot water supply, including low primary energy consumption and higher hot water supply temperature. CRIEPI is now developing a system for commercial use in hotels and retail stores based on this new technology. The paper presents this new technology.
