홈페이지논문 초록 (Abstract)
Most researches done on heat pumps have been on heat pumps for refrigeration, cooling and heating. There is therefore the nee d for more research on hot water heat pumps, especially for high tem perature. Even though the cascade heat pump cycle has a great potential more efficient hot water generation even at low evaporating temper atures, it has been researched leastfor this purpose. In this study, th e heating performance of a variable speed cascade heat pump was investi gated by varying operating conditions. For the same heating capacity v alues, it was found that increasing the low stage compressor speed was more suitable for enhancing the performance of the system to get a higher temperature.
