The objective of this series of investigations is to develop compact heat pumps which exhibit sufficient heat output performance and high COP at temperatures below-10℃. For heat pumps which absorb heat from atmosphere, a crucial problem arises when it is used in cold regions since their heat output decreases with the decrease of outdoor temperature. This study presents characteristics of the actual performance of a gas-engine heat pump when it is used in a cold region. It shows changes in COP, PER, and heat output power for different temperature conditions, as well as the extent of deteriorated PER due to defrost operation, and determines the amount of heat recovered from the engine. Based on the analysis, we propose a system conbined with a heat storage tank, which will improve power output performance while maintaining high COP in cold outdoor conditions.
