Two-phase compression heat pump cycles have been studied from the theoretical point of cycle analysis to clarify the optimum liquid injection conditions as a first and basic step for developing higher-performance high-temperature heat pump systems, which recover the heat from a 150℃ heat source and supply a 300℃-thermal output. In the case where the working fluid is water, the COP is improved by utilizing a two-phase compressios process and an optimum gas-liquid ratio brings about the maximum value of COP. The two-phase injection cycle, in which the liquid partially extracted from the outlet of the condenser and the gas separated in the economizer are injected into an intermediate point of the compression process, can effectively improve the COP and reduce the discharge superheating.
