system efficiency. When system input power consumption is 2 kW, the optimization operation condition parameters are 72 Hz for compressor frequency, 0.4 kg/s for hot water flow rate, 0.5 kg/s for solution flow rate and 1.6kg/s for air flow rate, which leads to the minimum system entransy loss rate, maximum system heat load and maximum system efficiency. Key words: heat source tower heat pump......
