摘　　要：为了减少热泵系统运行的有效能损失,提高能量利用的完善度,在满足系统供冷、供热的可靠运行条件下,建立了水源热泵空调系统的压缩机、冷凝器、电子膨胀阀、蒸发器、冷凝器侧的水泵及蒸发器侧的水泵的损失数学模型,以总损失(热泵机组和水泵损失)最小为目标函数,对水-水热泵系统进行运行优化,得出相应的运行参数范围。To reduce the loss of exergy in running process of heat pump system and improve the efficiency of exergy, a series of mathematical models of exergy loss of compressor, condenser, electronic expansion valve, evaporator, water pumps on both sides of condenser and evaporator of the water source heat pump system were put forward, and an optimization of water-water heating pump system which with the minimum value of exergy loss as optimization objective was carried, and the optimization parameter values for the water-water heating pump running reliably were acquired.
