摘　　要：结合涪陵地区某地表水地源热泵工程实例,建立了冷却水泵和热泵机组能耗模型,分析了冷却水进出口温差对冷却水泵及热泵机组性能的影响,得出系统总能耗最小时的冷却水最佳进出口温差为8.1℃,相应的节能率为4.5%～6.5%。With an engineering example in Fuling, establishes the energy consumption models of cooling water pumps and heat pump units, analyses the influence of cooling water temperature difference between the inlet and outlet on the cooling water pump and heat pump unit, obtains 8.1℃ as the optimal cooling water temperature difference between the inlet and outlet with the minimum total energy consumption, and the correspondent energy saving rate is 4.5- 6.5 percent.
