摘　　要：对于开式地表水源热泵来说,取水能耗是决定系统节能性的关键因素。在水源热泵机组能耗模型、取水能耗模型等的基础上建立了开式地表水源热泵系统的能效比耦合模型,并得到了基于节能率的地表水源热泵系统的不同取水温度和不同取水能耗下的耦合限值。通过实际案例,计算得到了地表水源热泵系统不同取水温度下以及不同系统方式下的系统节能率,建立了开式地表水源热泵系统取水能耗限值方法。For the open-loop surface water source heat pump systems,energy consumption of water supply is the key factor for energy saving of system.On the basis of energy consumption model of heat pump unit and energy consumption model of water supply etc.,open-loop surface water source heat pump system energy efficiency ratio coupling model is established.Based on energy efficiency ratio,the coupling limit value of surface water source heat pump system in different temperature of water supply and different energy consumption of water supply is obtained.Through the actual case,energy saving rate of the system is calculated in different temperatures of water supply and different system modes.And the determination method of the limit energy consumption of water supply of open-loop surface water source heatpump systems is established.
