摘要
对于开式地表水源热泵,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水源热泵系统的能效耦合模型。基于节能率及水泵能耗的规律特点计算得到了不同的冷却塔出水温度下,不同水泵扬程下的动态取水温度限值,建立了开式地表水水源热泵动态取水温度限值的计算方法。并计算得到不同工况条件下的地表水源热泵系统相对传统空调的节能率。
Energy consumption of water intake is one of the key factors for energy saving in the application of the open-loop surface water heat pump system. An energy efficiency ratio coupling model for open-loop surface water source heat pump systems was established on the basis of the energy consumption model for the water intake and the heat pump units. According to energy saving rate and regulation of energy consumption of water intake, dynamic temperature limits of water intake in different water supply temperature of cooling tower and different pump head were proposed so as to find a calculation method of temperature limits of water intake of open-loop surface water heat pumps. Moreover, the energy saving rate of surface water source heat pump systems compared with traditional air-conditioning systems under various condition was also calculated.
