摘　　要：针对以重庆市为代表的山地城市,其大落差造成取水能耗过高的特点,提出以水轮机-水泵取水为主要研究对象的能量回收型水源热泵系统.从水源条件和技术经济角度探讨了水轮机-水泵取水系统的可行性.将水轮机-水泵应用于重庆新天地江水源热泵工程进行分析,结果表明每年可回收排水重力势能36.31万KWh,节能率达到20.8%.可依据水轮机-水泵和变频泵的性能曲线,建立输配系统运行的控制策略,达到节能降耗、高效环保的目的.As in mountain topographical cities as Chongqing,the energy consumption of intake-water exceeds the designed standards of water-source heat pump system,owing to the large elevation difference between the drainage pool and the river level.This article presented a new water-source heat pump system with hydroturbine-pump as the main research object.The feasibility of hydroturbine-pump water-intake system on the basis of the water resources condition and techno-economy was discussed.Theoretically,this system has application in a water-source heat pump system project in Chongqing,and the application shows that the new energy consumption system saves gravitational potential energy at 3.631 million kWh per year,compared with the conventional HVAC system,the energy saving ratio is up to 20.8%.Through fitting the performance curve of hydroturbine-pump with that of the variable speed pumps,an optimized pump frequency control method was put forward by adjusting load as well as saving the energy consumption.
