Analysis of water source condition for river water source heat pump

The water source condition is one of the key factors affecting the performance and energy efficiency of a water source heat pump. Based on the river water resource condition in Chongqing area, analyses the water characteristics of Yangtse River and Jialing River from four aspects of water quantity, water level，water temperature and water quality, and indicates the application condition and requirements of river water source heat pumps. According to the hydrological data of the Wulong section of Wu River, discusses the feasibility of using river water source heat pump of a project in Chongqing from the water source condition, and analyses the technical measures which guarantee high efficient utilization of water cold and heat resource in design and operation.
