Design of district cooling and heating system with river-water-source heat pump for Jiangbeicheng area in Chongqing

Presents the energy station system design of the central cooling and heating project adopting river-water-source heat pump for the Jiangbeicheng central business district(CBD) in Chongqing. Calculates the air conditioning cooling and heating load of the energy station, and elaborates the layout of the machine room, the automatic control design, the ice tank method and its influence on the water environment. The project combines ice cool storage with heat pump system to realize district central cooling and heating, and adopts direct river water cooling technology. The evaluation results show that, comparing with the traditional cooling and heating system, the system saves 9.933 million yuan in summer and 9.094 million yuan in winter, with a good economy.
