The maximum installed capacity mathematic model has been set up and analysis about surface water source heat pump using at large scale. The maximum installed capacity of Nu River China has been calculated by the equations as an example. In the mean time, the key coefficients have been simplified while practical application in engineering. A general conclusion of the maximum water source heat pump installed capacity has obtained for different surface water characteristic. The value from the general conclusion can use in the plan and the layout on the surface water source heat pump system large-scale use. That will protect ecological environment and against creates the destruction.

To comprehensively evaluate surface water source heat pump system, the problem of water heat pollution of thermal discharge in surface water source heat pump system should be seriously considered. This study summarizes the causes and hazards of water heat pollution of surface water source heat pump, explores the characteristics of water heat pollution of lake-source heat pump system, river-source heat pump system and sea-source heat pump system respectively, and proposes several preventive measures for solving the problem. Concludes that surface water heat pumps discharges can change local water temperature, and various types of water bodies have different degree of heat pollution.

Lakes And Reservoirs

To research the suitable water intake technology of open-lakes Water Source Heat Pump system (WSHPs) in Chongqing, water temperature, water quality and other water features of lake and reservoir are analyzed. Results show that the temperature of water source in Chongqing’s lakes and reservoirs excelled the air temperature, and the water quality basically meets the requirements of open-lakes WSHPs. Thus the water source in Chongqing’s lakes and reservoirs is a hot and cold source of good quality. For depth of water is greater than 6m, there is an obvious vertical stratification of water temperature in summer, which is not obvious in winter. pH value, turbidity and algal density also have obvious characteristics in vertical distribution, while hardness and salinity have little characteristics. According to the spatial and temporal distribution features of water temperature and water quality, water intake head should be installed in the middle and lower layer of the lake. Less investment and water head loss, lower operation and maintenance costs, and higher reliability should be considered when we choose the way of water intake for WSHPs in Chongqing. Water intake ways such as pump truck water intake, pontoon intake, gravity pipe intake, integrated device are alternative. Comparison between technical and economic should be made first.

Influence Of Water

Water source heat pump system(WSHPS) is a new energy saving and environmentally air conditioning system, its degree of influence to groundwater related to the feasibility of construction of WSHPS and development & protection of regional groundwater. After introducing WSHPS, this paper analyzed the influence of WSHPS to groundwater, brought up the protection method to reduce influence. At last, a case study of new campus of Taiyuan university was carried out. The results showed that running of WSHPS won’t bring up disadvantage to groundwater environment.
