Paper Title:
Analysis of the Water Intake Technology of Open-Lakes Water Source Heat Pump System in Chongqing
  Abstract

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.
