Abstract :
Water quality and temperature have important influences on energy efficiency of Lakes Water Source Heat Pump (LWSHP) systems. The characteristics of lake, especial spatial and temporal distribution features, must be obtained in order to take high quality water. By one year´ s monitoring for quality and temperature of Caiyun lake in Chongqing, the results show that average monthly temperature was 26~30°C in summer, 11~15°C in winter. Caiyun Lake water has obvious vertical stratification in summer, while no such phenomenon was found in winter. pH value, turbidity and chlorophyll a also have obvious characteristics in vertical distribution, while hardness and salinity have little characteristics. Lakes water in Chongqing is a hot and cold water source of Water Source Heat Pump (WSHP) of high quality. Water intake head should be installed in the middle and lower layer of the lake, the main problem of water quality is to remove algae and scale inhibition.
