Abstract:
Combined the experience of a lake water heat pump project in Nanjing，based on the standard k － ε turbulence model，the temperature field of the thermal discharge into the lake water body was computed． The effect of the thermal diffusion caused by the different locations of the outfall was mainly researched when the lake-depth is uneven． By comparison and analysis，there is a greater influence as to the horizontal distribution than vertical direction，and the high temperature zone concentrates on a small area near the outfall，the short-circuiting can be avoided when the water intake is located on the upstream the outfall，the influence on-environment can be reduced with some measures such as sprinkler system and waterfall． The results provide reference for lake-water heat pump systems design．
