Modeling water temperature in stratified lake or pond using water source cooling system

摘要

The model of predicting seasonal water temperatures for various loads was presented to determine the cooling capacity of stratified lake or water pond used as heat sinks in southern climates. The model is verified by using data from natural water pond on Chengdu from one year. It is effectively model opened loops located on bottom. Maximum cooling capacity of lake is predicted in case that outlet water is delivered from the bottom and water enters in such a way that temperature of ambient water most closely matches the inlet water temperature. The model is a valuable tool for determining the cooling capacity and performance of lake and pond source cooling system.
