利用长江水作水源热泵冷热源的探讨
Discuss on using Yangtse River water as heat and cold sources of water source heat pumps
摘要：
对重庆段长江水温进行了实测，在仅考虑制冷剂与冷却水、制冷剂与长江水体之间的传热温差影响的情况下，水源热泵机组的性能系数能达到6.4以上，热力完善度大于0.76，认为利用长江水作为水源热泵机组的冷热源具有极大的节能潜力。

Abstract Measures the water temperature of Yangtse River in Chongqing reach. When only considering the effects of heat transfer temperature difference between refrigerant and cooling water and that between refrigerant and the river water, the coefficient of performance of water source heat pump can achieve to over 6.4 and the thermal perfect efficiency can achieve to over 0.76.Therefore, the use of Yangtse River water as the heat and cold sources of water source heat pumps will have great potential of energy efficiency.
