The determination method of limit energy consumption of water supply in open-loop surface water source heatpump systems

WANG Yong1a,HAN Chuan-pu1a,LI Wen2,FAN Wei1b(1a.Key Laboratory of the Three Gorges Reservoir Region's Eco-Environment,Ministry of Education; 1b.College of Materials Science and Engineering,Chongqing University,Chongqing 40044,P.R.China; 2.Ningbo University Architecture Design Institute,Ningbo,Zhejiang 315021,P.R.China)  
For the open-loop surface water source heat pump systems,energy consumption of water supply is the key factor for energy saving of system.On the basis of energy consumption model of heat pump unit and energy consumption model of water supply etc.,open-loop surface water source heat pump system energy efficiency ratio coupling model is established.Based on energy efficiency ratio,the coupling limit value of surface water source heat pump system in different temperature of water supply and different energy consumption of water supply is obtained.Through the actual case,energy saving rate of the system is calculated in different temperatures of water supply and different system modes.And the determination method of the limit energy consumption of water supply of open-loop surface water source heatpump systems is established.
