Research On Multiple Source High Temperature Heat Pump System Based On Wind Power

Heat pump which can replace heating boiler and improve the efficiency of energy utilization is a new technology.It is an effective means to reduce abandoned wind power.Wind energy heat pump can improve power consumptive capacity and make wind power accounting promote.That is of important significance for adjusting energy structure and controlling emission of greenhouse gases.First,this research mainly put forward multiple source two stage compression high temperature pump system driven by wind power which fitted for cold region and was based on deficiency of current multiple sources heat pump.And multiple source high temperature pump system model was established.Then,it had been successfully developed of prototype of multiple source high temperature pump of 30 k W heating capacity which was based on multiple source high temperature pump system model.Experimental platform of air-ground multiple sources wind energy heat pump was set up and tested.The test results showed that heat pump system outlet temperature could reach up to 65? and performance coefficient could reach up to 2.5.Heating capacity had a considerable fluctuation with output of wind turbine.Heat storage tank played an important role in stabilizing output heat.Based on thermodynamics laws,air-source heat pump,soil-source heat pump and multiple source heat pump were compared with each other finally.The exergy balance model of multiple source heat pump was established,and the exergy losses were analyzed.The main innovative points are thermodynamic analysis and studying of operation performance of multiple source wind energy heat pump system.And the research results can provide theoretical foundation for the wind energy heat pump heating.
