Research Of Heating Used Photovoltaic(PV) Auxiliary Air Source Heat Pump In Cold Regions

According to the research targets of optimal allocation and energy utilization in building heating system in cold regions,the author will study the joint heating system of PV power generation' auxiliary air source heat pump in building heating planning.In the paper,the author discusses clean energy status and development tendency and summarizes application prospect of solar energy resources and air source heat pump system.Based on the design fundamental theory of domestic and overseas PV power generation'auxiliary air source heat pump,the author uses Dest software to simulate simulation analysis hourly and monthly dynamic load heating in a villa,obtains hourly load in building heating system in a villa,and provides fundamental data for analyzing power consumption of building air source heat pump.By regarding the combination of PV power generation's auxiliary air source heat pump and a villa project as a target,air source heat pump units and systematic automatic control is placed in the PV power generation's air source heat pump system to design.By using Trnsys to do simulation analysis of power consumption in air source heat pump,the author conducts power consumption analysis in heating season and coldest day on villa air source heat pump and obtains the corresponding power consumption data curve.With the precondition of effects generated by solar radiation in climatic conditions in Dalian and based on the climatic parameter variation,the author models,simulates,analyzes and evaluates the entire system operation.The Weatool software is applied to record annual meteorological parameters in Dalian,to obtain environment temperature and direct solar radiation on specific data and monthly average.Based on the data,PVSYST simulation software is applied to obtain corresponding PV power generation on PV simulation analysis and application.Villa projects through the heating season Dalian photovoltaic auxiliary air source heat pump system of economic efficiency analysis of energy saving and environmental protection fuel boiler system with air source heat pump hot water system of four common gas boiler electric boiler hot water preparation scheme comparison,the energy consumption and pollution emission is lower than other systems,is environmental protection,safety,economic heating system,has the very high popularization value.
