Research on Heating Performance of Combined Solar and Air Source Heat Pump System
The combination of solar photovoltaic system and air source heat pump system can make full use of the two low-grade heat sources,solar energy and air energy,to achieve the complementary advantages of the two.The heating performance of the system under the coupled operation of solar energy and air source heat pump is analysed through simulation.Comparative analysis of the three operation strategies of all-day solar heating,all-day single air source heat pump heating,and solar and air source heat pump coupled operation yields that compared with the single air source heat pump,the power consumption of the solar-assisted air source heat pump is reduced by 925.85 W,a reduction of 2.17％.The average COP of the air source heat pump in this mode was 3.96,an improvement of 1.7％.The average COP of solar-assisted air source heat pump is improved by 22.29％during the frost period of air source heat pump.The simulation study of this coupled system is carried out with a view to providing a reference for multi-operating condition operation for the subsequent construction of the experimental bench of multi-energy complementarity and the application of farm houses and office buildings.
