Study on Carbon Reduction Performance of Solar Thermal Photovoltaic Coupled Air Source Heat Pump System in Clean Heating
Air-source heat pumps are widely used in clean heating,but the electricity consumed during the operation phase causes a large amount of carbon emissions.Based on the sound energy saving and carbon reduction performance of solar energy,and the need to adapt to the dual control requirements of carbon emissions proposed during the"14th Five-Year Plan"period,this paper studied the carbon reduction performance of solar thermal photovoltaic coupled air source heat pump heating system in clean heating.Taking a typical rural house in Beijing as an example,the model of solar thermal photovoltaic coupled air source heat pump system was established using TRNSYS software,and verified by experiments.Carbon reduction and economic studies on different ratios of collector to photovoltaic array installation area in solar thermal photovoltaic coupled air source heat pump systems are carried out.The results show that the application of solar thermal photovoltaic coupled air source heat pump system in clean heating scenarios has better carbon reduction benefits,improving the carbon reduction energy by 7.2％and 44.8％,respectively compared with only the solar thermal system and photovoltaic system.The payback period can be reduced by 9.9％and 40.1％respectively.
