摘要: Abstract Air source heat pump (ASHP) is a sustainable and efficient technology for space heating, which has been widely used over the recent decades. In order to improve thermal efficiency of ASHP heating system, novel storage refrigerant-heated radiator coupled with system proposed. this high temperature refrigerant steam discharged from compressor sent directly through radiation natural convection. Energy water injected supply energy during defrosting process. A set experiments have conducted in climate chamber study performance system. The results show that less dissipation uniform surface temperature. As performances, coefficient varies 4.4 3.3 as condensing increases 35.9 °C 44.0 °C, it 4.2 1.8 outdoor air decreases 6.9 °C −18.4 °C. also investigated, proving material can maintain comfortable indoor Furthermore, characteristic equation specific given provide reference future application.
