摘　　要：空气源热泵空调系统在低温高湿工况下制热运行时除霜频繁,且除霜期间无法持续供热,室内热舒适性差。提出了一种新型外加热源辅助制热空气源热泵系统,实测结果表明:室外侧进风干/湿球温度-7℃/-8℃工况下,制热运行时间长达594 min,较常规系统延长195%,且化霜期间仍能提供不低于38℃的出风,舒适性体验得到较大改善。Air-source heat pump frequently defrosts at the condition of low temperature and high humidity,and cannot continue heating during defrosting,which resulting in poor indoor thermal comfort.Presents a novel air-source heat pump system with external heat source auxiliary heating.The experimental results show that at the operating condition of-7℃/-8℃ of outside wet and dry bulb temperature,the continual heating operation time is up to 594 min,195%longer than that of the conventional system,and the supply air with temperature no lower than 38 C is still provided during the defrosting,which greatly improves the comfort experience.
