摘　　要：基于“双碳”目标,我国各领域电能替代工作取得了蓬勃发展。在建筑领域,目前我国正在大力推广空气源热泵供暖技术,为了探究其电力替代可行性,基于空气源热泵结霜机理,提出了一种基于气象参数及水相图的结霜理论判断方法,并选取夏热冬冷地区10个典型城市进行了空气源热泵供暖结霜规律分析。结果表明,夏热冬冷地区整体较适合开展空气源热泵供暖,但工程实践中应结合不同城市结霜规律针对性制定除霜控制策略。此外,提出的空气源热泵结霜判断方法相较于传统研究具有一定优势,可有效避免热泵机组结霜时长被低估等问题。该理论方法为解决夏热冬冷地区“双碳”目标与健康舒适人居所面临的挑战提供了有力支撑。Based on the goal of"dual-carbon",China's electric energy substitution work in various fields has achieved vigorous development.In the field of construction,China is now vigorously promoting air source heat pump heating technology,in order to explore the feasibility of electricity substitution,this study is based on the frost mechanism of air source heat pump,puts forward a theoretical judgment method of frost based on meteorological parameters and hydrographs,and selected 10 typical cities in hot summer and cold winter areas for the analysis of the frost pattern of air source heat pump heating.The results show that the hot summer and cold winter areas are more suitable for air source heat pump heating,but the engineering practice should be combined with the frost law of different cities to develop a targeted defrost control strategy.In addition,the air source heat pump frost judgment method proposed in this study has certain advantages compared with traditional research,which can effectively avoid problems such as the underestimation of the frost duration of the heat pump unit. This theoretical approach provides a strong support for solving the challenges of "double carbon" target and healthy and comfortable living space in hot summer and cold winter areas.
