摘　　要：为了解决多联机空气源热泵常规除霜时间长、室内环境恶化等问题,提出多联机热泵相变蓄能除霜方法。针对提出的新方法,设计系统流程和试验方案,并在模拟室内外环境条件下完成试验研究。相对于常规除霜,新的除霜方法可以有效缩短33.7%的除霜时间,显著改善机组的除霜性能和室内供热环境。A defrosting method of multi-split air-source heat pump using phase change material is provided to solve the common issues of long defrosting duration,indoor environment deterioration,etc.According to this new defrosting method,the system process and testing program are designed.And the experimental study is conducted under simulated indoor and outdoor environment.Compared to the traditional defrosting method,when using the novel method,the defrosting duration can be shorted by 33.7%,and defrosting performances and indoor environment can also be improved evidently.
