摘要：家用热泵空调器除霜主要使用逆向除霜和热气旁通除霜，但这两种方式需要停止室内机运行，对供热舒适性有
很大影响。本文提出一种利用制热运行时部分排气漏热进行除霜的蓄热空调系统，充分利用系统余热来实现不间断制
热，改善使用舒适性。通过对蓄热除霜原理及其应用过程中所存在的可靠性问题进行分析，为蓄热除霜技术在家用空
调产品上的推广提供参考。

Abstract：Household heat pump air conditioners mainly use reverse defrosting and hot gas bypass
defrosting, but these two methods need to stop the operation of the indoor unit, which has a great
impact on heating comfort. This article proposes a heat storage air conditioning system that uses part
of the exhaust heat to defrost during heating operation, and makes full use of the system’s waste heat
to achieve uninterrupted heating and improve the comfort of use. By analyzing the pr
