摘要
通过对现有热泵系统的分析,提出了一种新的热泵室外机系统。该系统以盐水为冷媒,采用二级换热结构,可以有效防止冬季供暖过程中室外机的结霜。
Through the analysis on existing heat pump systems, proposes a new heat pump outdoor unit system. This system uses the brine as cooling medium and adopts the structure of two stage heat exchange, and it can effectively avoid frosting on the outdoor unit during the heating in winter.
