摘要
提出了一种复叠热泵机组,以解决常规空气源热泵冷热水机组在寒冷地区冬季使用压缩比高、效率低等问题。计算结果表明,该机组能在我国北方大部分地区冬季较低的室外环境温度下节能运行。
Puts forward a cascade heat pump unit to solve some application problems of conventional units in winter in cold regions, such as high compression ratio and low heating efficiency, Calculation results show that the unit can operate with higher energy efficiency in winter in most cold regions of north China.
