传统四通阀与D-E直通四通阀性能对比分析

Comparative analysis on performance between traditional four-way valve and D-E throughway four-way valve

四通阀是热泵型空调实现供冷和供热切换的核心部件,其性能对热泵型空调性能具有较大的影响。本文介绍一种D-E直通四通阀,并将其与传统四通阀进行测试对比,结果表明,D-E直通四通阀可以提升系统制热性能,但是不会提升热泵型空调系统APF。

The four-way valve is the core component of heat pump air conditioner for cooling and heating,and its performance has a great influence on the performance of the heat pump air conditioner. A kind of D-E throughway four-way valve is introduced,and it＇s compared with the traditional four-way valve by test. The results show that the D-E throughway four-way valve can improve the heating performance of the system,but not the APF of the heat pump air conditioner.
