摘要
热气旁通除霜技术应用于变频热泵空调机时对低温制热量、舒适性都有显著改善。本文详细介绍了热气旁通除霜技术在变频热泵机型上的应用方法,强调了旁通量的控制,介绍了如何通过结霜拐点确定最佳除霜切入时间以及除霜过程的最佳控制方式。
The hot gas bypass defrosting technology applied to the variable frequency heat pump air conditioner on the low temperature heating,comfort has improved significantly.This article describes in detail the hot gas bypass defrost technology in the frequency conversion heat pump on the application of the method,stressed that the amount of the bypass control,describes how to determine the best defrost entry time by determining the inflection point,and the best way to control the defrosting process.
