风冷热泵型家用空调器除霜、除冰控制方法研究

Study on Defrosting and Defreezing Control Methods of Fan-cooled Heat Pump

对风冷热泵型家用空调器在低温制热过程中结霜、结冰的原因进行了分析,提出几种常用的除霜、除冰的控制方法,结合空调器的实际运行情况提出一种典型的除霜、除冰控制方法。

The paper analyzed the reasons of frosting and freezing under low-temperature heating process for fan-cooled heat pump,and got the common control method of defrosting and defreezing. Verifying it with the test data and combining the actual running conditions to get a typical control flow of defrosting and defreezing.
