空气源热泵空调的一种新型除霜控制模式

New Type of Defrost Control Mode for Air-source Heat Pump Air-conditioner System

以实现空气源热泵空调良好的除霜效果为目的,在进行充分试验的基础上,通过采集室外换热器液相冷媒温度和环境温度2个参数,提出了一种新型的除霜进入、除霜方式选择和除霜退出等具体的除霜控制模式,实现了空气源热泵空调机组的智能化除霜。

For achieve prominent defreeze effects in air-cooled hot-pump air-conditioner system,on the basis of sufficient tests, some particular control mode in defreeze model were pointed out, such as entering, mode choosing and quit through the two parameters which collected from out-door evaporators liquid refrigerant and the temperature of the environment, and it was realized intelligentized defreeze model of air-source heat pump air-conditioner system.
