摘要(Abstract):

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.
