空气源热泵蓄能除霜动态实验台的搭建及研究

Dynamic test-rig structure and research of ASHP energy storage defrosting

摘要:

为解决现有空气源热泵除霜时由于能量来源不足而存在的各种问题,提出空气源热泵蓄能热气除霜的新方法,并对其实验流程进行设计.完成实验台的搭建以及常规热气除霜与蓄能热气除霜的对比实验.结果表明:蓄能热气除霜的实验流程是可行的,可以有效缩短除霜时间150s左右;提高吸气压力180kPa左右;恢复供热的时间也明显缩短;其除霜效果明显优于常规除霜.

Abstract:

In order to solve the problems caused by the lack of energy source in the defrosting process of traditional ASHP,an energy storage based defrosting method for ASHP is presented and the corresponding experimental rig is developed.Experimental results show that the defrosting time can be decreased by 150 s,the suction pressure can be increased about 180 kPa,and the recovering time of heating supply is obviously shortened.It can be concluded that the developed defrosting method and the designed experimental rig are feasible.
