摘　　要：现有热泵空调器在制热除霜过程中,不仅不向室内房间提供热量,还会吸收房间的热量用于除霜,降低热泵空调器制热舒适性。基于此痛点问题,本文提出一种可实现持续制热的除霜技术,从原理上分析了方案的可行性;并对该方案开展试验研究。试验结果表明,采用这种除霜技术的空调器能在保证化霜效果的前提下,有效提高制热舒适性。In the process of defrosting,the existing heat pump air conditioner not only does not provide heat to the indoor room,but also absorbs the heat of the room for defrosting,reducing the thermal comfort of the heat pump air conditioner.Based on this problem,a defrosting techniques which can realize continuous heating are proposed in this paper,and the feasibility of the scheme is analyzed in principle.The experimental research is carried out on the scheme.The experimental results shows that the air conditioner using this defrosting scheme could effectively improve the heating comfort under the premise of guaranteeing the effect of the frost.
