摘　　要：热泵空调器在低温状况下制热能力下降得很快,有时候甚至不能制热。制热运行是一个逆卡诺循环过程,可以分为四个环节,要改善制热衰减问题,可以从这四个环节进行研究。在前人研究的基础上,通过建立数学模型并结合实验验证,总结出改善低温制热效果的几种措施。Heat pump air conditioners heating ability at low temperature conditions reduced too quickly,and sometimes not even heating.Heating operation is a reverse Carnot cycle,it can be divided into four areas,you can study from the four areas to improve the system of thermal decay problem.The author,based on previous research,a mathematical model by combining with experiments,summarized several measures to improve low-temperature heating effect.
