摘要(Abstract):

空气源热泵因其供热效率高而得到广泛应用,但是室外换热器的结霜问题导致了其供热效率的下降。针对空气源热泵室外换热器单管的融霜过程,搭建了单翅片管融霜实验台,使该单根翅片管分别以结霜和融霜2种模式运行。融霜过程分别选择40,30,20,10,5℃的循环溶液,同时对融霜过程进行理论分析。试验以及理论分析结果表明:在不同的循环溶液温度下,随着循环溶液温度的升高,融霜速率逐渐增加且变化趋势加快;循环溶液温度的高低对融霜过程产生程度不同的影响,存在最佳循环溶液温度,可以使得除霜效率达到最高。
Air source heat pump has a very wide range of applications,but the frost accumulation of outdoor heat exchanger in winter restricts the use of it. For the defrosting process of single-tube of air source heat pump outdoor heat exchanger,an experiment table is built. The single tube is transformed into the frosting and defrosting model respectively by controlling the switch of the three-way valve. In defrosting process,the temperature of circulating solution is changed to 40℃ 、30℃ 、20℃,10℃ 、5℃,at the same time,theoretical analysis is carried out for the defrosting process. The experiment results and theoretical analysis show that the higher the temperature of the circulating solution,the better the defrosting rate; the temperature of the circulating solution has effect on the defrosting process,and the defrosting efficiency is highest at the best circulating solution temperature.
