摘要

分别配置了采用传统铜管铝翅片换热器与采用全铝微通道换热器的1.5匹分体式家用空调，将其置于相同的大气环境中长期连续运行，测试了大气颗粒物污染的两台家用空调换热器的堵塞率和空调系统的长效性能。测试结果表明：换热器的堵塞率呈指数性增长趋势，采用管片式换热器的原机被大气颗粒物污染后制冷量衰减2.1%，功耗上升了6.2%，能效比下降了7.8%；采用微通道换热器的机组性能衰减明显高于原机，制冷量衰减了23.2%，功耗增加了34.6%，能效衰减了43.1%。相比之下微通道换热器更易受颗粒物污染的影响。

Abstract

This paper focused on the impact of outdoor heat exchanger polluted by atmospheric particulates on the system performance with the study object of 1.5 HP residential split-type air conditioner

and the fouling processes of copper tube-aluminum fin and aluminous microchannel heat exchangers were compared. Two sets of units assembled with different outdoor heat exchangers were continuously running in the same atmospheric environment. Capacity

power consumption

discharge temperature

condensing temperature and plugging ratio were tested to analyze the influence of atmospheric particulate pollution on the long-time performance. The results show that the plugging ratio of outdoor heat exchangers grows exponentially

the refrigerating capacity of the air conditioners assembled with cooper tube-aluminum fin and aluminous microchannel heat exchangers is decreased by 2.1% and 23.2%

power consumption is jumped by 6.2% and 34.6% and COP is decreased by 7.8% and 43.1%. Research problems and direction of long-term performance of aluminous microchannel heat exchangers in air conditioners are pointed out．
