摘要

微通道换热器的应用日益普遍。文章通过将微通道换热器引入3 HP柜式家用空调，并对系统性能和充注量等进行了对比研究。实验表明：当只更换室内换热器，室内微通道换热器翅片间距为1.4 mm时，系统性能达到最优：与原机相比，系统充注量降低15.9%，制冷量基本相当，制冷COP提高2.2%；制热量比原机提高3.9%，制热COP则提高了11.2%。当将室内外换热器都更换为微通道换热器后，系统的充注量降低54%，与原机相比：制冷量提高0.8%，系统COP提高5.2%；当制冷剂更换为R290时，系统最优充注量降为500 g。

Abstract

The application of microchannel heat exchanger is becoming more and more widely. The application of microchannel heat exchanger (MCHX) on domestic air conditioning system was investigated experimentally. The results show that: (1) when only the indoor heat exchanger was changed into the microchannel heat exchanger

the system had the best performance when the fin pitch of the indoor MCHX was 1.4mm. The charge of refrigerant for the system reduced 15.9%. Meanwhile

the cooling capacity of the new system was 1% lower than the original system while the COP was 2.2% higher; when it worked in heating mode

the heating capacity of the new system was 3.9% higher than the original one while the COP was 11.2% higher than the original one; (2)when all the heat exchangers were changed into the microchannel heat exchangers

the charge of refrigerant for the system was reduced 54%. Meanwhile

the cooling capacity of the new system was 0.8% higher while the COP was 5.2% higher than the original one in refrigerating mode; when the refrigerant was changed into R290

the best refrigerant charge for the new system was 500 g.
