　　本文对一种新型微通道换热器在家用空调中的应用进行了实验研究。对于相同的迎风面积，新型样件的内容积比传统微通道换热器降低了71%，系统充注量可降低28．3%，且系统性能基本保持不变。通过估算，若此新型微通道换热器用于R290空调系统，并结合压缩机小型化和润滑油改进，有望将R290系统充注量降低到150g左右，可以满足欧盟IEC标准，使该状态下的R290空调达到无限制使用的安全标准。

The experimental study of a novel microchannel heat exchanger in domestic air conditioner was conducted. For the same frontal area, the inside volume of the new microchannel sample decreased by 71%compared to the conventional sample. The amount of the refrigerant charge decreased by 28. 3%, and the sys-tem performance had no obvious change. It is estimated that if this new micro-channel heat exchanger is used for R290 air conditioning system, refrigerant charge amount will be reduced to 200g and it will meet the R290 safe use standard.
