微通道换热器结霜性能的试验研究
Experimental Research on Frost Performance of MicroChannel Heat Exchanger
摘要
Abstract
Frost performance of the micro channel heat exchanger (MCHE) was experimentally investigated according to the dew temperature of moisture air and medium temperature.The results show that,in the dew conditions,the changes of pressure loss and the heat transfer capacity are not obvious,the change values are 11 Pa and 27 W respectively,and water drains out only from the reversed surface of the MCHE.In the dew and frost conditions,the changes of pressure loss and the heat transfer capacity are not obvious,the change values are 68 Pa and 20 W respectively,dew is occurred first,and then frost,the frost on the MCHE surface faced air is smaller than that reversed air.In the sublimation conditions,the changes of pressure loss (the value is 533 Pa) and the heat transfer capacity (the value is 300 W) are obvious,sublimation is occurred,the frost on the MCHE surface faced air is very smaller than that reversed air,and the MCHE is seriously blocked for one hour experiment later.关键词
