摘要
分析换热器表面的结霜特性 ,及其对换热器性能的影响。从理论上分析几种结霜下的换热器翅片效率公式 ,并对各公式的结果进行比较 。
This paper analyses frosting quality of heat exchanger surface and the effect on performance of it under frosting. Theoretically analyses fin efficiency of heat exchanger surface under frosting condition. From the comparison of some fin efficiency functions,shortages have been pointed out. On the basis of linearization of enthalpy of saturation humid air, a more reasonable fin efficiency function is developed. Analysis result shows that the fin efficiency is independent on air relative humidity in certain temperature range.
