变片距蒸发器性能数值分析与实验研究

Numerical Analysis and Experimental Study on Performance of Evaporator with Combination of Different Fin Pitch

论述了结霜对蒸发器运行性能的影响,分析了变肋片间距蒸发器在低温结霜工况下的性能。提出了运用于变片距蒸发器的设计的数值计算模型,通过实验值与数值计算值的对比证明了此计算方法的可行性。

The characteristic of evaporator working in the frosting conditions was discussed in this paper. In order to avoid the detriment effect of accumulation of frost on the performance of coil, the evaporator with combination of different fin pitch was suggested and mathematic model suitable to calculate this particular evaporator was also put forward. By comparing date coming from experiment and calculation, this method is feasible.
