空调机组蒸发器干、湿工况临界状态的特性研究
|
摘要
本文对不同工况下空调机组中蒸发器干、湿工况及其转变规律进行了研究,提出了"干湿临界工况"的概念,得到了干湿临界工况数值组。研究结论为蒸发器干、湿工况提供判定依据,并为空调机组性能预测及节能运行提供参考。
This paper studied the evaporator dry and wet conditions of air conditioning and its transformation rules under different conditions. The concept of "wet and dry critical conditions"was put forward and the numerical group of wet and dry critical conditions was calculated. The conclusion provides the basis for the judge of evaporator dry, wet conditions and provides a reference for the performance prediction and energy saving operation of air conditioning units.
