直接蒸发冷却空调机性能研究

Study on the Characteristics of Direct Evaporative cooling Air Conditioner

分析了影响直接蒸发冷却空调机性能的因素 ,然后对天然植物纤维填料式直接蒸发冷却空调机性能进行了实验研究 ,并获得了相关性能曲线。研究结果表明 ,直接蒸发冷却空调机在我国西北干旱和半干旱地区降温加湿效果很好 ,完全可以达到舒适性要求 ,是一种节能的绿色空调 ;天然植物纤维填料阻力较大 ,但降温加湿效果更好。

Factors that influence the Characteristics of direct evaporative cooling air conditioner is analyzed theoretically at first,then a natural plant fiber filler Direct Evaporative cooling air conditioner is studied experimentally in the paper,and some performance curves are obtained.The study results show that direct evaporative cooling air conditioner can achieve good effect of lowering temperature and increasing humidity of the handled air in the northwest regions of China where the climate are dry or half-dry.And it is a kind of energy-saving green air conditioner.The natural plant fiber filler has larger air resistance but is better for lowering temperature and increasing humidity.
