填料-高压微雾复合式两级直接蒸发冷却空调机组的研制

Development of two-stage direct evaporative cooling air-conditioning units combined with filler and high pressure micro fog

介绍核电站常规岛用两级直接蒸发冷却空调机组的优点、工作原理及设计过程,并对实验样机进行测试。实验数据表明,在南通中湿度地区,当室外空气的干湿球温差为4~5℃时,该组合式空调机组对室内空气降4~5℃,使之接近室外空气的湿球温度。指出两级直接蒸发冷却空调机组在核电站常规岛中具有广泛的应用前景。

Describes the advantages,working principle and design process of two-stage direct evaporative cooling air-conditioning units applied into conventional island nuclear power plant and tests the experiment prototype.The experimental data show that the temperature difference is 4～5 ℃ between dry and wet bulb of outdoor air at Nantong,air-conditioning units can make indoor air decrease 4～5 ℃ and make it close to wet bulb temperature of the outdoor air.Points out that two direct evaporative cooling air-conditioning unit has a wide application prospect in conventional island nuclear power plant.
