摘要
结合湿空气焓湿图,分析了在非干燥地区蒸发冷却与机械复合全年运行空调系统中蒸发冷却"免费供冷"的应用条件,并定量计算出了其免费供冷的潜力。得出了在过渡季节,机械制冷段不开启的情况下,通过蒸发冷却处理可完全满足室内空调要求,节能效果达80%以上;在夏季炎热季节可减少机械制冷负荷26%,极大提高了空调系统能效比,节约了系统能耗。
The application condition of evaporative cooling assist to mechanical refrigeration system was analyzed combined with the weather data and wet air psychrometric chart, And a quantitative calculation of the potential of its free cooling is brought for-ward. It is obtained that during the transitional season, in the case of Mechanical refrigeration does not open, through evaporative cooling treatment can fully meet the requirements of indoor air-conditioning, 30% energy could be saved at least, in the hot summer season 26 % cooling load saved, improved EER air-conditioning system greatly, and energy consumption reduced.
