一、換氣降溫:由于陽光照射、機器設備發熱等產生的積溫,室外37度,很多車間內溫度高達40度以上,安裝負壓排風扇后能將
車間內熱空氣迅速排出室外,使車間內溫度略低于室外溫度。空氣流動加速汗液蒸發而吸收人體 熱量,從而讓人體感覺涼爽,和自
然風一樣涼爽。
二、水簾降溫:空氣經過水簾,室外37度熱空氣降低為27度的冷空氣,27度的冷空氣在車間內流動,給人十分涼爽的感覺。水的汽化熱為40.8千焦/摩爾,相當于2260千焦/千克。1千卡=4.18千焦,所以1千克水的汽化熱為540.67千卡。1克水的汽化熱為

540.67卡。每蒸發1克水,可以帶收540.67卡熱量.所以水是最清潔,最優良的降溫媒質。
