Effect of evaporative cooling technology on indoor particulate matter concentration
摘要：
对冬季雾霾天和夏季高温天气利用蒸发式冷风扇及窗式蒸发冷却空调器进行了实验，分析了直接蒸发冷却通风空调技术对室内颗粒物浓度的影响；对比了2种不同条件下室内颗粒物的净化效率，得出夏季选用窗式蒸发冷却空调器与通风结合，对室内PM2.5净化效率为52.1%，对PM10净化效率为62.9%，对TSP净化效率为72%的结论；提出了一种与蒸发冷却技术相结合的空调方案。
Abstract：
Tests evaporative cooling fans and window evaporative cooling air conditioners in winter smog days and in summer high temperature weather, respectively. Analyses the effect of direct evaporative cooling ventilation and air conditioning technology on indoor particulate matter concentration. Comparing the purification efficiency of indoor particulate matter under two different conditions, concludes that in summer, window evaporative cooling air conditioner combined with ventilation can achieve 52.1% purification efficiency of indoor PM2.5, 62.9% purification efficiency of PM10 and 72% purification efficiency of TSP. Puts forward an air conditioning scheme combining evaporative cooling technology.
