Effect of evaporative cooling technology on indoor particulate matter concentration

 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.
