Analysis of Pollutant Concentrations in Air-condition Room with Different Types of Air Supply

Abstract In order to improve the air quality of the offices with pollutant and reduce the concentrations of it to satisfy the demand of workers for health. This paper simulated three different types of air supply, three different air volume and three different concentrations of pollutant and obtained indoor pollutant concentrations under different ways and different air pollutant emission power. The comparison of results show that the air supply of up-inlet and down-outlet on the same side have a better decontamination effect than other two types of air supplies. Increasing the quantity of fresh air can significantly reduce the concentrations of indoor pollutants, so does reducing pollutant emmision power. Results indicate that if we want to control the indoor pollutant concentrations, the methods of up-inlet and down-outlet on the same side should be adopted, which could increase the volume of fresh air and reduce the concentrations of the pollutant.
