DEVELOPMENT OF FLUCTUATING AIRFLOW GENERATOR FOR THE INDOOR AIRFLOW CAUSED BY CROSS VENTILATION

Abstract

Cross ventilation has the effect on improving the comfort of indoor environment. However, this effect has not been clarified since it is difficult to artificially reproduce the same indoor air-flow as cross ventilation. We have developed a device that is able to generate the fluctuating air-flow of same properties as an air-flow of the cross ventilated room. The verification results of the device’s performance are as follows:
(1)The device that combines a slider and a damper can generate the fluctuating air-flow similar to natural cross ventilation. (2)The properties of the reproduced air-flow virtually correspond to those of natural cross ventilation.
