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.
