Desiccant ventilation system is a dehumidification ventilation system used the dehumidification material. If the air eliminated moisture and cooled down is introduced by the desiccant ventilation system, the cooling load can be decreased. In this paper, we present the effect of desiccant ventilation by comparison with the controled total heat exchange ventilation and total heat exchange ventilation. We studied two cooling patterns on four places (Kagoshima, Fukuoka, Tokyo, and Morioka). One is intermittent cooling and the other is all-room cooling during the whole day. In the case of intermittent cooling, cooling load reduction rates are 9.89% on desiccant ventilation, 0.26% on the controled totaled heat exchange venchilation, and -3.36% on total heat exchange venchilation in Kagoshima, 9.11%, 0.24%, and -3.79% in Fukuoka, 10.30%, 0.39%, and -4.28% in Tokyo, and 6.80%, 0.19%, and -16.76% in Morioka. In the case all-room cooling, 17.8%, 4.62%, and 6.43% in Kagoshima, 17.80%, 3.96%, and 6.49% in Fukuoka, 18.47%, 4.62%, and 6.49% in Tokyo, and 12.43%, 1.03%, and -6.98% in Morioka. As the result, cooling load reduction effect of desiccant ventilation is the highest in every places.
