Abstract
The climate of summer in Korea is quite hot and humid. Many studies have been carried out to reduce the energy required for operating a dehumidifier. The dehumidifier is mainly connected to the cooling system since it operates in the summer. Conventional dehumidification methods often require additional cooling and energy for dehumidification. In this study, a system for increasing the efficiency by applying a membrane was analyzed. Its energy saving effect was analyzed when it was applied to residential buildings. Economic efficiency was also evaluated. As a result of this study, 9.0% energy savings were achieved for residential buildings. The investment recovery period was 28.9 years. Such long investment recovery period was because the initial investment cost was excessive and annual energy saving only appeared in the summer.
