Regional Optimum Dedicated Outdoor Air System and Energy Consumption Characteristics
Kim, Hui-Jeong; Yoon, Dong-Seob; Jeong, Jae-Weon;
Building latent loads and sensible loads can be controlled through Dedicated Outdoor Air System (DOAS) which is effective in ventilation as well as humidity control introducing 100% outdoor air into the space. Diverse configurations of DOAS are currently used on the basis of ambient conditions and major target control points. The purpose of this paper is to find the most energy conservative configuration of DOAS when applied in Korea. Considering regional climatic characteristics, 3 DOAS configurations are selected to analyze energy consumption in Seoul, Gangneung and Mokpo. TRNSYS 17 program and commercial equation solver are used for energy simulation according to operation modes of each systems. The conventional DOAS composed of enthalpy wheel and sensible wheel showed highest energy saving effect.
