실거주지에서 토출각에 따른 하이브리드 제습냉방시스템의 열쾌적성 평가

A series of field tests on hybrid desiccant cooling systems were conducted during the summer in 2014. The performance of the cooling system, i.e. cooling capacity and COP (Coefficient of Performance), were evaluated from measured data and its variation subject to outdoor conditions was analyzed. Its performance in a residential environment were proved with typical Korean in connection with existing district heating network. However, economical and functional merits need to be verified to be competitive in commercial market. Thermal comfort is one of the strong points of desiccant cooling system, since it has ventilation and dehumidification functions. To quantify thermal comfort, indices such as PMV and PPD have been evaluated for the air-conditioned space based on measured and CFD data. The results show that supply geometry needs to be improved to eliminate discomfort area.
