Sizing Method and Seasonal Performance of Passive Solar Chamber System

This study focused on the application of the Passive Solar Chamber System (PSCS) as proposed by a previous study. The seasonal performance and sizing method for the system were investigated for a feasibility of the PSCS in Korean climate. For seasonal performance, heat and ventilation performances of the PSCS were analyzed for the months of January and August. This study proposed a simple configuration method in which the designer can decide on the system size at the preliminary design stage by using system efficiency, overall heat transfer coefficient transmission, monthly solar radiation, highest and lowest temperatures. During weeks that require heating, the system showed to acquire a daily average heat amount of day. For cooling periods, the system was computed to supply a daily average natural ventilation of to the room. Moreover, proposed sizing method and the overall computation results showed a 6.04~7.24% error of assessment.
