Abstract: Solar energy technology has good potential for heat generation of residential space heating and domestic hot water production. It has been reported that solar energy entering the roof of a typical home exceeds energy consumption per year. A liquid type is widely used as a medium to convert solar energy entering the roof into thermal energy. However, an air is the ultimate receiver of energy, and there is no problem of leakage, and it can be used by ventilation. By these reasons, in this study, air-based solar heat collection system is examined. In this research, an annual simulation was conducted to grasp the performance of air-based solar heat collecting system. It was prepared with reference to the past research of the solar thermal system simulation model. In addition, the accuracy of the simulation model was examined by comparison with the experimental results, and the validity of the simulation was confirmed.

Keywords: Solar heating system, validation, simulation, heat balance
