| Abstract |
In this study, we have studied a performance evaluation of air handling unit when solar system is applied in large space.stored solar thermal energy from sun to storage tank through solar collectors. Solar thermal energy is sent to heat exchanger and exchange heat with air in heat exchanger. Heated air is supplied to indoor room through air-handling unit. When this system is applied to large space. We confirmed the availability of heating system in large space. And the result shows temperature characteristics of solar system with Air-Handling Unit and the effectiveness of this system experimentally. When only storing solar heat, the temperature of storage tank is raised to 65℃, but, when radiating the solar heat, the temperature of storage tank is raised to 45℃. Finally, the efficiency is about 41-45%, and it is considered the economic benefits have. |
