ABSTRACT

This study adopts the wall-mounted solar air collector (WSAC) as a research object, and experimental and theoretical studies were conducted. Specifically, this study proposed a strategy to improve operational efficiency based on the relationships of solar irradiance, supply air flow rate, WSAC transient thermal efficiency, and WSAC net efficiency. Moreover, under the VAV conditions, the building energy consumption was considered. Furthermore, this study analyzed WSAC thermal performance and energy-saving effect in an experimental room under constant, variable, and intermittent air supply volumes. The results show that the VAV air supply mode's net efficiency was more prominent than others considering the WSAC net efficiency. Moreover, compared to the constant air supply mode, the energy-saving rate was 63%. In addition, the best control operation mode was obtained with the changing solar irradiance.
