초록

The purpose of this study was to investigate the air flow characteristics of the rock bed storage for solar-heated greenhouse design. Heat storage material was gravels and experiments were performed under constant inside temperature condition. The experimental parameters were operation method and air flow rate of fan. It was resulted that the temperature and amount of heat stored in rock-bed increased as the increase of air flow velocity and were more influenced by operation of inlet fan than outlet fan.
