Abstract
This study examined the ventilation performance of solar chimney by the relations of the inlet and outlet, the solar radiation heat-receiving chimney area, the connection conditions of the chimney shaft and chimney. As a result, the ventilation rate was increased in order of 16 m2, 4 m2, 8m2 chimney horizontal cross sections. And when the section area was same, the increase of the solar radiation heat-receiving chimney area was effective than chimney height. A chimney shaft was narrower than a chimney was effective in the case of 16 a chimney cross section area. However, a chimney shaft was wider than a chimney was effective in the case of 4 m2 a chimney horizontal cross section area. And the ventilation rate was not increased that much when the section area rate of the outlet for the inlet were more than 2.
