Ventilation impact of a solar chimney on indoor temperature fluctuation and air change in a school building

摘要

The aim of this research was to investigate, experimentally, both the feasibility of a solar chimney to reduce heat gain in a house by inducing natural ventialtion and the effect of openings (door, window and inlet of solar chimney) on the ventilation rate. The study was conducted using a single-room shcool house of aproximately 25 m~3 volume. The southern wall was composed of three different solar chimney configurations of 2 m~2 each, whereas, the roof southern side inclluded two similar units of 1.5 m~2 each of another solar chimney configuration. Those configurations were built by using common construction materials.
