| Summary: | This paper presents the investigation of solar induced ventilation that utilizes roof solar
collector and vertical stack. Three prototypes, namely A, B and C, were developed based
on preliminary experimental work. They were then used in simulation study with the
objective of determining the prototype that was able to induce the highest mass flow
rate. The validation of simulation modelling against experiment indicated a good
agreement between these two results. The findings showed that prototype A induced the
highest mass flow rate. However, prototype C, which had obstructions at the stack
outlets, was more appropriate for application in Malaysia due to various prevailing
wind directions. In addition, the findings also indicated that besides solar radiation,
the mass flow rate induced by the prototypes was also influenced by the local wind
direction, the inlet and outlet positions as well as the outlet design. In summary, the
findings highlighted the potential application of the proposed solar induced ventilation
in a hot and humid climate. |
