| description |
Stack ventilation in the hot and humid climate is inherently inefficient due to minimal air temperature
differences between indoor and outdoor environment of a naturally ventilated building. Solar induced
ventilation is a viable alternative in enhancing this stack ventilation. This paper aims to demonstrate
investigations on the effective solar collector orientation and stack height for a solar induced ventilation
prototype that utilizes roof solar collector and vertical stack. The orientation of the solar collector is
significant as it determines the amount of solar radiation absorbed by the solar collector. Meanwhile,
the height of the vertical stack influences the creation of the stack pressure in inducing air movement.
Investigations were executed using a simulation modelling software called FloVENT. The validation
of the simulation modelling against physical experiment indicated a good agreement between these
two results. Analyses were executed on the air temperature increments inside the solar collector. A
high increment of the air temperature resulted
in the effective orientation. Meanwhile, the air
temperature and mass flow rate of the various
heights of the vertical stack were also analyzed.
The findings concluded that the recommended
orientation for the prototype’s solar collector is
the west-facing orientation. It was also found
that the higher the vertical stack, the lower the air
temperature inside the stack would be, but with
greater induced mass flow rate. |
