Abstract

Turbine ventilator becomes a preferable option nowadays to ventilate spaces due to negligible operating costs and a great performance offered. Turbine ventilator basically performs at an optimum level in premises that are having at least 150% of opening air. However, modern premises nowadays are designed having insufficient opening air intake. Thus, the modification towards the existing turbine ventilator seems crucial to be done. In this study, some modifications towards the existing turbine ventilator were made by adding a fan which was joined to a set of propeller. The performance of modified turbine ventilator in improving thermal comfort level was examined and compared with the existing turbine ventilator. Predicted Mean Vote (PMV) of 1.686 and Percentage People Dissatisfied (PPD) of 59% were recorded for a premise with existing turbine ventilator. Whereas, for a premise with modified turbine ventilator PMV and PPD recorded respectively were 1.503 and 51%. It is proven that the modified turbine ventilator offers a promising performance in improving thermal comfort level.
