Effectivity Wind Catcher At Housing In Limited Areas In Hot-Humid Tropical Climate

The function of cross ventilation for removing accumulated heat inside houses for hot-humid tropical climate is difficult to cope, as the house has very limited house areas. This study discusses the effectiveness of wind catcher on housing in a limited in the hot-humid tropics, due to the use of cross ventilation is not possible, this research tries weeks to use the opening in the roof of the principle of wind driven ventilation is wind catcher. By measuring the real condition in the existing houses, the study aimed to investigate the thermal performance inside the houses. Furthermore simulation is conducted to improve the thermal condition. Wind catcher is introduced in the house. The simulation process primarily utilizes the CFD software: Fluent version 6.2 to explore wind-driven ventilation method. The results show that 3 and 4 meter-height, 0.7x0.7m cross- section and 0.5x0.5 opening hole of wind catcher is effective in improving indoor thermal condition. The effectiveness is demonstrated in increasing airflow velocity from 0.15 m/sec to 0.82 m/sec and reducing temperature of 5.3°C
