Abstract

Natural disasters are often mentioned in Malaysia, and floods are one of the disasters that occur in our country every year. Due to this disaster, flood victims will be sent to evacuation centres to seek temporary shelter. Occupants in evacuation centres face various problems, including poor ventilation. Due to poor ventilation, the occupant quickly feels hot and uncomfortable while in the evacuation centre. A sampling of temperature and nature airflow velocity data is done at different floor levels every 30 minutes for 24 hours at SMK Bukit katil Melaka, Malaysia, used as a temporary evacuation centre. The data will be simulated in Ansys Workbench to get an airflow view consisting of two conditions: the classroom equipped with a tent and the classroom not fitted with a tent. The average air velocity and temperature result in the three floors is 0.47 m/s and 27.2 ° C for the ground floor, 0.64 m/s and 27.1 ° C for the first floor, and 1.33 m/s and 27.2 ° C for the second floor. And the simulation results from the Ansys Workbench software performed on all the floor levers showed the following readings: The average is 0.28 m/s (no tent) and 0.14 m/s (included tent) for the ground floor, 0.34 m/s (no tent) and 0.28 m/s (tent included) for the first floor, and 0.63 m/s (no tent) and 0.59 m /s (included tent) for the second floor. The study results found that the wind speed at each different floor level is different. And the results of the simulations on the three floors showed a slower wind speed after using the tent. This study can help the social welfare department provide a more comfortable evacuation centre. Level selection and installation of the tent at the correct floor level will help the victim achieve thermal comfort in natural ventilation.
