Abstract

Air flow distribution refers to the air circulation in the classroom. Students unable to concentrate and feel distracted from the class activity due to their need comfortable surroundings. Lack of environmental parameter such as air velocity and air temperature cause of air distirbution in the classroom will result in environmental stress and negative trends toward occupants during teaching and learning session. This study is focused on the monitor and simulate the air flow distribution at three different preschools in Malacca which are Tadika Kemas Rumah Pangsa Kampung Padang, Tadika Kemas Kampung Padang A and Tadika Kemas Kampung Padang B. The goal of this research is to discover the appropriate flow of air circulation that should be present throughout the learning process. It has been found that the value of environmental parameter of these preschools out of acceptable range value based on standard recommended by ASHRAE 55 - 2010 as well as Industry Code of Practice Indoor Air Quality, DOSH Malaysia (2010). Several data collection of environmental parameter more conducted air velocity and air temperature by using TSI VelociCalc instrument to improve air flow distribution in the classroom at three preschools. By using CFD simulation analysis tool method, an appropriate layout to improve air circulation are conduct. It will carry out four probability layouts of classroom for each three different preschools. From the simulation of all probability layouts, it carries of detailed map-out of air flow distribusion consist of air velocity and air temperature on the classroom of each three preschools. As a result of probability layouts, it can optimize which is the best layout of classroom that consists of great enviromental parameter to be used as classroom layout for each preschool. The suitable layout to be use for preschool Tadika Kemas Rumah Pangsa Kampung Padang is the layout (b), preschool Tadika Kemas Kampung Padang A is layout (a), and preschool Tadika Kemas Kampung Padang B is layout (c). The best selected layout that suitable to be used to classroom at preschool is because consist the combination quality of air velocity and air temperature. By conclusion, the best selected layout of classroom for each three different preschool can solved the discomfortness of occupants in the classroom especially during teaching and learning session.
