Abstract : In this paper, air distribution parameters inside the selected control room in cooling mode ventilated by cassette type air conditioner was analyzed. In this work, the investigation in both experimentally and numerically have been conducted. An proper control room was selected for experiment design with dimensions of 4.8m width, 5m length, and 3.55m height. Furthermore, the instrument devices for measuring the air temperature and air velocity were arranged and prepared. An ANSYS workbench softwa
