Abstract

This study aims to predict, as well as analyze the temperature and air velocity in a room that has the installation of two split AC units. The CFD simulation approach is applied in this study by preceded experimental measurements on actual conditions for data validation. In this study, the room measuring 10.45 m x 8.1 m x 3.92 m located in Room H 404 Faculty of Engineering serve as a simulation object. Air velocity variations measured at the front of the evaporator, ie at AC unit 1 = 5 m/s, while AC unit 2 = 3.2 m/s. The simulation process begins with validating three different types of mesh 149328 elements, 327440 elements, 971209 elements as the standard step that must be passed on simulation / computation based research to determine mesh construction that can produce simulation data than measurement data. The assumption in the simulation is empty space and there is no influence of heat from outside the room. Based on the validation done, the mesh construction with 971209 elements can provide the most accurate prediction Temperature and air velocity with the difference level the measurement result of 1.02%. Simulation of three variations of turbulance model (Standart, Realizable And RNG) showed that no significant effect on the average temperature in the room where obtained results of 24.07, 23.85 and 23.19 ° C. While the average air velocity in the room increased in each variation obtained results 0.105, 0.111 and 0.104 m / s.
