Abstract

This study aims to predict the distribution of temperature and airflow patterns in a class room with dimension of 10.45 m x 8.1 m x 3.93 m. Cooling machine used is one AC type Split with power 2 PK. This study was realizedby the measurements of air temperature inside the class room at several reference points will be used for validation and comparison. The measurement position was set at 1m height from the floor. The steady RANS simulation applied the k - epsilon turbulence model with three different structured mesh types up to 1.211.358 elements. The mesh type capable of producing simulation data closest to the temperature measurement data will be further developed to investigate indoor air circulation due to the effect of inlet temperatures on the evaporator. Three temperature were varied at 18 ; 24 ;dan 30 oC. The results show that the finest mesh construction is able to produce prediction of simulation data with error rate up to 2.257%. In the investigation of the three different temperature conditions, the distribution of temperature and airflow patterns not much different from the actual conditions . As the temperatur increases, the temperature distribution and airflow patterns are also increase and are evenly distributed throughout the class room
