The purpose of the present study was to evaluate the possibility to reproduce heat and air flowcharacteristics in a machine room where high heat generating systems and devices are installed. For this purpose, in an experiment room was air-conditioned by double floor air supply on the assumption that the machine room, data were selected such as air flow rate of the systems and various boundary conditions were elected. Further, double floor supply air flow rate distribution, and heat and air flow distribution in the room were measured. The results of CFD calculation on the model of the entire room including double floor were compared with the results of actual measurement. It was confirmed that it is possible to satisfactorily reproduce air flow distribution, temperature distribution, and distribution of floor supply air flow rate and to predict indoor environment in a room with double floor air supply air-conditioning system by CFD.
