In designing air-conditioning systems for large-scale indoor spaces, it is important to predict the air velocity and temperature distributions in such spaces to enable indoor climate to be controlled effectively. The indoor climate can be predicted by two numerical simulation methods: one is a rough study by using a macroscopic model and the other is numerical simulation based on a turbulence model. Each method has its own limitations. For instance, the former method cannot provide the detail data of the flow and temperature fields whereas the latter method has a drawback in that it is difficult to determine proper boundary conditions concerned with heat transfer at wall surfaces for the numerical simulation study. This paper describes the results of studies on indoor climate of a large- scale space by these two methods, and presents that the problems involved can be solved by the combined use of two methods.
