DEVELOPMENT OF A MEASUREMENT METHOD FOR AIR CURRENT BY THE USE OF BALLOONS FOR GRAVITY FREE

摘要

Designing an effective air-conditioning system for a large space requires precious planning by numerical simulation, and modification of the utilization of systems based on the measurement result. Recently, numerical analyses, such as CFD, have frequently been used in the planning of a thermal and air environment for a large space. Although simulation results are often used for planning, there have been few case in which the results of actual measurement of air currents inside a large space after completion of construction. One reason for this is the difficulty of measuring air currents in a large space. In this report, presents a simple method for visualizing air currents and for estimating distribution of air movements are presented.
