Measurements of Indoor Air Conditioned Environment and Practical Evaluations of Intake of Atmospheric Air. Part 4. Comparison of Measurement Results and Simulation Results. Part 5. Studies of Simulation Methods for Optimal Design of Air-Conditioned Environments

摘要

In the Osaka Ohbayashi Building, optimization controls of the intake of atmospheric air are incorporated, using the indoor CO sub 2 concentration as one of the indexes of the indoor environment. Previously reported results deal in detail with the correlations between the indoor CO sub 2 concentration, the number of people in the room, and the intake of atmospheric air. In the fourth paper, results are reported of a comparative study of the results of macroscopic simulation and the results of actual measuremets of the CO sub 2 concentration in a system in which the CO sub 2 concentration inside the main returning air duct is made to stand for the indoor CO sub 2 concentration in the entire building. The results showed rather good agreement between the measurement results and the simulation results. In the fifth paper, evaluations in terms of the dynamic contamination concentrations were made using a computer for a general model building. The CO sub 2 and dust were considered with reference to the air conditioning systems and the amounts of intake of atmospheric air. Cases where there were rather high rates of occupancy of offices were evaluated, and the results were used as materials for judging the dynamic effects. (ERA citation 04:045358)
