METHOD FOR PREDICTING CONCENTRATION DISTRIBUTION OF MICROPARTICLES, DEVICE FOR ANALYSIS, PROGRAM PRODUCT FOR PREDICTING CONCENTRATION DISTRIBUTION OF MICROPARTICLES, BULDING AND DEVICE FOR DIFFUSING MICROPARTICLES DESIGNED BY USING SAID METHOD FOR PREDICTION

摘要

A method for predicting local concentrations of short-lived microparticles having an unstable composition in a room simply and in a short time is provided. The method for predicting the concentration distribution of microparticles includes the steps of determining a flow field in a room (#23), determining the age-of-air distribution in the room on the basis of the flow field in the room (#24), and converting the age of air into the concentration of the microparticles (#25).
