<p>PROBLEM TO BE SOLVED: To provide an indoor air environment management system capable of analyzing dispersion of tobacco smoke leaked from a smoking region to a non-smoking region at low cost.SOLUTION: A first to N-th (N: a natural number equal to or more than 2) temperature sensors TS measure surrounding air temperatures. An indoor air management part 300 comprises a data base and a concentration calculation part. The data base stores temperature sensitivities a(i,j) indicating a value in which a variation amountΔT(i) of temperature of air flowing into a surrounding part of an i-th (i=1 to N) temperature sensor is divided by a variation amountΔT(j) of temperature of air flowing out of a surrounding part of a j-th (j=1 to N) temperature sensor. The concentration calculating part calculates a concentrationφ(i) of tobacco smoke around the i-th temperature sensor in reference to a pre-inputted concentration of smoke around the temperature sensor installed in the smoking region and a flow rate distribution ratio around the i-th temperature sensor based on the temperature sensitivity a(i,j).</p> |
