Prediction of Indoor TVOCs Concentration Distribution: Part Ⅲ With Different Ratios of Fresh Air and Return Air

摘要

The unsteady simulations for TVOCs emission process of the drying building material have been done and a special focus was given on the occupant zone under the different mixing ratios of inlet and outlet air. According to comparison of calculation results of the different cases, the inlet velocity may be the dominating influence factor to affect the main pattern of concentration distribution, but nearly the same difference value of meaning TVOCs concentration was produced along the time passing. The concentration inside material was nearly same at the same height The concentration at left side and left-bottom corner were always lager than that at the other places, it is worthy of paying more attention by the user and designer.
