Study on TVOCs concentration distribution and evaluation of inhaled air quality under a re-circulated ventilation system

The indoor air quality is influenced in the long term by the chemical contaminants emitted by dried building material. The aim of this paper is to simulate the indoor total volatile organic compounds (TVOCs) distribution emitted from a new floor along with the total TVOCs quantity inhaled by an occupant with the different fresh air ratios under a re-circulated ventilation system. The simulation results and analysis are a great help to design the indoor healthy occupant environment and to improve some features of the re-circulated ventilation system.
