Abstract

An appropriate ventilation system design not only increases the indoor ventilation effect but effectively improves the particle concentration distribution. The locations of indoor furniture are used to analyze the indoor airflow and particle distribution by numerical skill in this study. Also, a 45 cm × 45 cm × 45 cm chamber is setup as experiment apparatus which is made by acrylic resin board with 16 holes connected to supply air flow. In order to simulate the furniture effect, some wooden blocks are located at the chamber. The temperature and humidity sensors are connected to the data acquisition system with a personal computer to record all the test data. The experimental results show that much more deposited mass will be observed in isolated zone than that in other area and the maximum simulated suspending particles will exist at the vortex zone where the aerosol distribution keeps almost constant.
