Sets Of Indoor Human Thermal Comfort And Air Quality Research

Providing for the wholesome and comfortable indoor microcimate is very important, because the microclimate can affect on the health, the mind and work efficiency of the human being. In accordance with an apartment unit, the thermal comfort of occupants and indoor air quality is studied numerically in this paper. The distributions of airflow velocity, air temperature and thermal comfort index of the apartment unit are acquired. The results of calculation are validated by a computational example. Some related experiment is conducted with the constant thermal anemometer. The study object is an apartment unit with two bedrooms and one hail. When the mathematics model is founded, some conditions are taken into account such as solar radiation, outdoor temperature, structure of enclosure, furniture and occupants indoor. After the program is worked out, the simulation is made with the software of PHEONICS. The distributions of air temperature, air velocity and thermal comfort index are gotten. The thermal comfort index is evaluated and the form of airflow distribution is analyzed. The valid scientific judgements and analysis means are supplied to the view of optimization of the indoor microclimate of the buildings, which is used to live. Some concrete improvement means and advice are presented. An example is applied to validation of the numerical simulation. A single model is used to measure the data of air velocity with the constant thermal anemometer and the data is analyzed. Numerical simulation of the single model is validated with the data of experiment. In short, this study is valuable of the providing for the satisfied indoor environment.
