Title: The Numerical Simulation of an Air-conditioning Office with Different Air-supply Velocity
Abstract: Airflow distribution is the technique of controlling and arranging the air flow in the air-conditioning area.The quality of it takes an important part in the air-conditioning effect.The temperature of supply air has a direct relation with the airflow distribution.Taking one of office as model room,the relative mathematical and physical models are established,and indoor airflow of the model room at different air supply temperatures is simulated with CFD software:Airpak.The fields of air temperature,velocity are offered.The relation between air supply temperature and the field of air temperature and velocity is achieved.Finally,we valuate the airflow distribution with energy index η and get a best air supply temperature.The result indicates that the air-flow form and velocity at one point is hardly changed,the temperature increases and the temperature gradient decreases while the air-supply velocity is decreasing.
