Airflow Distribution And Numerical Simulation Of Task Air Conditioning System

Airflow distribution and microenvironment of task air conditioning in a typical modern office are studied. CFD methods are use to study microenvironment of workplace and thermal comfort of human influenced by system patterns and air supplying parameters (such as supplying velocity, size supply outlet size and air blowing distance). Temperature and velocity distribution of different task air conditioning systems and different air supplying parameters are obtained from numerical results. Indexes of DR and PPD are also applied to evaluate microenvironment of workplace. Conclussions obtained by simulation establish stable basis for predicting, analyzing and evaluating air distribution of task air condioning. Simulation results indicate that task air condioning can form good thermal environment for occupants and results are beneficial for designing task air conditioning.
