Introduction • In this workshop you will be analyzing the effect of computers and workers on

the temperature distribution in an office. In the first stage airflow through the supply air ducts will be simulated and the outlet conditions for the duct will be used to set the inlet conditions for for the room. • Although both components could be analyzed together, separating the two components allows different room configurations to be analyzed without

solving the duct flow again.
