This paper is concerned with the different methods to present inlet condition for computational fluid dynamics (CFD) simulation of task air conditioning (TAC). The boundary conditions at the supply opening have a strong influence on the flow in the room, and they are, therefore, very important. Usual methods are outlined. Comparison and analysis are then given. The terminal device of TAC is close to people and is relatively large compared to the dimension of the occupied zone. The occupied zone is in the forward flow zone, not return flow zone.
