Floor swirl diffusers used in air-conditioning system would create good air mixing to create indoor air comfort conditions and help in achieving human comfort. The variation in temperature in air conditioning system depends strongly on the flow characteristics produced by the diffuser outlet that vary considerably between different modeling set ups. In corporate sector it is very important to calculate the effect of variation in temperature of diffused air from floor swirl diffuser with and without heat load.The analysis has been performed inside a wooden room of size 4ft x 4ft x 5ft with swirl diffuser models installed at the roof. The variation in temperature of diffused air form floor swirl diffuser at different height and the effect of heat load on temperature variation is determined. This analysis has been performed on three different models of floor swirl diffuser having different slot angles of 7�, 8� and 9�and at different wind velocities i.e. 2, 3, 4,5m/s.
