This paper investigates numerically the effects of forced circulation on transient thermal distribution and fluid flow inside a room with through-flow resulting from a warm influx as well as a cold influx. An adiabatic spacer is vertically placed on the side wall of the room. The effects of the spacer on suppression of thermal stratification in the room are visualized graphically. A two-dimensional laminar system is adopted. There is an optimum spacer location for ensuring the following conditions in case of the cooling, even if the inlet air velocity changes; (i) the heat exchange characteristics can be ensured, (ii) the cold air is not stratified in the floor of the indoor, (iii) the air flow of the pleasant temperature in the indoor can be ensured.
