In Figure 7 temperature contours are plotted. A colour coded vertical plane through the building shows how temperatures vary with location. The colours relate to temperatures as indicated in the legend. Cold air leaks under the door and spreads along the floor, creating a large region under 17°C. A stratified temperature distribution is predicted with warm air floating towards the roof.
Figure 8 shows the corresponding result with the three fans operating. Since the contour plane passes through the fans, the warm jets can be seen projecting downwards. At the opposite side of the building from the door, destratification is almost complete. Close to the door, the steady flow of air into the building maintains a cold spot at ground level, but the improvement is obvious.
Figure 9 below shows the same building with four fans operating. A further improvement over figure 8 is seen; with an even more uniform temperature distribution.
