Initially, the room is at 25oC at bulk. This can be represented by the temperature profile at t=0 r that is at the time the two air-conditioning units are turned on. The model is based on two dimensional heat conduction at which the temperature throughout one coordinate is uniform. This can be seen from the temperature profile where temperature varies only along z and y coordinates. The following are the temperature profiles along z and y directions. Each pair of temperature profile is specific for an instant. Thus, one can determine at what time the bulk temperature of the system reaches a certain value. Bulk here is defined as the average temperature of the system.

After some time, this temperature profile is achieved. This indicates that as time passes (and that the cooling source is still present), the temperature along the two coordinates started to lower. As can be seen, the blue color which indicates low temperature started to grow to the right. That means that the temperature lowering started from cooling source to the opposite side.

Finally, steady-state temperature is achieved. At this point, the temperature distribution is invariant of time. The following shows the temperature profile at steady-state conditions.
