We simplified the room for long 6m, width 5m, 3m high cuboid, and it was an adiabatic system without any form of heat exchange with the external environment, in addtion the indoor air density was constant, and ignoring the influence generating from interior obstacles material (heat, tables, chairs, lamps, activities, etc.) on the air flow.
