During a wedding, concert, corporate, festival or banquet, the load on the air increases very quickly, people gather in separate areas, move, dance, stand at the stage or sit for a dense landing, and the lights, kitchen and equipment add heat.
If the air does not move evenly, overheating appears in the center of activity, it becomes difficult to be in the crowd, and stuffiness is felt in closed and partially closed areas even at normal temperature.
