The flow of air in the room

Fig. 24.17(a) shows a typical office or hotel room with a flow channel in the Central corridor of the ceiling and the wall grille to direct the air flow towards the window, which, as a rule, the main source of heat gain or loss. High level of discharges of this type work best when cooling the incoming air jet fall as he crosses the room. The heating she will tend to rise, and so should be enough speed to configure the forced circulation, as shown.

Fig. 24.17(b) shows the perimeter of the blocks under the window and unloading of up to absorb the heat flow through the window. The angle and speed of discharge should be enough air to install circulation in the room to get to the far wall or, in the room with open-plan area covered by the neighbouring lattice. In these units, the air is returned to the person or in the lower part.

Fig. 24.17(c) shows, floor slots, setting on the model of the perimeter units. This agreement was adopted in some of the buildings, with all glass walls. The position of return grille varies depending on the room layout and stagnant zones may occur.

Fig. 24.17(d) shows ceiling lattice or slots, requiring that all ducts to be in the void of the ceiling. This system is usually taken to an open-plan rooms, since the region may be divided into stripes are interleaved with the exhaust slots, or squares (or near squares) for intake and exhaust on the lattice. I t will be seen that all these structures require some attention and planning, because the best equipment cannot cope with the incredible air circuit.
