(54) VENTILATION DEVICE FOR AIR DISTRIBUTION BY ROOM

(57) Invention m. used for ventilation of vehicle cabs. The purpose of the invention is to increase comfort and uniformity.

, air distribution by volume of the room. In the outlet openings 2 placed in the front wall 3 of the box 1, the flow curlers 4 are installed with guiding peaks 5. The dissecting plates 6 are installed in the box 1 with the formation of equal-sized sections perpendicular to the wall 3. An optical diffuser is attached to the wall 3 chamber 7. In the side walls 9, discharge ports 10 are made, in which valves are installed. In the chamber 7, the swirling and return flows are mixed, and under the action of static pressure, the air is squeezed out by a uniform flow, 1 sludge.

The invention relates to ventilation and air conditioning and can be used in rooms such as cabs of vehicles, consoles and control stations.

The purpose of the invention is to increase the comfort and uniformity of air distribution over the volume of the room.

The drawing shows the device, the overall appearance.

The ventilation device for distributing air to a room (not shown) contains a duct 1 with outlets 2 in its front 15, and the air is squeezed out evenly.

wall 3 and swirlers 4 installed in the holes x 2 with guiding visors 5. The air distributor additionally contains dissecting plates 6 installed in the box 1 with the formation of equal-sized osots, perpendicular to the front wall 3, the static diffuser alignment chamber 7 flow, attached to the wall 3 and blocked by a grid 8. while in the side walls 9 of the box 1 there are additional outlets 10 in which valves (not shown) are installed.

The device works as follows.

The incoming air entering the duct 1, meets in its path dissecting plates 6, is divided into equal-sized compartments and is evenly distributed both in the lower part of duct 1 with outlet openings 2 and the curlers 4 accommodated in them and in the hole 10

on the side walls 9 of duct 1, from where it diverges by horizontal jets spreading on the cabin ceiling. Moreover, the air mobility at the workplace can be regulated by valves (not shown), closing the holes 10. Being distributed to the lower part of the box 1, the air is pushed out of the outflow holes 2 into the static diffuser chamber 7, where the twisted and reverse flows are mixed, and mostly static pressure

flow through the grid 5 into the room. It also contributes to the uniform distribution of air to a fixed workplace.
