Abstract

The invention relates to a technique of ventilation and allows maintaining a predetermined speed of the air flow in the working area by increasing the degree of air flow attenuation. , Case I is made of double-skinned outer and inner truncated cones and adjoining cylindrical shells to their large bases. The inlet 2 is located coaxially with the exhaust pipe 4 with the formation of a gap 5 between their ends and is communicated; with interstitial space 6 of housing 1. The inner truncated cone is attached to the end of pipe 4 on the side of the gap 5 and forms an annular pocket 7 with its outer surface. Part of the flow is distributed around the room by an annular jet, another part of the flow is reflected from the disk reflector 3, it unfolds and is distributed by horizontal fan jets. When a fan of horizontal and annular jets collides, their velocities are quenched, and in the pocket 7 closed circulation zones are formed, in which some of the kinetic energy of the total air flow is also lost. 2 Il. about S (L / 7 from to to about about 0ue.Z

The invention relates to the field of ventilation and can be used in industrial ventilation systems of industrial buildings, for example, to distribute supply air in reconstructed workshops using an in-use ventilation system to maintain the normalized air velocity in the working (served) zone. flow.

The aim of the invention is to maintain a predetermined air flow rate in the working area by increasing the degree of air flow attenuation.

FIG. 1 image: air distributor, general view; figure 2 - section aa in fig ..

The air distributor includes a housing 1 with a BnycKHbRv tube 2, placed under the housing 1, a disk reflector 3 and a discharge pipe 4 concentrically located in the housing 1 4. The inlet 2 is located coaxially to the outlet pipe 4 with the formation of a gap 5 between their ends; outer and inner truncated cones, coupled with their large {and base cylindrical shells, and the inlet pipe 2 communicates with the interstitial space 6 of housing I, and the inner truncated cone is attached to the end of the exhaust pipe 4 from the side

The other part of the air passes through the exhaust pipe 4 to the disk reflector 3. The air flow, reflected from the disc reflector 3, is turned and distributed by horizontal fan jets. That part of the air flow that entered the interwall space 6 of the double-walled body 1 is distributed around the room (not shown) by an annular jet. During the collision of fan-shaped horizontal and annular jets, their velocities are quenched, and in the annular pocket 7 closed circulation zones are formed, in which a part of the conical energy of this total air flow is also lost.

Claims (1)

Invention Formula An air distributor comprising a housing with an inlet duct, a disk reflector located under the housing and an outlet tube concentrically located in the housing, characterized in that, in order to maintain a predetermined air flow rate in the working zone by increasing the air flow attenuation, the inlet located coaxially with the exhaust pipe with the formation of a gap between their ends, the body is made of double-walled outer and The gap 5 also forms an annular pocket 7 with its outer inner 35 truncated cones and co-supersity.
