Air distributor

FIELD: heating.

SUBSTANCE: invention relates to air ventilation and conditioning and can be used in rooms of different purposes. Amount of ejected air is controlled by means of a cover-flap moving in a vertical direction by means of an actuator, on the shaft of which a disc with a friction tape on its side surface is fixed; with that, the disc is in a close contact with the cover-flap, thus forming a friction pair. The actuator receives commands for the shaft rotation to this or that side from the temperature control, to which a temperature sensor is connected which is located at the device air outlet, and the outlet device at the air outlet is made of several coaxially installed diffusers and provides breakdown of an outlet air flow into several quickly damping inlet jets.

EFFECT: proposed design of an air distributor allows quick dissipation of inlet air jets in a room; with that, temperature control of inlet jets is performed in an automatic mode owing to using adjustable addition to the air supplied from an air pipeline of the air from the room due to ejection of the latter through an ejection hopper.

The invention relates to air conditioning systems and ventilation and can be used in various premises.

A well-known distributor (as the USSR №1717908, 1991), comprising a housing with an outlet hole at the outlet is attached to the duct using a cylindrical inlet pipe, performed on the surface of the last ejecting window installed in the inlet pipe confused insert, and the body is made diffuser and provided attached to its output bottom with outlet holes with secretively air, and placed parallel to the bottom perforated flap that can be rotated around the axis, and the bottom flap is made in the form of spherical segments, convex to the inlet pipe, and a cylindrical inlet pipe provided with a covering of its elastic cuff attached by its edge to the inlet pipe before ejecting Windows along the air can travel along the latter and their overlap.

The disadvantage of such a diffuser is not intensive enough attenuation of the air supply jets, and by changing the position of the perforated flaps when turning around the axis changes only air flow that does not have a significant effect on the damping of the velocity of the th inlet jets.

Known air (patent RF №2250419, 1995) - the closest analogue containing diffuser case from the exhaust holes on the outlet is attached to the duct using a cylindrical inlet pipe, performed on the surface of the last ejecting window, with inlet pipe provided with a covering of its elastic cuff, is rigidly attached by its edge to the inlet pipe before ejecting Windows along the air can travel along the latter and their overlap, installed in the inlet pipe confused insert in the bottom of the casing having the shape of a spherical segment and is convex inside of the case, made a round hole above which inside the housing concentric with the bottom placed the partition wall having the shape similar to the bottom, and the surface is greater than the diameter of the hole, while between the edges of the hole and the wall radius of the hole is set plates forming channels for the passage of air, and between the plates installed secretively air.

The disadvantages of this design are:

- the complexity of the design for the implementation of its Assembly;

- large aerodynamic drag caused by design features to release air from the case.

The aim of the invention is POPs is the use of a more simple design of the diffuser, providing a lower aerodynamic resistance to passage of air.

This goal is achieved due to the fact that in the proposed design of the diffuser is used, the housing is cylindrical and is attached to the duct using a cylindrical inlet pipe, the lower part of the body has a confused form and shipped in ejection funnel attached coaxially to the housing by means of rods, inlet funnel equipped with a flange, the body is equipped with an external thread, which can move in the vertical direction cover-flap fitted in the center hole is threaded, the lower surface of the cover flap equipped with a sealing gasket, with an outlet of the ejection funnel attached consisting of several coaxially mounted diffusers output device, and on the axis of the actuator cover-flap fixed disk on the side surface of which is secured a strip of friction material, while the side surface of the cap-damper and friction tape are in close contact, forming, thus, the friction pair "disc valve"; actuator electrically connected with the temperature controller connected to the air temperature sensor, placed in a room near an exit of the air is from the output device.

Such design of the diffuser is more simple in comparison with the closest analogue, and the absence of inside the diffuser elements, preventing the passage of air flow, it provides small wind resistance, and output device, consisting of several coaxially mounted diffusers, provides rapid dispersion of the inflowing streams.

Dialysis analogues showed that the claimed technical solution is new. The novelty of the solution is that the lower part of the cylindrical body of the distributor has a confused form and is shipped in ejecting the funnel, the inlet of which is equipped with a flange on the external body threads can move the cover-flap regulating the suction of air from the room, the air outlet of the air is accomplished through several coaxially mounted diffusers that provide a rapid attenuation of the inflowing streams by dividing the air stream into multiple streams. Regulation of air leaks from the premises (ejection) is controlled by the actuator, the axis of which is placed a disk, provided on the side surface friction tape, friction tape and cover-flap are in close contact and form a friction pair.

Thus, awseme technical solution is characterized by a new set of essential features, giving a positive effect, i.e. has signs of compliance with the criterion of "inventive step".

Figure 1 shows the proposed diffuser containing a cylindrical housing 1 is attached to the duct 2 through the cylindrical inlet pipe flanges 3 4 (flanges 4 in the subject invention are not included in the formula not shown). The lower part of the housing 1 is made in the form of a confusor 5, ejection funnel 6 is equipped at the inlet 7 of the flange 8. Funnel 6 is fixed to the body 1 by the rods 9. The housing 1 is equipped with an external thread 10. Cover-flap 11 is fitted in the hole 12 thread 13 (corresponding to the thread 10 of the body 3), on the bottom surface of the cover flap 11 is fixed to the sealing gasket 14. To the outlet 15 ejection funnel 6 is attached consisting of several coaxially mounted diffusers output device 16. The actuator 17 is equipped with a disk 18, is attached to the axis 19 of the actuator 17. On the side surface of the disk 18 mounted friction tape 20. Disc 18 (with friction tape 20) and the cover-flap 11 are in close contact, forming a friction couple. The actuator 17 is attached by the bracket 21 to the duct 2 (bracket 21 on the subject of the invention is not included in the formula not shown). The actuator 17 is connected electrically with Regulus in the torus temperature 22, connected to the temperature sensor 23.

The diffuser works as follows. Coming from the duct 2 air through inlet pipe 3 enters the cylindrical body 1 of the diffuser and passing through the confuser 5 at the outlet of the housing 1, slightly increases its speed. As the confuser 5 immersed in the ejection funnel 6, the upper part of the funnel 6 creates a slight vacuum in the result through the inlet 7 into the funnel 6 ejectives (sucked) the air from the upper zone of the room where is the distributor. The number suctioning air can be regulated by the cover flap 11 depending on the set the temperature controller 22 setpoint. Coming in ejection funnel 6, the air duct 2 (from air conditioning systems in the formula are not included in figure 1 is not shown) is mixed with air that is sucked into the funnel 6 from the premises, and changes its temperature. The position of the cover flap 11 determines the magnitude of the gap between the flange 8 of the funnel 6 and the cover flap 11, thereby changing the amount of drawn air. From the air temperature sensor 23 is continuously output signals to the temperature controller 22. The change in temperature at the exit of the diffuser output device 16, fixed Yes the chick 23, results (if the temperature relative to the set point on the controller 22) to flow from the controller 22 commands the actuator 17 to rotate in one direction or another. The result comes in a rotation of the shaft 19 of the actuator 17 and mounted on the shaft 19 of the disk 18, as well as fixed on the side surface of the disk friction tape 20 is tightly in contact with the side surfaces of the plate-valve 11, the latter rotating in the thread 10 of the housing 1, is moved in a vertical direction up or down, changing the gap between the flange 8 of the funnel 6 and the cover flap 11, thus changing the amount of drawn air and the temperature of the mixed air. When the appropriate command temperature controller 22, the actuator 17 can completely block the access of air into the funnel 6 from the premises. When the gasket 14 provides a tight pressing of the cover-flap 11 to the flange 8; fixed to the output 15 of the air from the funnel 6, the output device 16 (consisting of several coaxially mounted confusion) provides rapid dissipation of the supply air jets in the room due to the breakdown of the output air stream into multiple streams.

The proposed diffuser is industrially applicable, as its structure does not contain parts that can't be made, and not PR is dstanley difficulties during installation.

The inventive diffuser provides a simpler design in comparison with analogues. Aerodynamic resistance of the device is considerably less than that of the analogues, since no obstacle to the passage of fresh air inside the air and on the exit of inlet jets.
