This means that there is a non-uniform air outlet area on the front side of the device and on the outside of the slot 48. The holes 54 in the 6 side edge portions 50 and corresponding corner portions to prevent them from being clearly defined are It helps equalize the flow of gas or air in areas of prevent this from occurring. The centrally located air distribution plate 25 is the front plate. This is effective in restricting the airflow in the center of the vehicle. This air throttling effect is caused by the baffle Together with the guiding effect provided by the support root 30 and the outwardly directed portion 31, the present invention It serves to direct air to areas located immediately in front and to the sides of the air distribution device.

The usage of this air distribution device 10 is briefly described as follows. conduit( Air (arrow 56) enters the device from the air distribution and restriction plate 32 (not shown). is decelerated by the inlet sleeve 12 and passes through the rear large plate 35 to the rear plate 16 of the distribution chamber. , and descends evenly through mutually parallel large plates 36. do. As a result, a negative pressure is created in the non-perforated area 38 on the underside of the plate 32, and the inlet air Air flows downwardly through the distribution chamber 14, where the air is directed into the region 38 as previously described. During this period, a partial airflow is continuously directed forward by the rail 26. rail The upwardly bent portion 28 of 26 is a splitter (spl 1tter). It functions to isolate the portion of the incoming airflow closest to the front of the device. Rear plate 1 6 is tilted, so the chamber 14 is narrower at the bottom, and the air can flow through the entire chamber 14. airflow at substantially the same speed over the length, and the same amount of airflow is flowed by the guide rail. guided outward through the front cover plate.

Wall-mounted air distribution devices constructed in accordance with the present invention generally The studs (studs) are installed in a stud structure spaced at 70a+m intervals. It has become so. For this purpose, the inlet sleeve has everything that can be obtained between the studs. Preferably, the dimensions are 60 x approximately 500, so that a space of approximately 500 is available. Device The device itself is 600mm wide and 300-900mm high (left and right depending on the relevant air conditions). The diameter of the hole in the distribution plate 32 is generally in the range of 8 to 16 cm. This also depends on the relevant air conditions. front cover plate It is suitable to have a hole with a diameter of 51 and a center distance of 7.51. The device 10 is installed from the floor. Preferably, they are arranged at intervals of 10 cm.

The inner side edge is bent upward around the central hole 129 of the annular body (rail). , forming a rising collar 128. The annular rail 12B includes a plurality of vertical baffles. - Supported by support plate 130. Bar support plate 130 is at least 3, preferably 4 or more. Center of annular guide rail 126 The hole 129 increases in depth, ie, as the distance from the inlet sleeve 112 increases. The dimensions of the lower distribution chamber become smaller and the lower distribution chamber becomes narrower. Again, the guide The rails 126 and/or the vertical support plates 130 are provided with slots that This ensures that the rail is securely attached and remains in place.

Plate 130 serves to support annular guide rail 126 and also supports horizontal It has the role of guiding outflow ventilation air. Therefore, the need for such guidance If the number of baffles and support plates 130 is large, multiple baffle and support plates 130 are provided.

This may be the case, for example, when the air distribution device 110 ventilates only a portion of its surroundings. The other part is a shield placed near the perforated front cover plate 124. It is blocked by a plate (not shown). In this case, the plate 130 is Preferably, it is arranged along the edge of the blocking plate.

As shown in FIG. 5, the horizontal portion of each rail 126 (preferably a collar 128) It would be good if a hole with a diameter of, for example, 2 mm could be made. These holes allow a certain amount of air can pass through the guide rail surface and the guide rail collar. child This prevents negative pressure areas from forming under the guide rail and/or outside the collar. 6 In such negative pressure regions, return flow and turbulence occur, thereby reducing air distribution. This can create acoustic and fluid disturbances to the flow exiting the device.

The inlet sleeve 112 connects to the inlet box or inlet chamber 131 and is connected to the bottom of the inlet chamber 131. is bounded by a distribution and aperture plate 132.

Similar to the first embodiment described above, the flow flows through the secondary air boat 142. be introduced. This suction of secondary air into the air distribution device causes the secondary air to enter the device. It is also obtained by the ejector effect that occurs as a result of the flow velocity.

By introducing secondary air into the device as described above, the amount of air released from the device can be reduced. The amount of air that can be ventilated can be increased, and the area or area that can be effectively ventilated can also be increased. On the other hand, maintaining the total amount of desired fresh air from an external fresh air source to a minimum Can be done. This reduces the energy required to transport and heat the fresh air delivered to the equipment. energy costs are reduced, minimizing overall ventilation costs.
