Description

54) AIR DISTRIBUTOR

The invention relates to ventilation and can be used to supply air to various types of rooms. A distributor is known that includes a spiral casing with an inlet pipe, a disk with a central hole placed under the casing, a pipe mounted on the disk and a reflector mounted under the disk.

A disadvantage of the known air distributor is that it does not provide effective quenching of the inflow rate.

The purpose of the invention is to intensify the quenching of the speed of the supply jet.

The goal is achieved by the fact that the air distributor containing a spiral casing with an outlet nozzle, placed under the casing with a central hole, is passed through the casing to a pipe fixed to. the disk and the reflector mounted under the disk are provided with a second spiral housing mounted on the housing and communicated with the pipe with an inlet pipe located on the side opposite to the inlet pipe of the first housing.

Figure 1 shows the air. divider, longitudinal section; figure 2 is the same, top view.

The air distributor contains a spiral case I with an inlet pipe 2, placed under the case 1 disk 3 with a central hole 4, passed through the case 1 pipe 5, mounted on disk 3, and installed 10 reflector 6 under the disk 3, and the air distributor is equipped with 1 and communicating with the pipe 5 with the second spiral casing 7 with the inlet pipe 8 located on the side opposite to the inlet pipe 2 of the first body 1.

The air distributor operates as follows.

The supply air is supplied by ocHOBHtw and additional flows. The main stream entering the spiral casing 1 twists and, exiting from it, is reflected from disk 3, spreading out in the form of a circular fan jet.

Claims (1)

The additional flow entering the spiral casing 7 also twists and, having passed the pipe 5, spreads 30 s onto the reflector 6, has expired in the form of a circular fan jet having a rotation opposite to the rotation in the case 1. At the contact of two rotating: flows having opposite direction, intensive on the loss of their kinetic energy, which leads to a decrease in speed at the exact torch. When the additional flow is heated, the rate of quenching of the main flow rate increases. The proposed air distributor provides the intensification of quenching the velocity of the inlet stream. An air distributor comprising a spiral casing with an inlet pipe, a disk with a central opening placed under the casing, a pipe mounted on the disk through the casing, and a reflector installed under the disk. provided with a second spiral housing mounted on the housing and in communication with the pipe, with an inlet pipe located on the side opposite to the inlet pipe of the first case.
