The invention relates to heating, ventilation and air conditioning, and can be used in heating, cooling, supply ventilation and air conditioning systems in industrial premises, enterprises of electronic industry and precision instrumentation.

According to the main author. St. No. 785606 is known for an air distributor containing a constant cross section duct with a longitudinal slit of a constant cross section along its entire length. A leveling resistance made in the form of a filter is installed in front of the slit inside the box, and a reflecting plate is installed at the exit of the slit consisting of two elements, each of which is fixed on the longitudinal axis with the possibility of rotation. Inside the box on its wall, in which a longitudinal slit is made, there is a coil connected to a heat source - refrigerant 1.

A disadvantage of the known air distributor is the lack of a constant blowing of the bottom base of the duct, since under the conditions of the air distribution the opening angle of the rotary reflecting plates may vary and not provide air distribution by flat streams with the specified surface. As a result, when the temperature of the bottom side of the duct is below the dew point temperature of the air placed on it, condensation may form. Maintaining a lower temperature of the bottom side of the box will increase the efficiency of heat transfer.

In addition, a disadvantage is also the impossibility of creating a two-jet air supply by flooring and fan jets.

The purpose of the invention is to increase the heat transfer of the box.

This goal is achieved by the fact that in an air distributor containing a constant cross section box with a longitudinal continuous cross section along its entire length, an equalizing resistance is set up in front of the opening inside the conduit, and a reflecting plate is installed at the outlet of the opening The conduit consists of two elements, each of which is fixed on the longitudinal axis with the possibility of rotation, inside the box on it. a wall in which a longitudinal slit is made is located a coil connected to a heat source — a coolant; on the duct wall on both sides of the longitudinal slit in front of the reflecting plate along the air path are mounted with vertical and horizontal movement spring-loaded guide plates parallel to the bottom wall box.

5 The air distributor contains a duct of 1 constant cross section with a longitudinal slit 2 of constant cross section along its entire length. Before slit 2 inside the box 1 is set equalizing resistance 3, made in the form of a filter, and the output

 From the slit 2, a reflecting plate 4 is installed, consisting of two elements, each of which is fixed on the longitudinal axis 5 with the possibility of rotation. Inside the box 1 on its wall, which is made longitudinally on the slit 2, there is a coil 6, connected to the heat source 7 - a coolant. On the wall of duct 1, on either side of the longitudinal slit 2 in front of the reflecting plate 4, the spring-loaded guide plates 8 and 9 are arranged with vertical and horizontal movement, arranged parallel to the bottom wall of the duct 1. Lazes are made in the guide plates 8 and 9 ten.

The air distributor operates as follows.

Air from the main duct (not shown) is supplied to the upper part of the duct 1 and through the filter 3 enters the lower part of the duct 1, where it is partially cooled by convective heat exchange with the coil 6 and through the slot 2 enters the room. In this case, a part of the supply air with spring-loaded guide plates 8 and 9 is guided by laying streams on the bottom wall of the box 1.

Another part of the air passes through the gap between the spring-loaded guide plates 8 and 9 and is discharged into the working area of the room by means of the rotary elements of the reflecting plate 4. The direction of the air jets supplied to the working area of the room is determined by the position of the rotary elements of the reflecting plate 4. blowing the bottom wall of the duct 1 and supplying the required amount of air to the working area is established when adjusting the ventilation system by changing the width of the gap between the spring-loaded directions plates 8 and 9 and the distance between them and the bottom wall of box 1, which changes when plates 8 and 9 move. Placing two spring-loaded plates between the longitudinal slot of the box and turntable plates makes it possible to reduce the temperature of the bottom side of the box and thereby increase the efficiency of heat transfer that allows you to keep in

5, the room is comfortable at a higher room air temperature.
