The invention relates to air conditioning technology and can be used, in particular, with comfortable conditioning of the microclimate in the workplace area.

The purpose of the invention is to increase the efficiency of controlling the parameters of the conditioned air.

Fig. 1 is a schematic diagram of an air conditioning unit at the lower positions of the movable control elements of the air conditioner; Fig. 2 shows the same with the upper positions of the movable control elements; on fig.Z. - kinematic diagram of flexible coupling of control elements (the dotted line shows the upper position of the control elements); Fig. 4 shows the air conditioning unit of the air conditioning unit and the guide pipe of the additional air supply duct with the pivoting guide elements, top view.

The air conditioning unit contains (Fig. 1) a central air conditioner (not shown) communicated via duct 1 with an air conditioner-closet 2 located in the room, which is connected to a room (not shown) through the recirculation duct 3 with the heat exchanger 4 and through the inlet duct 5. .

Through the additional supply channel 6, the air conditioner closer 2 communicates with the indoor workplace (not shown).

The main and additional supply channels 5 and 6 have a single regulating element 7 in the form of a flap valve, and the recirculation channel 3 has a regulating element 8, which are interconnected by a flexible connection, for example, in the form of a drive shaft 9 with pulleys 10,11 and 12 and cable-block systems 13 and 14 consisting of cables 15 and 16 and blocks 17,18,19 and 20 with the possibility of providing simultaneous overlap by regulating elements 7 and 8 of the additional supply air and recirculation channels 6 and 3 and variable overlap - main and additional air supply als and 6. five.

The regulating element 8 is connected (fig.Z) through the cable 13 and blocks 17 and 18 to the pulleys 10 and 12, and the regulating element 7 through the cable 13 and blocks 19 and 20 to the pulley 11, and the ratio of the diameters of the pulleys 10,11 and 12 can be executed directly in proportion to the ratio of the lengths of movement of the regulating element 8, which ensures synchronization of the location of the regulating elements 7 and 8 in their extreme positions.

At the entrance of the air duct 1 to the air conditioner closer 2 there is a chamber 21 of primary air, communicated through

nozzles 22 with a mixing chamber 23. The regulating element 7 can be provided (Fig. 4) with pivoting guide elements 24.

Air conditioning unit

air works as follows. Fresh (primary) air is supplied from a central air conditioner (not shown) through duct 1 to primary air chamber 21, and from there, through nozzles 22, enters mixing chamber 23.

At the lower position of the regulating element 8 and the closed position of the additional supply channel 6 (Fig. 1), recirculated air does not enter the chamber 23 and the air from the central air conditioner enters the room through the supply channel 5.

With the upper position of the regulating element 8 and the open position of the additional supply channel 6 (Fig. 2), the recirculated air from the room passes through the heat exchanger 4, where it is processed (cooled or heated), mixed with the primary air, after which the air mixture is fed through additional supply channel 6 to the workplace.

By changing the position of the regulating element 7 it is possible

controlling the flow rate of air entering through the additional supply channel 6, its temperature (changing the ratio of the amounts of recirculation and primary air), the direction and speed of the discharge of the supply jet in the vertical plane at the workplace, and the direction and speed of the air outlet in the horizontal plane are adjustable guide elements 24.

Thanks to the ability to regulate air parameters,

the direction and speed of its supply jet creates the opportunity to create a local microclimate at the workplace, as well as air conditioning when the whole room is needed.
