Description

(54) DEVICE FOR HEAT AND WATER TREATMENT The invention relates to the technique of air conditioning and ventilation; . Devices for heat and humid air treatment are known, comprising a housing with inlet and outlet air nozzles and a pallet, located in a housing two Rusas with a regular nozzle, between which an inclined partition is installed, and a water distributor ij. The disadvantage of these devices is the inability to heat the air with a negative temperature due to frosting of the nozzle. The purpose of the invention is to provide for heating air with negative temperatures. The goal is achieved by the fact that the inlet is located in the upper part of the body and is provided with inclined walls forming side channels with it, and the nozzles are located in the body with the formation of the AIR bypass channel, and control valves are installed in all channels, the partition wall is perforated, and the water distributor is equipped with a tray . FIG. 1 shows a device for heat and moisture treatment, longitudinal section; FIG. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. 1. The device for heat and humidity treatment of air comprises a housing I with inlet and outlet air nozzles 2 and 3 and a pallet 4, located in the housing two rusas of a regular nozzle 5 and 6, between which an inclined partition 7 is installed, and a water distributor 8. The inlet nozzle is located in the upper part of the body and is provided with inclined walls 9, forming side channels 10 with it, and nozzles 5 and 6 are located in the body with the formation of a bypass channel 11, and control valves 12, 13, and 14 are installed in all channels

the partition 7 is perforated, and the water distributor is equipped with a tray 15,

The device works as follows.

The pressurized air flows to the water distributor 8, which, under the action of reactive force, begins to rotate, which contributes to the uniform irrigation of the nozzle. Water flows through the nozzle 5 on the perforated partition 7 and then on the nozzle biv pallet 4.

Air is drawn through the nozzle 5 from above, as well as from the ends, where it enters through the valves 13 and 14 and the side channels 10. A part of the air is drawn through the valve 12 of the bypass channel 1I, the nozzle 5.

The mixture of outside air and the air that has passed through the nozzle 5 is then drawn through the nozzle 6 from bottom to top. Tray 15 is located above the perimeter of the nozzle 5, and all the peripheral water flows into it, not directly on the nozzle.

The water collected in the tray is used for additional irrigation of the peripheral part of the nozzle 5,

This constructive implementation of the device allows processing

Ib it air with negative temperatures,
