The invention relates to the field of ventilation and air-conditioning.

The invention is a decrease in the moisture content of the treated air during the warm period of the year.

The drawing shows a schematic diagram of the vcTponcTna for implementing the air treatment method.

The device for implementing the air treatment method comprises nepnvio air cooling stage 1 with alternating channels to T of the common and auxiliary air streams, 4 inlet air inlet pipe and outlet pipes S and 6 of the pre-cooled, mainstream air flow and secondary flow of air iyv , i Channels and 3 are separated by a moisture-proof heat-exchanging surface 7 wetted from the side 3 of the auxiliary air flow.

The outlet nozzle 5 of the main air flow through the channel 8 communicates with the inlet nozzle Q of the main flow of the second stage air 10 of the cooling air with alternating channels 11 and 1 base and more about air flows with a separate surface 13. I lnaly 11 main flow air "irez outlet 1 & communicated with the consumer (not shown), canapes 1 additional air flow through the inlet and outlet nozzles 1 S and 16 with the atmosphere.

A device for implementing the air treatment method works as follows.

The flow of outside air through inlet A is directed to channels 2 towards the dry side of the tag-exchange surface 7, where it indirectly evaporates in the limit to the dew point temperature of the outside air. Then, the depleted signal is divided into auxiliary and main streams.

The auxiliary stream of air is directed to the channels 3 in countercurrent for indirectly evaporative cooling of the stream of outside air and then vented to the atmosphere through pipe 6

The main air flow is directed through the outlet nozzle S, channel 8 and the inlet nozzle H into the channels 11, and into the channels 1. at the same time through the inlet nozzle 1S an additional stream is supplied — the flow of outside air.

The heat exchange of the main and additional flows is carried out simultaneously with the mass exchange through the heat exchange moisture-permeable surface 13.

After the heat and mass transfer, the cooled main stream through outlet 5 of the branch} - 14 is supplied to the consumer, and the additional stream through the outlet 16 is vented to the atmosphere.

Claims (1)

1. Air treatment method, including 1 Phylium indirect evaporative cooling of the outside air flow, dividing it into auxiliary and main streams, subsequent supply of auxiliary flow along the countercurrent PL of indirectly evaporative cooling of the outdoor air and then o1: ln atmosphere, and the main TIC of the eye - for heat exchange with an additional g-current of air through heat exchange - KV, the surface, while one of the fluxes of the xc streams is then passed to the consumer, and the other is transferred to the atmosphere, the difference is that, with a view to sn During the warm period of the year, the moisture content of the extracted air, the heat exchanger osnon-o and the additional 1 outflows are carried out simultaneously with the mass exchange through the tetra-exchange rjjnronpfi-b; 7iaeMyK) surface, and an additional stream is discharged into the tmos-6sru, in which the outside air is used. . The method according to claim 1, of tl and h a-p c and t h in that the additional flow before the heat and mass transfer from the fire. The air flow is heated.
