Description

FI.2

The invention relates to a technique for cooling and purifying air and can be used to obtain fresh moisture from atmospheric air.

The aim of the invention is to intensify the condensation process to obtain fresh moisture from atmospheric air.

FIG. 1 is a schematic diagram of an air treatment unit; in fig. 2 shows the interconnection of the main elements of the device in the zone of location of the internal vertical duct.

The air treatment unit contains coaxially arranged outer 1 and inner 2 vertical air ducts with the formation of annular 3 and inner 4 flow cavities, inclined heat pipes 5, evaporation sections 6 of which are installed in annular cavity 3, and upstream condenser sections 7 - in internal cavity 4, and placed in the annular cavity 3 under the heat pipes 5, the condensate collector 8 with the outlet channel 9

Air ducts 1 and 2 are connected by upper sections with the atmosphere, and heat pipes 5 have a developed external heat exchange surface. In the annular cavity 3 is air-permeable material 10 with the formation of radial flow channels 11.

In the lower part of the inner duct 2 is made bypass holes 12, through which the latter communicates with the lower portion of the outer duct 1.

The upper portion of the inner duct 2 communicates with the atmosphere through the deflector 13, the outer outer side of the outer duct 1 (preferably on the south side) and the sunscreens 14 and 15 are located above the upper portion of the outer duct, the latter of which are in a staggered spaced relative to each other dke.

The outer heat transfer surface of the heat pipes 5 is developed from the side of the annular flow cavity 3 can be made in the form of whiskers 16 evenly placed in an air-permeable material.

The internal vertical duct 2 can be insulated from the annular cavity 3 by means of thermal insulation (not shown).

The condensate collector 8 through the bypass channel 9 is in communication with the downstream tank 17.

The air treatment unit operates as follows.

Outside air through the upper portion of the outer vertical duct and through the staggered and offset relative to each other sunscreens 15 enters the annular flow cavity 3.

When air comes into contact with the air-permeable material 10, the mustache 16 and the evaporative sections 6 of the heat pipes 5, the air is cooled below its dew point temperature, as a result of which condensate released from the cooled air 8 forms in the condensate collector 8,

which then goes to the tank 17 via the diversion channel 9.

The cooled and dried air from the annular cavity through the flow channels 11 and the bypass holes 12 enters the internal cavity 4 of the duct 2.

The heat of condensation of moisture released from the air in the annular cavity 3 is transferred through the evaporation sections 6 of the heat pipes 5 to their working fluid, which passes into a vapor state and moves

Q inside the heat pipes 5 to their condenser sections 7 located in the inner cavity 4 of the duct 2,

Upon contact of the air duct 2 which has entered the internal cavity 4 and the cooled 5 and dried air with the condenser sections 7 of the heat pipes 5, the air is heated, which is then removed using the deflector 13 from the air duct 2 to the outside.

When cooling the working fluid of heat pipes 5 in the condenser sections 7

it condenses and returns

again in the downstream evaporative

6 heat pipe sections 5.

The location of the sunscreens 14 and 15 on the outer side of the duct 1 5 and above its upper portion contributes to a deeper cooling of the air in the annular flow cavity 3 of the outer duct 1.
