The invention relates to a technique of ventilation and air conditioning.

The purpose of the invention is to increase the efficiency of air cooling and simplify the assembly technology.

Fig. 1 is a schematic diagram of an installation for indirectly evaporative air cooling, Fig. 2 shows a section AA in Fig. 1, Fig. 3 shows a section B-B in Fig. 1, Fig. 4 shows a section B-B in Fig. 1, Fig. 5 is a section view of GG in Fig. 1, Fig. 6 is a section D of D in Fig. 2, Fig. 7 is a view E in Fig. 4, Fig. 8 is a section of WF in Fig. 2.

The installation for indirectly evaporative air cooling comprises a housing 1 with an inlet 2 of the total air flow and outlets of the main 3 and auxiliary 4 air streams, in which a package 5 of horizontal plates 6 is located with openings 7 located above each other in their middle part

Plates 6 are made of a moisture-proof material with a capillary-porous coating 8 on one of the sides with the formation of alternating between dry 9 and wet 10 channels of common and auxiliary air flows communicated with the corresponding nozzles 2-4

Pipe water distributor 11 has a flange 12 with a bayonet wrench 13 installed on it with a water fitting 14 and located in openings 17 of plates 6 made with radially located water distributors 11 with water grooves 15 communicated with the outlet 16 of the water distributor 11, which are located in the planes of the wet channels 10

One of two rows of arranged plates 6 is made on the side of the dry channel 9 with notches 17 and 18 and has a window 19 for the passage of the auxiliary air flow and on both sides of the projections 20 and 21, and the other plate 6 has on the side of the wet channel 10 projections 22 s cutout 23

The bayonet key 13 contacts the body 1

The housing 1 in the lower and upper parts can be made with clamping plates 24 and 25

The lower clamping plate 24 may be provided with a threaded rod 26, and the water distributor 11 in the lower part may be provided with a threaded portion 27 in which the rod 26 is located

The installation works as follows

The fan supplies the total air flow through the inlet 2 to the dry ducts 9, which is cooled as it passes through the latter without changing the moisture content.

At the outlet of the dry channels 9, the cooled total air flow is divided into the main and auxiliary air flows.

The main air flow through the outlet pipe 3 is supplied to the consumer, and the auxiliary stream through the window 19 enters the wet channels 10

When passing through the humid channels 10, the auxiliary air stream draws heat from the total air flow passing through the dry channels 9 while evaporating the liquid in the wet channels 10 and then is vented to the atmosphere

The capillary-porous coating 8 is moistened by supplying water through the outlet openings 16 and the water grooves 15

The use of the bayonet key 13 during assembly by turning it to a certain angle helps simplify the assembly (disassembly) technology
