Description

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

The purpose of the invention is to increase the operational capabilities.

Figure 1 schematically shows the device section; figure 2 - section aa in figure 1 (with the application of the auxiliary air flow); on (tMr.4 - section B-B. in Fig. 1 (with air flow applied in summer operation mode of the installation; Fig. 5 - air cooler section; Fig. 6 schematically shows the device, cut in position for maintenance one of the sections.

The air cooler contains a regenerative evaporative air cooling (RKB) unit, including sections of the same type 1, an air distribution box 2 and connecting

rods 3,

Each section 1 contains a pallet 4,: packages of successively installed plates 5, one side of which is water-resistant and the other side is capillary-porous. In the case of sequential installation of the plates 5, four dry channels 6 (figures 2 and 3) and wet channels 7 are formed. Each section 1 is bounded by a shell 8, inside of which partitions 9 are made, and has guide surfaces 10 and fixing mechanisms 11, made, for example, in the form of clamps. Wet channels on the ends of the packages are closed with plugs 12

The partitions 9 serve as a dp for fastening the pallet 4 with a package of plates 5 to the shell 8, and also divide the space between the shell and the pallet with the package nftacTjiH on the cavity t3-18. Air distribution box 2 is divided by partitions into cavities 19, 20, 21 and 22 and has connections

In the winter mode of operation, outside air is supplied through nozzle 26 into the static pressure chamber formed by the cavity 22 of the junction box 2, together with the cavities 16 of sections 1, through the horizontal cavity 18 enters the wet channels 7, where it is heated and moistened by the heat of exhaust air from the room passing in this mode through the dry channels 6.

Exhaust room air is supplied to dry ducts 6 through nozzle 2 and a static pressure chamber formed by a cavity 20 and cavities 14. At the same time, it gives off heat to fresh air passing through moist ducts 7. Since the temperature of the air passing through wet channels, below the dew point of exhaust air, the water that condenses out into the sump is condensed out of the latter. The dried and cooled air
