LilA The invention relates to a technique of ventilation and air conditioning. The purpose of the invention is to increase the efficiency of the installation for indirectly evaporative air cooling. FIG. 1 is a schematic diagram of a plant for indirect evaporative cooling; in fig. 2 is a plan view of a unit for indirectly evaporative air cooling. The installation for indirectly evaporative air cooling comprises a housing 1 with a pallet 2 and with nozzles 3, 4 and 5, respectively, supplying the total air flow and discharging the main and auxiliary air flows. In the housing 1 there are plates 6, which in pairs form alternating channels 7 and 8 of the common and auxiliary air flows, with the plates 6 on the side of the channel 7 of the general air flow covered with a moisture-proof material (not shown), and on the side of the channel 8 of the auxiliary air flow - capillary porous material 9. The nozzles 3 for supplying the total air flow are installed at the ends 10 of the housing 1, and two nozzles 4 for removing the main air flow are located at the opposite ends 10 on top of the housing 1. The nozzles 5 are for diverting the auxiliary flow The air is installed in the middle part of the housing 1 at the same distance from its ends 10. The channels 7 of the total air flow are made along the entire length of the plates 6, and each channel 8 of the auxiliary air flow is connected to both adjacent channels 7 of the total air flow. Separating partitions 11 can be additionally installed in the channels 8 of the auxiliary air flow between the plates 6. At the place where the channels 7 and 8 of the common and auxiliary air flows communicate with the nozzle 4 for removing the main air flow, plugs 12 are installed. The installation for indirectly evaporative air cooling works as follows . The total air flow enters the device from two sides through the nozzles 3 for supplying the total air flow and, passing through the channels 7, is cooled at a constant cross-sectional content. At the end of the channel 7, the part of the total air flow comes out of the installation to the consumer through the nozzle 4 for removing the main air flow, and the remaining part enters the channels 8 of the auxiliary air flow, extracting heat from the total air flow, and in the middle part of the housing 1 through the nozzle 5 for exhaust an auxiliary air stream is emitted into the atmosphere. When the device is operating, a more optimal air flow pattern is organized, in which a flow pattern with maximum temperature pressure is implemented at the inlet of the total air flow into the device, and before the total air flow out of the anal channel 7, a counter current flow pattern allows the approximate temperature to be approached. air to its temperature dew points.
