COMPRESSED AIR HEAT EXCHANGER, DEHUMIDIFICATION UNIT USING THIS HEAT EXCHANGER, AND DEHUMIDIFICATION SYSTEM EQUIPPED WITH DEHUMIDIFICATION UNIT Russian patent published in 2021 - IPC B01D53/26 F28D7/02 

FIELD: heat power engineering.

SUBSTANCE: group of inventions relates to a compressed air heat exchanger with a more effective channel system, a unit for humidification of compressed air using such a heat exchanger, and a humidification system equipped with such a humidification unit. Heat-exchange flow part 20 of the compressed air heat exchanger is formed by alternative winding of two (the first and the second ones) spiral heat-transfer walls 24 and 25 with a set gap between them around external periphery of cylindrical flow pipe 10 of main heat transfer channel 11 in the radial direction of flow pipe 10, in which, on main heat transfer channel 11, inside of it, cold source 3 is located. Inlet channel 21 and outlet channel 22 designed for introducing compressed air to flow pipe 10 and withdrawing compressed air from flow pipe 10 are formed alternatively in the radial direction by the gap between heat-transfer walls 24 and 25. Heat exchange is carried out between compressed air passing through channels 21 and compressed air passing through channels 22.

EFFECT: increase in the dehumidification efficiency.
