REGENERATIVE HEAT EXCHANGER WITH EVAPORATION COOLING Russian patent published in 2019 - IPC F24H8/00 F24F3/147 

FIELD: heating equipment.

SUBSTANCE: invention relates to heat engineering and can be used to increase efficiency of boilers and ventilation systems by means of deep heat regeneration due to evaporation cooling of wet emissions: outgoing flue gases of boilers or ventilation emissions. Proposed heat exchanger 1 has left and right regenerators 2 and 3 combined into unit 11, which consist of alternating multi-pass air heating channels 14 and layers of water-permeable structure (capillary-porous particles 20, grids 21 and their combinations 22) separated by vertical baffle 12 half-and-half. Regenerators 2 and 3 with the help of two-way valves 5 and 6 shutters 4 are periodically synchronously connected one from above to path 7 of supply of wet emissions, and the other from below is counter-current to channel 10 of air heated in channels 14.

EFFECT: higher efficiency of boiler 31 operation with provision of comfortable temperature and humidity mode in ventilated room.
