ENERGY-SAVING DEVICE FOR THE PREPARATION OF INLET AIR Russian patent published in 2019 - IPC F24F5/00 F24F7/00 

FIELD: construction.

SUBSTANCE: proposed invention can be used for preliminary heating and cooling of supply air in ventilation and air conditioning systems in winter and summer periods, respectively. Energy-saving device for preparation of supply air includes plate-type heat exchanger placed below level of soil freezing, consisting of slot channels arranged with slope towards air movement at some distance from each other in soil and connected by their edges on one side through slotted openings with air distributor, which hole at the ground surface level is connected to the intake cap, which side walls are perforated with vertical slots, and on other side of edge of slot channels are connected to air receiver, on central vertical axis of which there is vertical pipe, filled with transport wick, lower edge of pipe is below level of condensate in air receiver, and upper edge is passed through opening of cover and is connected to hole in pyramidal bottom of water-releasing cap, covered with grate of wick strips, connected to transport wick, side walls of the moisture-releasing cap are perforated with slots, and the side wall of the air cap is connected through the inlet air duct to the ventilation equipment, wherein air distributor is divided by horizontal partitions from top to bottom into intake, blind and collecting chambers, intake and collecting chambers are equipped with rectangular inlet and outlet vertical slots with flaps connected to several vertical slit heat exchangers located at angle of 90° relative to each other, bottom of collecting chamber of air distributor is connected by inclined cylindrical channel with bottom of air receiver.

EFFECT: higher efficiency of energy-saving device for inlet air preparation.
