ENERGY-SAVING INLET AIR PREPARATION SYSTEM Russian patent published in 2018 - IPC F24F5/00 

FIELD: ventilation.

SUBSTANCE: energy-saving inlet air preparation system, containing the ventilation chamber, in which a valve, a fan, an air heater, a central air conditioner are placed, in front of which a drop catcher and a heat exchanger are arranged, placed below the level of soil freezing and consisting of heatexchanger tubes placed at a certain distance from each other in the soil, with the sloping towards the air movement and united by their edges from one side through the holes with the distribution air box, representing a rectangular vertical box with a pyramidal cover, the hole of which at ground level is connected to the inlet cap, side walls of which are perforated by vertical slits, and on the other side the edges of heatexchanger tubes are connected through holes with foster air box, representing a rectangular vertical box with a pyramidal cover and pyramid bottom, a hole of which at ground level is connected through the upper edge of tee with moisture eliminating cap, on the vertical axis of foster air box vertical tube is installed, filled with wick, the lower edge of which is below the level of condensate in a pyramidal bottom, and the top edge is connected through the hole with the bottom of moisture eliminating cap, on the surface of which a layer of wick is laid, connected to the wick of vertical tube. Wherein the heatexchanger tube heat exchanger are made finned cast, distribution and foster air boxes are made of reinforced concrete and moister eliminating cap is fitted with a deflector.

EFFECT: increase of reliability and efficiency of energy-saving inlet air preparation system.
