PROCEDURE FOR AIR VENTILATION AND CONDITIONING AND DEVICE FOR ITS IMPLEMENTATION (VERSIONS) Russian patent published in 2011 - IPC F24F3/147 F24F12/00 

FIELD: power engineering.

SUBSTANCE: there is performed regenerative heat exchange between warm and cold air in zone of heat exchange. In the zone of heat exchange flows of cold and warm air leaving air ducts are transferred in mutually opposite directions without mixing flows of warm and cold air. Transfer of amount of heat is performed by changing velocity of warm air motion. Upon warm air cooling to required temperature cooled air is supplied into a cooled room. The device consists of a rotating regenerator, one working cavity of which is communicated with air ducts for cold air. The air ducts are intercommunicated through a working cavity of the regenerator. The second working cavity of the regenerator is communicated with air ducts for warm air. They are intercommunicated via another working cavity of the regenerator. The air ducts for warm air are communicated with space or a closed cooled room and form a closed circuit of circulation of cooled warm air.

EFFECT: upgraded accuracy of control of cooling modes.
