AIR HEAT CURTAIN Russian patent published in 2010 - IPC F24F9/00 

FIELD: power engineering.

SUBSTANCE: curtain is designed for development of favourable sanitary-hygienic conditions in production premises or at individual work places. Curtain comprises microprocessor master controller arranged in a separate unit, to which the following components are connected - frequency controller of fan electric motor, fan, heater capacity controller, heater, arranged in a separate unit, sensor of temperature installed inside room, and air distributor. Inside and outside the room along height of door opening there are pressure sensors installed, being equipped with recorders of pressure differences and connected parallel to microprocessor master controller, which obtains initial data from them to control air supply to air distributor.

EFFECT: reduced consumption of thermal and electric energy as a result of monitoring of air exchange parametres and accurate control of parametres as air exchange conditions through door opening change, and design simplification.
