FIELD: air conditioning equipment, particularly heating and/or venting devices for chemical, metallurgical, welding, foundry and galvanic plants characterized by significant air pollution and demanding large venting air rate, as for residential building ventilation and/or heating. ^ SUBSTANCE: device comprises heating chamber to heat air exiting from room, regenerative vessels, pressure air duct having pressure blower and exhaust air duct having exhaust fan. The heating chamber comprises heater. Regenerative vessels have gates for alternate communication of each regenerative vessel with ambient space and pressure air duct, as well as with heating chamber and ambient space. Exhaust air duct us communicated with heating chamber. Method for device operation involves alternately shifting gates for each regenerative vessel communication with ambient space and pressure air channel, as well as with heating chamber and ambient space. ^ EFFECT: decreased power inputs due to low-potential heat utilization. ^ 9 cl, 1 dwg |
