ethod of combined ventilation and heating of production, office and living rooms // 2320936
FIELD: mechanical engineering; ventilation and heating and heating systems.SUBSTANCE: plenum fresh air gets into room through intake air duct according to set rates. Waste air is drawn out along air ducts by means of exhaust fan through exhaust air duct. Intake and air ducts are furnished with recirculating valves to regulate flow of air taken from outside or from room. Plenum microprocessor control unit controls operation of recirculating valves basing on concentration of carbon dioxide in air by means of carbon dioxide sensor and depending on quality of air in room, said microprocessor control unit changes over recirculating valves from plenum to recirculation, i.e. to pass air through recirculation air duct. Further on air passing through filter and delivery fan gets into heating and intake chamber where it is heated to +20°C. Efficiency of heating is attained by increasing time of air passing in heating zone. Plenum microprocessor control unit switches on heating at the moment when air is taken from outside at below zero temperature. At recirculation conditions, heating and intake chamber is kept switched off, without affecting concentration of carbon dioxide in air, which is economically effective. Ventilating air ducts are not heated as they pass to required place of air getting into room, as air in room is +20°C and in ventilating duct is also +20°C. air before getting out in required place of room is heated by channel heater which heats coming out air to +43°C which is heating system. Said channel heater is controlled by temperature microprocessor control unit by means of temperature transmitter which switches ON and OFF channel heater depending on preset temperature in room.EFFECT: provision of required microclimate in room at minimum energy consumption.1 dwg
