<p>PURPOSE:To utilize the radiant heat energy of an air blower motor as a heat source by alternately performing the heating of exhaust air in an enclosed room under a reduced pressure and the suction and supply of air by using a system in which when the temperature of an enclosed room is raised to more than a fixed temperature, the open air is sucked into the enclosed room, heated by the radiant heat of the air blower motor and an auxiliary heater, and supplied. CONSTITUTION:An air-tight room 3 is provided by installing a partition plate 2 in a device body 1, and an air supply duct 5 is projectionally provided outwards from the back side on the lower end of an air blower 4 set in the central part of the partition plate 2 and opened or closed by a shutter 6. An air suction port 10 in the frontal upper position of the body 1 is opened or closed by a shutter 6'. A differential pressure fan 15 is provided connectedly to an exhaust duct 13 set on the ceiling of the air-tight room 3 and an exhaust port 14 provided on the side of the body 1, a ventilation control plate 16 is provided on the suction port of the duct 13, and an auxiliary heater 20 consisting of a combustion cylinder 17, a burner 18, a stack 19, etc., is provided in the air-tight room 3 in parallel with the exhaust duct 13.</p> |
