PURPOSE:To raise the temperature of air in a space by heating it by lessening the temperature difference in the vertical direction by a method in which an air blower is built in a vertical cylinder, and air is blown into the space from below and blown out toward necessary direction from the sideward direction in the upper part. CONSTITUTION:A vertical cylinder 1 is supported by legs or wheels in such a way as to enable a necessary lower air suction area to be kept, and an air blower to send air from below to above is attached to the inside of the cylinder 1. A dust collecting filer 7 is attached to the lower part of the cylinder 1 as needed. When a power source switch 3 is turned on, an air blower 2 is operated, and the air in the lower part is sucked up, flowed toward the upper sideward blow-out port 8 as shown by the direction of small arrow, and mixed and circulated orderly. A high-temperature side temperature sensor 6 is provided to the upper part, and a low-temperature side temperature sensor 5 is also provided to the lower part. When a temperature difference occurs, a temperature difference sensor is operated, and the air blower 2 is operated and stopped even automatically as needed. The vertical temperature difference and uneven temperature distribution can thus be eliminated and expensive improvement cost can be avoided. |
