PURPOSE:To uniformize temperatures within a room and consequently improve the comfortability by a structure wherein a suction port and a blowoff port are arranged on the wall opposite to and within the same room as an heating equipment installed indoor at predetermined heights repectively so as to form a tubular forced circulation passage, the blowoff port of which is inclined to a floor surface with a predetermined angle. CONSTITUTION:The air circulating device 3, in which a fan 3a is contained and which provides with the suction port 3b arranged at the position having its height h1 of more than 1,500mm. from a floor surface 1a and with the blowing-off port 3c arranged at the position having its height h2 of 100-500mm., is formed on the wall opposite to the heating equipment 2 and the blowoff port 3c is inclinedly formed to the floor surface 1a with the inclination angle of 20-80 deg.C. Furthermore, the capacity of the circulating device 3 is set so that the rate of the air blown off out of the blowoff port 3c is rendered to be 3-10 times of the volume of the room per hour. In such a manner as mentioned above, the warm air in the upper part of the room circulates at proper speed in the room along the floor surface 1a. Consequently, the temperatures in the room can be uniformized and the comfortability can be improved. |
