<P>PROBLEM TO BE SOLVED: To provide an air conditioning system having an air volume control mechanism, which is a self-actuated mechanism requiring no motor and does not blow off the air volume larger than a set air volume, and to reduce a frequency of the air volume control for facilitating maintenance. <P>SOLUTION: An air volume control apparatus is connected to the lower surface of a grid air inlet. The air volume control apparatus includes a box-shaped appliance frame opened in the upper and lower sides, and a float board is arranged inside the appliance frame, while a plurality of blade shafts are fixed to the upper face inside the appliance frame. To each of the blade shafts, a butterfly-shaped blade opening to the right and left is attached downward. The blade shaft and the blade are connected with each other in a hinge manner, and the blade can be opened and closed within a fixed angular range. Air for air conditioning is supplied from the lower side of the appliance frame. When the float board moves upward/downward according to a static pressure in the air volume control apparatus and the air volume and presses the respective blades from the lower side to open/close the blades, an air volume fed to the grid air inlet varies within a fixed range, and the air volume fed from the grid air inlet to a server room is regulated. <P>COPYRIGHT: (C)2012,JPO&INPIT |
