VIBRATIONPROOF RACK BASE FOR AIR CONDITIONER

PURPOSE:To allow the air for air conditioning to flow under a floor without carrying dusts by arranging a rack base upper frame through a vibrationproof device on a rack base lower frame installed under a floor, forming an opened port connected to the undersurface blow-out port of an air conditioner equipment, on the upper frame, and connecting an opened port formed on the side between the upper and lower frames under the floor through a guide. CONSTITUTION:A rack base lower frame 4 installed on a foundation surface 3 under a floor, and a rack base upper frame 10 is installed in adjustment with a floor surface 1 through a vibrationproof device 5. Air conditioner equipment 2 is installed on the upper frame 10, and an undersurface air blow-out port 6 is allowed to communicate with an upper surface opened port 7 on the rack base upper frame 10. Further, a guide (duct) 11 for the communication between the upper surface opened port 7 and an underfloor blow-out port 8 opened on the side surface between the upper frame 10 and the lower frame 4 is installed. Accordingly, the air blown out from the undersurface of the air conditioner 2 flows as laminar flow along the guide 11, and is introduced under the floor quietly without carrying the dusts on the periphery.
