Air conditioning installation

Abstract

An installation for cooling an electronic device provided on a floor in a room includes an underfloor space below the floor; an air conditioner for sending air to the underfloor space; a first opening provided in the floor and adjacent to the electronic device, for sending air from the underfloor space to the room; and a second opening provided in the floor and adjacent to the air conditioner, the second opening being configured to cause the air pressure of the lower side of the second opening to be lower than the air pressure of the upper side of the second opening.

1 . An installation for cooling an electronic device provided on a floor in a room, comprising:
 an underfloor space below the floor;   an air conditioner for sending air to the underfloor space;   a first opening provided in the floor and adjacent to the electronic device, for sending air from the underfloor space to the room; and   a second opening provided in the floor and adjacent to the air conditioner, the second opening being configured to cause the air pressure of the lower side of the second opening to be lower than the air pressure of the upper side of the second opening.   
     
     
         2 . The installation according to  claim 1 , wherein the second opening is openable and closable, the installation further comprising:
 a sensor for detecting a direction of air getting through the second opening; and   a controller for enlarging the second opening when the sensor detects the direction of air from the room to the underfloor space, and reducing the second opening when the sensor detects the direction of air from the underfloor to the room.   
     
     
         3 . The installation according to  claim 1 , wherein the second opening is openable and closable, the installation further comprising:
 a sensor for detecting a pressure under the second opening in the underfloor space; and   a controller for enlarging the second opening when the sensor detects the pressure lower than a predetermined value, and reducing the second opening when the sensor detects the pressure equal to or higher than the predetermined value.   
     
     
         4 . The installation according to  claim 1 , wherein the air conditioner includes an air outlet for blowing air, the second opening being adjacent to the air outlet. 
     
     
         5 . The installation according to  claim 1 , wherein the flow rate of the air below the second opening is higher than that above the second opening.
