Abstract:
1. An installation for cooling an electronic device provided in a room, comprising: an air conditioner having an air inlet for receiving air from the room and an air outlet for blowing cooling air to the room; an air conditioner return temperature detector adjacent to the air inlet of the air conditioner, for detecting a temperature of the air from the room; a rack accommodating the electronic device, the rack having an air inlet for receiving the cooling air from the air conditioner and an air outlet for exhausting air to the room; a rack exhaustion temperature detector adjacent to the air outlet of the rack, for detecting a temperature of air exhausting through the air outlet of the rack; an air conditioner blow temperature detector adjacent to the air outlet of the air conditioner, for detecting a temperature of air conditioner blow; a rack introduction temperature detector adjacent to the air inlet of the rack, for detecting a temperature of air introducing through the air inlet of the rack; and a controller for acquiring the temperature detected by the air conditioner return temperature detector, the rack exhaustion temperature detector, the air conditioner blow temperature detector and the rack introduction temperature detector, and controlling a quantity of the cooling air blown from the air outlet of the air conditioner; wherein the controller causes a decrease in the quantity of the cooling air when the temperature detected by the rack exhaustion temperature detector is larger than the temperature detected by the air conditioner return temperature detector so as to decrease a difference between the temperatures detected by the air conditioner blow temperature detector and the rack introduction temperature detector, and the controller causes an increase in the quantity of the cooling air when the temperature detected by the rack introduction temperature detector is larger than the temperature detected by the air conditioner blow temperature detector so as to decrease a difference between the temperatures detected by the air conditioner blow temperature detector and the rack introduction temperature detector.
