Abstract

The invention relates to an air conditioning installation and the control method. An installation for cooling an electronic device includes an air conditioner having an air outlet for blowing cooling air to a room; a first detector adjacent to the air outlet of the air conditioner, for detecting a temperature of the cooling air; 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 second detector adjacent to the air inlet of the rack, for detecting a temperature of air received through the air inlet of the rack; and a controller for acquiring the temperatures detected by the first and the second detectors, and controlling a quantity of the cooling air blown from the air outlet of the air conditioner so as to decrease a difference between the temperatures detected by the first and the second detectors.

Description

Technical field [0001] The embodiments discussed herein relate to air conditioning facilities and air conditioning control methods that control the amount of air from an air conditioner. Background technique [0002] In recent years, cabinets have been installed in spaces called data centers or computer rooms. IT equipment such as servers and network equipment is installed in the cabinet. Since IT equipment includes functional components, such as a CPU, the IT equipment uses electricity and generates heat. The temperature of the IT equipment needs to be maintained at or below a certain temperature to ensure normal operation. Therefore, air conditioning facilities are used. The air conditioning facility cools the IT equipment in the cabinet by blowing cold air from the air conditioner. [0003] The air circulation of the air conditioning facility will be described below. The air conditioner blows cold air to provide cold air to the cabinet. Fans embedded in the IT equipment in...
