ICT EQUIPMENT COOLING SYSTEM AND ICT EQUIPMENT COOLING METHOD

摘要

PROBLEM TO BE SOLVED: To prevent local hot spots in cold isles in ICT equipment rooms such as a server room, a communication equipment room, and a data center into which an ICT equipment cooling system by cold-warm air separation system.SOLUTION: An ICT equipment cooling system of the present invention comprises: an air conditioner supplying cold air for cooling ICT equipment to the ICT equipment, recovering warm air warmed by the ICT equipment, and cooling the warm air; a cold air passage to which the cold air is supplied from the air conditioner and which supplies the cold air to the ICT equipment, the cold air passage being physically separated from a passage of the warm air warmed by the ICT equipment and the cold air being spatially confined in the cold air passage; pressure measuring means attached into the cold air passage and measuring a pressure in the cold air passage; and control means connected to the pressure measuring means and the air conditioner, and controlling an air volume of the cold air supplied from the air conditioner to prevent the pressure in the cold air passage from becoming a negative pressure on the basis of an air volume of the cold air discharged from the air conditioner and pressure information from the pressure measuring means.
