外気利用型冷却システム
Document Type and Number:
Japanese Patent JP6660727
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an outside air utilization type cooling system capable of keeping an air balance between an outside air intake amount and a discharged air amount even if the outside air intake amount of an outside air fan is varied and realizing a cooling air conditioning fulfilling a design specification.SOLUTION: An outside air utilization type cooling system 10A comprises outside air fans 18a, 18b for supplying outside air to a first machine chamber 14; air supply fans 20a, 20b for supplying air from the machine chamber 14 to a server chamber 13; discharging fans 21a, 21b for discharging hot air from the server chamber 13 to outside; a chamber pressure detecting part 22 for detecting chamber pressure of the machine chamber 14; a discharged air amount first adjustment means for increasing a discharged air amount of the discharging fans 21a, 21b when a differential pressure between a chamber pressure detected by the chamber pressure detecting part 22 and a reference pressure for measuring the differential pressure exceeds a set pressure; and a discharged air amount second adjustment means for decreasing a discharged air amount of the discharging fans 21a, 21b when a differential pressure between a chamber pressure and a reference pressure for measuring the differential pressure becomes less than a set pressure.SELECTED DRAWING: Figure 1
