[0003] The air conditioning in the computer room is controlled by a temperature detector (thermostat, etc.) installed in the air conditioning system, and when the thermostat detects an abnormal rise in the environmental temperature, it outputs an alarm to maintenance personnel. If the air conditioning equipment in operation is out of order, a maintenance person or the like operates the air conditioning equipment operation switching device to switch over to the backup air conditioning equipment. If backup air conditioning equipment was not available, computers would be shut down and the environment would have to wait for the temperature to return to normal.
