Claim Text:
1. A container-type data center comprising: a container that includes an electronic device; a first fan that takes in outside air to the container and sends the taken-in outside air to the electronic device; a second fan that is built into the electronic device, cools down a heat-producing component provided in the electronic device, and rotates at a first rotation speed when a temperature of the heat-producing component is a first threshold or more, and rotates at a second rotation speed which is higher than the first rotation speed when the temperature of the heat-producing component is a second threshold or more which is higher than the first threshold; a differential pressure sensor that measures a differential pressure between a pressure in an intake air side and a pressure in an exhaust air side of the second fan; and a control unit that controls a rotation speed of the first fan and a rotation speed of the second fan based on a temperature of the heat-producing component and, when the second fan rotates at the first rotation speed or at the second rotation speed and a pressure in the exhaust air side is higher than a pressure in the intake air side, repeats controlling the rotation speed of the first fan so that the temperature of the heat-producing component increases by a predetermined temperature to make the pressure in the intake air side higher than the pressure in the exhaust air side, based on a measurement result of the differential pressure sensor.
