Modular data center

A modular data center comprising:

• a structure provided with an intake port and an exhaust port, the ports being connected to outside;
• a first shutter provided to the intake port, and made openable and closable;
• a second shutter provided to the exhaust port, and made openable and closable;
• a rack disposed in the structure and configured to house an electronic device;
• a blower device capable of switching a flowing direction of air, the blower device being disposed in the structure and configured to feed the air into the rack;
• a first space provided between the first shutter and the rack;
• a second space provided on an opposite side of the rack from the first space;
• a third space provided between the second space and the second shutter;
• a fourth space located adjacent to the second space and the third space, and housing a moisture absorbent inside;
• a third shutter provided between the second space and the third space, and made openable and closable;
• a fourth shutter provided between the second space and the fourth space, and made openable and closable;
• a fifth shutter provided between the third space and the fourth space, and made openable and closable;
• an in-rack temperature detector configured to detect a temperature inside the rack;
• a dew-point temperature detector configured to detect a dew-point temperature of outside air;
• and
• a controller configured to receive signals inputted from the in-rack temperature detector and the dew-point temperature detector, and to control the first shutter, the second shutter, the third shutter, the fourth shutter, the fifth shutter, and the blower device.
