Abstract: A modular data center includes a fan which creates a cooling wind by taking in outside air, electronic devices which takes in the cooling wind and to discharge an exhaust flow, a flow passage which guides a part of the exhaust flow to upstream of the fan, an opening-closing portion which opens and closes the flow passage, and a control unit which adjusts the cooling wind by controlling the fan, and thereby to cool a temperature of the electronic device to a specified temperature. The control unit closes the opening-closing portion when a first assumed value of power consumed by the fan is smaller than a current value of the power. The control unit opens the opening-closing portion when a second assumed value of the power consumed by the fan is smaller than the current value of the power.
