[Solution] The temperature management system includes: a first temperature detection unit 32 configured to detect a temperature of a heat generation component 14a in an electronic device 14; a cooling apparatus 12 configured to circulate air in the electronic device 14 and to cool the heat generation component 14a; a second temperature detection unit 33 configured to detect a temperature of air flowing in the electronic device 14; a parameter setting unit 31 configured to set a target value of the temperature of the heat generation component 14a; and a control unit 30. The control unit 30 calculates a predicted value of a future temperature of the heat generation component 14a based on the outputs of the first temperature detection unit 32 and the second temperature detection unit 33, and the power consumption of the electronic device 14, and determines a manipulated variable of the cooling apparatus 12 based on the predicted value and the target value.

[Problem] To achieve low power consumption while preventing electronic devices from excessive cooling in a modular data center and a controlling method of a modular data center. [Solution] A modular data center includes a fan 3a which creates a cooling wind B from outside air A, an electronic device 6 which discharges an exhaust flow E created from the taken-in cooling wind B, a flow passage L which guides part of the exhaust flow E to upstream of the fan 3a, an opening-closing portion 5 which opens and closes the flow passage L, and a control unit 20 which adjusts an air volume of the cooling wind B. The control unit 20 closes the opening-closing portion 5 when a first assumed value P 1 of power consumed by the fan 3a, which is assumed to be consumed in the case of bringing the temperature of the electronic device 6 to a specified temperature T s while closing the opening-closing portion 5, is smaller than a current value P 0 of the power. The control unit 20 opens the opening-closing portion 5 when a second assumed value P 2 of the power consumed by the fan 3a, which is assumed to be consumed in the case of bringing the temperature of each electronic device 6 to the specified temperature T s while opening the opening-closing portion 5, is smaller than the current value P 0 of the power.
