Abstract: A management device includes: storage unit which stores a known intake air temperature of a heating element, and a heat transfer characteristic of a cooling device; heat extraction amount calculation unit which calculates a heat extraction amount of the cooling device, by use of the refrigerant information input by the input means, and a cooling capacity of the refrigerant; and air volume calculation unit which calculates an air volume of air supplied to the cooling device, by applying the heat extraction amount to air volume dependence of the heat extraction amount, being derived by use of air volume dependence of a difference temperature between a temperature of the refrigerant and a temperature of exhaust air from the heating element, and the heat transfer characteristic, the air volume dependence of the difference temperature being derived by use of the intake air temperature, the power consumption, and the refrigerant information.
