PROBLEM TO BE SOLVED: To enable an ICT apparatus quickly and safely and achieve energy saving of an air conditioner.SOLUTION: A first calculation formula for estimating an inlet temperature of each ICT apparatus is calculated, a second calculation formula for estimating power consumption of each air conditioner is calculated, and a third calculation formula for estimating a change amount of the power consumption of the air conditioner is calculated using the first and second calculation formulas. A second load factor of each ICT apparatus in the third calculation formula is determined so that the power consumption of the air conditioner is made a minimum on the basis of the number of the ICT apparatuses necessary for processing a predetermined load. Providing that a first conditional expression for a condition that a value obtained by assigning a second blow temperature to the second calculation formula is a minimum is an object function and that a second conditional expression for a condition that a value obtained by assigning the second blow temperature and the second load factor of the ICT apparatus to the first calculation formula is not more than a first threshold is a constraint condition, the second blow temperature is calculated by means of mathematical planning. |
