PROBLEM TO BE SOLVED: To reduce the total of consumption power of fan power of a cooling tower and consumption power of pump power when cooling by using free cooling of the cooling tower. SOLUTION: The cooling system is equipped with: a simulator 51 for simulating obtaining a total value of consumption power of a cooling tower fan 10 and pumps 2, 4 by using at least a cooling water temperature of a cooling tower outlet 1a and a cold water temperature of a first heat exchanger outlet 11a as input values; an optimal value obtaining part 52 for changing the input values of the cooling water temperature and the cold water temperature and inputting them in the simulator 51, and obtaining the cooling water temperature and the cold water temperature as optimal values in which the total value of the consumption power becomes minimum from the result of the simulation; and a control value setting part 53 for setting the actual cooling water temperature and the cold water temperature to the optimal values obtained by the optimal value obtaining part 52.
