PROBLEM TO BE SOLVED: To provide a method of issuing a temperature difference rise warning capable of responding to rise in seawater temperature when the unexpected rise in the seawater temperature due to a natural phenomenon etc. is detected and of promptly issuing the temperature difference rise warning.SOLUTION: The method of issuing the temperature difference rise warning includes: a temperature measurement monitoring process of measuring the temperature of seawater at a water inlet 12 and detecting a case where the temperature of the seawater exceeds a predetermined reference value as the temperature rise; a temperature difference prediction calculating process of predicting and calculating a difference between the seawater temperature at a water outlet 16 after predetermined time passes and the seawater temperature at the water inlet 12, when the temperature rise is detected; and a temperature difference rise warning issuing process of issuing the temperature difference rise warning when the temperature difference predicted and calculated in the temperature difference prediction calculating process exceeds a preset value. In the method, before the seawater temperature difference between the water inlet 12 and the water outlet 16 is actually raised, load suppression of a condenser to prevent the rise can be promptly performed. |
