Abstract
Provided are an air conditioning plant control method by which an air conditioning plant can be operated in a most desirable state, and an air conditioning plant so controlled. An air conditioning plant is controlled, which has at least one air conditioner, a refrigerating machine supplying cold water to the air conditioner and a cooling tower supplying cooling water to the refrigerating machine. Within an extent satisfying set conditions of air conditioning, setpoints of the draft temperature of the at least one air conditioner, the cold water temperature of the refrigerating machine and the temperature of cooling water from the cooling tower are altered and optimized so as to minimize energy consumption, operating cost or carbon dioxide emission of the air conditioning plant.
