PROBLEM TO BE SOLVED: To provide a cold/hot water control method for an air conditioning system using a local cold/hot water pump in each of air conditioners and to be operated with the maximum energy efficiency over the whole of the system in consideration of power consumption over the whole of the air conditioning system. SOLUTION: In the cold/hot water control method for the air conditioning system provided with a plurality of secondary equipment 1 and a plurality of secondary cold/hot water local pumps 16, a cold/hot heat source machine 8, a primary cold/hot water pump 18, and a bypass pipe 17 provided between a cold/hot water supply pipe 3a and a cold/hot water circulation pipe 3b, power consumption of each of the local pumps 16, the cold/hot heat source machine 8 and the primary cold/hot water pump 18 are added to compute system power consumption. Total flow of the secondary equipment 1 side cold/hot water is obtained through the bypass pipe 17 and secondary calorie is computed on the basis of a temperature difference between the cold/hot water supply pipe 3a and the cold/hot water circulation pipe 3b, and system COP is computed by dividing the secondary calorie by the system power consumption, and outlet temperature of the cold/hot heat source machine 8 is set to obtain the maximum system COP.
