PROBLEM TO BE SOLVED: To provide an operation control method for a cold/hot water pump in an air conditioning facility suppressing the useless power consumption of a driving motor as a result of supplying the flow of cold/hot water corresponding to the variation of required energy consumption on the load side by controlling not only the operating state of a heat source but also the rotating speed of the driving motor for the cold/hot water pump by the temperature of cold/hot water. SOLUTION: When the heat source 1 is in heating/cooling operation to set cold/hot water within a set temperature range, the driving motor 10a for the cold/hot water pump 10 for feeding cold/hot water from the heat source to an indoor unit is operated at the rotating speed N1 initially set by a rotation control means, and when the operation of the heat source 1 is stopped by detecting the cold/hot water to be within the set temperature range, the driving motor 10a for the cold/hot water pump 10 is operated until the cold/hot water reaches an optionally-set set temperature P1, at the rotating speed N2 computed by the rotation control means from various conditions at a point of time when the heat source stops heating/cooling operation.
