PROBLEM TO BE SOLVED: To reduce energy consumption of a heat source water pump and to improve coefficient of performance of an air conditioning system as a whole, in the air conditioning system comprising a water heat source multi-type heat pump system. SOLUTION: In this air conditioning system 1 comprising the water heat source multi-type heat pump system 10, and the water source water pump 52 disposed in a flow channel for supplying the heat source water to the water heat source multi-type heat pump system 10 and variably controlling the supply of heat source water, a rotational frequency ratio of a compressing device 14 is acquired, an inlet temperature Ti as a water temperature of the heat source water at a heat source water inlet is acquired, a target temperature To' of an outlet temperature To as the water temperature of the heat source water at an outlet of the heat source water is calculated on the basis of the rotational frequency ratio and the inlet temperature Ti, and the supply of heat source water by the heat source water pump 52 is controlled to control the outlet temperature To to the target temperature To' while applying the target temperature To' as a target.
