Abstract
An air conditioning system includes: a heat source unit; an indoor unit; a water circuit configured by connecting a supply pipe and a return pipe; a flow rate adjusting valve provided in the water circuit; a supply air temperature control unit configured to adjust a flow rate of the flow rate adjusting valve; a pump provided in the water circuit; a pump controller configured to control a rotation speed of the pump; a return water temperature sensor; a supply water temperature sensor; a supply water temperature control unit; and a target supply water temperature updating unit configured to change a target supply water temperature to which a supply water temperature detected by the supply water temperature sensor is to reach based on a temperature difference between a return water temperature detected by the return water temperature sensor and the supply water temperature.
