The system is equipped with a water temperature detector that detects the temperature of the water circuit between In an air conditioning system that feedback-controls the temperature of a water circuit and controls the operation of a water heat source heat pump unit using a specified indoor temperature as a control target value, the indoor temperature is feedback-controlled. A temperature range and each allowable limit target value for each overload response for cooling operation and heating operation are set as control target values for indoor temperature, and the upper limit of the temperature range is set during cooling operation with the maximum output of the center heat pump unit. or when the lower limit of the temperature range is exceeded during heating operation with the maximum output of the center heat pump unit, the permissible limit target value is applied instead of the specified value as the indoor temperature control target value, and An air conditioning system characterized by comprising a control device that reduces and controls the amount of heat exchange of an air heat exchanger of a water heat source heat pump unit.
