PROBLEM TO BE SOLVED: To provide an outside air cooling system control method capable of performing cooling operation for a longer time than a present state by the same input calorific value, by cooling by an air conditioner, by continuing the introduction of outside air, due to being able to reduce a required input calorific value on the side for cooling the outside air by the air conditioner than cooling recirculating air by the air conditioner, when the outside air temperature is the recirculating air temperature or less. SOLUTION: This outside air cooling system includes a recirculating air duct motor damper for adjustably limiting a recirculating air temperature sensor and a recirculating air intake quantity, an outside air intake motor damper for adjustably limiting an outside air temperature sensor and an outside air intake, and an air-conditioning control means having a cold water two way valve for adjusting the circulation of cold water circulating in a heat exchanger and an input part for inputting the indoor preset temperature, communicably connected to the outside air temperature sensor and the recirculating air temperature sensor and controllably connected with an outside air intake motor damper and a recirculating air duct motor damper.
