PROBLEM TO BE SOLVED: To provide an efficient cooling system, which takes outside air in winter or the like to enhance cooling efficiency, and supplies cold air only to a cooling object which needs cooling without supplying cold air to an unnecessary object. SOLUTION: The cooling system comprises: an air conditioner provided with a heat exchange coil and needing no blowing fan; a first duct for guiding a first air flow sucked from the inside of the air conditioner; a second duct for guiding outside air as a second air flow; a discharge port for discharging air from the inside of a room; a closed space for holding a third air flow to pass the third air flow to the cooling object; and a circulating blowing fan which sends the third air flow to the closed space through the first duct. The second duct is connected to the first duct so as to mix the second air flow by the negative pressure of the first air flow, whereby the third air flow is generated. The third air flow is passed through the closed space and the cooling object with a positive pressure after passed through the circulating blowing fan, raised in temperature by cooling the cooling object, and blown into the room storing the cooling object.
