Abstract

An air conditioner sucks air exhausted from an information processor, and cools down the sucked air. The air conditioner exhausts the cooled air. The air conditioner acquires a cooling state, determines whether a cooling capacity exceeds an upper limit value, and reduces the volume of exhaust air when it is determined that the cooling capacity exceeds the upper limit value. For example, the air conditioner calculates a thermal load as the cooling state by using the volume of exhaust air, a difference between the temperature of exhaust air and the temperature of suction air, and determines that the cooling capacity exceeds the upper limit value when the calculated thermal load exceeds a given threshold. The air conditioner measures the temperature of exhaust air, and determines that the cooling capacity exceeds the upper limit value when the measured temperature exceeds a set value.
