  • Patent number: 9433122
    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.

  • Patent number: 9078377
    Abstract: An air volume control device determines whether or not a cooling capacity of an electronic device fulfills a predetermined cooling capacity. Then, if it is determined that the cooling capacity of the electronic device is failing to fulfill the predetermined cooling capacity, the air volume control device decreases the number of revolutions of a fan for cooling the electronic device. For example, the air volume control device compares a temperature of a heating element provided in the electronic device before a change in the number of revolutions of the fan with that after the change in the number of revolutions of the fan. If the temperature of the heating element is increased when the number of revolutions of the fan is increased, the air volume control device determines that the cooling capacity of the electronic device is failing to fulfill the predetermined cooling capacity.
