Cooling apparatus, control method, and storage medium

A control method of a cooling apparatus including:

• an evaporator receiving exhaust heat of an electronic device;
• a condenser releasing the exhaust heat received by the evaporator;
• a heat exchanger receiving exhaust heat of the electronic device;
• a freezer releasing exhaust heat received by the heat exchanger and the evaporator, by circulating coolant between the condenser and the heat exchanger;
• a blower unit supplying a blast for cooling the electronic device to the electronic device;
• and
• control unit controlling operations of the blower unit and the freezer, the control method comprising:
• calculating power consumption of a blower unit, based on a rotational speed of the blower unit;
• calculating power consumption of the freezer, based on a calorific value of the electronic device, and a performance coefficient of the freezer;
• calculating an apparatus performance coefficient being a performance coefficient of an apparatus including the evaporator, the condenser, the heat exchanger, the freezer, and the blower unit, based on a calorific value of the electronic device, power consumption of the freezer, and power consumption of the blower unit;
• controlling a rotational speed of the blower unit, based on the apparatus performance coefficient;
• and
• controlling a first coolant temperature being a temperature of the coolant flowing from the freezer, based on the apparatus performance coefficient.

A storage medium storing a control program of a cooling apparatus including:

• an evaporator receiving exhaust heat of an electronic device;
• a condenser releasing the exhaust heat received by the evaporator;
• a heat exchanger receiving exhaust heat of the electronic device;
• a freezer releasing exhaust heat received by the heat exchanger and the evaporator, by circulating coolant between the condenser and the heat exchanger;
• a blower unit supplying a blast for cooling the electronic device to the electronic device;
• and
• control unit controlling operations of the blower unit and the freezer, the storage medium storing a control program that causes a computer to execute processing of:
• calculating power consumption of a blower unit, based on a rotational speed of the blower unit;
• calculating power consumption of the freezer, based on a calorific value of the electronic device, and a performance coefficient of the freezer;
• calculating an apparatus performance coefficient being a performance coefficient of an apparatus including the evaporator, the condenser, the heat exchanger, the freezer, and the blower unit, based on a calorific value of the electronic device, power consumption of the freezer, and power consumption of the blower unit;
• controlling a rotational speed of the blower unit, based on the apparatus performance coefficient;
• and
• controlling a first coolant temperature being a temperature of the coolant flowing from the freezer, based on the apparatus performance coefficient.
