Control device, program, control method of refrigerator, and refrigerator

A control device that controls, in a refrigerator including a first storage compartment and a second storage compartment, a compressor and an in-refrigerator fan to circulate cool air in the refrigerator, the control device comprising:

• a controller that controls a rotational speed of each of the compressor and the in-refrigerator fan based on an outside air temperature of the refrigerator;
• and
• a calculator that calculates an average internal temperature of the second storage compartment during one cycle from when the compressor stops an operation until when the compressor stops a next operation;
• wherein
• the controller controls an operation and stoppage of the compressor based on an internal temperature of the first storage compartment and corrects the rotational speed of the in-refrigerator fan when the compressor operates during a next cycle based on a comparison result between the average internal temperature and a threshold.

A control method of controlling, in a refrigerator including a first storage compartment and a second storage compartment, a compressor and an in-refrigerator fan to circulate cool air in the refrigerator, the method comprising:

• a control process of causing a process core to control a rotational speed of each of the compressor and the in-refrigerator fan based on an outside air temperature of the refrigerator;
• and
• a calculation process of causing a process core to calculate an average internal temperature of the second storage compartment during one cycle from when the compressor stops an operation until when the compressor stops a next operation;
• wherein
• in the control process, the processor core controls an operation and stoppage of the compressor based on an internal temperature of the first storage compartment and corrects the rotational speed of the in-refrigerator fan when the compressor operates during a next cycle based on a comparison result between the average temperature and a threshold.
