Prediction apparatus, refrigeration system, prediction method and prediction program

A prediction method of a prediction apparatus for outputting information for controlling a start timing of a defrosting operation, in a case where the defrosting operation is started on a heat exchanger functioning as a heat absorber, the defrosting operation being performed by a refrigerator including a refrigerant circuit in which a refrigerant circulates, the refrigerant circuit including a compressor, a radiator, an expansion valve, and the heat absorber that are annularly connected, the prediction method comprising:

• a procedure of inputting operation data of a current time in the refrigerator into a learned model, in a case where the learned model is generated based on learning data obtained by classifying a history of past operation data of the refrigerator into a plurality of groups by clustering and assigning, to each of the plurality of groups, data indicating presence or absence of frost formation on the heat exchanger;
• and
• a procedure of outputting information indicating presence or absence of frost formation on the heat exchanger predicted by the learned model.

A non-transitory computer-readable recording medium storing a prediction program that causes a computer to execute a process performed in a prediction apparatus, the prediction apparatus being for outputting information for controlling a start timing of a defrosting operation, in a case where the defrosting operation is started on a heat exchanger functioning as a heat absorber, the defrosting operation being performed by a refrigerator including a refrigerant circuit in which a refrigerant circulates, the refrigerant circuit including a compressor, a radiator, an expansion valve, and the heat absorber that are annularly connected, the process comprising:
