1. An inference circuit configured to obtain an inference value of a time required to melt frost for defrosting temperature information representing a temperature of an outdoor-side heat exchanger included by in an outdoor unit of an air-conditioning apparatus or a state of change in the temperature,
wherein the time required to melt frost is a period during which frost deposited on the outdoor-side heat exchanger is melted by refrigerant flowing through a refrigerant pipe of the outdoor-side heat exchanger and the temperature of the outdoor-side heat exchanger is stable within a first range, and
wherein the inference circuit comprises:
a first data acquisition circuit configured to acquire the defrosting temperature information of the air-conditioning apparatus; and
an inference circuit configured to, by using a trained model configured to infer the time required to melt frost from the defrosting temperature information and in accordance with the defrosting temperature information acquired by the first data acquisition circuit, obtain the inference value of the time required to melt frost for the defrosting temperature information.
