REFRIGERATOR

WIPO Patent Application WO/2022/013926

A1

This refrigerator is supplied with power from a power supply system that includes a power generation device utilizing natural energy, the refrigerator comprising: a communication device which communicates with a server that predicts a future trend for excess power from history information about power generated by the power generation device and total power consumption of electronic equipment including the refrigerator; a storage chamber for storing a stored article; a temperature sensor for detecting the temperature of air in the storage chamber; a refrigerant circuit which cools the air in the storage chamber; and a control device which operates a refrigeration cycle of a refrigerant circulating through the refrigerant circuit, wherein the control device includes a refrigeration cycle control means for controlling the refrigeration cycle such that a detected value from the temperature sensor is maintained at a set temperature, an estimation means for estimating an excess power time band, during which excess power can be obtained, when information about the future predicted trend for excess power is received from the server, and a setting changing means for changing the set temperature to a lower temperature than a predetermined reference temperature in the excess power time band.
