Abstract: Provided are a refrigerator and a cloud server that diagnose a cause of an abnormal state. According to an embodiment of the present disclosure, an abnormal state diagnosis unit included in the refrigerator or the cloud server generates information on the abnormal state of the refrigerator based on similarity between stored first group of information and a normal pattern, and a cause diagnosis unit generates, when the abnormal state diagnosis determines that a state of the refrigerator is an abnormal stte, information on cause of the abnormal state based on similarity between stored second group of information and a defect pattern.

Abstract: The present invention relates to a temperature-context-aware refrigerator and a method for controlling the same. A temperature-context-aware refrigerator according to an embodiment of the present invention comprises: a temperature context awareness unit for sensing a temperature of at least one storage compartment, and when the difference between the sensed temperature and a temperature set for the corresponding storage compartment is equal to or greater than a predetermined level, generating load-responsive operation information including a target temperature lower or higher than the set temperature; a temperature control unit for controlling a temperature sensor and the temperature context awareness unit, and performing a load-responsive operation for controlling the temperature of the storage compartment by using the load-responsive operation information; and a database unit which is required for the temperature context awareness unit to generate the load-responsive operation information.
