Claim Text:
1. A refrigerator, comprising: a refrigerating chamber; a freezing chamber; one or more refrigerating chamber temperature sensors configured to sense a temperature of the refrigerating chamber; one or more freezing chamber temperature sensors configured to sense a temperature of the freezing chamber; and a refrigerating cycle apparatus configured to generate cool air, the refrigerating cycle apparatus comprising; a controller configured to control the refrigerating cycle apparatus to generate cool air, and to control driving of the refrigerator based on an amount of change in the refrigerating chamber temperature or an amount of change in the freezing chamber temperature calculated per predetermined time period, wherein the controller calculates a change in the amount of temperature change by calculating a difference between a first amount of change in the refrigerating chamber temperature in a first time period and a second amount of change in the refrigerating chamber temperature in a second time period, or calculating a difference between a first amount of change in the freezing chamber temperature in a first time period and a second amount of change in the freezing chamber temperature in a second time period, and wherein, if the change in the amount of temperature change is greater than a first reference value, the controller increases the cooling capacity of the compressors, if the change in the amount of temperature change is smaller than the first reference value but larger than a second reference value, the controller maintains the current cooling capacity of the compressors and if the change in the amount of temperature change is smaller than the second reference value, the controller decreases the cooling capacity of the compressors.
