Abstract:
1. A method of controlling a refrigerator, in which a difference between a temperature of an inside of a freezer compartment and a predetermined temperature is referred to as a first error temperature and a difference between a temperature of an inside of a refrigerator compartment and the predetermined temperature is referred to as a second error temperature, the method comprising: varying a stroke of an inverter linear compressor to operate the inverter linear compressor by a maximum output when the first or second error temperature is higher than a maximum output temperature; and varying the stroke of the inverter linear compressor at least once in a single freezer or refrigerator cycle to operate the inverter linear compressor when the first or second error temperature is not more than the maximum output temperature, wherein, in the varying the stroke of the inverter linear compressor at least once in the single freezer or refrigerator cycle, when the first error temperature is not more than the maximum output temperature and when the second error temperature is not more than the maximum output temperature, a first period of one cycle of the freezer compartment follows a second period of one cycle of the refrigerator compartment, wherein the first period is longer than the second period, and wherein a first output power of the inverter linear compressor during the first period is greater than a second output power of the inverter linear compressor during the second period.
