Abstract:
1. A method of controlling a refrigerator, comprising: varying a stroke of an inverter linear compressor to operate the inverter linear compressor at a maximum output when a temperature of an inside of a freezer compartment or a refrigerator compartment is higher than a maximum output temperature; and varying the stroke of the inverter linear compressor for one period interval to operate the inverter linear compressor when the temperature of the inside of the freezer compartment or the refrigerator compartment is no more than the maximum output temperature, wherein, in varying the stroke of the inverter linear compressor for the one period interval to operate the linear compressor when the temperature of the inside of the freezer compartment or the refrigerator compartment is no more than the maximum output temperature, the stroke of the inverter linear compressor is varied so that an output varies: when the temperature of the inside of the freezer compartment is between a first target temperature and a first set temperature; when the temperature of the inside of the freezer compartment is between the first target temperature and a second set temperature; when the temperature of the inside of the refrigerator compartment is between a second target temperature and a third set temperature; and when the temperature of the inside of the refrigerator is between the second target temperature and a fourth set temperature, wherein the first set temperature is higher than the second set temperature, and the third set temperature is higher than the fourth set temperature, wherein a first period of the stroke of the inverter linear compressor, which varies when the temperature of the inside of the freezer compartment is higher than the first set temperature, precedes a second period of the stroke of the inverter linear compressor, which varies when the temperature of the inside of the freezer compartment is higher than the second set temperature, and wherein the first period is longer than the second period.
