Problems solved by technology
[0008] In this case, the cooled storage room can maintain the temperature within the appropriate range, but there is a problem that the temperature of the uncooled storage room rises beyond the normal range
Moreover, in the state where one storage chamber needs to be cooled, if it is detected that the temperature of the other storage chamber exceeds the normal range, there is a problem that the cooling of the other storage chamber cannot be realized immediately.
[0009] Finally, in the structure that requires independent cooling of the storage room, cold air cannot be supplied to the appropriate location at the appropriate time, resulting in a problem that the operating efficiency of the refrigerator is reduced

The present invention relates to a refrigerator and a control method thereof. The control method of the refrigerator in this embodiment includes: starting the compressor to drive the refrigeration cycle system including the first evaporator and the second evaporator; The step of supplying refrigerant to the evaporator to supply cold air to the refrigerator compartment and the freezer compartment at the same time; increasing the flow rate of the refrigerant supplied to the first evaporator for a first set time to limit the cooling flow to the second evaporator the step of increasing the refrigerant flow rate to the second evaporator for a second set time to limit the refrigerant flow rate to the first evaporator.
Description
technical field [0001] The present invention relates to a refrigerator and a control method thereof. Background technique [0002] Usually, the refrigerator is provided with a plurality of storage chambers for storing items, so as to freeze or refrigerate food, and one side of the storage chambers is opened to accommodate and take out the above-mentioned food. The plurality of storage chambers include a freezer chamber for frozen storage of food and a refrigerator chamber for cold storage of food. [0003] In a refrigerator, a refrigeration system that is circulated by a refrigerant is driven. The devices constituting the above-mentioned refrigeration system include a compressor, a condenser, an expansion device, and an evaporator. The evaporator may include a first evaporator disposed on one side of the refrigerating chamber and a second evaporator disposed on one side of the freezing chamber. [0004] The cool air stored in the refrigerator compartment is cooled by the ...
