Problems solved by technology
[0011] In this case, there is a problem that the temperature of the storage room that is cooled can maintain the proper range, but the temperature of the storage room that is not cooled rises beyond the normal range
[0012] Also, in the case where it is sensed that the temperature of the other storage chamber exceeds the normal range in a state where cooling of one storage chamber is required, there arises a problem that the cooling of the above-mentioned other storage chamber cannot be performed immediately.
[0013] As a result, in the structure that independently cools the storage room, cold air cannot be supplied to the right place at the right time, and the operating efficiency of the refrigerator decreases.
[0014] On the other hand, conventionally, when the outlet sides of the refrigerant supply unit 170 are opened in both directions in order to cool a plurality of storage chambers together, the refrigerant is biased toward one of the plurality of evaporators.
[0015] In particular, when a three-way valve is used as the refrigerant supply unit, the physical balance of the three-way valve cannot be maintained, so there is a problem that a large amount of refrigerant flows into one evaporator and relatively little refrigerant flows into other evaporators

Provided are a refrigerator (10d) and a control method thereof. The refrigerator (10d) includes a compressor (110) compressing a refrigerant, a condenser (120) condensing the refrigerant compressed in the compressor(110), a refrigerant tube (100) guiding a flow of the refrigerant condensed in the condenser (120), a plurality of expansion devices (141, 145, 143) decompressing the refrigerant condensed in the condenser (120), a plurality of evaporators (150, 160) including first (150) and second (160) evaporators to evaporate the refrigerant decompressed in the plurality of expansion devices (141, 145, 143), a first evaporation passage (101, 105) in which a portion (141, 145) of the plurality of expansion devices (141, 145, 143) is disposed, the first evaporation passage guiding introduction of the refrigerant into the first evaporator (150) of the plurality of evaporators (150, 160), a second evaporation passage (103) in which the other portion (143) of the plurality of expansion devices (141, 145, 143) is disposed, the second evaporation passage (103) guiding introduction of the refrigerant into the second evaporator (160) of the plurality of evaporators (150, 160), and a flow adjusting unit (130) disposed in the refrigerant tube (100) to branch the refrigerant into the first evaporation passage (101, 105) and the second evaporation passage (103).
Description
Technical field [0001] The invention relates to a refrigerator and a control method thereof. Background technique [0002] Generally, a refrigerator has a plurality of storage chambers for accommodating stored items for freezing or refrigerating and storing food, and one side of the storage chamber is formed in an open manner to be able to store and take out the food. The above-mentioned multiple storage compartments include: a freezer compartment, used for frozen storage of food, and a freezer compartment, used for refrigerated storage of food. [0003] In the refrigerator, a refrigeration system circulated by a refrigerant is driven. The devices constituting the above refrigeration system include a compressor, a condenser, an expansion device, and an evaporator. The above-mentioned evaporator may include a first evaporator disposed on one side of the refrigerating compartment and a second evaporator disposed on one side of the freezing compartment. [0004] The cold air stored i...
