Abstract: A refrigeration cycle of a refrigerator includes a first refrigeration cycle in which a first refrigerant flows along a first refrigerant tube and a second refrigeration cycle in which a second refrigerant flows along a second refrigerant tube. First and second compressors compress each of the first and second refrigerants, and a combined condenser condenses each of the first and second refrigerants. First and second expansion valves phase-change each of the first and second refrigerants passing through the combined condenser, and first and second evaporators change the refrigerant passing through each of the first and second expansion valves into a low-temperature low-pressure gaseous refrigerant.

Abstract: A refrigerator according to an embodiment includes: a duct dividing the inside of a storage compartment body into a storage compartment and an air channel and having a main discharge port and a sub-discharge port; an air guide dividing the air channel into a first channel communicating with the main discharge port and a second channel guiding air in the first channel to the sub-discharge port; a heat exchanger provided in the first channel; and a fan suctioning air in the storage compartment and sending the air to the first channel. According to the refrigerator, it is possible to maximize the volume of the storage compartment and separately discharge air to the main discharge port and the sub-discharge port, using a simple structure.
