The present invention discloses a control system and a control method of a refrigerator. The control system comprises a collection unit and a fan control unit, and the fan control unit controls a heat dissipation fan to operate at different rotation speeds according to a power-on signal of the refrigerator, a closing signal and an opening signal of the first air port collected by the collection unit. The present invention solves the problem that the hot air discharged out of the compressor compartment blends with cold air and re-enters the compressor compartment, and the problem of poor heat dissipation of the refrigerator when the refrigerator is embedded in the cupboard.

Proposed is a home appliance in which each of air inlets and each of air outlets formed on a machine room cover are configured to have flow rates different from each other. Accordingly, a design for the volume of air introduced into a machine room and the volume of air discharged to the outside of the machine room from the inside thereof may be facilitated.

A refrigerator is provided herein that includes a cabinet defining a refrigerated compartment and a machine compartment. A compressor is disposed within the machine compartment and adapted to compress a refrigerant within a refrigerant line. A heat exchanger is positioned in communication with the compressor and is adapted to reject heat from a refrigerant into the machine compartment. A fan is disposed between the heat exchanger and compressor. The fan is adapted to draw air from an area adjacent the machine compartment and through the heat exchanger. A funnel is disposed between the heat exchanger and the fan and directs air toward the fan. A tunnel is disposed between the fan and the compressor and directs forced air from the fan toward the compressor.

The present invention discloses a refrigerator, comprising a compressor compartment disposed in its lower rear portion thereof, wherein the back plate of the compressor compartment has a first air port and a second air port, and the bottom plate is provided with a third air port. The refrigerator further comprises a baffle movably disposed at the first air port to open or close the first air port. The baffle may prevent the hot air discharged from the compressor compartment from blending with cold air and re-entering the compressor compartment after the refrigerator is embedded in the cupboard.

A refrigerator includes a lowermost storage liner, an evaporator, an air supply duct, and at least one air supply fan. A storage compartment and a cooling chamber positioned under the storage compartment are defined in the storage liner. The evaporator is disposed in the cooling chamber and is configured to cool air passing through the evaporator so as to form cooling air supplied to the storage compartment. The air supply duct is disposed in a space defined by the storage liner and is configured to convey the cooling air cooled by the evaporator to the storage compartment. The air supply fan is disposed in the air supply duct and is configured to promote air circulation between the cooling chamber and the storage compartment.

A refrigerator having a flow channel device provided at opposite sides of a machinery compartment to introduce and discharge external air into the machinery compartment. The refrigerator includes a main body including an inner liner having a storage compartment defined therein, an outer liner coupled to an outside of the inner liner to form an external appearance thereof, and an insulation member filled between the inner liner and the outer liner, a machinery compartment, provided at a lower part of the main body, in which a compressor is disposed, and a flow channel device provided at opposite sides of the machinery compartment such that external air is introduced into the machinery compartment, flows along the machinery compartment, and is discharged from the machinery compartment, wherein the flow channel device extends through the insulation member filled between the outer liner and an inner wall of the machinery compartment.
