Refrigerator{REFRIGERATOR}

The present invention relates to a refrigerator, and more specifically, to a refrigerator including a resonator that can reduce noise generated in a machine room.

A refrigerator is a home appliance that supplies cold air generated through heat exchange with a refrigerant circulating in a cooling cycle to a storage room to keep various types of storage items fresh for a long period of time.

Specifically, the cold air supplied to the storage compartment may be generated by taking heat from the refrigerator as the refrigerant circulating in the order of the compressor, condenser, expansion valve, evaporator, and compressor flows into the evaporator, and the liquid refrigerant is vaporized into gaseous refrigerant. .

The compressor increases the temperature and pressure of the low-temperature and low-pressure gas refrigerant introduced from the evaporator into the high-temperature and high-pressure gas refrigerant and sends it to the condenser.

The condenser condenses the refrigerant flowing in from the compressor by external air, and the refrigerant flowing in from the condenser passes through an expansion valve with a relatively narrow diameter and expands under reduced pressure.
