Refrigerator

A refrigerator comprising:

• a compressor configured to compress refrigerant;
• a condensing unit configured to pass the compressed refrigerant;
• and
• a first heat exchanger unit and a second heat exchanger unit, each of the first heat exchanger unit and the second heat exchanger unit being configured to provide heat exchange as the refrigerant passes therethrough,
• wherein the refrigerator is configured such that, when a defrosting mode is performed for one of the first heat exchanger unit and the second heat exchanger unit, refrigerant having a relatively high temperature is supplied to the one of the first heat exchanger unit and the second heat exchanger unit and refrigerant having a relatively low temperature is supplied to the other one of the first heat exchanger unit and the second heat exchanger unit.

A refrigerator comprising:

• a compressor configured to compress refrigerant;
• a condensing unit configured to pass the compressed refrigerant;
• and
• a first heat exchanger unit and a second heat exchanger unit, each of the first heat exchanger unit and the second heat exchanger unit being configured to provide heat exchange as the refrigerant passes therethrough,
• wherein the refrigerator is configured such that a flow direction of the refrigerant through each of the first heat exchanger unit and the second heat exchanger unit during a cold supply mode is the same direction as a flow direction of the refrigerant through each of the first heat exchanger unit and the second heat exchanger unit during a defrosting mode.
