Abstract
A refrigerator includes a first refrigeration cycle unit that is configured to circulate a first refrigerant and that includes a first compressor, a first condenser, a first expansion device, and a first evaporator, a second refrigeration cycle unit that is configured to circulate a second refrigerant and that includes a second compressor, a second condenser, a second expansion device, and a second evaporator, a first valve unit installed at an outlet side of the first compressor, and a first hot gas path configured to extend from the first valve unit to the second evaporator and configured to supply the first refrigerant to the second evaporator.
Claims20
A refrigerator comprising:
- a first refrigeration cycle that is configured to circulate a first refrigerant, and that includes a first compressor, a first condenser, and a first evaporator;
- a second refrigeration cycle that is configured to circulate a second refrigerant, and that includes a second compressor, a second condenser, a second evaporator, and a third evaporator that includes a first pipe in which the second refrigerant is introduced into after having passed through at least one of the second compressor or the second condenser and a second pipe;
- a first valve that is installed at an outlet side of at least one of the first compressor or the first condenser;
- a hot gas path that is configured to extend from the first valve to the third evaporator, and that is configured to supply the first refrigerant to the third evaporator;
- wherein the hot gas path is configured to extend from the third evaporator to the second evaporator.

A refrigerator comprising:
- a first refrigeration cycle that is configured to circulate a first refrigerant and that includes a first compressor, a first condenser, and a first evaporator;
- a second refrigeration cycle that is configured to circulate a second refrigerant and that includes a second compressor, a second condenser, and a second evaporator;
- a first valve that is installed at an outlet side of at least one of the first compressor or the first condenser;
- and
- a first hot gas path that is configured to extend to the second evaporator from the first valve,
- wherein the second evaporator comprises a first pipe that is configured to guide flow of the first refrigerant and a second pipe that is configured to guide flow of the second refrigerant and that is configured to connect to the first hot gas path,
- wherein the refrigerator further comprises:
- a third evaporator which is located in the second refrigeration cycle and that is connected to the second evaporator;
- a second valve that is disposed at an outlet side of at least one of the second compressor or the second condenser;
- a second hot gas path that is configured to supply the second refrigerant after the refrigerant has passed through the at least one of the second second compressor or the second condenser to the third evaporator, wherein the second hot gas path is configured to connect the second valve and the third evaporator.
