The present invention provides a refrigerator, and aims at eliminating refrigerant shortage caused by residual refrigerant in a tubing occurring at the moment of changing a refrigerant tubing, so as to reduce consumed electric power, and aims at reducing refrigerant flowing sound generated when the refrigerant flows through a changeover valve. The refrigerator has a refrigerant loop in which a compressor, a heat dissipation mechanism, a decompressing mechanism, and a cooler are connected in order, wherein the heat dissipation mechanism comprises a first heat dissipation mechanism used for performing heat dissipation towards an outer part of the refrigerator, a second heat dissipation mechanism used for heating a separating part of a storage room. The refrigerator comprises: a first refrigerant flow path used for enabling the refrigerant compressed by the compressor to flow through the first heat dissipation mechanism and the second heat dissipation mechanism ; a second refrigerant flow path used for bypassing the first refrigerant flow path after the refrigerant circulates in the first heat dissipation mechanism; and a flow path switching mechanism used for switching the first refrigerant flow path and the second refrigerant flow path, wherein inside capacity of the first refrigerant flow path and the second refrigerant flow path is less than inside capacity of the first heat dissipation mechanism.
Description
technical field [0001] The present invention relates to refrigerators. Background technique [0002] As a conventional refrigerator, there is known a refrigerator in which a dew condensation prevention pipe is disposed on an opening edge portion of a storage compartment. A plurality of storage rooms are provided in the heat insulation box constituting the main body of the refrigerator, and heat insulating doors for opening and closing front openings of the storage rooms are attached. The contact portion between the opening and the door, that is, the edge of the opening of the storage compartment is cooled by the cool air inside the box, and dew condensation is likely to occur on the surface due to the temperature difference with the outside air. In order to suppress this dew condensation phenomenon, the dew condensation prevention piping utilizing the radiating pipe of the refrigeration cycle is embedded in the opening edge of the storage compartment. [0003] In the refri...
