Title:
REFRIGERATOR
Document Type and Number:
Japanese Patent JP2013057415
Kind Code:
A
Abstract:

To reduce power consumption by eliminating the shortage of a refrigerant caused by a residual refrigerant in a pipe generating in switching refrigerant pipes, and to reduce refrigerant flowing noise generated when the refrigerant passes through a switch valve.

In this refrigerator having a refrigerant circuit successively connecting a compressor, a heat radiating means, a pressure reducing means and a cooler, the heat radiating means includes a first heat radiating means radiating heat to the outside of the refrigerator, and a second heat radiating means for heating a partitioning section, and further includes a first refrigerant flow channel for allowing the refrigerant compressed by the compressor to flow to the first heat radiating means and the second heat radiating means, a second refrigerant flow channel for making the refrigerant bypass the first refrigerant flow channel after circulating to the first heat radiating means, and a flow channel switching means for switching the first refrigerant flow channel and the second refrigerant flow channel. Internal volumes of the first refrigerant flow channel and the second refrigerant flow channel are smaller than an internal volume of the first heat radiating means.
