Title:
REFRIGERATING DEVICE
Document Type and Number:
Japanese Patent JP2011112351
Kind Code:
A
Abstract:
To provide a refrigerating device effectively cooling the inside of the refrigerating device down to ultralow temperature.
In the refrigerating device R1, a refrigerant delivered from a compressor 14 is condensed, and then, is decompressed by a capillary tube 18, and is evaporated by an evaporator 13 so as to exhibit cooling action. The capillary tube 18 is inserted into suction piping 32 through which the refrigerant returning from the evaporator 13 to the compressor 14 passes, and a double tube structure is provided. The suction piping 32 (piping 32A) in which the capillary tube 18 is inserted in order to obtain the double tube structure, is surrounded by a heat insulating material 35.
