Abstract
This refrigeration device, which cools by means of a refrigeration cycle using a refrigerant, is provided with: a door; a box which has a peripheral edge that is opposite of the outer peripheral portion of the door when the door is in a closed state, and which is internally cooled by the refrigerant; and multiple pipes which are arranged along the surface of the peripheral edge and which circulate a refrigerant warmed by the compression action of a compressor.
Claims8
A refrigeration apparatus configured to perform cooling through a refrigeration cycle using a refrigerant, the refrigeration apparatus comprising:
- a door;
- a box section comprising a circumferential edge section that faces an outer circumferential portion of the door with the door closed, wherein an interior of the box section is cooled by the refrigerant;
- packing configured to be held between the outer circumferential portion of the door and the circumferential edge section with the door closed;
- and
- a plurality of pipes disposed so as to be aligned along a surface of the circumferential edge section, the plurality of pipes circulating the refrigerant that is warmed by a compressing action of a compressor, wherein:
- the plurality of pipes individually belong to a plurality of refrigeration circuits in which refrigerants circulate independently of each other,
- the plurality of pipes comprise a first annular pipe and a second annular pipe that is disposed in such a manner as to be superposed on an outer circumferential side of the first annular pipe so as to surround the first annular pipe, and
- the box section comprises an inner box section and an outer box section that covers the inner box section, and the box section further comprises a metallic plate member that is fixed to an inner surface of the circumferential edge section and an inner surface of the outer box section, the inner surface of the outer box section being located on a side facing the circumferential edge section.
