<P>PROBLEM TO BE SOLVED: To provide a refrigeration device capable of inhibiting the dew formation on a connection pipe with a simple structure by minimizing the use of a heat insulating material for preventing the dew formation. <P>SOLUTION: In a refrigerant circuit where a use unit and a heat source unit are connected by the connection pipe 30, a double piping part 50 composed of a first pipe 41 and a second pipe 42 penetrated through a center of the first pipe 41 is mounted on the connection pipe 30, a low-pressure gas refrigerant is circulated in an internal space of the second pipe 42, and the high-pressure liquid refrigerant is circulated between the first pipe 41 and the second pipe 42. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
