| 摘要 |
The invention provides a refrigerant heating apparatus assembly that can improve the work efficiency and reliability of a heating piping and the strength of a refrigerant heating apparatus, and attaching structure thereof. In a refrigerant heating apparatus assembly (30), a copper inner pipe (31), which constitutes part of a refrigerant piping of a refrigerant circuit (11), is inserted into an outer pipe (32), which is a magnetic body; the inner pipe (31) is expanded in directions in which its outer diameter enlarges and thereby is mated to the interior of the outer pipe (32); and, furthermore, an induction heating coil (33) is mounted to the outer circumference of the outer pipe (32). |
