REFRIGERATION CYCLE DEVICE

The purpose of the present disclosure is to provide a refrigeration cycle device which is advantageous in improving durability in an environment in which vulcanization gas is present. This refrigeration cycle device is provided with: a first refrigerant tube; a second refrigerant tube; a solder that joins the end of the first refrigerant tube to the end of the second refrigerant tube; a first coating film that covers the exposed part of the solder and is made of a corrosion inhibitor; the first coating layer may also be made of a coating to which a corrosion inhibitor is added. The corrosion inhibitor of the first coating layer may be the same substance as the corrosion inhibitor of the first coating film. 本公开的目的在于提供一种制冷循环装置，其在提高存在硫化气体的环境下的耐久性方面有利的。本公开的制冷循环装置具备第一制冷剂管、第二制冷剂管、将第一制冷剂管的端部接合于第二制冷剂管的端部的钎料、覆盖钎料的露出部并由腐蚀抑制剂制成的第一覆膜、以及覆盖第一覆膜的外表面的第一涂装层。第一涂装层也可以由添加了腐蚀抑制剂的涂料制作。第一涂装层的腐蚀抑制剂可以是与第一覆膜的腐蚀抑制剂相同的物质。
