PROTECTIVE DUCT DEVICE FOR REFRIGERANT PIPE FOR AIR CONDITIONER, AND EXPANSION PREVENTING TOOL FOR PROTECTIVE DUCT OF REFRIGERANT PIPE FOR AIR CONDITIONER

摘要

PROBLEM TO BE SOLVED: To improve workability of piping of a refrigerant pipe by providing a protective duct for easily storing the refrigerant pipe for an air conditioner piped along a wall surface to protect it.

SOLUTION: A longitudinally continuing chopped section is formed in the protective duct formed of a hollow cylinder having a bendable bellows section. The peripheral wall is expanded to store the refrigerant pipe for the air conditioner from the chopped section, thereby protecting the refrigerant pipe extremely easily.
