Abstract
Provided is a piping system for an air conditioner installed in a vehicle that can achieve appropriate weight reduction while ensuring appropriate pressure resistance as the piping system as a whole. A circulation path that connects component devices of an air conditioner (8) in an annular shape to circulate a refrigerant (C) is formed by each pipe body extending between the component devices. At least one of the pipe bodies includes: a resin hose (2) embedded with a non-metal reinforcing material (3f) or a resin pipe (5) embedded with a non-metal reinforcing material (6f), and the resin pipe bodies (2), (5) are employed in 50% or more of a total length of each of the pipe bodies constituting the circulation path.
