Title:
空調機器に使用する配管の接続方法
Document Type and Number:
Japanese Patent JP7360430
Kind Code:
B2
Abstract:
To solve such a problem that metal steel pipes and aluminum three-layer pipes having an intermediate layer made of aluminum are mainly used for connecting a heat source machine to an air-conditioning device, so that air contamination into an inner pipe (iron pipe or copper pipe) of the device corrodes the device internally, therefore not only useful life of the device is shortened, but also more time and effort are needed for construction work and transportation due to heavyweight of the metal material.SOLUTION: A method for connecting piping used for an air conditioning device includes steps of: using an oxygen permeation prevention resin pipe for a connection pipe 4 for connecting a forward main pipe 2 or return main pipe 3 for a heat medium communicating with a heat source machine to an air conditioning device 1; and using a rotary joint 5 configured so that a resin pipe fitted to an in-core is rotatable relative to a barrel body in a junction of a piping end when connecting pipes.SELECTED DRAWING: Figure 1
