Abstract
An air conditioning piping system of the disclosure includes a refrigerant pipe made of a plastic material and configured to provide a fluid flow between components constituting an air conditioning system; at least one connection flange made of the plastic material and configured to provide a connection between the refrigerant pipe and components constituting the air conditioner system; and at least one charging port made of the plastic material and having a charging valve configured to inject a refrigerant into the refrigerant pipe.
Claims13
An air conditioning piping system, comprising:
- a refrigerant pipe made of a plastic material and configured to provide a fluid flow between components constituting an air conditioning system;
- a connection flange made of the plastic material and configured to provide a connection between the refrigerant pipe and components constituting the air conditioner system;
- and
- a charging port made of the plastic material and comprising a charging valve configured to inject a refrigerant into the refrigerant pipe,
- wherein the connection flange is bonded to the refrigerant pipe by laser welding in a state in which one side end portion of the refrigerant pipe is coupled, and the charging port is bonded to the refrigerant pipe by laser welding in a state seated at an upper side of an outer circumferential surface of the refrigerant pipe,
- the charging port comprises:
- a main body in which the charging valve configured to inject the refrigerant into a refrigerant injection hole formed in the refrigerant pipe is disposed;
- and
- a fixing part extended to a lower end side of the main body to couple the main body to the outer circumferential surface of the refrigerant pipe, wherein the fixing part is formed to be coupled to the refrigerant pipe except for a portion of a lower side of the outer circumferential surface of the refrigerant pipe, and when the fixing part is coupled to the outer circumferential surface of the refrigerant pipe, a thickness thereof is formed to decrease from an upper end side of the main body to the lower end side of the main body so as to flexibly generate an elastic restoring force.

- the method comprising:
- producing each of a refrigerant pipe, a connection flange, and a charging port using a plastic material;
- coupling the connection flange to at least one end side of the refrigerant pipe and then bonding the refrigerant pipe and the connection flange to each other by laser welding using a laser device;
- forming a refrigerant injection hole on an outer circumferential surface of the refrigerant pipe using a drilling device;
- and
- coupling a fixing part of the charging port at a position in which the refrigerant injection hole of the refrigerant pipe is formed, and then bonding the refrigerant pipe and the connection flange to each other by the laser welding using the laser device.
