KR-20260062799-A - Refrigerant distribution manifold and manufacturing method of the same

Abstract

A refrigerant distribution manifold is introduced, comprising a main body including: a valve coupling portion coupled to face a valve on the side; a pipe coupling portion coupled to the front to allow refrigerant to flow in or out; a flow path communicating with the valve coupling portion or the pipe coupling portion; and a plug coupled to the end of the flow path formed by processing to block communication between the flow path and the outside.
