CONSTRUCTION METHOD OF CONNECTION HEAT INSULATION MEMBER, CONNECTION HEAT INSULATION MEMBER, CONNECTION HEAT INSULATION MEMBER UNIT AND REFRIGERANT PIPING UNIT

摘要

To be able to be suitably constructed even in a narrow space in the refrigerant piping.SOLUTION: A construction method of connection heat insulation member for heat insulating the connection in which one refrigerant piping covered with a piping heat insulation member and the other refrigerant piping covered with the piping heat insulation member are connected together, the method comprises: a first step of inserting the piping heat insulation member into the cylindrical connection heat insulation member having an inner diameter capable of covering the external diameter of the piping heat insulation member; a second step in which the one refrigerant piping unit and the other refrigerant piping unit are connected together with a mechanical joint component; a third step of moving the connection heat insulation member to a position corresponding to the mechanical joint component by sliding it; and a forth step of fixing the connection heat insulation member at a fixed home position.SELECTED DRAWING: Figure 3
