Definitions

  • An outdoor fan (26) is installed in the outdoor unit (20).
  • the outdoor fan (26) conveys the air passing through the outdoor heat exchanger (24).
  • the outdoor heat exchanger (24) is a heat source heat exchanger. In the outdoor heat exchanger (24), the refrigerant flowing inside and the outdoor air exchange heat with each other.
  • a first joint member (60A) is provided at the end of the gas shutoff valve (50A).
  • a second joint member (60B) is provided at the end of the liquid stop valve (50B).
  • the gas connecting pipe (12A) is connected to the first joint member (60A).
  • the liquid communication pipe (12B) is connected to the second joint member (60B).
  • the first joint member (60A) and the second joint member (60B) form an outdoor joint member that is a heat source side joint member.
  • the joint member (60) includes a spacer (90) and a lid member (91) before the air conditioner (10) is installed.
  • the straight portion (14) of the communication pipe (12) is removed from the nut (70) and the spacer (90). Insert it inside the stop member (80).
  • the retaining member (80) is loosely fitted in the inner space (S) in the axial direction.
  • the nut (70) and the retaining member (80) With the retaining member (80) that is deformed in the radial direction of the nut (70), the nut (70) and the retaining member (80) have the connecting pipe (12) connected to the joint member (60). Not attached, it is attached to the joint body (61).
  • the lid member (91) may be configured to cover the joint side opening (65) when the joint member (60) is not connected. This makes it possible to reliably prevent dust from entering the unit-side refrigerant flow paths (21, 41) through the joint-side opening (65) when the outdoor unit (20) and the indoor unit (40) are transported.
  • the spacer portion (99) is located between the step surface (61c) of the joint body (61) and the nut (70) as in the embodiment. As a result, the spacer portion (99) prevents the nut (70) from being tightened on the joint body (61) side.
  • the nut (70) and the retaining member (80) are attached in advance to all the joint members (60A, 60B, 60C, 60D) of the outdoor unit (20) and the indoor unit (40).
  • the nut (70) and the retaining member (80) may be attached to only part of these joint members (60) in advance.
  • the cross-sectional shape of the tightening suppressing member (90) perpendicular to the axis may be U-shaped.
  • the present disclosure is useful for a fluid unit, a refrigeration unit, a heat source unit, a utilization unit, and a refrigeration unit.

Abstract

La présente invention concerne un élément joint (60) comprenant : un corps de joint (61) qui est disposé au niveau d'une partie extrémité d'un canal de fluide (21, 41) et dans lequel un filetage mâle (62) est formé ; un écrou (70) dans lequel est formé un filetage femelle (73) correspondant au filetage mâle (62), et à travers lequel une section droite (14) d'une tuyauterie de communication (12) est insérée ; et un élément de retenue (80) qui est disposé entre le corps de joint (61) et l'écrou (70) et qui se déforme vers l'intérieur dans la direction radiale de l'écrou (70) suite à la fixation de l'écrou (70) au corps de joint (61). L'écrou (70) et l'élément de retenue (80) sont fixés au corps de joint (61) dans un état non raccordé dans lequel la tuyauterie de communication (12) n'a pas été raccordée à l'élément joint (60).
