Branch pipe coupling and air conditioner provided with the same

Abstract

The present invention comprises a branching pipe joint, for distributing a refrigerant that flows within a main pipe to two flows, and an air conditioner provided therewith, and achieves both the compaction of the vicinity of the branch part and the prevention of drift therein. A branching pipe joint (181) comprises a substantially Y-pipe shaped branch part (182), a first branch nozzle part (183), a second branch nozzle part (184), and a first branch pipe (186). The first branch pipe (186) is a pipe member, wherein one end part is connected to a tip part of the first branch nozzle part (183) during plumbing work. The first branch nozzle part (183) and the second branch nozzle part (184) are disposed so that a spacing between a portion of the tip part of the first branch nozzle part (183) nearest the second branch nozzle part (184) side and a portion of the second branch nozzle part nearest the tip part of the first branch nozzle part is less than or equal to 40 mm.

Description

technical field [0001] The present invention relates to a pipe joint for branching and an air conditioner having the pipe joint for branching. Background technique [0002] In conventional air conditioners, an outdoor unit and an indoor unit are connected by connection pipes such as gas refrigerant connection pipes and liquid refrigerant connection pipes, thereby constituting a so-called stand-alone air conditioner. As shown in FIG. 1, this type of air conditioner 1 is provided with a plurality of indoor units 3 (four in FIG. 1), and the connecting pipe 4 is branched so that the refrigerant can be distributed from the connecting pipe 4 to each indoor unit 3. , or a plurality of outdoor units 2 (3 units in FIG. 1 ), and connecting piping 4 (gas refrigerant connecting piping 5 and liquid refrigerant connecting piping 6 in FIG. 1 ) are branched so that the refrigerant can be diverted from the connecting piping. 4 Status assigned to each outdoor unit 2. [0003] Next, the bran...

Problems solved by technology

However, when the T-shaped branch pipe 91 is arranged in the same horizontal branch arrangement as that of the Y-shaped branch pipe 81, that is, the T-shaped branch portion 92 of the T-shaped branch pipe 91 faces the horizontal direction, and the first branch nozzle portion 93 and The second branch nozzle part 94 is arranged at the same height, and at this time, the refrigerant flowing into the T-shaped branch pipe 91 from the confluence connection pipe or the branch connection pipe can also be aligned in a substantially symmetrical direction with respect to the center line OO of the inlet pipe part 82a. However, in the T-shaped branch part 92, since it is not branched in a substantially symmetrical direction with the center line O-O of the inlet pipe part 92a, it is easy to generate a bias flow.

[0011] It can be seen that no matter which of the above-mentioned existing Y-shaped branch pipes 81 and T-shaped branch pipes 91 is used as the pipe joint for branching, it is impossible to shorten the size near the branch part and prevent the flow deviation at the branch part at the same time.
