Embodiment 1

[0035] Such as figure 1 As shown, an air conditioner outdoor unit piping system of this embodiment includes an exhaust pipe 1, one end of the exhaust pipe 1 is connected to a working port of a four-way valve 2, and the other end is connected to a compressor; The lower part of the exhaust pipe 1 is a U-shaped pipe section 11, and the U-shaped pipe section 11 at the lower part of the exhaust pipe 1 is provided with a muffler 3 on the pipe section close to the compressor side. In the piping system of this embodiment, the muffler is arranged on a section of the exhaust pipe close to the compressor. The entire piping system contains only one muffler. The sound absorbing performance is better than the existing silencing structure, and it can also be used as an exhaust pipe. Heavy, the entire piping system has low cost and high efficiency.

[0036] Such as figure 1 with Figure 5 As shown, the U-shaped pipe section 11 of the present embodiment extends upward and the pipe section on the ...

Embodiment 2

[0050] An outdoor unit of an air conditioner includes the piping system described in Embodiment 1. The air conditioner outdoor unit of this embodiment has a muffler arranged on a section of the exhaust pipe away from the compressor, and the entire piping system contains only one muffler. The noise elimination performance is better than the existing noise elimination structure, and it can also serve as an exhaust pipe. With counterweight, the entire piping system has low cost and high efficiency.

Abstract

The invention relates to an air-conditioning outdoor unit and a piping system of the air-conditioning outdoor unit. The piping system comprises an exhaust pipe, wherein one end of the exhaust pipe is connected with a working port of a four-way valve; the other end of the exhaust pipe is connected with a compressor; a U-shaped pipe section is arranged at the lower part of the exhaust pipe; and a silencer is arranged on one side, close to the compressor, of the U-shaped pipe section. According to the piping system of the air-conditioning outdoor unit, the silencer is arranged on a section, far away from the compressor, of the exhaust pipe; the whole piping system only comprises the single silencer; the silencing performance of the silencer is better than that of the existing silencing structure; the silencer can also serve as a counter weight of the exhaust pipe at the same time; and the whole piping system is low in cost and high in efficiency.

Description

Technical field [0001] The present invention relates to the technical field of air conditioners, in particular to an air conditioner outdoor unit piping system and an air conditioner outdoor unit. Background technique [0002] The discharge pressure of the compressor cylinder has a periodic change pattern, which causes the refrigerant pressure in the piping system to also have a pulsating nature. When this pressure pulsation is large enough, it will excite the pipes that transport the refrigerant to vibrate. The thin-walled structural parts of the indoor unit are excited by the vibration of the evaporator assembly pipeline, and will radiate noise that is multiplied by the compressor rotation frequency. This kind of noise has obvious tonality and is not easy to be masked by the wind noise of the indoor unit. Once it is generated, it will be complained by users. By adding a muffler to the piping system, the pressure pulsation of the refrigerant can be attenuated. Summary of the ...
