Embodiment 1

[0035] Such as figure 1 As shown, a piping system for an air conditioner outdoor unit in this embodiment includes an exhaust pipe 1, one end of which is connected to a working port of the four-way valve 2, and the other end is connected to the 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 near 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 only contains one muffler, and the noise reduction performance is better than that of the existing noise reduction structure. Heavy, low cost and high efficiency of the whole piping system.

[0036] Such as figure 1 with Figure 5 As shown, the U-shaped pipe section 11 in this embodiment is extended upwards and bent to form a horizontal straight pipe section 12 near...

Embodiment 2

[0050] An outdoor unit of an air conditioner, comprising the piping system described in Embodiment 1. The outdoor unit of the air conditioner in this embodiment arranges the muffler on a section of the exhaust pipe far away from the compressor, and the entire piping system only includes one muffler, and the noise reduction performance is better than that of the existing noise reduction structure, and it can also serve as an exhaust pipe Counterweight, the entire piping system is low cost and efficient.

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 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 law, 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 pipeline that transmits the refrigerant to vibrate. The thin-walled structural parts of the indoor unit are excited by the vibration of the pipeline of the evaporator assembly, and will radiate noise that is multiplied by the rotation frequency of the compressor. This kind of noise has obvious tonality, and it is not easy to be masked by the wind noise of the indoor unit. Once it occurs, it will be complained by users. By adding a muffler to the piping system, the pressure pulsation of the refrigerant can be attenuated. Conten...
