Embodiment 1

[0035] Such as figure 1 As shown, a piping system for an air conditioner outdoor unit in this embodiment includes a low-pressure valve pipe 6, one end of which is connected to a working port of the four-way valve 2, and the other end is connected to the low-pressure valve of the air conditioner ; The low-pressure valve tube 6 is provided with a muffler 3 . Outer diameter of the low-pressure valve tube 6 The outer diameter of the low-pressure valve tube 6 is 8-10 mm, and the inner diameter is 7-9 mm. The outer diameter is preferably 9.52 mm, and the inner diameter is preferably 8.02 mm. In the piping system of this embodiment, the muffler is arranged on the low-pressure valve pipe, and the entire piping system only contains one muffler, while the noise reduction performance is better than that of the existing noise reduction structure; and the muffler is arranged at a position far away from the compressor. The exhaust pipe is counterweighted, and the entire piping system is lo...

Embodiment 2

[0049] 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 conditioner outdoor unit pipe system and an air conditioner outdoor unit. The pipe system comprises a low-pressure valve pipe, one end of the low-pressure valve pipe is connected to one working port of a four-way valve, and the other end of the low-pressure valve pipe is connected with a low-pressure valve of an air conditioner. The low-pressure valve pipe is provided with a silencer. According to the air conditioner outdoor unit pipe system, the silencer is arranged on the low-pressure valve pipe, the whole pipe system is only provided with one silencer, and the noise elimination performance is superior to that of an existing noise elimination structure; and meanwhile, the silencer is arranged at the position away from a compressor, the silencer can also serve as an exhaust pipe balance weight, and the whole pipe 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...
