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 on the side away from the compressor. In the piping system of this embodiment, the muffler is arranged on a section of the exhaust pipe far away from the compressor. The entire piping system only contains one muffler. Heavy, low cost and high efficiency of the whole piping system.

[0036] The outer diameter of the exhaust pipe 1 in this embodiment is 3.5mm-6mm, which can be selected as 4mm, 4.5mm, 5mm, and 5.5mm; the wall thickness of the exhaust pipe 1 is 0.5mm-0.75mm, which can be Selected as 0.55mm, 0.6mm and 0.7mm. By reasonably li...

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 condenser outdoor unit tubing system and an air condenser outdoor unit. The tubing system comprises an exhaust tube, one end of the exhaust tube is connected to one working port of a four-way valve, and the other end of the exhaust tube is connected with a compressor; and a U-shaped tube section is arranged at the lower portion of the exhaust tube, and a silencer is arranged on the section on the side, far away from the compressor, of the U-shaped tube section. According to the air condenser outdoor unit tubing system, the silencer is arranged on the section, close to the compressor, of the exhaust tube, only one silencer is arranged on the whole tubing system, the silencing performance is better than that of an existing silencing structure, meanwhile, the silencer can serve as an exhaust tube additional weight, and the whole tubing 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...
