Problems solved by technology

Since the four-way valve is a suspended mass body, when the compressor is running, the four-way valve is like a rattle in the air, vibrating strongly, which may easily lead to fatigue and fracture of the pipeline
In addition, the compressor, four-way valve and connected pipes are exposed, which become the source of acoustic vibration, making the cooling parts of the air conditioner very noisy

Embodiment 1

[0037] Such as Figure 1 to Figure 4As shown, the vibration and noise reduction device includes a compressor main body 10, a four-way valve 20, a fastening mechanism and a vibration isolation and noise reduction cylinder 30. The four-way valve 20 has an exhaust port 21 and a return air port 22. Both the exhaust port 21 and the air return port 22 are connected to the compressor main body 10 through the pipeline 25, the compressor main body 10, the four-way valve 20 and the fastening mechanism are all located in the vibration isolation and noise reduction cylinder 30, and the fastening The mechanism includes an installation assembly for installing the four-way valve 20 and a fastening belt 40, both ends of the fastening belt 40 are connected to the installation assembly, and an adjustable gap is formed between the fastening belt 40 and the installation assembly. The sleeve part 44 , the installation assembly is fixed on the shell of the compressor main body 10 through the fasten...

Embodiment 2

[0054] Such as Figure 5 As shown, the difference from Embodiment 1 is that the two through pipes 47 connected to the heat exchanger on the four-way valve 20 are spirally arranged to form the first shock absorber 61 and the second shock absorber 62 respectively. In this embodiment , the first damping tube 61 and the second damping tube 62 are arranged in a circular spring shape, the first damping tube 61 and the second damping tube 62 are coiled outside the compressor main body 10, the first damping tube 61 and the second shock absorbing pipe 62 are set up and down correspondingly, one end of the first shock absorbing pipe 61 is connected to the first port 23 of the four-way valve 20, and the other end protrudes from the vibration isolation and noise reduction tube 30, the second One end of the vibration damping pipe 62 is connected to the second interface 24 of the four-way valve 20 , and the other end protrudes from the vibration isolation and noise reduction cylinder 30 . ...

Embodiment 3

[0058] Such as Figure 6 As shown, the difference from Embodiment 1 is that the vibration and noise reduction device also includes an expansion valve 70, the expansion valve 70 is arranged in the vibration isolation and noise reduction cylinder 30, and the expansion valve 70 has a third connection with the heat exchanger. The interface and the fourth interface, the third interface and the fourth interface are connected with a connecting pipe 71 , and the connecting pipe 71 protrudes from the vibration isolation and noise reduction cylinder 30 . Since the expansion valve 70 is working, the internal orifice produces fluid whistling sound, and the expansion valve 70 is also arranged in the vibration isolation and noise reduction cylinder 30, which can isolate the noise generated by the expansion valve 70, thereby further improving the performance of the air conditioner refrigeration system. Noise reduction effect.

[0059] This embodiment also provides a method for operating a v...

Abstract

The invention discloses a vibration and noise reduction device and an operation method thereof. The vibration and noise reduction device comprises a compressor body, a four-way valve, a fastening mechanism and a vibration isolation and noise reduction cylinder. The four-way valve is provided with an exhaust connector and an air return connector, and the exhaust connector and the air return connector are both connected with the compressor body through pipelines. The compressor body, the four-way valve and the fastening mechanism are all located in the vibration isolation and noise reduction cylinder. The fastening mechanism comprises an installation assembly used for installing the four-way valve and a fastening belt, the two ends of the fastening belt are connected with the installation assembly, and a size-adjustable sleeving part is formed between the fastening belt and the installation assembly. And the installation assembly is fixed on a shell of the compressor body through the fastening belt. The device can reduce the vibration amplitude of the four-way valve, is favorable for protecting the pipelines and avoiding fatigue fracture of the pipelines, and meanwhile can effectively reduce the operation noise of a refrigeration workpiece.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to a vibration and noise reduction device and an operating method thereof. Background technique [0002] In the existing split-type air conditioner, the compressor is fixed on the base of the outdoor box, the four-way valve is suspended in the air, the exhaust port and the return air port of the four-way valve are connected to the compressor through pipelines, and the other two ports of the four-way valve are connected to the compressor. are connected to the indoor heat exchanger and the outdoor heat exchanger respectively. Since the four-way valve is a suspended mass body, when the compressor is running, the four-way valve is like a rattle in the air, vibrating strongly, which may easily lead to fatigue and fracture of the pipeline. In addition, the compressor, four-way valve and connected pipes are exposed, which become the source of acoustic vibration, makin...
