Embodiment Construction

[0030] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0031] The natural frequency of the air-conditioning pipeline is related to its structural design and weight. Changing the weight of the pipeline will adjust the natural frequency accordingly. A counterweight can be added to the pipeline as a control variable for the change of the pipeline weight. However, if the weight of the counterweight is fixed, only the natural frequency of the pipeline can be fixed. In the inverter compressor air-conditioning unit, it will also cause the natural frequency of the compressor and the pipeline to overlap and cause resonance.

[0032] In a preferred embodiment, the present invention provides a pipeline stress and strain adjustment device, comprising: a pipeline 1 and an electromagnetic element 2, the electromagnetic element 2 applies electromagnetic f...

Abstract

The invention discloses a pipeline stress strain adjusting device and a method and an air conditioning device. The pipeline stress strain adjusting device comprises a pipeline and an electromagnetic element, and the electromagnetic element applies electromagnetic force to the pipeline so as to change inherent frequency of the pipeline. According to the pipeline stress strain adjusting device, theweight of a counterweight is made to be adjustable, so that the inherent frequency of the pipeline is guaranteed not to be overlapped with running frequency of a variable-frequency compressor. The pipeline stress strain problem of an external unit of the variable frequency air conditioner can be effectively solved, and the pipeline stress strain adjusting device has advantages of being efficient,fast, and free of affecting the capacity of the compressor and the like.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a pipeline stress and strain adjustment device, method and air conditioning device. Background technique [0002] The pipeline of the external unit of the air conditioner is connected to moving parts such as the compressor, causing the pipeline to vibrate with the compressor. If the stress and strain value of the pipeline is large when tested with an instrument, it may lead to risks such as pipeline breakage and leakage. The stress and strain of the pipeline of the inverter air conditioner unit are related to the vibration transmission of the compressor and the pulsation of the refrigerant air flow. The vibration of the air conditioner compressor is a very important factor for the large stress and strain of the pipeline. [0003] The pipeline of the inverter air conditioner has a natural frequency due to its own structural shape and pipeline quality. When the natural fre...
