Refrigerating device

Abstract

The invention discloses a refrigerating device. The refrigerating device comprises a box body base plate, a compressor and a limiting support, wherein the compressor is arranged on the box body base plate; and an upper limiting block for limiting the upward vibration amplitude of the compressor is arranged on the limiting support. According to the refrigerating device in the embodiment of the invention, the limiting support and the box body base plate are matched to limit the up-down vibration amplitude of the compressor, realize vibration attenuation of the compressor in the operating, transporting and falling processes, avoid excessive stress of a pipeline, and also avoid excessive stress of a connected part between the compressor and the box body base plate, thereby avoiding the phenomena of pipeline breaking, and tearing or deformation and separation and the like of the connected part between the compressor and the box body base plate due to impact load or fatigue load.

Description

technical field [0001] The invention relates to the field of refrigeration equipment, in particular to a refrigeration device. Background technique [0002] The compressor is the core component in the air conditioning and refrigeration system, and it is also the main source of vibration in this system. During the operation of the compressor, there will be relatively severe vibration excitation, which will stimulate the structural vibration of the shell chassis and even the entire system, resulting in high noise and damage to the structure of the refrigeration system. [0003] In order to solve this problem, the general method is to add a vibration damping structure between the compressor and the shell chassis, and reduce the vibration excitation transmitted from the compressor to the shell chassis by means of vibration isolation, thereby reducing the noise level of the entire system and vibration response. [0004] However, the means of vibration isolation will also produc...

AI Technical Summary

Problems solved by technology

[0004] However, the means of vibration isolation will also create some new problems.

For example, during transportation, if the energy excited by the external transportation falls within the frequency range of the compressor vibration-damping structure and the compressor combined system, the system composed of the compressor and the vibration-damping structure is prone to resonance, which will lead to Larger vibration occurs in the compressor pipeline and four-way valve, which may cause structural damage or even breakage of the compressor pipeline during transportation

Another example is that during the operation process, the pulse excitation generated by the start and stop of the compressor will inevitably stimulate the large vibration of the compressor damping structure and the compressor combined system, which will lead to large start-stop stress and fatigue damage of the compressor pipeline , with the accumulation of use time, the compressor pipeline may also be broken
