Abstract

The invention discloses a refrigerant noise reduction device and equipment with a refrigeration function. The refrigerant noise reduction device comprises a capillary tube and a vibration reduction magnet assembly located on the outer wall of the capillary tube, wherein the vibration reduction magnet assembly clamps the capillary tube through magnetic force. According to the refrigerant noise reduction device, the vibration reduction magnet assembly is arranged on the capillary tube, so that the capillary tube is reinforced, the additional weight of the capillary tube is increased, and the vibration of the capillary tube is reduced; moreover, the capillary tube is clamped by utilizing the mutually attracted magnetic force in the vibration reduction magnet assembly, so that compared with the prior art adopting cement gum, the vibration reduction magnet assembly is not influenced by low temperature, the magnetic force cannot fade even under the low temperature condition, and the reliability is improved; and meanwhile, compared with the prior art adopting the cement gum, the acting force on the capillary tube is increased, and the vibration suppression effect is improved.

Description

technical field [0001] The invention relates to the technical field of refrigeration noise reduction, and more specifically relates to a refrigerant noise reduction device and equipment with refrigeration functions. Background technique [0002] For equipment with refrigeration function, the noise mainly includes: compressor noise, pipeline vibration noise, fan noise and refrigerant noise. With the continuous advancement of technology, compressor noise and fan noise have been continuously reduced, pipeline vibration noise can also be predicted and resolved, and refrigerant noise has become increasingly prominent. [0003] Refrigerant circulates continuously in the system, and the pressure, temperature and state constantly change, resulting in refrigerant noise, which is mainly manifested in the injection noise caused by the sudden change of state of the refrigerant entering the evaporator after being throttled by the capillary tube. At the interface between the condenser an...
