Abstract

The invention discloses a buffer device and an air conditioner outdoor unit with the buffer device. The buffer device comprises a shell and annular first buffer pieces, wherein a cavity is formed in the shell, the two ends of the shell are provided with openings respectively, the first buffer pieces are arranged in the shell and close to at least one of the two openings, a first air flow passageway is arranged in each first buffer piece, and the area of the cross section of each first air flow passageway is smaller than the size of the cross section of the portion, close to the installation position of the corresponding first buffer piece, of the cavity. According to the buffer device, the first buffer pieces are arranged in the openings of the shell, when air flows into the cavity from the first buffer pieces or flows out of the chamber to the first buffer pieces, the air flow firstly flows through the first air flow passageways limited by the first buffer pieces, the non-reflection condition of air flow pulsation is met, standing waves of air flow pulsation are changed into traveling waves, and therefore the unevenness of pressure pulsation is lowered, abnormal noise produced by air flow pulsation of a compressor is reduced, and the abnormal noise generated by the air conditioner outdoor unit is prevented from being transmitted to an indoor unit.

Description

technical field [0001] The present invention relates to the technical field of refrigeration equipment, in particular, to a buffer device and an air conditioner outdoor unit with the same. Background technique [0002] The noise sources of the air conditioner compressor mainly include mechanical noise, gas dynamic noise and electromagnetic noise. In order to quickly cool or heat, the operating frequency of the inverter air conditioner is high. The gas flows out of the nozzle or orifice at a high speed, impacts and entrains the surrounding ambient gas, forming a violent disturbance, thereby radiating strong noise, and the abnormal sound of the compressor is easily transmitted to the indoor unit through the air conditioner connecting pipe. In order to reduce the abnormal sound of airflow pulsation, multiple mufflers are usually installed in the four-way valve part of the air conditioner, which not only reduces the manufacturing efficiency, but also increases the cost. Conten...
