摘要 分体挂壁空调制冷过程出现制冷剂冲刷声,这种低频声穿透性强、辐射面广,严重影响了使用的舒适性。经过测试体验以及现象分析,发现该声音产生的主要原因是蒸发温度与U管温度差过大,导致制冷剂状态的急剧变化产生的噪音。针对该声音产生的机理,制定了有效的改善措施,通过增加低频停留点,提高蒸发温度,减少制冷剂状态的变化,提高了使用舒适性。 In the refrigeration process of wall-mounted air conditioner, the refrigerant scour sound would appear, which has the characteristics of strong penetrability of low-frequency sound and wide radiating surface, it serious affect the comfort of use. Through the test experience and phenomenon analysis, we found the main reasons causing the noise, that is, the large temperature difference between evaporation and U pipe. The rapid change of the state of refrigerant results in the noise. According to the mechanism of the noise generation, the effective improving measure is proposed. Through adding low-frequency arrest points, it raises the evaporating temperature, reduces the changes of refrigerant states, and improves the comfort of use.
