中央空调多联机液流噪音影响因素研究及对策

Study on Influencing Factors and Countermeasures of Multi-line Flow Noise in Central Air Conditioning

家用多联机使用过程中出现的噪音问题,是目前多联机售后投诉的重中之重,但由于多联机空调的控制逻辑复杂性、安装规范性、系统可靠性因素,带来了问题处理的高难度。多联机噪音问题多种多样,其中多联机内机的液流噪音,是所有噪音问题里最难解决的。本文调研了现有主流造成多联机内机液流噪音的各种因素,结合实际处理过程的有效方法经验,分析了各类液流噪音的形成机理、控制关键因素,总结形成有效的系统解决策略。

The noise issues encountered during the operation of household multi-split systems are among the most critical concerns in post-sale complaints.However,the complexity of control logic,installation standards,and system reliability in multi-split Ac units present high difficulties in addressing these issues.Among the various types of noise problems,the liquid flow noise in the indoor units of multi-split systems is the most challenging to resolve.This paper reviews the prevailing factors that contribute to the liquid flow noise in multi-split indoor units.By integrating practical experiences and effective methods from actual handling processes,the paper analyzes the formation mechanisms of various liquid flow noises and identifies the key control factors.Based on this analysis,a systematic strategy is developed to effectively address these noise issues.
