摘要
精密空调室外机运行时通常产生较大的噪声,会对周围区域产生影响。为解决某办公大楼精密空调室外机对楼内办公室和周边居民区产生的噪声问题,对现状进行了分析,设计了改造方案,通过三维建模和仿真计算分析了该方案在隔声降噪、空气流场、温度场变化等方面的特点和可行性。该方案不仅解决了噪声问题,同时还保证了室外机的安全稳定运行。对比改造前、后的测试数据,结果表明改造后效果良好,办公室内背景噪声和传到居民区的噪声均达到国家规范标准。研究结果对精密空调室外机的隔声降噪工程应用具有一定的指导意义。
Precision air conditioner outdoor units typically generate significant noise during operation,which can have an impact on noise level in the surrounding area.In order to solve the noise problem in an office building and surrounding residential areas caused by precision air conditioner outdoor units,the current situation is analyzed,and the renovation plan is designed.The characteristics and feasibility of this plan are analyzed through three-dimensional modeling and simulation calculation in terms of sound insulation and noise reduction,air flow field,temperature field changes,and other aspects.The solution can not only solve the noise problem,but also ensure the safe and stable operation of the outdoor unit.Finally,comparing the test data before and after the renovation,it is shown that the effect after the renovation is good,and the background noise in the office and the noise transmitted to residential areas both meet national standards.The research results have certain guiding significance for the sound insulation and noise reduction engineering application of precision air conditioner outdoor units.
