摘　　要：目前空调室外机通常被安装在建筑高层凹坑或办公楼的设备间中,与用户距离较近,其高运行噪声对用户的工作和生活产生了直接的影响,干扰了用户正常的生活和工作状态,而整机风噪较高是导致空调运行噪声高的主要原因之一。基于测试与仿真结合的技术构建了针对整机风阻高、风机噪声大等现存问题的风扇风道耦合减阻降噪改善方法,包括中隔板形状优化、出风格栅减阻等。通过对手板样件的风量、噪声验证试验发现,在同风量下,采用耦合减阻降噪的方法设计风扇风道可以使整机风阻降低5 Pa、整机风噪降低1.4 dB(A)。优化分析结果对空调室外机的风扇风道的提效、降噪设计具有一定指导作用。At present,the outdoor unit of air conditioning is usually installed in the equipment room of office buildings or high-rise pits,which is close to the user.Excessive operating noise has a direct impact on the user's work and life,and will also cause user complaints and increase the company's operation and maintenance costs.The high aeroacoustics wind noise of the whole machine is one of the main reasons for the high noise of air conditioning operation.Constructs an improved fan-duct coupling method for drag reduction and noise suppression including shape optimization of middle baffle and drag reduction of outlet grills and so on based on the combination of test and simulation,aiming to solve the currently existing problems such as high aerodynamic drag and hyper aerodynamic noises.According to the sample’s air volume and noise experiments reports,the aerodynamic drag and noise of the as-designed machine sample was reduced by 5 Pa and 1.4 dB(A)under the same test conditions,respectively.The optimization analysis results have a certain guiding effect on the efficiency improvement and noise reduction design of the fan duct in the air conditioner outdoor unit.
