摘要
空调通风系统产生的噪声对人们的生活、工作等有着不容忽视的影响,为达到室内的舒适环境,消除空调噪声非常重要。采用半消声室法测试了不同风速、不同消声玻璃棉密度下的标准声源消声器末端噪声,通过与空管标准声源消声器末端噪声比较,求得待测消声器的插入损失。实验结果表明:阻性消声器对中高频的噪声有着良好的消声作用,而消声棉密度在48K时消声器的消声效果最好;同一台消声器在0 m/s^10 m/s风速范围内,消声量变化不大。
For evaporative cooling region of the adapt to the wet bulb temperature of yulin in a market analysis of evaporative cooling system design, in meet the indoor personnelⅠlevels of thermal comfort when using evaporative cooling air conditioning with traditional air supply way, leads to the duct area is too large due to the large air output, unit equipment takes up more space, in turn, affects the popularization and application of evaporative cooling air conditioning technology.In the same grade meet the indoor personnel Ⅰ thermal comfort level, the combination of evaporative cooling and layer ventilation air supply mode, can greatly reduce the delivery system, reduce the area of machine room and duct, increase the universality of evaporative cooling air conditioning applications.
