摘　　要：以实际工程为例,介绍了在大型风冷冷水机组性能试验室中如何进行试验室声学设计,在满足大型风冷机组性能试验的基础上,在兼顾工况试验所需要的温度变化、湿度变化以及气流组织需要的同时,考虑噪声测试的特殊需要,采取合理组织气流走向等技术措施,保证大型空调冷冻设备性能试验室内的声场效果达到预期要求。Acoustic design of a large tonnage air-cooled chiller performance test facility is described. Performance test is carried out to meet the basic requirement of the air-cooled chiller.In the mean time, variations of temperature and humidity, suitable air flow, and requirements for noise test are taken into account.In this way the designed anechoic test chamber can provide desired results that meet the expected specifications.
