近年来参加了三次风机盘管机组新产品鉴定会,还看到了其他一些厂的产品鉴定书,测定方法大多采用日本JIS A4008—1976,用A计权平均总声压级表示。但是否可参考美国制冷协会标准443—70“风机盘管空调器声级额定标准”,这标准是根据美国采暖制冷空调工程师学会标准36—62所制定。下面想就此对制造厂的测定工作和设计使用单位的应用方法提几点建议。
In recent years, participated in three fan coil unit new product appraisal meeting, but also saw some other plant product appraisal book, most of the measurement methods used in Japan JIS A4008-1976, with A weighted average total sound pressure level said. However, please refer to the American Society of Refrigeration standard 443-70 “fan coil air conditioner rated sound level”, this standard is based on American Institute of Refrigeration and Air Conditioning Engineers standards 36-62 developed. Here to think about this factory on the determination of the design and application of the use of units to make a few suggestions.
