JB/T 5446-1999 本标准是对 JB/T 5445-91《中型活塞式单机双级制冷压缩机 型式与基本参数》、JB/T 5446-91《中型活塞式单机双级制冷压缩机 技术条件》和 ZB J73 005-89《活塞式单机双级制冷压缩机 试验方法》的修订,其主要技术内容改变如下: ——删除了有关 R12 的参数和技术要求; ——增加了缸径 100mm、行程 70mm 系列的参数和要求; ——噪声测定改为先测声压级再换算成声功率级; ——型号表示方法改变。 本标准规定了活塞式单机双级制冷压缩机(以下简称压缩机)及活塞式单机双级制冷压缩机组(以下简称压缩机组)的术语,产品分类,技术要求,试验方法,检验规则,标志、包装和贮存。 本标准适用于以 R22、R717 为制冷剂,气缸直径为 70~170mm 的压缩机和压缩机组。 采用其他制冷剂的压缩机的压缩机组可参照本标准。


Scope

This standard specifies the terminology, product classification, technical requirements, test methods, inspection rules, marking, packaging and storage of piston single-machine two-stage refrigeration compressors and piston single-machine two-stage refrigeration compressor units. This standard applies to compressors and compressor units using R22 and R717 as refrigerants and with cylinder diameters of 70 to 170 mm. Compressor units using compressors using other refrigerants may refer to this standard.
