本系列的4种产品是我国《中小型活塞式单级制冷压缩机型式与基本参数》规定的国家系列产品的一部分。它们的共同特点是重量轻、体积小、效率高、另件通用性强、互换性好,改变少量零件能适用NH_3、F22和F12等三种工质,用于单级压缩机,也可使几台机器按比例配合,成双级压缩、作低压和高压机使用。它广泛应用于化学、石油、制药、食磊工业、工矿企业、影剧院、大会堂等大型建筑的
This series of 4 kinds of products is China’s “small and medium-sized single piston compressor refrigeration type and basic parameters” provisions of the national series of products. Their common feature is light weight, small size, high efficiency, the other versatile, good interchangeability, change a small number of parts can be used NH_3, F22 and F12 and other three kinds of working fluid for single-stage compressors, but also Make several machines match proportionally, into two-stage compression, for low pressure and high pressure machine use. It is widely used in chemical, petroleum, pharmaceutical, food industry, industrial and mining enterprises, theaters, conference halls and other large buildings
