开启式螺杆制冷压缩机的外型是压缩机布局的直接反映， 有必要进行进一步的分析。根据 出轴端在吸气侧或排气侧， 大体上可把开启式螺杆制冷压缩机分成两种型式。在螺杆式制冷压缩 机发展的初期， 外型不很重要， 但如今出轴端在吸气侧的型式更好。
Open screw refrigeration compressor shape is a direct reflection of the compressor layout, it is necessary for further analysis. According to the output shaft side of the suction side or exhaust side, generally open screw compressor can be divided into two types of refrigeration compressor. In the early stages of the development of the screw refrigeration compressor, the appearance is not very important, but now the type of shaft in the suction side is better.
