未来用于空调和制冷的双螺杆压缩机 （美）（原文第1页） 对世界范围的双螺杆压缩机的总的发展趋势及其要求的 预测表明了未来工业上使用的双螺杆压缩机的一个值得注意 的重要变化。 工业上的成本竞争历来激烈,仅此事实就巳经引起了许 多别的设想,即关于双螺杆压缩机用于何处才真正合适,特别 是在世界上空调设备大规模增长的情况下。3吨或3吨以上 的大型压缩机通常以往复式压缩机占统治地位.但涡旋压缩机在尺寸规格增大方面的迅速渗透,也是十分引人注目的。 未来在什么地方适合用双螺杆压缩机,为什么用它们? 本文就多种不同的情况与需求进行了研究并试图评价它们对 未来工业上使用的双螺杆压缩机可具有的意义。具有代表性 的探讨项目如下:
Future twin-screw compressors for air-conditioning and refrigeration (United States) (Original page 1) A general forecast of the global trends and requirements for twin-screw compressors worldwide shows that the twin-screw compressors used in the industry in the future A noteworthy important change. The fact that industrial cost competition has always been intense has led to many other ideas that have made it really appropriate where twin screw compressors are used, especially given the massive growth of air-conditioning equipment in the world. Large compressors of 3 tons or more often dominate reciprocating compressors, but the rapid penetration of scroll compressors in increasing size is also noticeable. Why use twin-screw compressors in the future and why? In this paper, we investigate a number of different situations and needs and try to evaluate their implications for the twin-screw compressors used in the industry in the future. Representative discussion items are as follows:
