据美国制冷专家的预测,随着科技水平的提高,世界制冷技术将会有新的进展,进入新的领域,其发展动向有以下3方面:1.新材料被广泛应用。新的致冷剂氯氟碳化物将加速替代氟里昂。制冷润滑油也将更新,其粘度/温度系数更适于高温、高速的压缩机。无润滑油的全陶瓷压缩机也将有可能问世。2.新机械被大批推广。旋转式、螺杆式、涡漩式和摆线式4种压缩机进入实用阶段。驱动 According to the prediction of American refrigeration experts, with the improvement of science and technology, the world refrigeration technology will make new progress and enter new fields. Its development trend has the following three aspects: 1. New materials are widely used. The new refrigerant, chlorofluorocarbons, will accelerate the replacement of freons. Refrigeration oil will also be updated, its viscosity / temperature coefficient is more suitable for high temperature, high speed compressor. No oil-based ceramic compressors will also be possible. 2. New machinery is widely promoted. Rotary, screw, scroll and cycloid four kinds of compressors into the practical stage. drive
