Research situation of oil free air scroll compressor
Scroll compressor was created at 1905, by a French engineering Leon Creux. But as the technology of the period was not advanced to construct a working product, first practical scroll compressors did not appear on the market until 1980s. Since 1970s, the energy crisis and the appear of high precision CNC milling machine brings the [...]

Calculation of oil free scroll compressor
Scroll compressor was created at the beginning of 1900s. Due to the limitation of processing technology, there are no product before the 1970s. Now the scroll compressor is the major compressor used by air conditioning. However, there are still many technology shortages of oil-free scroll compressor. I find it hard to get the right equations for calculation [...]

无油润滑涡旋压缩机设计计算步骤
涡旋压缩机从20世纪初提出，此后由于加工技术的局限，一直到70年代才开始发展，而无油涡旋压缩机的技术出现更晚，由于其泄漏问题也限制了无油涡旋压缩机的发展。目前虽然涡旋压缩机已经占领了空调市场，无油涡旋压缩机技术仍然不够成熟，国内生产无油涡旋压缩机的厂家也不多。然而由于

什么是吸附式制冷
这或许是张鹏少量几篇先有英文再有中文的文章之一，主要是因为是在一个英语教学课上要用到这个PPT，所以就先有英文版的咯。 吸附式系统包括太阳能集热器、冷凝器、储液器、蒸发器和阀门。 制冷, 科普
