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 of oil free scroll compressor during me trial on designing a oil-free scroll compressor as my graduation thesis. Here, zhangpeng want to share my experiences on oil-free scroll compressor. This result is a combination of books and research papers. I reconfigured each step in order to get a right result in shorter time. » Read more
