Description

Technical fields:

[0001] This invention belongs to the field of thermally driven gas pressurization technology. Background technology:

[0002] In thermally driven gas thermal pressurization systems, compressors and expanders are essential core components. Through years of theoretical research and engineering practice, and after in-depth consideration and careful analysis, we have found that:
