压缩机中的英文单词Polytropic? 针对压缩机来说,其实就是“多级的”,而且级间带有冷却系统,而不是绝热或等温压缩过程。下面是对几种类型的压缩过程的定义: if gas is compressed, then cooled , then compressed again, the process is called polytropic compression. polytropic means ‘many stages’. if heat is added or taken away to maintain the gas at a constant temperature, the process is called isothermal compression. if no heat is added or taken away during compression, the process is called adiabatic compression.
