Theoretical analysis of the temperature conditions for a long-stroke low-speed piston compressor stage under the intensive external cylinder cooling and increased gas temperature at the standard suction point

The paper considers relationship between the temperature at the end of the compression process and the gas average discharge temperature at the compression process start and at the standard suction point for the different cylinder diameters and working cycle periods for a long-stroke low-speed piston compressor stage. The theoretical analysis results prove a fundamental possibility of implementing the subisothermal compression process for small cylinder diameters, where the working gas temperature at the end of the compression process is lower than at the beginning, and the conventional polytropic index of the compression process is less than one. The compression process is quasi-isothermal in nature with the compression conventional polytropic index slightly exceeding one, which corresponds to the previously obtained results. The average discharge temperature in this case is significantly lower than the temperature at the standard suction point, which reflects features of the stage under consideration and makes it possible to assume a possibility of its use as a booster without preliminary cooling the suction gas, including as part of the mobile compressor systems.
