THEORETICAL AND EXPERIMENTAL INVESTIGATION OF A SINGLE-STAGE POSITION DISPLACEMENT COMPRESSOR WORK PROCESSES WITH A TWO-PHASE WORKING MEDIUM

摘要

At the present time one of the main ways to increase the operation efficiency of the positive displacement compressors is to improve the cooling of the gas to be compressed. It can be gained by injecting the cooling liquid drops into the compressed air. The analysis carried out on the existing methods of calculation of the work processes revealed some drawbacks, such as: 1. discharge, suction and expansion processes have not bee considered at all; 2. the assumptions taken do not give a full agreement with the experimental data; 3. the work spent on the liquid injection was neglected.
