At the use of the resonant phenomena in the suction system of piston compressor it is succeeded to improve its productivity. In this case, it remains unclear, how the work of compressor and its other characteristics will change. Researches results at influence of resonant fluctuations gas pressure in the suction system on the capacity of the gas stream forced in a pneumatic network, specific work and internal efficiency piston compressor are brought. Exergy analysis of influence of the wave phenomena on the process of receipt of the compressed gas gave an opportunity to estimate advantages of method of intensification of the compressor productivity, to get an objective evaluation indicators of efficiency its use.
