Abstract
The climatic conditions of Uzbekistan are characterized by relatively long summers with air temperature of 40-45 0C and higher, which is the reason of significant heating of air suctioned by compressor. Increase in temperature and corresponding decrease inair density contributes to 8-10% decrease in compressor unit productivity, leading to significant economic losses in the process of compressed air production. By means of artificial cooling of suction air at the inlet to the compressor unit it is possible to increase the energy efficiency of operation of the mine reciprocating compressor unit.The effectiveness of artificial air temperature reduction depends on the amount of temperature reduction and the type of plant drive, as well as on the purpose -toreduce the specific electric energy consumption for compression or to increase the capacity of the reciprocating compressor.
