The high efficiency of turbocompressors makes them ideal for supplying larger mines with com-pressed air. As the gas flows through the compressor, the pressure increases, generating a large amount of heat. This heat needs to be removed, and this is usually achieved through cooling towers and it ultimately escapes into the surroundings as waste heat. This article aims to study the recovery and possible use of this waste heat.
