Electrical energy is supplied to the compressor for compression. As much as ~95% of this valuable energy is converted into waste heat.
It consists of waste heat from the drive motor, waste heat from cooling the compressed air and waste heat from lubricating oil cooling.
This ~95% is available for heat recovery and can be used.
The rest, ~4%, remains as heat in the compressed air. ~1% is lost through heat radiation.
Heat recovery serves with rising energy costs, political dependence on energy source imports and increasing climate protection for the heating of rooms, of service and heating water.
The usable energy increases with the number and size of the compressors and depends on their duty cycle in order to provide sufficient heating power according to the heat demand.
