80 – 105% of the electrical input can be recovered as hot water!
According to the laws of thermodynamics the energy used to compress air is transformed into heat.
The major portion of this heat – more than 90% - remains in the compressed air and lubrication oil. A small part is lost to the environment through radiation.
However, electrical input is not the only source of energy entering the system. The suction air for the compressor contains water vapour. The heat stored in the vapour is released through condensation in the inter- and after cooler of the compressor. Typically the condensation heat, contained in the suction air, is equivalent to 5 - 20% of the electrical input energy.
The unique design of the cooling system of the ZR oil-free screw compressor with energy recovery allows to fully capture all this heat from the compressed air and oil system.
As a result, the total energy recovered as hot water amounts up to 80-105% of the electrical input energy, depending on the site conditions. In most industrial conditions it will be 90 to 95%.
