Your data on the waste heat source

The nominal power can be read on the motor type plate or data sheets.
A air-cooled compressor allows heating via air ducts. e. g. hall heating. The waste heat of a water-cooled compressor can be used to support the heating and to heat up service water or fresh air for a ventilation system.
Partial load operation of a system reduces the amount of waste heat. Estimate what percentage of your system is operating at partial load instead of nominal load.
For power generation, the waste heat source must be operated at rated load throughout the year.
Further information

The system output can be more or less reduced in partial load operation. Determine the respective performance of different partial load conditions and weigh them.

Your data on the intended use of waste heat

Select a waste heat utilization (or a heat exchanger in the room air conditioning system module).
Note: When using heat pumps, additional power is required.
Further information

Depending on the type of waste heat used, enter the number of weeks in which the available waste heat can be used.
For any heating support, the waste heat can only be used during the heating season for the building.

Cost estimates
  • Fuel price:
    • Gas: Net price per kWh (see invoice)
    • Fuel oil: 1 l of fuel oil contains approx. 10 kWh of energy => Net fuel oil price per liter (see fuel bill) divided by 10 gives the price to be entered per kWh.
  • Interest rate: interest rate to be paid on a loan
  • Payback Period: Time period within which the waste heat utilization facility is depreciated.
