The role of Veolia Industries Austria in this project
- Planning
- Realisation and technical project management
- Maintenance and servicing of the system during operation
- Ongoing optimisation
Initial situation
The heat from a cooling water circuit (45 °C) was not utilised.
At the same time, natural gas was burnt to support an internal heating system.
Goal
Utilising the energy of the cooling water for heating purposes by raising the temperature with a heat pump
Solution
Installation of a water/water heat pump
The previously unused energy is extracted from the cooling water and fed into a 90 °C heating system.
Further technical details
Thermal output: 1.500 kW
Refrigerant: environmentally friendly ammonia (R-717)
COP: 5,5
Benefit
Reduction in annual CO² emissions by approx. 1,700 tonnes
Annual natural gas consumption reduced by approx. 700,000 Nm³ per year
