Project
In the course of constructing its new company headquarters in Neumarkt, the client made a short-term decision to integrate the previously existing decentralised, building-related heating and cooling generation system in a centralised power centre. As in the case of the new administration building, high ecological standards were set in constructing the centralised power centre.
Task
The challenge was to centrally integrate the heating and cooling system in a combined system consisting of trigeneration (vegetable-oil cogeneration) and a biomass boiler (pellets) to serve both the administration and the production buildings. Power generation and cooling were to be set up redundantly (server rooms for worldwide Bionorica data network).
Solution
Power centre consisting of
- 1 vegetable oil-cogeneration system (100 kWel/140 kWth) including emergency power facility (for server rooms and periphery)
- 1 pellet boiler 450 kW
- 1 pellet boiler 545 kW
- Process steam as redundancy
- 4 absorption chillers, YAZAKI, WFC-SC 30
Technical data of the installed YAZAKI absorption chillers
- 4 YAZAKI Li-Br absorption chillers, type WFC-SC 30
- 105 kW refrigeration output (max. 140 kW)
- Hot water: 88 to 83 °C (inflow min. 70 °C / max. 95 °C)
- Volume flow rate varying between 20 and 100 %
- Cold water: 12.5 to 7 °C (outflow min. 5.5 °C)
- Cooling water: 31 to 35 °C (inflow min. 24 °C / max. 34.5 °C)
- COP: 0.7 to 0.78
