Synergo Heat Reuse Systems: High-Efficiency Solution
The same Synergo modules that cool the data hall can simultaneously run in heat-pump mode, lifting rejected heat to temperatures useful for district heating or facility use — up to 95°C hot water in Heat Export Mode, or 65°C+ on standard modular-chiller heat-reuse duty. An intelligent Sequencer assigns each module's role — Chiller Mode or Heat Pump Mode — in real time, so the plant can run anywhere from 100% cooling / 0% heat recovery to 100% cooling / 100% heat recovery, without compromising the chilled-water supply to the IT load.
Key points
- Hot water supply, Heat Export Mode: Up to 95 °C
- Integral heat-reuse hot water, standard chiller: +65 °C
- Heat Export Mode maximizes heat recovery at high condensing temperatures, prioritizing thermal energy export over pure cooling efficiency when a heat off-taker is available.
- Reference Project: Simultaneous cold + hot (10 MW) and District heating supply temp. of 75 °C (Case Study: 10 MW Data Center in Denmark with 12 Frigel's Synergo)
- Regulatory Tailwind: The EU's revised Energy Efficiency Directive requires data centres above 500 kW to report energy performance, with minimum sustainability standards expected and a climate-neutral goal by 2030; centres connected to district-heat networks benefit from specific exemptions.
