Case studies

  • A cost-effective solution: district cooling in central Copenhagen
    A cost-effective solution: district cooling in central Copenhagen

    Energy efficiency was a major consideration in the design of Copenhagen’s district cooling project, where VLT® drives contribute to reducing CO2 emissions by more than 3000 t annually.

  • Solar heating plant reduces CO2 emissions by 15,700 tonnes annually
    Solar heating plant reduces CO2 emissions by 15,700 tonnes annually

    The world’s largest solar heating plant in Silkeborg, Denmark harnesses energy to heat the homes and workplaces of 40,000 citizens. It supplies 18-20% of the annual heat consumption in the city of Silkeborg, Denmark, which has an ambitious target of CO2 neutrality in heat production by the year 2030.

  • District energy as the heating and cooling solution in Teknopark Istanbul, Turkey

    Building: Office
    Application: Production of heating, cooling and domestic hot water
    Challenge: Design and construct customized district energy solutions for all buildings on the park
    Solution: Danfoss  designed and constructed 3 pre-assembled DSE substations containing control valves for the heating, cooling and domestic hot water, heat meters, self-acting controllers and electronic controllers connected to a central Building Management System. 

  • Heating facility reconstruction in Kopaonik mountain resort, Serbia

    Building: Hotel
    Application: Hydronic balance, control and monitoring of a heating system
    Challenge: Improve the energy efficiency of old heating system
    Solution: Danfoss installed motorized control valves, hydronic balancing valves and electronic controllers with monitoring software

  • Renovation of a district heating network, Tuzla, Bosnia and Herzegovina

    Since 2011, the local District Heating Company (“Centralno grijanje” d.d. Tuzla) has carried out a major renovation of the city’s comprehensive district heating network, providing reliability of supplies, improved comfort as well as energy and cost savings. Based on thorough analysis and a long-term strategic approach, the 30 year old system is gradually transformed into a modern and smart energy system.

  • First ever district heating system with substations in Turkey

    600 residents in the town of Soma in Western Turkey now enjoy the comforts of a reliable and cheap heat supply from the town’s brand new district heating system. 

    In the coming years, more than 8,000 households will be joining the system that exploits the excess heat from the municipal power plant – a great improvement from the charcoal boilers of the past, and much less expensive.
