Distribution network:  Safe, sustainable and scalable

A district energy network is extremely flexible and can be used to connect as few as 30-40 houses. This allows cities to grow an existing network as funding, planning and other opportunities become available.

Efficient operation of the district heating network requires that the entire value chain from generation, distribution and usage is designed and maintained to be optimum balance.

Danfoss’ many years of experience can help you with designing the optimal district heating network, whether you are starting from scratch or renovating an existing district energy network.

Network design

Optimal network design is key to an economically fit district energy network. Therefore we utilize the network thermo-hydraulic model to avoid over-designing and to verify capacity and impact on the whole network. This means that by installing proper control equipment you can benefit from network balancing and therefore lowering your initial investments. The control components and hydraulic model will also enable ∆T optimization which will ensure system efficiency and reduction of primary energy generation cost, as supply temperature will be optimized, and temperature and flow can be balanced in real time.

Planning the optimal fuel-mix

In heat production the utilization of various heat sources can be optimized by planning the optimal fuel-mix. District heating technology makes use of a wide variety of energy resources:

  • Boilers using conventional or renewable fuels such as biomass;
  • Heat from power generation such as a Combined Heat and Power plant;
  • Waste heat from industrial processes;
  • Energy generated from municipal waste incineration;
  • Natural heat sources such as solar, geothermal or wind. 

Responding to peak energy demand

Also when it comes to peak energy demand Danfoss can support you with expertise and production simulation to enable smart district energy production and distribution planning. This will secure maximum utilization of heat accumulation in buildings and networks.
