District heating

To solve those challenges, you need to optimize supply temperature, improve ∆T and balance supply temperature and flow. With utilization of intelligent solutions and components system from Danfoss you are able to:

• Improve primary side ∆T by increasing efficiency of the secondary side;
• Achieve optimal balance between ∆T and flow;
• Reduce distribution & production costs.
  
  

It is estimated that due to operation cost reduction and improved efficiency we can achieve min 1% reduction of primary energy generation cost for each 3K of ∆T increase.

To solve those challenges, utilize thermo-hydraulic model to:

• Avoid over-designing;
• Verify capacity and assess impact on the whole network.
  
  

It is estimated that due to use of proper planning at network dimensioning & support with components sizing (consultancy) we could reduce investment for 17% comparing to traditional design.

Solution to those challenges is efficiently production planning (fuel-mix) by utilizing:

• Demand forecast;
• Real time network balancing;
• Heat production simulation.
  
  

With this you will support 27% EU renewable energy target.

Solve those challenges by:

• Sourcing and developing know-how on potential measures and proofing of savings.
• Executing secondary side measures with best cost-performance ration on primary side.
  
  

In the end, you can achieve more than 1,5% of end-user savings annually (EU Energy directive target which is only relevant for countries with obligation schemes).

Solve those challenges by:

• Heat production simulation;
• Maximizing utilization of heat accumulation in buildings and network;
• Executing control measures for heat-up ramping.
  
  

With this you can achieve up to 20% peak energy demand reduction.
