Decarbonization with integrated cooling and heating energy systems

Decarbonization with integrated cooling and heating energy systems and heat recovery

Join Drew Turner as he breaks down the art of merging diverse energy sectors to boost efficiency and drive decarbonization efforts.  Learn about the innovative, yet practical ways to harness this strategy, like repurposing excess heat from cooling systems for heating needs elsewhere. You’ll also discover the potential of integrating renewable energy sources into the power grid, while addressing the challenge of supply-demand equilibrium.

Trends driving district energy

The shift in the district energy sector from single source to multi-source, from fossil fuels to renewables and surplus energy, and from high temperature to low temperature district heating, brings with it several key challenges.

Danfoss end-to-end district energy solutions deliver actionable insights enabling continuous optimization and optimal temperature control on both demand and supply side.

Let’s unlock the potential of district heating

Can existing supply chains handle increased pressure?  Is there a way to develop networks effectively while delivering safety and comfort for the end user? Moreover, how can we maximize the use of renewable resources to deliver reliable and safe heating? If you are wondering what district energy means for your network operation or planned renovation, listen to the recording from our live stream.

End-to-end optimization

Addressing main challenges in district energy

Hydronically unbalanced systems result in high flow and high return temperatures. ∆T directly impacts heat production cost and efficiency, distribution network cost and efficiency. Challenge in district energy is how to maximize network and production efficiency while providing best quality of supply.

Our solution

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.

Water & heat losses, shift of critical points in network, extensions of the network and many other factors cause high cost of production due to poor planning. Challenge in district energy is how to minimize investment cost and maximize consumption density making optimal network dimensioning and economically prioritized investments.

Our solution

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.

Decentralization and increased fuel complexity make integration and forecasting much more difficult. Challenge in district energy is how to maximize utilization of production sources with best economy and efficiently manage complex networks while still improving utilization of various heat sources with best economy investments.

Production of heat from renewables can be prioritized and better controlled, helping the utility to be spot on (or above) the target.

Our solution

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.

Regulative for energy savings demands yearly energy savings and clear documentation proving those. Challenge in district energy is how to achieve end-user energy savings target and invest to secondary heating side to improve efficiency of the primary side. Goal is to make smart investments.

Our solution

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).

Peak heat load and expensive peak fuels stretch DHU resources and make heating more expensive for both DHUs & end users. It has also a high effect on CAPEX as well as OPEX. Challenge in district energy is how to lower the effect of peak energy demand on network operation costs and cover peak demand with regular heat sources while lowering investment and operating costs.

Our solution

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.

Legacy SCADA systems make data integration difficult and time consuming. Challenge in district energy is how to make data integration easier and less time-consuming while lowering investment and maintenance cost.

Our solution

Solution is to save time and money by using modern SCADA with:

  • Open database access
  • Open connectivity
  • Auto-generated key process and performance indicators
  • Auto commissioning functions

All of the above remedies will help unlock your hidden resources and should add up to 30% improved efficiency compared to traditional SCADA.

Challenge in district energy is how to extend customer services provided by DHU and increase customer perception of DHU as reliable, transparent and flexible partner.

Our solution

Solution is to position DHU as an expert in energy efficiency and make it an obvious choice for energy supply towards end user by:

  • Providing additional services e.g. safety monitoring and maintenance contracts;
  • Providing supportive tools e.g. Enspire and Heat Selector;
  • Providing training and recommendations towards secondary system modernization;
  • Providing solutions for system modernization and optimization.

This will support integration of primary and secondary side and increase customer’s satisfaction.
 

Challenge in district energy is how to cope with increased competition in district heating segment, develop new business areas to secure profitability and don’t miss the digitalization train.

Our solution

Solution is to position DHU as an expert in energy efficiency and make it an obvious choice for energy supply towards end user by:

  • Offer heating bills reduction and maintenance optimization;
  • Offer full package solution for secondary side, including equipment (Enspire, TRV, stations, ASV).

With all this, DHU can improve competitiveness and increases profitability by using new sales channel. In the end, DHU will be up-to-date and profitable.
