DISTRICT HEATING & DISTRICT COOLING ENGINEERING

Stress calculations, hydraulic modelling and engineering consultancy

EnergyMentor provides advanced engineering services for district heating and district cooling networks, supporting utilities, engineering companies and contractors throughout the entire project lifecycle.

Our expertise combines practical pipeline engineering with professional modelling tools to deliver reliable, efficient and cost-effective infrastructure solutions.
STRESS CALCULATIONS
Reliable pipeline design under real operating conditions
EnergyMentor performs stress calculations for both above-ground and buried district heating and district cooling pipelines. Using industry-leading engineering software such as sisKMR and ROHR2, we evaluate thermal expansion, operational loads and installation conditions to ensure long-term pipeline reliability and compliance with EN 13941.

Our services include:
  • Thermal expansion analysis
  • Stress calculations for buried and above-ground pipelines
  • Expansion loop and compensation design
  • Support and anchor load calculations
  • Verification according to EN 13941
  • Pipeline route optimisation
  • Independent engineering review
Our calculations help minimise mechanical stresses, prevent failures and optimise construction costs throughout the project lifecycle.
HYDRAULIC MODELLING
Optimising district heating and cooling networks
EnergyMentor performs hydraulic calculations and thermo-hydraulic simulations for both new and existing district heating and district cooling systems. Using Danfoss Leanheat Network, we analyse network performance under different operating scenarios and identify opportunities to improve efficiency and reliability.

Our services include:
  • Hydraulic modelling of DH and DC networks
  • Pipeline sizing and pressure-loss calculations
  • Pump selection and optimisation
  • Network balancing
  • Integration of renewable and excess heat sources
  • Scenario analysis for network expansion
  • Identification of hydraulic bottlenecks
  • Energy efficiency optimisation
Accurate hydraulic modelling enables better investment decisions, lower pumping energy consumption and improved network performance.
