Lower production costs and emissions
The traditional rule-of-thumb approaches for choosing a district heating network’s supply temperature have large margins for actual arrival temperature. The traditional approaches have proven to get the job done, but considerable reduction in thermal losses could be achieved for every degree of reduced supply temperature. Furthermore, if temperatures can be lowered below certain thresholds, completely new waste heat streams may become available as heat sources. However, lowering temperatures in complex district heating networks should be carefully planned, as numerous factors, constraints, and challenges must be addressed.
Consider the overall efficiency
When supply temperatures are lowered, a network’s pumping performance and pipe capacity must also be considered. Consumers draw more flow through their heat exchangers to extract the required thermal energy, thereby increasing the system’s water flow rate. This leads to network pumps operating at higher flow rates, increasing electricity consumption. It’s also essential to ensure that the network’s pipe capacity is sufficient for these higher flow rates.
State-of-the-art pumping station models are implemented in Fluidit Heat, so you can efficiently test different supply temperature strategies and visualize both network pressure losses and pump operating points. The overall feasibility of lowering supply temperatures can be assessed by comparing the savings from reduced heat losses with the additional pumping costs, giving you peace of mind that you are truly optimizing the overall system.
No guessing of arrival temperatures
A fundamental constraint in district heating network operation is that the supply temperature must remain high enough to meet domestic hot water quality standards at all times. Fluidit Heat provides you with an in-depth understanding of your network – whether identifying the most critical consumers, manipulating heat distribution from various sources with valves and pumps, or planning investments to eliminate heat distribution bottlenecks. Having all the answers at your fingertips gives you the power to solve problems before they even happen.
Create your own future
District heating systems are expected to become increasingly integrated with various energy sources and smart control systems. Dynamic supply-temperature management will play an essential role in bringing these flexible, efficient systems online. New source types with varying energy and mass flow configurations and different behavior across network states are conceptually interesting, financially attractive, and typically challenging to evaluate in advance. With Fluidit Heat, you can build any kind of source into your network and see how it would perform. Only imagination is the limit on the ideas you can try – but Fluidit Heat will tell you whether the idea is feasible.
