LOW- TEMPERATURE DISTRICT HEATING FOR OLD AND NEW BUILDINGS
By Niels Hansen, Senior Consultant, Albertslund Municipality
Albertslund Utility, Denmark, has cracked the code to lower the district heating temperature all over the town. With shunt valves and temperature zones, the utility can lower the temperature in the 60-year- old grid without changing the existing pipes and upgrading the 6-bar net to a 10-bar net. With shunt valves, both the temperatures and the pressure in the grid can be lowered simultaneously. And the flexibility gained by temperature zones is highly valued by the utility.
