DHW loop performance control in substations
As part of the delivery of an eco-neighborhood, our customer called on TEC’s teams to assist with the delivery of equipment to maintain the temperature of the DHW loop.
The equipment, located in 10 substations in the basement of the eco-neighborhood, comprises storage tanks, plate heat exchangers and an innovative solution consisting of digital boilers to maintain the DHW temperature.
“Renewable energies
The district is also at the cutting edge of energy innovation. For example, 73% of its energy needs come from renewable sources. This is thanks in particular to its geothermal network, which heats and cools buildings according to the season, and its 4,000 square meters of solar panels on office roofs. According to the developer, this eco-neighborhood emits 36% less CO2 than another type of neighborhood of the same size.” . Les Echos, October 20, 2022.
To verify the power required to maintain the temperature of the DHW loop, TEC’s teams took DHW flow and return temperature measurements at key times, and combined these with ultrasonic flow measurements to determine the power required for each substation. Thanks to TEC’s calculations, our customer was able to optimize its equipment to maintain the DHW temperature for the entire eco-neighborhood.
