Increased trench soil temperatures from district heating operation can lead to heat gains in district cooling pipes.
Experimental temperature measurements and finite element modeling were applied to a 175-meter section of Munich's network.
Heat transfer simulations confirmed that without district heating, ground and district cooling temperatures align, preventing heat gains.
The validated model is essential for assessing heat dynamics in future urban infrastructure designs.
