COOL DH - a pioneering project for district heating solutions #cool_dh

About Cool DH

The objective of COOL DH action is to support cities in their endeavor to plan and deploy new, efficient district heating and cooling (DHC) systems and extend, refurbish existing ones to higher standards. Thus allowing greater uptake of renewables, recovering of excess heat or cold while improving the overall efficiency of the systems.

Demo sites

Brunnshög, Lund

The Brunnshög district is an ambitious project, with the goal to offer the best research and innovation environment in the world and to showcase sustainable urban development. Fully developed the district will have 40,000 inhabitants and employees before 2050. Low-grade surplus heat recovered from the research facilities of ESS and MAX IV will heat the entire district.

Østerby, Høje Taastrup

In 2015, the district heating supply consisted of 51 % fossil free energy from biomasses, the renewable part of waste, solar, geothermal energy etcetera. Using a larger share of low-grade surplus heat and increasing system efficiency is an important step of reducing emissions even more.

Connection of Prosumers in Høje Taastrup

,
The transition to low-temperature supply in district heating networks as well as the transition towards renewable heat sources require new technical solutions that allow the introduction of new actors in the district heating sector. These new actors are defined as prosumers that are both connected to the district heating network as consumers and can deliver heat to the network. In Høje-Taastrup Municipality, different prosumers are already connected or in the process to be connected to the district heating and cooling network.

PV powered cascade heat pump installed in the Østerby district

, ,
In Høje-Taastrup municipality a new heat pump system at the shopping mall CITY2 has been installed. The system supplies the new low-temperature district heating network in Østerby district demo case, including business and nearby hotels, recovering the waste heat from the cooling system.
