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

About Cool DH

Cool DH explained in 4 minutes

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.

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.

Prototype for new multimedia pipe types for LTDH distribution system

This deliverable investigates the possibility of implementing a heat recovery system in the distribution pipes of a district heating network. The aim with the multimedia pipes is to minimise the heat losses from the distribution pipes.

Draft design manual for new pipe components for LTDH distribution systems underground

,
The implementation of LTDH network and the development of the DH pipes production allow the use of in flexible plastic pipes also for main lines. This deliverable provides the draft of the installation manual of the new pipe components for LTDH distribution systems in Høje-Taastrup and Lund.

Calculator on savings for new high-efficient pipe types for internal distribution in buildings

, ,
This deliverable presents the calculation tool and guidelines for calculating the heat loss from the distribution pipes in buildings.
