Technical workshop: Low temperature district heating

, , , ,
We arranged a technical workshop to share our experiences and hear other cities thoughts about low temperature district heating.  On March 23, we gathered the municipalities and energy companies from three Swedish cities to talk about low…

Cool District Heating allows a new kind of plastic pipes

, ,
At the Cool DH demonstration site in Brunnshög, Lund a new kind of plastic pipes have been installed successfully. The new PE-RT pipes comes with benefits such as less joints and more customized design. The PolyEthylene Raised Temperature…

Heat-recovery enabled pipes

,
In classic district heating grids, up to 15-20 % of all the energy produced does not reach the customers due to heat losses. This is a weakness with district heating which we are addressing in COOL DH.

Design Guide for Low Temperature District Heating

,
This guide by Cetetherm explains how to design and prepare buildings to be able to integrate low temperature district heating. It will assess the best of hot water and space heating system design for different buildings categories.
The image shows how the installation of the LTDH-service pipes in Osterby are close to the users' buildings in order to reduce the length of the network and consequently the heat losses.

From traditional DH to LTDH in Østerby

, , , ,
A new low-temperature network has been designed to upgrade the old and obsolete traditional district heating-network in Høje-Taastrup. This report provides information about the final design and the implementation of the low-temperature district heating network and can be used as a guideline of the installation process for future similar projects.

Corona, webinars, CPS and new substations: COOL DH newsletter #4

, , , ,
It has been a strange spring. Each person around the globe has felt the effects of the spread Covid-19, but so far it has had a relatively limited impact on the overall progress of the COOL DH-project. There has been some problems with deliveries…

Producing heating, cooling and surplus heating for the LTDH grid

, ,
In COOL DH we develop and demonstrate a range of technologies to supply low-temperature networks with heat without compromising the users' comfort and the efficiency of the district heating system. In Lund, Kraftringen has installed a heat recovery system at MAX IV research facility, supplying the new Brunnshög district with low temperature district heating.

Inspiration: LTDH in the public space

What would be possible if we had close to an unlimited amount of lukewarm water? After conducting workshops, exploring existing ideas and promote low temperature district heating to the public we ended up with some exiting ideas on how to use LTDH in the public space.
COOL DH & Celsius talk

CoolDH & Celsius Talk: Low Temperature District Heating

, ,
This webinar is hosted in partnership between Celsius, a demand driven collaboration hub for efficient, integrated heating and cooling solutions supporting cities in their energy transition to carbon-neutral systems, and COOL DH. Together we will present some of the opportunities and challenges cities may encounter in their endeavour towards a sustainable and efficient energy system.
