New design concepts for optimisation of LTDH distribution systems

, , , , ,
In this report you will learn about the design process of a low-temperature district heating network, highlighting the design factors that lead to reduction of heat losses in the distribution pipes. To demonstrate the technology, two real-scale demonstration projects are described in Høje-Taastrup, Denmark and in Lund, Sweden. Emanuele Zilio, engineer at COWI A/S, gave a short interview to summarize the report

Solutions for local integration of renewable energy sources (RES)

, ,
This deliverable summarizes and gives an overview of existing and newly developed technical solutions used for the domestic hot water production that can be implemented in low temperature or ultra-low temperature district heating networks, and that can increase the share of renewable energy in the building sector.

Invitation to external partners to be part of a test bed for Low Temperature District Heating

LTDH connected appliances – eliminating electricity topping of temperature

, , ,
Kraftringen and COWI A/S have produced this report that shortly describes the technology and history of HWC (Heating Water Circuit) appliances, as well as traditional dishwashers that are connected to hot tap water and washing machines with both hot and cold water connections.

How to optimize cascade couplings for best use of low temperature sources

Kraftringen and COWI A/S have worked together on a paper that describes the analysis of energy efficiency in heat pump systems that recover waste heat from low temperature heat sources for District Heating. Martin Gierow, chemical engineer and…
