The goal of the project is to bring experience, knowledge and solutions for the 4 th

Generation District Heating systems to a level where they are ready to be implemented

widely.

• Phase I: document experiences in mature DH countries with very low temperature

systems serving highly energy-efficient new-build developments

• Phase II: analyze and extend the scope of lessons arising from early examples of low-

temperature systems, in order to improve the cost-effectiveness and environmental

benefits, effectively formulating a blueprint for a new generation of district heating.

High Grade Resources

• Have reliably high temperatures that always exceed the DES supply temperature, and

can be used directly whenever it is available.

Low Grade Resources

• Have lower temperatures that are sometimes or always insufficient relative to the

DES supply temperature but always sufficient relative to the DES return temperature.

• If the temperature of the source falls below the DES supply temperature, the

temperature must be polished with other energy sources.

Below Grade Resources

• Always have temperatures lower than the return temperature in the DES, and must be

upgraded with a heat pump.

Renewable Energy & Waste Heat (REWH)

INTERNATIONAL ENERGY AGENCY

District Heating and Cooling, including the integration of CHP8

• At what temperature is the

Renewable Energy or

Waste Heat (REWH)

available, and how does it

compare with the supply

and return temperatures

of the DES?

temperatures (at left), with

• Tools for obtaining actual technical status of pre-

insulated bonded pipes in operation

• A model for decision making regarding actions to be

taken based on– Technical status– Forecasted operational parameters– Requirements on robustness & redundancy– Costs for energy loss, maintenance &

reconstruction

• Predicted degradation & remaining technical life based

on– Accelerated aged pipes– Pipes from field operation– Synthesis of available studies

Objectives of project

District Heating and Cooling, including the integration of CHP

• The accelerated ageing of pipes with both a

standard and a thinner casing is continuing.

• The pipes are exposed to an ambient temperature

of 70°C. The service pipes are kept at four levels:

70°C, 130°C, 140°C and 150°C

• Hence, accelerated ageing cause both deterioration

of PUR at service pipe and deterioration of

polyethylene casing.
