Efficient heat utilisation through new technologies
Thermally-driven micro cooling systems, latent heat and cold storage facilities, ORC technologies or thermally-driven heat pumps: The use of modern building technology and the development of distribution technology and system components represent important aspects of the EnEff:Wärme research initiative - just like intelligent control and measuring technologies. Together, they form a fundamentally new heat supply concept.
In view of the increasingly decentralised energy supply in Germany, the research project at the Technische Universität of Dresden is investigating the interplay between cogeneration systems and electrical loads in buildings both under diverse operating conditions and in regards to overarching control and optimisation strategies.

As part of a nationwide field test, approx. 15 absorption cooling systems with a total capacity of 1.25 MW were installed for a wide range of applications and tested in operation. These systems are based on absorption chillers with nominal cooling capacities of 50 kW (Biene – bee) or 160 kW (Hummel – bumblebee), which were developed in a forerunner project as functional prototypes.

The project makes an important contribution to energy optimisation of district heating networks. With the development of a laser-optical procedure for on-site calibration of large-scale flow meters, they can be calibrated while the network is operational, reducing balancing uncertainties.

The aim of the project is to make use of co-generation heat from particularly effective large-scale plants in areas where heat was previously generated in less effective and particularly expensive units. In addition, it is also intended to reduce the construction costs for district heating transport pipelines through planning, structural and constructional further developments.
