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.
The aim of the project is to develop, optimise and construct a resorption chiller for decentralised cooling and ice generation. The use of an ammonia-water absorption mixture enables low-temperature sources to be efficiently used in the 70-90 °C range. The use of ice storage devices also enables delayed cooling as required.

Micro-CHP systems are highly efficient plants that can supply buildings with electricity and heat. Optimising the method of operation can improve the economic efficiency. It is planned to use these systems in future as components in smart grids.

In this project two engine concepts are being investigated. The first concept is based on opposed piston technology. The prototype displays several innovative structural features that are expected to increase the efficiency compared with similar engines. The second concept is based on scotch yoke crank technology, whereby the crank drive is separated from the cylinders. This helps to prevent oil ageing when using corrosive gases.
