Energy Centre of the University of Bremen: Conversion/renewal of the refrigeration system - technical equipment, project planning Buildings Text automatically translated in your browsing language Automatically translated

The energy centre of the University of Bremen provides a central supply of cold water. The University of Bremen intends to renew the refrigeration system. In the course of this measure, both the roof of the energy center must be renovated. For this purpose, various variants with regard to their sustainability and economic efficiency are to be examined. Possible subsidies are to be shown according to the variants. The Refrigerant Ordinance must be observed in order to meet the increasing requirements in the future. It should be noted that the old absorption chillers are operated at a high temperature level, supply temperature 125-130°C, return temperature 100°C. The energy supplier (SWB) aims for temperatures of supply 120°C / return 50°C. In addition, a constant supply of refrigeration is essential to maintain the ability to work, especially in the laboratories. The cold water network must continue to be operated with supply 6°C and return 15°C at 7 bar. In accordance with the requirements, economical and environmentally friendly refrigeration with a redundancy and thus low risk of failure will also be required in the future. A concept has to be developed in order to be able to cover base and peak loads sensibly. The refrigeration supply must be converted during operation. After an initial assumption of costs, the construction costs (KG 300 + 400) amount to: - KG 400: approx. EUR 13.6 million net (ALG 3: approximately EUR 13.2 million; ALG 4: approx. EUR 0,1 million, ALG 8: approximately EUR 0,3 million); - KG 300: approx. EUR 1.1 million net. Text automatically translated in your browsing language Automatically translated
