Efficient reuse of waste heat from all system elements

The utilisation of waste heat from upstream processes through downstream heat recovery (WRG) offers exceptionally high energy saving potential. This makes economic and ecological sense. It is already integrated into the return flow utilisation system from Baunach. The system, which is being planned and implemented at Menshen by master craftsman and engineer Jakob Appelhans and his team from Sorpetaler Energie using hydraulic concepts and products from HG Baunach GmbH & Co. KG, links numerous waste heat producers and consumers as well as countless technically optimised individual elements. Heat is recovered here at every turn, e.g. from the compressed air compressors in the production area, the thermostats in the office area, and countless other sources. consumers as well as countless technically optimised individual elements. Heat is recovered here at every turn, e.g. from the compressed air compressors in production, the thermostatically balanced condensing boilers and through return flow utilisation. It is used, for example, in the radiator circuit for frost protection in the It is used, for example, in the radiator circuit for frost protection in the energy supply centre and in several buffer storage tanks. Special valve technology ensures constant temperature-controlled hydraulic balancing of the heat generator and heat consumer circuits, while the buffer storage tanks use the so-called two-zone principle.

“This shows how a building can be advanced in terms of climate protection and that significant energy savings can still be achieved without incurring huge financial costs,” praises Prof. Dr Bert Oschatz from the Institute for Technical Building Equipment in Dresden in his laudatory speech.
