Title: Industrial Heating/Cooling Combination
The project is about the development of a cooling/heating combination facility for supermarkets, industry cooling, storage of food, etc. The facility operates both cooling units and rooms and the entire heating system. The waste heat of the cooling units as well as heat from the soil is used optimally. In winter the waste heat is used for heating. If the waste heat is not enough during cold outdoor temperatures, the missing heat is gained through subterranean depth probes. Alone with this system the whole building can be heated without an additional heat supply. Therefore 70 to 95% of heating costs can be saved. In summer, the waste heat is used for regeneration of the depth probes.
