Germany - Installation of heating, ventilation and air conditioning systems

Description

Heat supply systems consisting of 2 brine/water heat pumps with a total output of 160 kW with optional cooling; geothermal probes with 66 brine circuit pipes made of pressed copper and welded steel; 81 radiators and 1 973 m2 active ceiling heating and 1 045 m2 passive and 670 m2 floor heating with plastic pipes; the system is built as a low temperature system with temperatures V= 35oC and R= 30oC, on which the ceiling radiant panels and all radiators are to be designed. The building can be passively cooled via the earth probe field and, if additional cooling is required, it can also be actively cooled. The passive cooling is to be used primarily to reactivate the ground, and construction will take place in the period: Lot 1 Extension of Wing N from August 2021 to September 2022 Lot 2 Renovation of Wing I and VIIIAug
Heat supply systems consisting of 2 brine/water heat pumps with a total output of 160 kW with optional cooling; geothermal probes with 66 brine circuits with 6600 m length and 27 m3/h total volume flow.The system is built as a low temperature system with temperatures V= 35oC and R= 30oC, on which the ceiling radiant panels and all radiators are to be laid out. The school is seen as a pilot project as we supply the whole building with renewable energy. The building can be passively cooled via the earth probe field and, if additional cooling is required, it can also be actively cooled. The passive cooling is to be used primarily to reactivate the soil, and the construction process will be carried out in the period: Lot 1 Extension of wing N from August 2021 to September 2022 Lot 2 Renovation of wing I and VIIIAugust 2023 to September 2024
