Description

The subject of the tender is the heat supply systems consisting of heat generation, heat distribution and space heating surfaces as well as the refrigeration systems for the supply of buildings from district cooling and cold water from groundwater use including cold distribution networks. Heat generation: Groundwater heat pumps (2x70 kW) for base load coverage with two wells in pendulum operation. Installation in technical center, ATEX version due to refrigerant R290. Peak load coverage via district heating connection (2x170kW) Heat distribution: Three distribution networks for static heating, AHUs and post-heaters. Pressureless manifolds as layered accumulators with redundant pumps (n+1) Supply temperature: 50°C (peak load case max. 65°C) Space heating surfaces: Radiators for offices, laboratories, stairwells and changing rooms Cold: Connection to the district cooling network of the RU with separation via plate heat exchangers, air conditioning systems (CHF 8°C, 355 kW), high-temperature cooling (CHF 14°C, 62 kW) with groundwater use, post-cooling via heat exchangers with insufficient groundwater capacity, recovery of waste heat via heat pump for heating support Groundwater use: Heat exchangers for grid separation, water and heat quantity balancing Pendulum operation of wells for heating and cooling purposes (max. ΔT = 5 K) Heating operation: 5.6 l/s (20m3/h), cooling mode: 3.1 l/s (11m3/h) Cold distribution: Four distribution networks with redundant pumps for HVAC systems directly and via pressureless distributor as layer storage with redundant pumps for process cooling, recirculating air coolers and clean room cooling as closed systems.
