Germany - Installation of heating, ventilation and air-conditioning systems

Description

In Hall 13 there will be 9 ventilation systems (LT system 1 "Exhibition hall" (V = 15 300 m3/h); LT system 2 "Office" (V = 7 990 m3/h); LT system 3 "Sanitary areas ground floor" (V = 780 m3/h); LT system 4 "Sanitary areas upper floor" (V = 1 380 m3/h); LT-system 5 "Snack" (V = 2 600 m3/h); LT-system 6 "DRK" (V = 1 050 m3/h); LT-system 7 "Technology 1" (V = 100 m3/h); LT-system 8 "Technology 2" (V = 60 m3/h); LT-system 9 "Technology 3" (V = 250 m3/h); Air ducts & fittings: approx. 2 000 m2; spiral duct: approx. In Hall 13, the exhibition hall (150 kW) as well as the office areas (90 kW) are cooled both via the LT units and via circulating air cooling cassettes (connection to the trade fair's internal 6/12oC refrigeration network); sub-areas such as technology and server rooms (40 kW) are also supplied via split refrigeration systems.RWAD The vestibule area is de-smoked via a mech. smoke extraction system planned on the roof (V=10 000 m3/h). Hall 13Renewal of the heat supply system and connection to the existing HDHW network of Messe Berlin. Heat is transferred from the HDHW network via 4 plate heat exchangers with a total output of approx. 1,200 kW. 2 static and 2 dynamic heating circuits are to be newly installed in the central heating system. Furthermore, an already existing static and 2 dynamic heating circuits are to be connected. 2,000 m of pipeline between DN15 and DN100, approx. 1,500 m of insulation, of which approx. 750 m with sheet metal jacket, approx. 60 radiators and 20 fan convectors are to be assumed. VentilationIn Hall 16 there will be 4 ventilation systems (LT system 1 "Exhibition hall" (V = 19 100 m3/h); LT system 2 "Office" (V = 9 300 m3/h); LT system 3 "Sanitary areas" (V = 1 950 m3/h); LT system 4 "Technology" (V = 150 m3/h); Air ducts & fittings: approx. 1 800 m2; spiral ducting: approx. 300 m, MiWo insulation (diffusion-tight & normal) (aluminium-laminated & sheet metal jacket)ColdIn Hall 16, the exhibition hall (150 kW) is cooled both via the LT units and via circulating air cooling cassettes (connection to internal 6/12oC local cooling network); the office areas (80 kW) are cooled via the ventilation system (connection to cold water network) and via a split system combined with ULK´s; sub-areas such as technology and server rooms (40 kW) are also supplied via split cooling systems.RWAD The vestibule area is de-smoked via a mech. smoke extraction system planned on the roof (V=10 000 m3/h). Renewal of the heat supply system and connection to the existing HDHW network of Messe Berlin. Heat is transferred from the HDHW network via 4 plate heat exchangers with a total output of approx. 1 800 kW. 2 static and 3 dynamic heating circuits are to be newly installed in the central heating system. In addition, 2 existing static and 2 dynamic heating circuits must be connected, approx. 2000 m of pipeline between DN15 and DN125, approx. 1 500 m of insulation, approx. 600 m of which with sheet metal jacket, approx. 50 radiators, 20 fan convectors and 2 air curtain systems must be assumed.
