Work Detail

Ventilation Installation Work – New Construction Of A Climate-Neutral Administration Building - Ventilation. An Air Conditioning Unit Will Be Provided In The Basement Of The Building. The Ventilation Was Set To The Requirements Of Cat. 2 (2X Room Air Change With Fresh Outside Air) And Cat. 3 (1.5X Room Air Change With Fresh Outside Air). According To The Assessments Of The Building Physics, There Are Requirements To Equip The East/West Facade, Rear Part Of The Building, With Night Ventilation With Double Air Exchange. The Certification Requires At Least 33 M³air/Ap. This Means That The Air Exchange Rate Complements Itself Accordingly. The Ventilation System Can Also Provide Automatic Night Ventilation Without Users Having To Leave The Windows Open. This Night Ventilation Provides The Building With Fresh, Cooler Air (Depending On Weather Conditions). All Ventilation Systems Follow The Recommendations Of Vdi 6022 Air Hygiene. Ddin Order To Be Able To Adjust The Air Volume To Requirements, Rooms With A Higher Number Of Staff (Meetings, Conferences And Large Rooms) Are Provided With Presence Detectors And Co2 Sensors. The Co2 Sensors Regulate The Amount Of Air Via Flaps On The Floors With Pressure Regulators. As A Result, The Delivery Volume And Operating Costs Are Reduced. The Data From The Technical Systems, Devices, Fire Dampers, Volume Flow Controllers, Co2 Sensors And Presence Detectors Are Summarized Via The Building Automation And Can Be Used For Prioritization. There Is An Adjustment Option For Facility Management Via The Bms User Interface. From The Above Description, A Calculated Air Volume Of Around 12,000 M³/H Results. - 1 Ventilation Unit With 12,000 M³/H - 3 Indoor Units With Cold/Heat Pump Function - 141 M² Air Ducts Made Of Galvanized Sheet Steel With An Edge Length Of Up To 2000 M - 132 M² Rectangular Duct As A Fitting Made Of Galvanized Sheet Steel - 1 Outside Air Tower - 120 Pieces Of Slot Diffuser For Wall Installation Incl. Silencer - 10 Pcs. Volume Flow Controller Variable 300/250 - 115 Pcs. Constant Volume Flow Controller Round 125 - 19 Pcs. Fire Damper 400X300 - 20 Pcs. Louvered Damper With Motor As A Butterfly Valve Dn125
