Tenders Are Invited For Ventilation Installation Work - Ludwigslust-Parchim District - Extension For The High School School Center In 19243 Wittenburg - Lot 43 - Ventilation And Building Automation

Ventilation Installation Work - Ludwigslust-Parchim District - Extension For The High School School Center In 19243 Wittenburg - Lot 43 - Ventilation And Building Automation. Lot 43 Includes All Ventilation And Building Automation Work (Msr) In The New Extension Building And In The Foyer Area Of ​​The High School Center. The Services Must Be Implemented In Accordance With The Implementation Planning, Din Standards As Well As Applicable Technical Rules And The Specifications Of The Tga Planning. The Work Will Be Carried Out In Several Staggered Construction Phases. Description Of Services - Mechanical Ventilation Systems Mechanical Ventilation Is Provided To Maintain The Permissible Co Concentration Of A Maximum Of 1,000 Ppm. The Technical Solution Must Be Taken Into Account In Connection With The Requirements Of The Building Energy Act (Geg). The Following Areas Are Ventilated Via Central Ventilation Systems: System 1 System 1 Supplies All Internal Areas, The Classrooms And The Vestibules. - Air Volume For Continuous Operation: Approx. 4,500 M3/H - Total Air Rate Of The System: 19,000 M3/H - Duct Masses Of Supply And Exhaust Air: 782 Pieces. Duct Component; 594 Pieces Of Fittings; 79 St Transitions In Addition, The System Supplies Variable, Usage-Dependent Areas: Variable Exit - Cafeteria/Market Square - Air Volume: 3,000 M3/H - Operation Depending On Time Control Variable Exit - Classrooms (New Building, 17 Units) - Air Volume Per Classroom: 900 M3/H - Total Air Volume For 17 Rooms: 15,300 M3/H - Operation Dependent On Usage And Air Quality - Control Depending Room Above Co Sensor (Wall-Mounted) Exhaust Air Systems - Natural Science Room Chemistry - A Separate Exhaust System With 500 M3/H Must Be Provided For The Extraction Of Hazardous Substances. - The Exhaust Air Is Ducted Independently Of The Central System 1 And Must Be Designed In Accordance With The Requirements For Safety-Relevant Laboratory Exhaust Air Systems. - The Hazardous Substances Cabinets Are Ventilated In Continuous Operation Via An Independent Exhaust System. Simultaneity The Total Ventilation Volume Of All Sub-Areas Exceeds The Rated Output Of The Ventilation Device. A Simultaneity Factor Was Therefore Taken Into Account During The Design. The System Is Dimensioned So That Not All Areas Are Operated With Maximum Air Volume At The Same Time. The Control Is Based On Demand Via Co Sensors And The Usage Requirements Of The Individual Rooms. This Ensures Energy-Efficient And Geg-Compliant Operation Without Affecting The Air Quality In The Areas Used. Appendix 2 A Separate Supply And Exhaust Air System Is Provided For The Serving Kitchen. - Total Air Rate: Approx. 2,650 M3/H (Assumption Due To Lack Of Kitchen Planning, Empirical Values) - According To Lüar, Grease-Contaminated Ducts Are Routed Separately In The L-90 Version Over The Roof To The Ventilation Unit - Duct Masses For Supply Air: 25 Duct Components; 81 Pieces Of Fittings; 1 Piece Of Transitions - Duct Masses For Exhaust Air: 13 Pieces Of Duct Component; 49 Pieces Of Fittings; 3 Pcs. Transitions Installation Of The Ventilation Devices - Ventilation Devices Are Installed On The Roof - Access Via One Of The Necessary Stairwells Is Provided For Maintenance Purposes. Total Air Volume Overview - System 1 Total: 19,000 M3/H - Continuous Operation
