Tenders Are Invited For Building Construction Work- Renovation Of The Triple Gymnastics And Sports Hall On Budrio Allee 2 In 82223 Eichenau

Building Construction Work- Renovation Of The Triple Gymnastics And Sports Hall On Budrio Allee 2 In 82223 Eichenau. The Following Services Of The Kg 420 (Heating Technology Systems) Must Be Provided: The Existing Building Is Currently Supplied With Heat Via A Combined Heat And Power Plant (Chp) And A Gas Boiler. The Existing Chp Has Reached The End Of Its Lifespan And Is Replaced By An Air Heat Pump For External Installation. The Gas Kettle Remains For The Top Load Cover. According To Construction Physics, The Renewable Proportion Of Heat Supply Must Be> 65% In The Future. The Required Power Of The Heat Pump Is Therefore 90 Kw In The Standard Design Point. The Heating Load Including A New Intermediate Was Calculated In Accordance With Din En 12831 And Is 96.8 Kw.Der Existing Heat Buffer Storage With A Volume Of 3M³ Remains And Is Also Sufficiently Large For Future Heat Generation With Heat Pump. The Pressure Posture Is Due To Change Of The Plant Volume Renewed. In Addition, We Intended To Have A Vacuum Gas, Which Can Also Be Used For The Cold Network (Heating / Cooling Switching Mode). Another Underfloor Heating Distributor Is Positioned In The Basement For The Barrier -Free Toilet. In The Gymnasium, The Entire Sports Soil Heating Including Distributors And Connecting Lines Is Renewed. The Two Ventilation Devices Of The Sports Hall Are Equipped With A Change-Over Register And Provided With Heat Or Cold. The Heat Supply In The Intermediate Building Is Implemented Via Underfloor Heating. At This Point, The Surface Heating Is Designed For Temperatures Of 35/28 ° C (Lead / Return). The Heat Supply In The Sports Hall Is Realized Via A Sports Soil Heating. This Is Designed For Temperatures Of 55/47 ° C (Lead / Return). The Heat Pump Is Carried Out Reversibly And Thus Also Used To Cool The Sports Hall. The Intended System Parts (Sports Soil Heating And Ventilation Devices Sports Hall) Are Used To Achieve Partial Cooling. The Same Lines Are Used To Connect The Sports Soil Heating And The Ventilation Devices As For Heating Mode (Central Switchover). The Lines Are Insulated Due To The Double Use With Cooling Mode.
