The Polyvalent Heat Pump Is The Main Source Of Heating And Cooling For The Building. The Monoblock Refrigeration Machine And The District Heating Are Used To Cover Peak Loads And To Ensure Redundancy In Energy Production. The Central Distribution For Heating And Cooling Is In The Middle Wing. The New Control Center Building, The Middle Wing And The Office Wing Are Supplied From There. The Control Center Area Is Supplied By Circulating Air Cooling Units As Well As Heating And Cooling Ceilings. While The Circulating Air Cooling Units Provide The Required Cooling Capacity For The Control Center Operation, The Heating And Cooling Ceilings Are Used To Control The Basic Temperature Of The Rooms. Radiators Are Also Installed In The Stairwell. The Office Wing Is Supplied With Underfloor Heating. The Cold Distribution In The Office Wing Will Be Renewed As Part Of The Construction Project And Then Connected To The Central Cooling Supply. The Heating And Cooling Piping Is Made Of Steel. Insulation And Fire Protection Of The Systems Are Part Of This Award Unit. The Heating Pipes Are Predominantly Insulated With Mineral Wool, The Cooling Pipes With Elastomer Foam. There Are Interfaces When Connecting The Series Cooling Devices. The Connecting Cables To The Devices Are Manufactured By The Contractor Hzg/Klt. The Building Automation Takes Over The System And Room Control As Well As The Interconnection Of The Generation Components. High-Performance Customers Receive The Power Connection From The Elt Trade, While The Electrical Connections Are Connected By The Contractor Hzg/Klt.
