Tenders Are Invited For Heating, Ventilation And Air-Conditioning Installation Work – Heating And Refrigeration Systems

Heating, Ventilation And Air-Conditioning Installation Work – Heating And Refrigeration Systems. The Demonstration Center For Sector Coupling Will Be Designed As A Research Building That Combines Laboratory And Office Space. The Building Plot Is Part Of The Research Campus At Schleusengraben. In Terms Of Building Law, The B-Plan Bergedorf 104 / Curslack 19 Is Binding. The 3-Story Building Will Be Arranged At The Gable End Between The Street Am Schleusengraben And The Schleusengraben On The Southern Property Boundary. The Parking Spaces Are Located In The Northern Area Of ​​The Property. The Heating And Cooling Systems Include Heat And Cold Generation, Heat And Cold Distribution As Well As The Space Heating And Cooling Areas For The Demonstration Center For Sector Coupling. The Heating And Cooling Is Supplied Via Three Reversible Air-Water Heat Pumps (Chillers) Installed On The Roof With A Heating Output Of Approx. 30 Kw Or A Cooling Output Of Approx. 45 Kw Per Device, Supplemented By Buffer Storage, An Electric Heater To Cover Peak Loads And A Hydraulically Balanced Pipe Distribution Network Made Of Copper And Steel. Room Conditioning Takes Place Via Radiant Ceiling Panels, Underfloor Heating And Circulating Air Coolers/Heaters (2 And 4-Pipe Devices). ________________________________________________________________________________________ Essential Work: 3 Pieces Of Reversible Air-Water Heat Pumps/Chillers (Heating Approx. 30 Kw / Cooling Approx. 45 Kw Per Device, Roof Installation)// 3 Pieces Of Buffer Storage 1,000 / 2,000 / 4,000 L Incl.
