Tenders Are Invited For Heating, Ventilation And Air-Conditioning Installation Work – Bed Block Renovation, Technical Level 3 | Geothermal Energy

Heating, Ventilation And Air-Conditioning Installation Work – Bed Block Renovation, Technical Level 3 | Geothermal Energy. The University Hospital Of Cologne, Represented By Medfacilities Gmbh, Is Planning To Work On The Existing Geothermal Well System On The Site Of The University Hospital Of Cologne At Kerpener Straße 62 In 50937 Cologne. The Measure Serves To Optimize The Controllability Of Volume Flows Within The Geothermal Network In Order To Benefit Directly From The Improved Control Behavior When The Bed Block Is Connected. For This Measure, Dismantling And Conversion Measures Are Necessary, Especially To Adapt The Tga. It Is Intended To Replace The Existing Flat Valves In The Return Lines To The Geothermal Wells (Summer Wells 1+2 And Winter Wells 1+2) With Annular Piston Valves. To Do This, It Is Necessary To Dismantle The Double Flat Slide Valves Dn150 Including The Y-Pipes On The Upstream And Downstream Sides. Fittings Or Reducing Pieces Must Then Be Made From Stainless Steel In Order To Mount The New Annular Piston Valves Between The Existing Flange Connections. In Addition, Additional Pipeline Fittings Will Also Be Installed As Part Of This Measure. The Adapters And Reducers To Be Manufactured Must Be Made Individually For The Respective Installation Location. To Do This, The Contractor Is Responsible For Determining The Necessary Dimensions On Site And Making A Sketch. The Effort Required For This Is Queried In A Separate Item. Three Of The Annular Piston Valves Are Located In The Foreshafts Of The Respective Geothermal Wells, The Fourth Valve Is To Be Installed In One Of The Awt Corridors Under The Ceiling. The Dirt Traps Should Be Installed In The Well Shafts.
