Tenders Are Invited For Heating, Ventilation And Air-Conditioning Installation Work – Siebentäler Therme Heiz

Heating, Ventilation And Air-Conditioning Installation Work – Siebentäler Therme Heiz. The Heat Supply System Of The Siebentäler Therme Consists Of Two Combined Heat And Power Plants (Chp) As Well As A Condensing Boiler And A Low-Temperature Gas Boiler. The Heat Generation From 2011 Will Be Retained. In Order To Meet The Fire Protection Requirements For A Boiler Room, The Installation Area For The Boilers And Chps Is Separated With Brick Walls. All Heat Generators (Chp And Fw) Are Connected To A Common Manifold, And The Two Buffer Tanks Are Also Integrated Into This Manifold. The Manifold Feeds The Existing Heating Distributor As Well As A New Sub-Distributor For Building Heating And Air Conditioning Devices And A New Sub-Distributor For The Existing Heating Groups. All Heating Groups Receive Control Valves With Actuators And Flow Temperature Sensors. Underfloor Heating And Heat Bench Groups Are Additionally Protected Via Safety Temperature Limiters And Installed As A Fixed Value Control Set. All Groups Are Controlled According To The Weather Depending On The Outside Temperature, With The Exception Of The Heat Benches, Which Are Operated Constantly. The Heating Cables Are Made Of Black Steel Pipe, The Dimensions Dn 15 To Dn 32 Are Made Of Threaded Pipe, The Rest Are Made Of Seamless Steel Pipe. All Heating Cables In The Basement Receive A Double Coat Of Corrosion Protection Before The Thermal Insulation Is Installed. The Pipeline Network Is Designed For Flow Velocities Of 0.3 - 0.5 M/S In The Small Dimensions And Up To 1.2 M/S In The Larger Dimensions. The Intended Flow Resistance Is On Average 50 - 75 Pa/M And Is Optimized For Low Electrical Operating Consumption. Component 1A: Entrance Area, Administration, Bathing Hall Changing Room, Sauna Changing Room, Technical Areas Partly, Outdoor Pool, Roof Areas Bathing Hall / Changing Room / Entrance The Heat Distribution For These Areas Will Be Completely Renewed. Component 1B: Sauna, Restaurant And Kitchen, Terrace Restaurant, Roof Terrace Upper Floor, Outdoor Sauna Garden The Heat Distribution For These Areas Will Be Completely Renewed. I Space Heating Surfaces The Largest Part Of The Entire Building Is Heated Via The Air Conditioning Systems. However, Individual Zones And Adjoining Rooms Receive Static Heating Surfaces As Well As Underfloor Heating Surfaces With Radiant Heat To Temporarily Switch Off The Ventilation Systems And Save Energy For A Better Quality Of Stay And Comfort. For Heating Surfaces, The Following Designs Were Sampled With The Client: - Horizontal And Vertical Heating Walls (Public Areas) - Convectors (Entrance Hall) - Compact Radiators (Staff Areas) - Underfloor Convectors For Glass Facades (Restaurant, Sauna) The Underfloor Convectors Are Controlled Via A Room Temperature Control. The Remaining Radiators Are Advertised With An Integrated Valve Combination. The Control Is Carried Out Using Thermostatic Valves.
