Work Detail

Heating, Ventilation And Air-Conditioning Installation Work – Heating And Cooling Technology. The Nienburg/Weser District Is Planning To Build A New Fire Service Center (Ftz) In The Commercial Area Of ​​The Town Of Lemke, Municipality Of Marklohe. It Is A Replacement Building For The Existing Ftz On Verdener Landstrasse In Nienburg. The Room Program Includes Approx. 8,200 M² Of Usable Space, As Well As Approx. 9,140 M² Of Outdoor Areas - Exercise And Exercise Areas. A Construction Site Of Approximately 3.4 Hectares Is Available For This Purpose. The Construction Project Involves Individual Building Parts With A Steel Truss Structure With A Trapezoidal Surface. The Advertised Services Include: Heating And Cooling Technology In Accordance With Din 18380. Heat Is Generated Via Two Roof-Mounted Air-Water Heat Pumps, Each With A Heating Output Of Approx. 135 Kw. R290 (Propane) Is Used As The Refrigerant. The System Temperatures Of 40/30°C Are Designed For A Low-Temperature System And To Increase System Efficiency. Heat Is Usually Transferred In The Main Building Via Radiators Or Underfloor Heating. The Basic Heating For The Main Vehicle Hall And The Workshop Halls Is Provided By Industrial Underfloor Heating. Additional Air Heaters Are Provided In The Workshop Halls To Briefly Heat The Halls To 19°C. For Short-Term Heating Of The Main Vehicle Hall, Three Additional 9 Kw Electric Heaters Will Be Installed. The Multifunctional Hall Is Heated Exclusively Via Air Heaters. The Training Rooms On The 1St Floor Are Heated Via A Heating-Cooling Ceiling. The Cold Is Generated Via An Air-Cooled Compression Refrigeration Machine With A Cooling Capacity Of Approx. 58 Kw, Which Is Installed On The Roof. R290 (Propane) Is Used As The Refrigerant. Compressor, It And Ups Rooms As Well As Server Rooms Are Cooled Using Circulating Air Coolers. A Heating-Cooling Ceiling (Supported By Air-Conditioned Supply Air) Will Be Provided For The Training Rooms. The Heat And Cold Are Distributed In A 2-Pipe System With Parallel Flow And Return. Stainless Steel Pipe Is Planned As The Pipe.
