Tenders Are Invited For Infrastructure Renovation And Measures To Increase Energy Efficiency, Repair And Delivery Of Equipment And Furnishings Of The Building Of Acad. Daki Yordanov - Omurtag

The Subject Of This Public Procurement Is Infrastructure Renovation And Measures To Increase Energy Efficiency, Repair And Delivery Of Equipment And Furnishings Of The Building Of Acad. Daki Yordanov - Omurtag. When Executing The Order, The Following Works Should Be Carried Out On: Measure 1 Thermal Insulation Of Facade Walls. Thermal Insulation Of Exterior Walls From Thermal Insulation Boards Eps With A Thickness Of 15 Cm With A Heat Transfer Coefficient Of 0.035 W/(M.K). As A Result, The Summary Of The Walls Should Reach U = 0.22 W/M2 K, Which Is Required According To The Oree. Measure 2 Thermal Insulation Roof. For The Thermal Insulation Of The Roof, It Is Envisaged To Apply Mineral Wool With A Thickness Of 15 Cm Λ = 0.04 W/Mk, Applied On An Attic Plate. Measure 3: Construction Of A Heat Pump Installation The Construction Of A New Heating System Is Proposed. As A Result, The Efficiency Of The Delivery, Distribution Network, Control And Efficiency Of The Whole System Will Be Increased. This Installation Will Operate On Electricity, Which In The Largest Part Will Be Delivered By A Photovoltaic Plant Mounted On The Roof Of The Building. Measure 4: Photovoltaic System For Own Consumption. On The Metal Structure Of The Roof Of The Building A Photovoltaic Generator Will Be Installed 30.24Kw With Single Crystal Panels Jkm540m-72Hl4 Consisting Of 10 Strings. To Achieve Optimal Results, The String Are Made Up Of 6 Strings Respectively With 6 Pcs. Consistently Connected Panels And 4 Strings With 5 Pcs. Consistently Connected Panels. The Poles Of The Stream Are Supplied With A Separate Entrance To The Inverter With Dc (Dc) Cable. To Protect The Individual Strings And The Ability To Exclude Individual Strings, They Are Included In The Assembly Box Through Regular Terminals With Built -In Fuses. For Each Dc Dashboard, An Arrestrun Protection Against Atmospheric Surge Will Be Installed. The Links Between The Individual Modules Have Cable Conclusions With Nozzles, An Integral Part Of Each Panel. The Cables Between The Streams And The Collecting Boxes, As Well As Between The Collecting Boxes And Inverters Are Protected From External Influences Multi -Wire Cable With Increased Mechanical Strength, Resistance To Temperature And Ultraviolet Rays Specialized For High Constant Voltage. The Cables Are Laid On Metal Grills Attached To The Supporting Metal Structure. To Reduce Overall Inductance And Increase Protection Against External Inductive Voltages (As Occur When Lightning Or Lightning), The Total Area Of ​​The Current Contours Of The Individual Strings Is Minimized, With The Plus Conclusion As Close As Possible To The Minus Conclusion. This Achieves Maximum Protection And Minimum Voltage Pulse Height In Case Of Overvoltage. Esm 5 - Measure By Lighting System. Important! A Detailed Description Of All The Intended Activities And Their Volume Is Contained In The Technical Specification And Investment Project Attached To This Documentation - Annexes 1 And 3.
