Kujawska 22, 88-153 Kruszwica.Iii. Scope Of Construction Works: The Basis For Carrying Out The Task Of Reconstruction/Modernization Of The Existing Heat Distribution Center Is The Developed Executive Construction Design For The Reconstruction/Modernization Of The Existing Heat Distribution Center In The Building Of The Local Government School Complex No. 1 In Kruszwica At Ul. Kujawska 22. The Following Assumptions Were Made In The Preparation Of The Cost Estimate. The Installation Technology With Parameters Of 100/65 Degrees Celsius From The Municipal Heating Network Together With The Existing Jad 6/50 Type Exchangers For The Central Heating Installation And Jad 6/27 Type For The Preparation Of Domestic Hot Water Remains Without Changes. Below Is A General Description Of The Designed Works To Be Performed As Part Of The Reconstruction/Modernization Of The Existing Node: In The Installation Technology System With Parameters 100/65 Degrees Celsius, It Is Planned To Install Control Valves For Central Heating And Hot Water Exchangers And A Differential Pressure Regulator. In The Central System Heating With A Parameter Of 80/60 Degrees Celsius, The Following Works And Elements Are Planned: - Replacement Of Pipelines Necessary For The Planned Changes - Replacement Of The Closed Expansion Vessel Type N5 - Liquidation Of Existing Circulation Pumps - Construction Of New Pump Mixing Systems Using New Circulation Pumps For Individual Circuits Central Heating And Ventilation On Power Cables Coming From The Power Distributor And Three-Way Valves With 230V Actuators; Circulation Pumps And Three-Way Valves With Automatic Regulation By Ecl 310 Type Regulators With The Central Heating Application Key A390. - Installation Of New Fittings And Akpia Equipment Necessary For The New Solution - Anti-Corrosion Coating On The Pipelines And Thermal Insulation Made Of Pur Polyurethane Laggings. - New Measurement Is Planned Heat Consumption For The Purpose Of Preparing Domestic Hot Water, Which Will Act As A Submeter. All Installation Regulators, Pumps And Control Valves Will Work In The Machine, Cooperating With The Installed Immersion Or Contact Sensors And An External Weather Sensor. The Domestic Hot Water Preparation System, Due To Its Failure Rate , On The Domestic Water Side, Is Intended To Be Replaced In Its Entirety, Together With The Existing Storage Heater. The Domestic Hot Water Preparation System Includes An Additional Water Meter That Serves As A Submeter Indicating The Amount Of Water Used For Dom
