But it only worsened the rest: the system turned out of balance. Technological disaster was brewing. As a result, last year, the heat supply was stopped and homes were left without heating. In this situation, quarterly boiler construction was unsustainable because of lack of sufficient kolichesstva potrebitley. In this regard, the city administration had approved our proposed plan for building an autonomous source of heat for these homes. Independent source of heat consists of a boiler room and room accessories. Boiler Room, located on the roof of the house 17 (on the technical floor). Boiler room is designed for heating systems and hot water heating residential buildings.
The heating system houses closed, and connected to the independent circuit after two brazed plate heat exchanger. Coolant circuit of an independent heating system – the water with the parameters of 85 – 65 C. Regulation of fluid parameters in an independent circuit of the heating system quality depending on the temperature outdoor air. Hot water temperature in the hot water – 55 C. To account for the generated heat in the auxiliary equipment installed metering of heat energy. To compensate for thermal expansion of water compensator system has the volume capacity of 700 liters.

As the source water of drinking quality water is used. The rigidity of the original water 7 mEq / L, soft water hardness 0.1 meq / liter. To account for the flow of water to recharge the system, installed water gauge site. Boiler room operates in automatic mode without permanent staff, and signaling violations of the work. Periodic monitoring of the equipment carried by the operating organization in the prescribed order. Heating boiler room at the expense of teplopostupleny equipment and pipelines and gas convector LB-30. The internal temperature in the boiler room +5 C. Heating facilities support The equipment is due to teplopostupleny of equipment and pipelines, and 8-sectional cast iron radiators M140-AO. The internal temperature of the room accessories +12 C. . Ventilation of boiler room supply and exhaust of natural type of calculation: drawing – in the amount of three times the air changes per hour; flow – in the amount of extract plus additional amount of air for combustion gas in the heating module. Air flow for ventilation and combustion gas in units of heat through the louver array, located in the outer wall of the boiler room. Hood through ventkanal isolated. Ventilation accessories made of existing systems, general ventilation. Water boiler provided from the reconstructed water-supply input of a house. On entering the water supply system installed water gauge site. Water is used to fuel heating systems and hot water production. To receive a water spills on the floor of the hall and boiler room room accessories provide the ladder with drainage into the existing sewerage network of the building. Automatic fuel cut to the modules takes place at: – increasing or decreasing pressure gas burners in front of – the absence of traction control – too hot water – reducing water flow through the boiler. On entering the pipeline to the heating modules set-off solenoid valve. Automatic fast gas valve closing-off provided for: – fault protection circuits and power failure – the boiler room gas contamination – a fire. In the boiler room set alarm gassed "Lelek." Estimated consumption of gas boiler: in winter – 129.46 m3 / h in summer – 48.4 m3 / h.
