By information KP-KTE from 01.11.21. по 30.11.21г. of heating 6053,2m² at home 40b spent 36,816 Gcal coolant, Based on this- should, What's on 1m² flow = 6,082584 Cal. тогда можно определить потребление на отопление квартиры Qтэ/Гкал = Psq / m² x Qte / Kal / m² : 1000. It is also desirable with considering, the existing fraud, embezzlement and corruption the existing on the territory of the state of Ukraine to exercise control by representatives of the house for the testimony of the general counters потребления теплоносителя домом 40б в конце каждого месяца. Place the information of this control in the above form in this table for the knowledge of all consumers at home 40b.

Risers of the house 40b(further-Tc)

Tc = 1k-4k,4White, 5k-11k

only the 4k riser is shown which provides the apartments: 4k4, 4к15, 4к26, 4к37, 4k48, 4к59; 4к70; 4к82?; 4к93? utilities – вентиляцией, cold water, drainage system, hot water, heating, electricity.

. Highlighted area A – for understanding, what are hammered battery apartments and air jams in them do not affect the normal operation of the riser and heating of other apartments.

Normal house heating 40b, это когда начиная от температуры наружного воздуха +10 supply pipe temperature +41 on the return pipeline +36 – at outdoor temperature -22, serving +90, reverse +70, for outdoor temperature from +10 to -22 degrees look by g. Kiev t-graph 70 -22 90. A prerequisite for normal functioning heating, the coolant in the supply and return pipelines, regardless of the floor of the location of the apartment, must be the same. and batteries in all apartments with 10 by 2 all floors, without exception, must have the same temperature, if these conditions are not met, this is regarded as the absence of normal heating of the house.

DBN B.2.5-39:2008 The average annual temperature of return pipelines of water heating networks should be taken 50 ° C.
13.7 When placing heat pipes in service помещениях, technical floor space and basements of residential buildings, the air temperature should be taken 20 ° C, and the temperature on surface of the heat pipe structure – not higher 40 ° C. In this case, thermal insulation structures should be used. из негорючих материалов.

Для нормальной работы систем отопления запрещается производить замену элементов отопления, change the cross-sections of pipelines that differ from the parameters set by the project, такая замена ведет к дисбалансу всей системы отопления дома.

Customization two-pipe heating systems apartment building

Процедура настройки: осуществляется с помощи устройств терма регулировки (hereinafter - UTR), installed in front of the radiators (batteries) installed in apartments, starting from the nearest to the heating point starting from the apartments, located near those. floors, reducing the flow of water through them. The purpose of the adjustment is to do so, so that a decrease in the flow of water through the nearest heating devices will increase the water consumption on the far ones located on the second floor.

Процедура проста при понимании процесса: slightly reducing the water supply using the UTR on the radiators closest to the heating point, добавляем при помощи УТР подачу воды на дальних радиаторах. При этом с помощью термометра проверяем температуру радиатора она должна соответствовать температурному графику, можно это сделать приблизительно при помощи человеческая руки, which feels a difference of five degrees.

Another way, кроме как «подкручивать и мерить», not yet: рассчитать точную проходимость для каждого УТР начиная от +40⁰From to +95⁰С температуры теплоносителя, and then also adjusting it to achieve the required figures is a task that is hardly feasible.

Two moments, which need to be considered, когда осуществляется регулировка двухтрубной системы отопления:

1. It takes a long time because, that after each change in the dynamics of the coolant, the temperature distribution stabilizes for a long time and requires fine-tuning at the heat point after the steady state to the norms of temperature indicators, set by the temperature schedule for outdoor air, теплоносителя в трубопроводах подачи и возврата на всех батареях дома .
2. Heating regulation of a two-pipe system should be carried out before the onset of cold weather. This will prevent the possibility of defrosting the home heating system., в случае не квалифицированной регулировки отопления.

Armature, which is installed when connecting radiators (batteries) apartments

• Shut-off valves, installed in front of the radiators (batteries) - when installing a ball valve, its handle should be in two extreme positions open or closed, if this condition is not met, this crane will quickly fail.
• Plug, to overlap channels;
• Mayevsky crane for air release at the time of seasonal launch;
• Additionally, sealants are used - special compounds or tapes.

Дополнительные устройства для контроля и защиты нормальной работы радиаторов (batteries) apartments:

• Pressure gauge with filter, installed after the crane in front of the UTR and the radiator (batteries) for measuring the pressure in the supply pipe and protecting the radiators (batteries) от засорения и предоставления возможности промывки этого фильтра без его разборки.
• Manual controller or automatic thermostat, allowing to expose the radiator (battery) at a certain temperature.
