Mr. Roztashuvannya proyektuyuchoї systami - Mr. Zhytomyr; 2. gerelo heat plant - virobic opaluvalna boiler house; 3. palivo - natural gas; 4. jerelo waterstop kotelnoї - a system of state-drinking water supply, water vlashtovuє all vimogi pitnoї vody, carbonate hardness Lcd = 4.5 mg-eq/l; 5. characteristic of the heat-set system: - a type of heat transfer - water overheating; - a type of heat-set system - zakrita, chotiritrubna and dicotrubna. Chotiri pipelines laid along the main magistrali to ABK (two pipes for opalennya i ventilyatsії, and two pipes for GVP), up to our life - two pipelines (supplied by the first turn of the life of the coolant to the opalenny and ventilation) ; - temperature merezhno ї Vod in podavalny truboprovod_ τ1о = 130 ºC; - temperature merezhno ї Vod at zvorotny truboprovod_ τ2о = 70 ºC; - temperature merezhno ї Vod in podavalny truboprovod_ before a m_stseva a system teplopostachannya τ3о = 90 ºC; - water temperature from the main water pipeline tc = 5 ° C; - temperature garyachoї water at consumption of hot water residue th = 60 ° C; - roserachunkov temperature of ringing rub proyektnoї system of tzp = - 22 ° C; - roserachunkova temperature of the ringing plant proyektnoї system ventilyatsії tzp = - 9 ° C; - trivalism of the disgraced season, - 182 dib.
