Maqolada suvli bak issiqlik akkumulyatorini balans tenglamasi asosida harorat rejimining (zaryadka va razryadka) matematik modeli ishlab chiqilgan. Matematik modelni ishlab chiqishda suvli bak akkumulyatorining turli hajmlari (40,60,80 va 120 m3) va turli suv sarflarini (2,4,10 va 15 m3/soat) hisobga olgan xolda harorat rejimining natijalari keltirilgan. Balans tenglamasini tuzishda quyosh energiyasi va biogaz qozon qurilmasidan keltirilgan issiqlik energiyalari hisobga olingan hamda suvli bak akkumulyatorining issiqlik saqlash samaradorligi hisoblangan.

The article develops a mathematical model of the temperature regime (charging and discharging) of a water tank heat accumulator on the basis of the balance equation. In developing the mathematical model, the results of the temperature regime are presented taking into account different volumes of the water tank accumulator (40, 60, 80 and 120 m3) and different water flow rates (2, 4, 10 and 15 m3/hour). In compiling the balance equation, the solar energy and the heat energy supplied from the biogas boiler unit were taken into account, and the heat storage efficiency of the water tank accumulator was calculated.

В данной статье разработан математический модель температурного режима на основе балансовых уравнений водяного бака. При разработке математической модели учитывая различные значение объема водяного бака (40,60,80 и 120 м3) и различные значение расхода воды (2,4,10 и 15 м3/ч) приведены результаты температурных режимов. При составлении балансовых уравнений, учитывался солнечная энергия и тепловая энергия биогазовой котельной установки, а также, произведен расчет теплосберегающей производительности аккумулятора водяного бака.
