Abstract
Холодильная система содержит компрессор для сжатия холодильного агента, конденсатор для конденсации холодильного агента в жидкость, испаритель для испарения жидкого холодильного агента из конденсатора в пар, внутренний контур управления для оптимизации подачи жидкого холодильного агента в испаритель и внешний контур управления для оптимизации уровня холодильного агента в испарителе, при этом внешний контур управления определяет скорость подачи для внутреннего контура управления на основании оптимизации, включающей измерение производительности испарителя, а внутренний контур управления оптимизирует подачу жидкого холодильного агента на основании заданной скорости подачи. Независимые переменные, такие как пропорция масла в холодильном агенте, количество холодильного агента, загрязняющие вещества, неконденсирующиеся вещества, накипь и другие осадки на теплопередающих поверхностях, могут быть оценены или измерены. Модель системы и/или термодинамическую модель, аппроксимирующую систему, например, полученную на основании температуры и давления, измеренных датчиками, а также вычислений или измерений мощности, используют для определения или оценки влияния отклонения от оптимального состояния на коэффициент полезного действия. Различные способы предложены для возврата системы в оптимальное состояние и для вычисления эффективности затрат при использовании таких способов.
