Abstract
Способ служит для регулировки сдвоенной теплообменной системы, которая имеет первый блок (1) теплообменника и второй блок (2) теплообменника. Первый поток (3) текучей среды протекает через теплообменную систему, будучи разделен на первый частичный поток (4) и второй частичный поток (5). Второй поток (6) текучей среды проводится в противотоке к первому частичному потоку (4) через первый блок (1) теплообменника. Третий поток (7) текучей среды проводится в противотоке ко второму частичному потоку (5) через второй блок (2) теплообменника. На одном из двух блоков (1, 2) теплообменника измеряется промежуточная температура (TI). В зависимости от текущего значения этой промежуточной температуры (TI) устанавливается, какая часть первого потока (3) текучей среды поступает в первый частичный поток (4), а какая во второй частичный поток (5). Регулировка достигает уменьшения нагрузки теплообменника посредством изменения загрузки, удерживая колебания промежуточной температуры на минимально возможном уровне.
