Abstract
1. Способ автоматического управления аппаратами воздушного охлаждения, заключающийся в измерении температуры охлаждаемой среды на выходном коллекторе многосекционной установки охлаждения и включении/отключении части электродвигателей вентиляторов секций установки в функции измеренной температуры охлаждаемой среды, отличающийся тем, что для каждой секции теплообменников при включенном двигателе вентилятора измеряют электрическую мощность, потребляемую им из сети, температуру на входе и выходе секции, периодически определяют разность измеренных температур на входе и выходе, а также отношение разности температур к измеренной мощности, принимают вычисленные отношения за показатели эффективности работы секций теплообменников, периодически запоминают и сравнивают их, при этом в случае отклонения температуры охлаждаемой среды на выходном коллекторе УОГ ниже зоны допустимых отклонений с выдержкой времени отключают вентилятор секции теплообменника с наименьшим показателем эффективности, а в случае отклонения температуры выше зоны допустимых отклонений подключают вентилятор секции теплообменника с наибольшим показателем эффективности среди отключенных. ! 2. Способ по п.1, отличающийся тем, что зону допустимых отклонений температуры среды на выходном коллекторе установки охлаждения принимают равной 5-7% от заданного (требуемого) значения температуры. ! 3. Способ по п.1, отличающийся тем, что выдержку времени на отключение вентилятора секции, имеющей наименьший показатель эффективности, принимают в 5-7 раз больше постоянной времени нагрева секции установки охлаждения. ! 4. Способ по п.1, отличающийся тем 1. The method of automatic control of air-cooled devices, which consists in measuring the temperature of the medium to be cooled at the output manifold of a multi-section cooling unit and turning on / off part of the fan motors of the unit sections as a function of the measured temperature of the medium to be cooled, characterized in that for each section of the heat exchangers when the fan motor is switched on, the electric power consumed by him from the network, the temperature at the inlet and outlet of the section, periodically determine the different The measured temperature at the inlet and outlet, as well as the ratio of the temperature difference to the measured power, take the calculated ratios for the performance indicators of the heat exchanger sections, periodically remember and compare them, in case of deviation of the temperature of the cooled medium at the exhaust gas collector below the zone of permissible deviations with with a delay of time, turn off the fan of the heat exchanger section with the lowest efficiency indicator, and in case of temperature deviation above the zone of permissible deviations, I connect heat exchanger section of the fan with the most efficiency indicator among the disabled. ! 2. The method according to claim 1, characterized in that the zone of permissible deviations of the temperature of the medium at the output manifold of the cooling installation is taken to be 5-7% of the set (required) temperature value. ! 3. The method according to claim 1, characterized in that the time delay for turning off the fan of the section having the lowest efficiency indicator is 5-7 times longer than the constant heating time of the section of the cooling installation. ! 4. The method according to claim 1, characterized in
