Background: Nitric oxide NO is used in medicine and as an additive in artificial atmospheres for boxes and incubators. It is mainly obtained by a plasma method, passing a gas discharge through air or a mixture of nitrogen and oxygen. The use of effective conditions for obtaining this gas will optimize the design of the device and increase the NO yield while maintaining the input power.

Aim: Evaluation and analysis of the influence of pulse repetition frequency on the amount of nitrogen monoxide produced in the discharge.

Methods: To experimentally evaluate the effect of pulse repetition frequency on the change in the amount of NO obtained, an experiment was conducted for which a test bench was assembled based on a plasma chemical reactor (PCR) and an OPTIMA 7 gas analyzer, which was used to record NO concentration values corresponding to a given pulse repetition frequency.

Results: As a result of the work carried out, the existence of regions in which the concentrations of nitrogen mono- and dioxide change according to a nonlinear law was demonstrated, presumably associated with the resonant characteristics of the PCR parts, including the dependence of the reactive and active resistance on the PCR design.

Conclusion: The analysis and calculations revealed that the evaporation surface area directly impacts the amount of evaporated boil-off gas and the power consumption of the boil-off gas compressor. The data obtained suggest the possibility of creating low-power life support systems, such as incubators, as well as closed-loop therapeutic treatment rooms based on a device for generating NO.

Обоснование. Монооксид азота NO используется в медицине и в качестве добавок в искусственной атмосфере для боксов и инкубаторов. Получают его преимущественно плазменным методом, пропуская через воздух или смесь азота и кислорода газовый разряд. Использование эффективных условий для получения данного газа позволит оптимизировать конструкцию устройства и повысить выход NO при сохранении вкладываемой мощности.

Цель — оценка и анализ влияния частоты повторения импульсов на количество, получаемого в разряде монооксида азота.

Методы. Для экспериментальной оценки влияния частоты повторения импульсов на изменение получаемого количества монооксида азота NO был проведен эксперимент, для которого был собран стенд на основе плазмохимического реактора (ПХР) и газоанализатора OPTIMA 7, с помощью которого регистрировались значения концентраций NO, соответствующие заданной частоте повторения импульсов.

Результаты. В результате проделанной работы было показано существование областей, в которых происходит изменение концентраций моно- и диоксида азота по нелинейному закону, предположительно связанное с резонансными характеристиками частей ПХР, в том числе с зависимостью реактивного и активного сопротивления от конструкции ПХР.

Заключение. Проведённый анализ и расчёты показали, что площадь зеркала испарения напрямую влияет на величину испарившегося отпарного газа и потребляемую мощность компрессора отпарного газа. Полученные данные позволяют говорить о возможности создания маломощных системах жизнеобеспечения, такие как инкубаторы, а также замкнутых системы терапевтических боксов для лечения людей на базе устройства для генерации NO.
