(54) ХОЛОДИЛЬНЫЙ АГЕНТ(54) REFRIGERANT AGENT

Claims (1)

Изобретение относитс  к получению кри генных температур, в частнодти к охлажде нию различных устройств с помощью дроссельных регенеративных циклов до криоген ных температур, в том числе до температуры кипени  жидкого азота. Известно применсйие смесей на основе азота, неона и углеводородов метанового р да, отличительным признаком которых  вл етс  растворимость вспомогательных компонентов в основном. Так, например, смесь состава: азот- 30-50%, этан-25- 35%, пропан-25-35% ij . Указанные смеси используютс  преимущественно в криогенных системах с трехступенчатым компрессором, так как оптимальное рабочее давление их лежит в пределах 70-120 кг/см. Цель изобретени  - повышение экономи ности в области давлений сжати  до 304О кг/см. Это достигаетс  тем, что компоненты смеси вз а;ь;г в следующем соотношении (в объемных %) Азот - 26 ± 1 Метан -16 + 1 Этан - 16 1 1 Пропан -16+1 Изобутан - 26 + 1 Как показывают исследовани  предлагаемого компонента, предлагаемый холодильный агент в диапазоне 30-40 кг/см обеспечивает удельную объемную холодо- производительность 20-25 Вт/нм /час и имеет термодинамический к. п. д. 75-90%. Известные смеси в указанном диапазоне имеют термодинамический к.п.д. 102О% . Применение холодильного агента в дроссельных криогенных системах позволит использовать двухступенчатые компрессоры , имеющие больший ресурс и надежность. Формула изобретени  Холодильный агент дл  регенеративного цикла на основе смеси азота с углеводороThe invention relates to the production of cryogenic temperatures, in particular, to the cooling of various devices using throttle regenerative cycles to cryogenic temperatures, including the boiling point of liquid nitrogen. It is known to use mixtures based on nitrogen, neon and methane hydrocarbons, the distinguishing feature of which is the solubility of the auxiliary components mainly. For example, a mixture of the composition: nitrogen - 30-50%, ethane-25- 35%, propane-25-35% ij. These mixtures are used predominantly in cryogenic systems with a three-stage compressor, since their optimum working pressure lies in the range of 70-120 kg / cm. The purpose of the invention is to increase the economy in the field of compression pressures up to 304 O kg / cm. This is achieved by the fact that the mixture components take up a; b; g in the following ratio (in volume%) Nitrogen - 26 ± 1 Methane -16 + 1 Ethane - 16 1 1 Propane -16 + 1 Isobutane - 26 + 1 the component offered by the refrigerating agent in the range of 30–40 kg / cm provides a specific volume cooling capacity of 20–25 W / nm / hour and has a thermodynamic efficiency of 75–90%. Known mixtures in this range have a thermodynamic efficiency. 102%. The use of refrigerant in throttling cryogenic systems will allow the use of two-stage compressors with greater resource and reliability. Refrigerant for a regenerative cycle based on a mixture of nitrogen and hydrocarbons.
