Изобретение относитс  к области получени  криогенных температур, в частности к охлаждению различных устройств с помощью дроссельных реге неративных циклов до криогенных температур , в том числе до температур кипени  жидкого азота. Известен холодильный агент в виде смеси на основе азота и углеводородов метанового р да, каждый из ком понентов которых не растворим в основном хладагенте, но растворим во вспомогательных компонентах l . Оптимальное давление сжати  этой смеси лежит в пределах 60-120 кг/см . Известен также холодильный дл  регенеративного дроссельного цик ла, содержсиций смесь азота с метаном этаном, пропаном и изобутаном 2 . Известный хладагент имеет оптимал ное давление сжати , лежащее в преде лах 30-40 кг/см Целью изобретени   вл етс  сниже ние рабочего давлени  до 5-15 кг/см Цель достигаетс  тем, что компоненты смеси вз ты в следующем соотношении , об.%: Азот10-15 Метан10-15 Этан10-15 Пропан Изобутан Как показывают исследовани , данный холодильный агент в диапазоне рабочих давлений 5-15 кг/см обеспечивает удельную объемную холодопроизводительность 2-15 вт/км /час и имеет термодинамический КПД 10-60%. Известные смеси в указанном диапазоне давлений имеют термодинамический КПД менее 5%. Применение данного холодильного агента в регенеративных дроссельных циклах позволит использовать одноступенчатые компрессоры, имеющие небольшие габариты, большой ресурс и надежность . Формула изобретени  Холодильный агент дл  регенеративного дроссельного цикла, содержащий смесь азота с метаном, этаном, пропаном и изобутаном, отличающийс  тем, что, с целью снижени  рабочего давлени , компоненты смеси вз ты в следующем соотношении, об.%: 3637417 Изобутан40-60 Источники информации, прин тые во внимание при экслестизе:№ 4 Авторское свидетельство СССР 333858, кл. С 09 К 5/00, 1970 The invention relates to the field of obtaining cryogenic temperatures, in particular, to the cooling of various devices using throttle regenerative cycles to cryogenic temperatures, including boiling temperatures of liquid nitrogen. A refrigerant is known in the form of a mixture based on nitrogen and methane hydrocarbons, each of whose components is insoluble in the main refrigerant, but soluble in auxiliary components l. The optimum compression pressure of this mixture is in the range of 60-120 kg / cm. Also known is refrigeration for a regenerative choke cycle, a mixture of nitrogen and methane with ethane, propane and isobutane 2. The known refrigerant has an optimal compressive pressure in the range of 30-40 kg / cm. The aim of the invention is to reduce the operating pressure to 5-15 kg / cm. The goal is achieved by taking the mixture components in the following ratio, vol.%: Nitrogen 10-15 Methane 10-15 Ethan 10-15 Propane Isobutane Research shows that this refrigerant in the operating pressure range of 5-15 kg / cm provides a specific volume cooling capacity of 2-15 W / km / h and has a thermodynamic efficiency of 10-60%. Known mixtures in the specified pressure range have a thermodynamic efficiency of less than 5%. The use of this refrigerant in regenerative throttle cycles will allow the use of single-stage compressors with small dimensions, long life and reliability. Claims: Refrigerant for regenerative throttle cycle containing a mixture of nitrogen with methane, ethane, propane and isobutane, characterized in that, to reduce the working pressure, the components of the mixture are taken in the following ratio,%: 3637417 Isobutane 40-60 Sources of information , taken into account during the execution: No. 4 Author's Certificate of the USSR, 333858, cl.
