Description
Изобретение относится к холодильной технике, а именно к рабочим веществам для регенеративных холодильных машин. Известно рабочее тело холодильной э машины, включающее фреон-1ЗВ1 и фреон-12 Г1] .The invention relates to refrigeration, and in particular to working substances for regenerative refrigeration machines. It is known working fluid refrigeration e machines, including Freon-1ZV1 and Freon-12 G1].
Недостатком этого рабочего тела является невысокая энергетическая эффективность.The disadvantage of this working fluid is its low energy efficiency.
. Известно также рабочее тело для низкотемпературных регенеративных холодильных машин, содержащее фреон-23 и фреон-12 [2] .. It is also known a working fluid for low-temperature regenerative refrigeration machines containing Freon-23 and Freon-12 [2].
Недостатком этого рабочего тела 15 является его недостаточная эффективность при температурах кипения минус 70 - минус 50°С.The disadvantage of this working fluid 15 is its lack of efficiency at boiling points minus 70 - minus 50 ° C.
Цель изобретения - повышение энергетической эффективности холодиль- 20 ных машин при температурах кипения рабочего тела в испарителе минус 70 минус 50иС.The purpose of the invention is to increase the energy efficiency of refrigeration machines at boiling temperatures of the working fluid in the evaporator minus 70 minus 50 and C.
Цель достигается тем, что рабочее тело дополнительно содержит фреОН-13В1 при следующем соотношении компонентов, вес.%:The goal is achieved in that the working fluid additionally contains freon-13B1 in the following ratio of components, wt.%:
Фреон-2340-50Freon-2340-50
Фреон-13В125-30Freon-13V125-30
Фреон-12 25-3030Freon-12 25-3030
Такой состав смеси позволяет получить в испарителе одноступенчатой регенеративной холодильной машины температуру кипения рабочего тела до минус 80°С с высокой энергетической эффективностью, что подтверждается экспериментальными данными.This composition of the mixture allows to obtain in the evaporator of a single-stage regenerative refrigeration machine the boiling temperature of the working fluid up to minus 80 ° C with high energy efficiency, which is confirmed by experimental data.
Это видно из следующей таблицы.This can be seen from the following table.
