Изобретение относитс к холодильной технике, а именно к рабочим веществам дл низкотемпературных регенеративных машин.The invention relates to refrigeration engineering, in particular to working substances for low-temperature regenerative machines.
Известно рабочее тело дл низкотемпературных регенеративных холодильных машин, составленное из метана , этана, пропана и бутана 0-J Known working fluid for low-temperature regenerative chillers, composed of methane, ethane, propane and butane 0-J
Недостатком этого рабочего тела вл етс его неэффективность при работе при низких температурах охлаждени .The disadvantage of this working fluid is its inefficiency when operating at low cooling temperatures.
Известно также рабочее тело дл низкотемпературных регенеративных холодильных машин, содержащее фреОН-13В1 и фреон-12 Г2 .It is also known working medium for low-temperature regenerative chillers containing freon-13B1 and freon-12 G2.
В этом рабочем теле весова концентраци фреона-13В1 поддерживаетс в пределах 10-40%.In this working body, the weight concentration of Freon-13B1 is maintained within 10-40%.
Недостатком данного рабочего тела вл етс недостаточна его эффективность при работе одноступенчатых холодильных машин при температурах охлаждени ниже минус .The disadvantage of this working fluid is its lack of efficiency in the operation of single-stage chillers at cooling temperatures below minus.
Цель изобретени - повышение энергетической эффективности холодильных машин при температурах охладени минус 70 - минус 50°С.The purpose of the invention is to increase the energy efficiency of refrigerators at cooling temperatures of minus 70 - minus 50 ° C.
Указанна цель достигаетс тем, что рабочее тело дополнительно содержит этан () при следующем соотношении компонентов, вес.%; Этан () 40-50 Фреон-13В1 25-30 Фреон-12 25-30 Такой состав смеси позвол ет получить в испарителе одноступенчатой регенеративной холодильной машины температуру кипени рабочего тела This goal is achieved by the fact that the working fluid additionally contains ethane () in the following ratio of components, wt.%; Ethane () 40-50 Freon-13B1 25-30 Freon-12 25-30 Such a composition of the mixture allows to obtain in the evaporator of a single-stage regenerative refrigeration machine
0 до минус 80°С и повышает энергетическую эффективность xoлoдиJ ьнoй машины при температурах кипени от минус 70°С до минус 50°С, что подтверждаетс результатами экспери5 ментов.0 to minus 80 ° С and increases the energy efficiency of the cold machine at boiling points from minus 70 ° С to minus 50 ° С, which is confirmed by the results of experiments.
Добавление этана в рабочее телодает возможность получать температуру кипени в испарителе холодильной машины до минус , а фре0 ОН-13В1 и фреон-12 обеспечивают необходимую степень сжати компрессора .The addition of ethane to the operating body makes it possible to obtain the boiling point in the evaporator of the refrigerating machine to minus, and OH-13B1 and Freon-12 provide the necessary compression ratio of the compressor.
