Изобретение относится к области холодильной техники, главным образом к бытовым холодильным агрегатам, и может быть использовано в среднетемпературном холодильном оборудовании, кондиционерах и в исследовательских целях. Настоящим изобретением предложены рабочая смесь для холодильных машин на основе дифторэтана (R152а) с добавлением изобутана (R600а). Предложен также диапазон концентраций компонентов, обеспечивающий азеотропный характер смеси: R152а от 60 до 75 мас.%, R600а от 25 до 40 мас.%. В указанном диапазоне концентрации холодильный коэффициент предложенной рабочей смеси превышает соответствующий показатель для R12. Смесь имеет нулевой озоноповреждающий потенциал, а составляющие ее компоненты обладают близкими молекулярными массами.The invention relates to the field of refrigeration, mainly to household refrigeration units, and can be used in medium temperature refrigeration equipment, air conditioners and for research purposes. The present invention proposed a working mixture for refrigerators based on difluoroethane (R152a) with the addition of isobutane (R600a). A range of component concentrations is also proposed, providing the azeotropic nature of the mixture: R152a from 60 to 75 wt.%, R600a from 25 to 40 wt. In the specified concentration range, the cooling coefficient of the proposed working mixture exceeds the corresponding figure for R12. The mixture has a zero ozone damaging potential, and its constituent components have similar molecular masses.
