It is shown that the fundamental theoretical models do not contain adjustable parameters and allows the description of transport properties of pure HCFCand HFC refrigerants, and their mixtures including polar fluids. The validity of this scheme was confirmed by comparison of calculated results to experimental values made for sixth pure refrigerants, two ternary and one binary mixtures (R32, R123, R124, RI25, R134a, Rl43a, R404A, R407C and R410A). Agreement of the present values with those of some experimental results are quite satisfactory.</p></abstract><trans-abstract xml:lang="ru"><p>Разработка альтернативных хладагентов инициировала появление значительного объема экспериментальных исследований за относительно небольшой период времени - с 90-х годов XX в. до начала нынешнего. Чтобы осмыслить качество полученной за столь короткое время теплофизической информации, нужна невозмутимая, спокойная и продолжительная работа, тем более что есть о чем поразмыслить: расхождения между результатами многих работ выходят за рамки погрешности эксперимента.</p></trans-abstract><kwd-group xml:lang="en"><kwd>coolant</kwd><kwd>thermophysical information</kwd><kwd>experimental error</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>хладагент</kwd><kwd>теплофизическая информация</kwd><kwd>погрешность эксперимента</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Алтунин В.В.
