COMPOSITIONS FOR HEAT TRANSMISSION

摘要

FIELD: chemistry.SUBSTANCE: invention relates to versions of composition for heat transmission. One of composition versions contains (i) from about 20 to about 90 wt % of R-1234yf; (ii) from about 10 to about 60 wt % of R-134a and (iii) from about 1 to about 20 wt % of R-32. Invention also relates to a number of versions of composition application.EFFECT: composition has lower value of global warming potential and at the same time is characterised by productivity and energy efficiency.56 cl, 7 dwg
