摘要

heat quake composition and device, use of a composition, blowing agent, foaming composition, foam, sprayable composition, method for cooling an article, for heating an article, for extracting a biomass substance, for cleaning an article , from extracting a material from an aqueous solution, to extracting a material from a particulate solid matrix, to reforming a heat transfer device, to reducing environmental impact, to preparing the composition and to generating effect gas emission credit greenhouse and mechanical power generation device. The invention provides a heat transfer composition comprising (i) a first component selected from trans-1,3,3,3-tetrafluoto-propene (r-1234ze (e)), cis-1,3,3,3- tetrafluoto-propene (r-1234ze (z)) and mixtures thereof; (ii) carbon dioxide (r-744); and a third component selected from 2,3,,3,3-tetrafluoto-propene (r-1234yf), 3,3,3-tetrafluoto-propene (r-1234zf), and mixtures thereof.
