    • The invention relates to a heat transfer method that uses a composition containing from 60 to 95 wt % of 1,1,1,3,3-pentafluoropropane and from 5 to 40 wt % of at least one hydrocarbon selected from n-pentane, isopentane and cyclopentane. The invention more particularly relates to a heat transfer method that successively includes the step of evaporating a refrigerant fluid, a compression step, the step of condensing said fluid at a temperature higher than or equal to 35° C., and preferably between 70° C. and 140° C., and the step of expanding said fluid, characterized in that the refrigerant fluid includes from 60 to 95 wt % of 1,1,1,3,3-pentafluoropropane and from 5 to 40 wt % of at least one hydrocarbon selected from n-pentane, isopentane and cyclopentane.
    • 本发明涉及使用含有60〜95重量%的1,1,1,3,3-五氟丙烷和5〜40重量%的至少一种选自正戊烷,异戊烷的烃的组合物的传热方法 和环戊烷。 本发明更具体地涉及一种传热方法,其依次包括蒸发制冷剂流体的步骤,压缩步骤,在高于或等于35℃,优选70℃的温度下冷凝所述流体的步骤 和140℃,以及膨胀所述流体的步骤,其特征在于,所述制冷剂流体包括60至95重量%的1,1,1,3,3-五氟丙烷和至少至少5重量%至40重量% 一种选自正戊烷,异戊烷和环戊烷的烃。

    • The invention relates to the use of a composition as an agent for blowing a projected biocomponent polyurethane foam, said composition including 1-chloro-3,3,3-trifluoropropane and/or 2-chloro-3,3,3-trifluoropropene and at least one additional compound selected from among hydrochlorofluoroolefins, hydrofluoroolefins, hydrochloroolefins, hydrofluorocarbons, hydrochlorofluorocarbons, hydrocarbons, substituted or non-substituted ethers, substituted or non-substituted alcohols, substituted or non-substituted aldehydes, substituted or non-substituted ketones and substituted or non-substituted esters. Said composition has a boiling point greater than or equal to 20° C. The invention also relates to a method for manufacturing polyurethane foam on the basis of the use above and moreover relates to specific compositions that are appropriate for implementing the invention.
