摘要:
A binary composition of 1,3,3,3-tetrafluoropropene and ammonia, as well as to the use thereof, in particular as a heat-transfer fluid. The composition may include from 40% to 99% of ammonia and from 1% to 60% of 1,3,3,3-tetrafluoropropene; preferably from 60% to 98% of ammonia and from 2% to 40% of 1,3,3,3-tetrafluoropropene; preferably from 70% to 95% of ammonia and from 5% to 30% of 1,3,3,3-tetrafluoropropene; preferably from 75% to 90% of ammonia and from 10% to 25% of 1,3,3,3-tetrafluoropropene; preferably from 78% to 85% of ammonia and from 15% to 22% of 1,3,3,3-tetrafluoropropene. The 1,3,3,3-tetrafluoropropene may be in the cis form or in the trans form or is a mixture of cis form and trans form and in which, preferably, at least 80% or at least 90% or at least 95% or at least 98% or at least 99% of the 1,3,3,3-tetrafluoropropene is in the trans form.
摘要:
A composition based on 3,3,3-trifluoropropene and ammonia, and to the use thereof, especially as a heat transfer fluid. A heat-transfer composition including the composition based on 3,3,3-trifluoropropene and ammonia and also one or more additives chosen from lubricants, stabilizers, surfactants, tracers, fluorescers, odorant agents and solubilizers, and mixtures thereof. A process for heating or cooling a fluid or a body by means of a vapor compression circuit containing a heat-transfer fluid, said process successively including evaporation of the heat-transfer fluid, compression of the heat-transfer fluid, condensation of the heat fluid and depressurization of the heat-transfer fluid, in which the heat-transfer fluid is a composition based on 3,3,3-trifluoropropene and ammonia.

摘要:
The present invention relates to a heat transfer process using a composition containing hydro(chloro)fluoroolefins. It more particularly relates to a heat transfer process that successively comprises a step of evaporation of a refrigerant; a step of compression, a step of condensation of said refrigerant at a temperature greater than or equal to 70° C. and a step of expansion of said refrigerant characterized in that the refrigerant comprises at least one hydrofluoroolefin having at least four carbon atoms represented by the formula (I) R1CH═CHR2 in which R1 and R2 independently represent alkyl groups having from 1 to 6 carbon atoms, substituted with at least one fluorine atom, optionally with at least one chlorine atom.
