Abstract
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.
