Method of operating a heat pump or a thermal engine with a chloro-fluorinated hydrocarbon having an increased thermal stability

摘要

A method of operating a heat pump or a thermal engine with the vaporization and the condensation of a heat transfer fluid. The fluid is a chlorofluorinated hydrocarbon with 2 or 3 carbon atoms, a hydrogen atom, at least one chlorine atom per molecule and at most one chlorine atom per carbon atom, with the remainder consisting of fluorine, and said fluid having a critical temperature of at least 140 DEG C.
