| 摘要 |
The invention relates to a process for producing heat and/or cold by means of a compression engine operating with a nonazeotropic mixed working fluid. It is characterized in that the mixed working fluid, partially vaporized at the output of evaporator (E1), is contacted, in heat exchange conditions, in (E2), with the compression system (K), in order to continue or complete the vaporization of the fluid which is then compressed, condensed in exchanger (E3), expanded through an expansion valve (V) and then recycled to evaporator (E1).
