The present disclosure relates to a method for exchanging heat in a vapor compression heat transfer system. In particular, it relates to use of an intermediate heat exchanger to improve performance of a vapor compression heat transfer system utilizing a working fluid comprising at least one fluoroolefin. In addition, the present disclosure relates to a vapor compression heat transfer system comprising an intermediate heat exchanger in combination with a dual-row evaporator or a dual-row condenser, or both. La présente invention concerne un procédé déchange de chaleur dans un système de transfert de chaleur à compression de vapeur. En particulier, linvention concerne lutilisation dun échangeur de chaleur intermédiaire pour améliorer le rendement dun système de transfert de chaleur à compression de vapeur utilisant un fluide actif comprenant au moins une oléfine fluorée. De plus, la présente invention concerne un système de transfert de chaleur à compression de vapeur comprenant un échangeur de chaleur intermédiaire en association avec un évaporateur double flux ou un condenseur double flux, ou les deux.
