Title (EN) REFRIGERANT FLUID CIRCUIT COMPRISING A COMPRESSOR COMPRISING AT LEAST TWO COMPRESSION STAGES
(FR) CIRCUIT DE FLUIDE REFRIGERANT COMPRENANT UN COMPRESSEUR COMPORTANT AU MOINS DEUX ETAGES DE COMPRESSION
Abstract:
(EN) The invention relates to a refrigerant fluid circuit 1 intended to equip a motor vehicle for the air-conditioning of the vehicle interior, the refrigerant fluid circuit 1 comprising: - a compressor 2 comprising at least a first compression stage 3 and a second compression stage 4, - a heat exchanger 5 comprising at least a first portion 6 and a second portion 7 through which the refrigerant fluid travels, characterized in that the refrigerant fluid circuit 1 comprises another heat exchanger 14 designed to perform an exchange of heat between, on the one hand, the refrigerant fluid circulating between the first stage 3 of the compressor 2 and the second stage 4 of the compressor 2 and, on the other hand, the refrigerant fluid circulating between the first and second portions 6, 7 of the first heat exchanger 5.
(FR) L'invention concerne un circuit de fluide réfrigérant 1 destiné à équiper un véhicule automobile pour en climatiser l'habitacle, le circuit de fluide réfrigérant 1 comprenant : - un compresseur 2 comportant au moins un premier étage de compression 3 et un deuxième étage de compression 4, - un échangeur de chaleur 5 comprenant au moins une première portion 6 et une deuxième portion 7 parcourues par le fluide réfrigérant, caractérisé en ce que le circuit de fluide réfrigérant 1 comprend un autre échangeur de chaleur 14 agencé pour réaliser un échange de chaleur entre, d'une part, le fluide réfrigérant circulant entre le premier étage 3 du compresseur 2 et le deuxième étage 4 du compresseur 2 et, d'autre part, le fluide réfrigérant circulant entre les première et deuxième portions 6, 7 du premier échangeur de chaleur 5.
