Title
(EN) HEAT EXCHANGER ARRANGEMENT
(FR) AGENCEMENT D'ECHANGEUR DE CHALEUR
Abstract
(EN)
A refrigeration system includes a compressor for driving a refrigerant along a flow path in at least a first mode of system operation; a first heat exchanger along the flow path downstream of the compressor in the first mode; a second heat exchanger along the flow path upstream of the compressor in the first mode; and a pressure regulator or expansion device in the flow path downstream of the first heat exchanger and upstream of the second heat exchanger in the first mode, wherein the first heat exchanger is positioned within a housing which defines a flow path for heat exchange fluid and the housing defines a zone of reduced flow area along the flow path, and wherein the first heat exchanger is positioned in the zone of reduced flow area.
(FR)
Système de refroidissement qui comporte un compresseur permettant d'entraîner un liquide de refroidissement le long d'un trajet d'écoulement dans au moins un premier mode de fonctionnement du système; un premier échangeur de chaleur le long du trajet d'écoulement en aval du compresseur dans le premier mode; un second échangeur de chaleur le long du trajet d'écoulement en amont du compresseur dans le premier mode, et un régulateur de pression ou un dispositif d'expansion dans le trajet d'écoulement en aval du premier échangeur de chaleur et en amont du second échangeur de chaleur dans le premier mode, le premier échangeur de chaleur étant placé dans un boîtier qui délimite un trajet d'écoulement pour un fluide d'échange de chaleur, lequel boîtier définit une zone à écoulement réduit le long du trajet d'écoulement, le premier échangeur de chaleur étant placé dans la zone à écoulement réduit.
