Abstract
(EN)
In a refrigeration cycle device (1), an injection pipe (31) and an economizer heat exchanger (32) are provided to a main refrigerant circuit (20). Further, the refrigeration cycle device (1) is provided with a sub refrigerant circuit (80) which includes a sub utilization-side heat exchanger (85). In the refrigeration cycle device (1), the sub utilization-side heat exchanger (85) is made to function as: an evaporator for a sub refrigerant so as to cool a main refrigerant that was cooled in the economizer heat exchanger (32); or as a heat radiator for the sub refrigerant so as to heat the main refrigerant that was cooled in the economizer heat exchanger (32).
(FR)
Dans le dispositif à cycle frigorifique (1) de la présente invention, un tuyau d'injection (31) et un échangeur de chaleur économiseur (32) sont disposés sur un circuit de fluide frigorigène principal (20). En outre, le dispositif à cycle frigorifique (1) est pourvu d'un circuit de fluide frigorigène secondaire (80) qui comprend un échangeur de chaleur (85) côté utilisation secondaire. Dans le dispositif à cycle frigorifique (1), l'échangeur de chaleur (85) côté utilisation secondaire est conçu pour fonctionner comme : un évaporateur pour un fluide frigorigène secondaire de façon à refroidir un fluide frigorigène principal qui a été refroidi dans l'échangeur de chaleur économiseur (32); ou comme radiateur pour le fluide frigorigène secondaire de façon à chauffer le fluide frigorigène principal qui a été refroidi dans l'échangeur de chaleur économiseur (32).
