Abstract
(EN)
This vehicle-mounted cooling system comprises: an air-conditioning refrigerant circuit (31) that is provided with a refrigerant passage (32), a compressor (33), a heat-source-side heat exchanger (34), and a use-side heat exchanger (35); a battery (51); and a battery cooling unit (52) that cools the battery by circulating a refrigerant. The control device (60) controls the driving state of the compressor on the basis of an air conditioning request and a battery cooling request. The control device is provided with: an abnormality determination unit that determines if an abnormality has occurred in the air conditioning refrigerant circuit; and a control mode change unit that changes the control mode of the refrigerant circulation in the air-conditioning refrigerant circuit while continuing to cool the battery with the battery cooling unit under a situation where there is a battery cooling request and it is determined that the abnormality has occurred.

L'invention concerne un système de refroidissement monté sur véhicule comprenant : un circuit de fluide frigorigène de climatisation (31) qui est pourvu d'un passage de fluide frigorigène (32), d'un compresseur (33), d'un échangeur de chaleur côté source de chaleur (34) et d'un échangeur de chaleur côté utilisation (35) ; une batterie (51) ; et une unité de refroidissement de batterie (52) qui refroidit la batterie en faisant circuler un fluide frigorigène. Le dispositif de commande (60) commande l'état d'entraînement du compresseur sur la base d'une demande de climatisation et d'une demande de refroidissement de batterie. Le dispositif de commande comprend : une unité de détermination d'anomalie qui détermine si une anomalie s'est produite dans le circuit de fluide frigorigène de climatisation ; et une unité de changement de mode de commande qui modifie le mode de commande de la circulation de fluide frigorigène dans le circuit de fluide frigorigène de climatisation tout en continuant à refroidir la batterie avec l'unité de refroidissement de batterie dans une situation dans laquelle il existe une demande de refroidissement de batterie et il est déterminé que l'anomalie s'est produite.
