Abstract
(EN)
A refrigeration cycle device (100) comprises a housing (1) and a refrigerant circuit (10). The housing (1) includes a storage chamber (11) and a flow path (12). The refrigerant circuit (10) is housed in the housing (1) and includes a compressor (2), a condenser (3), an expansion device (4), an evaporator (5), and a backflow prevention device (6). The expansion device (4) includes an opening-closing valve (4a) that is configured so as to be capable of opening and closing the refrigerant circuit (10). The refrigerant circuit (10) is configured so as to be capable of executing a pump-down operation in which the compressor (2) is operated while the refrigerant is prevented from flowing backward from the compressor (2) to the evaporator (5) by the backflow prevention device (6) and the refrigerant circuit (10) is closed by the opening-closing valve (4a).

L'invention concerne un dispositif à cycle frigorifique (100) comprenant une enveloppe (1) et un circuit (10) de fluide frigorigène. L'enveloppe (1) comprend une chambre de stockage (11) et un circuit d'écoulement (12). Le circuit (10) de fluide frigorigène est logé dans l'enveloppe (1) et comprend un compresseur (2), un condenseur (3), un dispositif d'expansion (4), un évaporateur (5) et un antirefouleur (6). Le dispositif d'expansion (4) comprend une soupape d'ouverture-fermeture (4a) conçue afin de pouvoir ouvrir et fermer le circuit (10) de fluide frigorigène. Le circuit (10) de fluide frigorigène est conçu afin de pouvoir effectuer un fonctionnement de pompage vers le bas dans lequel le compresseur (2) est actionné pendant que le fluide frigorigène est empêché de couler du compresseur (2) de retour vers l'évaporateur (5) à l'aide de l'antirefouleur (6), et le circuit (10) de fluide frigorigène est fermé par la soupape d'ouverture-fermeture (4a).
