Abstract
(EN) Embodiments of the present disclose disclose a heat pump system, which belongs to the field of heat pump unit technologies. The heat pump system includes a magnetic levitation centrifugal compressor, and further includes a switching communication device and a first electric valve; wherein an exhaust pipe of the magnetic levitation centrifugal compressor is connected to a first interface of the switching communication device through a first check valve, and an air suction pipe of the magnetic levitation centrifugal compressor is connected to a third interface of the switching communication device; and the first electric valve is arranged in parallel with the magnetic levitation centrifugal compressor. According to the above embodiments, by using the switching communication device, the heating function of magnetic levitation centrifugal compressor units is realized; at the same time, by setting the first electric valve, which is turned on before the magnetic levitation centrifugal compressor is on to adjust a differential pressure between a high-pressure side and a low-pressure side of the compressor or is turned on before the compressor is off to reduce the shutdown pressure ratio, the compressor can run smoothly.
(FR) L'invention concerne un système de pompe à chaleur, se rapportant au domaine technique des ensembles pompe à chaleur. Le système de pompe à chaleur comprend un compresseur centrifuge à suspension électromagnétique (1) et comprend en outre un dispositif de communication à commutation (3) et une première soupape électrique (14) ; un tuyau d'échappement du compresseur centrifuge à suspension électromagnétique (1) est relié à une première interface du dispositif de communication à commutation (3) au moyen d'une première soupape unidirectionnelle (2), et un tuyau d'aspiration est relié à une troisième interface du dispositif de communication à commutation (3) ; et la première soupape électrique (14) est agencée parallèlement au compresseur centrifuge à suspension électromagnétique (1). La fonction de chauffage d'un ensemble compresseur centrifuge à suspension électromagnétique est effectuée au moyen du dispositif de communication à commutation (3) ; entre-temps, la première soupape électrique configurée (14) est ouverte avant le démarrage du compresseur centrifuge à suspension électromagnétique, afin de régler la différence de pression d'un côté haute pression et d'un côté basse pression du compresseur ; et la première soupape électrique est ouverte avant la fermeture du compresseur afin de réduire le rapport de pression d'arrêt, de sorte que le compresseur puisse fonctionner sans entraves.
