Abstract
(EN) A heat pump system, which relates to the technical field of heat pump units. The heat pump system comprises an electromagnetic suspension centrifugal compressor (1) and further comprises a switching communication device (3) and a first electric valve (14); an exhaust pipe of the electromagnetic suspension centrifugal compressor (1) is connected to a first interface of the switching communication device (3) by means of a first unidirectional valve (2), and a suction pipe is connected to a third interface of the switching communication device (3); and the first electric valve (14) is arranged in parallel to the electromagnetic suspension centrifugal compressor (1). The heating function of an electromagnetic suspension centrifugal compressor unit is realized by means of the switching communication device (3); meanwhile, the configured first electric valve (14) is opened before start up of the electromagnetic suspension centrifugal compressor so as to adjust the pressure difference of a high pressure side and a low pressure side of the compressor; and the first electric valve is opened before closing of the compressor so as to reduce the shutdown pressure ratio so that the compressor may 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.
