Le système améliore l'efficacité de chauffage en éliminant les problèmes conventionnels liés à la baisse de la température extérieure en hiver. En outre, comme l'opération de commutation entre les modes de chauffage et de refroidissement est rendue possible par le simple contrôle d'un tuyau de milieu chauffant, le système peut être contrôlé facilement et la stabilité des opérations de chauffage et de refroidissement est optimisée. Le système de chauffage et de refroidissement à pompe à chaleur hybride selon l'invention comprend : un compresseur ; un échangeur de chaleur haute température connecté au compresseur ; un condenseur connecté à l'échangeur de chaleur haute température ; une vanne de détente connectée au condenseur ; un tuyau de fluide frigorigène connecté respectivement à la vanne de détente d'un côté et au compresseur de l'autre côté ; un évaporateur adapté pour amener un fluide frigorigène dilaté à s'évaporer dans la vanne de détente par échange de chaleur avec un milieu chauffant, et pour acheminer le fluide frigorigène évaporé jusqu'au compresseur ; une unité externe comprenant un échangeur de chaleur externe dans lequel circule le milieu chauffant ; un dispositif de conditionnement d'air comprenant un ventilateur et un échangeur de chaleur interne dans lequel circule un milieu chauffant ; et un tuyau de milieu chauffant adapté pour contrôler le sens de circulation du milieu chauffant dans les modes de chauffage et de refroidissement.
