Title (EN) HEAT PUMP UNIT AND THE CONTROL METHOD THEREOF
(FR) UNITÉ DE POMPE À CHALEUR ET SON PROCÉDÉ DE COMMANDE
Abstract:
(EN) A heat pump unit and methods for operating the heat pump unit are provided. The heat pump unit includes a compressor (101), a throttling device (107), a first heat exchanger (104), a second heat exchanger (102), a third heat exchanger (103) and a mid-pressure tank (110). The heat pump unit operates in multiple run modes and switches between the run modes without shutdown. The first heat exchanger or the second heat exchanger is capable of acting as a condenser in the multiple run modes. When switching from a pre- switching run mode to a post-switching run mode, a control device determines whether to perform a pressure release operation to the first heat exchanger or the second heat exchanger.
(FR) L'invention concerne une unité de pompe à chaleur et des procédés pour faire fonctionner l'unité de pompe à chaleur. L'unité de pompe à chaleur comprend un compresseur (101), un dispositif d'étranglement (107), un premier échangeur de chaleur (104), un deuxième échangeur de chaleur (102), un troisième échangeur de chaleur (103) et un réservoir sous moyenne pression (110). L'unité de pompe à chaleur fonctionne dans de multiples modes de fonctionnement et commute entre les modes de fonctionnement sans interruption. Le premier échangeur de chaleur ou le second échangeur de chaleur peut agir comme un condenseur dans les multiples modes de fonctionnement. Lors de la commutation d'un mode de fonctionnement de pré-commutation à un mode de fonctionnement de post-commutation, un dispositif de commande détermine s'il faut effectuer une opération de libération de pression sur le premier échangeur de chaleur ou le second échangeur de chaleur.
