Abstract

Un dispositif de refroidissement/chauffage pour une patinoire est décrit. Le dispositif fournit de la chaleur froide générée par un circuit de thermopompe à la patinoire et de la chaleur chaude générée par le circuit de thermopompe aux installations de consommation de chaleur chaude annexées à la patinoire. Le dispositif comprend un moyen de condensation comportant des échangeurs de chaleur, ces derniers étant reliés au circuit de thermopompe en parallèle et chauffant de leau à basse température au moyen de la chaleur de condensation dun frigorigène à base de CO2; un robinet à trois voies prévu à un point de branchement du frigorigène à base de CO2 sur les côtés amont des échangeurs de chaleur dans le circuit de thermopompe; et un dispositif de commande qui commande louverture du robinet à trois voies en fonction de la température du frigorigène à la sortie des échangeurs de chaleur, de manière que le dispositif commande le débit du frigorigène introduit dans les échangeurs de chaleur.
