Title
(EN) IMPROVED HEAT PUMP WATER HEATER
(FR) CHAUFFE-EAU AMELIORE A POMPE A CHALEUR
Abstract
(EN) A heat exchanger for a water heater of the type including a water tank having an inlet for water to be heated and an outlet for discharging heated water. The heat exchanger comprises a housing which receives and retains therein a coil in fluid communication with a heat pump circuit which circulates a heat exchange fluid provided form the heat pump circuit. The heat exchanger is disposed inside the tank such that water to be heated is disposed around the housing. Heat generated in the housing is imparted to the water via a wall of the housing, through thermal contact between the coil and the housing.
(FR) L'invention concerne un échangeur de chaleur destiné à un chauffe-eau du type comprenant un réservoir d'eau muni d'une entrée destinée à l'eau à chauffer et d'une sortie permettant d'évacuer l'eau chauffée. Cet échangeur de chaleur comprend un boîtier destiné à recevoir et retenir un serpentin se trouvant en communication fluidique avec un circuit de pompe à chaleur et permettant de faire circuler un fluide d'échange de chaleur en provenance de ce circuit de pompe à chaleur. Ledit échangeur de chaleur est disposé à l'intérieur du réservoir de façon que l'eau à chauffer entoure le boîtier. La chaleur générée dans le boîtier est transmise à l'eau par l'intermédiaire d'une paroi du boîtier, et notamment par contact thermique entre le serpentin et le boîtier.
