Title (EN) RECIRCULATING FLUID HEATING SYSTEMS
(FR) SYSTÈMES DE CHAUFFAGE DE FLUIDE DE RECIRCULATION
Abstract:
(EN) A liquid heating system includes an instantaneous heater (18) having an inlet (20) connected to a reservoir (62). The outlet (22) of the heater is connected to fixtures (72) which use the heated liquid, and is also connected through a return connection (30) to the reservoir. In an idle mode, a pump (40) draws liquid from the reservoir (62), so that the liquid circulates through the heater and back to the reservoir. A controller (52) actuates the heater to heat the liquid to a first setpoint temperature, so that the liquid in the reservoir stabilizes at the first setpoint temperature. In a supply mode, some or all of the heated liquid flows from the outlet to the fixtures (72). Cold liquid is admitted from a supply (60) to the reservoir, and cold liquid desirably also is supplied to the heater inlet along with liquid from the reservoir, so that the heater inlet receives a combination of these. The controller controls the proportion of cold liquid to liquid from the reservoir in the combination, so as to maintain the heater at a setpoint heating rate while also maintaining the temperature of liquid discharged from the heater outlet at or near a setpoint temperature.
(FR) L'invention concerne un système de chauffage de liquide comprenant un réchauffeur instantané (18) comportant une entrée (20) raccordée à un réservoir (62). La sortie (22) du réchauffeur est raccordée à des appareils (72) qui font appel au liquide chauffé, et est également raccordée par l'intermédiaire d'un raccord de retour (30) au réservoir. Dans un mode de repos, une pompe (40) extrait du liquide du réservoir (62), de sorte que le liquide circule à travers le réchauffeur et revienne vers le réservoir. Un dispositif de commande (52) actionne le réchauffeur pour qu'il chauffe le liquide à une première température de consigne, de sorte que le liquide contenu dans le réservoir se stabilise à la première température de consigne. Dans un mode d'alimentation, la totalité ou une partie du liquide chauffé s'écoule de la sortie vers les appareils (72). Du liquide froid est admis à partir d'une alimentation (60) vers le réservoir, et, de préférence, du liquide froid est également fourni à l'entrée de réchauffeur conjointement avec le liquide provenant du réservoir, de sorte que l'entrée de réchauffeur reçoive une combinaison de ces derniers. Le dispositif de commande commande la proportion de liquide froid par rapport au liquide provenant du réservoir dans la combinaison, de façon à maintenir le réchauffeur à une vitesse de chauffe de consigne tout en maintenant également la température de liquide déchargé de la sortie de réchauffeur à une température de consigne ou à une température proche de celle-ci.
