Title
(DE) WÄRMEPUMPE ZUR WARMWASSERBEREITUNG
(EN) HEAT PUMP FOR HEATING WATER
(FR) POMPE À CHALEUR DESTINÉE À FOURNIR DE L'EAU CHAUDE
Abstract
(DE)
Die Wärmepumpe dient zur Warmwasserbereitung, insbesondere zur Rückgewinnung von Wärme aus einem vorzugsweise in einer Küche anfallenden Abwasser, wobei die Wärmepumpe aus einem Verdichter für ein Kältemittel, einem Kondensator (1), einem Verdampfer (2) sowie einem zwischen Kondensator (1) und Verdampfer (2) angeordneten Expansionsventil besteht. Der Kondensator (1) steht mit dem Frischwasserzulauf (3) und der Verdampfer (2) mit dem Abwasserablauf (4) in thermischer Verbindung. Für den Frischwasserzulauf (3) und den Abwasserablauf (4) sind getrennte Wärmespeicher (5, 6) vorgesehen, die als Wärmetauscher ausgebildet sind. Dabei ist der Wärmespeicher (5) für den Frischwasserzulauf (3) von einem Latentwärmespeicher mit einem Phasenwechselmaterial (PCM-Material) gebildet.
(EN)
The heat pump serves for heating water, in particular for recovering heat from waste water produced preferably in a kitchen, wherein the heat pump consists of a compressor for a refrigerant, of a condenser (1), of an evaporator (2) and of an expansion valve arranged between the condenser (1) and evaporator (2). The condenser (1) is in thermal connection with the fresh-water supply (3) and the evaporator (2) is in thermal connection with the waste-water drainage (4). Separate heat accumulators (5, 6), designed as heat exchangers, are provided for the fresh-water supply (3) and the waste-water drainage (4). The heat accumulator (5) for the fresh-water supply (3) here is formed by a latent heat accumulator with a phase change material (PCM).

Pompe à chaleur servant à fournir de l'eau chaude, notamment à récupérer la chaleur des eaux usées, de préférence produites dans une cuisine, ladite pompe à chaleur étant constituée d'un compresseur pour un fluide frigorigène, d'un condenseur (1), d'un évaporateur (2) ainsi que d'une soupape de détente disposée entre le condenseur (1) et l'évaporateur (2). Le condenseur (1) est en communication thermique avec l'arrivée d'eau fraîche (3), et l'évaporateur (2) avec l'évacuation des eaux usées (4). Des accumulateurs de chaleur (5, 6) séparés sont prévus pour l'arrivée d'eau fraîche (3) et l'évacuation des eaux usées (4), lesquels sont réalisés sous forme d'échangeurs de chaleur. Selon l'invention, l'accumulateur de chaleur (5) pour l'arrivée d'eau fraîche (3) est un accumulateur de chaleur latente en matériau à changement de phase (MCP).
