Title
(EN) HEAT PUMP HOT WATER SUPPLY DEVICE
(FR) DISPOSITIF D’ALIMENTATION EN EAU CHAUDE D’UNE POMPE A CHALEUR
(JA) ヒートポンプ式給湯機
Abstract
(EN) A heat pump hot water supply device where a heat pump cycle for hot water supply can be used for cooling and heating (air conditioning) and in which sufficient temperature and quantity of hot water supply are obtained when hot water is provided along with heating. The hot water supply device has a CO2 cycle (1) where CO2 refrigerant is circulated and also has an R410A cycle (2) where R410A refrigerant is circulated; a water heat exchanger (32) for performing heat exchange between water and the CO2 refrigerant and/or the R410A refrigerant. The R410A cycle (2) has a circulation route (20) passing through the water heat exchanger (32), a circulation route (40) passing through an indoor-air heat exchanger (4) for exchanging heat between the R410A refrigerant and indoor air, and a four-way valve (24) for changing the direction of circulation of the R410A refrigerant in the R410A cycle (2).
(FR) La présente invention concerne un dispositif d’alimentation en eau chaude d’une pompe à chaleur dans lequel un cycle de pompe à chaleur destiné à l’alimentation en eau chaude peut être utilisé pour refroidir et chauffer (climatiseur) et dans lequel on obtient une température et une quantité suffisantes d’eau chaude lorsque l’on délivre de l’eau chaude en même temps que le chauffage. Le dispositif d’alimentation en eau chaude possède un cycle CO2 (1) dans lequel circule un réfrigérant CO2 ainsi qu’un cycle R410A (2) dans lequel circule un réfrigérant R410A ; un échangeur de chaleur d’eau (32) destiné à effectuer un échange de chaleur entre l’eau et le réfrigérant CO2 et/ou le réfrigérant R410A. Le cycle R410A (2) possède un trajet de circulation (20) passant par l’échangeur de chaleur d’eau (32), un trajet de circulation (40) passant par un échangeur de chaleur d’air intérieur (4) destiné à échanger la chaleur entre le réfrigérant R410A et de l’air intérieur, et une vanne à quatre voies (24) destinée à modifier le sens de la circulation du réfrigérant R410A dans le cycle R410A (2).
(JA) 給湯用のヒートポンプサイクルを冷暖房(空調)に用いることのできるヒートポンプ式給湯機を提供すること。また,前記ヒートポンプ式給湯機において暖房と同時に給湯を行う際に十分な給湯温度や給湯量を得ること。  CO2冷媒が循環されるCO2サイクル1と,R410A冷媒が循環されるR410Aサイクル2と,前記CO2冷媒及び/又は前記R410A冷媒と水との間で熱交換を行う水熱交換器32と,を備えてなり,前記R410Aサイクル2に,前記水熱交換器32を通過する循環経路20と,前記R410A冷媒と室内空気との間で熱交換を行う室内空気熱交換器4を通過する循環経路40と,当該R410Aサイクル2における前記R410A冷媒の循環方向を切り替える四方弁24とが設けられている。
