Abstract
(EN) A hot-water supply device (10) has a first refrigerant circuit (20), a medium-temperature water circuit (40), a second refrigerant circuit (60), and a high-temperature water circuit (80). The first refrigerant circuit (20) forms a heat pump using outdoor air as the heat source and heats heat medium water in the medium-temperature water circuit (40). In the medium-temperature water circuit (40), the heat medium water circulates between a radiator (45) for floor heating, a second heat exchanger (50), and a first heat exchanger (30). The second refrigerant circuit (60) forms a heat pump using as the heat source the heat medium water in the medium-temperature water circuit (40) and heats water for hot water supply in the high-temperature water circuit (80).
(FR) Dispositif d’approvisionnement en eau chaude (10) comportant un premier circuit d’agent réfrigérant (20), un circuit d’eau à température moyenne (40), un second circuit d’agent réfrigérant (60), et un circuit d’eau à haute température (80). Le premier circuit d’agent réfrigérant (20) constitue une pompe à chaleur qui utilise l’air extérieur comme source de chaleur et chauffe l’eau servant au transfert de chaleur dans le circuit d’eau à température moyenne (40). Dans le circuit d’eau à température moyenne (40), l’eau servant au transfert de chaleur circule entre un radiateur (45) de chauffage par le sol, un second échangeur de chaleur (50) et un premier échangeur de chaleur (30). Le second circuit d’agent réfrigérant (60) forme une pompe à chaleur utilisant comme source de chaleur l’eau servant au transfert de chaleur dans le circuit d’eau à température moyenne (40) et chauffe l’eau pour l’approvisionnement en eau chaude dans le circuit d’eau haute température (80).
(JA)  給湯装置(10)には、第1冷媒回路(20)、中温水回路(40)、第2冷媒回路(60)、及び高温水回路(80)が設けられる。第1冷媒回路(20)は、室外空気を熱源としたヒートポンプを構成し、中温水回路(40)内の熱媒水を加熱する。中温水回路(40)では、床暖房用放熱器(45)や第2熱交換器(50)と第1熱交換器(30)との間で熱媒水が循環する。第2冷媒回路(60)は、中温水回路(40)の熱媒水を熱源としたヒートポンプを構成し、高温水回路(80)内の給湯用水を加熱する。
