Title (EN) REFRIGERATION CYCLE DEVICE
(FR) DISPOSITIF À CYCLE FRIGORIFIQUE
(JA) 冷凍サイクル装置
Abstract:
(EN) A refrigeration cycle device (10) configured so as to have a compressor (11), a high-temperature-side water-refrigerant heat exchanger (12), a branch unit (14a), an expansion valve (15a) for cooling, an expansion valve (15b) for heat absorption, an indoor evaporator (16), and an outdoor evaporator (18). The expansion valve (15a) for cooling and the indoor evaporator (16) are connected to one refrigerant outlet of the branch unit (14a), and the expansion valve (15b) for heat absorption and the outdoor evaporator (18) are connected to the other refrigerant outlet of the branch unit. In a cooling mode the device is switched to a refrigerant circuit in which refrigerant that has been decompressed in the expansion valve (15a) for cooling is made to exchange heat with blown air in the indoor evaporator (16), and in a heating mode the device is switched to a refrigerant circuit in which refrigerant that has been decompressed in the expansion valve (15b) for heat absorption is made to exchange heat in the outdoor evaporator (18), thereby absorbing heat from outside air and heating the blown air.
(FR) L'invention concerne un dispositif à cycle frigorifique (10) conçu pour comporter un compresseur (11), un échangeur de chaleur eau-fluide frigorigène (12) côté haute température, une unité de branchement (14a), un détendeur (15a) destiné au refroidissement, un détendeur (15b) destiné à l'absorption de chaleur, un évaporateur intérieur (16) et un évaporateur extérieur (18). Le détendeur (15a) destiné au refroidissement et l'évaporateur intérieur (16) sont reliées à une sortie de fluide frigorigène de l'unité de branchement (14a), et le détendeur (15b) destiné à l'absorption de chaleur et l'évaporateur extérieur (18) sont reliées à l'autre sortie de fluide frigorigène de l'unité de branchement. En mode de refroidissement, le dispositif est commuté vers un circuit de fluide frigorigène dans lequel le fluide frigorigène, détendu dans le détendeur (15a) destiné au refroidissement, est amené à échanger de la chaleur avec de l'air soufflé dans l'évaporateur intérieur (16), et, en mode de chauffage, le dispositif est commuté vers un circuit de fluide frigorigène dans lequel le fluide frigorigène, détendu dans le détendeur (15b) destiné à l'absorption de chaleur, est amené à échanger de la chaleur dans l'évaporateur extérieur (18), ce qui permet d'absorber la chaleur de l'air extérieur et de chauffer l'air soufflé.
(JA) 冷凍サイクル装置(10)は、圧縮機(11)と、高温側水-冷媒熱交換器(12)と、分岐部(14a)と、冷却用膨張弁(15a)と、吸熱用膨張弁(15b)と、室内蒸発器(16)と、室外蒸発器(18)とを有して構成されている。分岐部(14a)の一方の冷媒流出口には、冷却用膨張弁(15a)及び室内蒸発器(16)が接続されており、他方の冷媒流出口には、吸熱用膨張弁(15b)及び室外蒸発器(18)が接続されている。冷房モードでは、冷却用膨張弁(15a)で減圧された冷媒を室内蒸発器(16)にて送風空気と熱交換させる冷媒回路に切り替えられ、暖房モードでは、吸熱用膨張弁(15b)で減圧された冷媒を室外蒸発器(18)で熱交換させることで、外気から吸熱して送風空気を加熱する冷媒回路に切り替えられる。
