Title (EN) HEAT PUMP CYCLE DEVICE AND VALVE DEVICE
(FR) DISPOSITIF À CYCLE DE POMPE À CHALEUR ET DISPOSITIF SOUPAPE
(JA) ヒートポンプサイクル装置および弁装置
Abstract:
(EN) This heat pump cycle device is provided with a flow passage switching part (30) which switches a refrigerant flow passage of a refrigerant circulation circuit. The flow passage switching part switches a flow passage between a cooling-side flow passage (105) which during a cooling mode guides the refrigerant flowing out from a heat exchanger to a compressor via a second decompressor and an evaporator, and a heating-side flow passage (104) which during a heating mode guides the refrigerant flowing out from the heat exchanger to the compressor while bypassing the second decompressor and the evaporator. The flow passage switching part has a flow passage switching valve body which opens/closes the cooling-side flow passage. The refrigerant circulation circuit includes: a low-pressure flow passage (106) through which a low-pressure refrigerant decompressed in a first decompressor flows toward the compressor during the heating mode; and a pre-evaporator flow passage (107) between the flow passage switching valve body and the refrigerant inlet of the evaporator. During the heating mode, when the pressure of the refrigerant in the low-pressure flow passage is lower than the pressure of the refrigerant in the pre-evaporator flow passage, the flow passage switching part makes the pre-evaporator flow passage communicate with the low-pressure flow passage while bypassing the evaporator.
(FR) L'invention concerne un dispositif à cycle de pompe à chaleur pourvu d'une partie de commutation de passage d'écoulement (30) qui commute un passage d'écoulement de fluide frigorigène d'un circuit de circulation de fluide frigorigène. La partie de commutation de passage d'écoulement commute un passage d'écoulement entre un passage d'écoulement côté refroidissement (105) qui, pendant un mode de refroidissement, guide le fluide frigorigène s'écoulant d'un échangeur de chaleur à un compresseur par l'intermédiaire d'un second décompresseur et d'un évaporateur, et un passage d'écoulement côté chauffage (104) qui, pendant un mode de chauffage, guide le fluide frigorigène s'écoulant de l'échangeur de chaleur vers le compresseur tout en contournant le second décompresseur et l'évaporateur. La partie de commutation de passage d'écoulement comporte un corps de soupape de commutation de passage d'écoulement qui ouvre/ferme le passage d'écoulement côté refroidissement. Le circuit de circulation de fluide frigorigène comprend : un passage d'écoulement basse pression (106) à travers lequel un fluide frigorigène basse pression décomprimé dans un premier décompresseur s'écoule vers le compresseur pendant le mode de chauffage ; et un passage d'écoulement de pré-évaporateur (107) entre le corps de soupape de commutation de passage d'écoulement et l'entrée de fluide frigorigène de l'évaporateur. Pendant le mode de chauffage, lorsque la pression du fluide frigorigène dans le passage d'écoulement basse pression est inférieure à la pression du fluide frigorigène dans le passage d'écoulement de pré-évaporateur, la partie de commutation de passage d'écoulement amène le passage d'écoulement de pré-évaporateur à communiquer avec le passage d'écoulement basse pression tout en contournant l'évaporateur.
(JA) ヒートポンプサイクル装置は、冷媒循環回路の冷媒流路を切り替える流路切替部(30)を備える。流路切替部は、冷却モード時に熱交換器から流出した冷媒を第2減圧器および蒸発器を経由して圧縮機に導く冷却側流路(105)と、加熱モード時に熱交換器から流出した冷媒を第2減圧器および蒸発器を迂回して圧縮機に導く加熱側流路(104)とを切り替える。流路切替部は、冷却側流路を開閉する流路切替弁体を有する。冷媒循環回路は、加熱モード時に第1減圧器で減圧された低圧冷媒が圧縮機に向かって流れる低圧流路(106)と、流路切替弁体と蒸発器の冷媒入口との間の蒸発器前流路(107)とを含む。加熱モード時に、低圧流路の冷媒圧力が蒸発器前流路の冷媒圧力よりも低いときに、流路切替部は、蒸発器を迂回して蒸発器前流路を低圧流路に連通させている。
