Title (EN) HEAT EXCHANGER AND VALVE DEVICE
(FR) ÉCHANGEUR DE CHALEUR ET DISPOSITIF DE SOUPAPE
(JA) 熱交換器、弁装置
Abstract:
(EN) This heat exchanger (16) is applied to a heat pump cycle (10) which can be switched between a cooling mode in which a fluid to be temperature-controlled is cooled by switching the circulation path of a refrigerant including an oil, and a heating mode in which the fluid to be temperature-controlled is heated. An outdoor heat exchanger is provided with: a core part (17) which condenses the refrigerant during the cooling mode and evaporates the refrigerant during the heating mode; and a liquid receiver (18) having a liquid storing part (184) which temporarily stores a portion of the refrigerant flowing out from the core part in the cooling mode as an excess refrigerant in the cycle. In addition, the outdoor heat exchanger is provided with a valve device (30) which switches the circulation path of the refrigerant in the cycle. The valve device is provided with an intake-side flow passage (306) which guides the refrigerant in the liquid storing part toward the refrigerant intake side of a compressor (12) of the heat pump cycle during the heating mode. In addition, the intake-side flow passage communicates with a lower section (184c) of the liquid storing part, the lower section (184c) being closer to a lower end section (184b) than to an upper end section (184a) of the liquid storing part.
(FR) Cet échangeur de chaleur (16) est appliqué à un cycle de pompe à chaleur (10) qui peut être commuté entre un mode de refroidissement dans lequel un fluide à réguler en température est refroidi par commutation du trajet de circulation d'un fluide frigorigène comprenant une huile, et un mode de chauffage dans lequel le fluide à réguler en température est chauffé. Un échangeur de chaleur extérieur comprend: une partie centrale (17) qui condense le fluide frigorigène pendant le mode de refroidissement et évapore le fluide frigorigène pendant le mode de chauffage; et un récepteur de liquide (18) ayant une partie de stockage de liquide (184) qui stocke temporairement une partie du fluide frigorigène s'écoulant hors de la partie centrale dans le mode de refroidissement en tant que fluide frigorigène en excès dans le cycle. De plus, l'échangeur de chaleur extérieur est pourvu d'un dispositif de soupape (30) qui commute le trajet de circulation du fluide frigorigène dans le cycle. Le dispositif de soupape est pourvu d'un passage d'écoulement côté admission (306) qui guide le fluide frigorigène dans la partie de stockage de liquide vers le côté d'admission de fluide frigorigène d'un compresseur (12) du cycle de pompe à chaleur pendant le mode de chauffage. De plus, le passage d'écoulement côté admission communique avec une section inférieure (184c) de la partie de stockage de liquide, la section inférieure (184c) étant plus proche d'une section d'extrémité inférieure (184b) qu'à une section d'extrémité supérieure (184a) de la partie de stockage de liquide.
(JA) 熱交換機(16)は、オイルを含む冷媒の循環経路を切り替えることで温調対象流体を冷却するための冷却モードと温調対象流体を加熱するための加熱モードとを切替可能なヒートポンプサイクル(10)に適用される。室外熱交換器は、冷却モード時に冷媒を凝縮させ、加熱モード時に冷媒を蒸発させるコア部(17)と、冷却モード時にコア部から流出した冷媒の一部をサイクル内の余剰冷媒として一時的に貯留する液溜め部(184)を有する受液器(18)と、を備える。また、室外熱交換器は、サイクル内の冷媒の循環経路を切り替える弁装置(30)を備える。弁装置には、加熱モード時に液溜め部の冷媒をヒートポンプサイクルの圧縮機(12)の冷媒吸入側に導く吸入側流路(306)が設けられている。そして、吸入側流路は、液溜め部のうち上端部(184a)よりも下端部(184b)に近い下方側部位(184c)に連通している。
