Abstract:
(EN) An air conditioning device (301) is provided with a flow path switching valve (202). An outdoor heat exchanger (40) is divided into a first heat exchanger (40A) and a second heat exchanger (40B). A refrigerant supplied from an expansion valve (30) during a heating operation is divided into two flows and supplied to the first heat exchanger (40A) and the second heat exchanger (40B). The flow path switching valve (202) converges the refrigerant discharged from the first heat exchanger (40A) and the second heat exchanger (40B) and returns said refrigerant to a refrigerant inlet of a compressor (10) during the heating operation. A valve body (203) of the flow path switching valve (202) is configured so that during the heating operation, three ports (B1, B2, B3) communicate internally in a state of being isolated from another one port (A). The valve body (203) is configured so that during an operation to defrost the first heat exchanger (40A) or second heat exchanger (40B), two ports (A, B1 or A, B2) communicate internally and the other two ports (B2, C or B1, C) communicate internally.
(FR) Dispositif de climatisation (301) pourvu d'un clapet de commutation (202) de voie d'écoulement. Un échangeur de chaleur extérieur (40) est séparé en un premier échangeur de chaleur (40A) et en un second échangeur de chaleur (40B). Un fluide frigorigène apporté depuis un détendeur (30) pendant une opération de chauffage est séparé en deux flux et apporté au premier échangeur de chaleur (40A) et au second échangeur de chaleur (40B). Le clapet de commutation (202) de voie d'écoulement fait converger le fluide frigorigène rejeté du premier échangeur de chaleur (40A) et du second échangeur de chaleur (40B) et renvoie ledit fluide frigorigène à une entrée de fluide frigorigène d'un compresseur (10) pendant l'opération de chauffage. Un corps (203) de clapet du clapet de commutation (202) de voie d'écoulement est conçu de telle sorte que, pendant l'opération de chauffage, trois orifices (B1, B2, B3) communiquent intérieurement dans un état isolé d'un autre orifice (A). Le corps (203) de clapet est conçu de telle sorte que, pendant une opération pour dégivrer le premier échangeur de chaleur (40A) ou le second échangeur de chaleur (40B), deux orifices (A, B1, ou A, B2) communiquent intérieurement, et les deux autres orifices (B2, C ou B1, C) communiquent intérieurement.
(JA) 空気調和装置(301)は、流路切替弁(202)を備える。室外熱交換器(40)は、第1熱交換器(40A)および第2熱交換器(40B)に分割されている。暖房運転時に膨張弁(30)から供給される冷媒は、第1熱交換器(40A)および第2熱交換器(40B)に分流されて供給される。流路切替弁(202)は、暖房運転時に、第1熱交換器(40A)および第2熱交換器(40B)から排出される冷媒を合流させ、圧縮機(10)の冷媒入口に戻す。流路切替弁(202)の弁本体(203)は、暖房運転時には3ポート(B1,B2,C)が他の1ポート(A)とは分離された状態で内部で連通するように構成される。弁本体(203)は、第1熱交換器(40A)または第2熱交換器(40B)の除霜運転時には2ポート(A,B1またはA,B2)が内部で連通するとともに、他の2ポート(B2,CまたはB1,C)が内部で連通するように構成される。
