Abstract
(EN)
An air-conditioner (300) is provided with: a compressor (1); a passage switching valve (2); an outdoor heat exchanger (3); a passage guiding device (5); an expansion valve (6); and an indoor heat exchanger (7). The outdoor heat exchanger (3) includes a first heat-exchanging part (3a), and a second heat-exchanging part (3b). The passage guiding device (5) is configured to guide flowing of a refrigerant so as to supply the refrigerant which has flown in from the indoor heat exchanger (7) to the second heat-exchanging part (3b), and supply the refrigerant which has flown in from the expansion valve (6) via the second heat-exchanging part (3b) to the first heat-exchanging part (3a) during a heating operation, and so as to supply the refrigerant which has flown in from the first heat-exchanging part (3a) to the second heat-exchanging part (3b), and supply the refrigerant which has flown in from the expansion valve (6) via the second heat-exchanging part (3b) to the indoor heat exchanger (7) during a cooling operation.

L'invention concerne un climatiseur (300) étant pourvu : d'un compresseur (1) ; d'une valve de commutation de passage (2) ; d'un échangeur de chaleur extérieur (3) ; d'un dispositif de guidage de passage (5) ; d'un détendeur (6) ; et d'un échangeur de chaleur intérieur (7). L'échangeur de chaleur extérieur (3) comprend une première partie d'échange de chaleur (3a) et une seconde partie d'échange de chaleur (3b). Le dispositif de guidage de passage (5) est configuré pour guider l'écoulement d'un fluide frigorigène de façon à fournir le fluide frigorigène qui s'est écoulé depuis l'échangeur de chaleur intérieur (7) jusqu'à la seconde partie d'échange de chaleur (3b), et fournir le fluide frigorigène qui s'est écoulé depuis le détendeur (6) par l'intermédiaire de la seconde partie d'échange de chaleur (3b) vers la première partie d'échange de chaleur (3a) pendant une opération de chauffage, et de façon à fournir le fluide frigorigène qui s'est écoulé depuis la première partie d'échange de chaleur (3a) vers la seconde partie d'échange de chaleur (3b), et fournir le fluide frigorigène qui s'est écoulé depuis le détendeur (6) par l'intermédiaire de la seconde partie d'échange de chaleur (3b) vers l'échangeur de chaleur intérieur (7) pendant une opération de refroidissement.
