Abstract:
(EN) A usage-side unit (12) has a usage-side heat exchanger (51) and an expansion valve circuit unit (52). The expansion valve circuit unit (52) has: a temperature-sensitive usage-side expansion valve (53); a main pipe (60) for channeling a refrigerant between the usage-side heat exchanger (51) and a liquid-side connection pipe (13) via the usage-side expansion valve (53); a bypass pipe (70) for channeling a refrigerant between the usage-side heat exchanger (51) and the liquid-side connection pipe (13) so as to bypass the main pipe (60); and a switching mechanism (54) for switching the opening/closing of the main pipe (60) and the opening/closing of the bypass pipe (70).
(FR) Une unité côté utilisation (12) comporte un échangeur de chaleur (51) côté utilisation et une unité circuit de détendeur (52). L'unité circuit de détendeur (52) comporte : un détendeur (53) côté utilisation sensible à la température; un tuyau principal (60) pour acheminer un fluide frigorigène entre l'échangeur de chaleur (51) côté utilisation et un tuyau de raccordement (13) côté liquide par l'intermédiaire du détendeur (53) côté utilisation; un tuyau de dérivation (70) pour acheminer un fluide frigorigène entre l'échangeur de chaleur (51) côté utilisation et le tuyau de raccordement (13) côté liquide de façon à contourner le tuyau principal (60); et un mécanisme de commutation (54) pour commuter l'ouverture/fermeture du tuyau principal (60) et l'ouverture/fermeture du tuyau de dérivation (70).
(JA) 利用側ユニット(12)は、利用側熱交換器(51)と膨張弁回路部(52)を有している。膨張弁回路部(52)は、感温式の利用側膨張弁(53)と、利用側膨張弁(53)を経由して利用側熱交換器(51)と液側連絡配管(13)との間に冷媒を流すための主配管(60)と、主配管(60)を迂回して利用側熱交換器(51)と液側連絡配管(13)との間に冷媒を流すためのバイパス配管(70)と、主配管(60)の開閉およびバイパス配管(70)の開閉を切り換える切換機構(54)とを有している。
