(FR) PROCÉDÉ DE DÉTECTION DE QUANTITÉ DE FUITE DE GAZ ET PROCÉDÉ DE FONCTIONNEMENT D'APPAREIL DE RÉFRIGÉRATION
(JA) ガス漏れ量検知方法及び冷凍装置の運転方法
Abstract:
(EN) In this refrigerant circuit 12 using a non-azeotropic refrigerant, a gas leak amount is detected on the basis of a liquid temperature and a liquid pressure of a saturated liquid of said non-azeotropic refrigerant.
(FR) Dans ce circuit de réfrigérant (12) utilisant un réfrigérant non azéotrope, une quantité de fuite de gaz est détectée sur la base d'une température de liquide et d'une pression de liquide d'un liquide saturé dudit réfrigérant non azéotrope.
(JA) 非共沸冷媒を用いた冷媒回路12において、当該非共沸冷媒の飽和液の液温及び液圧に基づいてガス漏れ量を検知する。
