<p>A refrigerating plant, wherein a second refrigerant heat exchanger (5B) is connected to a liquid pipe (36a) and a suction side gas pipe (36b) of a second refrigerating circuit (2) through communication pipes (41, 42), respectively, using a first refrigerating circuit (1) for a refrigerating equipment (6) which is formed in a binary refrigerating cycle by connecting a hot refrigerating circuit (3) to a cold refrigerating circuit (4) through a first refrigerant heat exchanger (5A), a second refrigerating circuit (2) formed in a refrigerating cycle different from that of the first refrigerating circuit (1), and the second refrigerant heat exchanger (5B) connected to the cold refrigerant circuit (4), and first switching means (43, 44) are provided to selectively distribute the refrigerant in the second refrigerant circuit (2) to the second refrigerant heat exchanger (5B) through the communication pipes (41, 42), whereby the refrigerating operation can be continued even if a heat source device (11) stops in the refrigerating device operating on binary refrigerating cycle used in a show case.</p> |
