Abstract: A connection system for carrying a refrigerant may provide a hybrid redundancy in sealing a refrigerant flow from the surround system environment. The connection system may include a first sealing ring of a first type and a second sealing ring of a second type positioned downstream from the first sealing ring. In some embodiments, the first sealing ring may be in a groove positioned around the outside diameter of a male fitting. The second sealing ring may be positioned at an interface between the male fitting and a female fitting. In some embodiments, flanges of each fitting define the interface so that the second sealing ring may be positioned between the flanges of each fitting. The second sealing ring may be selected from a material that has a wider range of operating temperature than the first sealing ring so that in the event of failure in the first sealing ring, the second sealing ring may prevent leakage.

Abstract translation: 用于承载制冷剂的连接系统可以提供混合冗余以密封来自环绕系统环境的制冷剂流。 连接系统可以包括位于第一密封环下游的第一类型的第一密封环和第二类型的第二密封环。 在一些实施例中，第一密封环可以位于围绕阳配件的外径定位的凹槽中。 第二密封环可以位于阳配件和阴配件之间的界面处。 在一些实施例中，每个配件的凸缘限定界面，使得第二密封环可以位于每个配件的凸缘之间。 第二密封环可以选自具有比第一密封环更宽的工作温度范围的材料，使得在第一密封环发生故障的情况下，第二密封环可以防止泄漏。
