    • A coil wound heat exchanger has a shell enclosing a shell space. A tubing assembly is configured inside the shell space, and a refrigerant distributor is arranged inside the shell space gravitationally above the tubing assembly, for allowing a downward stream of liquid refrigerant inside the shell space. A liquid drain line is connected to the shell at a gravitational low level, for draining non-evaporated liquid refrigerant from the shell space. A vapour chamber is arranged inside the shell space, with a vapour chamber inlet. A vapour discharge line is in fluid communication with the shell space of the coil wound heat exchanger for discharging evaporated refrigerant from the shell space. The vapour discharge line and the vapour chamber inlet are separated from each other by gas/liquid separator internals. The gas/liquid separator internals prevent any liquid constituents from entering the vapour discharge line from the shell space.
    • 缠绕的线圈热交换器具有外壳包围壳的空间。 管组件被配置为在外壳内部空间,和一个制冷剂分配器布置重力上面的管组件的外壳空间内,用于允许所述壳空间内的液体制冷剂的向下料流。 一种液体排放管线连接到所述壳在重力低电平,用于从所述外壳空间排出未蒸发的液体制冷剂。 蒸汽室设置在所述外壳内部空间,具有蒸气室入口。 蒸气排出管线是与线圈缠绕的热交换器,用于从壳空间排出蒸发的制冷剂的壳空间流体连通。 蒸气排出管线和蒸气室入口彼此通过气体/液体分离器的内部分隔。 气体/液体分离器的内部防止任何液体组分从外壳空间进入汽放线。
