液化气体用冷却装置
摘要：
液化气体用冷却装置(1)具备：气体流路(2)，其供通过冷却而液化的液化气体流通；和制冷装置(3)，其由对在气体流路(2)内流动的液化气体进行冷却的蒸发器(7)、压缩机(4)、冷凝器(5)以及节流膨胀器(6)构成制冷循环系统(10)，制冷装置(3)具备：在压缩机(4)的吸入流路(9A)以及排出流路(9B)中分别设置的吸入侧开闭阀(21)以及排出侧开闭阀(22)；和在吸入侧开闭阀(21)与排出侧开闭阀(22)之间的制冷剂流路(9)中设置的维护用开闭阀(23)。
摘要（英）：

A cooling device for liquefied gas (1) is provided with: a gas passage (2) in which liquefied gas, which is liquefied via cooling, flows; and a refrigeration device (3) in which a refrigeration cycle (10) is formed by an evaporator (7), which cools the liquefied gas flowing in the gas passage (2), a compressor (4), a condenser (5), and a contraction/expansion apparatus (6). The refrigeration device (3) is provided with: an intake-side on-off valve (21) and a discharge-side on-off valve (22) respectively provided to an intake passage (9A) and a discharge passage (9B) of the compressor (4); and a service on-off valve (23) provided to a refrigerant passage (9) that is between the intake-side on-off valve (21) and the discharge-side on-off valve (22).
