    • An object of the present invention is to keep an appropriate amount of a refrigerant to be circulated through a refrigerant circuit and prevent an overload operation of compression means due to high pressure abnormality in a refrigerating apparatus which obtains a supercritical pressure on a high pressure side. The refrigerating apparatus which obtains the supercritical pressure on the high pressure side comprises a refrigerant amount regulation tank connected to the refrigerant circuit on the high pressure side via a communicating circuit; a communicating circuit which connects the upper part of this tank to a medium pressure region of the refrigerant circuit; a communicating circuit which connects the lower part of the tank to the medium pressure region of the refrigerant circuit; an electromotive expansion valve of the communicating circuit; an electromagnetic valve of the communicating circuit; an electromagnetic valve of the communicating circuit; and control means for controlling these valves to collect a refrigerant circulated through the refrigerant circuit in the tank and discharging the refrigerant to the refrigerant circuit.
    • 本发明的目的在于,通过制冷剂回路保持合适量的制冷剂循环,防止在高压侧获得超临界压力的制冷装置中由于高压异常引起的压缩装置的过载运转。 获得高压侧的超临界压力的制冷装置包括通过连通回路与高压侧的制冷剂回路连接的制冷剂量调节槽; 连接该容器的上部与制冷剂回路的中压区域的连通回路; 一个连通电路,其连接箱的下部与制冷剂回路的介质压力区; 连通电路的电动膨胀阀; 所述通信电路的电磁阀; 所述通信电路的电磁阀; 以及控制装置,用于控制这些阀以收集循环通过储罐中的制冷剂回路的制冷剂并将制冷剂排放到制冷剂回路。

    • A management method and management apparatus that can prevent deterioration of response performance of an entire system is suggested.A management method and apparatus for managing a storage apparatus to which a hierarchical pool configuration technique is applied is designed to: select a migration-candidate virtual volume(s) from among virtual volumes to which a page(s) is allocated from a pool constituted from a storage tier(s) whose number of accesses per unit time has reached a performance threshold and whose used capacity has not reached a capacity threshold; select a pool(s) from which a page(s) is allocated to the virtual volume, as a migration source pool; also select a pool(s) constituted from a storage tier whose number of accesses per unit time has not reached the performance threshold, as a migration destination pool; decide a migration candidate pair(s) by combining the migration-candidate virtual volume(s) with the migration destination pool(s); calculate response performance of the entire system before and after migration respectively; and decide a migration candidate pair which is a migration object, based on the calculation result.
    • 建议可以防止整个系统的响应性能恶化的管理方法和管理装置。 用于管理应用分级池配置技术的存储设备的管理方法和装置被设计为:从构成的池的分配了一个页面的虚拟卷中选择一个或多个迁移候选虚拟卷 从每单位时间的访问次数达到性能阈值并且其使用容量未达到容量阈值的存储层; 选择一个从其分配页面的虚拟卷的池作为迁移源池; 还选择由每单位时间的访问次数尚未达到性能阈值的存储层构成的池作为迁移目的地池; 通过将迁移候选虚拟卷与迁移目的地池组合来确定迁移候选对; 分别计算迁移前后整个系统的响应性能; 并且基于计算结果来确定作为迁移对象的迁移候选对。
