    • The invention provides a PCM cooling device (100), comprising:a cooling tank (10); a tube (11) filled with PCM material; an inlet unit (12), configured to introduce working fluid from a free cooling device (200) in a first working mode, and to introduce working fluid from a system to be cooled (400) in a second working mode; a distribution means (13), used to distribute the working fluid introduced from the inlet unit (12), bringing it in contact with the tube (11); an outlet unit (14), configured to discharge the working fluid having contacted with the tube (11) into the free cooling device (200) in the first working mode, and to discharge the working fluid having contacted with the tube (11) into the system to be cooled (400) in the second working mode. The invention further provides a cooling system (600) comprising the above PCM cooling device (100) and a free cooling device (200). The invention further provides a controlling method and a controlling unit (500) for controlling the above cooling system (600). By using the PCM cooling device (100) and the free cooling device (200) in combination, the energy consumption of the cooling system (600) may be decreased.
    • 本发明提供一种PCM冷却装置(100),包括:冷却罐(10); 填充有PCM材料的管(11); 入口单元(12),其构造成以第一工作模式从自由冷却装置(200)引入工作流体,并且以第二工作模式从待冷却系统(400)引入工作流体; 分配装置(13),用于分配从入口单元(12)引入的工作流体,使其与管(11)接触; 出口单元(14),其构造成在第一工作模式中将与管(11)接触的工作流体排放到自由冷却装置(200)中,并且将与管(11)接触的工作流体排放到 待冷却的系统(400)处于第二工作模式。 本发明还提供一种包括上述PCM冷却装置(100)和一个自由冷却装置(200)的冷却系统(600)。 本发明还提供一种用于控制上述冷却系统(600)的控制方法和控制单元(500)。 通过组合使用PCM冷却装置(100)和自由冷却装置(200),可以降低冷却系统(600)的能量消耗。
