冷却系统
摘要：
本发明公开了一种冷却系统，包括制冷回路(1)，其使制冷剂循环，且在所述制冷剂的流动方向上包括：至少一个压缩机(2a、2b、2c、2d)；至少一个冷凝器(4)；至少一个膨胀装置(8、10)；以及用于提供冷却能力的至少一个蒸发器(11)。冷却系统还包括用于使在制冷回路(1)中循环的制冷剂过冷的过冷回路(20)，过冷回路(20)构造成使过冷制冷剂循环，且包括至少一个过冷器压缩机(22、23)；至少一个热交换器件(6、7)，其布置在至少一个冷凝器(4)的下游，且构造成在制冷回路(1)与过冷回路(20)之间热交换，至少一个热交换器件(6、7)包括至少一个温度传感器；以及控制单元(15)，其构造成用于控制制冷回路(1)的至少一个压缩机(2a、2b、2c、2d)和过冷回路(20)的至少一个过冷器压缩机(22、23)，使得待由至少一个蒸发器(11)提供的冷却能力被满足，且使得由至少一个温度传感器测量的至少一个热交换器件(6、7)处的温度处于预定范围。
摘要（英）：

A cooling system comprises a refrigeration circuit (1) circulating a refrigerant and comprising in the flow direction of the refrigerant at least one compressor (2a, 2b, 2c, 2d); at least one condenser (4); at least one expansion device (8, 10); and at least one evaporator (11) for providing a cooling capacity. The cooling system further comprises a subcooling circuit (20) for subcooling the refrigerant circulating in the refrigeration circuit (1), the subcooling circuit (20) being configured to circulate a subcooling refrigerant and comprising at least one subcooler compressor (22, 23); at least one heat exchange means (6, 7) being arranged downstream of the at least one condenser (4) and being configured for heat exchange between the refrigeration circuit (1) and the subcooling circuit (20), the at least one heat exchange means (6, 7) comprising at least one temperature sensor; and a control unit (15) which is configured for controlling at least one compressor (2a, 2b, 2c, 2d) of the refrigeration circuit (1) and at least one subcooler compressor (22, 23) of the subcooling circuit (20) such that the cooling capacity to be provided by the at least one evaporator (11) is met and such that the temperature at the at least one heat exchange means (6, 7) measured by at least one temperature sensor is in a predetermined range.
