    • A refrigeration circuit (1a) comprises in the direction of flow of a circulating refrigerant a compressor unit (2) for compressing the refrigerant, a condenser (4), and at least one evaporator (10) having an expansion device (6) connected upstream thereof. The refrigeration circuit (1a) further comprises a subcooling temperature sensor (6) located at an outlet of the condenser (4) for measuring the temperature of refrigerant leaving the condenser (4), a control unit (12) functionally connected to the subcooling temperature sensor (6) and con¬ figured for detecting a leak in the refrigeration circuit (1a) based on the refrigerant temperature measured by the subcooling temperature sensor (6). The con¬ denser (4) comprises a liquefying portion (4a) configured for at least partially liquefying the refrigerant and a subsequent subcooling portion (4b) configured for subcooling and storing liquefied refrigerant, and the outlet of the condenser (4), particularly the outlet of the subcooling portion (4b), is connected to the expansion device (8) of the at least one evaporator (10) through a receiver-free connection line (7).
    • 制冷回路(1a)在循环制冷剂的流动方向上包括用于压缩制冷剂的压缩机单元(2),冷凝器(4)和至少一个具有连接到上游的膨胀装置(6)的蒸发器(10) 它们。 制冷回路(1a)还包括位于冷凝器(4)出口处的过冷温度传感器(6),用于测量离开冷凝器(4)的制冷剂的温度;控制单元(12)功能上连接到过冷却温度 传感器(6),并且被配置为基于由过冷温度传感器(6)测量的制冷剂温度来检测制冷回路(1a)中的泄漏。 冷凝器(4)包括构造成用于至少部分地液化制冷剂的液化部分(4a)和用于过冷和储存液化制冷剂的后续过冷部分(4b),以及冷凝器(4)的出口,特别是 过冷却部分(4b)的出口通过无接收器连接线(7)连接到至少一个蒸发器(10)的膨胀装置(8)。
