    • The invention relates to a device for cooling a vehicle interior with a secondary circuit (26) for transferring the cold produced in an evaporator (24) of a primary refrigerating circuit (14) of a refrigerating unit (12) by means of a refrigerating medium to at least one heat transfer device (34) for cooling the air to be fed into the vehicle interior, the secondary circuit (26) having a main circuit (36) and an auxiliary circuit (40) containing the heat transfer device (34), which are coupled by a four-way valve (56), by means of which an adjustable proportion of the flow of refrigerating medium can be diverted from the main circuit (36) and fed into the auxiliary circuit (40). In order to provide an improved device for cooling, in particular one that can be produced at a more reasonable cost, it is proposed that an inner heat exchanger (80) should be provided in the auxiliary circuit (40), allowing heat exchange to take place between a feed (60) and a return (62). This makes it possible to dispense with the use of a circulation pump in the auxiliary circuit.
    • 本发明涉及一种用于冷却具有二次回路(26)的车辆内部的装置,用于通过制冷介质传递在制冷单元(12)的主要制冷回路(14)的蒸发器(24)中产生的冷 至少一个用于冷却要供给到车辆内部的空气的传热装置(34),所述次级回路(26)具有主回路(36)和包含传热装置(34)的辅助回路(40) ,其通过四通阀(56)联接,通过该四通阀(56)可以将冷冻介质流的可调节比例从主回路(36)转向并进给辅助回路(40)。 为了提供一种改进的冷却装置,特别是可以以更合理的成本生产的装置,建议在辅助回路(40)中设置内部热交换器(80),从而允许热交换 放置在进料(60)和回油(62)之间。 这使得可以省略在辅助回路中使用循环泵。
