The invention relates to a refrigeration device (10) with heat pump function for a motor vehicle, comprising: a refrigerant compressor (12) which is or can be connected to a primary branch (14); an external heat exchanger (18) which acts directly or indirectly and is arranged in the primary branch (14); a first evaporator (22) arranged in the primary branch (14); a first heat exchanger acting directly or indirectly, in particular a chiller (28), which is arranged in parallel with the evaporator (22) in terms of flow technology; and a refrigerant collector (24) arranged on the low pressure side. According to the invention, a single sensor device (pT2) is arranged downstream of the evaporator (22) and the further heat exchanger, in particular the chiller (28), said sensor device being designed to detect the pressure and temperature of the refrigerant on the low-pressure side of the refrigeration device (10). The invention also relates to a motor vehicle having such a refrigeration device.
本发明涉及一种用于的机动车具有热泵功能的制冷设备(10),制冷设备(10)包括:制冷剂压缩机(12),其与初级支路(14)连接或可与之连接;直接或间接作用的外部热交换器(18),其布置在初级支路(14)中;第一蒸发器(22),其布置在初级支路(14)中;直接或间接作用的第一热交换器、尤其是深冷器(28),其在流动技术方面与蒸发器(22)并联布置;以及布置在低压侧的制冷剂收集器(24)。在此规定,在蒸发器(22)和另一热交换器、尤其是深冷器(28)下游布置有唯一的传感器装置(pT2),传感器装置被设置成检测制冷设备(10)的低压侧上的制冷剂的压力和温度。本发明还涉及具有这种制冷设备的机动车。
