The invention relates to a method for operating a refrigeration circuit system of a vehicle, a refrigeration circuit system for carrying out the method and a vehicle having the refrigeration circuit system. The refrigeration circuit system (2) has a refrigerant circuit (4) in which a refrigerant circulates and which is divided into a high-pressure region (5) and a low-pressure region (6), the refrigeration circuit system (2) having a compressor (7) arranged in the refrigerant circuit (4) for compressing the refrigerant. According to the invention, pressure and temperature values (9) of the refrigerant in the low-pressure region (6) are measured by means of a pressure and temperature sensor (8) arranged in the low-pressure region (6), and then ascertaining a pressure value (10) of the refrigerant in the high-pressure region (5) on the basis of the measured pressure and temperature values (9) and the provided compressor overall characteristic curve of the compressor (7).
本发明涉及用于运行车辆的制冷回路系统的方法、用于实施该方法的制冷回路系统和具有该制冷回路系统的车辆。制冷回路系统(2)具有制冷剂回路(4),制冷剂在制冷剂回路中循环,并且制冷剂回路分为高压区域(5)和低压区域(6),其中,制冷回路系统(2)具有布置在制冷剂回路(4)中的用于压缩制冷剂的压缩机(7)。在该方法的范围内设置的是,借助布置在低压区域(6)内的压力和温度传感器(8)测量低压区域(6)内的制冷剂的压力值和温度值(9),并且然后借助所测得的压力值和温度值(9)以及所提供的压缩机(7)的压缩机综合特性曲线获知高压区域(5)内的制冷剂的压力值(10)。
