The invention relates to a method for operating a refrigerant circuit (10) of a motor vehicle, in which a compressor (16) arranged in a main line (14) of the refrigerant circuit (10) conveys at least a minimum mass flow of refrigerant. At least one parameter describing the refrigeration power of a first evaporator (20) arranged in the main line (14) is detected. The first evaporator (20) provides refrigeration power as a result of being loaded with a refrigeration medium expanded by means of the first expansion means (22). A second expansion mechanism (36) arranged in the parallel line (30) upstream of the second evaporator (38) arranged in the parallel line (30) can be opened as a function of the refrigeration power provided by the first evaporator (20) when the mass flow of the refrigeration medium is minimum. In addition or alternatively, at least one measure which is different from the opening of the second expansion mechanism (36) and causes an increase in the heat absorption of the refrigerant is taken depending on the refrigeration power of the first evaporator (20).

    本发明涉及一种用于运行机动车的制冷介质回路(10)的方法,在其中,布置在制冷介质回路(10)的主线(14)中的压缩机(16)输送至少最小质量流量的制冷介质。检测至少一个描述布置在主线(14)中的第一蒸发器(20)的制冷功率的参数。第一蒸发器(20)由于被借助于第一膨胀机构(22)膨胀的制冷介质加载而提供制冷功率。可以根据在制冷介质的质量流最小时第一蒸发器(20)提供的制冷功率,打开在并行线(30)中布置在第二、布置在并行线(30)中的蒸发器(38)上游的第二膨胀机构(36)。附加地或替代地,根据第一蒸发器(20)的制冷功率,采取至少一种与所述打开第二膨胀机构(36)不同的导致制冷介质的热吸收增加的措施。
