The invention relates to a method for operating a refrigerant circuit (10) of a motor vehicle, comprising a compressor (16) which, in a heating operation of the refrigerant circuit (10), conveys refrigerant through a first condenser (18), by means of which an air flow (20) that can be introduced into a passenger compartment is heated. The compressor (16) delivers a refrigerant through the second condenser (28) for further cooling. At least one partial flow of the refrigerant from the second condenser (28) is expanded by means of a first expansion device (36) and fed to a first evaporator (38) by means of which the humidity of the air flow can be reduced. In order to increase the heating power available at the first condenser (18), a further partial flow of the refrigerant is expanded by means of a second expansion device (72) and fed to a second evaporator (64). The refrigerant from the evaporator (38, 64) is fed to the suction side (48) of the compressor (16). The invention further relates to a motor vehicle having a refrigerant circuit (10).

    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,制冷介质回路具有压缩机(16),在制冷介质回路(10)的加热运行中,压缩机输送制冷介质通过第一冷凝器(18),借助于第一冷凝器加热可引入乘客舱中的空气流(20)。压缩机(16)输送制冷介质通过第二冷凝器(28)以进一步冷却。来自第二冷凝器(28)的制冷介质的至少一个子流借助于第一膨胀装置(36)膨胀,并且被输送给第一蒸发器(38),借助于第一蒸发器,可降低空气流的湿度。为了提高在第一冷凝器(18)处可供使用的加热功率,借助于第二膨胀装置(72)使制冷介质的另一子流膨胀并将其输送给第二蒸发器(64)。来自蒸发器(38、64)的制冷介质被输送给压缩机(16)的吸入侧(48)。此外,本发明涉及一种具有制冷介质回路(10)的机动车。
