A refrigerant circuit (1) comprising at least a compressor (2) having an upstream suction side (3) and a downstream pressure side (4), a condenser (5), a first evaporator (6) and at least one second evaporator (7); wherein the compressor (2) is an at least two-stage compressor, which has, on the suction side (3), a first feed line (8) leading to a first stage (9) of the compressor (2) having a first pressure level and a second feed line (10) leading to a second stage (11) of the compressor (2) having a second pressure level, the second pressure level is higher than the first pressure level; wherein the first evaporator (6) and the second evaporator (7) can be at least temporarily connected to the compressor (2) via different feed lines (8, 10) from one another. The invention further relates to a method for operating a refrigerant circuit.

    一种制冷剂回路(1),至少包括具有上游的吸入侧(3)和下游的压力侧(4)的压缩机(2)、冷凝器(5)、第一蒸发器(6)和至少一个第二蒸发器(7);其中,所述压缩机(2)是至少两级的压缩机,所述压缩机在所述吸入侧(3)上具有通向所述压缩机(2)的具有第一压力水平的第一级(9)的第一输入管路(8)和通向所述压缩机(2)的具有第二压力水平的第二级(11)第二输入管路(10),其中,所述第二压力水平高于所述第一压力水平;其中,所述第一蒸发器(6)和所述第二蒸发器(7)能够至少暂时地通过彼此不同的输入管路(8,10)与所述压缩机(2)连接。此外提出一种用于运行制冷剂回路的方法。
