The invention relates to a refrigerant circuit system and a control method thereof. The refrigerant circuit system includes: a compressor configured to compress a refrigerant; a condenser configured to cause the compressed refrigerant to release heat; first and second evaporators each configured to depressurize and expand a refrigerant releasing heat by adjusting an opening degree of the valve, the first and second evaporators disposed in parallel and configured to cause the refrigerant depressurized and expanded by the first and second expansion valves, respectively, to absorb heat; and a controller configured to adjust the temperature of the first temperature adjustment object adjusted by the first evaporator, the temperature of the second temperature adjustment object adjusted by the second evaporator, and the superheat degree of the refrigerant at the inlet of the compressor based on first information related to the temperature of the first temperature adjustment object adjusted by the first evaporator, second information related to the temperature of the second temperature adjustment object adjusted by the second evaporator, and third information related to the superheat degree of the refrigerant at the inlet of the compressor. The valve opening degree of the first expansion valve and the second expansion valve and the compression ratio of the compressor to the refrigerant are controlled.

    本发明涉及制冷剂回路系统及其控制方法。制冷剂回路系统包括:压缩机,压缩机被配置成压缩制冷剂;冷凝器,冷凝器被配置成使压缩的制冷剂放出热量;第一和第二蒸发器,所述第一和第二蒸发器每个均被配置成通过调节阀开度来使放出热量的制冷剂减压和膨胀,第一和第二蒸发器并联设置并且被配置成使分别由第一和第二膨胀阀减压和膨胀的制冷剂吸收热量;和控制器,控制器被配置成基于与由第一蒸发器调节的第一温度调节对象的温度有关的第一信息、与由第二蒸发器调节的第二温度调节对象的温度有关的第二信息和与在压缩机的入口处的制冷剂的过热度有关的第三信息,来控制第一和第二膨胀阀的阀开度和压缩机对制冷剂的压缩比。
