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.
