A refrigerant cycle system includes a variable displacement compressor, and first and second evaporators disposed in parallel. In the refrigerant cycle system, it is determined whether a refrigerant flow amount from the compressor is in a low flow amount area when first and second blowers for blowing air to the first and second evaporators are operated at the same time. When it is determined that a predetermined time passes after the refrigerant flow amount is determined to be in the low flow amount area, the operation of the compressor is forcibly switched between a large discharge capacity and a small discharge capacity. Accordingly, it can prevent oil returning to the compressor from being short due to the operation of the compressor in the low flow amount area.
