Abstract:
A reference cycle system comprising:a compressor for compressing and discharging refrigerant, the compressor being a variable type in which a flow amount of refrigerant discharged from the compressor is variable; first and second evaporators into which refrigerant circulates by operation of the compressor, the first and second evaporators being disposed in parallel; a first blower for blowing air to the first evaporator; a second blower for blowing air to the second evaporator; and a control unit for controlling the operation of the compressor, wherein: the control unit includes determining means for determining whether the flow amount of refrigerant discharged from the compressor is in a low flow area when both the first blower and the second blower are operated at the same time, and control means for forcibly switching the flow amount of refrigerant discharged from the compressor between a first state where the flow amount of refrigerant discharged from the compressor is smaller than a first value in the low flow area, and a second state where the flow amount of refrigerant discharged from the compressor is larger than a second value that is larger than the first value, when the operation state in the low flow area is continued for a predetermined time after the determining means determines that the flow amount of refrigerant discharged from the compressor is in the low flow area.
