PROBLEM TO BE SOLVED: To unify refrigerant diffluence of an evaporator by accurately detecting nonuniformity of the refrigerant at each flow channel outlet of the evaporator. SOLUTION: This refrigerating cycle device is constituted by mounting a first flow rate control valve 105 for controlling the quantity of refrigerant flowing in a first evaporator, a second flow rate control valve 106 for controlling the quantity of refrigerant flowing in a second evaporator, a first refrigerant temperature detecting means 107 for detecting a refrigerant temperature of a first evaporator outlet, a second refrigerant temperature detecting means 108 for detecting a refrigerant temperature of a second evaporator outlet, and a control means 109 for controlling a throttle 103, the first flow rate control valve and the second flow rate control valve on the basis of the first refrigerant temperature and the second refrigerant temperature, in a refrigerating cycle circuit formed by successively connecting a compressor 101, a radiator 102, the throttle 103, and the first evaporator 104a and the second evaporator 104b in parallel with each other, the refrigerant diffluence can be surely unified by reducing an opening of the throttle 103 by the control means 109.
