A pulse tube refrigerating system includes a first space, a second space, a pulse tube disposed between the first and the second spaces so as to constitute a closed operating space in which an amount of operating fluid is filled, a driving device for establishing opposite phase fluctuations of the operating fluid by an expansion and an compression of the first space and the second space in alternative manner, a first set of a radiator and an accumulator disposed in the pulse tube so as to be located at a side of the first space, a second set of a radiator and an accumulator disposed in the pulse tube so as to be located at a side of the second space, a phase control oscillator disposed in the pulse tube and set to be be vibrated with a phase relative to the fluctuation of the operating fluid, and a control device for controlling the phase of the phase control oscillator relative to the fluctuation of the operating fluid.
