PURPOSE:To make the stable and continuous operation of regrigerator feasible regardless of the load fluctuation of magnet coil by a method wherein a heat exchanger is constituted to fill the roll of adjusting load on the refrigerator. CONSTITUTION:When the primary cooling water temperature falls below the temperature specified by a controller 13, the controller 13 is actuated by the signals from a temperature detector 12 to make a transfer control valve 11 open upward in the arrow direction. The secondary cooling water heated by a refrigerator 4 is returned to a cooling tower 6 through a heat exchanger 10. The primary cooling water in the heat exchanger 10 loaded with heat runs through the refrigerator 4 to make the refrigerator 4 continuously operate without stopping at all. On the contrary, when the load on magnet coil 3 is increased to make the water temperature detected by the temperature detector 12 exceed the temperature specified by the controller 13, the controller 13 is actuated to make the control valve 11 open leftward in the arrow direction. At this time, the second cooling water is returned to the cooling tower 6 bypassing the heatexchanger 10. |
