Abstract

PURPOSE: To enable to reduce the surging region by a method wherein the optimum width of diffuser is determined by the opening degree signal of inlet guide vane and the inlet temperature signal of cooling water.
CONSTITUTION: The opening degrees of guide vane D are divided into steps and, at each step and with every inlet temperature of cooling water around the step, the optimum width of diffuser W is determined by means of a controller 10. By means of the controller 10 serving as memtioned above, as the opening degree of guide vane D decreases with the decrease of refrigeration load, the signal of optimum width of diffuser determined by the opening degree signal of guide vane and the inlet temperature signal of cooling water is outputted from the controller 10 and the location of a movable diffuser 4 is determined with a control motor 7. In such a manner as mentioned above, the surging region can be reduced.
