Abstract
PURPOSE: To make it possible to obtain a high efficient operation by controlling a revolution speed of a compressor as well as the volume of injecting lubricant of the compressor and the opening position of an outlet nozzle in proportion to thermal load.
CONSTITUTION: A cooling equipment 4 is provided with a thermal load detector 9. The thermal detector 9 is connected to a rotary speed setting equipment 11, an oil volume controller 15 and an outlet nozzle controller 16 through a load controller 10. With this construction, the rotary speed of a compressor, the volume of injecting lubricant for the compressor as well as the position of an outlet opening can be controlled, thereby making it possible to obtain a high efficient operation.
