Abstract
PURPOSE: To keep a refrigerating capacity of compressors constant at all times by unloading cylinders in sequence according to revving up the compressor of multicylinder.
CONSTITUTION: A compressor 3 is arranged in multicylinder 14, 15, 16, each cylinder is provided with unloading solenoid valves 14', 15', 16', and a regulator 13 to control above unloading solenoid valves 14', 15', 16' through detecting number of revolutions is connected to the compressor 3. Where the compressor 3 runs at low speed, the unloading solenoid valves are all opened by the regulator 13, thereby operating the three cylinders 14, 15, 16 effectively. Then in accordance as the compressor 3 revs up, the unloading solenoid valves 14', 15', 16' are closed in sequence to unload the cylinders 14, 15, 16 accordingly. Thus a refrigerating capacity is not increased regardless of the compressor 3 revving up, and the refrigerating capacity can be kept constant at all times consequently.
