The utility model discloses a frequency conversion refrigerator refrigerating system of variable flow, including connecting gradually into refrigeration circuit's frequency conversion compressor, condenser, filter, the capillary nest of tubes, evaporimeter, the capillary nest of tubes includes solenoid valve and a plurality of parallelly connected capillary, the length diverse of a plurality of parallelly connected capillaries, and a plurality of parallelly connected capillaries form independent a plurality of parallel branch, switch over through the solenoid valve and control opening or closing of a plurality of parallel branch, and refrigerating system still includes the controller, and frequency conversion compressor and solenoid valve all are connected with the controller and just all are controlled by the controller. The utility model discloses it has following advantage to compare prior art: the capillary that enables refrigeration circuit and to select different length is switched through the solenoid valve, the confession liquid measure of whole refrigerating system when different refrigerating outputs require can be satisfied to it is constantly changeable that adaptation frequency conversion compressor measures, guarantees refrigerating system's condensing pressure and evaporating pressure, makes the high -efficient work of whole refrigerating system reach more energy -conserving effect.
