Advantages of using an inverter on refrigeration systems
Using an inverter with a refrigeration compressor can grant several advantages: Continuous regulation of compressor’s cooling capacity Drastic reduction of temperature’s variations in the cold room, better product’s conservation, optimized heat exchange Stable operating pressures and higher T evap. ↔ better system’s COP Optimization of control logics of rack units and its adaptability to system’s load avoiding useless and expensive start-stop cycles Improved system’s efficiency at partial load. Estimated 20-30% energy savings, compared to on-off regulation Relevant reduction of starting currents Compared to a normal current absorption at start-up equal to 5 - 8 times nominal current, inverter limits the maximum current at start-up to the nominal current value eliminating stresses for the motor/compressor for the whole system Reduced risk of liquid flow back at start-up, thanks to the soft-starting Reduced noise especially ...
