VFD (Variable-frequency Drive)have been widely used in marine ventilation and air conditioning refrigeration systems:

The VFD can reduce the impact on the power grid, thereby effectively reducing the reactive power loss and increasing the effective power of the power grid.

The VFD can adjust the power of the motor to realize the variable speed operation of the motor, so as to achieve the purpose of saving electricity.

When the fans, water pumps and compressors use VFD, through frequency conversion speed regulation, the air volume, water flow and refrigerant flow can be easily controlled according to the needs, so that the operating conditions of the supporting equipment are more optimized and reasonable, thereby saving valuable energy.
