Fan Frequency Inverter Energy Conservation Solution
I. Characteristics and effects of fan frequency inverter energy conversion systems
1. Unparalleled superiority in variable frequency air regulation, remarkable energy-saving effect.
According to principles of fluid mechanics, the rotational speed N is proportional to the flow rate Q of fan and pump loads, and the required power P is proportional to the N cubed. So when the air volume is less than the nominal value, changing the motor speed will reduce the power consumption, with a significant energy saving effect.
2. Greatly improved fan efficiency.
With easy operation and low maintenance, the fan efficiency will be greatly improved. The continous adjustment is enabled within a certain range, and the soft start allows the motor to run stably and smoothly at variable speed.
II. Significance of fan upgrading
1. Using AC inverter for the energy conservation upgrading on the fan and pump, is to simplify the structure, improve the energy saving effect, and accelerate investment return. The upgrading is easy to be carried out.
2. Equipped with the inverter, the fan will be capable of soft start and stop. The upgrading will reduce the mechanical shock on the equipment, extend equipment life, and reduce maintenance costs.
3. Advanced and mature frequency control technology will improve the technological value of the equipment.
