How can the inverter save energy? The frequency converter is a kind of electric energy controller , but the frequency changer can not save the electric quantity everywhere, there are many occasions to use the frequency changer but not necessarily can save the electricity. How can the inverter save energy? Xiaobian here to introduce you to specific about it.
As an electronic circuit, the inverter itself also consumes electricity (about 3-5% of rated power). A 1.5-air conditioner itself has 20-30W power consumption down, equivalent to a long light. Inverter frequency operation, with power-saving features, is a fact.
But his prerequisite is that the first big power is the fan / pump load; second, the device itself has a power-saving function (software support); third, long-term continuous operation. This is the three conditions that reflect the power saving effect. In addition, it does not matter that the festival does not save power, it makes no sense. If you say without precondition that the inverter power frequency energy-saving operation is to exaggerate or commercial speculation. Know the whole story, you will skillfully use him to serve you. Must pay attention to the use of occasions and conditions of use is correct, otherwise it is blind obedience, credulity and "deceived".
Power Factor Compensation Energy Saving: Reactive power not only increases line loss and equipment heat, more importantly, the reduction of power factor leads to the reduction of active power of the power grid, a large amount of reactive power is consumed in the circuit, the equipment is used inefficiently, the waste is serious, The use of frequency control device, due to the role of inverter internal filter capacitor, thereby reducing the reactive power loss and increase the active power grid.
Soft-start energy-saving: Motor hard-start has a serious impact on the power grid, but also on the grid capacity requirements are too high, start-up generated when the current and vibration damage to the baffle and the valve, the use of equipment, piping Life is extremely unfavorable. The use of inverter energy-saving device, the use of inverter soft-start function will start the current from zero, the maximum does not exceed the rated current, reducing the impact on the power grid and the power supply requirements, extending the use of equipment and valves life. Save the equipment maintenance costs. In theory, the frequency converter can be used in all mechanical equipment with a motor, the motor when starting, the current will be higher than the rated 5-6 times, not only will affect the service life of the motor but also consumes more power. In the design of the motor selection will leave some margin, the motor speed is fixed, but in actual use, sometimes to lower or higher speed operation, so the frequency conversion transformation is very necessary.
How to save energy inverter it has been introduced, and now we have learned about the inverter energy saving Know how the inverter is energy-saving. Users in the course of the future, will be more convenient will be more easy.
