Page view
[Abstract]:
● 75% AC drive for pumps and fans
● If the AC drive is used for every suitable device, the global energy consumption will be reduced by 10%.
◇The solution being
Energy conservation,
Low carbon, energy efficient,
It is a major trend in international energy development.
Reduce the dependence of all industries on energy,
Not just energy saving,
It will have a significant positive impact on our economy and climate.
Today, Xiao Dan starts with his own major and sets an example. Let's talk about things related to energy efficiency...
Why start with the motor?
According to the World Energy Outlook, the power consumption of the motor system is more than 50% of the global total, accounting for half of the world's electricity consumption. Such a large proportion can not attract people's attention! Of these, nearly 30% are consumed by industrial systems. According to available data, by 2040, the total demand for industrial motor energy services is expected to double globally, with about half of the growth coming from China and India.
Under such a huge challenge, if you can effectively improve the system efficiency of the motor, you can make a big step on the road of human energy efficiency! The key to improving the efficiency of the motor system is the popularity of the inverter. According to the data, nearly 80% of the motor systems that are currently in use are not equipped with frequency converters, which means that they are running at full speed and full load from start to finish without considering the actual demand. Caused a certain amount of waste.
What is a frequency converter?
The frequency converter is used to control the speed of the motor to:
● Improve process control
● Reduce energy consumption and improve energy efficiency
● Reduce mechanical stress on the motor control equipment
● Optimize the operation of various motor-dependent devices
The frequency converter can also be used to convert the amount of electricity from natural renewable energy sources such as solar, wind or tidal energy, and then transfer it to the grid or for local energy consumption. In hybrid technology, frequency converters are used to combine traditional energy and energy storage technologies to create integrated energy management solutions.
Hey, you know?
●Emerging economies are causing increased energy consumption
●Electric energy consumption accounts for 20% of the world's energy consumption.
●40% of electrical energy for the motor
● 75% AC drive for pumps and fans
● If the AC drive is used for every suitable device, the global energy consumption will be reduced by 10%.
◇The solution being used
Installing a frequency converter increases the efficiency of standard motor systems with variable loads by 15 - 35%. The average payback period is rarely more than three to four years, so such investment is a very cost-effective measure.
◇Global potential
The motor system can save an average of up to 40% in energy consumption by adopting a series of related policy measures, including: stricter regulation of the motor system, more use of the frequency converter, and energy efficiency measures for other parts of the system. These actions will result in a 8% global power consumption savings by 2040.
Although inconspicuous, the frequency converter plays an indispensable role in modern daily life, making the world and our lives more sustainable. By using inverters and other system efficiency measures, we can reduce motor energy consumption by at least 40% and 8% of global power consumption (IEA Report 2016), with a payback period of about 2-4 years, and the effect is remarkable!
