Energy consumption of different speed control techniques in HVAC application
It's said that 40% of all power in Europe and North America is consumed in the buildings. The biggest share of the energy is consumed in heating, ventilation and air conditioning (HVAC) applications.
In China's power consumption, the power consumption by the buildings accounts for around 32 percent. Yes. The biggest share of that is in heating, ventilation and air conditioning (HVAC) applications too.
The situations of power consumption is similar in other countries and areas. Thus the energy savings potential in HVAC applictions is large. It is crucial to use all means available to reduce the energy consumption in the building, especially in HVAC applications.
As the figure above shows, variable speed drives (VSDs, AC drives, frequency inverters) allow you to consume less energy than any other speed control techniques when load requirements are less than full speed, as is usually the case in heating, ventilation and air conditioning (HVAC) applications.
Below is the picture of frequency inverters (AC drives, variable speed drives), which are widely applied in heating, ventilation and air conditioning (HVAC) applications for reducing energy bill.
