Do You Need Variable Frequency Drives In HVAC Intalls?

VFD: The Remote Control of your HVAC System 

Heating up and cooling down your home is like a cool and amazing thing to do. Thinking that you can control the temperature depending on the desired mood you have is a big help to maintain a comfortable environment and will let you reduce the stress you have for the day. Your own HVAC system or “Heat, Ventilation, and Air condition” system is the one responsible for this. But did you know that these sets of systems will not that successfully work without the help of other components, and one of these components are the “variable frequency drives” or VFDs. So, what is VFD and how does it work in our HVAC networking?

Variable Frequency Drives or VFD is like a remote control of your television. This is a motor controller that drives an electric motor by controlling or managing the frequency and the voltage of its power supply. It is like a throttle of a car, and talking about the HVAC networking, VFD is the responsible for adjusting the speed of an HVAC fan or pump motor. The adjustment of the HVAC fan is needed to save more energy and at the same time, it can prolong the life of your HVAC system. Studies show that through the help of VFD, there is a significant energy save and it can lessen the operating costs while using the equipment.

Furthermore, VFDs are like guards that will check first the system and will make everything ready before heating up the equipment. They serve a soft start that eliminates initial power surge or mechanical shock due to switching the motor from off to on. To be clearer, VFDs have the capacity to control the ramp-up or ramp-down of the motor. In more sense, without VFDs, your HVAC fan or pump motor is either 100% on or 100% off, there is no middle ground. 

There are so many reasons why we need VFDs in our HVAC system. As mentioned above, it can save more energy and can prolong the life of your equipment. Also, we want to adjust the mortar speed because we need to convert the power in hybridization applications, and we also need to match the speed of the drive to process the requirements of the equipment. VFDs are not present for additional expense but to lessen your additional expense. 

If you are now already thinking about integrating VFDs into your HVAC system, consider the total cost of the HVAC and the additional cost of the VFDs and compare it with the potential energy save. There is a significant advantage for you.
