VFD also known as variable frequency drive systems, are a type of motor drive that we find everywhere in the latest commercial heating and cooling systems. In supermarkets, modern commercial HVAC equipment, and industrial systems we will find a VFD almost everywhere. VFDs operate on the principle of energy savings by lowering the amount of frequency and alternating the current wavelengths to meet the required load capacity. VFDs’ whole purpose is to save energy because every time the compressor/motor goes on and off it surges power. Now every time the power surges it consumes a lot of electricity. VFDs prevent this by alternating the current frequency so that the compressor/motor can still run at minimum loads. According to the manufacturer of the VFD, it can be programmed through various software’s. VFD can go very complicated sometimes when it comes to troubleshooting and require expert technicians to handle and troubleshoot them properly. We at DHVAC HEATING, REFRIGERATION, APPLIANCES, AND AIRCONDITIONING SYSTEMS do full supply, maintenance, servicing, and installations of systems that contain VFDs for supermarkets, commercial and industrial needs. If you run a business where you needed to get servicing done or your system is not working properly. Feel free to contact our branches or you can even fill out our online service request form on our website or give us a direct call.
