What Is a Variable Speed Compressor (VFD Compressor)? | HVAC Explained

Описание: What’s actually going on inside a variable speed compressor? In this video, we’ll break down how a VFD (Variable Frequency Drive) or inverter-driven compressor works, why it’s used, and how it compares to a traditional on/off scroll compressor.

We’ll look inside the compressor, explore how scroll plates compress refrigerant, and show you exactly how varying motor speed helps achieve better temperature and humidity control — while dramatically improving system efficiency.

You’ll learn:
✅ The internal operation of a scroll compressor
✅ How VFD compressors change motor speed to match system load
✅ Why variable speed improves comfort and efficiency
✅ Real-world comparisons for chillers and rooftop units
✅ The difference between VFD compressors and digital scroll (VCC) compressors

If you’re in HVAC design, service, or sales — or just want to understand how modern systems get so efficient — this one’s for you.
