3 Truths About Heat Pump Inverters & VFDs
Forget Multistage, Get a VFD An inverter and variable frequency drive (VFD), lets heat pump compressors run on minimal power. These special motors can scale up or down as needed. Think of a multi-speed motor, but instead of 3-5 speeds it has 35-70 different speeds. High-efficiency heat pumps save energy – and thereby money –
