How to Choose the Right VRF and VRV Pipe Insulation

Choosing the right VRF and VRV pipe insulation system can deliver countless benefits. Although variable refrigerant flow (VRF) or variable refrigerant volume (VRV) systems have been available in other countries for about three decades, this HVAC technology has only been available in the U.S. market for a decade or so. In that relatively short period…
