It’s not a new technology, but it’s more popular than ever. While VRF is providing engineers and building owners with a financial payback, the benefits go beyond energy efficiency.
Since the early 1980s, variable refrigerant flow systems have been a great option for engineers and building owners in need of an alternative to typical heating and cooling in the commercial sector. However, the technology really didn’t take off in the U.S. until about a decade ago.
