FAQs : AIRSTAGE™ (VRF Systems) What is a VRF?

  • 0001


VRF is short for “Variable Refrigerant Flow”. It is a type of direct expansion (DX) multi-split system that incorporates a variable capacity compressor with a network of multiple indoor fan coil units. A VRF system increases efficiency by providing cooling or heating only to the individual zones where conditioning is required. Most VRF systems also employ a stand-alone controls and communications network.
