The article examines variable refrigerant flow (VRF) zoning technology. Particular focus is given to how it is increasingly used for its superior energy-saving benefits and precise zoned control. Nevertheless, specifiers often find it challenging to compare the energy-efficiency data of traditional commercial HVAC with VRF zoning systems. This article poses five questions that specifiers should ask about energy-efficiency data for VRF zoning and other HVAC systems, and provides the answers.
