The State of the Technology: Variable Refrigerant Flow Heat Pump Systems

Jesse Remillard and Valerie Eacret, ERS, for Zondits ERS is wrapping up a study for the Northeast Energy Efficiency Partnerships for which we performed primary and secondary cost research for a variety of key emerging technologies. One of these technologies was the variable refrigerant flow (VRF) heat pump (HP) system. Variable refrigerant flow (VRF) systems

Ask the Expert: When Does VRF Make Sense? Part II

Technical Information on Variable Refrigerant Flow Systems Adam Allington and Chris Zimbelman for Zondits, December 17, 2015 Answer: A few months ago we asked the question when does VRF make sense? In short, the answer was that these systems are ideal in buildings with different rooms or zones that have varying occupancy schedules, activities, and temperature

Ask the Expert: When Does VRF Make Sense?

When Does a Variable Refrigerant Flow System Make Sense? Chris Zimbelman and Adam Allington for Zondits, June 2, 2015 In order to understand what the best applications are for variable refrigerant flow (VRF) systems, we should back up and discuss their operation and benefits first. VRF systems are a sophisticated type of air-source (or occasionally
