VRF - The Future of HVAC

VRF - The Future of HVAC

March 22, 2017, 10:15 AM - 11:15 AM

Level 1, 1C02


Variable Refrigerant Flow (VRF) is a ductless system using refrigerant for both heating and cooling, having a single air or water cooled condenser connected to multiple evaporator units that work only when needed.  This is possible with the inverter-driven compressor technology that can simultaneously heat and cool.  Efficiencies can result in a 50% utility savings.  Additionally, VRF runs quiet, compared to other HVAC system; requires low maintenance; and they have a lower life cycle cost.

During this panel discussion, Dan Donnelly will provide an overview of technology today and what is coming in the future as it relates to HVAC and describes how VRF is already being used in NYC high-rise buildings. Andre Robitaille will explain Variable Refrigerant Flow (VRF): What it is, how it works and how it substantially reduces energy and downtime.  And Rich Rogers will detail technical aspects and describes some actual installations.

The presentation will be informal and will encourage interaction, comments, and questions throughout.
