About this program:

This panel discussion focuses on variable refrigerant flow (VRF) technology, a heating and cooling solution that is quickly being adopted in Maine schools and commercial buildings. The technology is exciting because these systems can simultaneously and efficiently heat and cool different parts of the building by  taking waste heat captured in one part of the building and delivering it to spaces that need  heat. These systems have the ability to control the amount of refrigerant to the indoor units, which makes VRF/VRV technology ideal for applications with varying loads or where zoning is required. The panel will cover the kinds of buildings and situations where variable refrigerant flow systems are appropriate, costs and benefits of VRF systems, and things to consider when choosing between VRF and other systems like a multi-zone high-performance heat pump.  It will highlight a recent study of economic opportunities for Variable Refrigerant Flow (VRF) systems which finds that in the right situation, VRFs can cost-effectively provide heating and cooling for Maine’s businesses and institutions. The report was prepared by Energy Resource Solutions (ERS) of Augusta, ME, 3/9/2020.  Moderated by EMT Staff member.  Panel to include the study authors.
