Variable Refrigerant Flow (VRF) Heat Pump Systems in Cold Climates

Abstract

This field study was a side-by-side demonstration of two VRF heat pump technologies that offer significant potential for energy and cost savings, as well as improved comfort with zoned temperature control. The first VRF system was a natural gas engine-driven heat pump (GHP) - an emerging technology designed to reduce peak electric demand and generate savings in both annual energy costs and life-cycle costs compared to conventional equipment. The second VRF system was an electric cold climate heat pump (CCHP) - a relatively mature technology, designed for colder ambient conditions without supplemental heating. This document provides a summary of best practices and lessons learned from the ESTCP demonstration that can improve performance, energy efficiency, and/or minimize costs. Some of these best practices could be applied to existing HVAC equipment as well as the installation of new equipment.
