Understanding VRF: Insights from Real-World Measured Performance

This session offers an opportunity for attendees to gain important insights into real-world performance of VRF systems and drivers that impact performance. Presenters will share results from two newly completed DOE-funded research studies focused on measured performance of VRF systems in cold climates. Come learn about the key findings, including VRF efficiency, refrigerant leakage, and the impacts of oversizing. Presenters will also discuss measurement methods and what the future of onboard measurement might look like. Leave with practical strategies to optimize VRF system performance during the design, installation, and operation process.
