Variable Refrigerant Flow (VRF) systems have rapidly become one of the fastest-growing segments in the commercial HVAC industry, thanks to their flexibility, superior comfort, and exceptional efficiency. Recent U.S. regulations mandate a transition to new A2L-classified refrigerants. Updated refrigerant safety standards now provide guidance for designing VRF projects using this new class of refrigerants. This session will explore the A2L refrigerant transition for VRF and Ductless systems, focusing on its impact on design and installation.
Learning Objectives:
Understand the impact of the A2L refrigerant transition and review timelines for VRF and Ductless products.
Examine the key changes in ASHRAE 15-2022 affecting VRF and Ductless design.
Apply ASHRAE 15 EDVC calculations to assess compliance in practical scenarios.
Review the new guidelines for the location and installation of A2L refrigerant piping.
