Topic Description

This presentation will provide a technical overview of the transition from R410A to A2L refrigerants, primarily R32 & 454b, with a focus on their application in commercial HVAC systems. Key topics include the definition and characteristics of A2L refrigerants, briefly highlighting their differences in flammability and safety profiles compared to traditional refrigerants. The presentation will examine ASHRAE Standard 15-2022/2024, specifically updates for A2L refrigerants and the associated refrigerant mitigation measures, along with the calculation methods for determining required safety measures. Additionally, we will review UL 2-40, its relevance to refrigerant system certification, and its impact on the design and installation of systems using A2L refrigerants.
