Refrigerants are classified by chemical family, pressure characteristics, ODP (Ozone Depletion Potential), and GWP (Global Warming Potential). Modern EPA focus emphasizes low-ODP and lower-GWP alternatives. Key comparisons: • R-22: HCFC, phased out (high ODP) • R-410A: HFC blend, higher pressure than R-22, zero ODP but higher GWP • A2L refrigerants: mildly flammable, lower GWP replacements emerging Related: NATE: EPA 608 Core Concepts - Sections, Types and Responsibilities
