NATE Low-GWP Refrigerant Certification
Complete study program for the NATE Low-GWP Refrigerant Certification. Progress through 8 structured modules covering all exam topics.
- Compare GWP values of low-GWP refrigerants to legacy HFC refrigerants they replace
- Identify the safety classification (A1, A2L, A3) of common low-GWP refrigerants
- Explain how temperature glide affects system design and charging for zeotropic low-GWP blends
- Describe the operating characteristics of R-32, R-454B, R-1234yf, and R-290
- Explain the ASHRAE 34 safety classification system for refrigerants (A1, A2L, A2, A3)
- Define lower flammability limit (LFL) and burning velocity for A2L refrigerants
- Compare A2L ignition characteristics to A1 (non-flammable) and A3 (highly flammable) refrigerants
- Identify which common low-GWP refrigerants carry the A2L classification
