Core Advantages and Applications of the Product

A2L is a refrigerant safety classification defined by ASHRAE 34 / ISO 817 standards. It balances high energy efficiency, environmental friendliness, and relative safety, establishing itself as the mainstream direction for the new generation of low-GWP refrigerants.
Hispania's AEA series and other products support conventional and mildly flammable refrigerants with safety classifications A2L, A3, and A1. The equipment is suitable for both standard freezing and deep-freezing applications, meeting diverse temperature requirements.

AEA and other series products

Technical Improvements and Safety Design

Key Technology Optimization

A2L and A3 products utilize specialized heating elements to reduce current density per unit area, optimizing the defrosting system (with rationally designed heating tubes that maintain safe surface temperatures while meeting defrosting requirements).

All components, including fans, compressors, and electrical components, meet the design requirements for A2L and A3.

Pressure and Quality Testing

Global Regulatory Insights

The Kigali Amendment is being implemented globally, phasing out HFC refrigerants (R410A, R134a).
Countries are promoting A2L refrigerants such as R32, R454B, and R1234yf.
Technological Maturity: Supporting technologies like new compressors, leak detection sensors, and fire-resistant structures are fully developed.
Market Adoption:
• Nearly 100% of Japanese air conditioners use R32.
• European automobiles have fully adopted R1234yf.
• China's air conditioner exports are rapidly transitioning to A2L refrigerants.
