Core Advantages and Applications of the Product

Carbon dioxide (CO₂) is a natural refrigerant designated as R744 in the refrigerant numbering system.
It is a colorless, odorless, non-toxic, non-flammable gas that occurs widely in nature.
Within refrigeration systems, CO₂ absorbs and releases heat through processes such as compression, condensation, expansion, and evaporation to achieve cooling.
Hispania's CEA series and other products support CO₂ refrigerant. The equipment can be used for both standard freezing and deep-freezing applications, meeting diverse temperature requirements.

Global Regulatory Insights

Commercial Cold Chain Goes Fully CO₂: Supermarkets in Europe, America, and Japan are widely adopting R744 transcritical systems for their refrigeration units.
• Automotive Air Conditioning Electrification: Tesla, Toyota, and others have already implemented CO₂ heat pump air conditioning in select models.
• Green Building Cooling: CO₂ systems hold promising prospects in future urban energy systems due to their compatibility with heat pumps and energy storage.
CO₂ is considered one of the core elements of the “next generation of sustainable refrigerants.”
