Why CO2 as a Refrigerant?
CO2 (Carbon dioxide or R744) is a natural refrigerant, like ammonia and hydrocarbons. It's chosen for its low environmental impact and energy efficiency. - CO2 has a Global Warming Potential (GWP) of 1, making it climate-friendly.
- Alternatives like R507A have much higher GWPs.
Environmental Benefits:
CO2's Unique Properties
Non-toxic, non-flammable, and safe.
Operates at high pressure (90 to 130 bar), requiring different system design and maintenance
Efficient for freezing applications like fish, offering better quality and lower energy consumption.
Specially adapted compressors available for different temperature stages
Phasing Out Harmful Substances
- The Montreal Protocol mandates phasing out ozone-depleting substances like CFCs and HCFCs.
- CO2 is a safe, environmentally acceptable, and practical alternative.
- Scientists have developed substitutes like R134a, R407C, and R290 for various applications.


Choosing the Right Refrigerant
- Refrigerants are crucial in cooling and heating systems.
- CO2 stands out due to its unique properties and environmental friendliness.
