As the global push for clean energy and sustainable solutions intensifies, the refrigeration industry has been quick to adapt (perhaps somewhat surprisingly). One notable shift has been the increased use of R744, a refrigerant also known as CO2.
R744 is becoming a game-changer in the heat pump world as HVAC professionals and environmentally-conscious building and property owners are wisely turning their attention toward this option. Let’s take a closer look at R744 and discover why it’s quickly becoming a preferred choice in commercial and industrial heat pumps and refrigeration systems.
What Is It?
The term R744 refers to CO2 when it is used as a natural refrigerant in refrigeration and air conditioning purposes. At its core, R744 CO2 has excellent thermodynamic properties and offers significant advantages compared to classical and other alternative refrigerants, like high volume capacity and excellent heat transfer properties. This specialized gas allows for efficient cooling, especially in heat pump systems designed to handle its unique properties.
The Advantages
- Energy Efficiency:
- CO2 refrigeration is known for its high energy efficiency, in both hot and cold climates. The transcritical and subcritical cycles in CO2 systems allow for optimized energy use, leading to reduced electricity costs and lower carbon footprints. Over time, these systems can offer significant savings compared to conventional refrigerants.
- Environmental Impact and Benefits:
- R744 is a natural refrigerant with an extremely low Global Warming Potential (GWP) of 1, making it far more eco-friendly compared to traditional synthetic refrigerants like HFCs (hydrofluorocarbons) and HCFCs (hydrochlorofluorocarbons), which have much higher GWPs. Unlike these choices, R744 does not deplete the ozone layer, making it a sustainable choice for the future.
- Availability and Cost Effectiveness:
- CO2 is widely available and relatively inexpensive compared to synthetic refrigerants. Additionally, its abundant supply reduces the risk of shortages and price volatility, ensuring a more stable and cost-effective solution for businesses.
- Non-Toxic and Non-Flammable:
- As a non-toxic and non-flammable refrigerant, R744 ensures safety in various applications. This makes it an attractive option for industries where safety is a top priority, such as food processing, retail refrigeration, and healthcare, among others.
- Compatibility with Future Regulations:
- With every year, global governments continue tightening regulations on high-GWP refrigerants. Investing in R744 CO2 systems now ensures compliance with evolving environmental standards and laws, avoiding costly retrofits or replacements in the future.
- Versatility:
- R744 can be used in a variety of heat pump applications. Its adaptability makes it suitable for both small and large-scale operations, providing a flexible solution across different sectors.
Comparison With Other Refrigerants
Overall, when compared with traditional HFC refrigerants like R-134a and R-404a (Freon™) for example, R744 CO2 stands out for its superior performance and environmental merits. While HFCs have been standard in HVAC systems for years, their high GWP and potential for environmental harm are leading many building owners and facility managers to seek alternatives. R744 CO2 stands out as a viable solution—without sacrificing performance—thus proving itself in a variety of heat pump applications around the world.

R744: The Right Choice
So, what’s the bottom line? It’s clear why R744 CO2 is celebrated for its low environmental impact and increased efficiencies. Unlike traditional refrigerants that contribute to ozone depletion and global warming, R744 is a natural refrigerant with negligible effects on our planet. By opting for a CO2-based system, HVAC professionals and building owners can offer a sustainable solution that aligns with global efforts to protect the environment.
The advantages of R744 extend beyond just environmental benefits. Its energy efficiency, safety, cost-effectiveness, and regulatory compliance make it a compelling choice for businesses looking to future-proof their heat pump or refrigeration systems while minimizing their environmental impact.
