Refrigerant CO₂

Discover our eco-friendly refrigeration systems with the refrigerant CO₂ (R744, carbon dioxide), with a GWP value of 1. By using a CO₂ refrigeration system, you are opting for a long-term and efficient solution for many cooling tasks. No standards or laws prohibit the use of the natural refrigerant CO₂.

Classified as an A1 refrigerant, it can be used largely without restrictions.

In commercial refrigeration, CO₂ has become the standard refrigerant, due to the widespread use of booster systems. Its thermodynamic properties allow it to be used in a wide range of applications. Auch in Industrie, Lebensmittelherstellung und -lagerung werden zunehmend unsere CO₂ Maschinen eingesetzt.

What are the advantages of CO2 as a refrigerant?

CO₂ (R744) as a refrigerant offers a number of advantages that make it particularly attractive for various applications:

Environmentally Friendly: with a Global Warming Potential (GWP) of 1, carbon dioxide contributes only minimally to the greenhouse effect.

Efficient Heat Transfer: CO₂ has excellent thermodynamic properties. The high heat transfer rates lead to highly efficient refrigeration systems.

Non-Flammability: Carbon dioxide is a non-flammable refrigerant and as such, is categorised in safety group A1.

Non-Toxicity: CO₂ is non-toxic and poses no health risk if handled correctly. It is the first choice for a natural refrigerant that is non-toxic and non-flammable.

Availability and Cost: CO₂ is widely available as a natural refrigerant and is relatively inexpensive compared to synthetic refrigerants.

Versatile: Carbon dioxide can be used for a variety of applications, from commercial cold stores and supermarkets to industrial cooling processes and heat pumps.

However, it is important to note that carbon dioxide also presents challenges. Because of the high operating and standstill pressures, appropriate safety equipment is essential.

Is handling carbon dioxide as a refrigerant dangerous?

Carbon dioxide (CO₂ or R744) is a safe and non-flammable refrigerant that is used in refrigeration systems and heat pumps. However, there are some aspects to consider when handling this refrigerant.

CO₂ has a higher operating pressure than many other refrigerants. Special precautions and equipment are therefore required.

Even though CO₂ is non-toxic, a high concentration in the air can lead to health problems. In enclosed spaces, excessively high concentrations of CO₂ can lead to unconsciousness or even death by asphyxiation. Suitable ventilation systems and CO₂ detectors are therefore required in order to ensure a safe working environment.

Overall, handling carbon dioxide as a refrigerant is only safe if appropriate safety measures and regulations are observed and complied with. The professional education and training of technicians and fitters is crucial for safe and efficient system operation.

Are CO2 refrigerants affected by the F-Gas Regulation?

No, the refrigerant CO₂ (R744) is not covered by the F-Gas Regulation. This regulation was introduced in order to control and reduce the use and release of fluorinated greenhouse gases (F-gases). Fluorinated greenhouse gases are a group of industrially produced gases with a high global warming potential, that are used in a variety of industries.

Carbon dioxide, on the other hand, is a naturally occurring gas without fluorine or fluorinated components, with a global warming potential (GWP) of 1.

Because of its environmental friendliness and high efficiency, it is increasingly being used as a refrigerant. It is important to note that although CO₂ has a small impact on global warming, it still contributes to it. Responsible handling of CO₂ is a condition of environmentally friendly and safe system operation.
