Green transformation of the refrigeration industry: the rise of natural refrigerants

Against the backdrop of global climate change, the refrigeration industry is facing a green transformation. Traditional refrigerants, such as Freon, have good refrigeration effects, but their destructiveness to the environment cannot be ignored. Therefore, finding more environmentally friendly alternatives has become an urgent need for the industry.

Natural refrigerants, such as carbon dioxide (CO2) and propane (R290), are gradually becoming the new favorites of the market due to their low global warming potential (GWP) and non-destructiveness to the ozone layer. These refrigerants are not only environmentally friendly, but also have a refrigeration efficiency that even exceeds that of traditional refrigerants in some application scenarios.

However, the popularity of natural refrigerants is not without challenges. For example, the operating pressure of the CO2 refrigeration system is higher, and the material requirements for pipelines and equipment are more stringent. Although R290 is not easy to liquefy at room temperature, its flammability requires special attention during design and installation. Therefore, the green transformation of the refrigeration industry requires not only the research and development of new refrigerants, but also the simultaneous upgrading of related equipment and technologies.

Despite the challenges, the development prospects of natural refrigerants are still widely optimistic. With the promotion of policies and the improvement of consumers' environmental awareness, the refrigeration industry is expected to achieve a smooth transition from traditional refrigerants to natural refrigerants in the near future.
