Carbon dioxide refrigerant (R744 refrigerant) has a wide range of applications. Our industry is still in its infancy.

Carbon dioxide refrigerant, also known as R744 refrigerant, refers to a refrigerant made from a mixture of carbon dioxide and hydrocarbons as its main components. Compared with traditional Freon refrigerants, carbon dioxide refrigerants have the characteristics of good chemical stability, low greenhouse effect, and excellent refrigeration performance. They are widely used in automotive air conditioning, cold chain logistics, ice and snow sports and other fields.

Carbon dioxide refrigerant has a very low GWP value and is the cleanest and most environmentally friendly refrigerant. However, due to the problems of low critical temperature and high critical pressure of carbon dioxide, when it is used as a transcritical refrigerant, the performance and quality requirements of refrigeration equipment are extremely high, resulting in further increase in operating costs and replacement costs. In recent years, Chinese enterprises and scientific research institutions have continuously increased their investment in research and development of carbon dioxide cascade refrigeration technology, driving the carbon dioxide refrigerant industry to gradually develop in the direction of low cost and high quality.

According to the “2023-2028 China Carbon Dioxide Refrigerant (R744 Refrigerant) Industry Market In-depth Research and Development Prospects Forecast Report span>》shows that carbon dioxide refrigerants are widely used in automotive air conditioning, cold chain logistics and other fields. In the field of automobile air conditioning, carbon dioxide refrigerant has excellent performance and can meet the requirements of low carbon emissions, safety and non-toxicity; in the field of cold chain logistics, carbon dioxide refrigerant can condense at low temperature and high pressure, and then sublimates to achieve refrigeration and cooling purposes. Traditional refrigerants used in cold chain logistics vehicles have high energy consumption and easy leakage. Carbon dioxide refrigerants have the advantages of safety and energy saving, and are expected to have broad application prospects in the field of cold chain logistics of agricultural products in the future.

In recent years, with in-depth research and development and technological progress, the field of ice and snow sports has gradually become an emerging demand side for carbon dioxide refrigerants. The 2022 Beijing Winter Olympics speed skating venue uses a transcritical refrigeration system using carbon dioxide refrigerant as the refrigeration medium. This system has the advantages of uniform ice temperature, waste heat recovery, and large refrigeration load. It is the world’s largest carbon dioxide transcritical refrigeration system. Critical refrigeration system.

The main manufacturers of carbon dioxide refrigerants in my country include Binglun Environmental Technology Co., Ltd., Beijing Dinghan Technology Co., Ltd., Fujian Snowman Co., Ltd., etc. At present, my country’s carbon dioxide refrigerant industry is still in its infancy, with a small number of manufacturing companies. In the future, with technological upgrading and increasingly strong market demand, the number of companies in my country’s carbon dioxide refrigerant industry will further grow.

Industry analysts said that as a clean and environmentally friendly refrigerant, carbon dioxide refrigerant has excellent performance and has broad application prospects in many fields, including ice and snow. The sports field is its emerging demand side. In recent years, benefiting from the improvement in the level of technological innovation of local companies, the development speed of my country’s carbon dioxide refrigerant industry has accelerated. In the future, as the number of production companies increases, its market competition will become increasingly fierce.
