As a developing country, we should not only use and develop refrigerants that meet the requirements of the European Union, but also take our own situation into consideration and not completely copy the European standards.Refrigerant replacement is also related to the country's resources and interests, if we can more fully grasp the new refrigerant research and development and manufacturing technology, then, in the future, we do not have to spend a lot of money to import new refrigerant, which is very important for a large car country.

Like foreign manufacturers, Chinese automobile manufacturers and related equipment manufacturers also prefer to try to use new refrigerant without changing the existing air conditioning system structure.In the research and development of carbon dioxide refrigerant, domestic automobile air conditioning manufacturers have been paying close attention to the trend of European automobile manufacturers, although carbon dioxide refrigerant needs to update the whole air conditioning system, but some domestic air conditioning equipment manufacturers are also actively preparing.

Refrigeration is 30 years older than cars, but it took 54 years for air conditioning systems to be built into cars.As people's demand for refrigeration technology continues to change, the characteristics of refrigerants are also constantly optimized, from the initial availability to seek stability, and then to seek alternatives due to environmental problems. Now, in order to further reduce the impact of refrigerants on the environment, refrigerants will develop into the fourth generation.
