The history of refrigeration technology is actually the history of refrigerant development process. In the early days, people used the evaporation effect of storing natural ice and water and some other methods to refrigeration. In the 1930s, Perkins invented the vapor compression refrigeration cycle, and mankind ushered in the development period of refrigeration technology. The invention, renewal and replacement of refrigerants throughout the entire process. At present, according to the development requirements of the new era, refrigerants will face new challenges. At present, the development of refrigerant is divided into four stages, and the characteristics of each stage are shown in the left figure.

In general, the development trend of refrigerant should meet the requirements of sustainable development of ecological environment and promote its further development. According to the core requirements of coordination between economic development, resource protection and ecological environment protection in sustainable development, there are two development directions of refrigerant:

The first is environmental protection. It is a general trend to use green refrigerants. Green refrigerants can be synthetic or natural. Although synthetic environmental refrigerants will not damage ozone, natural refrigerants are the most ideal choice for the sustainable development of the earth’s ecology.

The second is energy conservation. With the improvement of people’s living standards, refrigeration, air conditioning and other equipment are becoming more and more popular, and at the same time, a large amount of energy consumed by them is also attracting more and more attention. This summer, 18 provinces and cities in China experienced a shortage of electricity. A survey by the China Electricity Regulatory Commission showed that the intensification of the contradiction between supply and demand caused a shortage of electricity this summer, of which the rapid growth of air-conditioning refrigeration load is a factor that cannot be ignored. Therefore, in addition to improving refrigeration technology, we can also start from refrigerants. It is also a development direction to reduce the energy consumption of refrigeration and air-conditioning equipment by developing new energy-saving refrigerants.

To sum up, the development of refrigerants is closely related to environmental protection and the sustainable development of the earth’s ecological environment. The development trend of refrigerants reflects the requirements of sustainable development of the environment.
