In general, the development trend of refrigerants should meet the requirements of sustainable development of ecological environment, and promote its further development. According to the core requirements of coordinated development of economic development and protection of resources and the protection of the ecological environment, there are two directions for the development of refrigerants:
One is environmentally friendly, the use of green environmental protection is already the trend, green environmental protection can be synthetic, it can be natural, although the synthesis of environmentally friendly refrigerants will not cause damage to ozone, but the ecological sustainability of the Earth Development of natural refrigerants is the best choice, because the natural refrigerant is inherent in the Earth's ecosystem, whether it is used or discharged into the environment, taken from the natural back to nature, the impact on the environment than synthetic refrigeration Agents are small, I believe that with the continuous progress of technology, natural refrigerant will be a great development. The alternative research work on refrigerants has been developed in the direction of environmental protection and has been greatly promoted for the sustainable development of the environment. In September 2003, the United Nations Environment Program (UNEP) and the United Nations Environment Program (UNEP) The International Meteorological Organization (WMO) in Paris published an assessment report on the status of the atmospheric ozone layer, which was jointly organized by 250 experts from 37 countries. The report notes that since the Montreal Protocol on the Protection of the Ozone Layer has been signed by 183 countries, much has been done by the countries, and the atmospheric ozone layer has seen signs of recovery but remains fragile in the coming decades. Studies since 1998 have shown that the level of gas that destroys the stratospheric ozone layer has almost reached its peak, but the total amount of chemical substances that destroys the ozone layer in the troposphere is decreasing at a slow rate. The pattern is that the ozone layer over the Antarctic has been expanding for decades, but in recent years the pace has slowed down below the 80s of last century; the ozone layer above the Arctic is narrowing, indicating that the ozone layer is recovering.
The second is energy saving, with the improvement of people's living standards Refrigeration and air conditioning and other equipment more and more popular, while its consumption of a large number of energy is also attracting more and more attention, this summer 18 provinces and cities in China power shortage problem, China A survey conducted by the SERC shows that the intensification of contradiction between supply and demand has contributed to the tightening of electricity this summer, in which the rapid growth of air conditioning and refrigeration load is a factor that can not be ignored. China's East China, Central China, South China continued high temperature, air conditioning cooling load soared. East China Power Grid, China Southern Power Grid, Central China Power Grid air conditioning cooling load ratio has more than 30%, individual power grid or even close to 40%. The production of electricity and the consumption of a large number of fossil fuels, such as coal, oil, etc., not only caused a lot of non-renewable energy consumption, and combustion products such as CO2 can also cause greenhouse effects and other environmental problems. So in addition to improving the cooling technology can also start from the refrigerant, through the development of new energy-saving refrigerants to reduce the energy consumption of refrigeration and air conditioning equipment is also a development direction. In summary, the development of refrigerant is closely related to the sustainable development of environmental protection and the ecological environment of the earth. The development trend of refrigerant reflects the requirement of environmental sustainable development.
