On March 19, the World Meteorological Organization (WMO) released the "State of the Global Climate in 2023" report. The report points out that 2023 will be the warmest year on record, and the past ten years have also been the warmest on record. United Nations Secretary-General Antonio Guterres said: All major indicators are on "alert"... Some data are not only among the best, but are even setting new records, and changes are accelerating.
The long-term increase in global temperature is mainly due to the increase in the concentration of greenhouse gases in the atmosphere. Real-time data from specific locations shows that greenhouse gas concentrations continue to rise through 2023. Carbon dioxide levels are 50% higher than in pre-industrial times, trapping heat in the atmosphere, and carbon dioxide is long-lived, meaning temperatures will continue to rise for many years to come.
As the average temperature gradually increases, people's dependence on air conditioners is also increasing, and the use of refrigerant products with higher GWP will emit a large amount of greenhouse gases, causing the global temperature to further rise, thus forming a vicious cycle.
Currently, the main refrigerants used in air conditioning equipment are R410A and R32, with GWP values of 1924 and 677 respectively. As global high temperature records continue to be refreshed, the replacement of refrigerants has become urgent. The Montreal Protocol and the Kigali Amendment respectively stipulate the reduction progress of HCFCs and HFCs refrigerants. They will be replaced by the more environmentally friendly and low-carbon fourth-generation refrigerants--HFOs refrigerants. HFO 1234YF refrigerant ODP The value is zero and has an extremely low GWP value. It has been widely used in some developed countries.
All in all, climate change is a common challenge for all mankind. Countries around the world should strengthen unity and promote cooperation. The refrigeration industry should continue to innovate low-carbon refrigeration technology, reduce carbon dioxide emissions, slow down the extent of global warming, and prevent mankind from suffering worse consequences. Climate disaster.
