The First Domestic Corporate Standard for Fourth-Generation Refrigerant (HFO-1234fy)

On March 18, China Huo Environmental Protection successfully held a corporate standard seminar "2,3,3,3-tetrafluoro-1-propene (aerosol tank type) for automotive air conditioning" in Shanghai. The meeting discussed and passed the corporate standard of HFO-1234yf aerosol cans to ensure the safety specifications, technical performance and use methods of HFO-1234yf.

　　 At present, R134a (GWP=1300) is the most widely used refrigerant for automobile air-conditioning, but its global warming effect is 1,300 times that of carbon dioxide. As environmental issues have become increasingly prominent, since 2017, new models produced and sold in Europe and the United States have gradually replaced R134a with HFO-1234yf (GWP<1). In order to meet the demand for maintenance and replacement of air-conditioning refrigerants for corresponding imported models in China, Sinochem Blue Sky Honeywell Environmental Protection Materials (Shanghai) Co., Ltd. launched the maintenance canned Golden Cold? | SpeedNet? HFO-1234yf for domestic imports Replenishment of refrigerant for automobile air-conditioning unit.

　　 The global warming potential (GWP) of HFO-1234yf refrigerant is less than 1, which can help automobile manufacturers meet EU requirements for automobile air-conditioning refrigerants. As an alternative to R134a, HFO-1234yf has high cooling energy efficiency, high safety, and does not need to change the existing mature automotive design, engineering manufacturing and service industry standards and practices. It is the preferred solution for the comprehensive performance of energy saving and emission reduction in the automotive air conditioning industry.
