Abstract
The invention discloses a fluorohydrocarbon-containing composition which comprises the following components in parts by weight: 30-80 parts of 2,3,3,3-tetrafluoropropene, 5-50 parts of 1,1,1,2-tetrafluoroethane, 5-30 parts of difluoromethane, 5-25 parts of 1,3,3,3-tetrafluoropropene, 5-10 parts of fluoroethane and 0.1-1 part of a flame retardant. The compositions are useful as refrigerants, propellants and blowing agents for heating and cooling. The invention also discloses a preparation method of the fluorohydrocarbon-containing composition. The composition has the advantages of being low inGWP, environmentally friendly, good in refrigeration effect and good in lubricant compatibility.
Description
technical field [0001] The invention relates to the field of refrigerants, in particular to a composition containing fluorocarbons and a preparation method thereof. Background technique [0002] Currently, HFCs refrigerants, which are widely used in refrigeration and air-conditioning industries, are facing stringent reduction plans due to their very high global warming potential (GWP). At the same time, the fluorine-containing greenhouse gas control regulations passed by the European Union require that from January 1, 2017, the GWP of automotive air-conditioning refrigerants shall not exceed 150; the GWP of commercial refrigerators and freezers shall not be high from January 1, 2020. At 2500, the GWP will not be higher than 150 from January 1, 2022; the refrigerant used for mobile indoor air-conditioning equipment will not be higher than 150 from January 1, 2020, etc. [0003] Refrigerants in air-conditioning equipment in the Chinese market still rely on some HFCs with high...
