Abstract
The refrigerant composition for replacing R134a in automobile air conditioner consists of dimethyl ether DME or RE170, trifluoro iodo methane R13I1 and isobutene R600a; and is prepared through liquid phase mixing the said components in certain proportion physically. The present invention has environment friendship, zero ODP, GWP lower of 1-3, heat engineering performance similar to that of R134a and high efficiency. The refrigerant composition is used for replacing R134a in automobile air conditioner.
Description
technical field [0001] The invention belongs to the field of refrigerants and relates to a refrigerant composition, in particular to a refrigerant composition used in automotive air-conditioning systems to replace 1,1,1,2-tetrafluoroethane (R134a). Background technique [0002] Because 1,1,1,2-tetrafluoroethane (R134a) is non-toxic, non-flammable, non-corrosive, and has good material compatibility, it is widely used in automotive air conditioners and other refrigeration systems. However, due to its high greenhouse effect potential value (GWP value) (up to 1300), according to the requirements of the fluorinated greenhouse gas (F-gas) control regulations passed by the European Union: from January 1, 2011, the European Union will ban Newly produced automotive air conditioners use refrigerants with a GWP value greater than 150; during the six years from January 1, 2011 to January 1, 2017, in-use automotive air conditioners will gradually phase out refrigerants with a GWP value g...
