Problems solved by technology
However, due to the defects of high pressure and high greenhouse effect (GWP) in the practical application of this mixed refrigerant, many technicians are still looking for a refrigerant that can replace R12
High-pressure refrigerants are not suitable for use in high-temperature areas, which limits the scope of product use; high greenhouse effect (GWP) will increase global temperature, thereby increasing natural disasters

The invention discloses a refrigerant, which comprises the following parts: 30-50% difluo-monochloromethane, 30-55% difluo-monochloroethane and 1-15% difluoroethane. The invention can replace R12, which possesses low pressure, low green-house effect value in the high temperature area.
Description
technical field [0001] The invention relates to a refrigerant, in particular to a refrigerant which can replace R12 and is suitable for corresponding refrigeration equipment. Background technique [0002] Freon R12 is a refrigerant with excellent thermal performance. Its chemical properties are stable, non-toxic and non-flammable. It has been widely used in automobile air conditioners and household refrigerators for a long time. However, since scientists discovered that chlorofluorocarbons (CFCS) are released into the atmospheric stratosphere and will deplete the ozone layer under the action of ultraviolet rays, its production and use have been restricted by international conventions. So far, many developed countries have stopped production, and my country has also The production volume was gradually reduced according to the plan and the production was stopped at the end of 2010. [0003] The mixed refrigerant R406a is currently the most important...
