All of us have probably heard about the ozone layer, which is located 35 miles above the ground. This upper layer of our earth\u2019s atmosphere protects the earth from the sun\u2019s ultraviolet rays by reflecting them back to space. UV rays are harmful to plants, marine life, and human beings on the earth.<\/p>\n<p>How does air conditioning relate to the ozone layer? It was discovered in the mid-1980s that the commonly used air conditioner refrigerant has a damaging impact on the ozone layer.<\/p>\n<p>At that time, the <a href=\"https:\/\/todayshomeowner.com\/hvac\/guides\/what-is-refrigerant\/\">refrigerants<\/a> that were used were known as CFC (chlorofluorocarbons) and HCFCs (hydrochlorofluorocarbons). CFCs are a family of chemicals that contain chlorine, fluorine, and carbon. The chlorine content in these compounds causes the depletion of the ozone layer.<\/p>\n<h2 class=\"wp-block-heading\" id=\"h-the-montreal-protocol-of-1987\">The Montreal Protocol of 1987<\/h2>\n<p>The discovery that refrigerants are harmful to the ozone layer prompted the signing of\u00a0the <strong>Montreal Protocol of 1987<\/strong>, an agreement signed by 180 nations that aimed to phase out the production of CFCs by 1995 and HCFCs by 2030. As of January 2012, all 197 countries in the world have ratified the Montreal Protocol.<\/p>\n<p>New refrigerants that are being used to replace these CFCs are HFCs (hydrofluorocarbons) and refrigerant blends (Azeotropic, Zeotropic). In summary, the 4 commonly used refrigerants that you can find today are:<\/p>\n<ul>\n<li>CFCs<\/li>\n<li>HCFCs<\/li>\n<li>HFCs<\/li>\n<li>Refrigerant blends<\/li>\n<\/ul>\n<p>The future commonly used refrigerants will be in the last two categories. Among the currently widely used ones are <a href=\"https:\/\/todayshomeowner.com\/hvac\/guides\/what-is-r134a\/\">R-134a<\/a>, R407C and R410A.<\/p>\n<h3 class=\"wp-block-heading\" id=\"h-amendments\">Amendments <\/h3>\n<p>The\u00a0Montreal Protocol\u00a0has undergone six Amendments:<\/p>\n<ul>\n<li><strong>London in 1990<\/strong><\/li>\n<li><strong>Copenhagen in 1992<\/strong><\/li>\n<li><strong>Vienna in 1995<\/strong><\/li>\n<li><strong>Montreal in 1997<\/strong><\/li>\n<li><strong>Beijing in 1999<\/strong><\/li>\n<li><strong>Kigali in 2016<\/strong><\/li>\n<\/ul>\n<p>The\u00a0<strong>Kigali Amendment<\/strong>\u00a0had agreed to reduce the use and production of HFCs as these refrigerants contribute to the greenhouse effect causing global warming.

For toxicity, the first character of the classification denotes the Class, which is either A or B; Class A denotes refrigerants with lower toxicity and Class B with higher toxicity.<\/p>\n<p>The subsequent one or two characters denote its flammability. There are three classifications and one subclass. Class 1 is for refrigerants that do not propagate a flame when tested as per standard; Class 2 is for lower flammability, and Class 3 is for highly flammable refrigerants. Class 2L is for refrigerants that burn very slowly.<\/p>\n<ul>\n<li>Examples of A1 refrigerants are R-22, R-407C, R-410A, R-507A, R-513B and R-515B.<\/li>\n<li>Examples of A2L refrigerants are R-32 and R-1234yf.<\/li>\n<li>Example of\u00a0A2 refrigerant is R-152A.<\/li>\n<li>Example of\u00a0A3 refrigerant is R-290.<\/li>\n<li>Example of B1 refrigerant is R-123.<\/li>\n<\/ul>\n<p>See the complete Ashrae Standard 34, which includes a list of refrigerants with their safety group and global warming potential, <a href=\"https:\/\/www.ashrae.org\/technical-resources\/bookstore\/ashrae-refrigeration-resources\" target=\"_blank\" rel=\"noreferrer noopener\">here<\/a>.<\/p>\n<h2 class=\"wp-block-heading\" id=\"h-recovery-recycling-and-reclaiming-of-refrigerants\"><strong>Recovery, Recycling, and Reclaiming of Refrigerants<\/strong><\/h2>\n<p>Laws have been passed to prevent the release of CFC refrigerants into the atmosphere. The steps taken are:<\/p>\n<h3 class=\"wp-block-heading\" id=\"h-recovery\"><strong>Recovery<\/strong><\/h3>\n<p>The act of removing the refrigerant from a system and storing it in an external container. No testing or processing is needed in any way.<\/p>\n<h3 class=\"wp-block-heading\" id=\"h-recycling\"><strong>Recycling<\/strong><\/h3>\n<p>Refrigerant is cleaned for reuse by oil separation and passes through devices such as core filter driers.
