All around the globe at this precise moment in time there are millions of vehicles on the roads, coaches , Trucks , vans , cars and buses and not every country has the MOT system like the UK, not all vehicles are in great shape and what is worrying about this is in these vehicles there will be air conditioning equipment parts, a gas / liquid of a toxic chemical compound that is damaging to our ozone layer. 

 Refrigerants come in three types and all are toxic and damaging to our ozone layer and the environment we live in, HCFCs or Hydrogenated Chlorofluorocarbon refrigerant is its correct name, HFCs  known as Hydrogenated fluorocarbon refrigerants, and the third one of these refrigerants is called  Chlorofluorocarbon refrigerant also known as CFCs. 

 Chlorofluorocarbon refrigerants or CFCs is made up of chlorine , fluorine and carbon, This is considered to be one of the most dangerous of the three gasses as it contains a very high amount of chlorine and is the most damaging and toxic to our environment and particular our planets ozone layer, This is not a gas you would like to escape from its shackles to create havoc. 

HCFCs is the second one of the refrigerants I am looking in to, This one is a cocktail of  fluorine , carbon and chlorine hydrogen and because of the lower amounts of chlorine that are in its make up this one is supposedly not as damaging as the previous, to give HCFCs its correct name it is called Hydrogenated chlorofluorocarbon refrigerants. 

 Hydrogenated fluorocarbon refrigerants or also known as HFCs  is a combination of hydrogen fluorine and carbon as this one does not use the chlorine atom it is considered and I use the term loosely  to be the least damaging and toxic of the three to our environment and ozone. 

There are two types of chemical compounds in refrigerant gasses /liquids the first is Zeotropes, and the other is known as Azeotropes. Zeotropes contain three different forms of chemical compounds and each compound once mixed together manages to keep its own individual properties,   Azeotrpes on the other hand are a mix of two forms of compounds and when combined they will act as a single refrigerant. 

All of the air conditioning units I have looked at all have two things in common, the first is they all absorb heat very well and do there jobs as they were intended to do. The second thing they have in common is that they are all toxic and will cause havoc to our ecosystem and the ozone layer if they escaped, Sadly they also do this job very well though it was more than likely when they were mixed this side effect was unknown.
