By now, you probably know about the environmental concerns related to global warming and ozone layer depletion. While a lot of factors are to blame, the heating and cooling industry has been responsible to quite some extent. Some of the common synthetic refrigerants are highly damaging to the environment, including HFCs and CFCs. There has been a push towards better choices of natural refrigerants, and if the trends are anything to go by, the use of HFCs will be banned in most continents in years to come. So, what are these natural refrigerants? Below are some of the quick facts you need to know.
What are natural refrigerants?
As the name suggests, natural refrigerants are “naturally” and non-synthetic and replace HFCs and other options in the cooling systems. Some of the best natural refrigerants include carbon dioxide, hydrocarbons like butane and propane, and ammonia. All of these are particularly useful in certain sectors, and experts believe that this can be the thing for the future. All of the natural refrigerants listed here are ozone-friendly, which means these don’t deplete the ozone layer. There are a bunch of other technologies that are being used, so as to reduce the concerns related to the environment, and if industry experts are to be believed, co2 and hydrocarbons are the refrigerants of the future in more ways than one.
More on CO2 and ammonia
You might be surprised to know that CO2 is a natural refrigerant, given that the emissions of carbo dioxide is one of the major planet concerns. In the same way, ammonia is known to be highly toxic. If you go by numbers, carbon dioxide has a GWP or Global Warming Potential of 1, which is extremely low compared to some of the refrigerants that have the number in thousands. The rating of carbon dioxide for ODP or Ozone Depletion Potential is Zero, which is quite what you would expect from a refrigerant. On the other hand, ammonia has an ODP and GWP rating of 0. While ammonia is still produced synthetically, it is still a natural refrigerant. In the cooling and refrigeration industry, ammonia and CO2 has been used effectively, safely and wide for a number of applications.
