As we all know, there is no perfect refrigerant. Each one has its own individual upsides and downsides. It could have a great efficiency but also end up being very flammable. Or, it could be non-flammable and non-toxic but have very high Global Warming Potential. The point I’m making here is that there isn’t a … Read more

These refrigerants occurred naturally within our environment and were known as natural refrigerants. These included ammonia, carbon dioxide, water, and oxygen. Among these natural refrigerants under a subset category are what’s known as hydrocarbon refrigerants. Some examples of hydrocarbon … Read more
Natural refrigerants and hydrocarbons, such as propane, are some of the cleanest and environmentally friendly options out there for air conditioning and refrigeration. However, over the past century America has had very little use of natural refrigerants. Instead, we have opted for synthetic refrigerants such as CFCs, HCFCs, HFCs, and now HFOs. While these synthetic … Read more
I am all for getting back to our roots. So many times nowadays it seems that we over complicate things. The same thing can be said when it comes to refrigerants.
