Thoughts on Flammable 2, 2L, & 3 Refrigerants

Over the past few years the biggest concern when it came to refrigerants has been their Global Warming Potential. The higher the number the more damage that refrigerant could do to the environment. The Ozone problem has been fixed, more or less, due to the Montreal Protocol. In fact, just this month scientists announced that … Read more

After Recount, IEC Rules in Favor of Hydrocarbon Charge Increase

Flammable Refrigerants

Last month I wrote on the International Electrotechnical Commission (IEC) and their decision on rather or not to increase the allowed charge limit on hydrocarbon refrigerant applications. Before their decision was made the maximum approved amount was one-hundred and fifty grams under the IEC 60335-2-8 global standard. This proposed increase would have moved the one-hundred … Read more

IEC Declines a Hydrocarbon Charge Increase

Flammable Refrigerants

Last Friday the International Electrotechnical Commission (IEC) voted against increasing the charge limits on flammable hydrocarbon refrigerants such as propane (R-290) and isobutene (R-600a). The proposed changes aimed at increasing the global standard charge limit to five-hundred grams. Today, the International Standard known as IEC 60335-2-89 limits hydrocarbon A3 refrigerants at a charge of one-hundred … Read more

R-600a Isobutane Refrigerant Fact & Info Sheet

facts

In the very beginning of refrigerants and air conditioning there were a select few refrigerants used. 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

R-290 Propane Refrigerant Info & Fact Sheet

facts

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

Refrigerants: Environment In Trade for Safety?

Hello everyone! I hope your Labor Day is going well. We just got back from our city’s parade and I’ve got a few hours before our barbecue so I thought I’d take some time and get an article out there. I’m going to preface this article with the disclaimer that this is an opinion piece. … Read more

Hydrocarbon Refrigerants

The concept of refrigeration and air conditioning has been around for over one-hundred and fifty years. In the infancy of this industry there were a specific set of refrigerants used. These refrigerants were known as ‘natural refrigerants.’ Some of these natural refrigerants included some of the basic elements found today such as water, air, and … Read more
