Increased awareness about global warming and the reduction of greenhouse gases is of global importance. In accordance to the Montreal protocol, refrigeration and air-conditioning manufacturers in the United States have phased out ozone-depleting, chlorine-based refrigerants as of January 2010.

Common hydrochlorofluorocarbon (HCFC) refrigerants like R-22 will shift to hydrofluorocarbon (HFC) refrigerants like R-410A for air conditioning and R-404A for refrigeration over the next two years to prevent further ozone-depletion.

Emerson Climate Technologies is helping customers go through this phase by switching to these new and more environmentally friendly refrigerants as right now.

Scientists believe that global warming is a result of greenhouse gases like carbon dioxide produced by the combustion of fossil fuels in electrical generation and transportation. Air conditioning and refrigeration systems consume energy which if utilized inefficiently, will result to higher carbon dioxide production.

To avert this effect, the development of more energy-efficient and eco-friendly refrigerants takes the forefront in this industry. After thoroughly researching and identifying the most eco-friendly alternative, the HVAC/R industry is recommending more efficient refrigerants like R-410A for air conditioning and R-404A for refrigeration to replace the HCFC-based R-22.

Both R-410A and R-404-A use HFC to eliminate ozone depletion potential; and have also been tested to be safe, environmentally friendly, more energy efficient and nonflammable. Ultimately, both R-410A and R-404A users will experience a considerable reduction in their overall energy consumption and carbon dioxide emissions.
