Origins of R410A Refrigerant

In an effort to replace harmful ozone destroying chemicals, the Honeywell Corporation started an ambitious research program in the late 1980s to develop environmentally friendlier refrigerants. The solution was found in 1991, when Honeywell announced to the world an efficient new refrigerant called AZ-20®. This amazing new chemical was later assigned the generic name of R-410A.  Years of effort with air conditioner manufacturer Carrier Corporation lead to the first commercially produced air conditioners using the new R-410A refrigerant in 1995. Carrier Corporation dubbed R-410A as used in their products under the brand name Puron. Over time many additional air conditioner and heat pump manufacturers got into the act and started developing products that use R-410A. For their efforts in finding ozone friendly alternatives, the EPA awarded both Carrier and Honeywell with the Stratospheric Ozone Protection Award in 1996.

R-410A is composed of two chemicals that have been blended to act as one in an air conditioning system. This consists of a blend of HFC-32 and HFC-125, both of which are exactly 50-50 by weight in the resulting refrigerant. This unique property of acting as a single uniform refrigerant is a huge reason for the success and industry acceptance of R-410A, as the first drop that goes into an air conditioning system is exactly the same as the last drop.

Honeywell's employees have worked long and hard over the years to find a viable solution to the problem of ozone depleting chemicals. Unfortunately many commercial cooling systems still use R-22 as their refrigerant - your local supermarket probably has a R-22 cooling system installed. Honeywell engineers work to prevent refrigerant leaks, and are always developing new non ozone depleting chemicals.

Their new AZ-50® refrigerant can be a replacement for large scale cooling systems still using R-22. Not only is AZ-50® safe for the ozone layer, it is also 6% more energy efficient than R-22, meaning it not only helps protect the environment, but also saves commercial operators like your local supermarket on their electricity costs.

Advantages of R410a


There are many excellent advantages afforded by R-410A, but these are only apparent when manufacturers of air conditioners redesign their products to take advantage of the R-410A's amazing new properties. All refrigerants work by capturing heat in one location and releasing it in another. R-410A does this much better and more efficiently than the refrigerant it replaces, R-22. Manufacturers actually found that because R-410A does its job better they don't need to add so much of it as they did with R-22, which in turn lead to smaller compressors and less copper tubing resulting in longer lasting air conditioners. The Honeywell Corporation continues to work closely with manufacturers to this day in an ongoing effort to optimize air conditioning systems to make them less expensive, more efficient, and more reliable. The advantages of these new more efficient air conditioners are too good to pass up, for manufacturers or consumers.
