Not Sure What Gas Your HVAC Needs?

What Are the Different Types of Commercial Refrigeration Gasses?

A commercial refrigeration gas is a chemical used in freezers, refrigerators, air conditioners, and HVAC systems. These have low evaporation points which are condensed under pressure to cool the surrounding air. Through a technique of continuously evaporating and condensing gasses, heat is taken out of the air, and the temperature within a space is reduced. Different kinds of refrigerant gases are hydrochlorofluorocarbon, chlorofluorocarbon, hydrofluorocarbon, perfluorocarbon, and mixtures made from carbon dioxide and ammonia.

The first refrigerators from the 1800s to the 1920s mainly used toxic gases like ammonia, methyl chloride, and sulphur dioxide. Sadly, they did leak occasionally, thus leading to several deaths – this in turn lead to the refrigeration industry putting in a concerted effort to use a safer refrigerant. The result was a chlorofluorocarbon gas – this is a combination of chlorine, carbons, and fluorine. This was colorless, odorless, non-toxic, and non-flammable, and soon became the gas mostly used.

Some have replaced CFC with HCFC; this is a combination chlorine, hydrogen, carbon, and fluorine. These come with a shorter life span when exposed to the air, which results in less damage done to the ozone. Another popular gas is HFC; this has no chlorine and is said to have zero effect upon the ozone. PFCs are man-made; they are composed of just fluorine and carbon ions and are considered ozone friendly too. These replacements still cause environmental concerns if they happen to leak, because they are thought to be greenhouse gases and could contribute to climate changes.

Several industrial applications have gone back to natural gas, like a blend of ammonia and carbon dioxide, and research carries on to find a more environmentally friendly ways to meet these needs. Refrigeration systems must be built to certain standards, and commercial ones are subject to very strict monitoring. Most countries, like UK, Canada, members of the EU, Japan, New Zealand, Australia, and the U.S. require technicians that work on any units that use refrigerant gas have to be certified and licensed.
