Refrigeration gases, also known as refrigerants, are substances used in refrigeration systems to transfer heat and provide cooling. They undergo a continuous cycle of evaporation and condensation within the refrigeration system to extract heat from the surroundings and release it elsewhere.

In the past, chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) were commonly used as refrigerants due to their desirable properties. However, they were found to have detrimental effects on the ozone layer and contribute to global warming. As a result, international agreements such as the Montreal Protocol have phased out the production and use of many CFCs and HCFCs.

Today, the most widely used refrigerants are hydrofluorocarbons (HFCs) and hydrofluoroolefins (HFOs). HFCs do not deplete the ozone layer, but they have high global warming potential (GWP). HFOs are a new generation of refrigerants designed to have lower GWP, and they are considered more environmentally friendly alternatives to HFCs.

Some common refrigerants used today include:

1. R-134a: This is an HFC refrigerant commonly used in automotive air conditioning systems and other medium-temperature refrigeration applications.

2. R-410A: It is an HFC blend used in residential and commercial air conditioning systems as a replacement for R-22 (an HCFC), which is being phased out.

3. R-404A: This HFC blend is widely used in commercial refrigeration systems, such as supermarket freezers and refrigerated display cases.

4. R-32: This is an HFC refrigerant used in residential air conditioning systems due to its lower GWP compared to other HFCs.

5. R-1234yf: It is an HFO refrigerant used in automotive air conditioning systems as a replacement for R-134a, providing a lower GWP.

It's worth noting that refrigerant selection depends on the specific application, system requirements, environmental considerations, and regulations in different regions. Ongoing research and development efforts aim to discover and develop refrigerants with even lower environmental impact, such as natural refrigerants like ammonia (R-717), carbon dioxide (R-744), and hydrocarbons (R-290, R-600a).
