Best Gas for AC in 2023 [ Which Gas is used in Refrigerator ]

As the summers approach, a considerable amount of people use air conditioners to keep them cool, calm, and relaxed. But often, we ignore the significance of refrigerant in an air conditioner. Refrigerant is commonly known as AC gas and is a substance used as a medium of heat transfer in air conditioners.

For the entire freezing process, the refrigerants move from the fluid state to a gaseous state across all working cycles. There are plenty of refrigerants available in the market, confusing you to choose the best one. Therefore, the ideal refrigerant has desirable thermodynamic properties, such as protection from harmful toxins and flammability and non-corrosive mechanical parts.

Types of Refrigerant [ AC gas ]

Refrigerants used in the air conditioners are as follows:

R-12 Refrigerant Gas
R-12 is an odorless CFC (Chloro Fluro Carbon) refrigerant that comes under white-color cylinders. The R-12 refrigerant gas is being used in liquid chillers, domestic freezers, ice freezers, and more. It is a highly popular air conditioner refrigerant for domestic use as it is non-toxic, non-explosive, and non-flammable. However, since it is a CFC (Chloro Fluro Carbon), it has a significant environmental effect and has the ability to deplete the ozone layer.

R-22 Refrigerant Gas
R-22 refrigerant, also known as HCFC-22 (Hydro Chloro Fluro Carbon), is a colorless gas that is extensively utilized in industries for chillers, machines and for delivering chilled water to several processes. The government has phased out this gas due to its ozone depletion potential and increased global warming contribution.

R-32 Refrigerant Gas
R-32 is a low global warming potential refrigerant HFC (Hydro Fluro Carbons) and is one of India’s most commonly used refrigerant gases. R-32 is currently used on a broad scale since R-32 can efficiently transfer heat and has the potential to reduce power consumption up to 10%. The R-32 gas has a lower concentration level and with absolutely no possibility of combustion.

R-134 Refrigerant Gas
R-134A is a non-flammable, non-toxic, and non-corrosive refrigerant that is utilized in several air conditioning applications. The R-134A is considered a suitable replacement of R-22 due to its properties, namely HFC (Hydro Fluro Carbon), no ozone depletion potential, and the minimal greenhouse effect. The demand for R-134A is gradually increasing because of its lower environmental impact.

R-290 Refrigerant Gas
The air conditioners equipped with R-290 combine HC (Hydro Carbon) properties and are deemed one of the most environment-friendly air conditioners since R290 is highly energy efficient. The R-290 is known to have zero ozone depletion potential along with minimal global warming effects. However, this refrigerant gas is highly flammable.

R-410A Refrigerant Gas
R-410A is a widely used refrigerant in air conditioners and is generally packed under rose color cylinders. This refrigerant gas resembles HFC’s properties (Hydro Fluro Carbons), having zero ozone depletion potential. The R-410A is introduced as an environment-friendly option in place of R-22 to be used in both commercial and residential air-conditioning products.

Best Refrigerant for Air Conditioner:

Several refrigerants have been employed in air conditioners, and each refrigerant carries its benefits. However, due to the increasing rules and regulations concerning global warming and ozone depletion potential, there has been a substantial shift in refrigerant usage.

This shift has resulted in utilizing refrigerants that have a minimal environmental impact. Therefore, out of the broad range of refrigerants, R-12, R-22, R-32, R-134A, R-290, and R-490A, the best and the most frequently used refrigerant is R-32 due to its zero ozone depletion potential.

The GWP (Global Warming Potential) is considerably less than other refrigerants available in the market or used in the air conditioners. Compared to the extensively used refrigerants such as R-490A and R-22, it significantly reduces electricity consumption, making it an ideal choice for air conditioners.

Final Thoughts

In case you care about conserving energy and global warming, you must opt for air conditioners with R-32. The more you would go with refrigerants with minimal and zero ozone potential and global warming, the more it would be utilized in the air conditioners, contributing less to global warming.
