When it comes to refrigerators, most of us might not know about their inner workings. For that, you need to know how a refrigerator works. To explain in the easiest format, a refrigerator works on a compressor and a gas usually called a refrigerant. A similar format is used in air conditioners, where a refrigerant gas is cooled using a compressor. Refrigerators simply use that cold air to cool the insides. If you want to know which gas used in refrigerator, we have a comprehensive guide here for you. Let us take a look.

Know which Gas used in Refrigerator


Which Gas Used in Refrigerator?

The majority of refrigerators use ChloroFluoroCarbons (CFCs) as their cooling agent. CFCs are effective because they have a very low boiling point, which allows them to evaporate quickly and cool the air inside the fridge. However, CFCs are also damaging to the ozone layer, so many countries have banned their use.

As a result, most manufacturers now use hydrofluorocarbons (HFCs) in their refrigerators. HFCs do not damage the ozone layer, but they are powerful greenhouse gases. As a result, some environmentalists have called for a switch to natural refrigerants such as ammonia or propane.

However, these substances can be dangerous if they leak, so any decision to switch to natural refrigerants should be made with caution.

Refrigerator Gas – Explained

The most common gas used in refrigerators is chlorofluorocarbon (CFC). CFCs were initially used because they do not contribute to stratospheric ozone depletion. However, it was later discovered that CFCs are also greenhouse gases, and their production and use is now regulated by the Montreal Protocol.

Other gases that are sometimes used in refrigerators include hydrofluorocarbons (HFCs) and hydrocarbons. HFCs do not deplete the ozone layer, but they are powerful greenhouse gases. Hydrocarbons are flammable, so they must be used with care. When used properly, however, they can be an effective and safe alternative to CFCs and HFCs.

The gas most commonly used in refrigerators is Freon. Freon is a chlorofluorocarbon (CFC), which means that it contains chlorine, fluorine, and carbon. CFCs are highly stable, meaning that they do not react easily with other molecules.

This stability makes them ideal for use in refrigerators, as they do not cause the build-up of ice on the inside of the fridge. In addition, CFCs are also non-toxic and non-flammable, making them safe to use in the home.

However, due to their stability, CFCs are also responsible for the depletion of the ozone layer. As a result, their use is being phased out in favor of more environmentally friendly alternatives.

Frequently Asked Questions (FAQs)

Which gas is used for refrigeration?

There are a variety of gases that can be used for refrigeration, but the most common is Freon. Freon is a colorless, odorless gas that is non-flammable and non-toxic. It is also relatively inexpensive and readily available. As a result, it has become the standard choice for most commercial and industrial refrigeration applications. However, Freon is not without its drawbacks. It is a greenhouse gas, meaning that it contributes to global warming.

Which gas is used in refrigerators and AC?

The most common type of refrigerant used in household appliances is chlorofluorocarbon (CFC). CFCs were once widely used because they are non-toxic, non-flammable, and cheap to produce. However, CFCs are also powerful greenhouse gases, and their release into the atmosphere has been linked to climate change. As a result, the production of CFCs was banned by the Montreal Protocol in 1987. Today, most refrigerators and air conditioners use hydrochlorofluorocarbons (HCFCs), which are less harmful to the environment but still contribute to climate change.


Refrigerators are common household appliances that use a refrigerant gas to keep food and other items cool. When the refrigerator is turned on, the refrigerant gas is compressed, causing it to become very cold. The cold refrigerant gas then flows through a series of coils in the fridge, cooling the air inside. As the air inside the fridge cools, it causes the food to become colder as well. When the refrigerator is turned off, the process is reversed and the refrigerant gas expands, becoming warm once again.

We hope we answered your question about what gas is used in refrigerators.
