Which gas is used in refrigerator now a days for cooling

Are you interested to know about the concept of working of the refrigerator, and know about refrigerant gases, this article may help.πŸ˜ƒ

Gases used in refrigerators feron

Which gas is used in domestic refrigerators?

• Chlorofluorocarbon (CFC),
• Hydrochlorofluorocarbon (HCFC),
• Hydrofluorocarbon (HFC),
• Perfluorocarbon (PFC),
• R-134a tetrafluoroethane
• Blends made from ammonia and carbon dioxide.

These refrigerators are used in domestic refrigerators.
Note: These gases are listed according to class 9,10,11,12.

Which gas is used in modern refrigerators?

Modern refrigerators also use these gases mentioned above but basically, gas used in developed countries are:

HFC-134a (1,1,1,2-Tetrafluoroethane)

It does not deplete the ozone layer. The main refrigerants now used in these countries are R-600a or isobutane. It's getting more in countries like Europe.
These gases not only saves our environment from global warming and ozone layer depletion. But it increases the energy efficiency of the refrigerator.

What are refrigerant gases?

Gases which are used in refrigerators to cool the materials in the refrigerator are known as refrigerant gases. It's not necessary only the gases in refrigerators can be called refrigerant materials or gases. Moreover these gases HFC-134a (1,1,1,2-tetrafluoroethane), (CFC),(HFC) and all are known by these names.
These gases are compressed under high pressure. These gases are present in liquid form inside the refrigerant gas cylinder.

You may have seen on the backside of the refrigerator there is a black cylinder of gas.

These gases are highly used in refrigerators and air conditioners. But these gases are very harmful to the environment. You might have read in class 9th or 10th.

How many types of refrigerant gases?

R-22 refrigerant gas

There are many types of refrigerant gases because refrigerant gases don't need to have a certain type. Each has which comprises all the property of the refrigerant gas is a type of refrigerant gas.

But generally, two refrigerant gases are taken into consideration and comprise hydrofluorocarbon refrigerants, difluoromethane, and pentafluoroethane.

These gases are:

•Chlorofluorocarbons (CFCs), 
•Hydrochlorofluorocarbons (HCFCs), 
•Hydrofluorocarbons (HFCs)

Working of Refrigerator :

The working system of a refrigerator is quite simple.
The refrigerant which is present in the expansion valve of the refrigerator just enters the evaporator coils and after that, it starts absorbing heat from the food stored in the refrigerator. 
After it completely works there, the refrigerant is then sent to come pressor in a gaseous form where it is compressed into a high pressure, and after that, it enters the condenser coils.

As we know that the use of a refrigerator is to keep the food cool and safe, so the role of refrigerant gas or we can say coolant is very important here for the entire functioning and process of 
Refrigerant is used in the refrigerator since the beginning of this as a basic need and has not changed from till now. The gases used as refrigerant or coolant has changed from time to time
like Chlorofluorocarbons,
hydrofluorocarbons, etc. but their 
usage is still the same, as a refrigerant.

Isn’t the process quite simple?

How CFC gas depletes the ozone layer?

The gases which are present in the refrigerator, automobile air conditioning, air conditioner, and propellant spray are leading our environment to global warming.

The CFC gas breaks down the molecules of the ozone layer. As the Ozone Layer is made up of trioxygen O3. It reduces the capacity of ozone by the absorption of ultraviolet rays of the Sun. This process is also known as ozone depletion.

Which home appliances pollute our environment?

Well, older refrigerators pollute our environment ♻️ a lot. The old refrigerators contain higher CFC and HFC gases in the compressor. So it pollutes our environment, very much.

Air conditioners also contain these gases. So, it can be said that air conditioners are also a factor in the increase of global warming.

Ways to save nature from refrigerant gases. First, of all reduce the use of the refrigerator.

Reduction of CFC in the refrigerant gases.

Alternatively, HFC-134a (1,1,1,2-Tetrafluoroethane) could be used in refrigerators and air conditioning.

How to reduce the use of the refrigerator.

Nowadays, a part of our life is dependent on modern appliances. The refrigerator is one of the most important home appliances. Reducing its users can't be there. But to save our environment it could be a major step.

Frequently Asked Questions 

What is average life of a refrigerator?

Well, it varies from the condition it is kept. But basically, it is 13 years Aproxx of a newer refrigerator.

What happens when the fridge runs out of gas?

You fell an unpleasant smell from the food. The food gets moist and the leaves seem a little bit black.

How much does it cost to fill gas in the refrigerator?

Well, the average price is 10$. In India, it costs between 600₹-1000₹. It also varies from the refrigerant gas to fill.

What does Feron gas smell like?

All refrigerant gases including Feron and r-22 smell unpleasant. If you have ever kept a refrigerator for defrosting then the smell is quite similar to that
