What is Refrigerants and what is it types
                     What is Refrigerants and 
what is it types?
What is Refrigerant?
● Refrigerant is a substance used in cooling applications, it helps 
to transfer heat from one place to another.
● We can find refrigerant either in the form of gas or in the form of 
liquid. Without Chiller gas, the freezing and Air Conditioning 
applications will not work.
● It is an important compound plays a huge role in cooling your 
home.
What is Refrigerant?
● By assorted with compressor and evaporator, the refrigerant 
takes in heat present in the environment and produce chillness.
What is Refrigerant?
● Does not everyone know what exactly happens inside the 
refrigerator or other cooling applications? 
The working of refrigerant is simple in starting it absorbs the 
heat in the environment and it transforms a low-pressure gas 
produced by the compressor into liquid.
What is Refrigerant?
● The components then transfer the refrigerant outside. This is 
where the fan moves hot air over the coils and exhausts it to 
the exterior. 
● Refrigerants then cools down the gas and passes to the cool 
coil it finally resulted in producing the cold air. 
What is Refrigerant?
Chlorofluorocarbons
● Mostly Chlorofluorocarbons found in fridges and freezers and 
this gas contributes more in the greenhouse effect. 
● Hence, it was banned in 1995.  The new law passed in 1995 
said that buying and selling CFC is illegal. CFC is then 
replaced by R134. 
What is Refrigerant?
R134A
● R134  does not cause a greenhouse effect as like as R12. This 
gas is found in nearly 40% of the freezers and fridges. In 2011 
Some countries ban using R134A in new cars. 
What is Refrigerant?
Hydrochlorofluorocarbons
● Damage caused by Hydrochlorofluorocarbons to the 
environment is comparatively less than chlorofluorocarbons. 
● We found this gas in window air conditioners. In future the use 
of Hydrochlorofluorocarbons may get decrease due to the rise 
in the service cost.
What is Refrigerant?
R140A
● Due to cost-effectiveness and better-quality, people do prefer 
this refrigerant in Air Conditioning applications. 
● It causes more greenhouse effect than Carbon Dioxide. This 
gas is mostly used in a split system air conditioner.
