FAQs on Unsaturated Hydrocarbon Refrigerant, Refrigeration and Air Conditioning, Mechanical Engineering, GATE Video Lecture
| 1. What is an unsaturated hydrocarbon refrigerant? |  |
Ans. An unsaturated hydrocarbon refrigerant refers to a type of refrigerant that contains carbon-carbon double or triple bonds in its molecular structure. These refrigerants are commonly used in refrigeration and air conditioning systems due to their low environmental impact and high thermodynamic efficiency.
| 2. How does an unsaturated hydrocarbon refrigerant differ from a saturated hydrocarbon refrigerant? | |
Ans. The main difference between unsaturated and saturated hydrocarbon refrigerants lies in their molecular structure. Unsaturated hydrocarbon refrigerants contain carbon-carbon double or triple bonds, while saturated hydrocarbon refrigerants only contain carbon-carbon single bonds. This structural difference affects their chemical and physical properties, such as boiling point and heat transfer capabilities.
| 3. What are the advantages of using unsaturated hydrocarbon refrigerants in refrigeration and air conditioning systems? | |
Ans. Unsaturated hydrocarbon refrigerants offer several advantages in refrigeration and air conditioning systems. These include higher thermodynamic efficiency, which leads to lower energy consumption and operating costs. They also have low global warming potential (GWP) and ozone depletion potential (ODP), making them more environmentally friendly compared to traditional refrigerants.
| 4. Are there any safety concerns associated with using unsaturated hydrocarbon refrigerants? | |
Ans. While unsaturated hydrocarbon refrigerants have gained popularity for their environmental benefits, they do pose some safety concerns. These refrigerants are highly flammable and require careful handling and storage to prevent fire hazards. It is essential to follow proper safety protocols, including using suitable equipment and ensuring adequate ventilation when working with unsaturated hydrocarbon refrigerants.
| 5. How can the use of unsaturated hydrocarbon refrigerants contribute to sustainable refrigeration and air conditioning practices? | |
Ans. The use of unsaturated hydrocarbon refrigerants aligns with sustainable refrigeration and air conditioning practices in multiple ways. These refrigerants have low environmental impact, as they have minimal or no contribution to ozone depletion and global warming. Additionally, their high thermodynamic efficiency results in reduced energy consumption, leading to lower greenhouse gas emissions and overall environmental footprint.
Text Transcript from Video
my dear so in this video I am going to
share with you how we can find out the
value of the chemical name for any
unsaturated hydrocarbon and we have an
example of here
unsaturated hydrocarbon as 1150 our 1150
now how I can convert and how I can get
chemical name for this represent for
this again we need to have 3 need to go
through these steps I must share with
you but yes you need to concern you need
to grab the concept behind this those
formulas are R 1 M minus 1 and plus 1 B
again M plus P plus Q is equal to 2 m
again CM h an FP c lq all three formulas
all 3 steps we need to follow to convert
to get the chemical name for these are
1150 sounds good so let's just let's get
started how we can do it just compare
start comparing 1 1 you don't need to do
anything with this one first term second
term what we got M minus 1 is equal to 1
if we will simplify M is equal to 2
third term n plus 1 is equal to 5 it
will simplify n is equal to 4 fourth
term P is equal to 0 don't need to
simplify because already its value is 0
now if I will put all values what would
be missing Q then to fulfill this I need
to find out the value of Q for this we
have a formula that is given below in
the second step that is n plus P plus T
equal to 2m so just put values of others
n is equal to 4 P is equal to 0 Q is
equal to these and 2m 2 into 2 well
simplify as you know Q is equal to 0
that means
what I have to do I have to put all
values in this equation all day so how I
can put this M in the place of M I have
to write 2 in the place of n I have to
write 4 and in the place of p 0 and C L
0 that means C 2 H 4
look at this represent my dear this
definition also clue is this FN is also
chlorine-free
that means this is amazing isn't it my
dear so that means this is a
chlorine-free that means this is also
Aiko friendly represent because this is
chlorine-free
all right so I hope you understand the
concept of finding out the chemical name
of the refrigerant and how it is helpful
in the complete examination basically we
need to find out its chemical name maybe
sometimes they provide us some tricky
quotient that means they ask that this
is the affinity present or not for that
case you have to find out or you can
remember also but I'll suggest you need
to know the long step at least if you
will get confused in the examination
hall then you can solve the problem
itself and find out the right answer
that's why you can mark the right answer
in the complete examination all right so
I hope the you understand the basic
concept behind this to solve the
question all right so thanks for
watching and see you soon in my next
video bye bye see you soon my dear
