Component Analysis For R134a Domestic Refrgerator
Hello everyone,
I am an under graduate Mechanical Engineering student, and right now working in a project, for which its required that i will have to assemble all the components of the refrigerator R134a based, since i am very much new to this field, i dont have much practical experience, i need your help in component analysis and component matching. It would be very helpful for me if u can tell me various sites and e-books related to it.In short How to start the assembling of a refrigerator?..Thanks for your Valuable time.

Re: Component Analysis For R134a Domestic Refrgerator
Thanks a lot for inputs Taz..I am aware of the basics, i just need help in the balancing of the system, that is what type of compressor is suited to what what type condensing unit, dimension of the capillary tube, in short I have to assemble the refrigerator and hence need to have knowledge about balancing of the system.

You have plenty of tools for your needs there, and by studying every tool you should learn more about selection and balancing of refrigeration circuit components.

Re: Component Analysis For R134a Domestic Refrgerator
For your calculation you need more information.
What is entering temperature of water?
What is desired temperature of Ice.
What is desired time for ice production.
What is heat gain in freezer from surrounding.
What is heat gain in freezer from fan motor and lighting.
What is Ice form
What is air circulation heat gain from opening freezer

Re: Component Analysis For R134a Domestic Refrgerator
HI NIKE GOOOD AFTER OON
THANKS FOR INTREST
What is entering temperature of water?
Ans= 20c
What is desired temperature of Ice.
Ans= -18c
What is desired time for ice production.
Ans =24/hr
What is heat gain in freezer from surrounding.
ans= i can't understand it explain it details (ambiant temp)(43c)
What is heat gain in freezer from fan motor and lighting.
ans=there is no fan and light in freezer (dircet coolrefrigerator)
What is Ice form
Ans= i can't understand it explain it in details
What is air circulation heat gain from opening freezer
Ans= i can't understand it explain it in details
Thanks and best regards

Re: Component Analysis For R134a Domestic Refrgerator
That is calculation of heat ingress from surrounding in freezer at designed ambient and freezer temperature.
Because the freezer is in surrounding that is at higher temperature than his internal temperature and because your insulation is not perfect you must add that heat to total cooling load.
That mean that you need to calculate how much heat is coming from surrounding thru freezer insulation panels at your operating temperature and highest ambient temperature.
What is heat gain in freezer from fan motor and lighting.
ans=there is no fan and light in freezer (dircet coolrefrigerator)
What is Ice form
Ans= i can't understand it explain it in details
What is air circulation heat gain from opening freezer
Ans= i can't understand it explain it in details
Do you have any tutor (teacher, older engineer) in your company?
I ask this, because these questions you should ask him, and he should be able to explain them to you in much easier way and at concrete examples.
Unless, he is deaf, blind, dumb and speaks Hungarian language.

Re: Component Analysis For R134a Domestic Refrgerator
Dear Jahangir, my impression is that your knowledge about physics and other disciplines needed in this industry is not suitable for tasks you are challenged with.
It is obvious that you don't have basic knowledge how to convert one unit system to other unit system and that is something what any engineer need to know when you wake him in middle of night.
Today, with help of internet, there is no excuse to some engineer that he could not convert any unit in other unit, no matter of his expertize.
It is just matter of basic engineer knowledge as it is calculation as 2+2=4.
Don't be dejected by this taught, but I think that you need serious tutoring.Last edited by nike123; 02-05-2008 at 10:59 PM.

Re: Component Analysis For R134a Domestic Refrgerator
HI GOOD MORNING MR.NIKE
I'M VERY HAPPY TO SEE YOUR COMMENTS ABOUT
I'M AGREE ABOUT WHAT U SAY
BUT ONE THING REMEMBER IF U NOW THAT HOW TO CALCULATE THE
BTU/hr?
why u don't tell us
i'm now the basic of refrigeration for your kind information if u any no#
(cell no#)to call i 'll ans u on the spot about basic
now guide me how to find the btu/hr
this is my last request to u
please understand my problem except telling me to hair any teacher
thanks for your kindness
