How to design refrigerators/fridges?

Hi all,
I am investigating the designs of household refrigerators and especially enhancement of their efficiency. Is there someone can help me on this topic and where I can find relevant documents ?

hi n n new, have you got a bad s s s st stu stutt er ?

i really do not understand what you meant with "s s s st stu stutt er" !

you dont understand ? , I dont understand why you bothered to write the same thread 5 times ,
dose that answer your question ? sedgy,

try c***ys or c***t electrical stores,panasonic do an energy efficient fridge but its £1200 unfortunatly the mrs wouldnt let me but it!!

newbieeng, this is going to be a challenge as there is NO efficient fridges (that i have come across) that are on the market today. Sure, some select camping chillers are fine, as they have to be for limited power supply, but when you have mains supply 24 hours/day, the situation changes. All bells and whistles on fridges now and no Insulation to speak of. Two steps for efficiency... more insulation and get the condenser back out in the open:rolleyes:, the way it was many years ago. Ah, don't think i need to repeat this post 5 times;). Sedgy, i spilt my cuppa when i read your reply:D.. Mike.

thanks you all for your interest,
but i need information rather than comments. I have written the question 5 times under different topics to get the answer quickly. what is the problem with it? anyway... thanks again.

and also there must be an error here. i did not write my thread here 5 times. it is not relevant with me.

No you didn't....you posted it 5 times in different threads and a Moderator merged them all together. Posting once is sufficient.

ok Frank. next time i will do it one

What investigation have you done so far into this subject, what are your conclusions to date?

What is your involvement here, do you manufacture them or is this a college question?

try lg linear compressors

I am about begining of a research and development project that is releated to characterization of refrigerator and refrigeration on determined scenarios for household fridges. My aim is to observe refrigerant's thermodynamic behaviours and to determine design parameters to equipment like evaporator, condenser. Observing refrigerant behaviour is to difficult while refrigerator cycle works. First target is observing its thermodyanmic behaviour while the cycle works on a household fridge. After it, of course if we can success it, we determine our equipment's situation on the fridge. For instance, after observation we want to say something like that "Yes this evaporaator is too big for our refrigerator, we must change it with small one." And we want to base this on a systematic, a method.
