Intern Experiments - 3

hii frnz... moving ahead.. we have done a lot of experiments by now ... the problem if properly understood says that the product shows unusually high pull force if the RC/Fc door is opened before the next opening .....hence the culprit id the opening of the door.
we have started with understanding the flow of air inside the refrigerator when the door is opened... for this we tried to make model of a ref whose side walls were made of perspex walls and witht the help of a smoke machine tried to see the flow.. .. unfortunately the flow was too turbulent in FC and the flow was thus not visible properly... although we got some hints as too what can be the most influential causes behind the phenomena.. they can be the turning offf of the fan and the slamming of the door...
our next set of experiments are based on difffernetiating there effects on the pressure falll..
there has been a lot of previous work on this.. and this problem is faced by all leading refrigerator makers.....a vacuum valve is the latest addition by companies....

Resuming the details about my stay here at whirlpool i have also been given a side project to design a utility box which can be placed on the top of the refrigerator , where the things which are generally kept in a households can be kept nicely and efficiently by using the top space of ref.Whirlpool india has previously launched a box which is kept under the refrigerator and can be used to keep vegeatables which are generally not kept inside the refrigerator ex potatoes ,onions etc.
I am directed to work on the similar terms.
As about the first project we have started on with DOE(design of experiment.. thats what they call experiments here).We have performed a no of DOE's to understand the problem.
In the coming posts will let you know about the what are the performed and planned DOE
's...

Intern Experiments - 1

hi folks ..i have started with my practical training here in pune at whirlpool of india limited. I am sorry that i was unable to write entry last week.Its very difficult to access internet here due to long working hours and strictness in the company for using i-net.Still i would try to write atleast one per week.I have been assigned two projects here.
first deals with reducing the pull force of the refrigerator door in case of double door (global no frost) model product.Description of my project in brief is as follows.When the refrigerator is in on cyle that is when the compressor is running ,if we open the freezer compartment(FC) and then slam it and then try to open the refrigerator compartment(RC) in quick succession of around 10 s interval, then the pull force required to pull the RC door gets increased.
will post the details of the second soon....
