Ok guys I'm back with a new dilema.

I have 85kg of peaches at 18C and I wish to freeze them at -25C. I'm working on about 12hrs pull down time. My ambient is 36 and wish to condense at 45C.

Now as far as my calcs go I'm looking at 824Watts to cool in 12 hrs.


AM I RIGHT TO THIS POINT?



Now If I wish to size a system how do I go about it?


If I'm using R404a am I right by going straight to a capillary selection table and selecting 2m at 1.1mm dia?


Then I sized the compressor to 825watts, A Maneurope LTZ22JE.

Stop me guys if i'm off in the wrong direction.

How do I size my Evap and Condenser? And do I need to take into account the size of my cabinet as well.

Where do I find the info I need to size my coils? Oh once I size this I will then need to size my evap and condenser fans.

How much info do I need to be able to build a prototype?



This is just a theoredical exercise.








Thanks for the insight guys.
