Hi menezes2010
u should calculate the heat load to get the cooling capacity u need 4 this room, so u need 2 determine the products that u want 2 store in this cold room, the insulation type & thickness, the no of people working in it, the ligthning load, infilteration load. after all these estimations u get the capacity in Kw, TOR or Hp what ever it is u buy a refrigeration machine with this capacity & it's already attached with the corresponding evaporator & all other parts.
I think u didn't use the right forum, u should use Technical Discussion forum instead of Refrigeration book u've used.
Thank u
Sonic

to make it easy 4 u'
go to helpman site, download the software for rer load calc
for room capacity use 40 to 50% of room volume and if you know daily intake y must enter the value otherwise you can estimate 10 to 20% of of room capacity
