Help regarding cold store design!
Dear All,
I need Help regarding the design of a cold store for potatoes. (Normal cooling not frozen)
cooling capacity is 50 TR or 175 KW
now i need to select the whole system and basically i need to know if it is done through softwares or from
catalogues.
a water cooled condenser is needed and water temperature is 27 C so condenser temperature is around 35
potatoes temperature around 0-2 C so evaporator temp. is -5 C (correct me if wrong)
i guess a screw compressor is fine for the specified cooling capacity
now what are the criteria or the basic procedures to select the cycle components; evaporator, compressor, condenser and XV and is their any constrain for refrigerant used. i guess any refrigerant is fine.
thanks in advance

Bulk potato cooling needs air flow from below the pile. The refrigeration idea you have is about right but good air distribution is very important. Go to this web site for one source. http://www.gov.mb.ca/agriculture/cro.../bda04s06.html

0-2 C is to small... Temperature around must be +3...+4 C for a table potatoes rh 95%, and correspondingly evaporating temperature will be near -2...-1 C.

Potatoe stores need CO 2 monitoring and lots of fresh air. They can go from potatoes to mush overnight if you don't have monitoring and fresh air flushing. Been there done that.
