coast of Maine | He will need 4 or 5 to get the space.What you want is usually a shuffle.One benefit to a refer is running on diesel versus electricity(now maybe same though).Pull down of warm product is your problem and the heat from warm earth beneath your concrete floor,I think your temp of ground is near 60 degrees in Florida.The volume of cooling is directly related to the tons of product and the speed you want it reduced to say 40 degrees ,a refer will need more defrost time than you can imagine if you put 20 tons in there at 85 degress it will never ever catch up to product to 45 degrees before product is ruined as then it makes more heat .The field heat in produce is astounding and the respiration heat from live product also adds cooling tonnage.Unless you are just pulling in pick up loads the cool bots wont do it.If product comes pre cooled yes they will work.You will need foam under the concrete.here in Maine you could just about get by but soil temps are low.I have seen some Amish low volume coolers here using just stored ice from the local lake,10 inch thick foam,tons of ice,gets them by but 42 degrees and just a horse pulled cart of product load.I used to store cabbage at 32 degrees,2 million lbs or so , two 40x100x16 coolers,ran 4 -10HP belt drive compressors,8 evaporators 4fans each,2 condensors 4 fans each,cabbage gives off even at 40 degrees -1 btu per lb per day,so 2,000,000 BTUs per day in respiration heat,so like having a 100,000 btu heater in there that you had to cool off 24/7.If going with feds /state rules FSMA you need cold.Good luck on your project.Getting a simple engineered load calculation will help. | |
