Energy Calculation• Winery crushes 300 tons/year• 300 tons x 1
ton refrig = 15 tons of refrigeration
year 20 tons grapes
• 300 tons x 175 gal x 4 BTU x 24 hr x tonR = t l h d 288
000BTUyear ton gal hr day 288,000BTU
= 17.5 tons refrigeration
• Barrel room and case storage air cooling – 1 ton refrigeration
/ 600 ft2– so if we have a 2400ft2 room:
• 1 tonR x 2400 ft2 = 4 tonR600ft2
Cooling for the small winery• Small batch size – surface area
vs. fermentation
heat. Use slow fermentation yeast.• Cooling with water –
assuming water is cold and
waste water is not an issue.• Night time temperature drop –
useful in someNight time temperature drop useful in some
areas (need outside bonded area)• Harvest time (early morning
vs. late afternoon.• Some areas of the country water can be
added
therefore ice can be added. (short term fix)• Cold rooms or
refrigerated trucks for temporary
cooling.• Dry ice can be added but is expensive and
typically a short term fix.
