2. 90pts. An insulated cool room is used to store tomatoes at 52F. Tomatoes are harvested from the tomato trees and brought to the cool room in bins containing 120lb of tomatoes each. 1,250 bins are harvested each day. Based on these storage conditions, what size refirigeration unit is required to cool the tomatoes from 77F to 54F in one day? CoolRoom The room has outside dimensions of 40ft long, 40ft wide and 15ft high. Each wall, celling and floor is 9 inches thick. Walls are insulated with 8.9 inches of polyurethane foam with a thermal resistance per inch of 6.25 (hA2F)/Btu-in covered with 0.05 -inch-thick sheet steel with a thermal resistance per inch of 0.2 (h- ft2 "F)/Btu-in. Neglect heat transfer through floor.
