** Ice-cream freezer is defined in 10 CFR 431.62 as a commercial freezer that is designed to operate at or below -5 °F (-21 °C) and that the manufacturer designs, markets, or intends for the storing, displaying, or dispensing of ice cream.
Calculate the CEC for the entire case using Table 1 in ARI Standard 1200-2006 (incorporated by reference, see § 431.63 ), using the total refrigeration load and the weighted average saturated evaporator temperature. The CDEC for the entire case shall be the sum of the CEC, FEC, LEC, AEC, DEC, and PEC.
