Description
A model of a refrigerated display cabinet for chilled liquid foods was developed and validated against measured data for pull-down of the product from ambient temperatures to storage conditions. The model includes consideration of refrigeration system performance, air distribution throughout the cabinet, product cooling, and energy use. It was found that the model accurately predicted the temperature and energy consumption during pull-down if a 68% correction factor was applied to the compressor manufacturer’s isentropic efficiency data. The model can be used to evaluate alternative cabinet designs in terms of pull-down rate and energy consumption, as part of an accelerated development program that reduces prototyping work.
