IIR document

A model to evaluate refrigerated cabinet designs for energy efficiency.

Author(s) : LOVE R. J., CLELAND D. J.

Summary

A model of a refrigerated display cabinet for chilled liquid foods was developed and validated against measured data for pulldown of the product from ambient temperatures to the storage conditions. The model includes consideration of refrigeration system performance, air distribution throughout the cabinet, product cooling, and energy use. It was found that a simple two dimensional model was not able to accurately predict the spread of temperatures in the cabinet. However a modified version of the model that divides the cabinet width into three zones was able to improve the predictions of the distribution of temperatures within the cabinet. The model can be used to evaluate alternative cabinet designs in terms of pulldown rate and energy consumption, as part of an accelerated development program that reduces prototyping work.
