摘要：

Dynamic mathematical models of two thermal storage systems used in the food industry to produce chilled water are presented; an ice-bank system and a holding tank system, The variability of the refrigeration demand with time was taken into account in the model. A zoned approach using mass and energy balances was applied. Hear transfer phenomena in the evaporator were modelled using empirical correlations. The experimental validation of the mathematical models on an ice-bank system at pilot plant scale, and a centralized refrigeration system with a holding tank in a winery, showed accurate prediction, Simple models are adequate to predict the dynamic behaviour of these refrigeration systems under variable heat loads, (C) 1999 Elsevier Science Ltd and IIR.
