摘要：A transient model of food freezing process in cold store was developed to investigate operation strategy, which was further optimized to minimize the energy consumption. Current food freezing control was based on freezing time which was controlled by airflow distribution, including temperature and velocity in common air-blast cooler. The simulation was conducted on the example of the experimental cold store, considering heat and mass transfer between air, food products and other components. Evaporation temperature of refrigeration system and fan speed of air coolers were chosen as the control variable. Results show that in any specific case of food freezing, an optimal operation strategy can be found to satisfy the freezing time requirement and minimize the energy consumption.
