Abstract Long-term refrigeration of frozen pork will cause deterioration of pork quality due to uneven temperature distribution. In order to improve the temperature distribution in frozen pork during refrigeration storage, a simulation model for refrigeration of frozen pork was developed to investigate the differences in the temperature distribution in frozen pork piled up in different ways and consequently to find the best way of piling frozen pork up for long-term refrigeration. The results showed that samples piled up close to the walls had good temperature distribution. Concentrated piling was unfavorable for the samples on the bottom of trays. The area beneath the air outlet provided poor temperature distribution. In a refrigeration house, frozen pork should be kept far away from the walls as much as possible and scattered piling is recommended. In addition, frozen pork should not be piled up beneath the bottom of the air outlet.
