An empirical model based on Tamm's equation was developed to predict the rate of air infiltration through doors into refrigerated buildings. The model sums the contributions of air-tightness, air infiltration due to door openings and the additional air exchange caused by forklift traffic through the doors. The model was validated against measured air infiltration rates through rapid-roll and sliding doors into 7 commercial coldstores with sizes ranging from 740 to 12,000 m 3 operating at temperatures ranging from 3.3 to –21.8 °C.
