Full Description

This paper describes a modification of the model in the ASHRAE Handbook to predict the rate of air infiltration through doors into refrigerated facilities. The model sums the contributions of air tightness (infiltration when the door is closed), air infiltration due to door openings, and the additional air exchange caused by forklift traffic through the doors. The modified model was developed based on measured air infiltration rates through rapid-roll and sliding doors (with and without strip-curtain protection) into seven refrigerated warehouses with sizes ranging from 740 to 12,000 m3 (26,000 to 424,000 ft3) operating at temperatures ranging from 3 to –22 C (38 to –7 F) for a range of forklift movement rates.
