Abstract: The objective of this research was to determine the effect of pallet loading and bracing patterns on air distribution inside refrigerated semi-trailers transporting fresh horticultural produce. The performance of air circulation systems was investigated in 20 trailers with mixed loads arranged in either centerline, offset or pinwheel patterns. In some tests, vinyl air bags were placed horizontally or vertically to brace every pair or every other pair of produce pallets. Pearson product-moment correlation coefficients were calculated based on temperature data, and were used as indices to represent the relative air distribution at different locations within semi-trailers. Pearson correlation coefficients and coefficients of determination were used to quantify the effects of pallet loading and bracing patterns on relative air distribution. Results obtained for the 20 field tests varied greatly within each category of loading and bracing patterns. Although no firm conclusions could be drawn, it was observed that arranging pallets in a pinwheel pattern tended to assist air circulation better than the offset pattern. Using air bags horizontally or not using air bags at all tended to promote better air circulation than using air bags vertically for bracing pallets inside refrigeration semi-trailers.
