to pass across the
fruit as the truck moves. However, the winter temperature is similar
to the temperature of refrigerated trucks and indicates ventilation
with ambient air would not be required. Use of non-refrigerated
trucks would be a 20–25% cost saving to the industry (D. Spennigal, Harker Transport, pers. comm.) and would significantly reduce
energy, refrigerants and greenhouse gas emissions in the supply
chain.
