Because of the requirement of containerized shipment and the conscious of environmental protection, the cargo transport not only requires rapidness and safety, but also the quality of the goods must be retained freshness. So the production and application of refrigerator trucks have higher requirements. This design depends on CA1103P9K2LE chassis from FAW with the 10,000kg total mass, -5 the lowest degree and 4 hours maximum endurance. This design includes refrigerated equipments, insulation carriage and sub-frame. This design uses the independent type of cooling-plate for refrigeration with the help of the ground refrigeration unit to reduce the weight with full equipments. Using choose subdivision type as insulated body and using platform floor as sub-frame doesnt only make process sample but also save the cost. And it also can satisfy short distances transportations requirement of economy and usefulness.
