Recently

the development and application of the 3rd generation of new refrigerated resource

typically liquid carbon dioxide

has become an important study of developing refrigerated transportation. Comparison with the mechanical refrigerated lorry and the cooling board lorry

the liquid carbon dioxide refrigerated lorry has better predominance from the point of view of economy and environment. This paper mainly analyzes the economy of those three ways of refrigeration from initial investment

depreciation and maintenance costs of equipment

and the cost of energy consumption. The results show that the run fee of the mechanical refrigerated lorry and the run fee of the cooling board are 42% and 28% individually higher than that of the liquid carbon dioxide refrigerated lorry.
