ABSTRACT
With the rapid development of our country's highway, the interior transportation expand gradually, the road refrigeration truck transportation demonstrates its fast developing tendency by degrees. Because the enhancement of collecting transport and the consciousness of environmental protection, the cargo transport not only require rapidness and safe, but also the freshness in quality .According to the incomplete statistical survey , the general capacity of refrigerating storage industry has break through 7 million tons per time until the end of the year of 2003.In our country,the companys refer to food refrigerate have exceed 20 thousand .The persons undertake this industry have exceed 800 thousands. The oueput of freeze food estimate have nearly 450 thousands tons per year.The output of refrigerate drink will break though 1.5 million tons. The technology of food refrigerate transportation is transport the food,especially some putrescibility food from a place to another place rapidly and successfully. The technology of food refrigerate transportation improve the food product , transport , sell, the health , living standard increasing food product classics beneficial result , improvement and improving the people have importance. At present, produce the refrigerator truck operating socially mostly existence a variety of prollem such as the refrigeration efficacy is shortage, energy consumption is big and so on. The problem use vacuum insulation board to be lagging material , designs the refrigerator car having the high heat insulation function. The main content designing that has: Refrigeration driving force and vehicle driving force must be unified; Design the independent driving force cut-out device; The engine and the compression engine link way;The connection way of refrigerator and the chassis; Compression engine refrigeration capacities choice and selections type; The choice of engine .
Key words: Compressor；Refrigerator；Refrigeration unit；Heat preservation compartment
