According to the report: according to the estimation of China Refrigeration society, due to the backward preservation technology, about 20-25% of fruits and 30% of vegetables are rotted and lost in transit transportation and storage in China every year. The total loss is up to billion tons every year, worth 75 billion yuan. This amazing waste shows that there is a huge development space for refrigerated transportation in China.

It was learned from the first "Shanghai Refrigeration Festival" held on August 18 that at present, China's annual output of poultry and meat products is 30 million tons, nearly 20 million tons of eggs, about 6 million tons of milk, dairy products, 61 million tons of fruits, and nearly 35000 tons of vegetables. With the improvement of living standards, these perishable foods need to be refrigerated and transported.

According to the prediction of the railway department, from 2001 to 2010, the annual transportation volume of perishable food in China will increase from 19 million tons to 75 million tons. At present, there are about 8000 railway refrigerated vehicles in China, about half of which are mechanical refrigerated vehicles, so it is necessary to vigorously develop new railway refrigerated vehicles. At present, a new type of railway refrigerator with environmental protection refrigerant has been used in Jiangwan thermal insulation depot of Shanghai Railway Bureau. The automatic control, operation display, fault prediction and safety alarm system of the new type of railway refrigerator have been improved day by day.

The convenient and flexible refrigerated vehicles play an increasingly important role in refrigerated transportation in China. It is predicted that from 2001 to 2005, the annual traffic volume of highway refrigerated transportation will increase from 12.58 million tons to 17.67 million tons, with an average annual growth of 7%. The traffic volume of highway refrigerated transportation will also increase from 25% to 30% of the total refrigerated cargo traffic. At the same time, the demand for refrigerated vehicles in China will also increase significantly. A large part of medium-sized vehicles will be replaced by light, micro and heavy vehicles. New energy refrigerated vehicles with new refrigeration methods such as liquid nitrogen, carbon dioxide and cold storage plate are more and more popular.
