Problems solved by technology

The present invention is mainly used to solve the problem that most of the current vacuum refrigerated vehicles have a low convective heat transfer capacity due to the thin air in the compartment, which leads to slow cooling speed in the compartment, cannot meet the requirement of continuous low temperature, and affects the storage of items in the compartment.

Abstract

The invention belongs to the technical field of agricultural product transportation, and particularly relates to an agricultural product refrigerated transport carriage based on a vacuum technology, wherein the carriage comprises a refrigeration component, a vacuum pump and a circulation component. Air in a carriage body is pumped outwards through the vacuum pump, so that the concentration of air around agricultural products is reduced, a refrigerating unit works, the temperature of a circulating pipeline is reduced, and the temperature of the air around the circulating pipeline is reduced; meanwhile, air flowing is promoted under the action of the circulating component, the temperature of the air in the carriage body is reduced, then the temperature of the agricultural products is reduced, vacuum refrigeration of the agricultural products is achieved, the agricultural products are kept fresh in the long-time transportation process, and the quality of the agricultural products is improved; and by arrangement of the circulating component, air flowing is increased, the heat convection speed of the air is increased, the vacuum cooling speed is increased, meanwhile, continuous low temperature is kept in the carriage body, the storage effect of the agricultural products is improved, and the quality of the agricultural products is improved.

Description

technical field [0001] The invention belongs to the technical field of agricultural product transportation, in particular to a refrigerated transportation carriage for agricultural products based on vacuum technology. Background technique [0002] A refrigerated truck refers to a closed van transport vehicle used to maintain the temperature of frozen or fresh goods. A refrigerated vehicle is a special refrigerated transport vehicle equipped with a refrigeration unit refrigeration unit and a polyurethane insulated compartment. Refrigerated vehicles are often used to transport frozen food, For dairy products, vegetables, fruits, vaccines and medicines, the vacuum refrigerated truck uses a vacuum pump to extract the air from the interior of the compartment, thereby increasing the vacuum degree in the compartment and reducing the air content in the compartment. The vacuum refrigerated vehicle has the following advantages: no pollution, can kill Dead insects, can reduce the produ...
