New energy multi-input refrigerating system of refrigerator car

Abstract

The invention discloses a new energy multi-input refrigerating system of a refrigerator car. The system comprises a compartment, and an assembly box and an integration box are assembled in the top face of an inner cavity and the upper end of the right side of the outer side wall of the compartment correspondingly. An evaporator is assembled in the assembly box, a vehicle-mounted two-way piston refrigeration compressor, an electric scroll compressor and a condenser are assembled in the integration box, and a lithium battery pack is fixedly assembled in the lower side of the compartment and electrically connected with the electric scroll compressor. Double power of the vehicle-mounted bidirectional piston refrigeration compressor and the electric scroll compressor is adopted for refrigeration, during long-time parking and unloading, refrigeration of the vehicle-mounted bidirectional piston refrigeration compressor is converted into refrigeration of the electric scroll compressor, the lithium battery pack supplies power, energy conservation and environmental protection are achieved, noise is low, and refrigeration of the refrigeration vehicle is not affected when an engine is damaged.

Description

technical field [0001] The invention relates to the technical field of transportation equipment, in particular to a refrigeration system for a refrigerated vehicle with multiple input of new energy. Background technique [0002] A refrigerated truck refers to a closed van transport vehicle used to transport frozen or fresh goods. A refrigerated vehicle is a special refrigerated transport vehicle equipped with a refrigeration unit of a refrigeration unit and a polyurethane insulated compartment. Refrigerated trucks are often used to transport dairy products, vegetables and fruits, vaccines and medicines, etc. When the traditional refrigerated truck is unloading, it cannot turn off the engine to ensure the normal operation of the refrigeration system. When unloading for a long time, it will consume a lot of fuel, not save energy, and will emit a lot of exhaust gas and generate a lot of noise. If the engine of the refrigerated truck fails, it will affect the refrigeration of th...

Problems solved by technology

When the traditional refrigerated truck is unloading, it cannot turn off the engine to ensure the normal operation of the refrigeration system. When unloading for a long time, it will consume a lot of fuel, not save energy, and will emit a lot of exhaust gas and generate a lot of noise. If the engine of the refrigerated truck fails, it will affect the refrigeration of the truck. work, for this purpose, we propose a new energy multi-input refrigerated vehicle refrigeration system
