Description

Electric-driven refrigerating, cold-storage, energy saving and environment friendly freezing, cold storage truck
Technical field
A kind of electric-driven refrigerating, cold-storage, energy saving and environment friendly freezing, cold storage truck, a kind of applicable perishable items is freezing, cold preservation The novel energy-conserving of transport, environmental protection freezing, cold storage truck.
Background technology
Day by day reduce at world energy sources, environmental pollution increasingly severe in the case of, each state all make great efforts development, utilize can The clean energy resource of regeneration, the especially development and application technology to energy accumulating technique.At present, food product refrigeration, cold-storage transporting automobile are Most important part in food refrigerated conveyer chain, subzero 5 DEG C to+5 DEG C of temperature requirement in refrigerator carriage, in refrigerator truck compartment Temperature can reach subzero about 18 DEG C.Freezing, cold storage truck is required for driving fine frozen unit refrigeration, for providing cold in compartment Source.General refrigeration machine component stand alone type and dependent formula two kinds, the power of stand alone type fine frozen unit from automobile primary electromotor, Dependent formula fine frozen unit is driven by independent electromotor.The most that drive form, drive power be all gasoline engine or Diesel engine, will consume gasoline or diesel oil.The fuel consumption utilizing gasoline engine, Diesel Driven to freeze is big, and cost of transportation is the highest again Pollute environment.
People have been working hard explore, and seek refrigerating method and the energy conserving system of a kind of low cost, and Some vehicles have employed Gasoline engine adds motor twin-engined drives form, and solving stops has a rest and refrigeration problem during stagnation of movement.Owing to there is no cold-storage measure And equipment, during running car, it is still desirable to gasoline engine or Diesel Driven refrigeration unit refrigeration.The electric drive system that we release Cold, cold-storage, energy saving and environment friendly freezing, cold storage truck, major impetus is in night of automobile stagnation of movement and daytime, the supper rest period Valley period power power, the electric power of this period is because consumption is little, and the overwhelming majority is wasted.Refrigeration unit make use of this The electric refrigeration of individual period, cold-storage, decrease the waste of valley period power power, and electricity price is low, reduces cost of transportation.The driven by power system of utilization Cold, Energy Efficiency Ratio is high, simple, convenient, has the place of power supply to freeze, supplements cold.Need not oil, cleaning, clean, there is no secondary Pollute.
Before it is proposed that utilize the new ideas of valley period power power refrigeration, cold-storage, home and abroad is freezing, the sending out of cold storage truck Exhibition trend, remains on the basis of existing, and the direction that, automaticity big to capacity is high is developed;To temperature automatically controlled with record, " syllogic " refrigerating transport vehicle of satellite monitoring and the goods direction that can simultaneously transport three kinds of different temperatures requirements are developed.Utilize paddy Phase electric refrigeration, the freezing of cold-storage, cold storage truck represent the new development trend of freezing, cold storage truck and direction.
Summary of the invention
A kind of electric-driven refrigerating, cold-storage, energy saving and environment friendly freezing, cold storage truck, a kind of applicable perishable items is freezing, cold preservation The novel energy-conserving of transport, environmental protection freezing, cold storage truck.
Offer a kind of seriation electric-driven refrigerating, cold-storage, energy saving and environment friendly freezing, cold preservation are provided Automobile, refrigeration compressor set is driven by power, has salt eutectic phase-change cold-storage device in refrigeration system.This electric-driven refrigerating, storage The required in motion cold of freezing cold, energy saving and environment friendly, cold storage truck is provided by salt eutectic phase-change cold-storage device.
In order to achieve the above object, the technical solution adopted in the present invention is:
