Cold-storage container with very large volume

Abstract

A preserving container with very large volume is composed of power case and cold storage case. Said power case consists of industrial control computer, diesel engine as power source, oil tank, accumulator, heat radiator for diesel engine, transfer case, and refrigerating unit. Said refrigerating unit comprises compressor, liquid storage, main control valve for switching between heating and refrigerating, electric speed reducer of main control valve, evaporator, condenser, condensing fan and circulating pipeline.

Description

1. Technical field [0001] The invention relates to a precooling refrigerated container, which belongs to a material storage or transportation container. 2. Background technology [0002] With the rapid development of the world economy, the transportation industry is highly developed, which provides a huge business opportunity for food preservation and transportation. Therefore, fresh-keeping containers came into being. At present, typical representatives in this technical field are: [0003] 1. Modified atmosphere fresh-keeping refrigerated container, application number: 97200254; [0004] 2. Large-capacity refrigerated container, application number: 97122619; [0005] 3. Mechanical cold plate refrigerated container, application number: 96236720; [0006] 4. A new refrigerated and fresh-keeping container, application number: 92236008. [0007] Its major deficiency of above-mentioned four prior art is: one, there is no pre-cooling function. Practice has proved that for ...

AI Technical Summary

Problems solved by technology

[0007] Its main deficiency of above-mentioned four prior art is: one, there is no pre-cooling function

Not only does this add extra cost and lengthen turnaround time, but it also reduces the quality of food preservation by not being able to pre-cool "on the fly"

In addition, the non-precooling design of refrigerated containers inevitably leads to the requirement of multiple reshipments for transported goods

Only in terms of the nature of perishable food, whether it is fruit and vegetable preservation or meat preservation, repeated bad luck will be extremely unfavorable

2. Unable to enter multimodal transport

The refrigerated containers in the above-mentioned prior art 2-4 are all external power supply types. Due to the limitation of energy sources, it is impossible to enter multimodal transport in actual operation and realize the "door-to-door" function

3. The efficiency of energy conversion is low

The refrigerated container in the prior art 1 is powered by a diesel generator set, and only about 50% of the mechanical energy is transferred from the diesel engine to the compressor during the entire mechanical energy-electrical energy-mechanical energy conversion process, which also occupies very valuable vehicle or ship. load space, so the driving method of the above-mentioned prior art is not only uneconomical and reasonable in terms of energy utilization, but also very unfavorable to vehicle-mounted and ship-mounted containers

4. Improper ventilation

Makes most temperature-sensitive cargo impossible to haul

5. Unable to perform cooling and heating conversion

This reduces the scope of its use area and season, and greatly reduces its adaptability to the environment.

6. Does not have packaging and sterilization functions

None of the above-mentioned prior art 1-4 has these two functions
