Temperature Managing Method For Cooling Transportation Of Cargo Without Inner Thermal Source

China's cold storage chain is facing the severe global competition at the present time, and the cooling transportation is the bottleneck of the cold storage chain. As convenient operation and lower cost, the cooling transportation thus has more space to develop. Yet, in the cooling transportation, by using the phase-changed material to keep cool, there are problems such as obvious unevenness of temperature distribution, shorter cooling time, no perfect method of cargo quality assessment, etc. There are not much research documents and technical data for practical use in China and overseas. This thesis takes the whole cooling transportation without inner thermal source as the study subject, analyzes the affection to the cooling effect from all the factors in the cooling transportation. The purpose is to establish the optimizing temperature managing system in the cooling transportation. That would bring the theoretical meaning and practical value to China's cooling transportation.By considering the affection to the cargo temperature value and the temperature distribution from all the factors inside the cooling container, the thesis try to establish the relations between the cargo's average temperature and the unevenness of temperature, propose the assessment method that may comprehensively reflect the cargo's cooling effects, offer useful search for seting up the assessment system of the cooling transportation.Taking the assessment method of the cooling effect as the theoretical base, it had established the outer temperature prediction model of the geographical locations when cargo moving in every time units, and the average temperature prediction model of the cargo inside the phase-changing material container. It raised the prediction method of the optimizing usage amount of the phase-changed material in the cooling transportation. This method may avoid the waste and high cost of the phase-changed material in the cooling transportation, or insufficient using amount of phase-changed material that may cause the cargo rotten and not able to guarantee the cargo's quality in the limited temperature scope. The effects of the cooling transportation will be economically improved.Finally it conducted a temperature managing method in the cooling transportation, that included the using prediction of the phase-changed material before the transportation, the whole temperature monitoring and controlling in the transportation, the effective feedback of the temperature and preparing the data table after the end of the transportation, and put them into the practical use. This method improved the traditional managing method that only caring on the starting and finishing points, but not the whole transportation process. It has the significance for ensuring the cargo's quality, lowering the loss of the easy-rotten goods, saving energy and improving the service of the forwarders.The above works will have the obvious theoretical meaning and practical value for perfecting the cooling transportation system, improving the cargo's quality, lowering the energy consumption, and will benefit the sustainable development of China's cooling transportation industry.
