Secondly, the unreasonable nature of current freezer structure leads to the function to be reasonable inadequately and perfect, for example many fruit vegetables freezer of meat freezer are few etc. and both have very big difference in the requirement to the temperature. Taking the cold chain logistics of double sinks as an example, although a certain number of cold storages and cold storage transportation fleets exist, the service function is single, and only single transportation of specific objects can be met. Most cold chain transportation single equipment on the market today has difficulty meeting a wide range of goods transportation because different goods have their own optimal storage temperatures, which requires that the range of temperature regulation be both large and precise. In addition, the requirement of temperature stability of individual products in the transportation process is relatively high, for example, in the current vaccine transportation, the temperature is required to be kept at 2-8 ℃ in the vaccine transportation, if the temperature exceeds or is lower than the specified temperature, the vaccine can be inactivated to different degrees, and therefore the characteristic requirement of the vaccine is that the stable and continuous low-temperature maintenance is required in the long-distance transportation.
