Car refrigerator is a device with refrigeration function, which takes electricity from car cigarette lighter. In principle, it can be divided into electronic refrigeration plate type and compression type.
The advantages of electronic refrigerator are small size and light weight. However, because the electronic refrigerator can only form a temperature difference of 30 degrees, when the ambient temperature exceeds 38 degrees Celsius, the temperature inside the refrigerator must be higher than 8 degrees Celsius, and there is no battery power supply from unloading to hospital warehouse.
The advantage of compressor model is strong refrigeration capacity, but the disadvantage is that it is too heavy and inconvenient to carry. Once the vehicle breaks down, there is no place to get electricity, which is very risky. Furthermore, if long-distance transportation takes logistics, there is no way for the refrigerator to supply power during transportation.
The principle of refrigerator is to freeze the cold storage plate (ice row solidified at 2 degrees) before delivery, pack the goods together with the cold storage plate when packaging, and keep the temperature in the box at 2~8 degrees Celsius by the cold storage plate during transportation. This transportation mode does not depend on external power supply, and it is the most commonly used cold chain transportation box at present.
Renshuo refrigerator is designed according to the requirements of the General Administration of Drug Administration, and all kinds of details in the use process are fully considered. Two series of products were introduced: transportation in the same city and refrigeration 18 hours (ambient temperature 35 degrees Celsius) and long-distance transportation for 48 hours (ambient temperature 35 degrees Celsius).
