The car refrigerator is a device that draws power from the car cigarette lighter and has the function of refrigeration, and it is divided into electronic refrigeration chip type and compressor type from the principle.
The advantage of electronic refrigeration chip type is small size and light weight, but because the electronic refrigeration chip can only form a temperature difference of 30 degrees, so when the ambient temperature exceeds 38 degrees Celsius, the temperature inside the box must be higher than 8 degrees Celsius, and from the unloading of the car to the hospital storehouse stage without battery power.
Compressor-type advantages of strong refrigeration capacity, the disadvantage is that the weight is too large, inconvenient to carry, once the vehicle failure nowhere to get power, the risk is great. Furthermore, long-distance transportation if you go logistics, there is no way to power the refrigerator during transportation.
The principle of the refrigerator is to ship before the cold storage plate (2 degrees of solidification of the ice rows) for freezing, packing the goods and cold storage plate with the packing, transportation by the cold storage plate to maintain the temperature inside the box at 2 ~ 8 degrees Celsius. This way of transportation does not rely on external power supply, is currently the most commonly used cold chain transportation box.
RenSuo refrigerator box is designed for the requirements of the General Administration of Pharmaceutical Supervision, and fully considered the details of the use of the process. For the same city transportation, we have launched two series of products with 18 hours of cold storage (ambient temperature of 35 degrees Celsius) and 48 hours of long-distance transportation (ambient temperature of 35 degrees Celsius).
