Abstract：Medical cold boxes are essential thermal insulation equipment in the process of storage and transportation of drugs, vaccines and blood. The temperature parameter plays an important role in drug quality and vaccine activity. Combined with the existing technical specifications, this paper puts forward the corresponding calibration methods for three key indicators: temperature distribution characteristics of the boxes, indication error of the temperature automatic monitoring system, and influence of the unpacking operation on the temperature distribution and change in the refrigerator. Combined with the actual situation, this paper gives a relatively reasonable expression method of the temperature calibration results of medical cold boxes, and it is helpful for the calibration of the cold equipment , cold chain transportation equipment and strain storage equipment.
