And S23, determining the cold releasing amount in unit time according to the total latent heat, the cold releasing time and the average temperature difference between the inside and the outside of the cold storage box.

The average temperature difference between the inside and the outside of the cold storage box is the average temperature difference measured in the experiment. The amount of cold released per unit time can be calculated by formula one.

The formula I is as follows: cold release quantity per unit time (total latent heat quantity/long time of cold release/average temperature difference inside and outside cold storage box)

To improve accuracy, the average value can be found through multiple experiments.

One or more thermometers may be provided. When a plurality of thermometers are provided, the internal temperature or the external temperature of the cold storage tank is an average value of the plurality of thermometers. The position where the thermometer is disposed is not limited.

And S32, acquiring the temperature difference between the inside and the outside of the cold storage box at the current moment.

And S33, determining a temperature difference coefficient according to the average temperature difference value and the current time temperature difference value.

Specifically, the temperature difference coefficient can be obtained by calculating the formula two.

The formula II is as follows: temperature difference coefficient is equal to the current time temperature difference/average temperature difference

And S4, determining the released cold quantity corresponding to the cold storage box at the current time according to the unit time cold release quantity, the initial time, the current time and the temperature difference coefficient.

Specifically, the released cold quantity corresponding to the current moment can be obtained through calculation based on the formula III.

According to the method for determining the released cold amount, the cold amount released in the cold storage box in unit time is obtained, the initial time and the current time of cold charging of the cold storage box are obtained, the temperature difference coefficient of the cold storage box is obtained, and the released cold amount corresponding to the cold storage box at the current time is determined according to the cold amount released in unit time, the initial time, the current time and the temperature difference coefficient, so that the quantity of cold released in the cold storage box can be accurately calculated, the cold amount of the cold storage box is accurately quantized, the cold amount of the cold storage box is intelligently managed, and the heat preservation effect of goods is guaranteed.
