Based on the validation data, it can be concluded that:

1. Ultimate high temperature: The test results show that the 2 # Insulated Box (+ 5℃) can maintain the internal temperature of the box for 2~8℃ 72. hours under the environmental condition of extreme high temperature of 40℃. The temperature of P7 (upper top corner) is short relative to the insulation time, so it is suggested that the daily transportation monitoring point can be placed in this position;
2. Ultimate low temperature: The test results show that the 2 # Insulated Box (+ 5℃) can maintain the internal temperature of the box for 2~8℃ 100 hours under the extreme low temperature environmental condition of-25.7℃. The temperature of P7 (upper top corner) is short relative to the insulation time, so it is suggested that the daily transportation monitoring point can be placed in this position;

To sum up, the annual configuration of 2 # Insulated Box (2~8℃) can ensure that the items in the box are between 2~8℃ for at least 72 hours, and the temperature of P 7 (upper top corner) in the box is relatively short than the insulation time, it is suggested that the daily transportation monitoring point be placed in this position;

4.   matters need attention:

1. Select the right Insulated Box: select the appropriate size and material of the Insulated Box according to the type of items and the insulation time. For example, an Insulated Box used for food is usually different from the Insulated Box used for medical supplies.

2. Preheat or pre-cooling: Before using the Insulated Box, it can be preheated or pre-cooled as needed. For example, when storing hot food, use hot water in the Insulated Box for a few minutes; when storing cold food or cold drinks, it can be put into ice bags in advance or pre-cooled in the Insulated Box.

3. Correct loading: make sure that the items in the Insulated Box are not overcrowded and not too empty. Proper filling can help maintain the temperature and avoid excessive airflow due to temperature changes.

4. Seal check: ensure that the lid or door of the Insulated Box is well sealed to prevent the leakage of hot air or cold air. Poor sealing will greatly reduce the thermal insulation effect.

5. Cleaning and maintenance: after use, the Insulated Box should be cleaned in time to avoid food residue or odor. Keep the inside and outside of the Insulated Box clean, which can prolong its service life and maintain the thermal insulation effect.

6. Avoid direct sun exposure: put the Insulated Box in a cool place to avoid direct exposure to the sun, especially in summer, the overheating environment will affect its insulation effect.

7. Pay attention to safety: If the Insulated Box is used to transport sensitive items such as electronic equipment or chemicals, ensure that the relevant safety regulations are observed to avoid safety problems caused by temperature changes.
