The Insulation Effect Of The Cooler Bag

Put the ice pack into the -20 °C freezer to freeze for 24 hours to fully store cold, according to the standard configuration, the temperature in the refrigerated bag can be kept below 8 °C can reach more than 80 hours, suitable for a variety of medium and long-distance low-temperature drug transportation.

Other types of refrigerated bags:
The above describes the refrigerated bag based on material science, its refrigeration measures and related working conditions. It is a non-energy-consuming refrigeration tool. In addition, in the case of more stringent refrigeration requirements, it is necessary to use electronic refrigeration packages that require energy consumption to achieve the purpose of accurate refrigeration.
According to different needs, it is divided into high temperature refrigerated type, room temperature refrigerated type and low-text refrigerated type refrigerated bag.

For example, some drugs in clinical medicine need to be stored in a sub-zero temperature environment for a long time, and it is not possible to use a non-energy-consuming refrigerated bag, and a refrigerated bag with temperature control ability must be used.
This type of refrigerated bag has the ability of temperature collection, heating, cooling and so on. Closed-loop control for precise temperature control. The basic framework is: temperature acquisition - temperature comparison (comparison with the set temperature) - control method selection (heating or cooling) - temperature acquisition. In this way, a ring is formed to achieve the purpose of precise control. In addition, PID algorithms are commonly used in the field of automatic control to achieve accurate and fast control of control targets. Fuzzy algorithms are also used in control.
