The freezer cooling temperature environment inside. The compressor refrigeration module 11 can directly adopt a conventional compressor refrigeration method, and the compressor refrigeration module 11 is composed of, for example, at least a compressor, a condenser, a refrigerant flow controller, and an evaporation gas. The compressor can directly adopt a conventional variable frequency compressor or a conventional non-inverting compressor, and the condenser, the refrigerant flow controller, the vaporizer, and the like can also directly adopt corresponding conventional components. The refrigeration capacity of the compressor refrigeration module 11 is to comply with the temperature transport conditions of the article on the refrigeration chain. The power source of the compressor refrigeration module 11 can be used by using a battery (not shown) provided in the mobile refrigeration equipment 1 or using external power (for example, utility power or vehicle power, etc.).

The inner tank 13 can adopt a tank structure, and the inner tank 13 has a chamber 131 and a cold source energy storage device 133. A chamber 131 is used to place the item. The cold source energy storage device 133 is configured to store a cold source, and the function of the cold source is to reduce the temperature rise change of the chamber 131 within a predetermined time, thereby when the compressor refrigeration module 11 is not operating, The temperature of the chamber 131 can be maintained as much as possible.

The cold source energy storage device 133 is disposed, for example, around the inner side wall of the inner tank 13, for example, on the inner side wall at the center of the inner tank 13. The cold source energy storage device 133, for example, employs a semi-closed cavity structure having an injection port (not shown) and an escape port (not shown). The injection port is for injecting an aqueous solution containing a salt substance, and the escape port is for allowing an aqueous solution located inside the cavity to flow out. The aqueous solution is first injected into the cavity before the article is placed in the chamber 131, and the compressor refrigeration module 11 freezes the aqueous solution in the cavity into ice cubes, and the ice cubes are A specific example of a cold source. The cold source of the cold source energy storage device 133 of the present invention preferably has a cold retention capability, which can be supplied to a predetermined time, for example, within 4 hours, that is, the chamber 131 is solely dependent on the cold source energy storage device 133. The cold source is capable of maintaining the article within a predetermined temperature range within the predetermined time.

As shown in step 205. When the cold source of the cold source energy storage device 133 loses the cooling effect, the mobile refrigeration cooling device 1 immediately starts the compressor refrigeration module 11.

Referring to Figure 5, in accordance with the spirit of Figure 4, the mobile refrigeration equipment 1 performs steps 501-507. The mobile chiller 1 is further provided with at least a temperature sensing and transmitting module and a processor. The function of the temperature sensing and transfer module is to sense the current temperature of the chamber 131 and to transmit a temperature signal corresponding to the current temperature to the processor. The specific example of the temperature sensing and transmission module can directly adopt the conventional temperature sensing related circuit means and the conventional signal transmission means. The temperature sensing and transmitting module includes, for example, at least one temperature sensor and one temperature signal transmission line.

The processor automatically measures the current temperature of the chamber 131 every predetermined time interval (for example, 5 minutes) and receives the temperature signal via the temperature signal transmission line.

In step 501, the processor determines whether the destination of the item shipment has arrived. If it has not arrived, the process proceeds to step 503, and if the destination has been reached, the execution ends. Furthermore, the mobile cryocooling device 1 of the present invention can further be coupled to a conventional GPS receiving device that can provide the current geographic location of the vehicle carrying the item for use by the processor to determine whether it has arrived. The destination of the item to be shipped.

In step 503, the processor monitors the cooling effect of the cold source energy storage device 133. In step 505, the processor determines that when the cold source of the cold source energy storage device 133 loses the cold preservation effect, the process proceeds to step 507, otherwise, returns to step 501.
