Referring to fig. 1, an embodiment of an ice bank cold storage system 10 is used to store cold for an ice bank to freeze a phase change material in the ice bank. The frozen ice box is used for refrigerating target objects in cold chain transportation. The thermal insulation ice box cold accumulation system 10 comprises an insulation box 100, a refrigeration assembly 200, a controller 300 and a temperature sensing assembly 400. The insulation can 100 is provided with an accommodating cavity therein, the ice box is placed in the insulation can 100, and the refrigerating assembly 200 is used for refrigerating the insulation can 100 to reduce the temperature of the insulation can 100 so as to freeze the ice box. The controller 300 is connected to the cooling module 200 to control the cooling module 200. The temperature sensing assembly 400 includes a first temperature sensing element 410 and a mounting box 420, and the mounting box 420 is disposed in the heat insulation box 100 and is cooled by the cooling assembly 200 together with the ice box. The installation box 420 is internally provided with an accommodating cavity, the installation box 420 is also internally provided with a phase change material, and the phase change material in the installation box 420 is the same as the phase change material in the ice box. The first temperature sensing element 410 is disposed in the installation box 420 and configured to sense a temperature of the phase change material in the installation box 420, the controller 300 is set with a first preset value, until the first temperature sensing element 410 senses that the temperature of the phase change material in the installation box 420 is reduced to the first preset value, the first temperature sensing element 410 sends a first detection signal to the controller 300, and the controller 300 controls the refrigeration assembly 200 to stop refrigeration. It should be noted that the first preset value may be set to a specific phase-change temperature value, or may be set to a temperature range lower than the phase-change temperature, for example, 2 ℃ to 3 ℃ lower than the phase-change temperature, in order to avoid incomplete cooling of the ice box.
In the ice box cold storage system 10, since the phase change material in the installation box 420 is the same as the phase change material in the ice box, the ice box and the installation box 420 are cooled by the refrigeration component 200 at the same time, the temperature of the phase change material in the installation box 420 is monitored, when the temperature of the phase change material in the installation box 420 is monitored to reach a first preset value, that is, the temperature is lower than the phase change temperature, the refrigeration component 200 stops refrigerating, and then the ice box is taken out for use, so that the ice box can be accurately cooled, excessive cold storage cannot be caused, the efficiency is improved, and the energy is saved.
In one embodiment, the same material is used for the installation box 420 and the insulation box 100, so that the same storage environment can be provided for the phase change materials in the insulation box 100 and the installation box 420, and the influence of different materials on the heat transfer efficiency is reduced. The mounting box 420 and the heat preservation box 100 are both provided with openings on the top wall, and the openings are hinged with covers. In other embodiments, openings may be provided on the sidewalls of the installation box 420 and the insulation box 100, and a door body is hinged to the sidewalls, so as to open or close the installation box 420 and the insulation box 100.
In one embodiment, the first temperature sensing element 410 is a temperature sensor.
In one embodiment, since the temperature in the thermal container 100 (i.e., the ambient temperature) is 15 ℃ to 20 ℃ lower than the phase transition temperature of the phase change material, the ice box can be sufficiently cooled, further reduction of the ambient temperature will result in higher energy consumption, and continuous cooling is not necessary. Therefore, the ice bank cold storage system 10 is further provided with the second temperature sensing member 500. The second temperature sensing element 500 is disposed in the heat insulation box 100 and is used for sensing the temperature in the heat insulation box 100, the second temperature sensing element 500 can send a second detection signal to the controller 300, and the controller 300 controls the working state of the refrigeration assembly 200 according to the second detection signal.

When the second temperature sensing element 500 detects that the temperature in the heat insulation box 100 reaches the temperature range of the second preset value, the second temperature sensing element 500 sends a second detection signal to the controller 300, the controller 300 controls the refrigeration assembly 200 to be opened or closed, so that the temperature in the heat insulation box 100 is maintained to be 15-20 ℃ lower than the temperature of the phase change point of the phase change material in the ice box, the temperature of the phase change material in the ice box is continuously cooled after releasing heat at the temperature, and the temperature of the phase change material in the temperature sensing module is also synchronously cooled. Avoiding extra energy waste caused by too low temperature in the incubator 100. It should be noted that the second preset value can also be freely set according to the requirement. Specifically, the second temperature sensing element 500 is a temperature sensor.
Normally, the ice box is not used immediately after the cold accumulation is finished, but is continuously refrigerated until the ice box is taken out when needed. In order to store the ice box at constant temperature, that is, to control the ambient temperature below the phase transition temperature of the phase change material in the ice box, it should be noted that the ambient temperature is 2 to 3 ℃ lower than the phase transition temperature in order to save energy consumption and avoid excessive cooling. Thus, the refrigeration assembly 200 sets the constant temperature standby mode to be implemented. When the controller 300 detects the first detection signal of the first temperature sensing element 410, the controller 300 controls the cooling assembly 200 to switch to the constant temperature standby mode. Specifically, the controller 300 is further configured with a third preset value, and the range of the third preset value is set to be between 2 ℃ and 3 ℃ lower than the phase transition temperature, and may be any specific value or any value interval within the range. When the controller 300 detects the first detection signal of the first temperature sensing element 410, the controller 300 controls the second temperature sensing element 500 to sense the temperature in the incubator. When the ambient temperature is lower than the third preset value, the second temperature sensing element 500 feeds back the detected temperature result to the controller 300, and the controller 300 controls the refrigeration assembly 200 to work for refrigeration. When the ambient temperature is higher than the third preset value, the second temperature sensing element 500 feeds back the detected temperature result to the controller 300, and the controller 300 controls the refrigeration assembly 200 to stop working, so as to control the ambient temperature within the third preset value range. It should be noted that the temperature difference between the on and off states of the refrigeration assembly 200 can be set to ± 1 ℃, and meanwhile, the third preset value can be freely set according to the requirement.
In one embodiment, the controller 300 includes a single chip and a control circuit. The single chip microcomputer is preset with programs corresponding to the cold accumulation mode and the constant temperature standby mode, and the control circuit is used for controlling the refrigeration assembly 200 to be opened or closed.
