[0047] In the disclosed embodiment, since one side of the door body 50 faces the storage space, the temperature on this side is relatively low. The other side of the door body 50 faces the outside world, and the temperature on this side is relatively high. The door seal 502 of the door body 50 is located at the junction of the outside world and the storage space, and the temperature changes greatly.

The temperature sensor 30 is arranged on the side of the door seal 502 away from the door body. Since the door seal 502 is closely connected to the door body, the temperature sensor 30 is arranged on the side of the door seal 502 away from the door body, which is convenient for the installation of the temperature sensor 30.

[0058] Optionally, the door seal 502 may be provided with one heating device 20, or may be provided with multiple heating devices 20. Since the door seal 502 is relatively long, the door seal 502 may be provided with multiple heating devices 20 arranged in parallel, and a temperature sensor 30 is provided at a corresponding position where each heating device 20 is arranged, so that the opening of the heating devices 20 in multiple areas of the door seal 502 can be accurately controlled, further realizing accurate condensation prevention.

The controller 601 is electrically connected to the first heating device, the second heating device 201, the third heating device 202, the first temperature sensor 30, the second temperature sensor 301 and the third temperature sensor 302, so that the controller 601 can accurately control the operation of the corresponding heating device 20 according to the temperature of each position of the door body 50, and realize accurate control of the temperature changes of the three condensation-prone locations of the door body 50, thereby solving the condensation problem of the door lining, the door shell 501 and the door seal 502.

[0061] In the disclosed embodiment, the dew point thermometer 40 is arranged on the outside of the refrigeration equipment 10. The dew point thermometer 40 can obtain the humidity of the environment in which the door body 50 is located, and detect the critical temperature of condensation in the environment in which the door body 50 is located based on the humidity. The controller 601 receives the critical temperature of condensation, and then controls the operation of the heating device 20 based on the temperature detected by the temperature sensor 30 in the anti-condensation area. In this way, not only the temperature and humidity of the refrigeration equipment 10 itself can be considered, but also the temperature and humidity of the environment can be combined to improve the accuracy of the control of each heating device 20, thereby improving the accuracy of anti-condensation at various parts of the door body 50.

[0065] In the disclosed embodiment, when the door body 50 is opened and closed, the environment of different anti-condensation areas of the door body 50 changes. Therefore, the controller 601 first obtains the open / closed state of the door body 50, and then obtains the temperature of different anti-condensation areas of the door body 50 according to the open / closed state of the door body 50, and then judges the condensation risk of different anti-condensation areas of the door body 50, and controls the operation of the corresponding heating device 20.

When the first temperature is less than the critical temperature of condensation, it means that the door lining has reached the dew point, and the controller 601 controls the first heating device to work to increase the temperature of the door lining to avoid condensation of the door lining. When the first temperature is greater than or equal to the critical temperature of condensation, it means that there is no risk of condensation on the door lining, and the controller 601 controls the first heating device to stop working and wait for the door body 50 to close.

[0067] Optionally, when the detection device detects that the door body 50 is closed, the controller 601 controls the first heating device to stop working to prevent the heat of the first heating device from being transferred to the inside of the box body 60 .

When the third temperature is greater than or equal to the critical temperature of condensation, it means that the temperature of the door seal 502 is high and there is no risk of condensation, and the controller 601 controls the third heating device 202 to work.

[0069] Optionally, when the detection device detects that the door body 50 is closed and the third heating device 202 stops working, the controller 601 obtains the second temperature detected by the second temperature detection device of the door shell 501 and the critical temperature of condensation detected by the dew point thermometer 40. When the second temperature is less than the critical temperature of condensation, it means that the temperature of the door shell 501 has reached the dew point, and the second heating device 201 of the door shell 501 is controlled to work to avoid condensation of the door shell 501. When the second temperature is greater than or equal to the critical temperature of condensation, it means that the temperature of the door shell 501 is high and there is no risk of condensation in the door shell 501, and the second heating device 201 is controlled to stop working.
