Further, in the single temperature zone temperature control mode, if the first difference is greater than the system temperature difference set value, the step of controlling the first evaporator of the direct cooling type refrigeration device to refrigerate to the first zone and/or controlling the second evaporator of the direct cooling type refrigeration device to refrigerate to the second zone further comprises:

In a preferred embodiment, the step of determining whether the trigger switch in the direct cooling type refrigeration device is turned on includes:
removing a partition plate in the compartment for distinguishing the first region from the second region; wherein, trigger switch on the baffle is triggered and opened.
The trigger switch is a photoelectric sensor, for example, on the side of the partition board, after the partition board is removed, the indoor receiver does not receive light rays emitted by the photoelectric sensor, and then the receiver feeds back a trigger signal to a main control board in the direct-cooling refrigerating device, and the main control board controls to enter a single-temperature-area temperature control mode according to the trigger signal so as to adjust the first evaporator and/or the second evaporator to jointly control the temperature in the first area and the second area, so that the temperatures of the first area and the second area are consistent with each other.
In addition, when the indoor receiver can receive the light rays sent by the photoelectric sensor, the receiver feeds back an un-triggered signal to a main control board in the direct-cooling refrigerating device, and the main control board controls the temperature control method to enter a multi-temperature-area temperature control mode according to the un-triggered signal so as to respectively adjust the first evaporator or the second evaporator, so that the temperature of the first area reaches a first preset temperature, and the temperature of the second area reaches a second preset temperature.
In this embodiment, the first region and the second region are separated by a single partition, and thus the multi-temperature-zone temperature control mode corresponds to a dual-temperature-zone temperature control mode. However, in other embodiments of the present invention, a plurality of partitions are provided to divide the chamber into three or more regions, and in this case, the multi-temperature-zone temperature control mode may be to control the three or more regions so that the temperatures of the three or more regions are consistent with each other.

detecting a first operating temperature of the first region and a second operating temperature of the second region;
calculating a third difference value between the first working temperature and the first preset temperature, comparing the third difference value with the first preset difference value, and controlling the first evaporator to refrigerate towards the first area when the third difference value is larger than the first preset difference value;
and calculating a fourth difference value between the second working temperature and the second preset temperature, comparing the fourth difference value with the second preset difference value, and controlling the second evaporator to refrigerate towards the second area when the fourth difference value is larger than the second preset difference value.
In this embodiment, in the multi-temperature-zone temperature control mode, the first evaporator and the second evaporator individually control refrigeration toward the corresponding first zone and second zone, respectively. The valve controls the refrigerant to flow towards the first evaporator or the second evaporator, so that the first evaporator and the second evaporator respectively refrigerate towards the corresponding first area and the second area. The default temperature control mode of the direct cooling type refrigerating device is a multi-temperature-zone temperature control mode.
Specifically, when the first working temperature does not reach the first preset temperature, the first difference value is larger than the first preset difference value, which indicates that the first working temperature of the first area is higher, and the refrigerant is independently controlled to flow towards the first evaporator through the first valve to refrigerate the first area; and when the second working temperature does not reach the second preset temperature, the second difference value is larger than the second preset difference value, which indicates that the second working temperature of the second area is higher, and the refrigerant is independently controlled to flow towards the second evaporator through the second valve to refrigerate the second area.
Wherein the first valve is communicated with the first evaporator; the second valve is in communication with the second evaporator. Preferably, the first valve and the second valve are, for example, solenoid valves.
Wherein the first preset difference and the second preset difference are for example 2 ℃.
In addition, when the third difference value is smaller than or equal to the first preset difference value, the first valve is closed, and the first evaporator does not refrigerate; similarly, when the fourth difference is less than or equal to the second preset difference, the second valve is closed, and the second evaporator does not refrigerate.
