As shown in fig. 1, a temperature control method 10 is applicable to a direct-cooling type refrigeration apparatus including a compartment including a first zone and a second zone, and includes:
judging whether a trigger switch in the direct-cooling type refrigerating device is turned on or not:
if the trigger switch is turned on, executing a single-temperature-zone temperature control mode;
if the trigger switch is turned off, executing a multi-temperature-zone temperature control mode;
wherein, single warm area temperature control mode includes:
detecting a first operating temperature of the first region and a second operating temperature of the second region;
calculating a first difference between the first operating temperature and the second operating temperature;
judging whether the first difference value is smaller than a first preset difference value or not;
and if the first difference is larger than a first preset difference, controlling the first evaporator and/or the second evaporator of the direct-cooling type refrigerating device to refrigerate towards the corresponding first area and second area respectively.
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 for distinguishing a first area from a second area in the compartment; wherein, the trigger switch on the baffle is triggered to be opened.
The trigger switch is, for example, a photoelectric sensor, the photoelectric sensor is, for example, a side edge of the partition board, after the partition board is removed, the receiver in the compartment does not receive light emitted by the photoelectric sensor any more, and then the receiver feeds back a trigger signal to a main control board in the direct-cooling type refrigeration device, and the main control board controls the temperature control method to enter a single-temperature-zone temperature control mode according to the trigger signal, so as to adjust the temperature of the first evaporator and/or the second evaporator to jointly control the temperature in the first zone and the second zone, so that the temperatures of the first zone and the second zone are consistent with each other.
In addition, when the receiver in the compartment can receive the light emitted by the photoelectric sensor, and the receiver feeds back an un-triggered signal to the main control board in the direct-cooling type refrigerating device, the main control board controls the temperature control method to enter a multi-temperature-zone temperature control mode according to the un-triggered signal, so as to respectively regulate 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 compartment is divided into the first area and the second area by the single partition plate, and thus the multi-temperature-zone temperature control mode substantially corresponds to the 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 such that the temperatures of the three or more regions are controlled to be consistent with each other.
In a preferred embodiment, the multi-temperature zone temperature control mode includes:
detecting a first operating temperature of the first region and a second operating temperature of the second region;
calculating a second difference value between the first working temperature and the first preset temperature, comparing the second difference value with a second preset difference value, and controlling the first evaporator to refrigerate towards the first area when the second difference value is greater than the second preset difference value;
and calculating a third difference value between the second working temperature and the second preset temperature, comparing the third difference value with the third preset difference value, and controlling the second evaporator to refrigerate towards the first area when the third difference value is greater than the third preset difference value.
In this embodiment, in the multi-temperature-zone temperature control mode, the first evaporator and the second evaporator are individually controlled to refrigerate toward the corresponding first zone and the corresponding second zone, respectively. The refrigerant is controlled to flow towards the first evaporator or the second evaporator through the valve, 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 refrigeration device is a multi-temperature-zone temperature control mode.
Specifically, when the first working temperature does not reach the first preset temperature, and the first difference is greater than the first preset difference, the first working temperature of the first area is higher, and the refrigerant is controlled to flow towards the first evaporator through the first valve and refrigerate to the first area; and when the second working temperature does not reach the second preset temperature and the second difference is greater than the second preset difference, the second working temperature of the second area is higher, and the refrigerant is controlled to flow towards the second evaporator through the second valve and refrigerate to the second area.
Wherein, the first valve is communicated with the first evaporator; the second valve is communicated with the second evaporator. Preferably, the first valve and the second valve are solenoid valves, for example.
Wherein the first predetermined difference and the second predetermined difference are, for example, 2 ℃.
In addition, when the first difference is smaller than or equal to a first preset difference, the first valve is closed, and the first evaporator does not refrigerate; similarly, when the second difference is smaller than or equal to the second preset difference, the second valve is closed, and the second evaporator does not refrigerate.
In addition, in the single temperature zone temperature control mode, if the first difference is smaller than the first preset difference, the condition that the first evaporator of the direct cooling type refrigerating device is controlled to refrigerate towards the first area or the second evaporator of the direct cooling type refrigerating device is controlled to refrigerate towards the second area is similar to the multi-temperature zone temperature control mode, namely, the first preset temperature and the second preset temperature are respectively consistent with the set temperature of the system at the moment.
In a preferred embodiment, in the single-temperature zone temperature control mode, if the first difference is greater than the first preset difference, the step of controlling the first evaporator and/or the second evaporator of the direct-cooling type refrigeration device to refrigerate towards the corresponding first zone and the corresponding second zone respectively comprises:
comparing the first working temperature and the second working temperature with a system set temperature respectively;
if the first working temperature is consistent with the set temperature of the system and the second working temperature is higher than the set temperature of the system, controlling the second evaporator to refrigerate towards a second area;
and if the second working temperature is consistent with the set temperature of the system and the first working temperature is greater than the set temperature of the system, controlling the first evaporator to refrigerate towards the first area.
In this embodiment, after the main control board detects the trigger signal, the single-temperature-zone temperature control mode is entered, and in this control mode, the space in the room as a whole needs to control the temperature of the first zone to be consistent with the temperature of the second zone, that is, the temperature difference between the two zones should not be too large.
And the first evaporator and the second evaporator are controlled to work by judging whether one of the first working temperature and the second working temperature reaches the set temperature of the system, so that the aim of saving energy while regulating and controlling the temperature is fulfilled.
Further, if the first operating temperature is consistent with the system set temperature and the second operating temperature is greater than the system set temperature, the step of controlling the second evaporator to refrigerate towards the second area comprises:
comparing the first difference value with a system temperature difference set value;
if the first difference value is less than or equal to the set value of the system temperature difference, controlling the second evaporator to refrigerate towards a second area, or controlling the second evaporator to stop refrigerating;
and if the first difference value is larger than the set value of the system temperature difference, controlling the second evaporator to refrigerate towards the second area, and controlling the first evaporator to refrigerate towards the first area.
In this embodiment, by determining a magnitude relationship between a first difference between the first operating temperature and the second operating temperature and a system temperature difference set value, where when the first difference is greater than the system temperature difference set value, it indicates that a large temperature difference exists between the first area and the second area, at this time, even if the first operating temperature has reached the system set temperature, in order to reduce the first difference, the temperature of the first area and the temperature of the second area reach the system set temperature as soon as possible, and therefore, the second valve is opened, the second evaporator cools the second area, and the first valve is maintained open, and the first area is kept cooled, so that the first area and the second area can reach the system set temperature together in a short time.
In addition, when the first difference value is smaller than or equal to the set system temperature difference value, the temperature difference between the first area and the second area is small, the first working temperature reaches the set system temperature, at the moment, the second valve is opened, and the second evaporator refrigerates the second area. Of course, if the first difference is small enough, it indicates that the second operating temperature is substantially close to the system set temperature, and at this time, the second valve may be closed and the second evaporator may stop cooling.
Further, if the second operating temperature is consistent with the system set temperature and the first operating temperature is greater than the system set temperature, the step of controlling the first evaporator to refrigerate towards the first area comprises:
comparing the first difference value with a system temperature difference set value;
if the first difference value is less than or equal to the set value of the system temperature difference, controlling the first evaporator to refrigerate towards the first area, or controlling the first evaporator to stop refrigerating;
and if the first difference value is larger than the set value of the system temperature difference, controlling the first evaporator to refrigerate towards the first area, and controlling the second evaporator to refrigerate towards the second area.
In this embodiment, by determining a magnitude relationship between a first difference between the first operating temperature and the second operating temperature and a system temperature difference set value, where when the first difference is greater than the system temperature difference set value, it indicates that a large temperature difference exists between the first area and the second area, at this time, even if the second operating temperature has reached the system set temperature, in order to reduce the first difference, the temperature of the first area and the temperature of the second area reach the system set temperature as soon as possible, and therefore, the first valve is opened to cool the first area while the second valve is maintained open, and the second evaporator cools the second area, it is possible to achieve that the first area and the second area reach the system set temperature together in a short time.
In addition, when the first difference value is smaller than or equal to the set system temperature difference value, the temperature difference between the first area and the second area is small, the second working temperature reaches the set system temperature, at the moment, the first valve is opened, and the first evaporator refrigerates the first area. Of course, if the first difference is small enough, it indicates that the first operating temperature is substantially close to the system set temperature, and at this time, the first valve may be closed and the first evaporator may stop cooling.
In a preferred embodiment, the first predetermined difference value is different from the set value of the system temperature difference. Preferably, the value of the first preset difference is greater than the set value of the system temperature difference.

if the first working temperature is consistent with the set temperature of the system and the second working temperature is greater than the set temperature of the system, the step of controlling the second evaporator to refrigerate towards the second area comprises the following steps:

and if the fourth difference is larger than the fourth preset difference, controlling the second evaporator to refrigerate towards the second area, and controlling the first evaporator to refrigerate towards the first area.
When the difference between the fourth difference and the fourth preset difference is larger, in order to avoid the high temperature of the second area from influencing the first area, the first evaporator and the second evaporator are controlled to simultaneously maintain refrigeration until the fourth difference falls into the range of the fourth preset difference, and the first evaporator stops refrigeration; and stopping the refrigeration of the second evaporator when the fourth difference value is zero.
If the second working temperature is consistent with the set temperature of the system and the first working temperature is greater than the set temperature of the system, the step of controlling the first evaporator to refrigerate towards the first area comprises the following steps:
calculating a fifth difference between the first operating temperature and the system set temperature;
comparing the fifth difference value with a fifth preset difference value;

and if the fifth difference is greater than a fifth preset difference, controlling the first evaporator to refrigerate towards the first area, and controlling the second evaporator to refrigerate towards the second area.
