The invention provides a temperature control method, which is suitable for direct-cooling refrigeration devices and realizes intelligent control of the temperatures in multiple areas of the direct-cooling refrigeration device. Especially when the direct-cooling refrigeration device enters a single temperature zone from a multi-temperature zone, it can realize The working temperature of the first zone is consistent with the working temperature of the second zone, which helps to reduce the temperature difference of the refrigeration device.

As shown in Figure 1, a temperature control method 10 is suitable for a direct cooling refrigeration device. The direct cooling refrigeration device includes a compartment, and the compartment includes a first area and a second area, which includes:

Determine whether the trigger switch in the direct cooling refrigeration device is turned on:

If the trigger switch is turned on, the single temperature zone temperature control mode will be executed;

If the trigger switch is closed, the multi-temperature zone temperature control mode will be executed;

Among them, the single temperature zone temperature control mode includes:

detecting the first operating temperature of the first area and the second operating temperature of the second area;

calculating a first difference between the first operating temperature and the second operating temperature;

Determine whether the first difference is less than the first preset difference;

If the first difference is greater than the first preset difference, the first evaporator and/or the second evaporator of the direct cooling refrigeration device are controlled to cool the corresponding first area and the second area respectively.

In a preferred embodiment, the step of determining whether the trigger switch in the direct cooling refrigeration device is turned on includes:

The partition in the compartment used to distinguish the first area and the second area is removed; wherein, the trigger switch on the partition is triggered to turn on.

Among them, the trigger switch is, for example, a photoelectric sensor. The photoelectric sensor is, for example, placed on the side of the partition. After the partition is removed, the receiver in the room no longer receives the light emitted by the photoelectric sensor, and then the receiver feeds back the trigger signal to the direct cooling The main control board in the refrigeration device controls the temperature control method to enter the single temperature zone temperature control mode according to the trigger signal to adjust the first evaporator and/or the second evaporator to jointly control the first area and the second area. so that the temperatures of the first region and the second region are consistent with each other.

In addition, when the indoor receiver can receive the light emitted by the photoelectric sensor, the receiver then feeds back the untriggered signal to the main control board in the direct cooling refrigeration device. The main control board controls the temperature control method to enter the multi-temperature mode based on the untriggered signal. The zone temperature control mode is used to adjust the first evaporator or the second evaporator respectively, so that the temperature of the first zone reaches the first preset temperature, and the temperature of the second zone reaches the second preset temperature.

It should be noted that in this embodiment, a single partition divides the chamber into a first area and a second area. Therefore, the multi-temperature zone temperature control mode essentially corresponds to the dual-temperature zone temperature control mode. However, in other embodiments of the present invention, multiple partitions are provided to separate the chamber into three or more areas. At this time, the multi-temperature zone temperature control mode may be to control three or more areas so that the three areas The temperatures of two or more regions are consistent with each other.

In a preferred embodiment, the multi-temperature zone temperature control mode includes:

detecting the first operating temperature of the first area and the second operating temperature of the second area;

Calculate the second difference between the first operating temperature and the first preset temperature, compare the second difference with the second preset difference, and when the second difference is greater than the second preset difference, control the first evaporator towards the first zone cooling;

Calculate the third difference between the second operating temperature and the second preset temperature, compare the third difference with the third preset difference, and when the third difference is greater than the third preset difference, control the second evaporator Toward the first zone of cooling.

In this embodiment, in the multi-temperature zone temperature control mode, the first evaporator and the second evaporator are individually controlled to cool the corresponding first zone and the second zone respectively. Wherein, the refrigerant is controlled to flow toward the first evaporator or the second evaporator through the valve, so that the first evaporator and the second evaporator respectively move toward the corresponding first area and the second area for cooling. Among them, the default temperature control mode of the direct cooling refrigeration device is the 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, it means that the first working temperature of the first area is too high, and the refrigerant is individually controlled to pass through the first The valve flows toward the first evaporator, cooling the first area; and when the second operating temperature does not reach the second preset temperature, the second difference is greater than the second preset difference, which means that the second area The second operating temperature is high, and the refrigerant is individually controlled to flow through the second valve toward the second evaporator to cool the second area.

Wherein, the first valve is connected to the first evaporator; the second valve is connected to the second evaporator. Preferably, the first valve and the second valve are solenoid valves, for example.

The first preset difference value and the second preset difference value are, for example, 2°C.

In addition, when the first difference is less than or equal to the first preset difference, the first valve is closed, and the first evaporator does not cool; similarly, when the second difference is less than or equal to the second preset difference, the second When the valve is closed, the second evaporator does not cool.

In addition, in the single temperature zone temperature control mode, if the first difference is less than the first preset difference, the first evaporator of the direct cooling refrigeration device is controlled to move toward the first zone for cooling or the second evaporator toward the second zone for cooling. The situation is similar to the multi-temperature zone temperature control mode, that is, at this time, the first preset temperature and the second preset temperature are consistent with the system set temperature respectively.

In a preferred embodiment, in the single temperature zone temperature control mode, if the first difference is greater than the first preset difference, the first evaporator and/or the second evaporator of the direct cooling refrigeration device are controlled respectively. The steps of cooling the corresponding first and second zones include:

Compare the first working temperature and the second working temperature with the system set temperature respectively;

If the first working temperature is consistent with the system set temperature, and the second working temperature is greater than the system set temperature, the second evaporator is controlled to cool the second area;

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 first evaporator is controlled to cool the first area.

In this embodiment, after the main control board detects the trigger signal, it enters the single temperature zone temperature control mode. 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 areas should not be too large.

Among them, by judging whether one of the first operating temperature and the second operating temperature reaches the system set temperature, and then controlling the operation of one of the first evaporator and the second evaporator, it is helpful to achieve energy saving while regulating the temperature. the goal of.

If the first difference is less than or equal to the system temperature difference set value, control the second evaporator to cool the second area, or control the second evaporator to stop cooling;

If the first difference is greater than the system temperature difference set value, the second evaporator is controlled to cool the second area, and the first evaporator is controlled to cool the first area.

In this embodiment, the relationship between the first difference between the first operating temperature and the second operating temperature and the system temperature difference set value is determined, where when the first difference is greater than the system temperature difference set value , it means that there is a large temperature difference 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 are The temperature reaches the system set temperature as soon as possible. Therefore, the second valve opens and the second evaporator cools the second area. At the same time, the first valve is kept open and the first area is cooled. The first area and the second area can be realized in a short time. The two areas reach the system set temperature together.

In addition, when the first difference is less than or equal to the system temperature difference set value, it means that the temperature difference between the first area and the second area is small, and the first operating temperature reaches the system set temperature. At this time, the second valve opens , the second evaporator cools the second area. Of course, when the first difference is small enough, it means that the second operating temperature is substantially close to the system set temperature. At this time, the second valve can also be closed and the second evaporator stops 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 cool the first area includes:

Compare the first difference value with the system temperature difference set value;

If the first difference is less than or equal to the system temperature difference set value, control the first evaporator to cool the first area, or control the first evaporator to stop cooling;

If the first difference is greater than the system temperature difference set value, the first evaporator is controlled to cool the first area, and the second evaporator is controlled to cool the second area.

In this embodiment, the relationship between the first difference between the first operating temperature and the second operating temperature and the system temperature difference set value is determined, where when the first difference is greater than the system temperature difference set value , it means that there is a large temperature difference 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 are The temperature reaches the system set temperature as soon as possible. Therefore, the first valve opens to cool the first area while keeping the second valve open. The second evaporator cools the second area, which can realize the first area and the second area in a short time. The areas reach the system set temperature together.

In addition, when the first difference is less than or equal to the system temperature difference set value, it means that the temperature difference between the first area and the second area is small, and the second operating temperature reaches the system set temperature. At this time, the first valve opens , the first evaporator cools the first area. Of course, when the first difference is small enough, it means that the first operating temperature is substantially close to the system set temperature. At this time, the first valve can also be closed and the first evaporator stops cooling.

In a preferred implementation, the first preset difference value and the system temperature difference setting value are different in numerical value. Preferably, the value of the first preset difference is greater than the system temperature difference set value.

In other embodiments of the present invention, if the first difference is greater than the first preset difference, the first evaporator and/or the second evaporator of the direct-cooling refrigeration device are controlled to face the corresponding respective directions. The step of cooling the first area and the second area also includes:

If the fourth difference is greater than the fourth preset difference, the second evaporator is controlled to cool the second area, and the first evaporator is controlled to cool the first area.

Wherein, when the difference between the fourth difference value and the fourth preset difference value is large, in order to prevent the high temperature in the second area from affecting the first area, the first and second evaporators are controlled while maintaining cooling until When the fourth difference falls within the fourth preset difference range, the first evaporator stops cooling; when the fourth difference reaches zero, the second evaporator stops cooling.

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 cool the first area includes:

Calculate the fifth difference between the first operating temperature and the system set temperature;

Compare the fifth difference value with the fifth preset difference value;
