It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
In the description of the present invention, it should be noted that the directions or positional relationships indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings, are merely for convenience of describing the present invention and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present invention.
The invention provides a temperature control method which is suitable for a direct cooling type refrigerating device, can intelligently regulate and control the temperatures of a plurality of areas of the direct cooling type refrigerating device, and particularly can realize that the working temperature of a first area is consistent with the working temperature of a second area after the direct cooling type refrigerating device enters a single temperature area from a plurality of temperature areas, thereby being beneficial to reducing the temperature difference of the refrigerating device.
As shown in fig. 1, a temperature control method 10 is applicable to a direct-cooling refrigeration apparatus, the direct-cooling refrigeration apparatus including a compartment, the compartment including a first region and a second region, and comprising:
judging whether a trigger switch in the direct-cooling refrigerating device is started or not:
if the trigger switch is started, executing a single-temperature-zone temperature control mode;
if the trigger switch is closed, executing a multi-temperature-zone temperature control mode;
wherein, single 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 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 value is larger than the first preset difference value, controlling the first evaporator and/or the second evaporator of the direct cooling type refrigerating device to respectively cool towards the corresponding first area and the second area.
In a preferred embodiment, the step of determining whether the trigger switch in the direct-cooled refrigeration apparatus 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 the temperature control method 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 temperatures 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.
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 larger 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 a third preset difference value, and controlling the second evaporator to refrigerate towards the first area when the third difference value is larger than the third 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 first difference value is smaller than or equal to a first preset difference value, the first valve is closed, and the first evaporator does not refrigerate; similarly, when the second difference is less 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 situation that the first evaporator of the direct-cooling refrigeration device cools towards the first zone or the second evaporator cools towards the second zone is controlled to be 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.
In a preferred embodiment, in the single temperature zone temperature control mode, if the first difference is greater than a first preset difference, the step of controlling the first evaporator and/or the second evaporator of the direct cooling refrigeration device to cool toward the corresponding first zone and second zone respectively includes:
comparing the first working temperature and the second working temperature with the set temperature of the system respectively;
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, controlling the second evaporator to refrigerate towards the second area;
and if the second working temperature is consistent with the system set temperature and the first working temperature is greater than the system set temperature, controlling the first evaporator to refrigerate towards the first area.
In this embodiment, after the main control board detects the trigger signal, the main control board enters a single-temperature-zone temperature control mode, and in this control mode, the space in the compartment is used as a whole, and the temperature of the first zone and the temperature of the second zone need to be controlled to be consistent, i.e. the temperature difference between the two zones is not too large.
And judging whether one of the first working temperature and the second working temperature reaches the set temperature of the system, and further controlling one of the first evaporator and the second evaporator to work, so that the purpose of energy saving is realized while the temperature is regulated and controlled.
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 cool toward the second area includes:
comparing the first difference value with a system temperature difference set value;
if the first difference value is smaller than or equal to the system temperature difference set value, controlling the second evaporator to refrigerate towards the second area, or controlling the second evaporator to stop refrigerate;
and if the first difference value is larger than the system temperature difference set value, 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 the magnitude relation between the first difference between the first operating temperature and the second operating temperature and the system temperature difference set value, where when the first difference is greater than the system temperature difference set value, it is indicated 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 reach the system set temperature as soon as possible, so that the second valve is opened, the second evaporator cools the second area, while maintaining the first valve open, and maintaining the cooling of the first area, 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 system temperature difference set value, the temperature difference between the first area and the second area is smaller, and the first working temperature reaches the system set temperature, at the moment, the second valve is opened, and the second evaporator refrigerates the second area. Of course, when the first difference is sufficiently small, it means that the second operating temperature is substantially close to the system set temperature, at which time the second valve may 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 toward the first area includes:
comparing the first difference value with a system temperature difference set value;
if the first difference value is smaller than or equal to the system temperature difference set value, controlling the first evaporator to refrigerate towards the first area, or controlling the first evaporator to stop refrigerate;
and if the first difference value is larger than the system temperature difference set value, 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 the magnitude relation between the first difference between the first operating temperature and the second operating temperature and the system temperature difference set value, where when the first difference is greater than the system temperature difference set value, it is indicated 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 reach the system set temperature as soon as possible, so that the first valve is opened, refrigeration is performed on the first area, while the second valve is maintained open, and the second evaporator is cooled on the second area, 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 system temperature difference set value, the temperature difference between the first area and the second area is smaller, and the second working temperature reaches the system set temperature, at the moment, the first valve is opened, and the first evaporator refrigerates the first area. Of course, when the first difference is sufficiently small, it means 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 stops cooling.
In a preferred embodiment, the first predetermined difference is different from the system temperature difference set point. 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 step of controlling the first evaporator and/or the second evaporator of the direct cooling refrigeration device to cool towards the corresponding first area and the second area respectively further includes:
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:
