Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0054] First, let's introduce the basic concepts related to the terms used in this invention:

[0055] Air-cooled refrigerator: An air-cooled refrigerator is a refrigerator that uses cold air to control the temperature. The principle is to use air for cooling. Specifically, when hot air flows through the built-in evaporator, the two exchange heat directly because the air temperature is high and the evaporator temperature is low. The air temperature will drop, thus becoming cold air. At the same time, the cold air is blown into the refrigerator through the air vent. Air-cooled refrigerators lower the refrigerator temperature through this continuous circulation.

[0056] This application provides a temperature control method, apparatus, and storage medium.

[0057] The temperature control method can be integrated into an electronic device, which can be a terminal device or a main control panel.

[0058] In some embodiments, the terminal can be a standalone device, such as a mobile phone, tablet computer, smart Bluetooth device, laptop computer, or personal computer (PC), etc., and the device can simultaneously function as a memory and a processor. The device serves as memory to store instructions, and simultaneously acts as a processor to load instructions from the memory to execute the temperature control method of the present invention. The device is connected to a temperature control device with temperature control functionality, transmitting the instructions to the temperature control device so that it can parse the instructions and execute the corresponding temperature control actions.

[0059] In some embodiments, the terminal may be a main control panel, which is used to realize human-computer interaction and is connected to a temperature control device with temperature control function. The main control panel may include a microprocessor, multiple controls, a display screen, etc. The controls are used to generate relevant operation instructions in response to user operations, so that the temperature control device can perform corresponding actions according to the operation instructions; the display screen is used to display various parameters generated when the temperature control device is working; the microprocessor may store the temperature control method of the present invention and generate corresponding temperature control instructions, so that the temperature control device can parse the instructions and execute corresponding temperature control actions.

[0060] In some embodiments, the temperature control method can also be integrated into multiple electronic devices. For example, the temperature control method can be integrated into multiple terminals, and the temperature control method of this application can be implemented by multiple terminals. Each terminal can implement different functions of the temperature control method.

[0061] In the embodiments of this application, the unit of temperature is set to ℃ (degrees Celsius). It is understood that the temperature value in this unit can be arbitrarily converted to other temperature units, and the specific temperature unit should not be construed as a limitation of the present invention.

[0062] The following sections provide detailed descriptions of each example. It should be noted that the sequence numbers of the following embodiments are not intended to limit the preferred order of the embodiments.

[0063] Example 1

[0064] refer to Figure 1a The diagram illustrates an application scenario of the temperature control method in this embodiment. For example... Figure 1a As shown, this embodiment may include a temperature control device 110 and a control main board 120. The temperature control device 110 includes an air damper 111 and a variable temperature chamber 112.

[0065] Specifically, the control motherboard 120 is connected to the temperature control device 110. The control motherboard 120 determines the temperature setting of the variable temperature chamber 112 in response to a user's operation to determine the temperature setting. This temperature setting reflects the upper limit of the target temperature at the highest point within the variable temperature chamber 112 after temperature control. The temperature control device 110 acquires the temperature setting information of the variable temperature chamber 112 and determines the target temperature range within that temperature setting. The temperature control device 110 determines a start temperature and a stop temperature based on the target temperature range. The start temperature is used to begin cooling the variable temperature chamber when the internal temperature is higher than the start temperature, and the stop temperature is used to stop cooling the variable temperature chamber when the internal temperature is lower than the stop temperature. The temperature control device 110 acquires the ambient temperature of the variable temperature chamber and determines the target opening angle of the damper 111 based on the ambient temperature. Finally, the temperature control device 110 performs temperature control on the variable temperature chamber based on the start temperature, the stop temperature, and the target opening angle.

[0066] In this embodiment, the description will focus on the temperature control device, which can be integrated into a temperature control system. This device is used to acquire the temperature setting information of the variable temperature chamber and determine the target temperature range of the temperature setting; determine the start-up temperature and stop temperature based on the target temperature range; acquire the ambient temperature of the variable temperature chamber and determine the target opening angle of the damper based on the ambient temperature; and perform temperature control on the variable temperature chamber based on the start-up temperature, the stop temperature, and the target opening angle.

[0067] The temperature control device can be an air-cooled refrigerator, or other temperature control devices including a variable temperature compartment and a damper.

[0068] like Figure 1b As shown, the flow of the temperature control method in this embodiment may include steps S110 to S150:

[0069] S110: Obtain the target temperature range of the temperature setting in the variable temperature chamber.

[0070] The variable temperature compartment is a storage space installed within a temperature control device. It can store items of a certain volume. The temperature control device adjusts the temperature within the variable temperature compartment to meet different user needs, such as refrigeration, preservation, and freezing. Users can set the temperature level of the variable temperature compartment via the main control panel or other terminal devices connected to the temperature control device. This temperature level reflects the target upper limit of the temperature inside the variable temperature compartment after temperature control; that is, the temperature in all locations within the variable temperature compartment should be lower than the set temperature level after temperature control is completed. Typically, the selectable range of the temperature levels will vary depending on the temperature control performance of the temperature control device. In some embodiments, the temperature range can be determined according to the user's actual needs. For example, the temperature level for refrigeration can be controlled within the range of 1–8°C, while the temperature level for freezing can be controlled below -18°C.

[0071] S120. Determine the start-up temperature and stop temperature based on the target temperature range.

[0072] The start-up temperature is used by the temperature control device to determine whether to start cooling the variable temperature chamber based on its specific value. Similarly, the stop temperature is used by the temperature control device to determine whether to stop cooling the variable temperature chamber based on its specific value. Generally, for a variable temperature chamber with a pre-set temperature range, the start-up temperature should be higher than the set temperature range, and the stop temperature should be lower than the set temperature range, thereby ensuring that the average internal temperature of the variable temperature chamber after temperature control operation is approximately equal to the set temperature range.

[0073] In some embodiments, the process of determining the start-up temperature and the stop temperature based on the target temperature range may include a process of determining start-up parameters and stop parameters, as follows:

[0074] S121. Determine the start-up and stop parameters based on the target temperature range;

[0075] S122. Determine the starting temperature based on the temperature setting and the starting parameters;

[0076] S123. Determine the stop temperature based on the temperature setting and the stop parameters.

[0077] The start-up and stop-down parameters can be integers. Based on these parameters, the start-up temperature can be obtained by adding the temperature setting to the start-up parameter; similarly, the stop-down temperature can be obtained by subtracting the stop-down parameter from the temperature setting. For example, when the temperature setting is set to 5°C, it can be considered to be within the temperature range intended for refrigeration. In this case, both the start-up and stop-down parameters can be set to 1°C, thus calculating the start-up temperature to 6°C and the stop-down temperature to 4°C. It is understood that other calculation methods can also be used to determine the start-up and stop-down temperatures. Under different calculation methods, the start-up and stop-down parameters will also change accordingly. The specific calculation method and parameter values ​​should not be construed as limiting the invention.

[0078] In some embodiments, the correspondence between the start-up parameters and the stop parameters and the target temperature range is determined through controlled variable experiments. For example, under the condition that the power of the chiller, the air volume of the damper, the outdoor temperature and other factors remain unchanged, with energy consumption and cooling efficiency as the targets, the optimal start-up parameters and stop parameters under a certain target temperature range are obtained by repeatedly testing and taking the average value, and then the start-up temperature and stop temperature are determined according to the preset algorithm.

[0079] In the above embodiments, by setting reasonable parameters and algorithms to determine the start-up and stop temperatures, it can be ensured that the temperature control device can achieve temperature control of the variable temperature chamber with high cooling efficiency and low energy consumption under different temperature ranges.

[0080] In some embodiments, the process of determining the start-up parameters and stop-down parameters based on the target temperature range may include the following multiple temperature range judgment conditions A1 to A3, where different temperature ranges correspond to different start-up parameters and stop-down parameters:

[0081] A1. If the target temperature range is the first temperature range, then the start parameter is determined to be the first start parameter, and the stop parameter is determined to be the first stop parameter;

[0082] A2. If the target temperature range is the second temperature range, then the start parameter is determined to be the second start parameter, and the stop parameter is determined to be the second stop parameter, wherein the upper limit of the second temperature range is less than the lower limit of the first temperature range.

[0083] A3. If the target temperature range is the third temperature range, then the start parameter is determined to be the third start parameter, and the stop parameter is determined to be the third stop parameter, wherein the upper limit of the third temperature range is less than the lower limit of the second temperature range.

[0084] The relationship between the first, second, and third temperature ranges is as follows: the upper limit of the second temperature range is less than the lower limit of the first temperature range, and the upper limit of the third temperature range is less than the lower limit of the second temperature range. Specifically, the first, second, and third temperature ranges can be obtained by inserting two discontinuities within a closed interval representing temperature. For example, using the letter 't' to represent the temperature setting, the first temperature range could be 0℃ < t ≤ 8℃, the second temperature range could be -14℃ ≤ t ≤ 0℃, and the third temperature range could be -18℃ ≤ t < -14℃. That is, the above three temperature ranges are obtained by inserting two discontinuities, 0℃ and -14℃, within the temperature range of -18℃ ≤ t ≤ 8℃. It is understood that, provided the relevant cooling requirements are met, the number of temperature ranges within which the temperature setting is located is determined by factors such as the performance of the temperature control equipment and actual usage needs, and should not be construed as a limitation of the present invention.

[0085] The process of determining the temperature range of the temperature setting can be as follows: First, determine if the temperature setting belongs to the third temperature range, then the second temperature range, and finally the first temperature range. Specifically, first, determine if the temperature setting is in the third temperature range. If the condition is met, determine the start and stop parameters as the third start and stop parameters, respectively. If the condition is not met, determine if the temperature setting is in the second temperature range. If the condition is met, determine the start and stop parameters as the second start and stop parameters, respectively. Otherwise, determine the start and stop parameters as the first start and stop parameters, respectively. Alternatively, it can be done by directly determining that the temperature setting falls within a certain temperature range, and then determining the corresponding start and stop parameters based on that temperature range. The order and method of determining the temperature range are determined by the design of the temperature control equipment and should not be construed as a limitation of the present invention.

[0086] In some embodiments, when the start-up temperature is calculated by adding a start-up parameter to the temperature setting, and the stop temperature is calculated by subtracting a stop parameter from the temperature setting, the relationship between the first start-up parameter, the second start-up parameter, and the third start-up parameter is: third start-up parameter < second start-up parameter < first start-up parameter; while the relationship between the first stop parameter, the second stop parameter, and the third stop parameter is: first stop parameter < second stop parameter < third stop parameter. For example, the first start-up parameter, the second start-up parameter, and the third start-up parameter can be 1℃, 0℃, and -1℃, respectively, and the first stop parameter, the second stop parameter, and the third stop parameter can be 1℃, 2℃, and 3℃, respectively. Under the premise that other factors remain unchanged, changes in the start-up parameter and the stop parameter can directly change the start-up temperature and the stop temperature, thereby changing the cooling time of the variable temperature chamber by the temperature control equipment and affecting the cooling efficiency.

[0087] In the above embodiments, by setting different parameters for different temperature ranges, the temperature control method can achieve effective temperature control under various conditions, thereby improving the efficiency of temperature control.

[0088] In some embodiments, after determining that the start-up parameter is a third start-up parameter and the stop parameter is a third stop parameter, the temperature control method further includes a first time threshold determination process, specifically including the following steps B1 to B2:

[0089] B1. Determine whether the duration of the temperature setting being in the third temperature range reaches a first time threshold.

[0090] B2. When the duration reaches the first time threshold, the start parameter is updated to the fourth start parameter, and the stop parameter is updated to the fourth stop parameter.

[0091] The first time threshold is a preset specific time value, which can be 12h, 24h, 48h, etc., determined by actual usage requirements. In some embodiments, when the start-up temperature is calculated by adding the start-up parameter to the temperature setting, and the stop temperature is calculated by subtracting the stop parameter from the temperature setting, the other start-up parameters still satisfy the numerical relationships described above. In this case, the fourth start-up parameter < the third start-up parameter, and the fourth stop parameter > the third stop parameter.

[0092] At this point, since the temperature setting is in the third temperature range, which is known to correspond to the temperature range with the lowest average temperature, if the duration of the temperature setting within this range exceeds the preset first time threshold, it can be assumed that the variable temperature chamber has a high load and a high cooling requirement. If the third start-up parameter and the third stop-down parameter are used in this situation, the temperature setting requirement may not be guaranteed, meaning the temperature at the highest point in the variable temperature chamber may exceed the set temperature setting. Therefore, the start-up and stop-down parameters need to be updated. When the start-up temperature is calculated by adding the start-up parameter to the temperature setting, and the stop-down temperature is calculated by subtracting the stop-down parameter from the temperature setting, the updated fourth start-up parameter is less than the third start-up parameter, and the fourth stop-down parameter is greater than the third stop-down parameter, thus reducing the start-up and stop-down temperatures accordingly. For example, the third start parameter and the third stop parameter are -1℃ and 3℃ respectively, and the fourth start parameter and the fourth stop parameter can be -2℃ and 4℃ respectively. If the temperature setting is set to -18℃, the start temperature is updated from -19℃ to -20℃, and the stop temperature is updated from -21℃ to -22℃. Lower start and stop temperatures can ensure that the temperature-controlled variable temperature chamber meets the temperature setting requirements under high load conditions.

[0093] In the above embodiments, by determining that the time the gear setting is in the lowest temperature range exceeds a certain threshold, and then updating the start and stop parameters, it can be ensured that under high load conditions, the temperature control device can meet the user's actual cooling needs after controlling the temperature of the variable temperature compartment.

[0094] S130: Obtain the ambient temperature of the variable temperature chamber.

[0095] In this context, compared to the internal temperature of the variable temperature chamber, which is typically below 10°C, the ambient temperature refers to the external environmental temperature of the variable temperature chamber, which is usually the atmospheric temperature experienced by residents in their daily lives. In some embodiments, the external ambient temperature of the variable temperature chamber can be determined by measuring the temperature of the external environment where the temperature control equipment is located.

[0096] It is understood that there are various methods to obtain the ambient temperature of the variable temperature chamber. For example, a temperature sensor can be installed outside the variable temperature chamber or temperature control equipment. This temperature sensor is used to detect the specific value of the ambient temperature in real time and accurately, so as to facilitate subsequent steps of the temperature control method based on the ambient temperature. The temperature sensor can be a metal temperature sensor, a glass liquid temperature sensor, an NTC (Negative Temperature Coefficient) temperature sensor, etc., and the type of temperature sensor should not be construed as a limitation of the present invention. Alternatively, the ambient temperature of the variable temperature chamber can be obtained by connecting the temperature control equipment to a temperature measuring device, allowing the temperature control equipment to receive the ambient temperature information measured by the temperature measuring device. The specific method for obtaining the ambient temperature of the variable temperature chamber should not be construed as a limitation of the present invention.

[0097] S140. Determine the target opening angle of the damper based on the ambient temperature.

[0098] The damper is a device in the temperature control equipment used to control the air supply volume. The damper includes an air outlet and a rotatable damper plate. The temperature control equipment can control the air supply volume by controlling the damper plate to rotate by a specified angle to change the area of ​​the air outlet. For example, the temperature control equipment may include a stepper motor connected to the damper. The temperature control equipment controls the forward / reverse rotation of the damper plate by controlling the running time of the stepper motor. The longer the running time, the larger the rotation angle. Forward rotation of the damper plate increases the area of ​​the air outlet, while reverse rotation decreases the area of ​​the air outlet until the area of ​​the air outlet is zero, at which point the damper is closed. In some embodiments, the rotation angle of the damper plate can be any value between 0° and 90°. 0° indicates that the damper is closed, at which point the area of ​​the air outlet is 0, the air supply volume is 0, and the temperature control equipment does not cool the variable temperature compartment. 90° indicates that the area of ​​the air outlet has reached its upper limit, and under the condition that other factors remain unchanged, the cooling efficiency of the temperature control equipment for the variable temperature compartment reaches its maximum value under the current conditions.

[0099] In some embodiments, the process of determining the target opening angle of the damper based on the ambient temperature may include steps S141 to S143 of determining the target opening angle across multiple temperature ranges:

[0100] S141. If the ambient temperature is within the fourth temperature range, then the target opening angle is determined to be the first opening angle.

[0101] S142. If the ambient temperature is within the fifth temperature range, the target opening angle is determined to be the second opening angle, wherein the upper limit of the fifth temperature range is less than the lower limit of the fourth temperature range.

[0102] S143. If the ambient temperature is within the sixth temperature range, the target opening angle is determined to be the third opening angle, wherein the upper limit of the sixth temperature range is less than the lower limit of the fifth temperature range.

[0103] The fourth, fifth, and sixth temperature ranges are related in that the upper limit of the fifth temperature range is less than the lower limit of the fourth temperature range, and the upper limit of the sixth temperature range is less than the lower limit of the fifth temperature range. For example, using the letter T to represent ambient temperature, the fourth temperature range could be 35℃ ≤ T, the fifth temperature range could be 18℃ ≤ T < 35℃, and the sixth temperature range could be T < 18℃. It is understood that the number of temperature ranges within which the ambient temperature falls is determined by factors such as actual usage requirements and should not be construed as a limitation of this invention.

[0104] In some embodiments, since the average temperature values ​​in the fourth, fifth, and sixth temperature ranges decrease sequentially, and the higher the ambient temperature, the higher the cooling efficiency required for the variable temperature compartment to ensure that items placed in the variable temperature compartment from the external environment can be cooled down in a timely manner, the first, second, and third opening angles also decrease sequentially. For example, if the rotation angle of the damper can be any value between 0° and 90°, the first opening angle can be 90°, the second opening angle can be 60°, and the third opening angle can be 10°. The larger the angle, the greater the air volume and the higher the cooling efficiency.

[0105] The determination of the temperature range in which the ambient temperature falls can be analogous to the determination order and method of the temperature range in which the temperature setting falls, and will not be elaborated here.

[0106] In the above embodiments, by setting different temperature ranges corresponding to different target opening angles, the cooling efficiency can be effectively controlled, ensuring that the temperature control method can achieve effective temperature control under various ambient temperature conditions.

[0107] Furthermore, in some embodiments, a weight sensor is installed in the variable temperature chamber, and the process of determining the target opening angle of the damper based on the ambient temperature includes the following steps S144 to S145:

[0108] S144. Receive and parse the weight data information transmitted by the weight sensor, the weight data information being used to reflect the weight of the items in the variable temperature chamber;

[0109] S145. When the weight of the items in the variable temperature chamber is higher than a preset weight threshold, the target opening angle of the damper is determined based on the weight of the items and the external ambient temperature.

[0110] The weight sensor is a device that converts a mass signal into a measurable electrical signal output. Typically, the weight sensor installed in the variable temperature compartment is a pressure-type weight sensor, which converts the mass information of the items inside the compartment into an electrical signal. By analyzing this electrical signal, the mass of the items inside the compartment can be determined. A larger mass of items inside the compartment indicates a higher load on the compartment. In this case, the target opening angle of the damper needs to be increased within the damper's angle limit to ensure that the cooling efficiency meets the requirements.

[0111] S150. The temperature of the variable temperature chamber is controlled according to the start-up temperature, the stop temperature and the target opening angle.

[0112] In some embodiments, such as Figure 2As shown, the temperature control of the variable temperature chamber based on the start-up temperature, the stop temperature, and the target opening angle specifically includes the following steps S151 to S153:

[0113] S151. Obtain the internal temperature of the variable temperature chamber;

[0114] S152. When the internal temperature is greater than the start-up temperature, control the damper to deliver air for cooling at the target opening angle;

[0115] S153. When the internal temperature is lower than the stop temperature after being cooled by air supply, the damper is closed.

[0116] It is understood that there are various methods for obtaining the internal temperature of the variable temperature chamber. For example, a temperature sensor is installed inside the variable temperature chamber, and the temperature control device determines the specific value of the internal temperature by analyzing the temperature information transmitted by the temperature sensor.

[0117] In some embodiments, after determining the start-up temperature and the stop temperature based on the target temperature range, the temperature control method further includes: determining the operating power of the refrigerator based on the start-up temperature.

[0118] The chiller controls the airflow rate through the damper per unit time. Under otherwise constant conditions, a higher chiller power results in a higher airflow rate and higher cooling efficiency; conversely, a lower chiller power results in a lower airflow rate and lower cooling efficiency. Clearly, a lower start-up temperature requires a higher cooling efficiency for the variable temperature compartment, ensuring the temperature inside drops to the stop temperature as quickly as possible to meet user needs.

[0119] Based on the above-mentioned variation of operating power with startup temperature, the cooling process can be determined jointly by the startup temperature, the shutdown temperature, the target opening angle, and the operating power. Specifically, as follows: Figure 3 As shown: First, the temperature setting of the variable temperature chamber is obtained, and the opening and stopping parameters are determined based on the temperature setting. If the temperature setting remains in the lowest temperature range for more than a certain time threshold, the opening and stopping parameters are updated. Then, the starting temperature and stopping temperature are calculated based on the opening and stopping parameters. The operating power is determined based on the starting temperature. When the internal temperature of the variable temperature chamber is higher than the starting temperature, the ambient temperature is obtained, and the target opening angle is determined based on the ambient temperature. After all factors are determined, the variable temperature chamber is cooled according to the operating power and the target opening angle. When the internal temperature of the variable temperature chamber is lower than the stopping temperature, the refrigeration unit and the damper are turned off.

[0120] In the above embodiments, by combining the start-up temperature with the operating power of the chiller, variable speed control of the operating power is achieved, thereby ensuring that the temperature control equipment can perform cooling with appropriate efficiency under specific conditions, meeting both cooling requirements and low energy consumption requirements.

[0121] In some embodiments, after controlling the temperature of the variable temperature chamber based on the start-up temperature, the stop temperature, the target opening angle, and the operating power, the temperature control method further includes a variable-speed cooling process based on changes in the internal temperature, specifically including the following processes C1 to C2:

[0122] C1. Determine whether the absolute value of the temperature difference between the internal temperature and the stop temperature is less than a preset temperature difference threshold.

[0123] C2. When the temperature difference is less than the preset temperature difference threshold, the operating power is updated to the corrected operating power and the temperature of the variable temperature chamber is controlled.

[0124] The temperature threshold can be a fixed value or different thresholds can be set according to different temperature ranges of the temperature setting. For example, when the temperature setting is set to 5℃, it falls within the first temperature range of 0℃ < t ≤ 8℃. The corresponding start-up temperature is 6℃, the stop temperature is 4℃, and the temperature difference threshold can be 1℃. That is, when the internal temperature is above 5℃, cooling is performed according to the original operating power; when the internal temperature is below 5℃ but above 4℃, cooling is performed at a modified operating power. The modified operating power is lower than the operating power, and operating at lower power can save energy.

[0125] In the above embodiments, by setting a temperature difference threshold, it is ensured that after the temperature in the variable temperature chamber reaches the set temperature, subsequent cooling is carried out with lower power, thereby meeting the user's cooling needs while achieving low energy consumption of the temperature control equipment.

[0126] In this embodiment of the invention, by setting appropriate start-up parameters, stop-up parameters, and target start-up angle, the cooling efficiency is precisely selected in two directions: cooling time and cooling power. This ensures that the temperature control device can perform cooling in a high-efficiency and low-energy-consumption manner under different temperature levels and ambient temperature conditions.
