Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of refrigeration equipment, in particular to a refrigeration equipment and a temperature control method and device thereof. BACKGROUND

[0002] For the refrigeration equipment of the single-temperature control cold system, taking a refrigerator as an example, the refrigerator has a low cost, but only has a refrigeration temperature sensor in a refrigeration compartment, and only has a freezing evaporator and a fan in a freezing compartment without a freezing temperature sensor. The refrigerator controls the start and stop of the compressor and the fan according to the temperature of the refrigeration compartment obtained by the temperature sensor in the refrigeration compartment, and the cold quantity of the freezing compartment is reached by the refrigeration system to achieve the refrigeration effect.

[0003] In the case of low ambient temperature, the refrigeration system has a low start rate because the refrigeration compartment does not need much cold quantity to maintain the temperature of the compartment, and the freezing compartment has a too high temperature to meet the actual freezing use demand because of the too low start rate, so the use environment has certain limitations or needs to increase a refrigeration compartment compensation heater to increase additional cost and process complexity. SUMMARY

[0004] The present application aims to at least solve one of the technical problems in the related art. To this end, the present application provides a temperature control method of a refrigeration equipment, which can increase the system start rate in a low ambient temperature and ensure the refrigeration temperature of the freezing compartment.

[0005] The present application also provides a temperature control device of a refrigeration equipment.

[0006] The present application also provides a refrigeration equipment.

[0007] The present application also provides an electronic equipment.

[0008] The present application also provides a non-transitory computer readable storage medium.

[0009] The first aspect embodiment of the present application provides a temperature control method of a refrigeration equipment, comprising:

[0010] determining that the ambient temperature is less than or equal to a preset temperature;

[0011] controlling the fan to intermittently operate at a first preset rotating speed;

[0012] in response to the freezing compartment meeting a freezing condition and the refrigeration compartment not reaching a shutdown point, controlling the fan to continuously operate at a second preset rotating speed;

[0013] wherein the second preset rotating speed is greater than the first preset rotating speed.

[0014] According to the temperature control method of the refrigeration equipment provided in the first aspect embodiment of the present invention, when the ambient temperature is low, the fan is intermittently operated at a relatively low first preset speed, that is, the fan is operated at the first preset speed for a first preset duration, and then the fan is turned off for a second preset duration, and the cycle is repeated according to this control mode. Since the fan is intermittently operated at a relatively low first preset speed, the temperature of the cold storage compartment cools down relatively slowly, thereby prolonging the time for the temperature in the cold storage compartment to reach the compressor shutdown point temperature. This prolongs the single start-up time of the compressor. Due to the increased start-up time, the compressor start-up rate can be increased, thereby further reducing the temperature of the freezer compartment. Specifically, due to the low ambient temperature, although the low-speed operation prolongs the cooling time, it does not cause the refrigerator compartment to cool down too slowly. Under normal circumstances, the refrigerator compartment still reaches the shutdown point quickly. However, to better suit another user scenario, such as when hot food is placed in the refrigerator compartment, the following situation arises: if the temperature of the freezer compartment meets the freezing conditions but the refrigerator compartment does not meet the refrigeration conditions, continuing to run the fan at the first preset speed would cause the refrigerator compartment temperature to cool down too slowly. Therefore, to avoid the refrigerator compartment temperature cooling down too slowly, the fan is run at a relatively higher second preset speed, which can quickly lower the temperature of the refrigerator compartment. In other words, this temperature control method can simultaneously take into account the cooling effect of both the freezer and refrigerator compartments. Furthermore, the temperature control method for the refrigeration equipment provided in the first aspect embodiment of the present invention effectively achieves the purpose of increasing the operating rate and ensuring the cooling temperature of the freezer and refrigerator compartments without increasing the cost of the refrigeration equipment.

[0015] According to one embodiment of the present invention, the step of responding to the freezing compartment meeting the freezing conditions and the refrigeration compartment not reaching the shutdown point includes:

[0016] Obtain the actual runtime of the compressor during this operation;

[0017] In response to the actual running time reaching the preset running time, it is determined that the freezer compartment meets the freezing conditions and the refrigerator compartment has not reached the shutdown point.

[0018] According to one embodiment of the present invention, the step of responding to the freezing compartment meeting the freezing conditions and the refrigeration compartment not reaching the shutdown point includes:

[0019] Obtain the actual cumulative duration of the intermittent operation of the fan during the current operation of the compressor;

[0020] In response to the actual cumulative duration reaching the preset cumulative duration, it is determined that the freezer compartment meets the freezing conditions and the refrigerator compartment has not reached the shutdown point.

[0021] According to one embodiment of the present invention, the step of controlling the fan to operate intermittently at a first preset speed includes:

[0022] The fan is operated at the first preset speed for a first preset duration, then the fan is turned off for a second preset duration, and the preset time is repeated.

[0023] According to one embodiment of the present invention, the first preset duration and the second preset duration are determined based on the temperature difference between the ambient temperature and the preset temperature, and the ratio of the first preset duration to the second preset duration is proportional to the magnitude of the temperature difference.

[0024] According to one embodiment of the present invention, after the step of controlling the fan to operate at a second preset speed, the method further includes:

[0025] Once the compressor's shutdown point is determined, the fan is shut down.

[0026] According to one embodiment of the present invention, it further includes:

[0027] Once the ambient temperature is determined to be higher than the preset temperature, the fan is operated at the third preset speed until the compressor stops.

[0028] The third preset rotational speed is greater than the first preset rotational speed.

[0029] A second aspect of the present invention provides a temperature control device for a refrigeration equipment, comprising:

[0030] The determination module is used to determine whether the ambient temperature is less than or equal to a preset temperature.

[0031] The first control module is used to control the fan to run intermittently at a first preset speed;

[0032] The second control module is used to control the fan to run continuously at a second preset speed in response to the freezing compartment meeting the freezing conditions and the refrigeration compartment not reaching the stop point.

[0033] The second preset speed is greater than the first preset speed.

[0034] The temperature control device for a refrigeration system provided in the second aspect of the present invention can effectively increase the compressor's operating rate, further reducing the temperature of the freezer compartment while also providing the refrigeration effect of the refrigerator compartment. Furthermore, the temperature control device for a refrigeration system provided in the second aspect of the present invention only requires existing equipment in the refrigeration system to effectively increase the operating rate, ensure the refrigeration temperature of the freezer and refrigerator compartments, and reduce costs.

[0035] A third aspect of the present invention provides a refrigeration device, comprising:

[0036] A processor, which executes a computer program to implement the steps of the temperature control method for the refrigeration device described above;

[0037] Temperature sensor, used to obtain ambient temperature;

[0038] The processor controls the fan based on the comparison between the ambient temperature and the preset temperature.

[0039] According to a third aspect of the refrigeration equipment provided by the present invention, by acquiring the ambient temperature and comparing it with a preset temperature, and based on the comparison result, the fan can be intermittently operated at a first preset speed, which can further reduce the temperature of the freezer compartment. When it is determined that the freezer compartment meets the freezing conditions but the refrigerator compartment does not meet the refrigeration conditions, the fan speed is adjusted to a second preset speed, which can avoid problems such as poor preservation effect caused by slow cooling of the refrigerator compartment. Alternatively, the fan can be controlled at a third preset speed based on the comparison result of the ambient temperature and the preset temperature, which can achieve rapid cooling, energy saving, and consumption reduction.

[0040] A fourth aspect of the present invention provides an electronic device, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the program to implement the steps of the temperature control method of the refrigeration device described above.

[0041] A fifth aspect of the present invention provides a non-transitory computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the steps of the temperature control method for the refrigeration device described above.

[0042] The above-described one or more technical solutions in the embodiments of the present invention have at least one of the following technical effects:

[0043] According to the temperature control method of the refrigeration equipment provided in the first aspect embodiment of the present invention, when the ambient temperature is low, the fan is intermittently operated at a relatively low first preset speed, that is, the fan is operated at the first preset speed for a first preset duration, and then the fan is turned off for a second preset duration, and the cycle is repeated according to this control mode. Since the fan is intermittently operated at a relatively low first preset speed, the temperature of the cold storage compartment cools down relatively slowly, thereby prolonging the time for the temperature in the cold storage compartment to reach the compressor shutdown point temperature. This prolongs the single start-up time of the compressor. Due to the increased start-up time, the compressor start-up rate can be increased, thereby further reducing the temperature of the freezer compartment. Specifically, due to the low ambient temperature, although the low-speed operation prolongs the cooling time, it does not cause the refrigerator compartment to cool down too slowly. Under normal circumstances, the refrigerator compartment still reaches the shutdown point quickly. However, to better suit another user scenario, such as when hot food is placed in the refrigerator compartment, the following situation arises: if the temperature of the freezer compartment meets the freezing conditions but the refrigerator compartment does not meet the refrigeration conditions, continuing to run the fan at the first preset speed would cause the refrigerator compartment temperature to cool down too slowly. Therefore, to avoid the refrigerator compartment temperature cooling down too slowly, the fan is run at a relatively higher second preset speed, which can quickly lower the temperature of the refrigerator compartment. In other words, this temperature control method can simultaneously take into account the cooling effect of both the freezer and refrigerator compartments. Furthermore, the temperature control method for the refrigeration equipment provided in the first aspect embodiment of the present invention effectively achieves the purpose of increasing the operating rate and ensuring the cooling temperature of the freezer and refrigerator compartments without increasing the cost of the refrigeration equipment.

[0044] Furthermore, the temperature control device for the refrigeration equipment provided according to the second aspect embodiment of the present invention can effectively increase the compressor's operating rate, thereby further reducing the temperature of the freezer compartment, while also achieving the refrigeration effect of the refrigerator compartment. In addition, the temperature control device for the refrigeration equipment provided in the second aspect embodiment of the present invention only requires the use of existing equipment in the refrigeration equipment to effectively increase the operating rate, ensure the refrigeration temperature of the freezer compartment and the refrigerator compartment, and reduce costs.

[0045] Furthermore, according to the refrigeration equipment provided in the third aspect embodiment of the present invention, by acquiring the ambient temperature and comparing it with a preset temperature, and based on the comparison result, the fan can be intermittently operated at a first preset speed, which can further reduce the temperature of the freezer compartment; when it is determined that the freezer compartment meets the freezing conditions but the refrigerator compartment does not meet the refrigeration conditions, the fan speed is adjusted to a second preset speed, which can avoid problems such as poor preservation effect caused by slow cooling of the refrigerator compartment. Alternatively, the fan can be controlled at a third preset speed based on the comparison result of the ambient temperature and the preset temperature, which can achieve the effects of rapid cooling, energy saving, and consumption reduction.

[0059] like Figure 1 As shown, a first aspect of the present invention provides a temperature control method for a refrigeration device, comprising:

[0060] Step 100: Determine that the ambient temperature is less than or equal to the preset temperature;

[0061] Step 200: Control the fan 408 to run intermittently at a first preset speed;

[0062] Step 300: In response to the freezer compartment 412 meeting the freezing conditions and the refrigerator compartment 410 not reaching the shutdown point, the fan 408 is controlled to run continuously at the second preset speed.

[0063] The second preset speed is greater than the first preset speed.

[0064] According to the temperature control method of the refrigeration equipment provided in the first aspect embodiment of the present invention, when the ambient temperature is low, the fan 408 is intermittently operated at a relatively low first preset speed, that is, the fan 408 is operated at the first preset speed for a first preset duration, and then the fan 408 is turned off for a second preset duration, and the preset time is cycled according to this control mode. Since the fan 408 is operated at a relatively low first preset speed, the temperature of the refrigerator compartment 410 drops relatively slowly, thereby prolonging the time for the temperature in the refrigerator compartment 410 to reach the shutdown point temperature of the compressor 404. This prolongs the single start-up time of the compressor 404. Due to the increased start-up time, the start-up rate of the compressor 404 can be increased, thereby further reducing the temperature of the freezer compartment 412. Specifically, due to the low ambient temperature, although the low speed operation prolongs the cooling time, it does not cause the refrigerator compartment 410 to cool down too slowly. Under normal circumstances, the refrigerator compartment 410 can still reach the shutdown point quickly. However, to better suit another user scenario, such as when hot food is placed in the refrigerator compartment 410, the following situation may occur: If it is determined that the freezer compartment 412 meets the freezing conditions and the refrigerator compartment 410 does not meet the refrigeration conditions, if the fan 408 continues to run at the first preset speed, the temperature of the refrigerator compartment 410 will cool down too slowly. Therefore, to avoid the refrigerator compartment 410 cooling down too slowly, the fan 408 is run at a relatively higher second preset speed. This can quickly lower the temperature of the refrigerator compartment 410. In other words, this temperature control method can simultaneously take into account the cooling effect of the freezer compartment 412 and the refrigerator compartment 410. Furthermore, the temperature control method for refrigeration equipment provided in the first aspect of the present invention effectively achieves the purpose of increasing the operating rate and ensuring the refrigeration temperature of the freezer compartment 412 and the refrigerator compartment 410 without increasing the cost of the refrigeration equipment.

[0065] Please refer to the above. Figure 1 and Figure 3Taking a refrigerator as an example of a refrigeration device, in step 100, the ambient temperature at the location of the refrigerator can be detected by a temperature detection element installed on the refrigerator, and the ambient temperature can be sent to the refrigerator's controller. After receiving the ambient temperature sent by the temperature detection element, the controller compares the ambient temperature at the location of the refrigerator with a preset temperature.

[0066] When the controller determines that the ambient temperature is greater than the preset temperature, it executes step 110 to run the fan 408 at the third preset speed until the compressor 404 stops.

[0067] Understandably, when the ambient temperature is higher than the preset temperature, the refrigerator compartment 410 and freezer compartment 412 will experience a temperature rise due to heat transfer from the external environment. At this time, the compressor 404 has normal start-stop requirements and a certain operating rate. Under this premise, the temperature of the freezer compartment 412 can reach the normal freezing temperature, such as -14 to -24 degrees Celsius, after cooling, and the temperature of the refrigerator compartment 410 can reach the normal refrigeration temperature, such as 4 to 8 degrees Celsius, after cooling.

[0068] For example, if the preset temperature is set to 8 degrees Celsius, and the ambient temperature detected by the temperature sensing element is 20 degrees Celsius, the refrigerator has normal cooling requirements. In this case, the controller can control the fan 408 to run at a third preset speed until the temperature in the refrigerator compartment 410 reaches the compressor 404's shutdown point. In this situation, both the refrigerator compartment 410 and the freezer compartment 412 can reach their normal target temperatures.

[0069] When the controller determines that the ambient temperature is less than or equal to the preset temperature, it executes step 200, controlling the fan 408 to run intermittently at a first preset speed; the intermittent operation mentioned here can be a method of running the fan 408 at the first preset speed for a first preset duration, then turning off the fan 408 for a second preset duration, and repeating the preset time.

[0070] It is understandable that when the ambient temperature is less than or equal to the preset temperature, if it is necessary to maintain the temperature of the refrigerator compartment 410 and the freezer compartment 412 at a lower temperature, it is necessary to ensure that the compressor 404 has a high operating rate to achieve the above purpose.

[0071] For example, if the preset temperature is set to 8 degrees Celsius, and the ambient temperature detected by the temperature detection element is 2 degrees Celsius, then to meet the cooling needs of the refrigerator compartment 410 and the freezer compartment 412, the compressor 404 needs to have a high operating rate.

[0072] Therefore, in step 200, the controller controls the fan 408 to run at a first preset speed for a first preset duration, and then controls the fan 408 to stop for a second preset duration. At the same time, the controller controls the fan 408 to cycle through the preset time in the above manner.

[0073] The first and second preset durations mentioned here can be selected according to actual cooling needs. In this embodiment of the invention, the first and second preset durations are determined based on the temperature difference between the ambient temperature and the preset temperature.

[0074] For example, if the preset temperature is set to 8 degrees, and the ambient temperature is 6 degrees, the temperature difference between the ambient temperature and the preset temperature is 2 degrees, then the first preset duration can be set to 5 minutes and the second preset duration can be set to 10 minutes; if the ambient temperature is 4 degrees, the temperature difference between the ambient temperature and the preset temperature is 4 degrees, then the first preset duration can be set to 5 minutes and the second preset duration can be set to 5 minutes.

[0075] As can be seen from the above example, the ratio of the first preset duration to the second preset duration is directly proportional to the temperature difference. That is, the greater the temperature difference between the ambient temperature and the preset temperature, the greater the ratio of the first preset duration to the second preset duration; conversely, the smaller the temperature difference between the ambient temperature and the preset temperature, the smaller the ratio of the first preset duration to the second preset duration.

[0076] The first preset speed mentioned above can be a relatively low speed, for example, the first preset speed can be 1000 revolutions per minute.

[0077] After the fan 408 cycles for the preset cycle time according to the above cycle method, step 300 is executed. In response to the fact that the freezer compartment 412 meets the freezing conditions and the refrigerator compartment 410 does not meet the refrigeration conditions, the fan 408 is controlled to run at the second preset speed.

[0078] In step 300, when the refrigerator determines that the temperature of the freezer compartment 412 has reached the target temperature while the temperature of the refrigerator compartment 410 has not reached the target temperature, the speed of the fan 408 is adjusted from a first preset speed to a second preset speed. The second preset speed is greater than the first preset speed; for example, the second preset speed could be 2500 revolutions per minute.

[0079] It should be noted that, for a single-system refrigerator, since the temperature sensor 406 is only installed in the refrigerator compartment 410, the temperature of the freezer compartment 412 cannot be directly obtained by measurement. Therefore, in this embodiment of the invention, determining that the temperature of the freezer compartment 412 has reached the target temperature while the refrigerator compartment 410 has not met the refrigeration conditions can be achieved in at least the following two different ways:

[0080] Method 1:

[0081] In this method, the actual running time of compressor 404 during this operation can be obtained, and the actual running time of compressor 404 can be compared with the preset running time to determine whether the temperature of the freezer compartment 412 has reached the target temperature.

[0082] In other words, once compressor 404 is turned on, its actual operating time is calculated. When the actual operating time of compressor 404 reaches the preset operating time, it indicates that sufficient cold air has flowed into the freezer compartment 412, meaning that the temperature of the freezer compartment 412 has reached the target temperature. However, since the refrigerator compartment 410 is opened and closed relatively frequently, and the amount of cold air flowing into the refrigerator compartment 410 is relatively small, when the actual operating time of compressor 404 reaches the preset operating time, it is determined that the refrigerator compartment 410 does not meet the refrigeration conditions.

[0083] Method 2:

[0084] In this method, the actual cumulative duration of the first preset duration and the second preset duration after the fan 408 cycles for a preset time can be obtained, that is, the actual cumulative duration of the intermittent operation of the compressor 404 in this operation, and the actual cumulative duration can be compared with the preset cumulative duration to determine whether the temperature of the freezer compartment 412 has reached the target temperature.

[0085] That is, after the fan 408 is turned on, the system immediately begins calculating the sum of the first preset time during which the fan 408 is turned on and the sum of the second preset time during which the fan 408 is turned off. This sum is then compared to the preset cumulative time. When the actual cumulative time reaches the preset cumulative time, it indicates that sufficient cold air has flowed into the freezer compartment 412, meaning that the temperature of the freezer compartment 412 has reached the target temperature. Similarly, since the refrigerator compartment 410 is opened and closed relatively frequently, and the amount of cold air flowing into it is relatively small, when the actual running time of the compressor 404 reaches the preset running time, it is determined that the refrigerator compartment 410 does not meet the refrigeration conditions.

[0086] Of course, in other embodiments, the temperature of the freezer compartment 412 can be determined to reach the target temperature in other ways, which will not be listed here.

[0087] When it is determined that the freezer compartment 412 meets the freezing conditions and the refrigerator compartment 41 does not meet the refrigeration conditions, the speed of the fan 408 is adjusted to the second preset speed.

[0088] The reason for this setup is that running the fan 408 at a first preset speed for a first preset time, then turning it off for a second preset time, and operating it through a cyclical control and preset cyclic mode, extends the operating time of the compressor 404 for a single refrigeration cycle. This increased operating time improves the compressor 404's operating rate, allowing the freezer compartment 412 to reach a lower cooling temperature. However, if the refrigerator compartment 410 hasn't reached refrigeration conditions yet, or if a user places relatively hot food into the refrigerator compartment 410, the temperature in the refrigerator compartment 410 will rise. If the fan 408 continues to operate at the relatively low first preset speed, the temperature in the refrigerator compartment 410 will not meet the actual cooling requirements. Furthermore, continuing to operate the fan 408 at the relatively low first preset speed will cause the temperature in the refrigerator compartment 410 to drop too slowly, making it difficult to ensure the normal operation of the refrigerator compartment 410's preservation function. Therefore, at this point, the speed of the fan 408 can be directly adjusted to the second preset speed, which is higher, so that the temperature of the refrigerator compartment 410 can be reduced quickly. Alternatively, the speed of the fan 408 can be adjusted to a speed greater than the second preset speed so that the temperature of the refrigerator compartment 140 can be reduced even more quickly.

[0089] According to one embodiment of the present invention, after the step of running the fan 408 at a second preset speed, the method further includes step 310, determining that the stop point of the compressor 404 has been reached and shutting down the fan 408.

[0090] In step 310, if the compressor 404 reaches its stop point, it proves that the temperature of the freezer compartment 412 and the refrigerator compartment 410 have reached the target temperature and can meet the normal refrigeration requirements. At this time, the fan 408 is turned off.

[0091] See Figure 2 A second aspect of the present invention provides a temperature control device for a refrigeration equipment, comprising:

[0092] Module 400 is used to determine whether the ambient temperature is less than or equal to a preset temperature.

[0093] The first control module 401 is used to control the fan 408 to run intermittently at a first preset speed;

[0094] The second control module 402 is used to control the fan 408 to run at a second preset speed in response to the freezing compartment 412 meeting the freezing conditions and the refrigerator compartment 410 not reaching the stop point.

[0095] The second preset speed is greater than the first preset speed.

[0096] The temperature control device for the refrigeration equipment provided according to the second aspect of the present invention can effectively increase the operating rate of the compressor 404, thereby further reducing the temperature of the freezer compartment 412, while also achieving the refrigeration effect of the refrigerator compartment 410. Furthermore, the temperature control device for the refrigeration equipment provided according to the second aspect of the present invention only requires the use of existing equipment in the refrigeration equipment to effectively increase the operating rate and ensure the refrigeration temperature of the freezer compartment 412 and the refrigerator compartment 410, thus reducing costs.

[0097] See Figure 3 A third aspect of the present invention provides a refrigeration device, comprising:

[0098] Processor 416 executes a computer program to implement the steps of the temperature control method for a refrigeration device as provided in the first aspect embodiment of the present invention.

[0099] Temperature sensor 406 is used to obtain ambient temperature;

[0100] The processor 416 controls the fan 408 based on the comparison between the ambient temperature and the preset temperature.

[0101] According to the refrigeration equipment provided in the third aspect embodiment of the present invention, by acquiring the ambient temperature and comparing it with a preset temperature, and based on the comparison result, the fan 408 can be operated intermittently at a first preset speed, which can further reduce the temperature of the freezer compartment 412. When it is determined that the freezer compartment 142 meets the freezing conditions but the refrigerator compartment 410 does not meet the refrigeration conditions, the speed of the fan 408 is adjusted to a second preset speed, which can avoid problems such as poor preservation effect caused by slow cooling of the refrigerator compartment 410. Alternatively, the fan 408 can be controlled at a third preset speed based on the comparison result of the ambient temperature and the preset temperature, which can achieve the effects of rapid cooling, energy saving, and consumption reduction.

[0102] According to one embodiment of the present invention, the refrigeration equipment includes a refrigerator compartment 410 and a freezer compartment 412, a temperature sensor 406 is disposed in the refrigerator compartment 410, and a freezer evaporator 414 and a fan 408 are disposed in the freezer compartment 412.

[0103] See Figure 3 A temperature sensor 406 is installed in the refrigerator compartment 410 to obtain the compartment temperature of the refrigerator compartment 410, and to determine whether the compressor 404 has reached its stop temperature based on the compartment temperature of the refrigerator compartment 410. A refrigeration evaporator 414 and a fan 408 are installed in the freezer compartment 412 to deliver cooling capacity to the freezer compartment 412 and the refrigerator compartment 410 through air ducts via the fan 408.
