[0016] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0017] In the related art, a refrigeration system generally includes a cold storage module and a refrigeration module for refrigerating the cold storage module. The cold storage module includes a cold storage container, a cooling medium disposed in the cold storage container, and a water pump for stirring the cooling medium.

[0018] The cold storage container is filled with a cooling medium, and the refrigeration module is partially immersed in the cooling medium to cool the cooling medium; the heat exchange tube exchanges heat with the cooling medium to output low-temperature water.

[0019] Cold storage containers usually use ice storage to store cold energy. If the temperature inside the cold storage container is uneven, the refrigeration module will continue to cool, causing the local temperature of the heat exchange tube to be too low, resulting in local ice blockage in the heat exchange tube, which can easily cause machine failure.

[0020] Specifically, the load on the cooling module varies with the temperature inside the cold storage container. If the inlet water temperature is high or the ambient temperature is high, the water pump will churn during cooling, causing the temperature around the cooling system to drop slowly. Continuous operation of the cooling system can easily lead to excessive load and trigger overload protection.

[0021] However, if the water pump does not work, when the water inlet temperature of the cold storage container is high or the ambient temperature is high, the temperature difference in the cold storage container is large, and when the temperature around the heat exchange tube is low, the heat exchange tube is prone to ice blockage.

[0022] To address the aforementioned issues, the inventors have proposed an anti-icing control method, device, refrigeration equipment, and storage medium. The anti-icing control method is applied to a refrigeration system comprising a cold storage module and a refrigeration module for cooling the cold storage module. The cold storage module comprises a cold storage container, a cooling medium disposed in the cold storage container, and a water pump for stirring the cooling medium. The anti-icing control method includes: obtaining the real-time temperature of the cooling medium; and when the real-time temperature is less than a first preset temperature and greater than or equal to a second preset temperature, controlling the water pump to operate according to a target start-stop ratio. The first preset temperature is greater than a second preset temperature; the second preset temperature is greater than a third preset temperature; the first preset temperature is the load threshold temperature of the cooling system; and the third preset temperature is the ice-forming layer temperature of the cooling system. When the cooling system detects that the cooling medium temperature is high, that is, when the real-time temperature is between the load threshold temperature and the second preset temperature, the cooling system controls the water pump to operate according to the target start-stop ratio. This method can alleviate ice blocking caused by uneven temperature within the cold storage container during the cooling phase before the ice-forming layer is formed, reducing the probability of refrigeration system failure, and simultaneously reducing the workload of the cooling system and increasing the service life of the cooling system.

[0023] The following describes the application environment of the anti-icing and blocking control method provided by the embodiment of the present invention.

[0024] See also Figure 1 The anti-icing and blocking control method provided in the embodiment of the present invention can be applied to the refrigeration system 100. The refrigeration system 100 can be applied to a water dispenser, a sparkling water dispenser, or other refrigeration equipment with a refrigeration function, and this application does not limit this.

[0025] In the embodiments of the present application, Figure 1 As shown, the refrigeration system 100 includes a cold storage module 120 and a refrigeration module 110 for refrigerating the cold storage module 120. The cold storage module 120 includes a cold storage container 121, a cooling medium disposed in the cold storage container 121, and a water pump 123 for stirring the cooling medium.

[0026] In some embodiments, the refrigeration module 110 may include a compressor 111, a condenser 113, and an evaporator 115. The compressor 111, the condenser 113, and the evaporator 115 are sequentially connected to form a refrigeration cycle. The evaporator 115 is disposed within the cold storage container 121 and partially or completely immersed in the cooling medium to cool the cooling medium.

[0027] In some embodiments, the cooling medium may be water or other refrigerants.

[0028] In some embodiments, the refrigeration system 100 may include a temperature detector 130. The temperature detector 130 sensor can be used to detect the real-time temperature of the cooling medium. The temperature detector 130 can be an NTC (Negative Temperature Coefficient) temperature sensor, an infrared temperature sensor, etc. The specific selection can be based on actual use needs and is not limited here.

[0029] In some embodiments, the refrigeration system 100 may include a water pipe 140, and a portion of the water pipe 140 may be coiled to form a heat exchange pipe 141. The heat exchange pipe 141 is immersed in the cooling medium. When water flows through the water pipe 140, it can exchange heat with the cooling medium through the wall of the heat exchange pipe 141 when passing through the heat exchange pipe 141, thereby outputting low-temperature water.

[0030] In some embodiments, the refrigeration system 100 may include a water inlet pipe 150 and a drain pipe 160. One end of the water inlet pipe 150 is connected to the cold storage container 121 and is used to provide cooling medium to the cold storage container 121. One end of the drain pipe 160 is connected to the cold storage container 121 and is used to discharge the cooling medium in the cold storage container 121 when the refrigeration system 100 is not used for a long time.

[0031] In some embodiments, the refrigeration system 100 may include a controller, which may be connected to the temperature detector 130. The controller may be configured to control the start and stop of the cold storage module 120 and the refrigeration module 110 based on the real-time temperature detected by the temperature detector 130. Specifically, the controller may be configured to control the start and stop of the water pump 123 and the compressor 111 based on the real-time temperature detected by the temperature detector 130. The controller may be an MCU (Microcontroller Unit), an MPU (Microprocessor Unit), a CPU (Central Processing Unit), or the like.

[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0033] like Figure 2 As shown, Figure 2 A flow chart of an anti-icing and blocking control method provided in an embodiment of the present invention is shown. The anti-icing and blocking control method can be applied to the above-mentioned refrigeration system. The method includes: steps 210 to 220.

[0034] Step 210: Acquire the real-time temperature of the cooling medium.

[0035] The cooling medium may be water or other refrigerants.

[0036] In some embodiments, the real-time temperature of the cooling medium can be detected by a temperature detector.

[0037] During the operation of the refrigeration system, the temperature of the cooling medium can be regularly collected as the real-time temperature according to a preset sampling interval.

[0038] Step 220: When the real-time temperature is lower than the first preset temperature and the real-time temperature is higher than or equal to the second preset temperature, the water pump is controlled to operate according to the target start-stop ratio.

[0039] Among them, the first preset temperature is greater than the second preset temperature; the second preset temperature is greater than the third preset temperature; the first preset temperature is the load critical temperature of the refrigeration system; and the third preset temperature is the ice-making layer temperature of the refrigeration system.

[0040] In some embodiments, the first preset temperature, the second preset temperature, and the third preset temperature can be preset according to actual needs.

[0041] In some embodiments, when the real-time temperature is greater than or equal to the load critical temperature, the load of the refrigeration module is large. In order to reduce the load of the refrigeration module, the water pump can be controlled to stop working.

[0042] In some embodiments, when the real-time temperature is lower than the ice-making layer temperature, the cold storage module can make an ice layer. In order to prevent excessive ice from forming in the cold storage module, the water pump can be started and stopped intermittently to ensure the thickness of the ice layer. The time of intermittent start and stop can be preset according to demand. In some embodiments, when the real-time temperature is lower than the first preset temperature and greater than or equal to the second preset temperature, the refrigeration module is still under a large load (the load is lower than the load in the stage where the real-time temperature is greater than or equal to the first preset temperature). At the same time, the temperature of the cooling medium is on a downward trend, and the temperature in the cold storage module is uneven, which can easily lead to local ice blockage. To this end, the technical solution provided in the embodiment of the present application controls the water pump to work according to the target start and stop ratio when the real-time temperature is lower than the first preset temperature and the real-time temperature is greater than or equal to the second preset temperature, thereby preventing the refrigeration module from being overloaded and improving the problem of uneven temperature in the cold storage module.

[0043] In some embodiments, the target start-stop ratio can be pre-set according to actual needs. The target start-stop ratio can be a fixed value or a variable value, and can be adjusted according to actual use needs.

[0044] Furthermore, in order to more accurately control the load of the refrigeration module within a reasonable range and improve the refrigeration efficiency under the premise of stable system operation, the temperature range between the first preset temperature and the second preset temperature can be further subdivided. When the real-time temperature is in different temperature ranges, the water pump is controlled to work according to different start-stop ratios.

[0045] As an example, the first preset temperature is set to 30°C, the second preset temperature is set to 10°C, and the third preset temperature is set to 1°C.

[0046] When the temperature detector detects that the real-time temperature of the cooling medium is greater than 30°C, the water pump stops working.

[0047] When the temperature detector detects that the real-time temperature of the cooling medium is less than 1°C, the water pump operates in an intermittent start-stop mode. For example, the water pump starts for 1 minute and stops for 3 minutes; for another example, the water pump starts for 2 minutes and stops for 4 minutes.

[0048] When the temperature detector detects that the real-time temperature of the cooling medium is between 10°C and 30°C, the refrigeration system controls the water pump to operate according to the target start-stop ratio. For example, the real-time temperature is 11°C, 13°C, 18°C, 20°C, 25°C, 29°C, etc. Further, the temperature interval [10, 30) can be subdivided into multiple different temperature intervals. For example, the temperature interval [10, 30) can be divided into two temperature intervals with different temperature differences [10, 15) and [15, 30). Then:

[0049] When the real-time temperature is in the temperature range [10, 15), the refrigeration system controls the water pump to work according to the target start-stop ratio of 1 / 3. For example, the controller controls the water pump to work according to the start time of 1 minute and the stop time of 3 minutes.

[0050] When the real-time temperature is in the temperature range [15, 30), the refrigeration system controls the water pump to work according to the target start-stop ratio of 2 / 3. For example, the controller controls the water pump to work according to the start time of 2 minutes and the stop time of 3 minutes.

[0051] As another example, the first preset temperature is set to 30°C and the second preset temperature is set to 10°C. The temperature interval [10, 30) is divided into multiple temperature intervals [10, 15), [15, 20), [20, 25), and [25, 30) with the same temperature difference. Then:

[0052] When the real-time temperature is in the temperature range [25, 30), the refrigeration system controls the water pump to work according to the target start-stop ratio of 1 / 5. For example, the controller controls the water pump to work according to the time of starting for 1 minute and stopping for 5 minutes.

[0053] When the real-time temperature is in the temperature range [20, 25), the refrigeration system controls the water pump to work according to the target start-stop ratio of 2 / 5. For example, the controller controls the water pump to work according to the time of starting for 1 minute and stopping for 5 minutes.

[0054] When the real-time temperature is in the temperature range [15, 20), the refrigeration system controls the water pump to work according to the target start-stop ratio of 3 / 5. For example, the controller controls the water pump to work according to the start time of 3 minutes and the stop time of 5 minutes.

[0055] When the real-time temperature is in the temperature range [10, 15), the refrigeration system controls the water pump to work according to the target start-stop ratio of 4 / 5. For example, the controller controls the water pump to work according to the start time of 4 minutes and the stop time of 5 minutes.

[0056] It should be noted that the values for temperature, start-stop ratio, and start-stop time in the above examples are provided as examples only for ease of understanding. Furthermore, when subdividing the temperature range between the first preset temperature and the second preset temperature, it can be divided into multiple temperature ranges with equal or different temperature differences. The start-stop ratios can be set to the same or different ratios, and can be set based on actual needs, which is not limited in the present invention.

[0057] In some embodiments, when the temperature interval between the first preset temperature and the second preset temperature is subdivided, the more subdivided temperature intervals there are, the more accurately the start and stop time of the water pump can be adjusted according to the real-time temperature, so as to control the load of the refrigeration system within a more reasonable range, thereby improving the refrigeration efficiency of the refrigeration system.

[0058] In some embodiments, the step in step 220 includes the following steps: controlling the water pump to operate according to the target start-stop ratio when the real-time temperature is less than the first preset temperature and the real-time temperature is greater than or equal to the second preset temperature.

[0059] (1) When the real-time temperature is less than the first preset temperature and the real-time temperature is greater than or equal to the second preset temperature, the start-stop temperature range corresponding to the real-time temperature is determined.

[0060] (2) The preset start-stop ratio corresponding to the start-stop temperature range is used as the target start-stop ratio.

[0061] (3) Control the water pump to operate according to the target start-stop ratio.

[0062] As an example, the first preset temperature is set to 30°C and the second preset temperature is set to 10°C. The temperature interval [10, 30) between the first preset temperature and the second preset temperature is subdivided. For example, the temperature interval [10, 30) can be subdivided into multiple start and stop temperature intervals [10, 15), [15, 20), [20, 25), and [25, 30).

[0063] Among them, the target start-stop ratio corresponding to the start-stop temperature range [25, 30) can be 1 / 5, for example, the water pump starts for 1 minute and stops for 5 minutes; the target start-stop ratio corresponding to the start-stop temperature range [20, 25) can be 1 / 4, for example, the water pump starts for 1 minute and stops for 4 minutes; the target start-stop ratio corresponding to the start-stop temperature range [15, 20) can be 1 / 3, for example, the water pump starts for 1 minute and stops for 3 minutes; the target start-stop ratio corresponding to the start-stop temperature range [10, 15) can be 1 / 2, for example, the water pump starts for 1 minute and stops for 2 minutes, then:

[0064] When the real-time temperature is 28°C, it is determined that the real-time temperature belongs to the start-stop temperature range [25, 30), and the corresponding target start-stop ratio is 1 / 5. The controller controls the water pump to work according to the time of starting for 1 minute and stopping for 5 minutes.

[0065] When the real-time temperature is 23°C, it is determined that the real-time temperature belongs to the start-stop temperature range [20, 25), and the corresponding target start-stop ratio is 1 / 4. The controller controls the water pump to work according to the time of starting for 1 minute and stopping for 4 minutes.

[0066] When the real-time temperature is 17°C, it is determined that the real-time temperature belongs to the start-stop temperature range [15, 20), and the corresponding target start-stop ratio is 1 / 3. The controller controls the water pump to work according to the time of starting for 1 minute and stopping for 3 minutes.

[0067] When the real-time temperature is 12°C, it is determined that the real-time temperature belongs to the start-stop temperature range [10, 15), and the corresponding target start-stop ratio is 1 / 2. The controller controls the water pump to work according to the time of starting for 1 minute and stopping for 2 minutes.

[0068] It should be noted that the values of temperature, start-stop ratio, and start-stop time in the above examples are only used as an example to facilitate understanding.

[0069] In some embodiments, the lower the temperature in the start-stop temperature range where the real-time temperature is located, the higher the corresponding preset start-stop ratio.

[0070] Specifically, if the temperature in the start-stop temperature range where the real-time temperature is located is lower, the proportion of the water pump startup time in each start-stop cycle time is higher, and the proportion of the water pump shutdown time in each start-stop cycle time is shorter.

[0071] In some embodiments, the first preset temperature is set to T1, the second preset temperature is set to T2, and the temperature interval [T2, T1) is subdivided into different start-stop temperature intervals according to the temperature difference a, where:

[0072] When T1>Tx≥T1-a, the pump start-stop ratio is a / (T1-T2);

[0073] When T1-a>Tx≥T1-2a, the pump start-stop ratio is 2a / (T1-T2);

[0074] When T1-2a>Tx≥T1-3a, the water pump start-stop ratio is 3a / (T1-T2); ...

[0076] Until T2+2>Tx≥T2, the water pump start-stop ratio is 1.

[0077] As an example, assume T1 = 30°C, T2 = 10°C, and a = 2°C. Then:

[0078] When 30>Tx≥28, the pump start-stop ratio is 2 / (T1-T2)=2 / (30-10)=1 / 10;

[0079] When 28>Tx≥26, the pump start-stop ratio is 4 / (T1-T2)=4 / (30-10)=2 / 10;

[0080] When 26>Tx≥24, the pump start-stop ratio is 6 / (T1-T2)=6 / (30-10)=3 / 10; ...

[0082] Until 12>Tx≥10, the pump start-stop ratio is 1.

[0083] It should be noted that the calculated start-stop ratio is only the ratio of the pump's start time to its stop time, not the specific start and stop times. The pump's start and stop times can be set based on this ratio. Furthermore, the values for the first preset temperature T1, the second preset temperature T2, and the temperature difference a in the above example are provided as examples for ease of understanding.

[0084] In some embodiments, the anti-icing blockage control method provided by the embodiments of the present invention may further include the following steps.

[0085] (1) When the real-time temperature is greater than or equal to the first preset temperature, the water pump is controlled to stop working.

[0086] (2) When the real-time temperature is lower than the second preset temperature and the real-time temperature is higher than or equal to the third preset temperature, the water pump is controlled to start working.

[0087] (3) When the real-time temperature is lower than the third preset temperature and is higher than or equal to the fourth preset temperature of the refrigeration system, the water pump is controlled to operate according to the ice making start-stop ratio.

[0088] The fourth preset temperature is lower than the third preset temperature, and the fourth preset temperature is a shutdown temperature of the refrigeration system. That is, when the real-time temperature is lower than the fourth preset temperature, the refrigeration system stops refrigeration.

[0089] In some embodiments, the fourth preset temperature can be preset according to actual needs.

[0090] In some embodiments, the ice making start-stop ratio can be preset according to actual needs.

[0091] As an example, the first preset temperature is set to 30°C, the second preset temperature is set to 10°C, the third preset temperature is set to 1°C, and the fourth preset temperature is set to -2.5°C. Then:

[0092] When the real-time temperature is greater than or equal to 30°C, the refrigeration system controls the water pump to stop working.

[0093] When the real-time temperature is in the temperature range [1, 10), the refrigeration system controls the water pump to keep in working state.

[0094] When the real-time temperature is within the temperature range [-2.5, 1), the refrigeration system operates according to the ice-making start-stop ratio. For example, when the real-time temperature is within the temperature range [-2.5, 1), the ice-making start-stop ratio can be 1 / 2, with the water pump running for 1 minute and then stopping for 2 minutes. Specifically, when the real-time temperature is -2°C, the water pump operates for 1 minute and then stops for 2 minutes; when the real-time temperature is 0.5°C, the water pump operates for 1 minute and then stops for 2 minutes.

[0095] It should be noted that the values of temperature, start-stop ratio, and start-stop time in the above examples are only used as an example to facilitate understanding.

[0096] In some embodiments, the anti-icing blockage control method provided by the embodiments of the present invention may further include the following steps.

[0097] (1) When a cooling instruction is received, the real-time temperature of the cooling medium is obtained as the starting temperature.

[0098] (2) If the starting temperature is greater than the third preset temperature, the refrigeration module is started to perform refrigeration.

[0099] (3) If the starting temperature is lower than the third preset temperature, the real-time temperature of the cooling medium is continuously detected until the real-time temperature of the cooling medium is higher than the third preset temperature, and then the refrigeration module is started for refrigeration.

[0100] As an example, the third preset temperature is set to 1°C. The temperature detector detects the real-time temperature of the cooling medium and uses this real-time temperature as the startup temperature. For example, when the temperature detector detects that the real-time temperature of the cooling medium is 2°C, the refrigeration module is activated for cooling, and the compressor and evaporator begin to operate. When the temperature detector detects that the real-time temperature of the cooling medium is 0°C, the refrigeration module is not activated. The temperature detector continues to detect the real-time temperature of the cooling medium until the temperature detector detects that the real-time temperature of the cooling medium is greater than 1°C, at which point the refrigeration module is activated for cooling.

[0101] In some implementations, the cooling instruction may be generated based on user input.

[0102] For example, the refrigeration system may be provided with a touch screen display, which may display functions such as refrigeration options. A user may trigger and generate a refrigeration instruction by touching the refrigeration option.

[0103] In addition to receiving user input via a touch screen display, the refrigeration system can also receive user input via buttons. For example, a sparkling water machine can be provided with a refrigeration button, which the user can trigger and generate a refrigeration command by pressing the refrigeration button.

[0104] The refrigeration system may also be provided with a communication module, which may be connected to the user's terminal for communication so that the user may trigger and generate a refrigeration instruction through an application software associated with the bubble water machine.

[0105] In some embodiments, the anti-icing control method provided by the embodiment of the present invention may further include the steps of:

[0106] If the real-time temperature of the cooling medium is lower than the fourth preset temperature, the refrigeration module is controlled to stop working.

[0107] As an example, the fourth preset temperature is set to -2.5°C. When the temperature detector detects that the real-time temperature of the cooling medium is less than -2.5°C, the refrigeration system controls the refrigeration module to stop operating. For example, when the real-time temperature is -2.6°C or -3°C, the refrigeration system controls the refrigeration module to stop operating. This can improve the situation where the evaporator continues to cool when the cooling medium temperature is low, causing the temperature around the heat exchange tube to continue to drop, leading to ice blockage of the heat exchange tube.

[0108] In some embodiments, the steps in step 220 control the water pump to operate according to the target start-stop ratio, which may include the steps of: controlling the water pump to operate according to the target start-stop ratio, and controlling the start time of the water pump to be greater than or equal to the first preset duration, and the stop time of the water pump to be less than or equal to the second preset duration; the first preset duration is less than the second preset duration.

[0109] The first preset duration and the second preset duration can be preset according to needs.

[0110] Specifically, when the real-time temperature is lower than the first preset temperature and higher than or equal to the second preset temperature, the controller controls the water pump to start for a time longer than or equal to the first preset duration and to stop for a time shorter than or equal to the second preset duration.

[0111] As an example, the first preset temperature is set to 30° C., the second preset temperature is set to 10° C., the first preset time is set to 5 seconds, and the second preset time is set to 10 minutes.

[0112] When the real-time temperature is in the temperature range [10, 30), the water pump start time should be greater than 5 seconds, for example, the water pump start time is 5 seconds, 10 seconds, 40 seconds, 70 seconds, etc. The water pump down time should be less than or equal to 10 minutes, for example, the water pump positioning down time is 10 minutes, 7 minutes, 6 minutes, 4 minutes, etc.

[0113] Please refer to Figure 3 An embodiment of the present invention further provides an anti-icing and blocking control device for use in a refrigeration system.

[0115] The determination module is used to control the water pump to operate according to the target start-stop ratio when the real-time temperature is lower than the first preset temperature and the real-time temperature is greater than or equal to the second preset temperature.

[0116] Among them, the first preset temperature is greater than the second preset temperature; the second preset temperature is greater than the third preset temperature of the refrigeration system; the first preset temperature is the load critical temperature of the refrigeration system; and the third preset temperature is the ice-making layer temperature of the refrigeration system.

[0117] In some embodiments, the second determination module 330 is specifically used to: when the real-time temperature is less than the first preset temperature and the real-time temperature is greater than or equal to the second preset temperature, determine the start-stop temperature range corresponding to the real-time temperature; use the preset start-stop ratio corresponding to the start-stop temperature range as the target start-stop ratio; and control the water pump to work according to the target start-stop ratio.
