[0036] Figure 1 Schematic diagram of the implementation environment of the embodiment of the present disclosure. Figure 1As shown, the implementation environment can include a refrigeration device 1. The refrigeration device 1 can be a refrigerator, a maturation cabinet, etc. of a single refrigeration system. Specifically, the refrigeration device 1 of the embodiment of the present disclosure is a maturation cabinet. The refrigeration device 1 includes a refrigeration compartment, a compressor 20, an electronic expansion valve 30, and an electronic control device. The refrigeration compartment 10 is used to store items; the compressor 20 is used to realize the refrigeration of the refrigeration compartment 10. The electronic expansion valve 30 is used to control the flow of refrigerant of the refrigeration device 1. The electronic control device includes a processor, which is used to control the compressor 20 and the electronic expansion valve 30 to realize various functions of the refrigeration device 1.

[0037] Optionally, the refrigeration device 1 further includes a first heat exchanger 40, a second heat exchanger 50, and a capillary tube 60. The first heat exchanger 40, the compressor 20, the second heat exchanger 50, the electronic expansion valve 30, and the capillary tube 60 are connected in sequence to jointly constitute a refrigeration system of the refrigeration device 1 to realize the refrigeration function of the refrigeration device 1.

[0038] In combination with the refrigeration device, Figure 1 As shown, the refrigeration device, the embodiment of the present disclosure provides a method for controlling the refrigeration device, and the execution subject of the method can be a processor. As shown, Figure 2 The method includes:

[0039] S201, the processor determines a refrigeration cycle period of the compressor.

[0040] S202, the processor obtains an average integrated humidity value of the refrigeration compartment in the refrigeration cycle period.

[0041] It should be noted that the temperature of the refrigeration compartment is low, and the refrigeration of the compressor is used to maintain the refrigeration compartment at a lower temperature, for example, the temperature of the refrigeration compartment is 0℃. In this way, low-temperature storage of the refrigeration compartment can be realized, and the constant-temperature refrigeration effect of the refrigeration compartment can be ensured.

[0042] S203, the processor controls the opening degree of the electronic expansion valve according to the average integrated humidity value of the refrigeration cycle period and a target humidity value.

[0043] The target humidity value refers to the expected operating humidity of the refrigeration compartment. The target humidity value is a higher humidity value. Exemplarily, the value range of the target humidity value is [75%, 90%]. Specifically, the target humidity value can be set to 75%, 80%, or 90%. More specifically, the target humidity value is set to 80%.

[0044] The method for controlling the refrigeration equipment provided in the embodiments of the present disclosure can make the temperature of the refrigeration chamber reach a stable low-temperature state through the operation of the compressor in the refrigeration cycle period, and can more accurately reflect the cumulative state of the humidity of the refrigeration chamber at the time of the operation of the compressor rather than the humidity value of a single instantaneous point, so as to better reflect the actual change trend of the humidity of the refrigeration chamber. In this case, the opening of the electronic expansion valve can be controlled through the average integrated humidity value and the target humidity value, so as to accurately maintain the humidity in a high-humidity state under the low-temperature condition and improve the precision and stability of the constant-temperature and constant-humidity control.

[0045] Optionally, determining the refrigeration cycle period of the compressor comprises: obtaining a plurality of continuous refrigeration periods of the compressor; and determining the plurality of continuous refrigeration periods as the refrigeration cycle period of the compressor.

[0046] The refrigeration period of the compressor refers to that the compressor is started after obtaining a compressor start signal, the compressor is stopped after obtaining a compressor stop signal, and the compressor is started again after obtaining a compressor start signal again, wherein the compressor is started to the next time of being started, that is, one refrigeration period of the compressor.

[0047] In the embodiments of the present disclosure, since the working state of the compressor is affected by various factors such as load change, environmental temperature change, state change of the refrigerant, etc., by determining the plurality of continuous refrigeration periods as the refrigeration cycle period of the compressor, the influence of atypical or temporary fluctuations can be eliminated, and a more stable and real average integrated humidity value can be obtained.

[0048] Optionally, the refrigeration cycle period comprises a plurality of continuous refrigeration periods, and the average integrated humidity value of the refrigeration chamber in the refrigeration cycle period comprises: collecting a humidity parameter in each refrigeration period every interval of a preset time length; determining an integrated humidity value of each refrigeration period according to the humidity parameter in each refrigeration period, to obtain a plurality of integrated humidity values of the plurality of refrigeration periods; calculating an average value of the plurality of integrated humidity values; and determining the average value of the plurality of integrated humidity values as the average integrated humidity value of the refrigeration chamber in the refrigeration cycle period.

[0049] Exemplarily, the preset time length can be in a range of [5 seconds, 15 seconds]. Specifically, the preset time length can be set to 5 seconds, 10 seconds or 15 seconds. More specifically, the preset time length is set to 10 seconds.

[0050] For example, the humidity parameters collected in the first cooling cycle can be expressed as: rh11 (the first humidity parameter of the first cooling cycle), rh12 (the second humidity parameter of the first cooling cycle), rh13 (the third humidity parameter of the first cooling cycle), ..., rh1n (the nth humidity parameter of the first cooling cycle, n represents the last humidity parameter collected in the first cooling cycle), then the integrated humidity value RH1n of the first cooling cycle = (rh11 + rh12 + rh13 + ... + rh1n) / n; the humidity parameter of the second cooling cycle is The numbers can be expressed as: rh21 (the first humidity parameter of the second refrigeration cycle), rh22 (the second humidity parameter of the second refrigeration cycle), rh23 (the third humidity parameter of the second refrigeration cycle), ..., rh2m (the mth humidity parameter of the second refrigeration cycle, where m represents the last humidity parameter collected in the second refrigeration cycle), then the integrated humidity value RH2m of the first refrigeration cycle = (rh21+rh22+rh23+...+rh2m) / m; according to the above method, multiple integrated humidity values ​​of multiple refrigeration cycles can be obtained.

[0051] In this disclosed embodiment, by collecting humidity parameters within each refrigeration cycle at preset intervals, the changes in humidity in the refrigeration room can be monitored in real time, achieving real-time feedback and rapid response. By determining multiple integrated humidity values ​​for multiple refrigeration cycles, the overall change trend of humidity within multiple refrigeration cycles can be better reflected, without being affected by short-term fluctuations. By calculating the average value of the integrated humidity values ​​for multiple refrigeration cycles, accidental fluctuations are eliminated, and the typical humidity level of the refrigeration room within a certain time span (i.e., the refrigeration cycle) is obtained. This average integrated humidity value is more representative and can represent the actual humidity, thereby accurately adjusting the opening of the electronic expansion valve, and is also more conducive to stable humidity control, achieving continuous, dynamic and precise control of humidity.

[0052] Optionally, controlling the opening of the electronic expansion valve based on the average integrated humidity value and the target humidity value during the refrigeration cycle includes calculating the absolute value of the difference between the average integrated humidity value and the target humidity value. If the absolute value of the difference is less than or equal to a preset humidity value, controlling the electronic expansion valve to continue operating at the current opening. If the absolute value of the difference is greater than the preset humidity value, obtaining the current opening of the electronic expansion valve for the current refrigeration cycle, and controlling the opening of the electronic expansion valve for the next refrigeration cycle based on the current opening of the electronic expansion valve for the current refrigeration cycle.

[0053] Exemplarily, the preset humidity value ranges from [4%, 6%]. Specifically, the preset humidity value can be set to 4%, 5% or 6%. More specifically, the preset humidity value is set to 5%.

[0054] In the disclosed embodiment, the difference between the actual humidity and the preset humidity value is evaluated in real time by calculating the absolute value of the difference between the average integrated humidity value of the current refrigeration cycle and the target humidity value. When the absolute value of the difference is less than or equal to the preset humidity value, it indicates that the current opening degree setting of the electronic expansion valve has been able to maintain the humidity of the refrigeration compartment within the target humidity range, so there is no need for additional opening degree adjustment, and the current opening degree can be maintained to continue operation, which is beneficial to the stability and energy saving effect of the refrigeration system. When the absolute value of the difference is greater than the preset humidity value, it indicates that there is a large deviation between the actual humidity and the target humidity, and the opening degree of the electronic expansion valve needs to be further adjusted to correct the deviation and achieve on-demand adjustment, so that the humidity of the refrigeration compartment gradually approaches the target humidity. In this way, accurate control of high humidity can be achieved under low temperature conditions, improving the reliability and working efficiency of the entire refrigeration system.

[0055] Optionally, controlling the opening degree of the electronic expansion valve in the next refrigeration cycle according to the current opening degree of the electronic expansion valve in the current refrigeration cycle includes: in the case where the current opening degree of the electronic expansion valve in the current refrigeration cycle is greater than the first preset opening degree, controlling the electronic expansion valve to decrease according to the second preset opening degree in the next refrigeration cycle. In the case where the current opening degree of the electronic expansion valve in the current refrigeration cycle is less than or equal to the first preset opening degree, controlling the electronic expansion valve to continue operating at the current opening degree in the next refrigeration cycle.

[0056] Exemplarily, the first preset opening degree can be in the range of [5%, 7%]. Specifically, the first preset opening degree can be set to 5%, 6%, or 7%. More specifically, the first preset opening degree can be set to 5%.

[0057] Exemplarily, the second preset opening degree can be in the range of [3%, 8%]. Specifically, the second preset opening degree can be set to 3%, 5%, or 8%. More specifically, the second preset opening degree can be set to 5%.

[0058] In the disclosed embodiment, when the current opening degree is greater than the first preset opening degree, since the absolute value of the difference is greater than the preset humidity value at this time, the opening degree of the electronic expansion valve in the next refrigeration cycle is decreased according to the second preset opening degree, so that the evaporation temperature is low, which is beneficial to reducing the humidity, and by gradually reducing the dehumidification speed, over-adjustment can be effectively avoided, so that the target humidity value is gradually approached, and the accuracy of humidity control is improved. When the current opening degree is less than or equal to the first preset opening degree, it indicates that the opening degree of the electronic expansion valve is already small at this time, so the electronic expansion valve is controlled to continue operating at the current opening degree in the next refrigeration cycle to ensure the normal operation of the refrigeration system.

[0059] Optionally, after controlling the electronic expansion valve to continue operating at the current opening degree in the next refrigeration cycle, it further includes: controlling the compressor to continue operating in the current refrigeration cycle; and / or, reducing the operating speed of the compressor.

[0060] It should be noted that the control of the electronic expansion valve to continue running at the current opening in the next refrigeration cycle in the embodiments of the present disclosure means that, in the case that the absolute value of the difference is greater than the preset humidity value, and in the case that the current opening of the electronic expansion valve in the current refrigeration cycle is less than or equal to the first preset opening, the electronic expansion valve is controlled to continue running at the current opening in the next refrigeration cycle.

[0061] Exemplarily, the operating speed of the compressor is reduced until a preset speed. The preset speed represents the lowest speed at which the compressor can operate, which is specifically set according to actual needs.

[0062] In the embodiments of the present disclosure, the opening of the electronic expansion valve has been reduced to a smaller opening, and further reduction will affect the normal operation of the refrigeration system. Therefore, in order to continue to adjust the actual humidity to approach the target humidity value, the compressor is controlled to continue running in the current refrigeration cycle, and / or the operating speed of the compressor is reduced. In this way, the amount of refrigerant circulation and the refrigeration power can be further reduced, and the refrigeration efficiency of the evaporator is reduced, so as to achieve the purpose of controlling humidity.

[0063] The method for controlling the refrigeration equipment is exemplarily described as follows: the initial opening of the electronic expansion valve is preset to be 100%. At this time, if the absolute value of the difference is < 5% of the preset humidity value, the current electronic expansion valve continues to run at the initial opening of 100%, and the difference between the absolute value of the difference and the preset humidity value is continuously judged. If the absolute value of the difference is > 5% at this time, the opening of the electronic expansion valve is reduced by 5% based on the initial opening of 100% in the next refrigeration cycle, i.e. 95%. And continue to judge the difference between the absolute value of the difference and the preset humidity value. If the absolute value of the difference is < 5% at this time, the electronic expansion valve is kept running at the current opening of 95%. If the absolute value of the difference is > 5% at this time, the opening of the electronic expansion valve is reduced by 5% based on the current opening of 95% in the next refrigeration cycle, i.e. 90%. And continue to judge the difference between the absolute value of the difference and the preset humidity value. If the absolute value of the difference is < 5% at this time, the electronic expansion valve is kept running at the current opening of 90%. If the absolute value of the difference is > 5% at this time, the opening of the electronic expansion valve is reduced by 5% based on the current opening of 90% in the next refrigeration cycle, i.e. 85%. …… until the opening of the electronic expansion valve is reduced to 5%.

[0064] Optionally, the method further comprises: obtaining the temperature of the refrigeration chamber. The working state of the compressor is controlled according to the temperature of the refrigeration chamber. The working state of the compressor is used to determine the refrigeration cycle period of the compressor.

[0065] In combination Figure 3 As shown in the figure, the embodiments of the present disclosure provide another method for controlling the refrigeration equipment, comprising:

[0066] S301, the processor obtains the temperature of the refrigeration chamber.

[0067] S302: The processor controls the working state of the compressor according to the temperature of the refrigeration compartment.

[0071] S305: The processor controls the opening of the electronic expansion valve according to the average integrated humidity value of the refrigeration cycle and the target humidity value.

[0072] In this disclosed embodiment, the operating state of the compressor is controlled to maintain the temperature within the refrigeration compartment within the target temperature range, thereby achieving constant temperature control of the refrigeration compartment. The refrigeration cycle can be more accurately determined based on the compressor operating state, thereby precisely stabilizing the humidity in the refrigeration compartment near the set target humidity value. This enables refined and intelligent control of both temperature and humidity in the refrigeration equipment, improving the accuracy and stability of constant temperature and humidity control.

[0073] This control method is applicable to aging cabinets.

[0074] Optionally, controlling the operating state of the compressor according to the temperature of the refrigeration compartment includes: controlling the compressor to turn on when the temperature of the refrigeration compartment is greater than a target temperature, and controlling the compressor to turn off when the temperature of the refrigeration compartment is less than or equal to the target temperature.

[0075] The target temperature represents the desired operating temperature of the refrigeration unit. For example, the target temperature is set based on the user's actual needs. By controlling the operation or shutdown of the compressor, the temperature of the refrigeration compartment is adjusted, ensuring that the temperature of the refrigeration compartment remains stable at the target temperature, achieving a low-temperature constant temperature for the refrigeration unit.

[0076] Optionally, determining the refrigeration cycle of the compressor based on the operating state of the compressor includes: determining the refrigeration cycle of the compressor based on the operating state of the compressor. A plurality of consecutive refrigeration cycles are determined as the refrigeration cycle of the compressor. This makes the determination of the refrigeration cycle more reasonable.
