[0035] The present invention will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0036] It should be noted that the term "comprises" or any other variation thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In addition, the terms "first", "second", etc. are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0037] In one embodiment of the present application, a method for controlling humidity in a storage room is provided, wherein the storage room in the method may be a freezer or a refrigeration room in a freezer, a refrigerator or a wine cabinet, and the storage room may also be a refrigeration compartment in a transport refrigeration vehicle, etc. The humidity control method provided in the embodiment of the present application is applied to a storage space where items that need to be stored at a constant humidity are located, or to a means of transport that needs to be stored at a constant humidity during transportation.

[0038] Please refer to Figure 1 , is a flow chart of a humidity control method for a storage compartment provided in an embodiment of the present application, the method being executed by a humidity control system, and the method comprising the following steps:

[0039] Step S1: Obtain the internal humidity value of the storage room.

[0040] Optionally, a humidity sensor is provided inside the storage room, and the humidity control system obtains the internal humidity value through the humidity sensor.

[0041] Step S2: When the internal humidity value is not within the first humidity interval, obtaining the internal temperature value.

[0042] The first humidity range may be a preset default humidity range, which is suitable for most storage situations, or the first humidity range may be a humidity range set by the user based on the items stored in the storage room.

[0043] Step S3: When the internal temperature value is not within the first temperature range, adjusting the internal temperature value to the second temperature range.

[0044] The second temperature interval is a subset of the first temperature interval. The first temperature interval is a constant temperature floating range to be maintained in the storage room. Since the solution provided in the embodiment of the present application requires adjustment of the internal humidity of the storage room after adjusting the temperature, the humidity adjustment process may have a certain impact on the temperature. Therefore, it is necessary to first adjust the internal temperature value to a second temperature interval with a smaller range, and then adjust the humidity, so as to avoid the internal temperature value after the humidity adjustment not being within the first temperature interval.

[0045] Optionally, the temperature value in the first temperature interval is T1, and the compressor off point of the current cooling gear is ≤T1≤the compressor on point of the current cooling gear. Then the temperature value T2 in the second temperature interval may be: the compressor off point of the current cooling gear + 0.5℃ ≤T2≤the compressor on point of the current gear-0.5℃. In different environments, the cooling gears set by the user are different, and the corresponding compressor off point and compressor on point are different.

[0046] Step S4: When the internal temperature value reaches the second temperature range, the internal humidity value is adjusted to the first humidity range.

[0047] When the internal temperature reaches the second temperature interval, that is, the internal temperature T t Satisfy: The compressor shutdown point of the current cooling gear + 0.5℃ ≤ T t ≤The compressor start point of the current cooling gear is -0.5℃.

[0048] In summary, in the embodiment of the present application, when it is necessary to adjust the air humidity in the storage room, the internal temperature of the storage room is first obtained, and the internal temperature value is adjusted according to the relationship between the obtained internal temperature value and the first temperature range, and when the internal temperature value is adjusted to the second temperature range, the internal humidity value is adjusted. Compared with directly adjusting the humidity without considering the temperature, the solution provided by the present application can avoid the fluctuation of the internal humidity value caused by the subsequent temperature adjustment, and the embodiment of the present application avoids indirectly controlling the internal humidity value by controlling the temperature value, which is conducive to accurate humidity control of the storage room and realizes constant humidity control of the storage room.

[0049] In the solution provided in the embodiment of the present application, after the internal humidity value is obtained, when it is determined that the internal humidity value is not in the first humidity interval, the humidity value needs to be adjusted. Therefore, depending on the humidity value, there may be three situations, namely, the internal humidity value is in the first humidity interval, the internal humidity value is higher than the first humidity interval, and the internal humidity value is lower than the first humidity interval.

[0050] The following will describe the manner in which the humidity control system performs humidity control when the internal humidity value is within different ranges through an illustrative embodiment.

[0051] Case 1: The internal humidity value is lower than the first humidity range

[0052] When the internal humidity value obtained is lower than the first humidity range, the humidity control system obtains the internal temperature value. The obtained internal temperature value may be in the following three situations:

[0053] 1. The internal temperature value is lower than the first temperature range

[0054] If the internal humidity value is lower than the first humidity range and the internal temperature value is lower than the first temperature range, the humidity control system first starts the heating unit, and the temperature inside the storage room rises. After the temperature of the storage room rises to the second temperature range, heating is no longer required and the heating unit is turned off.

[0055] Optionally, the heating unit includes a heating wire and an evaporation fan. When the heating unit is turned on, the heating wire is turned on for heating, and the evaporation fan is turned on to send heated air into the storage room, thereby increasing the temperature inside the storage room. When the heating unit is turned off, the heating wire is controlled to stop heating.

[0056] Optionally, when the heating unit is heating, the heating power of the heating wire is negatively correlated with the internal temperature value, and the rotation speed of the evaporating fan is negatively correlated with the internal temperature value.

[0057] For example, when the heating unit is started, the current internal temperature value T t ≤The compressor shutdown point of the current cooling gear - T, then the heating wire is turned on with power B t =10%+10N, the speed of the evaporating fan is Z t =35%+5N, where T is an integer from 0 to 9. Then T t The lower it is, the larger the corresponding N value is, the greater the current heating wire start-up rate is, and the faster the evaporating fan speed is.

[0058] At this time, if the internal temperature value of the storage compartment is within the second temperature range, the humidity control system starts the humidification unit, and the internal humidity value of the storage compartment increases. When the internal humidity value reaches the second humidity range, the humidification unit is turned off.

[0059] The second humidity interval is a subset of the first humidity interval. For example, if the first humidity interval is 60%-70%, the second humidity interval is 60%-65%. During the humidification process, the internal humidity value of the storage compartment is periodically detected, and the humidification can be stopped as long as the internal humidity value meets the lower humidity in the first humidity interval.

[0060] 2. The internal temperature value is higher than the first temperature range

[0061] When the internal humidity value is lower than the first humidity interval and the internal temperature value is higher than the first temperature interval, the storage room should be cooled first and then humidified.

[0062] The humidity control system first starts the cooling unit, and the temperature inside the storage room decreases. After the temperature of the storage room decreases to the second temperature range, no further cooling is required, and the cooling unit is turned off.

[0063] Optionally, the cooling unit includes a compressor, an evaporator fan and an evaporator. The evaporator fan sends water vapor generated by the evaporator to the vicinity of the compressor. The compressor is used for refrigeration to reduce the air temperature, and the cold air is sent into the storage room through the evaporator fan, thereby reducing the internal temperature of the storage room.

[0064] Optionally, when cooling is performed, the rotation speed of the compressor is positively correlated with the current internal temperature value, and the rotation speed of the evaporating fan is positively correlated with the current internal temperature value.

[0065] For example, after starting the cooling unit, at the internal temperature value T t ≥The compressor start point of the current gear + N, the compressor speed Comp t =(45%+5N)×30, evaporator fan speed Z t =35%+5N, wherein N is an integer from 1 to 13.

[0066] At this time, if the internal temperature value of the storage compartment is within the second temperature range, the humidity control system starts the humidification unit to increase the internal humidity of the storage compartment, and turns off the humidification unit when the internal humidity value reaches the second humidity range.

[0067] In a possible embodiment, the humidification unit includes a humidification fan and an evaporator. The humidification fan is used to deliver water vapor generated by the evaporator into the storage compartment through the air duct and the damper. When the humidity control system controls the humidification unit to start, the speed of the humidification fan is negatively correlated with the internal humidity value, that is, the lower the current internal humidity value, the larger the humidity range that needs to be adjusted. At this time, the speed of the humidification fan is controlled to be higher. When the internal humidity value is higher, that is, the internal humidity value is closer to the second humidity range, the speed of the humidification fan is controlled to be lower.

[0068] For example, the humidification fan speed J t =35%+10X, and the current internal humidity value RH t ≤65%-5X, where X is an integer of 0-6. The lower the humidity value, the larger X is, and the faster the humidification fan speed is.

[0069] 3. The internal temperature value is in the first temperature range

[0070] When the internal temperature value has met the temperature requirement of the current cooling gear, there is no need to adjust the temperature, and the internal humidity of the storage compartment can be adjusted directly. When the internal humidity value is not within the first humidity range and the internal temperature value is within the first temperature range, the internal humidity value is adjusted to the first humidity range.

[0071] Optionally, when the internal humidity value is lower than the first humidity interval and the internal temperature value is within the first temperature interval, the humidification unit is started, and when it is detected that the internal humidity value reaches the second humidity interval, the humidification unit is turned off.

[0072] Case 2: The internal humidity value is higher than the first humidity range

[0073] When the internal humidity value is high, it is necessary to first obtain the internal temperature value of the storage room, and after adjusting the internal temperature, increase the humidity value in the storage room.

[0074] When the internal humidity value is high, there may be three situations for obtaining the internal temperature value of the storage room, namely, the internal temperature value is higher than the first temperature interval, the internal temperature value is lower than the first temperature interval, and the first temperature value is within the first temperature interval. If the internal temperature value is in the above three different situations, the specific implementation of the humidity control system adjusting the internal temperature value can refer to the relevant content of controlling the heating unit and the cooling unit described in the above situation 1, and this embodiment will not be repeated here.

[0075] When the internal humidity value is higher than the first humidity interval, the internal temperature value is first controlled to reach the second temperature interval, and when the internal temperature value reaches the second temperature interval, the dehumidification unit is started. Subsequently, after the internal humidity value decreases to the third humidity interval, the dehumidification unit is turned off.

[0076] The third humidity interval is a subset of the first humidity interval, and the humidity value of the third humidity interval is greater than or equal to the humidity value of the second humidity interval. Since dehumidification is required when the humidity is high, dehumidification can be stopped when it is detected that the internal humidity value has reached a higher humidity level in the first humidity interval. Therefore, the humidity value of the third humidity interval is higher than the humidity value in the second humidity interval referenced during the humidification process, or is equal to the humidity value in the second humidity interval. For example, the first humidity interval is 60%-70%, the second humidity interval is 60%-65%, and the third temperature interval is 65%-70%.

[0077] In a possible embodiment, the dehumidification unit includes a water absorption component, a dehumidification damper and a dehumidification fan. The water absorption component can absorb water vapor in the air, and the dehumidification fan can send relatively dry air into the storage compartment through the air duct and the dehumidification damper, thereby achieving the purpose of dehumidification.

[0078] In the above process, when the internal humidity value of the current storage room is high, the dehumidification fan speed is required to be higher and the opening angle of the dehumidification damper is required to be larger. That is, when the dehumidification unit is started, the speed of the dehumidification fan is positively correlated with the internal humidity value, and the opening angle of the dehumidification damper is positively correlated with the internal humidity value.

[0079] In another possible implementation, the dehumidification unit includes a compressor, an evaporative fan and a dehumidification damper. The compressor is used for cooling to reduce the ambient air temperature, and the dehumidification fan is used to send cold air into the storage room through the dehumidification damper to reduce the air temperature inside the storage room. At this time, the saturation of water vapor in the air inside the storage room is reduced, thereby achieving the purpose of dehumidification.

[0080] In the above process, the speed of the compressor is positively correlated with the internal humidity value, the speed of the dehumidification fan is positively correlated with the internal humidity value, and the opening angle of the dehumidification damper is positively correlated with the internal humidity value. For example, the third humidity threshold is 65%-70%. t ≥65%+5X, the current dehumidification damper opening angle CS t =0+15X, compressor speed Comp t =(45%+5X)×30, evaporator fan speed Z t =35%+5X. Then the internal humidity value is RH t The larger the value, the larger the X value, and the larger the dehumidification damper opening angle CS t The larger the compressor speed Comp t The larger the evaporation fan speed Z t The bigger.

[0081] Optionally, in the scheme of adjusting humidity based on compressor cooling, since the internal temperature may be reduced while the humidity is reduced, in order to avoid large fluctuations in the temperature of the storage room, when the dehumidification unit is started and the internal humidity value reaches the second humidity interval, the heating unit is started. And when the heating unit is started and the internal temperature value reaches the second temperature interval, or the internal humidity value reaches the third humidity interval, the heating unit is turned off.

[0082] Among them, when the internal humidity value reaches the second humidity interval, it indicates that the current internal humidity value has decreased significantly, and the internal temperature value has also decreased significantly at this time. Therefore, the heating unit is started to increase the temperature inside the storage room. When the temperature inside the storage room rises to the second temperature interval, it indicates that the current internal temperature value meets the temperature requirements of the storage room storage, and the heating unit is turned off. In addition, since the increase in the temperature inside the storage room may cause the internal humidity to rise, and some items have stronger requirements for storage humidity, in order to ensure that the internal humidity of the current storage room meets the storage requirements as much as possible, the heating unit is turned off when it is detected that the internal humidity reaches the third humidity interval. It can still ensure the constant temperature as much as possible under the condition of meeting the humidity requirements, and avoid large fluctuations in the internal temperature value of the storage room.

[0083] Case 3: The internal humidity value is within the first humidity range

[0084] When the internal humidity value is within the first humidity range, the humidity control system does not need to humidify or dehumidify. It is necessary to turn on the spoiler unit to allow air to circulate inside the storage room and keep the internal air uniform, which is conducive to improving the accuracy of humidity measurement.

[0085] Optionally, the spoiler unit includes a spoiler fan. When the spoiler unit is started, the spoiler fan is started, and the rotation speed of the spoiler fan is negatively correlated with the internal humidity value. For example, the first humidity interval is 60%-70%. t When ≤70%+5X, the speed of the turbulent fan is T t =55%+X, wherein X is an integer from 0 to 10.

[0086] Please refer to Figure 2 , which shows a flow chart of a humidity control method provided by an exemplary embodiment of the present application. First, the internal humidity value of the storage compartment is obtained, and it is determined whether the internal humidity value is within a first humidity interval. When the internal humidity value is within the first humidity interval, the turbulent fan is started.

[0087] When the internal humidity value is higher than the first humidity interval, the internal temperature value is obtained, and it is determined whether the internal temperature value is in the first temperature interval. When the internal temperature value is in the first temperature interval, the dehumidification unit is started; when the internal temperature value is higher than the first temperature interval, the cooling unit is started, and then it is determined whether the internal temperature is reduced to the second temperature interval. When it is reduced to the second temperature interval, the cooling unit is turned off and the dehumidification unit is started. When it is not reduced to the second temperature interval, it is re-determined whether the internal temperature is reduced to the second temperature interval; when the internal temperature value is lower than the first temperature interval, the heating unit is started, and then it is determined whether the internal temperature is increased to the second temperature interval. When it is increased to the second temperature interval, the heating unit is turned off and the dehumidification unit is started. When it is not increased to the second temperature interval, it is re-determined whether the internal temperature is increased to the second temperature interval. And, when the internal humidity value is reduced to the third humidity interval, the dehumidification unit is turned off.

[0088] When the internal humidity value is lower than the first humidity interval, the internal temperature value is obtained to determine whether the internal temperature value is within the first temperature interval. When the internal temperature value is within the first temperature interval, the humidification unit is started; when the internal temperature value is higher than the first temperature interval, the cooling unit is started, and then it is determined whether the internal temperature is reduced to the second temperature interval. When it is reduced to the second temperature interval, the cooling unit is turned off and the humidification unit is started. If it has not been reduced to the second temperature interval, it is re-determined whether the internal temperature is reduced to the second temperature interval; when the internal temperature value is lower than the first temperature interval, the heating unit is started, and then it is determined whether the internal temperature rises to the second temperature interval. When it rises to the second temperature interval, the heating unit is turned off and the humidification unit is started. If it has not been increased to the second temperature interval, it is re-determined whether the internal temperature rises to the second temperature interval. In addition, when the internal humidity value reaches the second humidity interval, the humidification unit is turned off.

[0089] In summary, the solution provided by the embodiment of the present application can achieve constant humidity control of the storage room by first controlling the temperature and then controlling the humidification unit or the dehumidification unit when different internal humidity values ​​are detected. And at different internal temperature values, by controlling the heating unit and the cooling unit, combined with humidity control, more accurate humidity control can be achieved. In addition, in the solution of using compressor refrigeration to reduce humidity, after the humidity is adjusted, temperature compensation is achieved by starting the heating unit, which can control the temperature as constant as possible while ensuring constant humidity, avoiding large temperature fluctuations during the dehumidification process.

[0090] In one embodiment of the present invention, a storage cabinet is further provided, the storage cabinet comprising a humidity control system and a storage compartment, wherein the humidity control system is used to execute the steps in a humidity control method for a storage compartment as shown in any one of the above embodiments.

The humidity adjustment module 430 includes a dehumidification unit 431, a humidification unit 432, and a spoiler unit 433.

[0094] The humidity control system 410 is connected to the temperature adjustment module 420 and the humidity adjustment module 430 respectively. After receiving the internal humidity value sent by the humidity sensing module 450, if the internal temperature value is not within the first temperature interval, the internal temperature value of the storage room is obtained based on the temperature sensing module 440. When the humidity control system 410 determines that the internal temperature value is lower than the first temperature interval, the heating unit 421 is controlled to start and heat. When the humidity control system 410 determines that the internal temperature value is higher than the first temperature interval, the cooling unit 422 is controlled to start and cool. When the internal temperature value obtained reaches the second temperature interval and the internal humidity value obtained is higher than the first humidity interval, the dehumidification unit 431 is controlled to start and reduce the internal humidity. When the internal temperature value obtained reaches the second temperature interval and the internal humidity value obtained is lower than the first humidity interval, the humidity control system controls the humidification unit 432 to start and increase the internal humidity. In addition, when the internal humidity value obtained is within the first humidity interval, the spoiler unit 433 is controlled to start.
