[0025] In order to make the objectives, features, and advantages of the embodiments of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present application.

[0026] In the description of the present application, it should be understood that the terms "first", "second", etc. are only used for descriptive purposes and cannot be construed as indicating or implying relative importance. In the description of the present application, it should be noted that unless otherwise clearly defined and limited, the terms "comprising" and "having", and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but optionally further includes unlisted steps or units, or optionally further includes other steps or units inherent to these processes, methods, products, or devices. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood in specific cases. In addition, in the description of the present application, unless otherwise stated, "a plurality of" means two or more. "And / or" describes the association relationship of associated objects and indicates that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally represents an "or" relationship between the associated objects before and after.

[0027] In the related art, the computer room air conditioner has relatively high requirements for humidity control. In a computer room with low load or no heat source, the temperature in the computer room can be quickly reduced, and the air treatment is close to isohumid cooling, and the relative humidity will increase. If the humidity is controlled according to the relative humidity, the computer room air conditioner still needs to perform dehumidification operation, but actually at this time, the compressor should be stopped and reheating operation should be carried out. During the above dehumidification process, since the compressor is in a low-frequency operation state, the evaporation temperature is relatively high, higher than the return air dew point temperature, and the dehumidification effect cannot be achieved. Therefore, the control of humidity is unstable, the dehumidification effect is not good, and it is difficult to meet the humidity requirements in the computer room.

[0028] The present application will be described in detail below with reference to specific embodiments.

[0029] In the following method embodiments, for the convenience of description, only the execution subject of each step is introduced as an electrical device.

[0030] Please refer to Figure 1 FIG. for a schematic flow chart of an air conditioner dehumidification control method provided by an embodiment of the present application. As shown in Figure 1As shown in the figure, the method of the embodiment of the present application may include the following steps:

[0031] S101, determine the temperature demand degree and humidity demand degree in the current air conditioner function mode, and execute the air conditioner dehumidification mode based on the temperature demand degree and humidity demand degree.

[0032] It is easy to understand that the current air conditioner function mode may refer to the cooling mode in which the air conditioner device is currently located, or may refer to the cooling mode + dehumidification mode in which the air conditioner device is currently located.

[0033] The temperature demand degree may refer to an index used to determine whether it is necessary to perform a heating operation or a cooling operation on the current indoor ambient temperature relative to the set temperature.

[0034] The humidity demand degree may refer to an index used to determine whether it is necessary to perform a dehumidification operation on the current indoor ambient humidity relative to the set humidity.

[0035] In some embodiments, the calculation method of the temperature demand degree may be: first calculate the ratio between the temperature difference and the temperature proportional band, and then calculate the product of the ratio and 100%, then the temperature demand degree can be obtained; wherein, the temperature difference may be the temperature difference between the actual temperature in the current indoor environment and the set temperature, and the set temperature refers to the temperature value set by the user. The temperature proportional band may refer to a constant set according to experience for adjusting the temperature demand degree. Specifically, if the actual temperature is selected as the actual return air temperature of the air conditioner device, then the set temperature can be the set return air temperature of the air conditioner device. If the actual temperature is selected as the supply air temperature of the air conditioner device, then the set temperature can be the set supply air temperature of the air conditioner device. The actual return air temperature and the actual supply air temperature can be measured by a temperature sensor. The set return air temperature and the set supply air temperature can be determined according to the temperature value set by the user. The set return air temperature may be equal to the temperature value set by the user, or there may be a preset difference between the set return air temperature and the temperature value set by the user. Similarly, the set supply air temperature may be equal to the temperature value set by the user, or there may be a preset difference between the set supply air temperature and the temperature value set by the user.

[0036] The calculation method of the humidity demand degree may be: first calculate the ratio between the moisture content difference and the humidity proportional band, and then calculate the product of the ratio and 100%, then the humidity demand degree can be obtained; wherein, the moisture content difference may be the difference between the actual moisture content in the current indoor environment and the set moisture content, and both the actual moisture content and the set moisture content refer to the absolute moisture content of the air. The set moisture content may be the absolute moisture content corresponding to the temperature value set by the user. The actual moisture content can be measured by a sensor for monitoring air humidity.

[0037] Further, when it is determined that the humidity demand degree is greater than or equal to the humidity demand degree threshold and the temperature demand degree is less than the temperature demand degree threshold, it indicates that the humidity demand of the current environment is relatively large and dehumidification is required. The air conditioner dehumidification mode can be executed, that is, the air conditioner can operate according to the relevant parameters corresponding to the dehumidification mode. Optionally, the humidity demand degree threshold can be set to 100%, and the temperature demand degree threshold can be set to a value less than 100% such as 90% or 86%.

[0038] S102. In the air conditioner dehumidification mode, monitor the return air dew point temperature and the evaporation temperature, and determine the temperature difference between the return air dew point temperature and the evaporation temperature.

[0039] It is easy to understand that the return air dew point temperature can refer to the value calculated based on the indoor return air temperature and the return air relative humidity. The indoor return air temperature is the return air temperature of the internal fan of the air conditioner. The return air relative humidity is the return air relative humidity of the internal fan. The calculation formula of the return air dew point temperature can be the following formula:

[0040]

[0041] where, t d (t, RH) represents the return air dew point temperature, RH represents the return air relative humidity, t represents the indoor return air temperature, the value of m is 17.62, T n The value of is 243.12 °C.

[0042] The evaporation temperature can refer to the saturation temperature at which the refrigerant liquid changes from a liquid to a gas in the evaporator. The evaporation temperature can be derived from the evaporation pressure of the evaporator.

[0043] In some embodiments, in the air conditioner dehumidification mode, the return air dew point temperature and the evaporation temperature can be monitored in real time. Further, the temperature difference between the return air dew point temperature and the evaporation temperature can be calculated in real time.

[0044] S103. If the temperature difference is greater than or equal to the temperature preset value, keep the air conditioner running based on the current air conditioner configuration parameters corresponding to the air conditioner dehumidification mode.

[0045] It is easy to understand that the current air conditioner configuration parameters can include parameters such as the opening degree of the electronic expansion valve and the rotation frequency of the compressor.

[0046] Optionally, the temperature preset value can refer to a value greater than 0, such as a value within the range of 2 - 6.

[0047] In some embodiments, when the temperature difference between the return air dew point temperature and the evaporation temperature is greater than or equal to a temperature preset value, it can indicate that the evaporation temperature is lower than the return air dew point temperature. At this time, the water vapor in the air will adhere to the low-temperature evaporator and condense into dew, which is then discharged outdoors through the water collecting tray and pipeline. Therefore, operating the air conditioner with the current air conditioner configuration parameters corresponding to the dehumidification mode can achieve the dehumidification effect, and then the air conditioner operation can be maintained according to the current air conditioner configuration parameters to maintain the dehumidification effect.

[0048] S104. If the temperature difference is less than the temperature preset value, obtain the target air conditioner adjustment parameter for the current air conditioner configuration parameter, and adjust the air conditioner operation based on the target air conditioner adjustment parameter for the current air conditioner configuration parameter.

[0049] Optionally, the temperature preset value can be set to 0.

[0050] In some embodiments, when the temperature difference between the return air dew point temperature and the evaporation temperature is less than the temperature preset value, it can indicate that the evaporation temperature is higher than the return air dew point temperature. At this time, the water vapor in the air cannot condense into dew when encountering the high temperature of the evaporator, let alone be discharged outdoors. Therefore, operating the air conditioner with the current air conditioner configuration parameters corresponding to the dehumidification mode cannot achieve the dehumidification effect, and then the target air conditioner adjustment parameter for the current air conditioner configuration parameter can be obtained, and the air conditioner operation can be adjusted based on the target air conditioner adjustment parameter for the current air conditioner configuration parameter.

[0051] Among them, the target air conditioner adjustment parameter can include at least one of the electronic expansion valve adjustment parameter and the compressor adjustment parameter. That is, in the embodiments of the present application, the target air conditioner adjustment parameter can be the electronic expansion valve adjustment parameter, the target air conditioner adjustment parameter can be the compressor adjustment parameter, and the target air conditioner adjustment parameter can also include the electronic expansion valve adjustment parameter and the compressor adjustment parameter.

[0052] Optionally, when the target air conditioner adjustment parameter is the electronic expansion valve adjustment parameter, perform the steps of obtaining the target air conditioner adjustment parameter for the current air conditioner configuration parameter and adjusting the air conditioner operation based on the target air conditioner adjustment parameter. Specifically, it can be: obtaining the electronic expansion valve adjustment parameter for the current air conditioner configuration parameter and adjusting the air conditioner operation based on the electronic expansion valve adjustment parameter. Specifically, the electronic expansion valve adjustment parameter can refer to the adjustment step length and adjustment period of the electronic expansion valve. At this time, the adjustment step length can refer to the opening step length of the increased valve, and the adjustment period can refer to the unit time for increasing the opening step length. Obtaining the electronic expansion valve adjustment parameter for the current air conditioner configuration parameter can be understood as obtaining a preset expansion valve adjustment mapping table, searching for the target adjustment step length and target adjustment period corresponding to the air conditioner dehumidification mode in the expansion valve adjustment mapping table, and using the target adjustment step length and target adjustment period as the electronic expansion valve adjustment parameter for the current air conditioner configuration parameter; the preset expansion valve adjustment mapping table can store the mapping relationship between the reference air conditioner operation mode and the adjustment step length and adjustment period of the electronic expansion valve, and the reference air conditioner operation mode can include but is not limited to the air conditioner dehumidification mode, air conditioner refrigeration mode, air conditioner heating mode, etc. Adjusting the air conditioner operation based on the electronic expansion valve adjustment parameter can be understood as increasing the current opening of the electronic expansion valve according to the target adjustment step length and target adjustment period, and operating the air conditioner according to the opening of the adjusted electronic expansion valve. When operating the air conditioner according to the current air conditioner configuration parameter, since the evaporation temperature is higher than the return air dew point temperature, the dehumidification effect cannot be achieved, so it is possible to choose to increase the opening of the electronic expansion valve to increase the liquid supply amount transmitted by the electronic expansion valve, so that the evaporation temperature can be reduced to a temperature value lower than the return air dew point temperature to achieve the dehumidification effect.

[0053] Optionally, when the target air conditioner adjustment parameter is the compressor adjustment parameter, perform the steps of obtaining the target air conditioner adjustment parameter for the current air conditioner configuration parameter and adjusting the air conditioner operation based on the target air conditioner adjustment parameter. Specifically, it can be: obtaining the compressor adjustment parameter for the current air conditioner configuration parameter and adjusting the air conditioner operation based on the compressor adjustment parameter. Specifically, the compressor adjustment parameter can refer to the adjustment step size and adjustment period of the frequency of the compressor. At this time, the adjustment step size can refer to the increased frequency step size, and the adjustment period can refer to the unit time for increasing the frequency step size. Obtaining the compressor adjustment parameter for the current air conditioner configuration parameter can be understood as obtaining a preset compressor adjustment mapping table, searching in the compressor adjustment mapping table for the target frequency adjustment step size and target adjustment period corresponding to the air conditioner dehumidification mode, and taking the target frequency adjustment step size and target adjustment period as the compressor adjustment parameter for the current air conditioner configuration parameter; the preset compressor adjustment mapping table can store the mapping relationship between the reference air conditioner operation mode and the frequency adjustment step size and adjustment period of the compressor, and the reference air conditioner operation mode can include but is not limited to the air conditioner dehumidification mode, the air conditioner refrigeration mode, the air conditioner heating mode, etc. Adjusting the air conditioner operation based on the compressor adjustment parameter can be understood as increasing the current rotation frequency of the compressor according to the target frequency adjustment step size and target adjustment period, and operating the air conditioner according to the adjusted frequency of the compressor. When operating the air conditioner according to the current air conditioner configuration parameter, since the evaporation temperature is higher than the return air dew point temperature, the dehumidification effect cannot be achieved, so the frequency of the compressor can be adjusted upwards to improve the working efficiency of the compressor, increase the refrigeration speed, so that the evaporation temperature can be reduced to a temperature value lower than the return air dew point temperature to achieve the dehumidification effect.

[0054] Optionally, when the target air conditioner adjustment parameters include electronic expansion valve adjustment parameters and compressor adjustment parameters, perform the steps of obtaining the target air conditioner adjustment parameters for the current air conditioner configuration parameters and adjusting the current air conditioner configuration parameters for air conditioner operation based on the target air conditioner adjustment parameters. Specifically, it can be: obtaining the electronic expansion valve adjustment parameters for the current air conditioner configuration parameters, adjusting the electronic expansion valve for air conditioner operation based on the electronic expansion valve adjustment parameters, when it is determined that the evaporation temperature is higher than the return air dew point temperature, obtaining the compressor adjustment parameters for the current air conditioner configuration parameters, stopping adjusting the electronic expansion valve and performing air conditioner operation adjustment based on the compressor adjustment parameters. The interpretations of the electronic expansion valve adjustment parameters and the compressor adjustment parameters can be referred to the descriptions in the above optional embodiments and will not be described here again. That is, the electronic expansion valve adjustment parameters in the target air conditioner adjustment parameters can be preferred for air conditioner operation adjustment, that is, the adjustment step and adjustment period of the electronic expansion valve can be preferred to adjust the opening degree of the electronic expansion valve. If the air conditioner operates according to the adjusted opening degree of the electronic expansion valve and the evaporation temperature is still higher than the return air dew point temperature, at this time, the adjustment step and adjustment period of the compressor frequency can be selected as the first air conditioner adjustment parameter, and the air conditioner operates according to the adjusted compressor. In this way, taking the adjustment step and adjustment period of the compressor frequency as the last adjustment parameter instead of the preferred adjustment parameter can reduce the working duration of the compressor running at high speed and can achieve the effect of energy saving on the basis of achieving the dehumidification effect.

[0055] In the embodiment of the present application, first determine the temperature demand degree and humidity demand degree in the current air conditioner function mode, perform the air conditioner dehumidification mode based on the temperature demand degree and the humidity demand degree. In the air conditioner dehumidification mode, monitor the return air dew point temperature and the evaporation temperature, determine the temperature difference between the return air dew point temperature and the evaporation temperature. When the temperature difference is greater than or equal to the temperature preset value, keep the air conditioner running based on the current air conditioner configuration parameters corresponding to the air conditioner dehumidification mode; when the temperature difference is less than the temperature preset value, obtain the target air conditioner adjustment parameters for the current air conditioner configuration parameters, and adjust the current air conditioner configuration parameters for air conditioner operation based on the target air conditioner adjustment parameters. In the embodiment of the present application, when it is determined that there is a dehumidification demand, by monitoring the magnitude of the difference between the return air dew point temperature and the evaporation temperature, it is possible to adjust the air conditioner operation according to the air conditioner adjustment parameters in the case where the evaporation temperature is higher than the return air dew point temperature and the dehumidification effect cannot be truly achieved, so as to improve the dehumidification effect in the air conditioner dehumidification mode.

[0056] Please refer to Figure 2 , which is a schematic flowchart of an air conditioner dehumidification control method provided by an embodiment of the present application. As Figure 2 shown, the method of the embodiment of the present application may include the following steps:

[0057] S201. Obtain the actual temperature and the target temperature in the current air conditioner function mode, determine the first difference between the actual temperature and the target temperature, and determine the temperature demand degree in the current air conditioner function mode based on the temperature proportional band and the first difference.

[0058] In some embodiments, the actual return air temperature and the target return air temperature in the current air conditioner function mode can be obtained, the actual return air temperature can be determined as the actual temperature, and the target return air temperature can be determined as the target temperature. Among them, the actual return air temperature can refer to the temperature collected by the temperature sensor on the return air side of the air conditioner in the current air conditioner function mode, that is, the temperature of the air inhaled from the inside of the indoor unit. The target return air temperature refers to the return air temperature corresponding to the temperature set by the user in the current air conditioner function mode. The target return air temperature can be equal to the temperature set by the user in the current air conditioner function mode, or the target return air temperature can have a certain difference from the temperature set by the user in the current air conditioner function mode.

[0059] In other embodiments, the actual supply air temperature and the target supply air temperature in the current air conditioner function mode can be obtained, the actual supply air temperature can be determined as the actual temperature, and the target supply air temperature can be determined as the target temperature. Among them, the actual supply air temperature can refer to the temperature collected by the temperature sensor on the supply air side of the air conditioner in the current air conditioner function mode, that is, the temperature of the air discharged from the air outlet of the air conditioner. The target supply air temperature refers to the supply air temperature corresponding to the temperature set by the user in the current air conditioner function mode. The target supply air temperature can be equal to the temperature set by the user in the current air conditioner function mode, or the target supply air temperature can have a certain difference from the temperature set by the user in the current air conditioner function mode.

[0060] Further, the first difference between the actual temperature and the target temperature can be calculated, and the temperature demand degree in the current air conditioner function mode can be determined based on the temperature proportional band and the first difference. The temperature proportional band can refer to a constant set according to experience for adjusting the temperature demand degree. For example, the temperature proportional band can be set to a value such as 1 or 2. The quotient of the first difference and the temperature proportional band can be calculated, and then the product of the quotient and 100% can be calculated to obtain the temperature demand degree.

[0061] S202. Obtain the actual moisture content and the target moisture content in the current air conditioner function mode, determine the second difference between the actual moisture content and the target moisture content, and determine the humidity demand degree in the current function mode based on the humidity proportional band and the second difference.

[0062] It is easy to understand that the actual moisture content refers to the absolute moisture content of the indoor air in the current air conditioner function mode.

[0063] The target moisture content refers to the absolute moisture content of the air corresponding to the temperature set by the user in the current air conditioner function mode.

[0064] The humidity ratio band can refer to a constant set according to experience for adjusting the humidity demand. For example, the temperature ratio band can be set to a value such as 1 or 2.

[0065] In some embodiments, the actual moisture content can be measured by a sensor for monitoring air humidity. The second difference between the actual moisture content and the target moisture content can be calculated, the quotient of the second difference and the humidity ratio band can be calculated, and then the product of the quotient and 100% can be calculated to obtain the humidity demand. The moisture content in the embodiments of the present application is calculated using the absolute moisture content, which can achieve the effect of preventing the air conditioner from entering the dehumidification operation for scenarios where rapid cooling causes high relative humidity and increased dehumidification demand, while the actual absolute moisture content remains basically unchanged and the dehumidification demand should also remain unchanged, and can more effectively control the stability of humidity.

[0066] S203, if the humidity demand is greater than or equal to the humidity demand threshold and the temperature demand is less than the temperature demand threshold, then execute the air conditioner dehumidification mode.

[0067] Optionally, the humidity demand threshold can be set to 100%, and the temperature demand threshold can be set to a value less than 100% such as 90% or 86%.

[0068] In some embodiments, when it is determined that the humidity demand is greater than or equal to the humidity demand threshold and the temperature demand is less than the temperature demand threshold, it indicates that the humidity demand of the current environment is greater, that is, the humidity demand of the current environment is greater relative to the temperature demand, and dehumidification is required. The air conditioner dehumidification mode can be executed, that is, the air conditioner can operate according to the relevant parameters corresponding to the air conditioner dehumidification mode.

[0069] S204, in the air conditioner dehumidification mode, monitor the return air dew point temperature and the evaporation temperature, and determine the temperature difference between the return air dew point temperature and the evaporation temperature.

[0070] Specifically, reference can be made to Figure 1 the description of S102 in the illustrated embodiment, which will not be elaborated here.

[0071] S205, if the temperature difference is greater than or equal to the temperature preset value, then maintain the operation of the air conditioner based on the current air conditioner configuration parameters corresponding to the air conditioner dehumidification mode.

[0072] Optionally, the temperature preset value can refer to a value greater than 0, such as a value in the range of 2 - 6.

[0073] It is easy to understand that the current air conditioner configuration parameters can include parameters such as the opening degree of the electronically controlled expansion valve and the rotation frequency of the compressor configured in the current state.

[0074] In some embodiments, when the temperature difference between the return air dew point temperature and the evaporation temperature is greater than or equal to a preset temperature value, it can indicate that the evaporation temperature is lower than the return air dew point temperature. At this time, the water vapor in the air will adhere to the low-temperature evaporator and condense into dew, which will then be discharged outdoors through the water collecting tray and pipeline. Therefore, when the air conditioner operates under the current air conditioner configuration parameters corresponding to the dehumidification mode, the dehumidification effect can be achieved. Then, the air conditioner operation can be maintained according to the current air conditioner configuration parameters to maintain the dehumidification effect.

[0075] Suppose the current air conditioner configuration parameters refer to the opening degree of the electronic expansion valve and the rotation frequency of the compressor configured in the current state. Maintaining the air conditioner operation based on the current air conditioner configuration parameters corresponding to the dehumidification mode can be understood as maintaining the refrigerant transmission amount corresponding to the opening degree of the currently configured electronic expansion valve to transmit the refrigerant, and maintaining the current configured rotation frequency of the compressor to compress the refrigerant.

[0076] S206. If the temperature difference is less than the preset temperature value, obtain the first parameter adjustment step size and the first parameter adjustment period for the current air conditioner configuration parameters.

[0077] It is easy to understand that the first parameter adjustment step size refers to the adjustment step size of the opening degree of the electronic expansion valve.

[0078] Optionally, the preset temperature value can be set to 0. The preset temperature value in this step and the preset temperature value in S205 are preset values in different scenarios. Therefore, the preset temperature value in this step and the preset temperature value in S205 can be set to different values.

[0079] Optionally, the first parameter adjustment period can refer to the total adjustment duration of the opening degree of the electronic expansion valve. At this time, adjusting according to the first parameter adjustment period can mean that within the total adjustment duration, the refrigerant is continuously transmitted according to the transmission amount corresponding to the latest opening degree after adjusting the opening degree of the electronic expansion valve according to the adjustment step size, that is, within the total adjustment duration, the refrigerant is transmitted according to the transmission amount corresponding to the latest opening degree of the electronic expansion valve, and before or after the total adjustment duration, the refrigerant is transmitted according to the transmission amount corresponding to the original opening degree of the electronic expansion valve. In this scenario, the adjustment step size of the opening degree of the electronic expansion valve can be set to a relatively large step size.

[0080] Optionally, the first parameter adjustment period can refer to the unit adjustment period of the opening degree of the electronic expansion valve. At this time, adjusting according to the first parameter adjustment period can mean that when each unit adjustment period arrives, the opening degree of the electronic expansion valve is adjusted according to the adjustment step size until the opening degree of the electronic expansion reaches a preset opening value and the adjustment stops. In this scenario, the adjustment step size of the opening degree of the electronic expansion valve can be set to a relatively small step size.

[0081] In some embodiments, when the temperature difference between the return air dew point temperature and the evaporation temperature is less than a preset temperature value, it can indicate that the evaporation temperature is higher than the return air dew point temperature. At this time, the water vapor in the air encounters the high temperature of the evaporator and cannot condense into dew, let alone be discharged outdoors. Therefore, when the air conditioner operates with the current air conditioner configuration parameters corresponding to the dehumidification mode, the dehumidification effect cannot be achieved. Then, the pre-configured first parameter adjustment step and the first parameter adjustment period can be obtained. For example, the first parameter adjustment step can be a step with a relatively large value, and the first parameter adjustment period can be a total adjustment duration. The first parameter adjustment step can be a step with a relatively small value, and the first parameter adjustment period can be a unit adjustment period.

[0082] S207, perform operation adjustment on the first working configuration parameter of the electronic expansion valve based on the first parameter adjustment step and the first parameter adjustment period, and obtain the current air conditioner suction superheat.

[0083] It is easy to understand that the suction superheat refers to the difference obtained by subtracting the evaporation temperature from the suction temperature of the compressor.

[0084] The first working configuration parameter can refer to the opening degree of the electronic expansion valve. Adjusting the opening degree of the electronic expansion valve is also adjusting the liquid supply amount that the electronic expansion valve can transmit.

[0085] As described in S206, in the scenario where the first parameter adjustment step is a step with a relatively large value and the first parameter adjustment period is a total adjustment duration, performing operation adjustment on the first working configuration parameter of the electronic expansion valve based on the first parameter adjustment step and the first parameter adjustment period can be understood as adjusting the opening degree of the electronic expansion valve according to the first parameter adjustment step to obtain the latest opening degree of the electronic expansion valve. During the first parameter adjustment period, control the electronic expansion valve to maintain the transmission amount corresponding to the latest opening degree to transmit the refrigerant for air conditioner operation.

[0086] In a scenario where the first parameter adjustment step size can be a relatively small value and the first parameter adjustment period can be a unit adjustment period, adjusting the first operating configuration parameter of the electronic expansion valve based on the first parameter adjustment step size and the first parameter adjustment period can be understood as follows: when each first parameter adjustment period arrives, the existing opening degree of the electronic expansion valve is increased by the first parameter adjustment step size to obtain the updated opening degree of the electronic expansion valve. During the time period corresponding to the arrival moment of this first parameter adjustment period and the arrival moment of the next first parameter adjustment period, refrigerant is transmitted according to the transmission amount corresponding to the updated opening degree of the electronic expansion valve to operate the air conditioner. For example, when the first first parameter adjustment period arrives, the updated opening degree of the electronic expansion valve is equal to the sum of the existing opening degree of the electronic expansion valve and the first parameter adjustment step size. When the second parameter adjustment period arrives, the updated opening degree of the electronic expansion valve is equal to the sum of the aforementioned sum and the first parameter adjustment step size, and so on, until the updated opening degree of the electronic expansion valve reaches a preset opening degree threshold, at which point the adjustment of the opening degree of the electronic expansion valve can be stopped, and the refrigerant is transmitted according to the transmission amount corresponding to the latest updated opening degree of the electronic expansion valve to operate the air conditioner.

[0087] During the process of adjusting the first operating configuration parameter, the current air conditioner suction superheat can be obtained. Based on the obtained evaporation temperature, the difference between the suction temperature of the compressor and the evaporation temperature can be calculated to obtain the current air conditioner suction superheat.

[0088] S208, if the current air conditioner suction superheat is greater than or equal to the air conditioner superheat threshold, stop adjusting the electronic expansion valve and obtain the second parameter adjustment step size and the second parameter adjustment period.

[0089] It is easy to understand that the air conditioner superheat threshold refers to the maximum air conditioner superheat that can be achieved in the current air conditioner function mode.

[0090] The second parameter adjustment step size refers to the adjustment step size of the operating frequency of the compressor.

[0091] Optionally, the second parameter adjustment period can refer to the total adjustment duration of the operating frequency of the compressor. At this time, adjusting according to the second parameter adjustment period can mean that within the total adjustment duration, the refrigerant is compressed according to the latest operating frequency of the compressor obtained by adjusting the operating frequency of the compressor according to the adjustment step size, that is, within the total adjustment duration, the refrigerant is compressed according to the latest operating frequency of the compressor, and before or after the total adjustment duration, the refrigerant is compressed according to the original operating frequency of the compressor. In this scenario, the adjustment step size of the operating frequency of the compressor can be set to a relatively large value.

[0092] Optionally, the second parameter adjustment period may refer to a unit adjustment period of the compressor's operating frequency. At this time, adjusting according to the second parameter adjustment period may mean that when each unit adjustment period arrives, the compressor's operating frequency is adjusted according to the adjustment step until the compressor's operating frequency reaches a preset frequency value and stops adjusting. In this scenario, the adjustment step of the compressor's operating frequency may be set to a smaller step.

[0093] In some embodiments, during the air conditioning operation adjustment of the electronic expansion valve in S207, the return air dew point temperature and the evaporation temperature can still be monitored in real time, and the return air dew point temperature and the evaporation temperature measured at each moment can be compared. If the suction superheat also reaches the air conditioning superheat threshold during the air conditioning operation adjustment, and the evaporation temperature is always monitored to be higher than the return air dew point temperature, that is, the temperature difference between the return air dew point temperature and the evaporation temperature is always less than the temperature preset value (this temperature preset value refers to the temperature preset value in S206), it means that the current adjustment of the electronic expansion valve still cannot achieve the dehumidification effect, then the second parameter adjustment step and the second parameter adjustment cycle can be obtained to adjust the compressor.

[0094] It should be understood that the suction superheat plays a vital role in the normal operation of the electronic expansion valve. If the suction air has no superheat at all, it is possible that the return air will carry liquid, and even cause liquid hammer in the compressor and damage the compressor. In order to avoid this phenomenon, a certain suction superheat is required to ensure that only dry steam enters the compressor. However, too high suction superheat also has disadvantages. A high suction superheat will cause the compressor exhaust temperature (exhaust superheat) to increase, and the compressor operating conditions will deteriorate and the life will be reduced. Therefore, the suction superheat should be controlled within a certain range. The embodiment of the present application needs to monitor whether the suction superheat reaches the maximum suction superheat, that is, the air conditioning superheat threshold.

[0095] Optionally, during the process of adjusting the electronic expansion valve for air-conditioning operation in S207, the return air dew point temperature and the evaporation temperature can still be monitored in real time, and the magnitudes of the measured return air dew point temperature and the evaporation temperature at each moment can be compared. If during this air-conditioning operation adjustment process, the suction superheat is less than or equal to the air-conditioning superheat threshold, and at this time it is monitored that the evaporation temperature is lower than the return air dew point temperature, that is, the temperature difference between the return air dew point temperature and the evaporation temperature is always greater than the temperature preset value (this temperature preset value refers to the temperature preset value in S205), it means that the current adjustment of the electronic expansion valve can already achieve the dehumidification effect. Then, the opening degree of the electronic expansion valve corresponding to the current suction superheat can be maintained for air-conditioning operation. For example, within a certain first parameter adjustment period, if it is monitored that the temperature difference between the return air dew point temperature and the evaporation temperature is always greater than the temperature preset value, it indicates that the current adjustment operation can achieve the dehumidification effect. The current opening degree of the electronic expansion valve can be determined, and the adjustment of the opening degree of the electronic expansion valve can be stopped, and the refrigerant can be transmitted at the transmission amount corresponding to the current opening degree of the electronic expansion valve.

[0096] S209, perform up-frequency operation adjustment on the second working configuration parameter of the compressor based on the second parameter adjustment step and the second parameter adjustment period.

[0097] The second working configuration parameter can refer to the operating frequency of the compressor. Adjusting the operating frequency of the compressor is also adjusting the frequency at which the compressor compresses the refrigerant.

[0098] In some embodiments, as described in S208, in a scenario where the first parameter adjustment step is a relatively large step value and the first parameter adjustment period is the total adjustment duration, performing operation adjustment on the second working configuration parameter of the compressor based on the first parameter adjustment step and the first parameter adjustment period can be understood as adjusting the operating frequency of the compressor according to the first parameter adjustment step to obtain the latest operating frequency of the compressor, and within the first parameter adjustment period, controlling the compressor to maintain the latest operating frequency to compress the refrigerant.

[0099] In a scenario where the first parameter adjustment step size can be a relatively small value and the first parameter adjustment period can be a unit adjustment period, performing an operation adjustment on the second operating configuration parameter of the compressor based on the first parameter adjustment step size and the first parameter adjustment period can be understood as follows: when each first parameter adjustment period arrives, increasing the existing operating frequency of the compressor by the first parameter adjustment step size to obtain the updated operating frequency of the compressor, and during the time period corresponding to the arrival moment of this first parameter adjustment period and the arrival moment of the next first parameter adjustment period, compressing the refrigerant at the updated operating frequency of the compressor. For example, when the first first parameter adjustment period arrives, the updated operating frequency of the compressor is equal to the first sum value of the existing operating frequency of the compressor and the first parameter adjustment step size; when the second parameter adjustment period arrives, the updated operating frequency of the compressor is equal to the sum value of the aforementioned first sum value and the first parameter adjustment step size, and so on. The operating frequency of the compressor can be continuously adjusted, and the refrigerant can be compressed at the latest updated operating frequency of the compressor.

[0100] S210. If the temperature difference is greater than or equal to the temperature preset value, stop the adjustment control of the compressor.

[0101] In some embodiments, during the process of performing air-conditioning operation adjustment on the compressor in S209, the return air dew point temperature and the evaporation temperature can still be monitored in real time, and the magnitudes of the measured return air dew point temperature and the evaporation temperature at each moment can be compared. If during this air-conditioning operation adjustment process, it is monitored that the evaporation temperature is lower than the return air dew point temperature, that is, the temperature difference between the return air dew point temperature and the evaporation temperature is greater than or equal to the temperature preset value (this temperature preset value refers to the temperature preset value in S205), then it indicates that the current operating frequency of the compressor can achieve the dehumidification effect, and the adjustment control of the compressor can be stopped, that is, the operating frequency of the compressor is no longer increased. In this way, when the dehumidification effect can be achieved, there is no need to further increase the operating frequency of the compressor, and the energy-saving effect can be achieved.

[0102] S211. If the humidity demand degree is greater than or equal to the humidity demand degree threshold and the temperature demand degree is greater than or equal to the temperature demand degree threshold, execute the air-conditioning refrigeration mode.

[0103] Optionally, the humidity demand degree threshold can be set to 100%, and the temperature demand degree threshold can be set to a value less than 100% such as 90% or 86%.

[0104] In some embodiments, when it is determined that the humidity demand degree is greater than or equal to the humidity demand degree threshold, and the temperature demand degree is greater than or equal to the temperature demand degree threshold, it indicates that the temperature demand of the current environment is greater, that is, the temperature demand of the current environment is greater than the humidity demand, and cooling is required. Then, the air conditioner cooling mode can be executed, that is, the air conditioner can operate according to the relevant parameters corresponding to the air conditioner cooling mode.

[0105] S212, if the humidity demand degree is less than the humidity demand degree threshold, then execute the air conditioner cooling mode.

[0106] Optionally, the humidity demand degree threshold can be set to 100%.

[0107] In some embodiments, when it is determined that the humidity demand degree is less than the humidity demand degree threshold, it indicates that the humidity demand degree of the current environment is not large, and the cooling operation can be considered first. Then, the air conditioner cooling mode can be executed, that is, the air conditioner can operate according to the relevant parameters corresponding to the air conditioner cooling mode.

[0108] In the embodiments of the present application, first, according to the humidity demand degree and the temperature demand degree, it is determined whether to execute the air conditioner dehumidification mode or the air conditioner cooling mode. Then, during the process of determining to execute the air conditioner dehumidification mode, by monitoring the return air dew point temperature and the evaporation temperature, when the evaporation temperature is higher than the return air dew point temperature, first select to adjust the opening degree of the electronic expansion valve, and if the evaporation temperature still cannot be made lower than the return air dew point temperature after adjusting the electronic expansion valve, then select to adjust the frequency of the compressor. In this way, while ensuring a better dehumidification effect in the air conditioner dehumidification mode, the energy-saving effect is also ensured.
