[0063] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, 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. Apparently, the described embodiments are some but not all of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0064] The following disclosure provides many different embodiments or examples for implementing different structures of the present invention. To simplify the disclosure of the present invention, components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numerals and / or letters in different examples. Such repetition is for the purpose of simplification and clarity and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0065] To solve the technical problem in the prior art that when an air conditioner unit includes multiple indoor units installed in different rooms, multiple humidity sensors need to be configured, which significantly increases the hardware cost of the air conditioner unit and reduces the user experience, the present application provides a control method for air conditioner operation, which can replace the humidity sensors of the indoor units with a single humidity detection module of the outdoor unit, and there is no need to independently configure sensors for each indoor unit. Therefore, the outdoor relative humidity obtained by the humidity detection module of the outdoor unit can be used to replace the indoor relative humidity. Since there is a certain correlation between the outdoor relative humidity and the indoor relative humidity, therefore, according to the outdoor relative humidity, the evaporation temperature during air conditioner operation can be accurately determined, and thus the air conditioner operation can be controlled according to the evaporation temperature to ensure that the indoor humidity is within a reasonable range and improve the comfort, achieving the improvement of the indoor environmental humidity comfort while reducing the air conditioner hardware cost.

[0066] The following further explains the control method for air conditioner operation provided by the present application with specific examples in conjunction with the accompanying drawings. The examples do not constitute a limitation to the embodiments of the present application.

[0067] See Figure 1 , which is a flowchart of an embodiment of a control method for air conditioner operation provided by an embodiment of the present application. As Figure 1 shown, the process may include the following steps:

[0068] Step 101: When the indoor unit is turned on, obtain the current outdoor relative humidity through the humidity detection module.

[0069] The above-mentioned indoor unit refers to the component installed indoors in the air conditioner, which realizes the treatment of indoor air humidity or temperature (such as dehumidification or humidification) by adjusting the evaporation temperature.

[0070] The above-mentioned outdoor unit refers to the component installed outdoors in the air conditioner, which cooperates with the indoor unit to complete the adjustment of the air environment by the indoor unit.

[0071] The above-mentioned humidity detection module is used to measure the relative humidity of the environment where it is located. In the embodiment of the present application, this humidity detection module can be installed on the outdoor unit to measure the relative humidity value of the outdoor environment.

[0072] The above-mentioned outdoor relative humidity refers to the current relative humidity of the environment where the outdoor unit is located, which refers to the percentage of the water vapor pressure in the outdoor air to the saturated water vapor pressure at the same temperature, and reflects the degree to which the water vapor in the air approaches the saturated state.

[0073] In the embodiment of the present application, the execution subject of the embodiment of the present application can be an air conditioner. Further, the execution subject of the embodiment of the present application can also be a controller installed in the air conditioner. The air conditioner can include an indoor unit and an outdoor unit. The embodiment of the present application does not limit the number of indoor units and outdoor units, that is, the indoor unit can be one or more, and the outdoor unit can also be one or more. Among them, when there is one outdoor unit, one humidity detection module can be installed on it; when there are multiple outdoor units, since they are all in the outdoor environment, in order to save hardware costs, only one of the multiple outdoor units can be installed with a humidity detection module. When there are multiple indoor units, since the indoor environments where they are located are different and the corresponding relative humidities are also different, if you want to obtain the relative humidity of each indoor unit in the room, you need to install a humidity detection module for each indoor unit, which increases the hardware cost of the air conditioner.

[0074] Based on this, in the embodiment of the present application, the air conditioner can install a humidity detection module on one outdoor unit. In this case, when the indoor unit of the air conditioner is turned on, when controlling the indoor air humidity at this time, in order to improve user comfort and make the indoor humidity within a preset range, the execution subject of the embodiment of the present application can obtain the current outdoor relative humidity through the humidity detection module. And because there is a certain correlation between the indoor relative humidity and the outdoor relative humidity. For example, when the indoor unit of the air conditioner has not been turned on for a long time, the indoor relative humidity is the same as the outdoor relative humidity. Therefore, the operation of the air conditioner can be controlled according to the outdoor relative humidity.

[0075] As an alternative implementation, the execution entity of the embodiments of the present application may send a preset control instruction to the humidity detection module of the outdoor unit. After receiving the control instruction, the humidity detection module may obtain the outdoor relative humidity of the current outdoor environment and send the outdoor relative humidity to the execution entity of the embodiments of the present application.

[0076] As another alternative implementation, the execution entity of the embodiments of the present application may obtain in real time the outdoor relative humidity obtained by the humidity detection module installed in the outdoor unit and store the outdoor relative humidity in a preset storage medium. Based on this, when the execution entity of the embodiments of the present application detects that the indoor unit is turned on, it may obtain the current outdoor relative humidity from the above storage medium.

[0077] Step 102: Determine the evaporation temperature during the operation of the air conditioner according to the above outdoor relative humidity.

[0078] Step 103: Control the operation of the air conditioner based on the above evaporation temperature.

[0079] The following is a unified description of Step 102 and Step 103:

[0080] The above evaporation temperature refers to the temperature at which the refrigerant evaporates from a liquid state to a gaseous state in the evaporator and is one of the core parameters in the air-conditioning refrigeration cycle. In the embodiments of the present application, the operation of the air conditioner is controlled by controlling the evaporation temperature inside the air conditioner.

[0081] In the embodiments of the present application, since there is a certain correlation between the outdoor relative humidity of the outdoor environment and the indoor relative humidity of the indoor environment in practical applications, in the embodiments of the present application, after obtaining the outdoor relative humidity, the evaporation temperature during the operation of the air conditioner may be determined according to the outdoor relative humidity, so as to control the operation of the air conditioner based on the evaporation temperature, so that the relative humidity inside the user's room can be guaranteed to be within a preset range during the operation of the air conditioner, thereby ensuring the comfort of the user's environment.

[0082] As an alternative implementation, since the outdoor relative humidity is the same as the indoor relative humidity when the indoor unit has not been turned on for a long time, when the execution entity of the embodiments of the present application determines the evaporation temperature during the operation of the air conditioner according to the outdoor relative humidity, it may first obtain the most recent historical time when the indoor unit was last operated.

[0083] After that, the time interval between the current moment and the most recent historical time may be determined. Based on this, it may be determined whether the time interval is greater than or equal to a preset duration threshold. The above duration threshold may be a preset duration standard value representing whether the outdoor relative humidity is the same as the indoor relative humidity.

[0084] Optionally, when it is determined that the time interval is greater than or equal to the above duration threshold, it indicates that the outdoor relative humidity is the same as the indoor relative humidity at this time. Therefore, the outdoor relative humidity can be directly used as the indoor relative humidity to determine the evaporation temperature during air conditioner operation.

[0085] Optionally, when it is determined that the time interval is less than the above duration threshold, in order to more accurately determine the indoor relative humidity, the execution entity of the embodiment of the present application can pre-construct the corresponding relationship between the outdoor temperature value, the outdoor relative humidity, and the indoor relative humidity, and construct a relative humidity correction model for the outdoor relative humidity according to this corresponding relationship.

[0086] Based on this, the execution entity of the embodiment of the present application can obtain the current outdoor temperature value, and determine the indoor relative humidity corresponding to the indoor unit according to this outdoor temperature value, the outdoor relative humidity, and the above-mentioned pre-constructed relative humidity model.

[0087] As an exemplary implementation, a temperature detection module, such as a temperature sensor, can be pre-installed on the outdoor unit of the air conditioner. Based on this, the execution entity of the embodiment of the present application can obtain the outdoor temperature value of the outdoor environment where the outdoor unit is located through the temperature detection module installed on the outdoor unit.

[0088] As an exemplary implementation, the above outdoor temperature value and outdoor relative humidity can be input into the above relative humidity correction model to obtain the indoor relative humidity corresponding to the indoor unit output by the relative humidity correction model.

[0089] After that, the evaporation temperature during air conditioner operation can be determined according to the above indoor relative humidity.

[0090] As another alternative implementation, in order to save computing resources, the execution entity of the embodiment of the present application can pre-construct the corresponding relationship between the outdoor temperature value, the outdoor relative humidity, and the indoor relative humidity, and construct a relative humidity correction model for the outdoor relative humidity according to this corresponding relationship.

[0091] Based on this, after the execution entity of the embodiment of the present application obtains the outdoor relative humidity, it can obtain the current outdoor temperature value, and determine the indoor relative humidity corresponding to the indoor unit according to this outdoor temperature value, the outdoor relative humidity, and the above-mentioned pre-constructed relative humidity model.

[0092] As an exemplary implementation, a temperature detection module, such as a temperature sensor, can be pre-installed on the outdoor unit of the air conditioner. Based on this, the execution entity of the embodiment of the present application can obtain the outdoor temperature value of the outdoor environment where the outdoor unit is located through the temperature detection module installed on the outdoor unit.

[0093] As an exemplary embodiment, the above outdoor temperature value and outdoor relative humidity can be input into the above relative humidity correction model to obtain the indoor relative humidity corresponding to the indoor unit output by the relative humidity correction model.

[0094] After that, the evaporation temperature during air conditioner operation can be determined according to the above indoor relative humidity.

[0095] As for how to determine the evaporation temperature during air conditioner operation according to the outdoor relative humidity or indoor relative humidity specifically, it can be described in the following through Figure 3 the shown process, which will not be elaborated here in detail. Among them, Figure 3 describes how to determine the evaporation temperature during air conditioner operation according to the outdoor relative humidity specifically. This method can also be applied to determine the evaporation temperature during air conditioner operation according to the indoor relative humidity. It only differs in the description of the outdoor relative humidity and indoor relative humidity. Therefore, in the embodiments of the present application, how to determine the evaporation temperature during air conditioner operation according to the indoor relative humidity specifically will not be elaborated again.

[0096] In an embodiment, after determining the evaporation temperature during air conditioner operation, the execution subject of the embodiments of the present application can control the air conditioner operation based on this evaporation temperature, that is, during the process of air conditioner operation, the evaporation temperature of the air conditioner is made to reach the determined evaporation temperature by controlling the operation parameters of the air conditioner.

[0097] As an optional implementation manner, the compressor frequency can directly affect the refrigerant pressure in the evaporator, thereby changing the evaporation temperature, and it can be negatively correlated with the evaporation temperature, that is, the greater the compressor frequency, the lower the evaporation temperature. Based on this, the execution subject of the embodiments of the present application can adjust the evaporation temperature of the air conditioner by controlling the compressor frequency of the compressor in the air conditioner.

[0098] As another optional implementation manner, controlling the opening degree of the electronic expansion valve inside can control the refrigerant flow rate, thereby controlling the evaporation temperature. The opening degree of this electronic expansion valve can be positively correlated with the evaporation temperature, that is, the smaller the opening degree of the electronic expansion valve, the less refrigerant flows into the evaporator, and the lower the evaporation temperature. Based on this, the execution subject of the embodiments of the present application can adjust the evaporation temperature of the air conditioner by controlling the opening degree of the electronic expansion valve in the air conditioner.

[0099] In an embodiment, the process of the execution subject of the embodiments of the present application controlling the air conditioner operation based on the evaporation temperature can be the pre-control when the indoor unit of the air conditioner is turned on. Therefore, the air conditioner operation can be controlled based on this evaporation temperature within a preset duration. The above preset duration can be a period of time set in advance after the indoor unit is turned on, such as 1 hour, or 50 minutes, etc.

[0100] After that, after passing through the above preset duration, control the air conditioner to operate according to the set operation mode.

[0101] The technical solution provided by the embodiments of the present application, when the indoor unit is turned on, obtains the current outdoor relative humidity through the humidity detection module, determines the evaporation temperature during the operation of the air conditioner according to the above outdoor relative humidity, and controls the operation of the air conditioner based on the above evaporation temperature. This technical solution replaces the humidity sensor of the indoor unit with a single humidity detection module of the outdoor unit, and there is no need to independently configure a sensor for each indoor unit. Therefore, the outdoor relative humidity obtained by the humidity detection module of the outdoor unit can replace the indoor relative humidity. Since there is a certain correlation between the outdoor relative humidity and the indoor relative humidity, according to the outdoor relative humidity, the evaporation temperature during the operation of the air conditioner can be accurately determined, so that the operation of the air conditioner can be controlled according to the evaporation temperature to ensure that the indoor humidity is within a reasonable range and improve comfort. While improving the humidity comfort of the indoor environment, the hardware cost of the air conditioner is reduced.

[0102] See Figure 2 , which is a flowchart of an embodiment of another control method for air conditioner operation provided by the embodiments of the present application. Figure 2 The process shown Figure 1 On the basis of the process shown, the prerequisite for obtaining the outdoor relative humidity is described. As Figure 2 shown, the process may include the following steps:

[0103] Step 201: When the indoor unit is turned on, obtain the historical time when the indoor unit was last turned off.

[0104] Step 202: Determine the time interval from the last shutdown to the current startup of the indoor unit according to the current time and the above historical time.

[0105] Step 203: Determine whether the above time interval is greater than a preset time interval threshold; if so, execute Step 204; if not, execute Step 207.

[0106] The following is a unified description of Steps 201 to 203:

[0107] The above historical time refers to the historical time point when the air conditioner was last turned off before the current operation.

[0108] The above time interval threshold can be a preset duration standard for characterizing whether the outdoor relative humidity can be used as the indoor relative humidity. It can be 20 minutes or other durations. The embodiments of the present application do not limit this.

[0109] In the embodiments of the present application, since the relative humidity of the indoor environment can be equivalent to the relative humidity of the outdoor environment when the indoor unit has not been turned on for a long time, in order to improve the accuracy of determining the indoor relative humidity, the execution entity of the embodiments of the present application can first obtain the historical time when the indoor unit was last turned off before obtaining the current outdoor relative humidity through the humidity detection module.

[0110] After that, based on the current time and the above historical time, the time interval from the last shutdown of the indoor unit to the current startup can be determined, and it can be determined whether this time interval is greater than a preset time interval threshold.

[0111] Optionally, when it is determined that the above time interval is greater than the above time interval threshold, it indicates that the indoor unit has not been started for a long time at this time. The outdoor relative humidity can be equated to the indoor relative humidity, and the following step 204 can be executed.

[0112] Optionally, when it is determined that the above time interval is less than or equal to the above time interval threshold, it indicates that the time interval between the current startup of the indoor unit and the last startup is short. Since the indoor relative humidity was adjusted during the last operation of the indoor unit, there is a certain difference between the outdoor relative humidity and the indoor relative humidity at this time. Step 207 can be continued to be executed.

[0113] Step 204: Obtain the current outdoor relative humidity through the humidity detection module.

[0114] Step 205: Determine the evaporation temperature during air conditioner operation based on the above outdoor relative humidity.

[0115] Step 206: Control the operation of the air conditioner based on the above evaporation temperature.

[0116] For the detailed description of steps 204 to 206, reference can be made to the description of steps 101 to 103, which will not be elaborated here.

[0117] Step 207: Obtain the historical relative humidity recorded when the indoor unit was last shut down.

[0118] Step 208: Determine the new evaporation temperature during air conditioner operation based on the above historical relative humidity.

[0119] Step 209: Control the operation of the air conditioner based on the above new evaporation temperature.

[0120] The following is a unified description of steps 207 to 209:

[0121] The above historical relative humidity refers to the relative humidity after the indoor environment was adjusted and recorded during the last operation of the indoor unit.

[0122] In the embodiments of the present application, when it is determined that the time interval from the last startup when the indoor unit is started is long, since there is a difference between the outdoor relative humidity and the indoor relative humidity at this time, therefore, in order to more accurately obtain the current indoor relative humidity, the execution entity of the embodiments of the present application can obtain the historical relative humidity recorded when the indoor unit was last shut down.

[0123] After that, the evaporation temperature during the operation of the air conditioner can be determined based on the historical relative humidity (hereinafter referred to as the "new evaporation temperature" for easy distinction). After that, the operation of the air conditioner can be controlled based on the new evaporation temperature.

[0124] Furthermore, since the indoor relative humidity may change over time, after obtaining the above-mentioned historical relative humidity, the execution subject of the embodiment of the present application can adjust the historical relative humidity to obtain the target historical relative humidity.

[0125] As an optional implementation manner, a first linear relationship between the indoor relative humidity and time can be pre-constructed. Based on this, the relative humidity change value can be determined from the first linear relationship according to the above-mentioned time interval. After that, the historical relative humidity can be adjusted according to the relative humidity change value to obtain the target historical relative humidity.

[0126] As another optional implementation manner, since there are differences in the humidity changes of the air in different seasons, the execution subject of the embodiment of the present application can pre-construct a second linear relationship between the time corresponding to different seasons and the outdoor relative humidity. After that, the current season can be obtained first, and the target second linear relationship corresponding to the current season can be determined. Then, the target relative humidity change value can be determined from the target second linear relationship according to the above-mentioned time interval. Finally, the historical relative humidity can be adjusted according to the target relative humidity change value to obtain the target historical relative humidity.

[0127] After that, the evaporation temperature during the operation of the air conditioner can be determined based on the target historical relative humidity.

[0128] Among them, the method for determining the new evaporation temperature during the operation of the air conditioner based on the historical relative humidity or the target historical relative humidity is the same as Figure 3 the method for determining the evaporation temperature during the operation of the air conditioner based on the outdoor relative humidity described in the shown process, which will not be elaborated in the present application.

[0129] As for the method for controlling the operation of the air conditioner based on the new evaporation temperature, it is the same as the method for controlling the operation of the air conditioner based on the evaporation temperature, which will not be elaborated in the present application either.

[0130] The technical solution provided by the embodiment of this application, when the indoor unit is turned on, obtains the historical time when the indoor unit was last turned off, determines the time interval from the last shutdown of the indoor unit to the current startup according to the current time and the above historical time, and determines whether the above time interval is greater than a preset time interval threshold; if so, obtains the current outdoor relative humidity through the humidity detection module, determines the evaporation temperature during air conditioner operation according to the above outdoor relative humidity, and controls the air conditioner operation based on the above evaporation temperature; if not, obtains the historical relative humidity recorded when the indoor unit was last turned off, determines the new evaporation temperature during air conditioner operation according to the above historical relative humidity, and controls the air conditioner operation based on the above new evaporation temperature. This technical solution dynamically selects outdoor humidity or historical humidity as the basis for adjusting the evaporation temperature by judging the on-off time interval of the indoor unit. Among them, if the indoor unit shuts down for a short time, the change in indoor humidity is small, and the historical humidity data recorded at the last shutdown can be directly called to avoid repeated reliance on outdoor humidity detection and improve control efficiency; if the indoor unit has not been turned on for a long time, the indoor humidity is usually close to the outdoor humidity. At this time, the outdoor humidity can be directly used as the adjustment basis without waiting for the real-time detection of the indoor humidity sensor, and the optimal evaporation temperature can be predicted and started directly according to the outdoor humidity, reducing the energy waste at the initial stage of startup.

[0131] See Figure 3 , which is a flowchart of an embodiment of another control method for air conditioner operation provided by the embodiment of this application. Figure 3 The process shown Figure 1 or Figure 2 On the basis of the process shown, it describes how to determine the evaporation temperature during air conditioner operation according to the outdoor relative humidity specifically. As Figure 3 shown, the process may include the following steps:

[0132] Step 301: Determine the dew point temperature during air conditioner operation according to the outdoor relative humidity.

[0133] The above dew point temperature refers to the temperature at which the water vapor in the air reaches the saturation state and begins to condense into liquid water under a fixed air pressure. In the embodiment of this application, this dew point temperature can be used as the core parameter connecting outdoor humidity detection and the air conditioner dehumidification function.

[0134] In the embodiment of this application, the execution subject of the embodiment of this application can determine the dew point temperature during air conditioner operation according to the above outdoor relative humidity, so as to determine the evaporation temperature during air conditioner operation according to this dew point temperature in the following steps.

[0135] As an alternative implementation, the execution entity of the embodiments of the present application may obtain the ambient temperature value where the indoor unit is currently located, and perform a preset operation on the ambient temperature value and the outdoor relative humidity to obtain the dew point temperature during air conditioner operation. The above ambient temperature value refers to the temperature value in the environment where the indoor unit is currently located, which can represent the indoor temperature value.

[0136] As an exemplary implementation, when determining the above dew point temperature, a preset first adjustment parameter and a second adjustment parameter may be obtained, and the ambient temperature value may be adjusted according to the first adjustment parameter and the second adjustment parameter to determine the ambient temperature adjustment value. The above first adjustment parameter and second adjustment parameter may be pre-calibrated parameter values. The above first adjustment parameter may be 17.62 or other values, and the embodiments of the present application do not limit this. The above second adjustment parameter may be 243.12 or other values, and the embodiments of the present application do not limit this.

[0137] As an implementation, the ambient temperature value may be adjusted through the following formula (I) to determine the ambient temperature adjustment value:

[0138]

[0139] Where T1 above is the ambient temperature adjustment value, A above is the first adjustment parameter, B above is the second adjustment parameter, and T above is the ambient temperature value.

[0140] After that, an intermediate parameter may be determined according to the above outdoor relative humidity and ambient temperature adjustment value.

[0141] As an implementation, the logarithm of the outdoor relative humidity may be determined, and the logarithm value may be added to the ambient temperature adjustment value to obtain the intermediate parameter. For example, the intermediate parameter may be determined through the following formula (II):

[0142] C = log(RH / 100) + T1 Formula (II)

[0143] Where RH above is the outdoor relative humidity, T1 above is the ambient temperature adjustment value, and C above is the intermediate parameter.

[0144] Finally, a linear operation may be performed on the above first adjustment parameter, second adjustment parameter, and intermediate parameter to obtain the dew point temperature during air conditioner operation.

[0145] As an implementation, the second adjustment parameter may be multiplied by the intermediate parameter to obtain a first value, and the first adjustment parameter may be subtracted from the intermediate parameter to obtain a second value. Then, the first value is divided by the second value to obtain the above dew point temperature. For example, the dew point temperature may be determined through the following formula (III):

[0146]

[0147] Wherein, D is the dew point temperature, A is the first adjustment parameter, B is the second adjustment parameter, and C is the intermediate parameter.

[0148] Step 302: Determine the evaporation temperature range during the operation of the air conditioner according to the above outdoor relative humidity and dew point temperature.

[0149] Step 303: Determine any evaporation temperature included in the above evaporation temperature range as the evaporation temperature during the operation of the air conditioner.

[0150] The following is a unified description of Step 302 and Step 303:

[0151] The above evaporation temperature range refers to the range of the evaporation temperature reached during the operation of the air conditioner when the air conditioner needs to meet the current dehumidification conditions.

[0152] In the embodiment of the present application, in order to meet the current humidity adjustment requirements, the execution subject of the embodiment of the present application can determine the evaporation temperature range during the operation of the air conditioner according to the outdoor relative humidity and the determined dew point temperature. Based on this, any evaporation temperature within the evaporation temperature range can be determined as the evaporation temperature during the operation of the air conditioner. That is, when the evaporation temperature during the operation of the air conditioner is within this evaporation temperature range, the current dehumidification requirements can be met.

[0153] As an optional implementation manner, when determining the evaporation temperature range, it is possible to determine the target relative humidity range to which the outdoor relative humidity belongs among a plurality of preset relative humidity ranges. Thereafter, the evaporation temperature range during the operation of the air conditioner can be determined according to the target relative humidity range and the dew point temperature.

[0154] As an exemplary embodiment, the above-mentioned plurality of preset relative humidity ranges include three relative humidity ranges: less than the first relative humidity threshold, greater than or equal to the first relative humidity threshold and less than or equal to the second relative humidity threshold, and greater than the second relative humidity threshold. Wherein, the second relative humidity threshold may be greater than the first relative humidity threshold. For example, the first relative humidity threshold may be 60%, and the second relative humidity threshold may be 80%.

[0155] Based on this, when it is determined that the target relative humidity range to which the outdoor relative humidity belongs is less than the first relative humidity threshold, it can be determined that the evaporation temperature range during the operation of the air conditioner is greater than the dew point temperature. This can ensure that the air conditioner does not dehumidify during operation and keeps the humidity stable. Since the evaporation temperature is relatively high at this time, the air conditioner load is small, the unit energy consumption is low, and the air conditioner operates energy-efficiently.

[0156] When it is determined that the target relative humidity range to which the outdoor relative humidity belongs is greater than or equal to the first relative humidity threshold and less than or equal to the second relative humidity threshold, the evaporation temperature range during air conditioner operation can be determined to be greater than the difference between the dew point temperature and the first preset value. The above first preset value can be a pre-calibrated constant value, and its setting range can be between 0 and 10. This can ensure proper dehumidification during air conditioner operation, maintain humidity stability. Since the evaporation temperature is relatively high at this time, the air conditioner load is small, and the unit energy consumption is low, so the air conditioner operation is relatively energy-saving.

[0157] When it is determined that the target relative humidity range to which the outdoor relative humidity belongs is greater than the second relative humidity threshold, the evaporation temperature range during air conditioner operation can be determined to be less than the difference between the dew point temperature and the second preset value. The above second preset value can be a pre-calibrated constant value, and its setting range can be between 0 and 10, and the second preset value is greater than the first preset value. This can ensure dehumidification of the indoor air environment during air conditioner operation, reduce indoor humidity, and ensure comfort.

[0158] Among them, when the outdoor relative humidity is low, the first preset value is small, which can ensure proper dehumidification of the unit while the unit energy consumption is low; when the outdoor relative humidity is high, the second preset value is large, at this time the evaporation temperature is large, the compressor output is large, and the frequency is high. In this case, rapid dehumidification can be achieved to ensure comfort.

[0159] The technical solution provided by the embodiments of the present application determines the dew point temperature during air conditioner operation according to the outdoor relative humidity, determines the evaporation temperature range during air conditioner operation according to the above outdoor relative humidity and dew point temperature, and determines any evaporation temperature included in the above evaporation temperature range as the evaporation temperature during air conditioner operation. This technical solution dynamically determines the evaporation temperature range and specific value by associating and calculating the outdoor relative humidity and the dew point temperature. It uses the thermodynamic principle to convert the humidity parameter into a calculable temperature threshold, providing a low-cost and high-efficiency humidity management solution for air conditioner systems without indoor humidity sensors, achieving the improvement of the accuracy and energy efficiency of humidity regulation while reducing the hardware cost.

[0160] See Figure 4 , which is a flowchart of an embodiment of another air conditioner operation control method provided by the embodiments of the present application. Figure 4 The process shown in Figure 1 or Figure 3 On the basis of the process shown, it describes dynamically determining the evaporation temperature during air conditioner operation according to the current season. As Figure 4 shown, this process may include the following steps:

[0161] Step 401, determine the initial evaporation temperature during air conditioner operation according to the outdoor relative humidity.

[0162] The above initial evaporation temperature is the evaporation temperature during the operation of the air conditioner determined according to the outdoor relative humidity.

[0163] In the embodiments of the present application, the execution subject of the embodiments of the present application may first determine an initial evaporation temperature during the operation of the air conditioner according to the outdoor relative humidity.

[0164] As for how to determine the initial evaporation temperature during the operation of the air conditioner according to the outdoor relative humidity, reference may be made to Figure 3 the process shown, which will not be elaborated here.

[0165] Step 402: Determine the current season.

[0166] Step 403: Adjust the initial evaporation temperature according to the current season to obtain the evaporation temperature during the operation of the air conditioner.

[0167] The following is a unified description of steps 402 and 403:

[0168] The above outdoor temperature value refers to the temperature value of the outdoor environment where the outdoor unit is currently located.

[0169] The above current season refers to the season where the outdoor environment is currently located, which may include but is not limited to: summer and winter.

[0170] In the embodiments of the present application, in order to improve the comfort of the user, after the execution subject of the embodiments of the present application determines the initial evaporation temperature during the operation of the air conditioner according to the outdoor relative humidity, in order to make the control of the air conditioner operation more in line with the current season, the current season may be determined, and the initial evaporation temperature may be adjusted according to the current season to obtain the evaporation temperature during the operation of the air conditioner.

[0171] As an optional implementation manner, the outdoor temperature value where the outdoor unit is currently located may be obtained, and the current season may be determined according to the outdoor temperature value.

[0172] As an optional implementation manner, when it is determined that the outdoor temperature value is greater than the first temperature threshold, the current season may be determined as the first season with a higher temperature, such as summer; when it is determined that the outdoor temperature value is less than the second temperature threshold, the current season may be determined as the second season with a lower temperature, such as winter.

[0173] As another optional implementation manner, the current weather forecast may be obtained through the network, and the current season may be determined according to the weather forecast.

[0174] As an optional implementation, when the initial evaporation temperature is adjusted according to the current season, when the current season is the first season with a higher temperature, since the high temperature and high humidity environment in the actual environment is prone to breed bacteria, the initial evaporation temperature can be reduced by a first preset temperature to improve the dehumidification effect of the air conditioner; when the current season is the second season with a lower temperature, since the room needs to be heated when the temperature is lower and the room should not be too dry, the initial evaporation temperature can be increased by a second preset temperature to reduce the dehumidification effect of the air conditioner. The first preset temperature and the second preset temperature can be the same or different, and the embodiment of the present application does not limit this.

[0175] In addition, the execution subject of the embodiment of the present application can also obtain the current weather forecast and predict the change of outdoor relative humidity in the future preset time period according to the weather forecast. Based on this, the initial evaporation temperature can be adjusted according to the change of outdoor relative humidity to obtain the evaporation temperature when the air conditioner is running.

[0176] As an implementation mode, when the change in outdoor relative humidity indicates a decrease in relative humidity, the initial evaporation temperature may be increased by a third preset temperature to reduce the dehumidification effect of the air conditioner; when the change in outdoor relative humidity indicates an increase in relative humidity, the initial evaporation temperature may be reduced by a fourth preset temperature to improve the dehumidification effect of the air conditioner. The third preset temperature and the fourth preset temperature may be the same or different, and the embodiment of the present application does not limit this.

[0177] The technical solution provided in the embodiment of the present application determines the initial evaporation temperature when the air conditioner is running according to the outdoor relative humidity, determines the current season, and adjusts the initial evaporation temperature according to the current season to obtain the evaporation temperature when the air conditioner is running. This technical solution dynamically adjusts the evaporation temperature according to the outdoor relative humidity and seasonal characteristics, realizes the precise matching of humidity control and seasonal environment, thereby improving the comfort of air conditioning dehumidification.

[0178] To facilitate understanding of the air conditioning operation control method provided in the present application, an exemplary description is given below:

[0179] See also Figure 5 , is a flow chart of an embodiment of a method for controlling air conditioning operation provided in an embodiment of the present application. Figure 5 As shown, the process may include:

[0180] In the embodiment of the present application, in view of the situation where the indoor unit of the air conditioner does not have a humidity sensor, the outdoor unit is configured with a humidity sensor, and the humidity sensor of the outdoor unit can detect the relative humidity of the environment.

[0181] Among them, when the air conditioner indoor unit in a certain room has not been turned on for a long time, its indoor environmental temperature and relative humidity will approach the outdoor unit environmental temperature and outdoor environmental relative humidity infinitely. At this time, the relative humidity of the outdoor environment can be detected by the humidity sensor of the outdoor unit, and the environmental humidity detected by the humidity sensor of the outdoor unit is used to replace the indoor environmental humidity.

[0182] Based on this, when the air conditioner indoor unit in this room is turned on, this humidity parameter can be used to adjust the air conditioner operation load. When the humidity is relatively high, the air conditioner load output can be increased, the evaporation temperature can be reduced, so that the air conditioner can dehumidify during operation, reduce the indoor humidity, and improve the comfort; when the humidity is relatively low, the air conditioner load output can be reduced, the evaporation temperature can be increased, and the humidity can be kept within a reasonable range, which can reduce the air conditioner energy consumption and achieve the energy-saving effect.

[0183] When the relative humidity of the outdoor environment is detected At this time, within 1 hour after starting up, the dew point temperature is calculated through the relative humidity, and the evaporation temperature Te of the air conditioner during operation is controlled to be > the dew point temperature Tl, that is, it can be ensured that the air conditioner does not dehumidify during operation and the humidity is kept stable. Since the evaporation temperature is relatively high at this time, the air conditioner load is small, the unit energy consumption is low, and the air conditioner operates energy-efficiently.

[0184] When the relative humidity of the outdoor environment is detected When it is between 60% and 80%, within 1 hour after starting up, the dew point temperature is calculated through the relative humidity, and the evaporation temperature Te of the air conditioner during operation is controlled to be > the dew point temperature Tl - a, that is, it can be ensured that the air conditioner dehumidifies appropriately during operation and the humidity is kept stable. Since the evaporation temperature is relatively high at this time, the air conditioner load is small, the unit energy consumption is low, and the air conditioner operates relatively energy-efficiently.

[0185] When the relative humidity of the outdoor environment is detected At this time, within 1 hour after starting up, the dew point temperature is calculated through the relative humidity, and the evaporation temperature Te of the air conditioner during operation is controlled to be < the dew point temperature Tl - b, which can ensure that the air conditioner dehumidifies the indoor air environment during operation, reduces the indoor humidity, and ensures comfort.

[0186] The technical solution provided by the embodiment of the present application is that when the air conditioner indoor unit has not been turned on for a long time, the indoor environmental temperature and relative humidity will approach the outdoor unit environmental temperature and outdoor environmental relative humidity infinitely. At this time, the relative humidity of the outdoor environment can be detected by the humidity sensor of the outdoor unit, and the environmental humidity detected by the humidity sensor of the outdoor unit is used to replace the indoor environmental humidity, which is mainly applied to the control in the early stage of startup. This technical solution uses the environmental relative humidity detected by the humidity sensor of the outdoor unit to replace the environmental relative humidity of the indoor air conditioner room that has not been turned on, and adjusts the evaporation temperature according to this relative humidity when the indoor unit is turned on to regulate the room air environment. Since the method of judging the environmental humidity of the indoor air conditioner room that has not been turned on by the humidity sensor of the outdoor unit according to the present invention and adjusting the room environment according to this humidity when the indoor unit is turned on improves the indoor environmental comfort, reduces the indoor air conditioner hardware cost, and makes the air conditioner operation more energy-efficient.
