[0068] Further, see Figure 1 The air conditioning system further includes a formaldehyde detection module 500 connected to the control device 100, which can be used to detect formaldehyde environmental status data of the indoor space, such as formaldehyde concentration.

[0069] In the embodiment of the present invention, refer to Figure 1 The control device 100 of the air conditioning system includes: a processor 1001, such as a CPU, a memory 1002, and a timer 1003.

[0070] Those skilled in the art will understand that Figure 1 The device structure shown in the figure does not constitute a limitation of the device, and may include more or less components than shown in the figure, or combine certain components, or arrange the components differently.

[0073] The embodiment of the present invention further provides a control method of an air conditioning system, which is applied to the above-mentioned air conditioning system.

[0074] Reference Figure 2 , an embodiment of a control method of an air conditioning system of the present application is proposed. In this embodiment, the control method of the air conditioning system includes:

[0075] Step S10, obtaining outdoor environmental data of the target space within a preset formaldehyde removal period;

[0076] The target space is specifically an indoor space conditioned by the air conditioning system.

[0077] The preset formaldehyde removal period is specifically a preset time period for the air conditioning system to remove formaldehyde. The air conditioning system needs to perform formaldehyde removal operation within the preset formaldehyde removal period and make the formaldehyde concentration in the target space less than or equal to the target formaldehyde concentration. The preset formaldehyde removal period can be determined by obtaining user configuration parameters, or by the air conditioning system based on user data characterized by monitoring data. For example, the start time of the formaldehyde removal period set by the user and the end time of the formaldehyde removal period set by the user can be obtained, and the time period between the start time and the end time is determined as the preset formaldehyde removal period, and the duration of the preset formaldehyde removal period is the preset duration.

[0078] The outdoor environment data specifically includes outdoor environment parameters corresponding to different times, and the outdoor environment parameters include at least one of the following: outdoor temperature, outdoor enthalpy value, and outdoor humidity.

[0079] The outdoor environmental data may include at least one of the following: predicted environmental data (such as weather forecast data, etc.), environmental data detected in the same period before the preset formaldehyde removal period (such as the same period on the same date, etc.), and environmental data actually detected in the preset formaldehyde removal period.

[0080] S10 may be executed within a preset formaldehyde removal period or before entering a preset formaldehyde removal period.

[0081] Step S20, determining a preset condition according to the outdoor environment data, wherein the preset condition includes a condition that the environmental parameter needs to satisfy when the outdoor heat energy is greater than the preset heat energy;

[0082] The environmental parameters here include indoor environmental parameters and / or outdoor environmental parameters.

[0083] Different outdoor environmental data correspond to different preset conditions. The preset conditions are specifically used to distinguish between high outdoor heat energy periods and low outdoor heat energy periods within the preset formaldehyde removal period. When the environmental parameters within the period meet the preset conditions, it indicates that the outdoor heat energy within the period is greater than the preset heat energy. When the environmental parameters within the period do not meet the preset conditions, it indicates that the outdoor heat energy within the period is less than or greater than the preset heat energy.

[0084] The preset conditions include critical parameter values ​​corresponding to indoor environmental parameters and / or outdoor environmental parameters. The critical parameter values ​​can be determined based on the indoor environmental parameters and / or outdoor environmental parameters. The critical parameter values ​​can include upper and / or lower limits of the environmental parameters. Specifically, the critical parameter values ​​here can be calculated by substituting outdoor environmental data into a preset algorithm model. Alternatively, the critical parameter values ​​can be obtained by filtering the outdoor environmental data after processing the outdoor environmental data according to preset rules.

[0085] The preset conditions include the quantitative relationship that needs to be satisfied between the indoor environmental parameters and / or the outdoor environmental parameters and the preset environmental parameters, and the quantitative relationship can be determined according to the outdoor environmental data. Specifically, a preset algorithm model between the indoor environmental parameters and / or the outdoor environmental parameters and the preset environmental parameters can be established in advance, and the quantitative relationship here is obtained after the model parameters in the preset algorithm model are determined according to the outdoor environmental data.

[0086] In this embodiment, the environmental parameter includes outdoor temperature, and the preset condition includes that the outdoor temperature is greater than or equal to a critical temperature; and / or, the environmental parameter includes outdoor enthalpy value, and the preset condition includes that the outdoor enthalpy value is greater than or equal to a critical enthalpy value.

[0087] Step S30, within the preset formaldehyde removal time period, control the ventilation operation of the fresh air fan, control the heating operation of the air conditioner according to the first formaldehyde removal temperature within the time period that meets the preset conditions, and control the heating operation of the air conditioner or control the air conditioner to shut down according to the second formaldehyde removal temperature within the time period that does not meet the preset conditions, wherein the first formaldehyde removal temperature is greater than the second formaldehyde removal temperature.

[0088] The ventilation volume during the ventilation operation of the fresh air fan can be a preset ventilation volume, or a ventilation volume determined according to the actual operating conditions of the air conditioning system.

[0089] The preset formaldehyde removal time period can detect the environmental parameters of the environment in which the air conditioning system is located in real time or at set intervals to determine whether the environmental parameters meet the preset conditions. When the environmental parameters meet the preset conditions, the air conditioner can be controlled to heat according to the first formaldehyde removal temperature; when the environmental parameters do not meet the preset conditions, the air conditioner can be controlled to heat or shut down according to the second formaldehyde removal temperature.

[0090] When controlling the heating operation of the air conditioner according to the first formaldehyde removal temperature, the indoor temperature of the target space can be detected, and the heating operation of the air conditioner can be controlled according to the first temperature difference between the indoor temperature and the first formaldehyde removal temperature. For example, the operating frequency of the compressor in the air conditioner is determined according to the first temperature difference.

[0091] When controlling the heating operation of the air conditioner according to the second formaldehyde removal temperature, the indoor temperature of the target space can be detected, and the heating operation of the air conditioner can be controlled according to the second temperature difference between the indoor temperature and the second formaldehyde removal temperature. For example, the operating frequency of the compressor in the air conditioner is determined according to the second temperature difference.

[0092] Among them, the first control mode is defined as controlling the heating operation of the air conditioner according to the second formaldehyde removal temperature, and the second control mode is defined as controlling the air conditioner to shut down. During the period when the preset conditions are not met, the indoor formaldehyde concentration, outdoor ambient temperature and outdoor enthalpy value can be obtained, and the target control mode is determined from the first control mode and the second control mode according to the indoor formaldehyde concentration, outdoor ambient temperature and outdoor enthalpy value, and the air conditioner operation is controlled according to the target control mode.

[0093] A control method for an air conditioning system is proposed in an embodiment of the present invention. The method determines preset conditions based on outdoor environmental data within a preset formaldehyde removal period of a target space. During the preset formaldehyde removal period, during the ventilation operation of a fresh air fan, the preset conditions are used to distinguish between a first period of high outdoor thermal energy and a second period of low outdoor thermal energy. During the period of higher outdoor thermal energy, the air conditioner is controlled to heat according to a higher first formaldehyde removal temperature. During the period of lower outdoor thermal energy, the air conditioner is controlled to heat or shut down according to a lower second formaldehyde removal temperature. During the formaldehyde removal process, the air conditioner no longer operates at a fixed formaldehyde removal temperature, but can change to adapt to the impact of the outdoor air introduced on the indoor temperature. The outdoor thermal energy is fully utilized to assist the air conditioner in adjusting the indoor temperature, while avoiding the high energy consumption required for the air conditioner to reach a higher formaldehyde removal temperature under low outdoor temperature conditions. The formaldehyde removal demand can be met while reducing the energy consumption of the air conditioner.

[0094] Further, based on the above embodiment, another embodiment of the control method of the air conditioning system of the present application is proposed. In this embodiment, the preset formaldehyde removal period includes at least two sub-periods. In this instantiation, the sub-period is one hour. In other embodiments, the sub-period may also be 4 hours, 8 hours, one day, etc. The outdoor environment data includes outdoor environment parameters corresponding to different sub-periods, refer to Figure 3 , the step of determining the preset condition according to the outdoor environment data comprises:

[0095] Step S21, accumulating the duration of corresponding sub-periods in descending order according to the outdoor heat energy represented by the outdoor environmental parameters, until the accumulated duration is greater than or equal to the predicted formaldehyde removal duration, wherein the predicted formaldehyde removal duration includes the predicted formaldehyde removal duration of the target space under a preset state, and the preset state includes controlling the operation of the air conditioner in the air conditioning system at a first formaldehyde removal temperature;

[0096] In the process of duration accumulation, the outdoor environmental parameters of all sub-durations included in the preset formaldehyde removal period are arranged in order from large to small according to the outdoor heat represented. After sorting, the sub-durations corresponding to the outdoor environmental parameters are arranged in order of duration 1, duration 2, duration 3, duration 4... duration n. The initial cumulative duration is duration 1, and the execution is repeated: when the current cumulative duration is less than the predicted formaldehyde removal duration, the sub-durations sorted later are accumulated on the basis of the current cumulative duration to obtain a new cumulative duration, until the current cumulative duration is greater than or equal to the predicted formaldehyde removal duration. The sub-duration used in the accumulation process according to the current cumulative duration can be used as the target sub-duration, and the preset conditions here can be determined according to the outdoor environmental parameters corresponding to all target sub-durations in the preset formaldehyde removal period.

[0097] Step S22: determining the preset condition according to all outdoor environmental parameters corresponding to the accumulated time.

[0098] In one implementation of this embodiment, the critical temperature is determined according to all outdoor environmental parameters corresponding to the accumulated duration, and the preset condition includes that the outdoor environmental temperature is greater than or equal to the critical temperature. In this embodiment, the preset condition is determined by determining the minimum temperature among all the outdoor environmental temperatures corresponding to the accumulated duration, and specifically determining the minimum temperature as the critical temperature.

[0099] In another implementation of this embodiment, the critical enthalpy value is determined according to all outdoor environmental parameters corresponding to the cumulative duration, and the preset condition includes that the outdoor environmental enthalpy value is greater than or equal to the critical enthalpy value. In this embodiment, the preset condition is determined by determining the minimum enthalpy value among all the outdoor environmental enthalpy values ​​corresponding to the cumulative duration, and specifically determining the minimum enthalpy value as the critical enthalpy value.

[0100] In this embodiment, through the above method, the cumulative duration can accurately characterize the temperature corresponding to the high thermal energy period outdoors during the entire preset formaldehyde removal period. Therefore, the preset conditions are determined based on the outdoor environmental parameters corresponding to the cumulative duration, and accurate distinction between high and low thermal energy periods within the preset formaldehyde removal period can be achieved, thereby further ensuring that the target formaldehyde removal effect is achieved while effectively saving the energy consumption of the air conditioner.

[0101] Furthermore, in the present embodiment, the step of obtaining outdoor environmental data within a preset formaldehyde removal period of the target space includes: determining a first environmental parameter corresponding to each sub-period based on weather forecast data of the area where the target space is located, and detecting a second environmental parameter of the current outdoor environment; determining the outdoor environmental parameter corresponding to each sub-period based on the first environmental parameter and the second environmental parameter.

[0102] When the outdoor environmental parameters include the predicted outdoor temperature, the first outdoor temperature of each sub-period can be determined according to the weather forecast data, the second outdoor temperature currently detected by the above-mentioned outdoor detection module can be obtained, and the predicted outdoor temperature can be determined according to the first outdoor temperature and the second outdoor temperature.

[0103] When the outdoor environmental parameters include outdoor predicted enthalpy values, the first outdoor enthalpy value of each sub-period can be determined according to weather forecast data, the second outdoor enthalpy value currently detected by the above-mentioned outdoor detection module can be obtained, and the outdoor predicted enthalpy value can be determined according to the first outdoor enthalpy value and the second outdoor enthalpy value.

[0104] When determining the outdoor environmental parameter according to the first environmental parameter and the second environmental parameter, one of the first environmental parameter and the second environmental parameter can be determined as the outdoor environmental parameter according to the relationship between the first environmental parameter and the second environmental parameter, or the outdoor environmental parameter can be calculated by substituting the first environmental parameter and the second environmental parameter into a preset formula.

[0105] In this embodiment, it is helpful to improve the accuracy of outdoor environmental parameters in representing outdoor environmental conditions within the preset formaldehyde removal period, thereby ensuring that the preset conditions determined based on the outdoor environmental parameters are more accurate, and further achieving a balance between formaldehyde removal effect and energy saving and consumption reduction of the air conditioner.

[0106] Furthermore, in this embodiment, the step of determining the outdoor environmental parameter corresponding to each sub-period based on the first environmental parameter and the second environmental parameter includes: determining a deviation value between the first environmental parameter and the second environmental parameter; when the deviation value is less than a preset threshold, determining that the first environmental parameter is the outdoor environmental parameter; when the deviation value is greater than or equal to the preset threshold, correcting the first environmental parameter according to the second environmental parameter to obtain the outdoor environmental parameter.

[0107] Specifically, the correction value can be determined according to the parameter interval where the second environmental parameter is located, and the first environmental parameter can be corrected according to the correction value to obtain the outdoor environmental parameter. Alternatively, the correction value can be calculated by the second environmental parameter, and the first environmental parameter can be corrected according to the correction value to obtain the outdoor environmental parameter.

[0108] In this embodiment, the above method is helpful to further improve the accuracy of outdoor environmental parameters, thereby further ensuring the formaldehyde removal effect while improving the energy saving and consumption reduction effect of the air conditioner.

[0109] Further, based on any of the above embodiments, another embodiment of the control method of the air conditioning system of the present application is proposed. In this embodiment, the preset formaldehyde removal period includes at least two unit periods. In this embodiment, the unit period is one day. In other embodiments, the unit period may also be 3 days, one week, one month, etc. Each of the unit periods includes at least two sub-periods, and the duration of the sub-period is less than the unit period. Figure 4 The step of obtaining outdoor environmental data of the target space within a preset formaldehyde removal period includes:

[0110] Step S11, obtaining environmental status data corresponding to each unit time period, wherein the environmental status data includes a currently predicted first outdoor environmental parameter, a second outdoor environmental parameter detected in the same time period in the past, and a historical correspondence, wherein the historical correspondence includes a relationship between different sub-time periods in the same time period in the past and the outdoor environmental parameter;

[0111] The first outdoor environment parameter specifically represents the overall outdoor environment state in a unit time period. The second outdoor environment parameter specifically represents the overall outdoor environment parameter in the same time period in the past.

[0112] The first outdoor environmental parameter is specifically obtained by acquiring weather forecast data. In the present embodiment, the first outdoor environmental parameter is the average outdoor parameter of the predicted unit time period. Specifically, the average outdoor parameter can be determined according to the outdoor parameter range of the unit time period in the weather forecast. For example, the first outdoor environmental parameter is the first average outdoor temperature, which can be determined as the first average outdoor temperature according to the average of the maximum temperature and the minimum temperature in the outdoor temperature range of the unit time period in the weather forecast. For another example, the first outdoor environmental parameter is the first average outdoor enthalpy value, which can be determined as the first average outdoor enthalpy value according to the average of the maximum enthalpy value and the minimum enthalpy value in the outdoor enthalpy value range of the unit time period in the weather forecast.

[0113] The same period in the past is specifically the same period as the corresponding unit period in the past date. Wrong. The second outdoor environmental parameter is specifically the average outdoor parameter in the same period in the past. For example, the second outdoor environmental parameter is the second average outdoor temperature, and the average of all outdoor temperatures detected in the same period in the past can be determined as the second average outdoor temperature.

[0114] In other embodiments, the first outdoor environment parameter may be the minimum outdoor environment parameter of the unit time period currently predicted, and the second outdoor environment parameter may be the minimum outdoor environment parameter actually detected in the same time period in the past. Alternatively, the first outdoor environment parameter may be the maximum outdoor environment parameter of the unit time period currently predicted, and the second outdoor environment parameter may be the maximum outdoor environment parameter actually detected in the same time period in the past.

[0115] The historical corresponding relationship is specifically determined according to the outdoor environmental parameters actually detected in different sub-periods of the same period in the past.

[0116] Step S12, determining the outdoor environmental data according to the first outdoor environmental parameter, the second outdoor environmental parameter and the historical correspondence of each unit time period, wherein the outdoor environmental data includes the outdoor environmental parameters corresponding to each sub-time period within the preset formaldehyde removal time period.

[0117] In one implementation, an adjustment parameter is determined according to the first outdoor environment parameter and the second outdoor environment parameter in each unit time period, the corresponding historical correspondence is adjusted according to the adjustment parameter, and the outdoor environment data here is determined according to all adjusted historical correspondences.

[0118] In another implementation, the relationship value between the outdoor environment parameter corresponding to each sub-period in the historical correspondence and the second outdoor environment parameter can be determined, and the first outdoor environment parameter can be corrected according to the relationship value corresponding to each sub-period in the unit period to obtain the outdoor environment parameter corresponding to each sub-period.

[0119] Among them, the first outdoor environmental parameter includes the first outdoor temperature, the second outdoor environmental parameter includes the second outdoor temperature, the historical correspondence includes the relationship between different sub-periods in the same period in the past and the outdoor environmental temperature, and the corresponding outdoor environmental data includes the outdoor predicted temperature corresponding to each sub-period in the preset formaldehyde removal period.

[0120] The second outdoor environmental parameter includes the first outdoor enthalpy value, the second outdoor environmental parameter includes the second outdoor enthalpy value, the historical correspondence includes the relationship between different sub-periods in the same period in the past and the outdoor environmental enthalpy value, and the corresponding outdoor environmental data includes the outdoor predicted enthalpy value corresponding to each sub-period in the preset formaldehyde removal period.

[0121] In this embodiment, through the above-mentioned method, when it is impossible to directly predict the outdoor environmental parameters of each sub-period within a unit time period, for example, the weather forecast can only predict the temperature range or enthalpy range of the unit time period, etc., it is also possible to analyze the outdoor environmental parameters corresponding to each sub-period within the preset formaldehyde removal period by combining historical data and the currently predictable unit time period data. Based on this, the accuracy of the air conditioner control within the preset formaldehyde removal period based on the outdoor environmental parameters is guaranteed, thereby further ensuring that the target formaldehyde removal effect is achieved while saving energy consumption.

[0122] Furthermore, in the present embodiment, the step of determining the outdoor environment data according to the first outdoor environment parameter, the second outdoor environment parameter and the historical correspondence of each unit time period includes: determining the relationship value between the first outdoor environment parameter and the second outdoor environment parameter; adjusting the historical correspondence corresponding to each unit time period according to the relationship value to obtain the first correspondence of each unit time period, the first correspondence being the relationship between each sub-time period within the unit time period and the outdoor environment parameter, and the outdoor environment data including the set of all the first correspondences.

[0123] In this embodiment, the relationship value is the ratio of the first outdoor environment parameter to the second outdoor environment parameter. In other embodiments, the relationship value may also be the difference between the first outdoor environment parameter and the second outdoor environment parameter.

[0124] In this embodiment, the relationship value between the outdoor environment parameter corresponding to a certain time period in the first corresponding relationship and the outdoor environment parameter corresponding to the same time period in the historical corresponding relationship is equal to the relationship value between the first outdoor environment parameter and the second outdoor environment parameter.

[0125] In order to better understand the solution of this embodiment, a specific example of using the solution of this embodiment to determine outdoor environment data is listed below:

[0126] Assuming that the user's given cycle is 500h (that is, the preset formaldehyde removal cycle), according to the formaldehyde concentration and temperature relationship curve and the indoor formaldehyde release concentration state to be achieved, it is deduced that the time required according to the maximum heating setting temperature of 30℃ (the first formaldehyde removal temperature) is 280h, and then according to the user's decoration materials, housing area, and fresh air ventilation rate, the actual time at the set temperature of 30℃ is calculated and corrected to 300h (predicted formaldehyde removal time);

[0127] By obtaining the weather forecast for the same date last year for 500 hours, the temperature change curve for each day within 500 hours (the historical corresponding relationship for the unit time period) can be obtained. Because the weather forecast for the future can only obtain a temperature range for the whole day after more than 72 hours, this method obtains the ratio Q (the relationship between the first environmental parameter and the second environmental parameter) of the average temperature of the same day last year and this year, assuming it is 1.2, and combines the temperature change curve for each day last year to obtain the temperature change curve for each day within 500 hours this year (the first corresponding relationship), thereby obtaining the temperature change curve for the entire 500 hours (outdoor environmental data).

[0128] According to the actual duration, a high temperature period of 300 hours is screened out from the 500-hour temperature curve, and the temperature is screened from high to low. When the cumulative screening time is equal to 300 hours, the temperature value corresponding to the screening is the critical temperature, which is assumed to be 26°C.

[0129] In this embodiment, the above method can further improve the accuracy of the actual outdoor environment conditions within the preset formaldehyde removal period represented by the outdoor environment data, thereby further ensuring the target formaldehyde removal effect while reducing the energy consumption of the air conditioner.

[0130] Furthermore, in the present embodiment, before the step of accumulating the duration of corresponding sub-periods in order from large to small according to the outdoor heat energy characterized by the outdoor environmental parameters until the accumulated duration obtained is greater than or equal to the predicted formaldehyde removal duration, it also includes: when the current moment is in the preset formaldehyde removal time period, determining that the unit time period before the current moment is in the preset formaldehyde removal time period is the target unit time period, and obtaining a second corresponding relationship detected in the target unit time period, the second corresponding relationship being the relationship between the actual outdoor environmental parameters changing over time; and correcting the predicted formaldehyde removal time according to the comparison result of the second corresponding relationship corresponding to the target unit time period and the first corresponding relationship.

[0131] In one implementation, a relationship characteristic value between a first correspondence corresponding to a target unit time period and an outdoor environmental parameter corresponding to the same time period in a second correspondence is determined, and a correction value is determined based on the relationship characteristic value to correct the predicted formaldehyde removal time.

[0132] In another implementation, the magnitude relationship between the outdoor environmental parameters corresponding to the same time period in the first corresponding relationship and the second corresponding relationship is determined, and a correction value is determined based on the magnitude relationship to correct the predicted formaldehyde removal time.

[0133] In this embodiment, the second corresponding relationship and the first corresponding relationship can accurately reflect the deviation between the actual formaldehyde removal time and the predicted formaldehyde removal time when the air conditioner is controlled at the first formaldehyde removal temperature during the preset formaldehyde removal period. Therefore, the predicted formaldehyde removal time is corrected based on the above method and then the preset conditions are determined based on the corrected predicted formaldehyde removal time, thereby avoiding the control error of the air conditioner caused by the prediction deviation, and ensuring that the operation of the air conditioner can accurately achieve the target formaldehyde removal effect while minimizing energy consumption.

[0134] Further, based on any of the above embodiments, another embodiment of the control method of the air conditioning system of the present application is proposed. In this embodiment, after the step of obtaining the environmental status data corresponding to each of the unit time periods, it also includes: when the duration of the preset formaldehyde removal period is less than or equal to the maximum duration range allowed by the predicted first outdoor environmental parameter, the outdoor environmental data is determined according to the first outdoor environmental parameter, the second outdoor environmental parameter and the historical correspondence of each of the unit time periods; when the duration of the preset formaldehyde removal period is greater than the maximum duration range, the first target time period corresponding to the maximum duration range with the current moment as the starting moment in the preset formaldehyde removal period is determined, and the time period after the first target time period in the preset formaldehyde removal period is determined as the second target time period, and the third correspondence of the first target time period is determined according to the first outdoor environmental parameter, the second outdoor environmental parameter and the historical correspondence corresponding to each unit time period in the first target time period, and the fourth correspondence of the second target time period is determined according to the historical correspondence of each unit time period in the second target time period, and the outdoor environmental data includes the third correspondence and the fourth correspondence;

[0135] The third corresponding relationship and the fourth corresponding relationship are both relationships between outdoor environmental parameters changing with time.

[0136] When the duration of the preset formaldehyde removal period is less than or equal to the maximum duration, it indicates that the first outdoor environmental parameters of each unit period in the preset formaldehyde removal period can be predicted. When the duration of the preset formaldehyde removal period is greater than the maximum duration, it indicates that the first outdoor environmental parameters of some unit periods in the preset formaldehyde removal period cannot be predicted.

[0137] The first outdoor environmental parameters of each unit time period in the first target time period here can be predicted, and the first outdoor environmental parameters of each unit time period in the second target time period here cannot be predicted.

[0138] The corresponding first corresponding relationship is determined according to the first outdoor environmental parameters, the second outdoor environmental parameters and the historical corresponding relationship corresponding to each unit time period within the first target time period. The first corresponding relationship here refers to the same concept as the above-mentioned first corresponding relationship, and the third corresponding relationship includes the set of all first corresponding relationships corresponding to the first target time period.

[0139] The fourth corresponding relationship includes all historical corresponding relationships corresponding to the second target period.

[0140] The third corresponding relationship includes the outdoor environmental parameters corresponding to each sub-period in the first target period, and the fourth corresponding relationship includes the outdoor environmental parameters corresponding to each sub-period in the second target period.

[0141] In this embodiment, through the above method, even if the preset formaldehyde removal period is too long and exceeds the predicted duration range of the current outdoor environmental parameters, the correspondence between the sub-period corresponding to the full period in the preset formaldehyde removal period and the outdoor environmental parameters can be obtained, thereby further improving the accuracy of air conditioner control in the preset formaldehyde removal period, achieving the target formaldehyde removal effect while further improving the energy-saving effect.

[0142] Furthermore, in this embodiment, after the step of obtaining the environmental status data corresponding to each unit time period, the step further includes:

[0143] When the duration of the preset formaldehyde removal period is greater than the maximum duration, and the current moment is within the preset formaldehyde removal period, the period before the first target period within the preset formaldehyde removal period is determined as the third target period, and the fifth corresponding relationship of the third target period is determined according to the actual outdoor environmental parameters corresponding to each unit period within the third target period, the second outdoor environmental parameters and the historical corresponding relationship, the outdoor environmental data includes the fifth corresponding relationship, the third corresponding relationship and the fourth corresponding relationship, and the fifth corresponding relationship is the relationship between the outdoor environmental parameters and time;

[0144] When the duration of the preset formaldehyde removal period is greater than the maximum duration range and the current moment is before the preset formaldehyde removal period, the outdoor environment data includes the third corresponding relationship and the fourth corresponding relationship.

[0145] When the duration of the preset formaldehyde removal period is greater than the maximum duration range, in addition to determining the first target period, the second target period, the third corresponding relationship and the fourth corresponding relationship mentioned above, the third target period and the fifth corresponding relationship are also determined.

[0146] Here, the execution order of the process of determining the third target period and the fifth corresponding relationship and the process of determining the first target period and the second target period, the third corresponding relationship, and the fourth corresponding relationship is not specifically limited.

[0147] In the process of determining the fifth corresponding relationship, the relationship characteristic value between the actual outdoor environment parameter corresponding to each unit time period and the second outdoor environment parameter can be used, and the corresponding historical corresponding relationship can be adjusted according to the relationship characteristic value corresponding to each unit time period to obtain the corresponding sub-corresponding relationship. The sub-corresponding relationship includes the outdoor environment parameters corresponding to each sub-time period in the corresponding unit time period. The fifth corresponding relationship includes the set of all sub-corresponding relationships corresponding to the third target time period.

[0148] In this embodiment, on the basis of ensuring the corresponding relationship between the sub-period corresponding to the full period within the preset formaldehyde removal period and the outdoor environmental parameters, the influence of the deviation between the actual outdoor environmental conditions and the predicted first outdoor environmental parameters can also be avoided, ensuring that the air conditioner operates at the first formaldehyde removal temperature within the preset formaldehyde removal period. The duration required to meet the target formaldehyde removal effect can accurately reach the duration required, thereby ensuring the target formaldehyde removal effect while effectively improving the energy saving effect.

[0149] Further, based on any of the above embodiments, the control method of the air conditioning system further includes:

[0150] Obtain a state parameter, wherein the state parameter represents a relationship between the duration of the preset formaldehyde removal period and the predicted formaldehyde removal duration of the target space under a preset state, wherein the preset state includes controlling the heating operation of the air conditioner and the ventilation operation of the fresh air fan at a first formaldehyde removal temperature; when the state parameter meets a target condition, execute step S10, wherein the target condition represents that the duration of the preset formaldehyde removal period is greater than the predicted formaldehyde removal duration.

[0151] The state parameters may include first-category parameters related to the duration of formaldehyde removal in the target space under a preset state and second-category parameters related to the control of the duration of formaldehyde removal in a preset formaldehyde removal period. The first-category parameters include but are not limited to at least one of the following: predicted formaldehyde removal duration, first formaldehyde removal temperature, historical formaldehyde removal duration, etc. The second-category parameters include but are not limited to at least one of the following: duration of a preset formaldehyde removal period, target formaldehyde removal temperature required, target formaldehyde concentration change value, etc.

[0152] The predicted formaldehyde removal time is specifically the shortest time required for the target space to achieve the target formaldehyde removal effect under the preset state. The predicted formaldehyde removal time can be determined based on the actual state parameters of the monitored target space, or based on the parameters input by the user.

[0153] The first formaldehyde removal temperature is specifically the target ambient temperature that the target space needs to reach during the formaldehyde removal process. In the present embodiment, the first formaldehyde removal temperature is the highest formaldehyde removal temperature. In other embodiments, the first formaldehyde removal temperature may also be other formaldehyde removal temperatures that are lower than the highest formaldehyde removal temperature, or may be a temperature set by a user.

[0154] Among them, the preset state may further include the fresh air fan operating with a preset ventilation volume.

[0155] Among them, the target condition indicates that the duration of the preset formaldehyde removal period is greater than the predicted formaldehyde removal period, the outdoor heat energy corresponding to the first period is greater than the outdoor heat energy of the second period, and the first formaldehyde removal temperature is greater than the second formaldehyde removal temperature.

[0156] If the state parameters meet the target conditions, it can be considered that the air conditioner maintains a high formaldehyde removal temperature as the target output during the entire preset formaldehyde removal period, which will result in excess heat output from the air conditioner when the target formaldehyde removal effect is achieved in the target space, resulting in unnecessary energy consumption; if the state parameters do not meet the target conditions, it can be considered that the air conditioner needs to maintain a high formaldehyde removal temperature output during the entire preset formaldehyde removal period to ensure that the target space can achieve the target formaldehyde removal effect or the deviation from the target formaldehyde removal effect is minimal. The target formaldehyde removal effect here specifically means that the formaldehyde concentration in the target space at the end of the preset formaldehyde removal period is less than or equal to the target formaldehyde concentration.

[0157] In one implementation, the state parameter includes the predicted formaldehyde removal time and the duration of the preset formaldehyde removal period, and the target condition includes that the duration of the preset formaldehyde removal period is greater than the predicted formaldehyde removal time;

[0158] In another implementation, the state parameter includes the target formaldehyde removal temperature required for the preset formaldehyde removal period and the first formaldehyde removal temperature, and the target condition includes that the first formaldehyde removal temperature is greater than the target formaldehyde removal temperature. The target formaldehyde removal temperature here is specifically determined according to the preset duration of the preset formaldehyde removal period, and different preset durations correspond to different target formaldehyde removal temperatures, and the target formaldehyde removal temperature is negatively correlated with the preset duration.

[0159] In this embodiment, when it is determined through state parameters that the duration of the preset formaldehyde removal period is longer than the formaldehyde removal time required when the air conditioner is operating at the first formaldehyde removal temperature, during the ventilation process of the new fan, the air conditioner is controlled to heat according to the higher first formaldehyde removal temperature during the period when the outdoor thermal energy is higher, and the air conditioner is controlled to heat or shut down according to the lower second formaldehyde removal temperature during the period when the outdoor thermal energy is lower. The air conditioner no longer operates at a fixed formaldehyde removal temperature during the formaldehyde removal process, and fully utilizes the outdoor thermal energy to assist the air conditioner in regulating the indoor temperature. At the same time, the high energy consumption required for the air conditioner to reach a higher formaldehyde removal temperature under low outdoor temperature conditions is avoided, which can meet the formaldehyde removal needs while reducing the energy consumption of the air conditioner.

[0160] Furthermore, in this embodiment, the state parameters include the predicted formaldehyde removal time and the duration of the preset formaldehyde removal period, and the step of obtaining the predicted formaldehyde removal time includes: obtaining the formaldehyde concentration of the target space and the ventilation operation parameters of the fresh air fan; determining the predicted formaldehyde removal time according to the formaldehyde concentration, the ventilation operation parameters and the first formaldehyde removal temperature.

[0161] The formaldehyde concentration can be specifically detected by the above-mentioned formaldehyde detection module.

[0162] Different formaldehyde concentrations, ventilation operating parameters and first formaldehyde removal temperatures correspond to different predicted formaldehyde removal times.

[0163] The correspondence between formaldehyde concentration, ventilation operation parameters, first formaldehyde removal temperature and predicted formaldehyde removal time can be preset, and the correspondence may include a calculation formula, a training model, etc. Based on the correspondence, the predicted formaldehyde removal time corresponding to the current formaldehyde concentration, ventilation operation parameters and first formaldehyde removal temperature can be determined.

[0164] The corresponding relationship here can be a pre-set fixed corresponding relationship, or it can be different according to the actual operating conditions of the air conditioning system. In this embodiment, the space size parameters of the target space are obtained; the target relationship between the formaldehyde concentration, the ventilation operation parameters, the first formaldehyde removal temperature and the predicted formaldehyde removal time is obtained according to the space size parameters; the predicted formaldehyde removal time corresponding to the formaldehyde concentration, the ventilation operation parameters and the first formaldehyde removal temperature is determined according to the target relationship. The space size parameters include at least one of the following: volume, length, width and height, building area, ground area, etc. Different space size parameters correspond to different target relationships.

[0165] In this embodiment, the relationship between the formaldehyde concentration, the ventilation operation parameters, the first formaldehyde removal temperature, the space size parameters and the predicted formaldehyde removal time can be seen in the following formula:

[0166] t=[(V*C*Q G ) / (V G *C G *Q)]*t G ;

[0167] Among them, V is the volume of the target space, C is the formaldehyde concentration in the target space, Q is the ventilation volume of the fresh air fan, and Q G is the standard ventilation volume of the fresh air fan, C G is the standard formaldehyde concentration, V G The standard ventilation volume, standard formaldehyde concentration and standard volume can all be determined according to the first formaldehyde removal temperature. If the first formaldehyde removal temperature is different, the standard ventilation volume, standard formaldehyde concentration and / or standard volume will be different.

[0168] It should be noted that the formula here is only to more intuitively show the relationship between the above parameters and the predicted formaldehyde removal time, and is not used to limit the method of determining the predicted formaldehyde removal time. Other forms of corresponding relationships between the parameters that satisfy the relationship reflected by the above formula may also be within the scope of protection of the present invention.

[0169] In this embodiment, the above method is helpful to improve the accuracy of predicting the formaldehyde removal time, thereby further ensuring the accuracy of air conditioner control within the preset formaldehyde removal period, so as to further ensure the formaldehyde removal effect while saving air conditioning energy efficiency.

[0170] In addition, an embodiment of the present invention further proposes a storage medium on which a control program of an air conditioning system is stored. When the control program of the air conditioning system is executed by a processor, the relevant steps of any embodiment of the control method of the air conditioning system are implemented.
