[0046] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0047] An embodiment of the present invention provides an air conditioning system.

[0048] In the embodiment of the present invention, refer to Figure 1 The air conditioning system includes a control device 100, an air conditioner 200, and a fresh air blower 300. The air conditioner 200 and the fresh air blower 300 are both connected to the control device 100.

[0049] In this embodiment, the air conditioner 200 is a multi-split air conditioner, and the air conditioner 200 is used to adjust the temperature of at least two indoor spaces. The multi-split air conditioner includes at least two indoor units, which are respectively arranged in different indoor spaces to adjust the air in different indoor spaces, wherein each indoor unit includes an indoor heat exchanger and a control valve connected in series with the indoor heat exchanger, and the indoor heat exchanger is correspondingly provided with an indoor fan. In some embodiments, the air conditioner 200 may also be an air conditioner 200 independently arranged in a space, such as a cabinet air conditioner, a window air conditioner, a wall-mounted air conditioner, etc.

[0050] In this embodiment, the fresh air fan 300 can introduce outdoor fresh air into the room and exhaust indoor air to the outside. The fresh air fan 300 is used to adjust the fresh air of at least two indoor spaces. The fresh air fan 300 can include more than one air outlet module, which are respectively arranged in different indoor spaces to adjust the air of different indoor spaces. In some embodiments, the fresh air fan 300 can also be independently arranged in a fresh air device in a space.

[0051] Further, see Figure 1 The air conditioning system further includes an environment detection module 400 connected to the control device 100, which may include an indoor detection module and / or an outdoor detection module for detecting indoor and / or outdoor air state parameters (such as temperature, air pressure, humidity, etc.).

[0052] 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 state parameters in the indoor space, such as formaldehyde concentration.

[0053] 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. Among them, these components are connected and communicated through a communication bus. The memory 1002 can be a high-speed RAM memory or a stable memory (non-volatile memory), such as a disk memory. The memory 1002 can also be a storage device independent of the aforementioned processor 1001.

[0054] 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.

[0055] like Figure 1As shown, the memory 1002 as a computer storage medium may include a control program for the air conditioning system.

[0056] exist Figure 1 In the device shown, the processor 1001 can be used to call the control program of the air conditioning system stored in the memory 1002, and execute the relevant steps of the control method of the air conditioning system in the following embodiments.

[0057] 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.

[0058] 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:

[0059] Step S10, obtaining a state parameter, wherein the state parameter represents a relationship between a preset formaldehyde removal period of the target space and a predicted formaldehyde removal period 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;

[0060] 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 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.

[0061] The prediction duration is specifically the shortest duration required for the target space to achieve the target formaldehyde removal effect under the preset state. The prediction duration can be determined based on the actual state parameters of the monitored target space, or based on the parameters input by the user.

[0062] 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.

[0063] Among them, the preset state may further include the fresh air fan operating with a preset ventilation volume.

[0064] Here, step S10 may be performed before entering the preset formaldehyde removal period of the target space or when entering the preset formaldehyde removal period.

[0065] Step S20, when the state parameter meets the target condition, the fresh air fan is controlled to operate for ventilation, the air conditioner is controlled to operate for heating according to the first formaldehyde removal temperature in a first period of the preset formaldehyde removal period, and the air conditioner is controlled to operate for heating or shut down according to the second formaldehyde removal temperature in a second period of the preset formaldehyde removal period;

[0066] Among them, the target condition indicates that the duration of the preset formaldehyde removal period is greater than the predicted duration, 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.

[0067] 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.

[0068] In one implementation, the state parameter includes the predicted duration 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 duration;

[0069] 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.

[0070] 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.

[0071] 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.

[0072] The preset formaldehyde removal period can be divided into a first period and a second period. The first period and the second period can be fixed periods pre-set before entering the preset formaldehyde removal period, or can be periods divided within the preset formaldehyde removal period based on whether preset conditions are met.

[0073] The indoor temperature of the target space is detected during a first time period, and the heating operation of the air conditioner is controlled according to a first temperature difference between the indoor temperature and a first formaldehyde removal temperature. For example, the operating frequency of the compressor in the air conditioner is determined according to the first temperature difference.

[0074] The indoor temperature of the target space is detected during the second period, and the heating operation of the air conditioner is 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. Alternatively, the compressor of the air conditioner is controlled to stop during the second period.

[0075] 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 second time period, the indoor formaldehyde concentration, outdoor ambient temperature and outdoor enthalpy value can be obtained. According to the indoor formaldehyde concentration, outdoor ambient temperature and outdoor enthalpy value, the target control mode is determined from the first control mode and the second control mode, and the air conditioner operation is controlled according to the target control mode.

[0076] A control method for an air conditioning system is proposed in an embodiment of the present invention. The method determines through state parameters that when the duration of a preset formaldehyde removal period is longer than the formaldehyde removal time required when the air conditioner is operating at a first formaldehyde removal temperature, during the ventilation process of the fresh air fan, the air conditioner is controlled to heat according to a higher first formaldehyde removal temperature during periods when outdoor thermal energy is higher, and the air conditioner is controlled to heat or shut down according to a lower second formaldehyde removal temperature during periods when 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 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, thereby meeting the formaldehyde removal requirements while reducing the energy consumption of the air conditioner.

[0077] Furthermore, in this embodiment, when the state parameter does not meet the target condition, the heating operation of the air conditioner is controlled according to the first formaldehyde removal temperature. Based on this, it can be preset that when the formaldehyde removal period is completed, the target space can achieve the target formaldehyde removal effect or the deviation from the target formaldehyde removal effect is minimal.

[0078] Furthermore, based on the above embodiments, another embodiment of the control method of the air conditioning system of the present application is proposed. In this embodiment, the first time period is a time period when the outdoor environmental parameters meet the preset conditions, and the second time period is a time period when the outdoor environmental parameters do not meet the preset conditions. The preset conditions may be a target parameter interval or a target quantity relationship or a target size relationship that the outdoor environmental parameters need to reach when the outdoor heat is greater than the target heat. The target heat is specifically the minimum heat allowed to be reached outdoors to achieve the target formaldehyde removal effect within the preset formaldehyde removal time period. Define the preset duration as the duration of the preset formaldehyde removal time period, refer to Figure 3 , before the steps of controlling the ventilation operation of the fresh air fan, controlling the heating operation of the air conditioner according to the first formaldehyde removal temperature in the first time period of the preset formaldehyde removal time period, and controlling the heating operation of the air conditioner according to the second formaldehyde removal temperature in the second time period of the preset formaldehyde removal time period or controlling the air conditioner to stop, it also includes:

[0079] Step S21, when the state parameter meets the target condition, the preset condition is determined according to the preset duration, the predicted duration and the outdoor environment data within the preset formaldehyde removal period.

[0080] 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.

[0081] 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.

[0082] Different preset durations, predicted durations, and outdoor environment data correspond to different preset conditions.

[0083] The preset conditions include critical parameter values ​​corresponding to the outdoor environment parameters, and the critical parameter values ​​can be determined according to the preset duration, the predicted duration, and the outdoor environment data, and the critical parameter values ​​can include the upper limit value and / or the lower limit value of the outdoor environment parameter. Specifically, the critical parameter value here can be calculated by substituting the preset duration, the predicted duration, and the outdoor environment data into a preset formula. Alternatively, the critical parameter value can be obtained by filtering the preset duration, the predicted duration, and the outdoor environment data according to the preset rules and then filtering from the outdoor environment data.

[0084] The preset conditions include the quantitative relationship that needs to be satisfied between the outdoor environment parameters and the preset environment parameters, and the quantitative relationship can be determined according to the preset duration, the predicted duration, and the outdoor environment data. Specifically, a preset algorithm model between the outdoor environment parameters and the preset environment parameters can be established in advance, and the quantitative relationship here can be obtained after the model parameters in the preset algorithm model are determined according to the preset duration, the predicted duration, and the outdoor environment data.

[0085] The steps of controlling the ventilation operation of the fresh air fan, controlling the heating operation of the air conditioner according to the first formaldehyde removal temperature in the first time period of the preset formaldehyde removal time period, and controlling the heating operation of the air conditioner or controlling the air conditioner to stop according to the second formaldehyde removal temperature in the second time period of the preset formaldehyde removal time period include:

[0086] Step S22, controlling the ventilation operation of the fresh air fan to obtain outdoor environmental parameters of the current period;

[0087] The outdoor environmental parameters here are specifically detected by the above-mentioned outdoor detection module.

[0088] Step S23, when the outdoor environmental parameters meet the preset conditions, controlling the air conditioner to operate in heating mode according to the first formaldehyde removal temperature;

[0089] When the outdoor environmental parameters meet the preset conditions, the indoor temperature of the target space is detected, and the heating operation of the air conditioner is 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.

[0090] Step S24, when the outdoor environmental parameters do not meet the preset conditions, the air conditioner is controlled to operate in heating mode or to be shut down according to the second formaldehyde removal temperature.

[0091] When the outdoor environmental parameters do not meet the preset conditions, the indoor temperature of the target space is detected within the second time period, and the air conditioner is controlled to operate in heating mode 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. Alternatively, when the outdoor environmental parameters do not meet the preset conditions, the compressor of the air conditioner is controlled to stop.

[0092] After step S23 or step S24, the process may return to step S10.

[0093] In this embodiment, the preset conditions for distinguishing the first time period and the second time period are determined in combination with the preset duration, the predicted duration and the outdoor environment data within the preset formaldehyde removal period, thereby ensuring the accuracy of the allocation of the first time period and the second time period within the preset formaldehyde removal period, and ensuring that the target formaldehyde removal effect can be achieved at the end of the preset formaldehyde removal period while effectively saving energy consumption.

[0094] Furthermore, in the present embodiment, the preset formaldehyde removal time period includes at least two unit time periods, and different unit time periods correspond to different preset conditions. For example, the unit time period here is one day, and each day in the preset formaldehyde removal time period corresponds to different preset conditions. The step of determining the preset condition based on the preset duration, the predicted duration, and the outdoor environmental data in the preset formaldehyde removal time period includes: determining the target formaldehyde removal duration in the unit time period based on the relationship value between the predicted duration and the preset duration; determining the preset condition corresponding to the unit time period based on the outdoor environmental data and the target formaldehyde removal duration.

[0095] In this embodiment, the relationship value is the ratio of the predicted duration to the preset duration. In other embodiments, the relationship value may also be the difference between the predicted duration and the preset duration.

[0096] The target formaldehyde removal time is specifically the shortest time required to control the operation of the air conditioner at the first formaldehyde removal temperature within a unit time period. Different relationship values ​​correspond to different target formaldehyde removal times within a unit time period. The target formaldehyde removal time can be calculated by substituting the relationship value into a preset formula, or the numerical range of the relationship value can be determined, and the target formaldehyde removal time can be determined based on the numerical range.

[0097] In this embodiment, the relationship value is a ratio, and the product of the unit time corresponding to the unit time period and the ratio is taken as the target formaldehyde removal time.

[0098] In this embodiment, the outdoor environment data includes sub-environment data corresponding to each unit time period, and the preset conditions for each unit time period are determined according to the corresponding sub-environment data and the target formaldehyde removal time. In other embodiments, the preset conditions for each unit time period can also be determined according to the corresponding sub-environment data, the target formaldehyde removal time, and the relationship between the sub-environment data.

[0099] Among them, the preset conditions can be determined before the preset formaldehyde removal period, and can also be determined within the preset formaldehyde removal period.

[0100] In this embodiment, the preset conditions are determined in the above manner to ensure that the total formaldehyde removal effect of all unit time periods can reach the target formaldehyde removal effect, and the allocation of the first time period and the second time period in each unit time period can be individually set according to the outdoor environmental data, which is beneficial to ensure that the outdoor heat in each unit time period can be effectively utilized, ensuring that the air conditioning system can meet the target formaldehyde removal effect while effectively improving the energy saving effect.

[0101] In other embodiments, the common preset conditions for all unit time periods may also be determined based on the environmental data of all unit time periods within the preset formaldehyde removal time period, and different unit time periods correspond to the same preset conditions.

[0102] Furthermore, in the present embodiment, the unit time period includes a plurality of sub-time periods, and the sum of all sub-time periods is the unit time period corresponding to the unit time period. In the present embodiment, different sub-time periods are equal, and in other embodiments, different sub-time periods may also be unequal. The outdoor environmental data includes outdoor prediction parameters corresponding to each of the sub-time periods, and the outdoor environmental data here can be obtained by acquiring weather forecast data. The step of determining the preset conditions corresponding to each of the unit time periods according to the outdoor environmental data and the target formaldehyde removal time period includes: accumulating the sub-time periods within the unit time period in order from large to small according to the outdoor heat represented by the outdoor prediction parameters, until the corresponding accumulated time period is greater than or equal to the target formaldehyde removal time period; determining the preset conditions for the corresponding unit time period according to all the outdoor prediction parameters corresponding to the accumulated time period.

[0103] Each unit time period separately accumulates the corresponding sub-duration based on the corresponding outdoor prediction parameter, and each unit time period can accumulate the corresponding accumulated duration.

[0104] In the process of duration accumulation, the outdoor prediction parameters of all sub-durations corresponding to each unit time period are arranged in order from large to small according to the outdoor heat represented. After sorting, the sub-durations corresponding to the outdoor prediction 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 target formaldehyde removal duration, the sub-durations sorted later are accumulated on the basis of the current cumulative duration to obtain a new cumulative duration, and the operation stops when the current cumulative duration is greater than or equal to the target 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 prediction parameters corresponding to all the target sub-durations corresponding to the unit time period.

[0105] In an implementation of this embodiment, the minimum temperature among all the outdoor predicted temperatures corresponding to the accumulated duration is determined as the critical temperature of the corresponding unit time period, and the preset condition includes that the outdoor ambient temperature is greater than or equal to the critical temperature.

[0106] In another implementation of this embodiment, the outdoor prediction parameters include outdoor predicted temperature, the outdoor prediction parameters include outdoor predicted enthalpy value, the minimum enthalpy value among all the outdoor predicted enthalpy values ​​corresponding to the cumulative duration is determined as the critical enthalpy value of the corresponding unit time period, and the preset condition includes that the outdoor environment enthalpy value is greater than or equal to the critical enthalpy value.

[0107] In this embodiment, through the above method, it can be ensured that the outdoor high temperature period and low temperature period can be accurately distinguished based on the corresponding preset conditions within each unit time period, and the time for the air conditioner to operate at the first formaldehyde removal temperature can accurately reach the target formaldehyde removal time required to meet the formaldehyde removal effect, and on the premise of meeting the formaldehyde removal effect, other low temperature times can be output at low energy consumption or not output, thereby effectively reducing the energy consumption of the air conditioner.

[0108] In other implementations, the critical temperature may also be determined based on the average temperature of all the predicted outdoor temperatures corresponding to the accumulated duration.

[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, before the step of determining the preset conditions corresponding to each of the unit time periods according to the outdoor environment data and the target formaldehyde removal time, it also includes: when the unit time period at the current moment is located in the starting time period within the preset formaldehyde removal time period, the target formaldehyde removal time period within the unit time period at the current moment is determined according to the relationship value between the predicted time period and the preset time period; when the unit time period at the current moment is located in the time period after the starting time period within the preset formaldehyde removal time period, the target formaldehyde removal time period within the unit time period at the current moment is determined according to the preset time period, the predicted time period, and the formaldehyde removal state parameters of the time period before the current moment within the preset formaldehyde removal time period.

[0110] The starting time period specifically refers to a preset number of unit time periods after entering the preset formaldehyde removal time period. In this embodiment, the preset number is 2.

[0111] When the current moment is in the starting time period, the unit duration of the unit time period at the current moment is corrected according to the relationship value to obtain the target formaldehyde removal duration of the current unit time period. In this embodiment, the relationship value is the ratio of the predicted duration to the preset duration, and the product of the unit duration and the ratio is used as the target formaldehyde removal duration.

[0112] In this embodiment, the formaldehyde removal status parameter is specifically any parameter that characterizes the actual formaldehyde removal situation within a preset formaldehyde removal period before the current moment, and may include but is not limited to at least one of the following parameters: formaldehyde removal time, formaldehyde concentration change value in the target space, relationship value between formaldehyde removal time corresponding to different formaldehyde removal temperatures, total time, and so on.

[0113] A quantitative relationship between the preset time, predicted time, formaldehyde removal status parameters and the target formaldehyde removal time is established in advance, and the target formaldehyde removal time can be calculated by substituting the preset time, predicted time and formaldehyde removal status parameters into the quantitative relationship.

[0114] In this embodiment, the formaldehyde removal status parameters include the total duration before the unit time period at the current moment in the preset formaldehyde removal time period and the total formaldehyde removal time within the total duration. The step of determining the target formaldehyde removal time within the unit time period at the current moment according to the preset duration, the predicted duration, and the formaldehyde removal status parameters of the time period before the current moment in the preset formaldehyde removal time period includes: determining a first difference between the preset duration and the total duration, determining a second difference between the predicted duration and the total formaldehyde removal time; and determining the target formaldehyde removal time within the unit time period at the current moment based on the relationship between the first difference and the second difference.

[0115] The total duration here can specifically be obtained by obtaining the total number of unit time periods before the current moment, and the product of the total number and the duration of the unit time period is taken as the total duration.

[0116] The total formaldehyde removal time here may be the target formaldehyde removal time corresponding to each unit period before the current moment. Alternatively, the total formaldehyde removal time may also be the time for controlling the operation of the air conditioner at the first formaldehyde removal temperature within the total time actually obtained by statistics.

[0117] In this embodiment, the relationship value is the ratio of the second difference to the first difference, and the product of the unit time period and the ratio is used as the target formaldehyde removal time. In other implementations, the relationship value may also be the difference between the first difference and the second difference.

[0118] In this embodiment, the outdoor environmental conditions in different unit time periods will be different. In particular, the longer the preset formaldehyde removal period, the greater the fluctuation in the outdoor environmental conditions will be. Dynamically adjusting the target formaldehyde removal time for each unit time period in the above manner is conducive to improving the accuracy of the preset conditions and ensuring that the actual formaldehyde removal time within the preset formaldehyde removal period can accurately reach the predicted time to meet the target formaldehyde removal effect, thereby meeting the formaldehyde removal needs while improving energy-saving effects.

[0119] 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 state parameter includes the predicted duration and the duration of the preset formaldehyde removal period, referring to Figure 4 , the steps to obtain the predicted duration include:

[0120] Step S11, obtaining the formaldehyde concentration of the target space and the ventilation operation parameters of the fresh air fan;

[0121] The formaldehyde concentration can be specifically detected by the above-mentioned formaldehyde detection module.

[0122] The ventilation operation parameters include ventilation volume, fan speed and other parameters that characterize the formaldehyde removal speed of the fresh air fan.

[0123] Step S12, determining the predicted duration according to the formaldehyde concentration, the ventilation operation parameters and the first formaldehyde removal temperature.

[0124] Different formaldehyde concentrations, ventilation operating parameters and the first formaldehyde removal temperature correspond to different prediction times.

[0125] The correspondence between formaldehyde concentration, ventilation operation parameters, first formaldehyde removal temperature and predicted duration can be preset, and the correspondence can include calculation formulas, training models, etc. Based on the correspondence, the predicted duration corresponding to the current formaldehyde concentration, ventilation operation parameters and first formaldehyde removal temperature can be determined.

[0126] The corresponding relationship here can be a preset 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 duration is obtained according to the space size parameters; the predicted duration 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.

[0127] In this embodiment, the relationship between formaldehyde concentration, ventilation operation parameters, first formaldehyde removal temperature, and space size parameters and prediction duration can be seen in the following formula: t = [(V*C*Q G ) / (V G *C G *Q)]*t G , where 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. It should be noted that the formula here is only to more intuitively show the relationship between the above parameters and the prediction duration, and is not used to limit the method for determining the prediction duration. Other forms of corresponding relationships between the parameters that meet the relationship reflected by the above formula may also be within the scope of protection of the present invention.

[0128] In this embodiment, the above method is helpful to improve the accuracy of the predicted duration, thereby further ensuring the accuracy of the air conditioner control within the preset formaldehyde removal period, so as to further ensure the formaldehyde removal effect while saving air conditioning energy efficiency.

[0129] Further, based on any of the above embodiments, the preset formaldehyde removal time includes at least two unit time periods, the first time period is a time period in which outdoor environmental parameters meet preset conditions, and the second time period is a time period in which outdoor environmental parameters do not meet the preset conditions, and different unit time periods correspond to different preset conditions. The steps of controlling the air conditioner to heat according to the first formaldehyde removal temperature in the first time period of the preset formaldehyde removal time period, and controlling the air conditioner to heat or shut down according to the second formaldehyde removal temperature in the second time period of the preset formaldehyde removal time period include: in the preset formaldehyde removal time period, when the outdoor environmental parameters of the unit time period at the current moment meet the corresponding preset conditions, controlling the air conditioner to heat according to the first formaldehyde removal temperature; when the outdoor environmental parameters of the unit time period at the current moment do not meet the corresponding preset conditions, controlling the air conditioner to heat or shut down according to the second formaldehyde removal temperature.

[0130] For example, the critical temperature corresponding to unit time period 1 is temperature 1, and the critical temperature corresponding to unit time period 2 is temperature 2. When the current moment is in unit time period 1, the outdoor ambient temperature is greater than or equal to temperature 1, then the air conditioner is controlled to heat according to the first formaldehyde removal temperature; when the current moment is in unit time period 1, the outdoor ambient temperature is less than temperature 1, then the air conditioner is controlled to heat or shut down according to the second formaldehyde removal temperature; when the current moment is in unit time period 2, the outdoor ambient temperature is greater than or equal to temperature 2, then the air conditioner is controlled to heat according to the first formaldehyde removal temperature; when the current moment is in unit time period 2, the outdoor ambient temperature is less than temperature 2, then the air conditioner is controlled to heat or shut down according to the second formaldehyde removal temperature.

[0131] In this embodiment, when the current unit period ends, the system can return to a new unit period and return to the above step S10. In this embodiment, when the current unit period does not end, the system can continue to determine whether the current outdoor environmental parameters meet the preset conditions to control the operation of the air conditioner.

[0132] In this embodiment, different unit time periods are controlled according to their respective preset conditions, thereby ensuring that each unit time period can accurately distinguish the first time period and the second time period within the time period through the corresponding preset conditions, so as to ensure the indoor formaldehyde removal effect and thus minimize the energy consumption of the air conditioner.

[0133] 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.
