[0059] Further, see Figure 2 The air conditioning system further includes a formaldehyde detection module 700 connected to the control device 100, which can be used to detect formaldehyde state parameters in the indoor space, such as formaldehyde concentration, formaldehyde content, etc.

[0060] In the embodiment of the present invention, refer to Figure 2 The control device 100 of the air conditioning system includes: a processor 1001, such as a CPU, a memory 1002, and a timer 1003.

[0061] 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.

[0062] like Figure 2 As shown, the memory 1002 as a computer storage medium may include a control program for the air conditioning system.

[0063] exist Figure 2In 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.

[0064] 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.

[0065] Reference Figure 3 , 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:

[0066] Step S10, controlling the operation of the environment adjustment device according to preset environmental parameters to detect formaldehyde status data of the target space;

[0067] The preset environmental parameters are environmental parameters when the formaldehyde release rate is optimal and measured in advance under standard working conditions. The preset environmental parameters include preset environmental temperature and / or preset environmental humidity, etc.

[0068] The preset duration may be a preset fixed value, or may be determined according to the actual state of the target space and / or user-set parameters. For example, the size parameters of the target space may be obtained and the preset duration may be determined according to the size parameters.

[0069] When the preset environmental parameters include a preset ambient temperature, the environmental conditioning device includes an air conditioner, the preset ambient temperature is used as a set temperature of the air conditioner, and the indoor temperature of the target space is heated by the air conditioner to reach the preset ambient temperature.

[0070] When the preset ambient humidity includes the preset ambient humidity, the environmental conditioning device includes a humidifier, the preset ambient humidity is used as the set humidity of the air conditioner, and the indoor humidity of the target space is humidified by the humidifier to reach the preset ambient humidity.

[0071] The operation of the environmental conditioning device is controlled according to the preset environmental parameters, and when the indoor environmental parameters reach the preset environmental parameters, the formaldehyde status data is detected. The formaldehyde status data may include formaldehyde content and / or formaldehyde content change value, etc.

[0072] During the execution of step S10, the fresh air fan is kept in a closed state.

[0073] Step S20, determining the target environmental parameters of the target space according to the formaldehyde status data;

[0074] The target environmental parameter is the target value that the environmental parameter of the target space needs to reach when the formaldehyde removal module removes formaldehyde. The target environmental parameter includes the target environmental temperature and / or the target environmental humidity.

[0075] When the air conditioning system regulates more than one target space, the target environment parameter of each target space may be determined according to the corresponding formaldehyde status data. Different target spaces may correspond to different target environment parameters.

[0076] In one implementation, the preset environmental parameters include a preset environmental temperature, and the target environmental parameters include a target environmental temperature. In another implementation, the preset environmental parameters include a preset environmental humidity, and the target environmental parameters include a target environmental humidity. In yet another implementation, the preset environmental parameters include a preset environmental humidity and a preset environmental temperature, and the target environmental parameters include a target environmental temperature and a target environmental humidity.

[0077] Different formaldehyde status data correspond to different target environmental parameters. A correspondence between the formaldehyde status parameters and the target environmental parameters is established in advance. The correspondence may include a calculation formula, a mapping relationship, an algorithm model, etc. Based on the correspondence, the target environmental parameters corresponding to the current formaldehyde status data may be determined.

[0078] In one embodiment, a relational expression between the formaldehyde status data and the target environmental parameters may be preset, and the formaldehyde status data may be substituted into the relational expression to calculate the target environmental parameters.

[0079] In another way, the correspondence between the data intervals of different formaldehyde status data and the target environmental parameters can be preset, the target data interval where the formaldehyde status data is located can be determined, and the environmental parameters corresponding to the target data interval are used as the target environmental parameters.

[0080] In another implementation, a machine learning model for predicting target environmental parameters may be established in advance, the formaldehyde status data may be input into the machine learning model, and the output result of the machine learning model may be used as the target environmental parameter.

[0081] Step S30: Controlling the operation of the environmental conditioning device according to the target environmental parameters.

[0082] The target environmental parameters are used as the setting parameters of the environmental conditioning device to control the operation of the environmental conditioning device, so that the actual environmental parameters of the target space reach the target environmental parameters.

[0083] When the target environmental parameters include a target ambient temperature, the operation of the air conditioner and / or the fresh air fan can be controlled according to the target ambient temperature.

[0084] When the target environmental parameters include target environmental humidity, the operation of the humidifier and / or the fresh air fan can be controlled according to the target environmental humidity.

[0085] In one implementation, step S10 is performed when the air conditioning system operates in the formaldehyde removal mode. In another implementation, steps S10 and S20 may be performed before the air conditioning system operates in the formaldehyde removal mode, and step S30 may be performed when the air conditioning system operates in the formaldehyde removal mode.

[0086] A control method for an air conditioning system proposed in an embodiment of the present invention, the method first controls the operation of an environmental conditioning device according to preset environmental parameters so that a target space reaches a target state of formaldehyde release, determines the target environmental parameters of the target space through formaldehyde state data detected in this process, and then controls the environmental conditioning device to adjust the indoor environment according to the target environmental parameters. In this process, the target environmental parameters when the environmental conditioning device adjusts the environment during the formaldehyde removal process are no longer pre-set fixed parameters, but can be changed according to the actual situation of indoor formaldehyde, thereby effectively improving the accuracy of the target environmental parameters, and ensuring the energy-saving effect of the environmental conditioning device. The formaldehyde release efficiency of the indoor environment after adjustment by the environmental conditioning device can be effectively improved, thereby rapidly increasing the formaldehyde removal speed of the formaldehyde removal module and achieving an effective improvement in the formaldehyde removal effect.

[0087] Furthermore, in an implementation method of the present embodiment, the target environmental parameters include a target environmental temperature and a target environmental humidity, and the step of controlling the operation of the environmental conditioning device according to the target environmental parameters includes: controlling the operation of the environmental conditioning device according to the target environmental temperature; when the temperature of the target space reaches the target environmental temperature, controlling the operation of the environmental conditioning device according to the target environmental humidity.

[0088] In this embodiment, the temperature of the target space is first adjusted to the target ambient temperature, and then the humidity of the target space is further adjusted to the target ambient humidity, which is beneficial to quickly increase the formaldehyde release rate of the target space, thereby further improving the formaldehyde removal effect.

[0089] Furthermore, in another implementation of this embodiment, the environmental conditioning device includes an air conditioner, the target environmental parameters include a target ambient temperature, and the step of controlling the operation of the environmental conditioning device according to the target environmental parameters includes: controlling the heating operation of the air conditioner according to the target ambient temperature.

[0090] The target ambient temperature is used as the set temperature to control the heating operation of the air conditioner, so that the temperature of the indoor environment can reach the target ambient temperature.

[0091] In this embodiment, the indoor ambient temperature is adjusted to the target ambient temperature through the heating regulation of the air conditioner, thereby achieving an effective improvement in the formaldehyde release efficiency of the target space.

[0092] Furthermore, in another implementation of this embodiment, the environmental conditioning device includes a humidifier, the target environmental parameters include a target environmental humidity, and the step of controlling the operation of the environmental conditioning device according to the target environmental parameters includes: controlling the operation of the humidifier according to the target environmental humidity.

[0093] The humidifier is controlled to operate with the target ambient humidity as the set humidity, thereby raising the humidity of the indoor environment to the target ambient humidity.

[0094] In this embodiment, the indoor environmental humidity is adjusted to the target environmental humidity through humidification adjustment of the humidifier, thereby achieving effective improvement of the formaldehyde release efficiency in the target space.

[0095] 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 formaldehyde status data includes the formaldehyde change parameter when the environmental parameter of the target space reaches the preset environmental parameter and the formaldehyde content value at the current moment. Figure 4 , the step S20 comprises:

[0096] Step S21, determining the target ambient temperature and / or the target ambient humidity of the target space according to the formaldehyde variation parameter and the formaldehyde content value.

[0097] When the environmental parameters of the target space reach the preset environmental parameters and maintain the preset time, the formaldehyde content can be detected at intervals of a set time to obtain at least two formaldehyde contents, and the formaldehyde change parameter is determined according to the at least two formaldehyde contents. In this embodiment, the formaldehyde change parameter is a formaldehyde change curve, which is a change characteristic of the formaldehyde content over time. In other embodiments, the formaldehyde change parameter can also be a formaldehyde change rate or a formaldehyde change amplitude.

[0098] Different formaldehyde variation parameters and different formaldehyde content values ​​may correspond to different target ambient temperatures and / or target ambient humidities.

[0099] In one implementation, a first interval in which a formaldehyde variation parameter is located is determined, a second interval of formaldehyde content values ​​is determined, and a target ambient temperature and / or a target ambient humidity is determined based on the first interval and the second interval.

[0100] In another implementation, a quantitative relationship between formaldehyde change parameters, formaldehyde content values, and target ambient temperature and / or target ambient humidity is pre-established, and the target ambient temperature and / or target ambient humidity can be calculated by substituting the formaldehyde change parameters and formaldehyde content values ​​into the quantitative relationship.

[0101] In another implementation, the deviation value between the formaldehyde change parameter and the target formaldehyde change parameter can be determined, the environmental parameter correction value can be determined according to the deviation value and the formaldehyde content value, and the preset environmental parameters can be corrected according to the environmental parameter correction value to obtain the target environmental parameters.

[0102] In this embodiment, the formaldehyde change value can accurately characterize the formaldehyde release rate during the operation of the environmental conditioning equipment controlled by preset environmental parameters, and the formaldehyde content value can accurately characterize the current formaldehyde removal demand. Therefore, the formaldehyde change value and the formaldehyde content value are combined to determine the target ambient temperature and / or target ambient humidity, thereby effectively ensuring that when the environmental conditioning equipment is controlled according to the target ambient temperature and / or target ambient humidity, the formaldehyde removal efficiency of the indoor space under the current working conditions can be closer to the optimal state, thereby effectively improving the formaldehyde release rate and effectively improving the formaldehyde removal effect.

[0103] 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. Figure 5 , the environmental conditioning device includes an air conditioner and a fresh air blower, the target environmental parameter includes a target environmental temperature, and the step of controlling the operation of the environmental conditioning device according to the target environmental parameter includes:

[0104] Step S31, obtaining the indoor temperature in the target space and the outdoor temperature outside the target space;

[0105] The indoor temperature is specifically detected by the indoor detection module, and the outdoor temperature is specifically detected by the outdoor detection module.

[0106] Step S32, controlling the ventilation operation of the fresh air fan and the heating operation of the air conditioner according to the indoor temperature, the outdoor temperature and the target ambient temperature, so that the temperature of the target space reaches the target ambient temperature.

[0107] Based on the indoor temperature, outdoor temperature and target ambient temperature, determine whether the fresh air fan ventilates the target space, the ventilation volume, whether the air conditioner is turned on for heating, the heating amount, etc.

[0108] The ventilation operation of the fresh air fan and the heating operation of the air conditioner can be started simultaneously. The ventilation volume of the fresh air fan and the heating amount of the air conditioner can be determined according to the indoor temperature, outdoor temperature and target ambient temperature. The ventilation operation of the fresh air fan can be controlled according to the ventilation volume, and the heating operation of the air conditioner can be controlled according to the heating amount.

[0109] Alternatively, it can be determined whether to turn on the fresh air fan for ventilation based on the indoor temperature, outdoor temperature and target ambient temperature, and when the fresh air fan is turned on for ventilation, the air conditioner can be controlled for heating based on the target ambient temperature, or the fresh air fan can be turned on for ventilation first, and then the air conditioner can be controlled for heating based on the target ambient temperature.

[0110] In this embodiment, the fresh air fan uses outdoor heat to assist the air conditioner in regulating the indoor temperature, thereby effectively reducing the energy consumption required for the air conditioner to adjust the indoor environment to the target ambient temperature, and the fresh air can discharge a portion of the indoor formaldehyde, thereby improving the formaldehyde removal efficiency while saving system energy consumption.

[0111] Furthermore, in the present embodiment, step S32 includes: when the outdoor temperature is greater than or equal to the indoor temperature, controlling the air conditioner to stop inputting heat to the target space, controlling the fresh air fan to start ventilation of the target space, and when a first preset condition is met, controlling the air conditioner to operate for heating according to the target ambient temperature; when the outdoor temperature is lower than the indoor temperature, controlling the fresh air fan to stop ventilation of the target space, and controlling the air conditioner to operate for heating according to the target ambient temperature.

[0112] The first preset condition specifically refers to a condition that needs to be satisfied when the air conditioning system operates when the indoor temperature state reaches a state close to the outdoor temperature state.

[0113] In this embodiment, the first preset condition includes that the indoor and outdoor temperature difference of the target space is less than or equal to the preset temperature difference value. In other embodiments, the first preset condition may also include that the duration of the fresh air fan starting to ventilate the target space is greater than or equal to the predetermined duration.

[0114] The ventilation volume of the target space when the fresh air fan is started can be a pre-set fixed value, or the ventilation volume can be determined according to the actual state of the target space. For example, the ventilation volume of the fresh air fan can be determined based on the formaldehyde concentration in the target space, the temperature difference between the indoor temperature and the outdoor temperature, the temperature difference between the indoor temperature and the target ambient temperature, and the temperature difference between the outdoor temperature and the target ambient temperature.

[0115] Specifically, the heating operation of the air conditioner can be controlled according to the temperature difference between the current ambient temperature and the target ambient temperature.

[0116] In this embodiment, when the outdoor temperature is higher than the indoor temperature, the heat of the outdoor fresh air is first used to increase the indoor ambient temperature, and then the air conditioner is used for heating, thereby effectively improving the utilization rate of the outdoor heat and effectively reducing the energy consumption of the air conditioner; when the outdoor temperature is lower than the indoor temperature, the fresh air is turned off to avoid affecting the indoor formaldehyde release efficiency, and the indoor environment is adjusted to the target ambient temperature through heating by the air conditioner alone, thereby ensuring efficient release of indoor formaldehyde to ensure the formaldehyde removal effect.

[0117] Furthermore, in the present embodiment, the air conditioner is a multi-split air conditioner, which is used to adjust the ambient temperature of at least two of the target spaces. The step of controlling the heating operation of the air conditioner according to the target ambient temperature includes: determining the heat distribution ratio between the target spaces according to at least two target ambient temperatures corresponding to at least two of the target spaces; and controlling the heating operation of the multi-split air conditioner according to the heat distribution ratio.

[0118] Specifically, the heat distribution ratio here can be determined according to the relationship value (such as ratio or difference, etc.) between different target ambient temperatures.

[0119] In this embodiment, the sum of all target ambient temperatures is determined, and the ratio of each target ambient temperature to the sum is determined as the heat distribution ratio of the corresponding target space.

[0120] The control valve in the indoor unit can be controlled to adjust the opening according to the heat distribution ratio so that the refrigerant distribution ratio matches the heat distribution ratio, thereby inputting heating amount for each target space according to the heat distribution ratio.

[0121] In this embodiment, heat is distributed according to the formaldehyde removal requirements of each target space, thereby ensuring that the formaldehyde removal effect of each target space can be effectively met, thereby further improving the energy efficiency of the system.

[0122] 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 environmental conditioning equipment includes a humidifier and a fresh air blower, and the target environmental parameter includes a target environmental humidity. Figure 6 , step S30 comprises:

[0123] Step S33, obtaining the indoor humidity in the target space and the outdoor humidity outside the target space;

[0124] The indoor humidity is specifically detected by the indoor detection module, and the outdoor humidity is specifically detected by the outdoor detection module.

[0125] Step S34, controlling the ventilation operation of the fresh air fan and the operation of the humidifier according to the indoor humidity, the outdoor humidity and the target ambient humidity, so that the humidity of the target space reaches the target humidity.

[0126] According to the indoor humidity, outdoor humidity and target ambient humidity, determine whether the fresh air fan ventilates the target space, the ventilation volume, whether the humidifier is turned on for humidification, the humidification volume, etc.

[0127] The ventilation operation of the fresh air fan and the humidification operation of the humidifier can be started simultaneously. The ventilation volume of the fresh air fan and the humidification volume of the humidifier can be determined according to the indoor humidity, outdoor humidity and target ambient humidity. The ventilation operation of the fresh air fan can be controlled according to the ventilation volume, and the humidification operation of the humidifier can be controlled according to the humidification volume.

[0128] Alternatively, whether to start the fresh air fan for ventilation operation can be determined based on the indoor humidity, outdoor humidity and target ambient humidity, and when the fresh air fan is turned on for ventilation operation, the humidifier can be controlled for humidification operation according to the target ambient humidity, or the fresh air fan can be turned on for ventilation operation first, and then the humidifier can be controlled for humidification operation according to the target ambient humidity.

[0129] In this embodiment, the fresh air fan uses outdoor humidity to assist the humidifier in adjusting the indoor humidity, thereby effectively reducing the energy consumption required for the humidifier to adjust the indoor environment to the target ambient humidity, and the fresh air can discharge a portion of the indoor formaldehyde, thereby improving the formaldehyde removal efficiency while saving system energy consumption.

[0130] Further, in the present embodiment, step S34 includes: when the outdoor humidity is greater than or equal to the indoor humidity, controlling the humidifier to stop humidifying the target space, controlling the fresh air fan to start ventilation of the target space, and when a second preset condition is met, controlling the humidifier to operate according to the target ambient humidity; when the outdoor humidity is lower than the indoor humidity, controlling the fresh air fan to stop ventilation of the target space, and controlling the humidifier to operate according to the target ambient humidity.

[0131] The second preset condition specifically refers to a condition that needs to be met for the air conditioning system to operate when the indoor humidity state reaches a state close to the outdoor humidity state.

[0132] In this embodiment, the second preset condition includes that the indoor and outdoor humidity difference of the target space is less than or equal to the preset difference. In other embodiments, the second preset condition may also include that the duration of the fresh air fan starting to ventilate the target space is greater than or equal to a predetermined duration.

[0133] The ventilation volume of the target space when the fresh air fan is started can be a pre-set fixed value, or the ventilation volume can be determined according to the actual state of the target space. For example, the ventilation volume of the fresh air fan can be determined based on the formaldehyde concentration in the target space, the temperature difference between indoor humidity and outdoor humidity, the temperature difference between indoor humidity and target ambient humidity, and the temperature difference between outdoor humidity and target ambient humidity.

[0134] Specifically, the heating operation of the humidifier can be controlled according to the temperature difference between the current ambient humidity and the target ambient humidity.

[0135] In this embodiment, when the outdoor humidity is higher than the indoor humidity, the humidity of the outdoor fresh air is first used to increase the indoor environmental humidity, and then the humidifier is used for humidification, thereby effectively improving the utilization rate of the outdoor humidity and effectively reducing the energy consumption of the humidifier; when the outdoor humidity is lower than the indoor humidity, the fresh air is turned off to avoid affecting the indoor formaldehyde release efficiency, and the indoor environment is adjusted to the target environmental humidity through humidification by the humidifier alone, thereby ensuring the efficient release of indoor formaldehyde to ensure the formaldehyde removal effect.

[0136] Furthermore, in this embodiment, the humidifier is used to adjust the ambient humidity of at least two of the target spaces, and the step of controlling the operation of the humidifier according to the target ambient humidity includes: determining the humidification distribution ratio between the target spaces according to at least two target ambient humidities corresponding to at least two of the target spaces; and controlling the operation of the humidifier according to the humidification distribution ratio.

[0137] Specifically, the humidification amount allocation ratio here can be determined according to the relationship value (such as ratio or difference, etc.) between different target ambient humidity.

[0138] In this embodiment, the sum of all target ambient temperatures is determined, and the ratio of each target ambient temperature to the sum is determined as the humidification amount allocation ratio of the corresponding target space.

[0139] According to the humidification amount distribution ratio, the flow control valve of the sub-humidification module of each target space can be controlled to adjust the opening so that the flow distribution ratio matches the humidification amount distribution ratio, thereby inputting the humidification amount for each target space according to the humidification amount distribution ratio.

[0140] In this embodiment, the humidification amount is allocated according to the formaldehyde removal demand of each target space, thereby ensuring that the formaldehyde removal effect of each target space can be effectively met, so as to further improve the energy efficiency of the system.

[0141] Further, based on the above embodiment, the target environmental parameters include the target environmental temperature and the target environmental humidity, and the environmental conditioning equipment includes an air conditioner, a fresh air blower, and a humidifier. Then, in the process of controlling the operation of the environmental conditioning equipment according to the target environmental temperature, the above steps S31 to S32 and their related detailed implementation methods can be performed, and in the process of controlling the operation of the environmental conditioning equipment according to the target environmental humidity, the above steps S33 to S34 and their related detailed implementation methods can be performed. Specifically, step S31 and step S32 are performed first, and when the ambient temperature of the target space reaches the target ambient temperature, step S33 and step S34 are performed.

[0142] Furthermore, during the execution of step S30, the formaldehyde concentration is detected. When the formaldehyde concentration is greater than a preset concentration, the fresh air fan can be controlled to start ventilation operation.

[0143] 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.
