In this embodiment, the indoor and outdoor passage openings are windows, and the opening adjustment device 300 is a window.

[0049] Further, see Figure 1 The air conditioning system further includes an environment detection module 400, which is connected to the control device 100. The environment detection module 400 includes an indoor detection module and / or an outdoor detection module.

The monitoring device 500 includes a camera. The monitoring device 500 can be connected to a remote terminal (such as a mobile phone, a smart watch, etc.) to send monitoring data to the remote terminal.

[0051] 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.

[0052] 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.

[0053] like Figure 1 As shown, the memory 1002 as a computer storage medium may include a control program for the air conditioning system.

[0054] 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.

[0055] 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.

[0056] 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:

[0057] Step S10, controlling the ventilation operation of the fresh air fan in the target space, and detecting the first environmental parameter in the target space and / or the second environmental parameter in the outdoor environment;

[0058] The fresh air fan is controlled to switch from an off state to an on state and to perform ventilation operation. The fresh air fan is controlled to perform ventilation operation according to a preset ventilation volume, and during the ventilation operation of the fresh air fan, the first environmental parameter and / or the second environmental parameter is detected.

[0059] The first environmental parameter includes but is not limited to at least one of the following parameters: a first environmental temperature, a first environmental humidity, and a first environmental enthalpy value. The first environmental parameter is specifically detected by the indoor detection module.

[0060] The second environmental parameter includes but is not limited to at least one of the following parameters: second environmental temperature, second environmental humidity, and second environmental enthalpy value. The second environmental parameter is specifically detected by the outdoor detection module.

[0061] During the detection of the first environmental parameter and / or the second environmental parameter, the indoor and outdoor passage openings may be in a closed state or an open state.

[0062] Wherein, when the target space has a demand for indoor formaldehyde removal, step S10 may be executed.

[0063] Step S20, determining weather status information of the area where the target space is located according to the first environmental parameter and / or the second environmental parameter;

[0064] Weather status information includes but is not limited to: whether it is raining, whether it is sunny, whether it is snowing, the probability of sunny days, the probability of cloudy days, the probability of snowing days, the probability of rainy days, etc.

[0065] Different first environmental parameters and / or second environmental parameters correspond to different weather status information.

[0066] The correspondence between the first environmental parameter and / or the second environmental parameter and the weather status information may be a preset fixed relationship, which may be obtained according to actual status parameters of the air conditioning system and / or the actual status of the target space.

[0067] In one implementation, a first parameter interval in which the first environmental parameter is located and / or a second parameter interval in which the second environmental parameter is located can be determined, and weather status information can be determined based on the first parameter interval and / or the second parameter interval. For example, the preset weather associated with the first parameter interval and / or the second parameter interval is used as the weather status information.

[0068] In another implementation, the occurrence probability corresponding to each of at least two preset weathers is calculated using the first environmental parameter and / or the second environmental parameter, and the weather status information is determined based on the at least two preset weathers and the corresponding occurrence probabilities.

[0069] Step S30, controlling the operation of the fresh air fan and adjusting the opening of the indoor and outdoor passageways of the target space according to the weather status information.

[0070] Controlling the operation of the fresh air fan according to weather status information includes: controlling the fresh air fan to turn on or off or the target ventilation volume according to weather status information, etc.

[0071] Adjusting the opening of the indoor and outdoor passages of the target space according to the weather status information includes: controlling the opening or closing or the target opening of the indoor and outdoor passages according to the weather status information, etc. Specifically, the operating parameters of the opening adjustment device are determined according to the weather status information, and the opening adjustment device is controlled to operate with the operating parameters.

[0072] After step S30, the process may return to step S10.

[0073] A control method for an air conditioning system is proposed in an embodiment of the present invention. The method detects indoor and / or outdoor environmental parameters during the ventilation operation of a fresh air fan, determines weather status information based on the indoor and / or outdoor environmental parameters, controls the operation of the fresh air fan and adjusts the opening of indoor and outdoor passage openings between indoor and outdoor according to the weather status information, thereby accurately identifying the weather status of the area where the target space is located, and adapting to the weather status to control the fresh air fan and the indoor and outdoor passage openings to cooperate to achieve indoor ventilation, thereby avoiding the impact of bad weather on the indoor environment and improving the indoor ventilation effect.

[0074] Furthermore, in this embodiment, when the weather status information includes rain, the fresh air fan is controlled to operate for ventilation, and the indoor and outdoor channel openings are controlled to be closed or maintained in a closed state; when the weather status information includes no rain, the fresh air fan is controlled to stop, and the indoor and outdoor channel openings are controlled to be opened or maintained in an open state.

[0075] In this embodiment, when it rains, the indoor and outdoor passage openings are closed to prevent rain from damaging the indoor environment. At the same time, indoor ventilation is achieved by running the fresh air fan, thereby ensuring the effective balance between protecting the indoor environment and the indoor ventilation effect; when there is no rain, the indoor and outdoor vents are opened to achieve indoor ventilation and stop the fresh air fan, which can protect the indoor environment, ensure the indoor ventilation effect and save energy.

[0076] 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 predicted weather includes rain or no rain, and the predicted weather here is specifically determined according to the weather forecast. In other embodiments, the predicted weather can also be obtained by analyzing historical data.

[0077] Reference Figure 3 , the step S20 comprises:

[0078] Step S21, when the first environmental parameter and / or the second environmental parameter meets a preset condition, determining that the weather status information includes weather other than the predicted weather;

[0079] Step S22: When the first environmental parameter and / or the second environmental parameter does not satisfy the preset condition, determine that the weather status information includes the predicted weather.

[0080] The preset condition can be used to distinguish whether the actual weather is consistent with the predicted weather. The preset condition may include a target parameter interval that the first environmental parameter and / or the second environmental parameter need to reach. Alternatively, the preset condition may include a parameter interval that the characteristic value (e.g., probability of rain) calculated by the first environmental parameter and the second environmental parameter needs to reach or a target relationship that needs to be achieved between the parameter interval and the preset value.

[0081] The preset condition may be a fixed condition set in advance, or may be a condition determined according to the actual operation of the air conditioning system.

[0082] When the weather is predicted to rain, if the first environmental parameter and / or the second environmental parameter meets the preset conditions, the weather status information is determined to include no rain; if the first environmental parameter and / or the second environmental parameter does not meet the preset conditions, the weather status information is determined to include rain.

[0083] When the weather is predicted to be rainless, if the first environmental parameter and / or the second environmental parameter meets the preset conditions, it is determined that the weather status information includes rain; if the first environmental parameter and / or the second environmental parameter does not meet the preset conditions, it is determined that the weather status information includes no rain.

[0084] In this embodiment, whether there is rain in the area where the target space is located is determined by whether the first environmental parameter and / or the second environmental parameter meets the preset conditions, so as to control the fresh air fan and the indoor and outdoor channel openings to coordinate ventilation according to whether there is rain, thereby ensuring that the indoor ventilation effect is better regardless of whether it is raining and preventing rain from damaging the indoor environment.

[0085] Furthermore, in the present embodiment, the first environmental parameter includes a first environmental temperature and a second environmental temperature detected successively, and the second environmental parameter includes a first environmental humidity, and the step of determining the weather status information of the area where the target space is located according to the first environmental parameter and / or the second environmental parameter includes: determining a temperature change value according to the second environmental temperature and the first environmental temperature, and determining a humidity deviation value according to the first environmental humidity and a reference humidity corresponding to the predicted weather; when the temperature change value and the humidity deviation value meet the preset conditions, determining that the weather status information includes weather other than the predicted weather; when the temperature change value and the humidity deviation value do not meet the preset conditions, determining that the weather status information includes the predicted weather.

[0086] The first ambient temperature is greater than the second ambient temperature. The first indoor temperature data is detected during the startup phase of the fresh air fan ventilation operation, and the first ambient temperature here is determined based on the first indoor temperature data. Then, the second indoor temperature data is detected in a subsequent stage, and the second ambient temperature here is determined based on the second indoor temperature data.

[0087] The temperature change value here may be the difference obtained by subtracting the first ambient temperature from the second ambient temperature, or may be the absolute value of the difference.

[0088] The humidity deviation value here may be a difference value obtained by subtracting the reference humidity from the first ambient humidity, or may be an absolute value of the difference value.

[0089] The reference humidity is specifically the ambient humidity of the area where the target space is located in the weather forecast.

[0090] The preset conditions may include a target parameter interval that the temperature change value and / or the humidity deviation value need to reach. Alternatively, the preset conditions may include a parameter interval that the characteristic value (e.g., rain probability) calculated from the temperature change value and the humidity deviation value needs to reach or a target relationship that needs to be reached between the characteristic value and the preset value.

[0091] In this embodiment, the humidity deviation value and the temperature change value can accurately reflect the environmental status during the ventilation operation of the fresh air fan. Therefore, the humidity deviation value and the temperature change value are combined to determine whether the actual weather is consistent with the predicted weather, which is beneficial to improve the accuracy of the weather status information obtained, so as to further protect the indoor environment while improving the indoor ventilation effect.

[0092] Further, in this embodiment, the preset conditions include that the humidity deviation value is greater than or equal to a first preset threshold, and the temperature change value is greater than or equal to a second preset threshold.

[0093] The first preset threshold and the second preset threshold may be preset fixed values, or may be values ​​determined according to the actual operation of the air conditioning system. The first preset threshold and the second preset threshold may be different if the predicted weather is different.

[0094] When the weather is predicted to be rainless, the difference between the first ambient humidity and the reference humidity is the humidity deviation value, and the absolute value of the difference between the second ambient temperature and the first ambient temperature is the temperature change value.

[0095] When the weather is predicted to rain, the absolute value of the difference between the first ambient humidity and the reference humidity is the humidity deviation value, and the difference obtained by subtracting the first ambient temperature from the second ambient temperature is the temperature change value.

[0096] In this embodiment, during the fresh air ventilation process, when the indoor temperature changes greatly and the outdoor humidity deviates greatly from the predicted reference humidity, it can be considered that the actual weather is inconsistent with the predicted weather; otherwise, it can be considered that the actual weather is consistent with the predicted weather. Based on this, the accuracy of the obtained weather status information can be effectively improved, thereby further improving the accuracy of the operation control of the air conditioning system, thereby protecting the indoor environment and improving the ventilation effect.

[0097] In other embodiments, the preset condition includes that the humidity deviation value is greater than or equal to a first preset threshold or the temperature change value is greater than or equal to a second preset threshold.

[0098] Further, in this embodiment, a first preset humidity and a second preset humidity may be preset, the first preset humidity is greater than the second preset humidity, the first preset humidity is the minimum humidity allowed when there is rain in the outdoor environment, the second preset humidity is the maximum humidity allowed when there is no rain in the outdoor environment, when the outdoor humidity is greater than the first preset humidity, it can be considered that there is rain in the outdoor environment, when the outdoor humidity is less than the second preset humidity, it can be considered that there is no rain in the outdoor environment, when the outdoor humidity is between the first preset humidity and the second preset humidity, it is impossible to determine whether there is rain indoors and outdoors. Based on this, the second environmental parameter includes the second environmental humidity and the humidity change state, then:

[0099] The predicted weather includes no rain, and the preset condition includes one of the following conditions: the second ambient humidity is greater than the first preset humidity; the second ambient humidity is greater than or equal to the second preset humidity and less than or equal to the first preset humidity, and the humidity change state includes humidity increase or humidity increase amplitude greater than a preset amplitude.

[0100] The predicted weather includes rain, and the preset condition includes one of the following conditions: the second ambient humidity is less than the second preset humidity; the second ambient humidity is greater than or equal to the second preset humidity and less than or equal to the first preset humidity, and the humidity change state includes a humidity decrease or a humidity decrease greater than a preset amplitude; wherein the second preset humidity is less than the first preset humidity.

[0101] In this embodiment, the above method can accurately identify whether there is rain in the outdoor environment, thereby effectively improving the accuracy of weather status information, thereby further improving the accuracy of air conditioning system operation control, so as to protect the indoor environment while improving ventilation effects.

[0102] 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 4 , after step S20, further comprising:

[0103] Step S40, obtaining monitoring data of the area where the target space is located;

[0104] The monitoring data here is obtained by acquiring the real-time data collected by the monitoring device on the outdoor environment.

[0105] Step S50, determining a feedback result according to the monitoring data, wherein the feedback result includes accuracy information of the weather status information;

[0106] Accuracy information includes whether it is accurate and / or the accuracy value.

[0107] In this embodiment, the monitoring data is sent to the client terminal, the client terminal can output the monitoring data, and the user can return the feedback result here after seeing the monitoring data. For example, when the weather status information includes rain and the user sees rain in the monitoring data, the feedback result includes that the weather status information is accurate; when the weather status information includes rain and the user sees no rain in the monitoring data, the feedback result includes that the weather status information is wrong; when the weather status information includes no rain and the user sees rain in the monitoring data, the feedback result includes that the weather status information is wrong; when the weather status information includes rain and the user sees no rain in the monitoring data, the feedback result includes that the weather status information is accurate.

[0108] In other embodiments, it is also possible to identify whether there is a characteristic image of rain in the image of the monitoring data, and when the characteristic image is identified, determine whether the weather status information is accurate.

[0109] Step S60, modifying the preset condition according to the feedback result;

[0110] After step S30 and step S60, the process returns to step S10.

[0111] Different feedback results correspond to different correction values, and the preset conditions are corrected according to the correction values.

[0112] In one implementation, when the preset condition includes the first preset threshold and the second preset threshold, the first preset threshold and the second preset threshold are modified according to the feedback result.

[0113] In another implementation, when the preset conditions include the first preset humidity and the second preset humidity, the first preset humidity and the second preset humidity are corrected according to the feedback result.

[0114] It should be noted that the execution order of steps S40 to S60 and the above step S30 is not specifically limited.

[0115] In this embodiment, by correcting the preset conditions based on the monitoring data, self-learning training for weather condition determination can be implemented during the operation of the air conditioning system, thereby further improving the accuracy of weather condition identification, thereby further improving the accuracy of air conditioning system control, and improving ventilation effects while protecting the indoor environment.

[0116] 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 , before step S10, further comprising:

[0117] Step S01, when the forecast weather in the area where the target space is located includes rain, controlling the air conditioning system to close the indoor and outdoor passage openings;

[0118] The predicted weather including rain can be understood as the predicted weather starting to rain at a certain time point, and when the time reaches the certain time point, the air conditioning system closes the indoor and outdoor passages, and executes step S10 after step S01 is completed. Closing the indoor and outdoor vents here includes switching the indoor and outdoor vents from open to closed or maintaining the closed state.

[0119] Step S02, when the forecast weather in the area where the target space is located includes no rain, controlling the air conditioning system to open the indoor and outdoor passage openings.

[0120] The predicted weather including no rain can be understood as the predicted weather starting to stop raining at a certain time point, and when the time reaches the certain time point, the air conditioning system opens the indoor and outdoor passages, and after step S02 is completed, step S10 is executed. Here, opening the indoor and outdoor vents includes switching the indoor and outdoor vents from closed to open or maintaining an open state.

[0121] In this embodiment, the opening and closing of the indoor vents are controlled according to the predicted weather before the fresh air fan ventilation operation and environmental parameter detection. On the one hand, it is ensured that the indoor and outdoor vents can be closed in time when rain is predicted to effectively prevent rain from damaging the indoor environment. On the other hand, it is ensured that the indoor and outdoor vents are opened in time when no rain is predicted to improve the indoor ventilation effect. On the other hand, the accuracy of the actual weather represented by the environmental parameters can be improved, thereby further improving the accuracy of the weather status information, so as to further improve the indoor ventilation effect while protecting the indoor environment.

[0122] In some embodiments, the air conditioning system obtains forecast weather information at a specific time every day. When the forecast weather information is different from the weather status information determined by step S10 and step S20, the air conditioning system obtains forecast weather information for a period of time in the future of the day, and performs step S01 or step S02 according to the updated forecast weather. This embodiment can timely control the operation of the air conditioning system according to more accurate and updated forecast weather, avoiding operating the air conditioning system in a more energy-consuming manner by periodically turning on the air conditioning system.

[0123] 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.
