Description

Technical Field

[0001] This application relates to the field of air conditioning technology, and for example to a method, apparatus and air conditioning system for controlling an air conditioning system. Background Technology

[0002] Currently, the five-constant system is an independent temperature and humidity control system that maintains constant temperature, humidity, oxygen, cleanliness, and quietness throughout the entire house. This system requires sensors capable of monitoring indoor temperature, humidity, CO2 concentration, PM2.5, TVOC concentration, and formaldehyde concentration.

[0003] In related technologies, to avoid excessive costs, five constant systems typically do not use sensors with all the above functions in all individual spaces. Instead, they use simpler temperature and humidity sensors based on the different functions of each individual space.

[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0005] In related technologies, multiple temperature and humidity sensors need to be set up. The test errors between different temperature and humidity sensors will cause differences in the actual control of each individual space device, making it difficult to maintain the overall uniformity of the air condition throughout the house.

[0006] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art.

[0010] In some embodiments, the conditions for individual detection of each of the multiple spaces are met, including: the current time belongs to a preset time period, and / or, the difference in outdoor environmental parameters is greater than or equal to a set difference, and / or, when the return air box is connected to all spaces, the air parameters in the return air box do not meet the preset value.

[0011] In some embodiments, after detecting the air parameters in the return air box and obtaining the air parameters of each space, the method further includes: identifying the space whose air parameters are not within a set range as the target space; and adjusting the air parameters of the target space.

[0012] In some embodiments, air parameters include the concentration of the target gas, and / or, temperature, and / or, humidity; the air conditioning system further includes a temperature control device and a fresh air unit; adjusting the air parameters of the target space includes: if the concentration of the target gas is not within a set concentration range, controlling the fresh air unit to turn on the fresh air mode; and / or, if the temperature is not within a set temperature range, controlling the temperature control device to turn on; and / or, if the humidity is not within a set humidity range, controlling the fresh air unit to turn on the internal circulation mode.

[0013] In some embodiments, adjusting the air parameters of the target space includes: determining whether the concentration of the target gas is within a set concentration range; if the concentration of the target gas is not within the set concentration range, controlling the fresh air unit to turn on the fresh air mode; otherwise, determining whether the temperature is within a set temperature range and whether the humidity is within a set humidity range; if the temperature is not within the set temperature range, controlling the temperature regulating device to turn on; if the humidity is not within the set humidity range, controlling the fresh air unit to turn on the internal circulation mode.

[0014] In some embodiments, after adjusting the air parameters of the target space, the method further includes: opening the air valves of the target spaces one by one at first time intervals, so that the return air box is connected to each target space one by one, detecting the air parameters in the return air box, and obtaining the air parameters of each target space; if the air parameters of the target space are within the set range, then stopping the adjustment of the air parameters of the target space.

[0015] In some embodiments, after adjusting the air parameters of the target space, the method further includes: opening the air valves of the non-target spaces one by one at second intervals, so that the return air box is connected to each non-target space one by one, detecting the air parameters in the return air box, and obtaining the air parameters of each non-target space; if the air parameters of the non-target space are not within the set range, then confirming the non-target space as the target space; wherein, the first interval is shorter than the second interval.

[0016] In some embodiments, the method further includes: if the condition of individually detecting each of the multiple spaces is not met, controlling multiple air valves to open, so that the return air box is connected to the multiple spaces, and acquiring the air parameters in the return air box.

[0020] In this embodiment, the detection device is located inside the return air box. Airflow from multiple spaces can flow into the return air box through air vents. This allows the detection device inside the return air box to detect the air parameters of the airflow returning to the return air box from all spaces. When the return air box meets the conditions for individual detection of each of the multiple spaces, the air valves of each air vent are opened one by one, connecting the return air box to each space sequentially. This allows for the detection of air information returning to the return air box from each space. In this way, the air parameters of each space are detected by the device inside the return air box, improving the uniformity of whole-house equipment control and enhancing the user experience. Furthermore, this eliminates the need to install detection devices in each space, reducing construction and equipment costs.

[0037] To provide a more detailed understanding of the features and technical content of the embodiments of this disclosure, the implementation of the embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. The accompanying drawings are for illustrative purposes only and are not intended to limit the embodiments of this disclosure. In the following technical description, for ease of explanation, several details are used to provide a full understanding of the disclosed embodiments. However, one or more embodiments may still be implemented without these details. In other cases, well-known structures and devices may be simplified in their depiction to simplify the drawings.

[0038] The terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this disclosure are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate for the embodiments of this disclosure described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.

[0039] Unless otherwise stated, the term "multiple" means two or more.

[0040] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0041] The term "correspondence" can refer to an association or binding relationship. The correspondence between A and B means that there is an association or binding relationship between A and B.

[0042] Currently, the five-constant system is an independent temperature and humidity control system that maintains constant temperature, humidity, oxygen, cleanliness, and quietness throughout the entire house. This system requires sensors capable of detecting indoor temperature, humidity, CO2 concentration, PM2.5, TVOC concentration, and formaldehyde concentration. To avoid excessive cost, the five-constant system typically doesn't use sensors with all these functions in every single space. Instead, it uses simpler temperature and humidity sensors based on the different functions of each space. This requires multiple temperature and humidity sensors in multiple spaces. The testing errors between different sensors can cause differences in the actual control of each space, making it difficult to maintain the overall uniformity of the air quality throughout the house. This uniformity refers to the fact that due to the sensing errors of multiple sensors, for example, the panel may display an air conditioner temperature of x℃, while the actual temperature may be x±1℃ or x±2℃. Therefore, different users may experience deviations in their comfort temperature due to sensing errors. If different detection devices are used in different spaces, the measurement errors of these devices will lead to differences in the comfort temperature in each space, further resulting in poor uniformity.

[0043] This disclosure provides an air conditioning system that improves the uniformity of whole-house equipment control, eliminates the need for detection devices in each space, and reduces equipment layout costs.

[0044] Combination Figures 9 to 12 As shown, the air conditioning system provided in this embodiment includes an air conditioning device and a return air box 10. The air conditioning device is used to adjust the air parameters of each space 206. The return air box 10 is connected to the air conditioning device, and the airflow from each space 206 flows back to the air conditioning device through the return air box 10. The air conditioning system also includes a detection device 103, which is located inside the return air box 10. The return air box 10 has multiple air distribution ports 101 and a main air outlet 102. The multiple air distribution ports 101 can be connected to multiple spaces 206 respectively. The airflow from each space 206 flows back to the return air box 10 through the air distribution ports 101 and then flows out from the main air outlet 102. The air conditioning system also includes a detection device 103, which can detect the air parameters of the airflow from each space 206 flowing back to the return air box 10 through the air distribution ports 101, thereby detecting the air parameters of each space 206.

[0045] Optionally, the air conditioning system also includes a damper 104, each air outlet 101 is provided with a damper 104 for controlling the opening and closing of the air outlet 101.

[0046] In this embodiment, the airflow from multiple spaces 206 returns to the return air box 10 via the air distribution port 101, and then exits the return air box 10 from the main air outlet 102, thus realizing the return air function of the return air box 10. A detection device 103 is provided inside the return air box 10, which can detect the air parameters within the return air box 10. Each air distribution port 101 is equipped with an air valve 104, allowing each air distribution port 101 to be individually controlled to open and close. This allows the corresponding air valve 104 to be opened as needed to detect the air parameters of the corresponding space 206, thereby determining the air quality of each space 206 for adjustment. This eliminates the need for a separate detection device 103 for each space, enabling the detection of air parameters for a single space. Detecting the air parameters of each space 206 improves the uniformity of the air conditioning system's detection capabilities and reduces the installation cost of the detection device.

[0047] Optionally, the damper 104 is an electric damper.

[0048] Optionally, the damper 104 can be an air volume regulating valve.

[0049] Optionally, the detection device 103 can be a collection of multiple sensors. The detection device 103 can detect temperature, humidity, carbon dioxide concentration, formaldehyde concentration, or PM2.5 concentration, etc. This allows for the detection of these air parameters in each space 206. Compared to related technologies, where some spaces are only equipped with temperature and humidity sensors to save costs, the return air box 10 of this embodiment can more comprehensively detect the air quality of each space, thereby ensuring the air conditioning effect and air quality of each space 206 in all aspects, without increasing costs, and improving the user experience.

[0050] Here, "space" refers to the indoor environment, and "multiple spaces" (206) refers to multiple rooms or multiple areas within a room.

[0051] Optionally, the detection device can be a temperature sensor, humidity sensor, temperature and humidity sensor, gas sensor, etc. The gas sensor can be a carbon dioxide sensor, and / or a formaldehyde sensor, and / or a PM2.5 sensor.

[0052] Optionally, the air conditioning device can achieve comprehensive control of temperature, humidity, air quality, cleanliness and noise in the space, creating a "constant temperature, constant humidity, constant oxygen, constant cleanliness and constant quiet" environment.

[0053] Optionally, such as Figure 12As shown, the air conditioning system includes a fresh air handling unit and a temperature control unit. The fresh air handling unit maintains indoor air quality and humidity, while the temperature control unit regulates indoor temperature and humidity. Noise interference from the fresh air handling unit and temperature control unit is eliminated by employing low-noise equipment, such as fanless temperature control units and / or silent fresh air systems.

[0054] Optionally, the air conditioning unit may also include a purification device for purifying indoor air and improving air quality.

[0055] Optionally, such as Figure 9 As shown, when the air conditioning device includes a fresh air unit 20, the fresh air unit 20 has a fresh air inlet 201, a return air inlet 203 and a supply air outlet 202. The fresh air inlet 201 is connected to the outside, the return air inlet 203 is connected to the main air outlet 102, and the supply air outlet 202 is connected to each space 206. The fresh air unit 20 also includes a switching device located inside the fresh air unit 20. The switching device allows the fresh air unit 20 to switch between fresh air mode and internal circulation mode.

[0056] Optionally, when the fresh air unit 20 operates in fresh air mode, the air supply outlet 202 is connected to the fresh air inlet 201, and outdoor fresh air flows into the space 206 through the fresh air inlet 201 and the air supply outlet 202, replenishing the space 206 with fresh air. When the fresh air unit 20 operates in internal circulation mode, the air supply outlet 202 is connected to the return air inlet 203, and the airflow in the space 206 flows into the fresh air unit 20 through the return air box 10 and the return air inlet 203, and then flows out into the room from the air supply outlet 202.

[0057] Optionally, such as Figure 10 and Figure 11 As shown, the air conditioning system also includes a return air duct 207, which connects each space 206 and the air distribution port 101. An indoor return air port 205 is provided at one end of each space 206 so that the airflow of each space 206 flows back to the return air box 10 through the indoor return air port 205 and the return air duct 207.

[0058] Optionally, the fresh air unit 20 also includes an exhaust duct and an exhaust fan. One end of the exhaust duct is connected to the return air inlet 203, and the other end of the exhaust duct has an exhaust outlet 204 that connects to the outside. This allows indoor airflow to pass through the return air duct 207, return air box 10, return air inlet 203, exhaust duct, and exhaust outlet 204 to the outside. This allows for the rapid removal of stale outdoor air. The exhaust fan provides the driving force for airflow within the exhaust duct. Optionally, when the fresh air unit 20 operates in fresh air mode, the exhaust fan is turned on, allowing both fresh air intake and exhaust to begin simultaneously. This removes stale indoor air and replenishes the room with fresh air.

[0059] Optionally, the main air inlet 102 of the return air box 10 is connected to the return air inlet 203 of the fresh air unit 20. The air flowing back to the return air box 10 from each space 206 through the air distribution port 101 flows back to the fresh air unit 20 through the main air inlet 102 for internal circulation or exhaust to the outside.

[0060] Optionally, a space 206 may have one or more indoor return air vents 205. Optionally, a return air duct 207 may have one or more indoor return air vents 205.

[0061] Optionally, the indoor air supply outlet 209 can be located above the space 206 or below the space 206, or the indoor air supply outlet 209 can be provided both above and below the space 206.

[0062] Optionally, when indoor air outlets 209 are provided above and below the space 206, the air conditioning system also includes an air distribution box 210, and the air supply duct 208 includes a first air supply duct and a second air supply duct, with the first air supply duct located above the space 206 and the second air supply duct located below the space 206.

[0063] Optionally, the fresh air unit 20 also includes an air supply duct 208. One end of the air supply duct 208 is connected to the air outlet 202 of the fresh air unit 20, and the other end of the air supply duct 208 is located in the space 206 and has an indoor air outlet 209. The indoor return air outlet 205 is located above the space 206, and the indoor air outlet 209 is located below the space 206. In this way, the fresh air unit 20 has top return air and bottom air supply air, which can promote the air circulation in the space 206 and accelerate the air renewal speed.

[0064] Optionally, when the air supply duct 208 is located below the space 206, there are multiple air supply ducts 208, which extend to multiple spaces respectively. The fresh air unit also includes an air distribution box 210. The inlet of the air distribution box 210 is connected to the air outlet 202 of the fresh air unit 20, and the outlet of the air distribution box 210 is connected to multiple air supply ducts 208. The air distribution box 210 can divert the airflow from the air outlet 202 of the fresh air unit 20 to multiple air supply ducts.

[0065] Optionally, such as Figure 12 As shown, the temperature control device includes an outdoor heat pump unit and an indoor unit, the indoor unit being used to regulate the temperature of space 206; wherein, the indoor unit is located above and / or below space 206.

[0066] In this embodiment of the disclosure, the temperature regulating device regulates the temperature inside the space 206 through the outdoor heat pump unit and the indoor unit to achieve the effect of cooling or heating, and ensure the temperature stability of the space 206.

[0067] Optionally, the outdoor heat pump unit provides a cooling or heating medium to the indoor unit by driving chilled or hot water into the indoor unit. For example, when the indoor unit is located below space 206, it includes underfloor heating. When the indoor unit is located above space 206, it includes fan coil units.

[0068] Alternatively, the outdoor heat pump unit can also drive refrigerant into the indoor unit to provide cooling or heating medium for the indoor unit.

[0069] It is understood that heat pump units can be selected and configured according to needs, and this application does not impose any restrictions on this.

[0070] Optionally, the air conditioning device also includes a humidity control module 30, which is used to regulate the indoor humidity.

[0071] Optionally, such as Figure 11 and Figure 12 As shown, the humidity control module 30 is connected to the air outlet of the fresh air handling unit 20 and is used to adjust the humidity of the airflow at the air outlet of the fresh air handling unit 20. In this embodiment of the present disclosure, the air outlet of the fresh air handling unit is connected to the humidity control module 30, which can humidify or dehumidify the fresh air flowing out of the fresh air handling unit 20, thereby also adjusting the humidity of the space 206.

[0072] Optionally, the humidity control module 30 can be a humidification module or a dehumidification module.

[0073] Optionally, the air conditioning system may also include a processor for controlling the operation of the air conditioning system.

[0074] Based on the above-described air conditioning system, this disclosure also provides a method for controlling the air conditioning system. (In conjunction with...) Figure 1 As shown, the method includes:

[0075] S11. The processor determines whether the air conditioning system meets the condition of individually detecting each of the multiple spaces.

[0076] S12. Under the condition that the conditions are met, the processor opens the air valve of each air outlet one by one, so that the return air box is connected to each space one by one.

[0077] S13. With the return air box connected to each space, the processor controls the detection device to detect the air parameters inside the return air box and obtain the air parameters of each space.

[0078] Here, the detection device is located inside the return air box. This allows airflow from each space to return to the return air box through the air vents, where it is then detected by the device. This eliminates the need for a separate detection device in each space, reducing installation costs. Furthermore, since the air quality in each space is monitored by the device within the return air box, it avoids parameter errors and improves the consistency of air conditioning system adjustments. Each air vent in the return air box is equipped with a damper, allowing for sequential opening and monitoring of air parameters in the space corresponding to each vent. This enables timely detection of air parameters in each space and allows for prompt adjustment of air parameters in each space. By monitoring every space through the device within the return air box, consistency in detection is improved, the accuracy of air conditioning system adjustments is enhanced, and the user experience is improved.

[0079] Furthermore, the detection device can detect the air parameters flowing back from each space through the air vents. These air parameters can be temperature, humidity, or air quality. Air quality refers to the concentration of the target gas, which can be CO2 concentration, PM2.5, TVOC concentration, formaldehyde concentration, etc.

[0080] Optionally, when the return air box meets the condition of individually detecting each of the multiple spaces, multiple air valves operate periodically. That is, each air valve in the return air box opens one by one, and after a period of time, each air valve opens one by one again.

[0081] Optionally, the conditions for individually detecting each of the multiple spaces include: the current time belongs to a preset time period.

[0082] In this embodiment of the disclosure, the detection of each space in multiple spaces can be set according to the user's usage habits. When the air conditioning system detects that the current time belongs to a preset time period, the processor controls the return air box to open the air valve of each air outlet one by one, so that the return air box is connected to each space one by one.

[0083] Optionally, the preset time period is daytime, which can be set to 6:00 to 22:00. This way, when the air conditioning system is running during this time period, the return air box can be controlled to detect each space in multiple spaces individually.

[0084] Optionally, the preset time period is nighttime, which can be set to 10 PM to 6 AM to avoid the operation of various machines and equipment affecting users.

[0085] Optionally, during the daytime preset period, the operating cycle of each air valve in the return air box is a first preset duration. That is, during the daytime preset period, each air valve is opened and tested one by one. After each air valve has been opened once, it is opened again one by one after the first preset duration. During the nighttime preset period, the operating cycle of each air valve in the return air box is a second preset duration. That is, during the nighttime preset period, each air valve is opened and tested one by one. After each air valve has been opened once, it is opened again one by one after the second preset duration. The first preset duration is shorter than the second preset duration.

[0086] In this embodiment of the disclosure, the air conditioning system can detect each of the multiple spaces individually during both day and night. The interval between its daytime operation cycles is shorter than the interval between nighttime cycles. Since there is less user activity at night, the polling cycle can be longer at night to avoid affecting users' rest.

[0087] Optionally, the first preset duration can range from 0.5h to 2h. For example, the first preset duration can be 0.5h, 0.8h, 1h, 1.2h, 1.5h, 1.8h, or 2h, etc.

[0088] Optionally, the second preset duration can range from 2 hours to 4 hours. For example, the second preset duration can be 2 hours, 2.5 hours, 2.8 hours, 3 hours, 3.5 hours, 3.8 hours, or 4 hours, etc.

[0089] Optionally, the conditions for individually detecting each of the multiple spaces include: the difference in the change of outdoor environmental parameters is greater than or equal to a set difference.

[0090] In this embodiment of the disclosure, when the outdoor environment changes, the processor also controls the return air box to detect each of the multiple spaces individually. In this way, when fluctuations in the outdoor environment cause changes in the indoor environment, the detection device in the return air box can detect and detect them in time, so as to make timely adjustments and ensure the stability of indoor air parameters.

[0091] Alternatively, outdoor environmental parameters can be detected using temperature sensors, humidity sensors, temperature and humidity sensors, and / or gas sensors.

[0092] Optionally, the difference can be set as the difference in humidity, temperature, and / or the concentration of the target gas.

[0093] For example, when the difference is set to a temperature difference, the temperature difference is greater than or equal to 2℃. For example, the difference can be set to 2℃, 3℃, 5℃, 10℃, or 15℃, etc.

[0094] For example, when setting the difference as a humidity difference, the range of the humidity difference is 10% to 25%. For example, the difference can be set to 10%, 15%, 20%, or 25%.

[0095] Optionally, the conditions for individually detecting each of the multiple spaces include: the air parameters in the return air box do not meet the preset values ​​when the return air box is connected to all spaces.

[0096] In this embodiment of the disclosure, when multiple air vents are open, the airflow from multiple spaces flows through the air vents into the return air box. The gas in the return air box is the airflow returning from multiple spaces. When the detection device detects that the air parameters of the gas in the return air box do not meet the preset value, it indicates that the air parameters of some spaces are abnormal. The processor controls the return air box to detect each space in the multiple spaces individually, opening the air valve one by one to detect, in order to identify the spaces whose air parameters do not meet the preset value, and thus facilitate the adjustment of the spaces whose air parameters do not meet the preset value.

[0097] Optionally, the preset values ​​can be humidity preset values, temperature preset values, or target gas concentration preset values. The preset values ​​can be set according to user settings or historical records.

[0098] Optionally, the preset value can be a numerical range. For example, the preset value can be a preset temperature range. When the temperature of the air in the return air box is not within the temperature range when the return air box is connected to all spaces, it indicates that the temperature change is large. Each space in multiple spaces can be tested individually to identify the room where the temperature deviation occurs.

[0099] For example, the default value is the humidity range. When the humidity of the air in the return air box is not within the humidity range when the return air box is connected to all spaces, it indicates that the humidity is changing significantly. Each space in multiple spaces can be tested individually to identify the room where the humidity is deviating.

[0100] For example, the preset value can be the concentration range of the target gas. When the humidity of the air in the return air box is not within the humidity range when the return air box is connected to all spaces, it indicates that the humidity changes significantly. Each space in multiple spaces can be tested individually to identify the room where the humidity deviation occurs.

[0101] In some optional embodiments, when multiple spaces have different air parameters, if the air parameters in each space meet the preset range, the processor controls all spaces to connect to the return air box and records the air parameters in the return air box, using these parameters as the preset values. Then, after all spaces are connected to the return air box, if the air parameters in the return air box do not meet the preset values, it is determined that the air parameters in some spaces are abnormal. Each of the multiple spaces is then individually tested to confirm the spaces with abnormal air parameters.

[0102] In some alternative embodiments, when the air parameters set for multiple spaces are different, the processor can calculate the preset value corresponding to each air parameter by using the air parameters set for each space, and then detect the air in the return air box according to the preset value.

[0103] In some alternative embodiments, the preset value is a preset difference, that is, the difference in the change of air parameters in the return air box within a third preset time period is greater than or equal to the preset difference. This indicates that the air quality in the return air box has changed significantly and the air parameters of the space have changed significantly. The return air box can be controlled to detect each space in multiple spaces individually.

[0104] Optionally, when the preset temperature difference is a preset temperature difference value, the range of the preset temperature difference value is greater than 0.2℃. For example, the preset temperature difference value can be 0.2℃, 0.3℃, 0.4℃, or 0.5℃.

[0105] Optionally, the preset difference is a preset humidity difference value, which is greater than 10%. For example, the preset humidity difference value can be 10%, 12%, 15%, 18%, or 20%.

[0106] Optionally, the preset difference is a preset gas concentration, which can be set according to different gas types.

[0107] Combination Figure 2 As shown, this disclosure provides a method for controlling an air conditioning system, including:

[0108] S21. The processor determines whether the air conditioning system meets the condition of individually detecting each of the multiple spaces.

[0109] S22. Under the condition that the conditions are met, the processor opens the air valve of each air outlet one by one, so that the return air box is connected to each space one by one.

[0110] S23. With the return air box connected to each space, the processor controls the detection device to detect the air parameters inside the return air box and obtain the air parameters of each space.

[0111] S24. The processor confirms that the space where the air parameters are not within the set range is the target space.

[0112] S25, The processor controls the air conditioning device to adjust the air parameters of the target space.

[0113] In this embodiment, the return air box individually detects the air parameters of each of the multiple spaces, and the space whose air parameters are outside the set range is designated as the target space. Then, based on the target room and the air parameters within the target room that do not meet the set range, the air conditioning device is controlled to adjust the air parameters of the target space. Here, the air conditioning device can be a device that adjusts temperature, humidity, and / or target gas concentration, such as a fresh air unit, which can adjust the concentration and humidity of the target gas, and a temperature control device that can adjust the temperature of the space. This allows for targeted adjustment of the air parameters of the target space to ensure that the air parameters of each space meet the user's needs. This precise adjustment of the air parameters of the target space improves intelligence and the user experience.

[0114] Optionally, air parameters include the concentration of the target gas, and / or temperature, and / or humidity; the air conditioning system also includes temperature control devices and fresh air units. Here, the temperature control devices can cool or heat, regulating the temperature of each space. The fresh air units can provide fresh air to each space, reducing the concentration of the target gas.

[0115] Optionally, the target gas can be CO2, PM2.5, TVOC, and / or formaldehyde. Optionally, in step S25, adjusting the air parameters of the target space includes: if the concentration of the target gas is not within the set concentration range, the processor controls the fresh air unit to turn on the fresh air mode.

[0116] In this embodiment of the disclosure, when the concentration of the target gas in the target space is not within the set concentration range, it indicates that the gas quality of the target space is not up to standard. At this time, the fresh air unit is controlled to turn on the fresh air mode, which can replenish fresh air to the target space, exhaust stale air, and improve the gas quality of the target space.

[0117] Optionally, in step S25, adjusting the air parameters of the target space includes: if the temperature is not within the set temperature range, the processor controls the temperature regulation device to turn on.

[0118] In this embodiment of the disclosure, when the temperature of the target space does not meet the standard, the temperature is adjusted by controlling the temperature adjustment device to ensure the temperature stability within the space.

[0119] Optionally, when the temperature regulating device is cooling, if the temperature of the target space is higher than the first preset temperature, the temperature regulating device is controlled to increase the cooling capacity.

[0120] Optionally, when the temperature regulating device is heating, if the temperature of the target space is lower than the second preset temperature, the temperature regulating device is controlled to increase the heating capacity.

[0121] Optionally, in step S25, the air parameters of the target space are adjusted, including: if the humidity is not within the set humidity range, the processor controls the fresh air unit to start the internal circulation mode.

[0122] In this embodiment of the disclosure, when the humidity of the target space does not meet the standard, the fresh air unit is controlled to start internal circulation, so that outdoor air will not enter the target space and affect the humidity of the target space. The humidity of the target space is adjusted by starting internal circulation of the fresh air unit.

[0123] Optionally, the fresh air handling unit includes a refrigerant circulation system, which in turn includes a fresh air compressor. This allows the fresh air handling unit to also regulate temperature.

[0124] Optionally, when the temperature control device is operating in cooling mode, after controlling the fresh air unit to start internal circulation mode, the processor controls the fresh air compressor of the fresh air unit to increase the frequency.

[0125] In this embodiment of the disclosure, when the temperature regulating device is cooling, if the humidity is not within the set humidity range, the fresh air unit is controlled to circulate internally, so that outdoor moisture will not enter the room. The compressor of the fresh air unit increases the frequency, which can reduce the temperature of the target space and increase the dehumidification capacity.

[0126] Optionally, when the temperature control device is operating in heating mode, after controlling the fresh air unit to start internal circulation mode, the processor controls the humidity control module to increase its opening degree.

[0127] In this embodiment of the disclosure, when the temperature regulating device is heating, and the indoor humidity is low, the internal circulation of the fresh air unit is controlled. This can prevent cold air from entering the room and increase the opening of the humidity regulating module to increase the humidification capacity.

[0128] Combination Figure 3 This disclosure provides another method for controlling an air conditioning system, comprising:

[0129] S31. The processor determines whether the air conditioning system meets the condition of individually detecting each of the multiple spaces.

[0130] S32. Under the condition that the conditions are met, the processor opens the air valve of each air outlet one by one, so that the return air box is connected to each space one by one.

[0131] S33. With the return air box connected to each space, the processor controls the detection device to detect the air parameters inside the return air box and obtain the air parameters of each space.

[0132] S34. The processor confirms that the space where the air parameters are not within the set range is the target space.

[0133] S35. If the concentration of the target gas is not within the set concentration range, the processor will control the fresh air unit to turn on the fresh air mode.

[0134] S36. If the temperature is not within the set temperature range, the processor will control the temperature regulation device to turn on.

[0135] S37. If the humidity is not within the set humidity range, the processor will control the fresh air unit to start the internal circulation mode.

[0136] Here, after confirming the target space, abnormal air parameters of the target space are acquired. If the target gas concentration in the target space does not meet the set concentration range, the fresh air unit is controlled to supplement fresh air into the target space, updating the gas quality and improving the user experience. If the humidity does not meet the set range, the fresh air unit is controlled to activate internal circulation to prevent external moisture from entering the space and affecting the humidity. If the temperature does not meet the set range, the temperature regulation device is controlled to adjust the temperature of the space. In other words, the return air box detects air parameters in different spaces that do not meet the set range, and then controls the corresponding air conditioning device to adjust accordingly.

[0137] Optionally, in step S25, adjusting the air parameters of the target space includes: the processor determining whether the concentration of the target gas is within a set concentration range; if the concentration of the target gas is not within the set concentration range, the processor controls the fresh air unit to turn on the fresh air mode; otherwise, the processor determines whether the temperature is within a set temperature range and whether the humidity is within a set humidity range; if the temperature is not within the set temperature range, the processor controls the temperature regulating device to turn on; if the humidity is not within the set humidity range, the processor controls the fresh air unit to turn on the internal circulation mode.

[0138] When the concentration of the target gas is outside the set range, meaning the gas quality in the target space is substandard, the fresh air unit is activated first in fresh air mode to supply fresh air to the target space and exhaust stale air, improving indoor air quality. Once the concentration of the target gas is within the set range, meaning the gas quality in the target space meets the standards, other air parameters are adjusted. For example, if the humidity in the target space does not meet the preset humidity range, the fresh air unit is activated in internal circulation mode to prevent outdoor air from entering and affecting the humidity. The humidity in the target space is then adjusted via the air conditioning system. Similarly, if the temperature in the target space does not meet the preset temperature range, the temperature is adjusted by controlling the radiant temperature control device.

[0139] Combination Figure 4 This disclosure provides another method for controlling an air conditioning system, comprising:

[0140] S41. The processor determines whether the air conditioning system meets the condition of individually detecting each of the multiple spaces.

[0141] S42. Under the condition that the conditions are met, the processor opens the air valve of each air outlet one by one, so that the return air box is connected to each space one by one.

[0142] S43. With the return air box connected to each space, the processor controls the detection device to detect the air parameters inside the return air box and obtain the air parameters of each space.

[0143] S44. The processor confirms that the space where the air parameters are not within the set range is the target space.

[0144] S45. The processor determines whether the concentration of the target gas is within the set concentration range. If the concentration of the target gas is not within the set concentration range, the processor controls the fresh air unit to start the fresh air mode.

[0145] S46. If the concentration of the target gas is not within the set concentration range, the processor determines whether the temperature is within the set temperature range and whether the humidity is within the set humidity range.

[0146] S47. If the temperature is not within the set temperature range, the processor controls the temperature regulation device to turn on; if the humidity is not within the set humidity range, the processor controls the fresh air unit to turn on the internal circulation mode.

[0147] Here, when the concentration of the target gas is outside the set range, meaning the gas quality in the target space is substandard, the fresh air unit is activated first in fresh air mode to supply fresh air to the target space and exhaust stale air, thus improving indoor air quality. Once the concentration of the target gas is within the set range, meaning the gas quality in the target space meets the standards, other air parameters are then adjusted. If the humidity in the target space does not meet the standards, the fresh air unit is activated to recirculate the air, preventing outdoor air from entering the target space and affecting its humidity. The humidity in the target space is then regulated by the air conditioning system.

[0148] Optionally, in cooling mode, when multiple single spaces sharing a fresh air unit simultaneously experience humidity levels exceeding the set humidity range and target gas concentrations exceeding the set concentration, the treatment of the target gas concentration takes priority.

[0149] Optionally, in cooling mode, when a single space simultaneously experiences humidity levels exceeding the set humidity range and target gas concentrations exceeding the set concentration, the processing of the target gas concentration takes priority.

[0150] Optionally, in heating mode, when multiple single spaces sharing a single fresh air unit simultaneously experience humidity levels below the set humidity range and target gas concentrations exceeding the set concentration, the treatment of the target gas concentration takes priority.

[0151] Optionally, in heating mode, when the humidity of a single space is below the set humidity range and the concentration of the target gas exceeds the set concentration at the same time, the processing of the target gas concentration takes priority.

[0152] Optionally, in step S25, after the processor controls and adjusts the air parameters of the target space, the method further includes: the processor controls the air valves of the target spaces to open one by one at a first time interval, so that the return air box is connected to each target space one by one; the processor controls the detection device to detect the air parameters in the return air box; the processor obtains the air parameters of each target space; if the air parameters of the target space are within the set range, the processor controls the air conditioning device to stop adjusting the air parameters of the target space.

[0153] In this embodiment, after adjusting the air parameters of the target space begins, the air valves of each target space are opened one by one to sequentially detect the air parameters of each target space. When the air parameters of a target space are within a set range, it is confirmed that the air parameters of that target space meet the standard, and that space is no longer considered a target space. The processor then controls the cessation of adjusting the air parameters of the target space to maintain the current air parameters. This saves energy.

[0154] Optionally, the processor controls the cessation of adjusting the air parameters of the target space, including controlling the air conditioning unit to stop operating, or controlling the air conditioning unit to maintain its current parameters.

[0155] Combination Figure 5 As shown, this disclosure provides a method for controlling an air conditioning system, including:

[0156] S51. The processor determines whether the air conditioning system meets the condition of individually detecting each of the multiple spaces.

[0157] S52. Under certain conditions, the processor controls the opening of the air valves of each air outlet one by one, so that the return air box is connected to each space one by one.

[0158] S53. With the return air box connected to each space, the processor controls the detection device to detect the air parameters inside the return air box and obtain the air parameters of each space.

[0159] S54. The processor confirms that the space where the air parameters are not within the set range is the target space.

[0160] S55, the processor controls the air conditioning device to adjust the air parameters of the target space.

[0161] S56. Every first time interval, the processor controls the air valves of the target spaces to open one by one, so that the return air box is connected to each target space one by one. The processor controls the detection device to detect the air parameters in the return air box and obtain the air parameters of each target space.

[0162] S57. If the air parameters of the target space are within the set range, the processor controls the air handling device to stop adjusting the air parameters of the target space.

[0163] In this embodiment, after air conditioning is applied to the target space, the air parameters of each target space can be detected. If the air parameters of a space are detected to be within a set range, that target space is identified as a non-target space, and the air conditioning device will no longer adjust to the air parameters of the non-target space. This allows for precise control of the air conditioning device to adjust the target space. Simultaneously, by detecting the air parameters of the target space through the return air box, and stopping adjustment of the target space when the air parameters meet the set range, energy consumption is saved. Furthermore, by reducing the number of target spaces, the adjustment speed of the target spaces is increased.

[0164] Optionally, there can be one or more target spaces.

[0165] Optionally, in step S25, after the processor controls and adjusts the air parameters of the target space, the method further includes: every second time interval, the processor sequentially opens the air valves of the non-target spaces, connecting the return air box to each non-target space sequentially, detecting the air parameters in the return air box, and the processor acquiring the air parameters of each non-target space; if the air parameters of the non-target space are not within the set range, the processor confirms the non-target space as the target space; wherein, the first time interval is shorter than the second time interval.

[0166] In this embodiment, during the process of controlling the air conditioning device to adjust the target space, multiple air valves can be opened sequentially at second time intervals for non-target spaces, connecting the return air box and non-target spaces one by one, and acquiring the air parameters of each non-target space. This allows for monitoring of the air parameters of non-target spaces. When the air parameters of a non-target space are outside the set range, that non-target space is identified as the target space, and the air conditioning device is then controlled to adjust the target space. This allows for the detection of air parameters in non-target spaces to ensure air quality throughout the house. Furthermore, the first time interval is shorter than the second time interval, meaning the adjustment frequency for the target space is higher than that for non-target spaces. This prioritizes adjusting the air parameters of the target space while also considering the air quality of non-target spaces, improving the user experience.

[0167] Combination Figure 6 As shown, this disclosure provides a method for controlling an air conditioning system, including:

[0168] S61. The processor determines whether the air conditioning system meets the condition of individually detecting each of the multiple spaces.

[0169] S62. Under the condition that the conditions are met, the processor opens the air valve of each air outlet one by one, so that the return air box is connected to each space one by one.

[0170] S63. With the return air box connected to each space, the processor controls the detection device to detect the air parameters inside the return air box and obtain the air parameters of each space.

[0171] S64. The processor confirms that the space where the air parameters are not within the set range is the target space.

[0172] S65, The processor controls the air handling unit to adjust the air parameters of the target space.

[0173] S66. Every second time interval, the processor opens the air valves of the non-target spaces one by one, so that the return air box is connected to each non-target space one by one. The processor controls the detection device to detect the air parameters in the return air box and obtain the air parameters of each non-target space.

[0174] S67. If the air parameters of the non-target space are not within the set range, the processor confirms the non-target space as the target space; wherein, the first duration is less than the second duration.

[0175] Here, by individually testing each of the multiple spaces, the air parameters of each space can be measured. If a space is found to have air parameters outside the set range, that space is designated as the target space. This allows the air conditioning system to precisely adjust the air parameters for the target space. Simultaneously, the air parameters of non-target spaces are periodically measured to ensure that their parameters remain within the set range.

[0176] Optionally, when the return air box opens the air valves of the target space one by one, the air valves of the non-target spaces are all closed, and the air valves corresponding to the target spaces are opened sequentially and checked one by one.

[0177] Optionally, when the return air box opens the air valves of the target space one by one, the air valves of multiple target spaces are opened in a cycle.

[0178] Optionally, when the return air box opens the air valves of the non-target spaces one by one, the air valves of the multiple non-target spaces may be opened once or multiple times.

[0179] For example, when the processor controls the return air box to open the air valves of the target spaces one by one, the air valves corresponding to multiple target spaces open one valve every five minutes, cycling until the air parameters of one or more target spaces reach the set range. Once an air valve in a target space is identified as non-target space, it does not need to participate in the cyclical opening of the target space's air valves. Simultaneously, after the air valves in the target spaces have been open for half an hour, the processor opens the air valves of the non-target spaces one by one, while all the air valves in the target spaces remain closed. This process is repeated, opening multiple air valves in the non-target spaces for testing. After all the air valves in the non-target spaces have been opened once, the processor then controls the return air box to open the air valves of the target spaces one by one for testing.

[0180] Combination Figure 7 This disclosure provides another method for controlling an air conditioning system, comprising:

[0181] S71. The processor determines whether the air conditioning system meets the condition of individually detecting each of the multiple spaces.

[0182] S72. Under certain conditions, the processor controls the opening of the air valves of each air vent one by one, so that the return air box is connected to each space one by one.

[0183] S73. With the return air box connected to each space, the processor controls the detection device to detect the air parameters inside the return air box and obtain the air parameters of each space.

[0184] S74. If the condition of individually detecting each of the multiple spaces is not met, the processor controls multiple air valves to open, so that the return air box is connected to the multiple spaces, and obtains the air parameters in the return air box.

[0185] In this embodiment, when the air conditioning system meets the condition of individually detecting each of the multiple spaces, the return air box can detect the air parameters of each space sequentially. When the air conditioning system does not meet the condition of individually detecting each of the multiple spaces, multiple air valves in the return air box open, meaning that the airflow from multiple spaces flows into the return air box through the air distribution vents. This allows the detection device to simultaneously detect the air parameters of the airflow returning from multiple spaces, enabling unified monitoring. This reduces the operation of air valves, lowers noise, reduces energy consumption, and allows for centralized monitoring.
