Description

Technical Field

[0001] The present invention relates to the technical field of air purification, and in particular to an air purification method and device based on air conditioning. Background Art

[0002] Harmful and toxic TVOC (Total Volatile Organic Compounds) gases in the air, such as formaldehyde and benzene, can seriously affect human health. However, they cannot be filtered by the ordinary filters of existing air conditioners and are therefore absorbed by the human body. Since the air conditioner is generally closed when the room is turned on to ensure the cooling effect, this will inevitably cause harmful gases to circulate inside the indoor space for a long time. If TVOC gases accumulate to a certain concentration, such as exceeding the national limit standard, they will cause great harm to people indoors.

[0003] There are currently some air conditioners on the market that can be used to remove TVOC gases. Some use adsorption methods, while others utilize catalysts. However, TVOC removal is significantly affected by temperature, depending on the season and indoor temperature. Current products lack methods for improving TVOC removal efficiency. This suggests that existing air purification technologies based on air conditioners still have shortcomings that urgently need to be addressed. Summary of the Invention

[0094] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute a separate or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0095] The present invention discloses an air purification method and device based on air conditioning. This method can simultaneously utilize air conditioning and heating equipment within a region to deliver air and increase the temperature within the region. The temperature increase accelerates the volatilization of TVOC gases within the region, while the air delivery accelerates air flow, effectively improving the efficiency and effectiveness of the purification equipment in purifying the air within the region. This provides users with a more intelligent and efficient air purification service. Each of these is described in detail below.

[0096] Example 1

[0097] See also Figure 1 , Figure 1 This is a flow chart of an air purification method based on air conditioning disclosed in an embodiment of the present invention. Figure 1 The described method can be applied to a corresponding air purification system, wherein the air purification system may include an air conditioner, a purification device, and a heating device, wherein the air purification system may be provided with a wireless communication module and connected to the user's mobile terminal device through a cloud server to receive the air purification instruction of the user's mobile terminal device and trigger the execution of the air purification method in the embodiment of the present invention, which is not limited to the embodiment of the present invention. Figure 1As shown, the air purification method based on air conditioning may include the following operations:

[0098] 101. Determine the purification control instructions for the target area.

[0099] Specifically, the purification control command is sent to the purification equipment in the target area to activate the purification equipment to perform air purification operations. Optionally, the purification equipment can be a device with air filtration functions, such as a formaldehyde removal device. Optionally, the purification equipment can be equipped with a catalyst that can accelerate the catalysis of TVOC gases. The activity of the catalyst is greatly increased under the high temperature of the subsequent heating device. For example, the purification equipment can be equipped with a ventilation chamber, in which a catalyst and / or adsorbent material is placed to achieve the air purification function.

[0100] Optionally, the target area may be an indoor area, such as a home indoor area or a public indoor area. Preferably, the target area may be an indoor area that has just been renovated. The application of the solution of the present invention can achieve purification of toxic gases in the decoration materials of the indoor area.

[0101] 102. Determine air conditioning control instructions for the target area.

[0102] Specifically, the air conditioning control command is sent to the air conditioner in the target area to control the air output parameters of the air conditioner. Optionally, the air output parameters may include at least one of an air output mode, an air output start time, an air output end time, an air output intensity, an air output direction, and an air output position. The air output mode may be a supply air mode or a high air mode. Optionally, the air conditioning control command may be used to control specific air output devices in the air conditioner, such as fan blades, an air output motor, an air guide plate, and other specific devices, to achieve control of the aforementioned air output parameters of the air conditioner.

[0103] 103. Obtain regional temperature information of the target area, and determine whether the regional temperature information is lower than a preset temperature threshold.

[0104] Optionally, the regional temperature information of the target area can be obtained through a temperature sensor, and the temperature sensor can be integrated in the air conditioner of the target area. For example, the regional temperature information of the target area can be obtained by communicating with the air conditioner to obtain the temperature sensing parameters of its built-in temperature sensor.

[0105] Optionally, the preset temperature threshold may be an empirical value or an experimental value, and the temperature threshold is related to the minimum catalytic temperature of the target purified TVOC gas, and the minimum catalytic temperature is used to indicate the minimum temperature at which the target purified TVOC gas begins to volatilize.

[0106] 104. If the judgment result is yes, determine the heating control instruction.

[0107] Specifically, the heating control instructions are sent to the heating equipment in the target area to control the heating parameters of the heating equipment. Optionally, the heating parameters include at least one of a heating start time, a heating end time, a heating temperature, and a heating position. Optionally, the heating control instructions can be used to control specific devices within the heating equipment, such as a heating device, a hot air motor, a hot air deflector, or other specific devices, to achieve the aforementioned heating parameters of the heating equipment.

[0108] It should be noted that in the embodiment of the present invention, there is no strict order of execution between steps 101-104. They can be performed simultaneously or in other orders to achieve the best air purification effect by controlling the air conditioner, heating equipment, and purification equipment.

[0109] It can be seen that the implementation of the method described in the embodiment of the present invention can simultaneously utilize the air conditioning and heating equipment in the area to exhaust air and increase the temperature of the area, accelerate the volatilization of TVOC gas in the area by increasing the temperature, and then accelerate the flow of air by exhausting air, so as to effectively improve the efficiency and effectiveness of the purification equipment in purifying the air in the area, thereby providing users with more intelligent and efficient air purification services.

[0110] In a specific embodiment, the purification device is set at the air inlet of the air conditioner, so that the air entering the air conditioner can be purified while the air conditioner is discharging air. On the one hand, the air flow in the area is accelerated by the air conditioner's discharge, and on the other hand, a more ideal and efficient air purification effect is achieved. Furthermore, the heating device and the air conditioner can be integrated into the same device. For example, the heating device can be a PTC heater set in the air conditioner to realize the hot air / warm air delivery function of the air conditioner. An embodiment of the above-mentioned air conditioner, heating device and purification device can be referred to Figure 6 , Figure 6 An integrated air-conditioning device is shown, including an air-conditioning main body 1, a purification device 2 and a post-filter plate 3, wherein the heating device is arranged in the air-conditioning main body 1 and is not shown, and the purification device 2 is fixed at the air inlet of the air-conditioning main body 1 by the post-filter plate 3 to achieve air purification of the air entering the air conditioner.

[0111] As an optional implementation, in step 104, determining the heating control instruction includes:

[0112] The heating control instruction is determined according to the air outlet start time in the air outlet control instruction.

[0113] Specifically, the heating control instruction is used to instruct the heating device to start heating later than the air outlet start time.

[0114] It can be seen that through this optional implementation, the heating start time of the heating device can be controlled to be later than the air outlet start time of the air conditioner, so as to first increase the air flow speed in the target area through the air outlet of the air conditioner, and then increase the temperature through the heating device to accelerate the volatilization of harmful gases. On the one hand, more effective air purification can be achieved, and on the other hand, the heating time of the heating device and the heat radiation damage of the heating device to surrounding components or equipment or users can be reduced.

[0115] As an optional implementation, in step 104, determining the heating control instruction includes:

[0116] The heating control instruction is determined according to the air outlet end time in the air outlet control instruction.

[0117] Specifically, the heating control instruction is used to instruct the heating device to end heating earlier than the air outlet end time.

[0118] It can be seen that through this optional implementation, the heating end time of the heating device can be controlled to be earlier than the air outlet end time of the air conditioner, so that after a period of time after the heating device is used to increase the temperature to accelerate the volatilization of harmful gases, the air flow rate in the target area can be increased by the air outlet of the air conditioner to exhaust the air containing harmful gases. On the one hand, more effective air purification can be achieved, and on the other hand, the heating time of the heating device and the heat radiation damage of the heating device to surrounding components or equipment or users can be reduced.

[0119] As an optional embodiment, the heating control instruction is specifically used to indicate a start time difference between a heating start time and an air discharge start time of the heating device, wherein the start time difference is determined based on the following steps:

[0120] Calculate the temperature difference between the regional temperature information and the temperature threshold;

[0121] Determine the target purification time for the target area, and determine the required heating time for the target area based on the difference between the current time and the target purification time;

[0122] Determine the cooling rate of the air conditioner and the heating rate of the heating equipment;

[0123] Calculate the startup time difference according to the following formula:

[0124]

[0125] Where Δt is the start-up time difference, t 总 is the heating time requirement, ΔT is the temperature difference, V1 is the wind cooling speed, and V2 is the heating speed. The wind cooling speed is a negative number, and the heating speed is a positive number.

[0126] Optionally, the target purification time of the target area can be the required purification completion time input by the user or calculated based on the area information, or it can be the asset delivery time or asset transfer time of the target area, which is used to indicate the time point when the air quality of the target area needs to meet the standard.

[0127] Optionally, the air cooling rate of the air conditioner refers to the rate at which the air conditioner reduces the temperature of a region solely through air discharge. This rate can be calculated based on the air conditioner's historical cooling data or based on the air conditioner's operating parameters. For example, cooling data can be obtained for a first similar region similar to the target region during a first historical time period, and the air cooling rate can be determined based on the cooling rate in the cooling data during a time period identical to the current air discharge parameters of the air conditioner. The first similar region similar to the target region can be a region that is identical to the target region in at least one of the following dimensions: size, city, climate, user type, and residential type.

[0128] Optionally, the heating temperature rise rate of the heating device refers to the temperature rise rate at which the heating device raises the temperature of a region by heating. This can be calculated based on the historical temperature rise data of the heating device or based on the operating parameters of the heating device. For example, temperature rise data of a second similar region similar to the target region during a second historical time period can be obtained, and the heating temperature rise rate of the heating device can be determined based on the temperature rise rate in the temperature rise data during the same time period as the current heating parameters of the heating device. The second similar region similar to the target region can be a region that is identical to the target region in at least one of the following dimensions: size, city, climate, user type, and residence type.

[0129] It can be seen that through this optional implementation method, the start-up time difference between the heating start-up time and the air outlet start-up time of the heating device can be calculated according to the formula and relevant parameters to calculate a reasonable and effective start-up time difference. On the one hand, it can reduce the heating time of the heating device and the heat radiation damage of the heating device to surrounding components or equipment or users. On the other hand, it can still ensure more effective air purification, thereby providing users with more intelligent and efficient air purification services.

[0132] like Figure 2 As shown, the air purification method based on air conditioning may include the following operations:

[0133] 201. Obtain gas concentration parameters from multiple sensing devices in a target area.

[0134] Optionally, the gas concentration parameter is the concentration of a specific gas, which may be TVOC gas, such as formaldehyde gas. Optionally, the sensing device is a gas concentration sensing device,

[0135] 202. Calculate the product of the position weight of any sensor device and the gas concentration parameter to obtain a weighted concentration parameter.

[0136] Optionally, the sum of the position weights of all sensor devices is 1.

[0137] Optionally, the position weight is inversely proportional to the distance between the setting position of the sensing device and the center position of the target area.

[0138] Optionally, the center position is calculated based on multiple human activity trajectories in the target area. Optionally, the human activity trajectory information of the target area can be calculated first through signal data or image data. For example, multiple positioning information of multiple user devices in the target area can be obtained to determine multiple human activity trajectory information, or multiple human activity trajectories can be determined based on an image analysis algorithm and multiple image data or video data of the target area. Secondly, the center position is calculated based on multiple intersection points of the multiple human activity trajectory information. For example, the geometric center of the multiple intersection points can be calculated to obtain the center position.

[0139] 203. Calculate the sum of all weighted concentration parameters to obtain the concentration characterization parameter of the target area.

[0140] 204. Determine whether the concentration characterization parameter is greater than a preset concentration parameter threshold. If so, determine a purification control instruction for the target area.

[0141] Specifically, the purification control instruction is used to be sent to the purification equipment in the target area to start the purification equipment to perform the air purification operation.

[0153] Optionally, the color depth of each position in the concentration characterization diagram is proportional to the location device distance and the gas concentration at the position.

[0154] The location device distance is the distance between the location and the nearest sensing device, and the location gas concentration is the gas concentration parameter detected by the sensing device closest to the location.

[0166] Based on the cluster analysis algorithm, a significant region formed by multiple significant positions in the concentration representation map is determined.

[0167] Optionally, the cluster analysis algorithm may be a K-MEANS cluster analysis algorithm.

[0168] It can be seen that by implementing this optional implementation method, the significant areas within the region can be effectively determined through the color difference calculation method and cluster analysis algorithm to determine the high gas concentration areas within the region, so as to facilitate the subsequent determination of the air outlet direction of the air conditioner, achieve more targeted air conditioning outlets, accelerate the air flow in areas with high toxic gas concentrations, and provide users with more intelligent and efficient air purification services.

[0177] Optionally, the regional temperature information of the target area can be obtained through a temperature sensor, and the temperature sensor can be integrated in the air conditioner of the target area. For example, the regional temperature information of the target area can be obtained by communicating with the air conditioner to obtain the temperature sensing parameters of its built-in temperature sensor.

[0178] Optionally, the preset temperature threshold may be an empirical value or an experimental value, and the temperature threshold is related to the minimum catalytic temperature of the target purified TVOC gas, and the minimum catalytic temperature is used to indicate the minimum temperature at which the target purified TVOC gas begins to volatilize.

[0179] The heating module 304 is configured to determine a heating control instruction when the judgment result of the judgment module 303 is yes.

[0180] Specifically, the heating control instructions are sent to the heating equipment in the target area to control the heating parameters of the heating equipment. Optionally, the heating parameters include at least one of a heating start time, a heating end time, a heating temperature, and a heating position. Optionally, the heating control instructions can be used to control specific devices within the heating equipment, such as a heating device, a hot air motor, a hot air deflector, or other specific devices, to achieve the aforementioned heating parameters of the heating equipment.

[0181] It should be noted that in the embodiment of the present invention, there is no strict order of execution between steps 101-104. They can be performed simultaneously or in other orders to achieve the best air purification effect by controlling the air conditioner, heating equipment, and purification equipment.

[0182] It can be seen that the device described in the embodiment of the present invention can simultaneously utilize the air conditioning and heating equipment in the area to exhaust air and increase the temperature of the area, accelerate the volatilization of TVOC gas in the area by increasing the temperature, and then accelerate the flow of air by exhausting air, so as to effectively improve the efficiency and effectiveness of the purification equipment in purifying the air in the area, thereby providing users with more intelligent and efficient air purification services.

[0183] In a specific embodiment, the purification device is set at the air inlet of the air conditioner, so that the air entering the air conditioner can be purified while the air conditioner is discharging air. On the one hand, the air flow in the area is accelerated by the air conditioner's discharge, and on the other hand, a more ideal and efficient air purification effect is achieved. Furthermore, the heating device and the air conditioner can be integrated into the same device. For example, the heating device can be a PTC heater set in the air conditioner to realize the hot air / warm air delivery function of the air conditioner. An embodiment of the above-mentioned air conditioner, heating device and purification device can be referred to Figure 6 , Figure 6An integrated air-conditioning device is shown, including an air-conditioning main body 1, a purification device 2 and a post-filter plate 3, wherein the heating device is arranged in the air-conditioning main body 1 and is not shown, and the purification device 2 is fixed at the air inlet of the air-conditioning main body 1 by the post-filter plate 3 to achieve air purification of the air entering the air conditioner.

[0187] Calculate the sum of all weighted concentration parameters to obtain the concentration characterization parameter of the target area;

[0188] It is determined whether the concentration characterization parameter is greater than a preset concentration parameter threshold, and if so, a purification control instruction for the target area is determined.

[0189] Optionally, the sum of the position weights of all sensor devices is 1.

[0190] Optionally, the position weight is inversely proportional to the distance between the setting position of the sensing device and the center position of the target area.

[0191] Optionally, the center position is calculated based on multiple human activity trajectories in the target area. Optionally, the human activity trajectory information of the target area can be calculated first through signal data or image data. For example, multiple positioning information of multiple user devices in the target area can be obtained to determine multiple human activity trajectory information, or multiple human activity trajectories can be determined based on an image analysis algorithm and multiple image data or video data of the target area. Secondly, the center position is calculated based on multiple intersection points of the multiple human activity trajectory information. For example, the geometric center of the multiple intersection points can be calculated to obtain the center position.

[0192] By implementing this optional implementation, reasonable and representative concentration characterization parameters of the target area can be calculated based on the gas concentration parameters and position weights of multiple sensing devices, and the concentration characterization parameters can be used to determine whether the target area needs air purification, thereby accurately determining the time to start air purification, so as to effectively improve the efficiency and effectiveness of the purification equipment in purifying the air in the area, and thus provide users with more intelligent and efficient air purification services.

[0193] As an optional implementation, Figure 4 As shown, the air outlet module 302 includes:

[0194] A map generating unit 3021 is used to generate a concentration representation map of a target area based on gas concentration parameters of multiple sensing devices;

[0195] The color depth of each position in the concentration representation graph is proportional to the location device distance and the location gas concentration; the location device distance is the distance between the location and the nearest sensor device; the location gas concentration is the gas concentration parameter detected by the sensor device closest to the location;

[0196] A region analysis unit 3022 is used to determine a significant region in the concentration representation map according to a significance analysis algorithm;

[0197] A calculation unit 3023 is used to calculate a connection line between a corresponding area of ​​the salient area in the target area and the air conditioner;

[0198] The direction determination unit 3024 is used to determine the air outlet direction of the air conditioner according to the connecting line; the air outlet direction is toward the prominent area along the connecting line;

[0199] The instruction determination unit 3025 is used to determine the air conditioning control instruction of the target area according to the air outlet direction of the air conditioner.

[0200] Optionally, the air outlet direction of the air conditioner can be determined as part of the command parameters in the air conditioner control command to be transmitted to the air conditioner to control multiple specific devices of the air conditioner such as fans, fan blades, air guide plates, etc., so as to realize the air outlet of the air conditioner for the significant area.

[0201] It can be seen that by implementing this optional implementation method, a concentration characterization map can be generated first, and the significant areas in the area can be calculated through the significance analysis algorithm to determine the high gas concentration areas in the area, thereby realizing the cross-domain combination of image analysis algorithm and entity sensor parameter information, and then determining the air outlet direction of the air conditioner to achieve more targeted air conditioning outlet, accelerate the air flow in areas with high toxic gas concentrations, and effectively improve the efficiency and effectiveness of purification equipment in purifying the air in the area, thereby providing users with more intelligent and efficient air purification services.

[0202] As an optional implementation, the region analysis unit 3022 determines the specific manner of the significant region in the concentration representation map according to the significance analysis algorithm, including:

[0203] Performing a two-dimensional Fourier transform on the brightness features of the concentration representation map to obtain the significant amplitude information of the concentration representation map;

[0204] Performing logarithmic processing and low-pass filtering on the significant amplitude information to obtain redundant information of the concentration representation map;

[0205] Redundant information is removed from the concentration representation map to obtain a salient area in the concentration representation map.

[0206] It can be seen that by implementing this optional implementation method, the significant areas in the area can be effectively determined through the frequency domain transformation method to determine the high gas concentration areas in the area, so as to facilitate the subsequent determination of the air outlet direction of the air conditioner, achieve more targeted air conditioning outlets, accelerate the air flow in areas with high toxic gas concentrations, and provide users with more intelligent and efficient air purification services.

[0207] As an optional implementation, the region analysis unit 3022 determines the specific manner of the significant region in the concentration representation map according to the significance analysis algorithm, including:

[0208] Calculate the average color depth of all positions in the concentration representation map;

[0209] Calculate the color difference between the color depth of each position in the concentration representation map and the average value;

[0210] Determine whether the color difference value of any position in the concentration representation image is greater than a preset threshold, and if so, determine that position as a significant position;

[0211] Based on the cluster analysis algorithm, a significant region formed by multiple significant positions in the concentration representation map is determined.

[0212] Optionally, the cluster analysis algorithm may be a K-MEANS cluster analysis algorithm.

[0213] It can be seen that by implementing this optional implementation method, the significant areas within the region can be effectively determined through the color difference calculation method and cluster analysis algorithm to determine the high gas concentration areas within the region, so as to facilitate the subsequent determination of the air outlet direction of the air conditioner, achieve more targeted air conditioning outlets, accelerate the air flow in areas with high toxic gas concentrations, and provide users with more intelligent and efficient air purification services.

[0214] As an optional implementation, the specific manner in which the heating module 304 determines the heating control instruction includes:

[0215] The heating control instruction is determined according to the air outlet start time in the air outlet control instruction.

[0216] Specifically, the heating control instruction is used to instruct the heating device to start heating later than the air outlet start time.

[0217] It can be seen that through this optional implementation, the heating start time of the heating device can be controlled to be later than the air outlet start time of the air conditioner, so as to first increase the air flow speed in the target area through the air outlet of the air conditioner, and then increase the temperature through the heating device to accelerate the volatilization of harmful gases. On the one hand, more effective air purification can be achieved, and on the other hand, the heating time of the heating device and the heat radiation damage of the heating device to surrounding components or equipment or users can be reduced.

[0218] As an optional implementation, the specific manner in which the heating module 304 determines the heating control instruction includes:

[0219] The heating control instruction is determined according to the air outlet end time in the air outlet control instruction.

[0220] Specifically, the heating control instruction is used to instruct the heating device to end heating earlier than the air outlet end time.

[0221] It can be seen that through this optional implementation, the heating end time of the heating device can be controlled to be earlier than the air outlet end time of the air conditioner, so that after a period of time after the heating device is used to increase the temperature to accelerate the volatilization of harmful gases, the air flow rate in the target area can be increased by the air outlet of the air conditioner to exhaust the air containing harmful gases. On the one hand, more effective air purification can be achieved, and on the other hand, the heating time of the heating device and the heat radiation damage of the heating device to surrounding components or equipment or users can be reduced.

[0222] As an optional implementation, the heating control instruction is specifically used to indicate the start time difference between the heating start time and the air outlet start time of the heating device. Accordingly, Figure 4 As shown, the device further includes a time difference determining module 305, which is configured to perform the following steps to determine the startup time difference:

[0223] Calculate the temperature difference between the regional temperature information and the temperature threshold;

[0224] Determine the target purification time for the target area, and determine the required heating time for the target area based on the difference between the current time and the target purification time;

[0225] Determine the cooling rate of the air conditioner and the heating rate of the heating equipment;

[0226] Calculate the startup time difference according to the following formula:

[0227]

[0228] Where Δt is the start-up time difference, t 总 is the heating time requirement, ΔT is the temperature difference, V1 is the wind cooling speed, and V2 is the heating speed. The wind cooling speed is a negative number, and the heating speed is a positive number.

[0229] Optionally, the target purification time of the target area can be the required purification completion time input by the user or calculated based on the area information, or it can be the asset delivery time or asset transfer time of the target area, which is used to indicate the time point when the air quality of the target area needs to meet the standard.

[0230] Optionally, the air cooling rate of the air conditioner refers to the rate at which the air conditioner reduces the temperature of a region solely through air discharge. This rate can be calculated based on the air conditioner's historical cooling data or based on the air conditioner's operating parameters. For example, cooling data can be obtained for a first similar region similar to the target region during a first historical time period, and the air cooling rate can be determined based on the cooling rate in the cooling data during a time period identical to the current air discharge parameters of the air conditioner. The first similar region similar to the target region can be a region that is identical to the target region in at least one of the following dimensions: size, city, climate, user type, and residential type.

[0231] Optionally, the heating temperature rise rate of the heating device refers to the temperature rise rate at which the heating device raises the temperature of a region by heating. This can be calculated based on the historical temperature rise data of the heating device or based on the operating parameters of the heating device. For example, temperature rise data of a second similar region similar to the target region during a second historical time period can be obtained, and the heating temperature rise rate of the heating device can be determined based on the temperature rise rate in the temperature rise data during the same time period as the current heating parameters of the heating device. The second similar region similar to the target region can be a region that is identical to the target region in at least one of the following dimensions: size, city, climate, user type, and residence type.

[0232] It can be seen that through this optional implementation method, the start-up time difference between the heating start-up time and the air outlet start-up time of the heating device can be calculated according to the formula and relevant parameters to calculate a reasonable and effective start-up time difference. On the one hand, it can reduce the heating time of the heating device and the heat radiation damage of the heating device to surrounding components or equipment or users. On the other hand, it can still ensure more effective air purification, thereby providing users with more intelligent and efficient air purification services.
