[0002] Photocatalytic air purifier is a device that uses photocatalytic technology to purify the air. When light shines on the surface of the photocatalyst, the photocatalyst absorbs light energy and the formed electron-hole pairs will participate in a series of catalytic reactions. Among them, holes have strong oxidizing properties and can oxidize pollutants in the air, such as organic matter, bacteria, viruses, etc.; while electrons can reduce oxygen molecules to produce active oxygen species, such as hydroxyl radicals (·OH), thereby further decomposing organic pollutants.

[0003] Photocatalytic air purifiers generally have a built-in light source that can excite photocatalysts to produce photocatalytic reactions. Although the built-in light source excites the photocatalyst, it has a good catalytic effect, but it is accompanied by a large energy consumption. Therefore, there is an urgent need for a photocatalytic air purification solution that reduces energy consumption while ensuring the photocatalytic effect. Summary of the invention

DETAILED DESCRIPTION

[0018] The present invention is further described in detail below with reference to specific embodiments, but the embodiments of the present invention are not limited thereto.

[0019] In order to facilitate understanding of the technical solution of the present invention, the terms involved in the present invention are briefly introduced below.

[0020] 1. Formaldehyde (HCHO): It is a volatile organic compound and a common indoor air pollutant, mainly from furniture, decoration materials, etc. If the indoor formaldehyde exceeds the standard seriously, it will have a serious impact on human health.

[0021] 2. Microbial pollutants: such as bacteria, viruses and molds, etc. Mainly come from decoration building materials, human activities, air conditioning systems, heating systems, etc.

[0022] 3. Nitrogen oxides (NOx): The generation of indoor nitrogen oxides is closely related to human activities, especially from heating, cooking, smoking and other behaviors.

[0023] 4. Particulate matter (PM): refers to solid or liquid particulate matter suspended in the air. It is a pollutant that is widely present in the atmosphere. Its sources are complex and it has serious impacts on human health.

[0024] 5. Total Volatile Organic Compounds (TVOC): represents the sum of all volatile organic compounds (VOCs) in indoor air. These compounds may include alkanes, aromatic hydrocarbons, alkenes, halogenated hydrocarbons, esters, aldehydes, etc. TVOC is a comprehensive indicator used to evaluate the overall pollution level of volatile organic compounds in indoor air quality.

[0025] 6. Light intensity: referred to as illumination, it refers to the luminous flux of visible light received per unit area. It is a quantity used to indicate the intensity of light and the degree of illumination of the surface area of ​​an object. The units of light intensity are lux (abbreviated as lx) and micromoles per square meter per second (umol / m² / s). Among them, lux is the basic unit of light measurement in the International System of Units and is widely used in lighting engineering, interior design and light environment assessment.

[0026] 7. Luminous intensity: In photometry, it is referred to as light intensity or luminosity. It is a physical quantity used to represent the luminous flux of a light source per unit solid angle in a given direction. Luminous intensity is a physical quantity that describes the intensity and directionality of the light source. It represents the luminous flux (lumen Lm) emitted by a light source per unit solid angle (steradian sr) in a specific direction. The international unit of luminous intensity is candela (cd for short).

[0027] The embodiment of the present invention provides a method for adaptively adjusting light intensity and linking air purification, which can be executed by an electronic device, which can be a server or a terminal device. The server can be an independent physical server, a server cluster or a distributed system composed of multiple physical servers, or a cloud server that provides cloud computing services; the terminal device can be a smart phone, a tablet computer, a desktop computer, a wearable device, etc., but is not limited thereto. Of course, the electronic device can also be an indoor light source control device, or a photocatalytic air purifier.

[0028] Figure 1The following is a flow chart of a method for adaptively adjusting light intensity and linking air purification provided in this embodiment. Figure 1 As shown, the main process of the method is described as follows (steps S101 to S103): Step S101, obtaining current values ​​of multiple indoor air quality indicators; Step S102, if it is determined based on the current values ​​of the multiple indoor air quality indicators that the current indoor air quality does not meet the indoor air quality standard, then based on the current values ​​of the multiple indoor air quality indicators and the corresponding standard values, determine the target total light intensity of the light emitted by the catalytic light source irradiating the photocatalyst surface of the photocatalytic air purifier; wherein the catalytic light source includes an indoor light source and a built-in light source of the photocatalytic air purifier; Step S103, adjusting the luminous intensity of the indoor light source and / or the built-in light source based on the target total light intensity, so that the total energy consumption of the photocatalytic air purifier and the indoor light source is minimized when the current indoor air quality meets the indoor air quality standard.

[0029] In this embodiment, the indoor air quality index may include but is not limited to formaldehyde concentration, particulate matter concentration, microbial pollutant concentration, nitrogen oxide concentration and total volatile organic compound concentration. These concentrations can be collected in real time through corresponding sensor devices, for example, using a formaldehyde sensor to collect formaldehyde concentration, using a quartz resonator as a measuring sensitive element to collect particulate matter concentration according to a piezoelectric crystal method, using a biosensor to collect microbial pollutant concentration, using an electrochemical sensor to collect nitrogen oxide concentration, using an optical sensor to measure TVOC concentration in the air using the absorption, scattering or reflection characteristics of light, etc.

[0030] Since the catalytic light source used in this embodiment is an indoor light source and a built-in light source of a photocatalytic air purifier, if the indoor light source is to become a catalytic light source, the wavelength of the light source must be within the wavelength range suitable for the photocatalyst in order to effectively excite the photocatalyst and ensure the reaction rate.

[0031] In step S102, whether the current indoor air quality meets the indoor air quality standard can be determined based on the difference between the current value of each indoor air quality index detected and the set standard value. As long as one indoor air quality does not meet the standard, the current indoor air quality is determined to be not in compliance with the indoor air quality standard. Specifically, if the current value of any indoor air quality index is higher than the corresponding standard value, the current indoor air quality is determined to be not in compliance with the indoor air quality standard; if the current values ​​of all indoor air quality indexes are not higher than the corresponding standard values, the current indoor air quality is determined to be in compliance with the indoor air quality standard.

[0032] It should be noted that the standard values ​​of the indoor air quality indicators are different, and the size of the current value of each indoor air quality indicator is determined independently from the standard value. In addition, when determining the target total light intensity, only the indoor air quality indicators that do not meet the indoor air quality standards are considered.

[0033] In some optional embodiments, for an indoor air quality index whose current value is higher than the corresponding standard value, a target decrease rate of the indoor air quality index whose current value is higher than the corresponding standard value is determined based on the current value, the standard value and a preset duration of the indoor air quality index; and then the target total light intensity is determined based on the target decrease rate of all indoor air quality indicators whose current values ​​are higher than the corresponding standard values.

[0034] The target descent rate is obtained by first calculating the difference between the current value and the standard value, and then calculating the ratio of the difference to the preset time length.

[0035] After the target drop rate is determined, the target total light intensity can be determined in the following two situations: (1) Only one current value of the indoor air quality index is higher than the corresponding standard value; Light intensity is an important factor affecting the effect of photocatalysts. Sufficient light intensity can ensure that the photocatalyst fully absorbs light energy and undergoes chemical reactions. In photocatalytic reactions, an increase in light intensity usually leads to an increase in reaction rate. Although increasing light intensity can promote photocatalytic reactions, the degradation efficiency and light enhancement are not linearly related. When the light intensity increases to a certain level, the increase in reaction rate generally tends to be flat, because the active sites of the photocatalyst may have been saturated at this time.

[0036] Therefore, when the light intensity reaches a certain value, the decline rate of the indoor air quality index will no longer change significantly, tend to be flat, and remain approximately unchanged. This approximately unchanged decline rate is defined as the preset decline rate. If the calculated target decline rate is greater than the preset decline rate, it means that there is no suitable light intensity to achieve the target decline rate, and a segmented decline is required.

[0037] Specifically, first select at least one intermediate value between the current value and the standard value, and arrange the current value, the standard value and at least one intermediate value in descending order to form a first array; then calculate the first sub-decline rates of two adjacent values ​​in the first array in turn based on a preset time length; wherein all first sub-decline rates are not greater than the preset decline rate; then query the target total light intensity corresponding to each first sub-decline rate on the preset mapping curve in turn, and arrange the queried target total light intensities in accordance with the query order to form a second array.

[0038] The first sub-decline rate is the ratio of the difference between two adjacent values ​​in the first array to the preset duration. The second array includes at least two target total light intensities, and the luminous intensity of the catalytic light source will be adjusted according to the target light intensities in the second array.

[0039] In this embodiment, the preset mapping curve is a curve showing the decrease rate of the indoor air quality index as a function of light intensity. As the light intensity increases, the decrease rate increases accordingly, but when the light intensity increases to a certain value, the decrease rate remains almost unchanged.

[0040] It should be noted that the calculation of the target decrease rate and the first sub-decrease rate both adopts the same preset time length, which is consistent with the preset time length adopted for calculating the decrease rate of the indoor air quality index in the preset mapping curve.

[0041] (2) The current values ​​of multiple indoor air quality indicators are higher than the corresponding standard values; First, the current total light intensity of the light emitted by the catalytic light source irradiating the surface of the photocatalyst is increased by the preset light intensity to form a new current total light intensity, and the second sub-decline rate corresponding to each indoor air quality standard under the new total light intensity is queried respectively; If the second sub-decline rate of at least one indoor air quality standard is less than the corresponding target decline rate, the steps of increasing the current total light intensity of the light emitted by the catalytic light source to the surface of the photocatalyst by the preset light intensity to form a new current total light intensity, and respectively querying the second sub-decline rate corresponding to each indoor air quality standard under the new total light intensity; If the second sub-reduction rates of all indoor air quality standards are not less than the corresponding target reduction rates, the new total light intensity is determined as the target total light intensity.

[0042] The second sub-decline rate is also obtained by querying the preset mapping curve, and each indoor air quality index corresponds to a mapping curve of the decline rate of the indoor air quality index and the total light intensity.

[0043] Since the decline rates of various indoor air quality indicators under the same light intensity are not the same, the optimal light intensity required to achieve various indoor air quality indicators in line with indoor air quality standards is different. Therefore, it is necessary to set a preset light intensity to assist in finding the minimum light intensity corresponding to the compliance of various indoor air quality indicators.

[0044] In some optional embodiments, after determining the target total light intensity, the luminous intensity of the indoor light source and the photocatalytic air purifier needs to be adjusted in combination with the lowest total energy consumption value of the indoor light source and the photocatalytic air purifier. Among them, the target total light intensity and the total energy consumption value need to satisfy the following equation group: ; In the formula, is the target total light intensity; is the first target luminous intensity of the indoor light source; is the second target luminous intensity of the built-in light source; is the first light loss coefficient of the indoor light source; is the second light loss coefficient of the built-in light source; is the total energy consumption value; The first target luminous intensity of the indoor light source The corresponding first energy consumption value; Second target luminous intensity for the built-in light source The corresponding second energy consumption value.

[0045] Among them, the first light loss coefficient , the second light loss coefficient It is related to factors such as the light propagation medium, propagation distance, and propagation direction, and can be obtained through experiments.

[0046] It should be noted that the first energy consumption value , the second energy consumption value The first target luminous intensity , the second target luminous intensity Specifically, the luminous flux is calculated based on the luminous intensity, and then the light source power is calculated based on the luminous efficiency provided by the light source manufacturer, and finally the energy consumption value is determined based on the light source power and time.

[0047] In this embodiment, The lowest target is to find the appropriate first target luminous intensity and the second target luminous intensity There may be a situation where only one of the catalytic light sources is adjusted, that is, only the luminous intensity of the indoor light source is adjusted, and the luminous intensity of the built-in light source is kept unchanged, or only the luminous intensity of the built-in light source is adjusted, and the luminous intensity of the indoor light source is kept unchanged.

[0048] Based on the same inventive concept, an embodiment of the present invention provides a light intensity adaptive adjustment and air purification linkage device. Figure 2 FIG. 2 is a structural block diagram of a light intensity adaptive adjustment and air purification linkage device 200 provided in an embodiment of the present invention. Figure 2 As shown, the light intensity adaptive regulation and air purification linkage device 200 mainly includes: A current value acquisition module 201 is used to acquire current values ​​of multiple indoor air quality indicators; The light intensity determination module 202 is used to determine the target total light intensity of the light emitted by the catalytic light source irradiating the photocatalyst surface of the photocatalytic air purifier based on the current values ​​of the multiple indoor air quality indicators and the corresponding standard values ​​if the current indoor air quality does not meet the indoor air quality standard based on the current values ​​of the multiple indoor air quality indicators; wherein the catalytic light source includes the indoor light source and the built-in light source of the photocatalytic air purifier; The light intensity adjustment module 203 is used to adjust the luminous intensity of the indoor light source and / or the built-in light source based on the target total light intensity so as to minimize the total energy consumption of the photocatalytic air purifier and the indoor light source when the current indoor air quality meets the indoor air quality standard.

[0049] In some optional embodiments, the light intensity determination module 202 is specifically used to determine that the current indoor air quality does not meet the indoor air quality standard if the current value of any indoor air quality indicator is higher than the corresponding standard value; if the current values ​​of all indoor air quality indicators are not higher than the corresponding standard values, then it is determined that the current indoor air quality meets the indoor air quality standard.

[0050] In some optional embodiments, the light intensity determination module 202 includes: A first determination module is used to determine, for an indoor air quality index whose current value is higher than the corresponding standard value, a target decrease rate of the indoor air quality index whose current value is higher than the corresponding standard value based on the current value, the standard value and a preset time of the indoor air quality index; The second determination module is used to determine the target total light intensity based on the target decrease rate of the indoor air quality index whose current value is higher than the corresponding standard value.

[0051] Optionally, a second determination module is specifically used for selecting at least one intermediate value between the current value and the standard value when only one current value of the indoor air quality indicator is higher than the corresponding standard value, if the target decrease rate is greater than the preset decrease rate, and arranging the current value, the standard value and at least one intermediate value from large to small in numerical order to form a first array; calculating the first sub-decline rates of two adjacent numerical values ​​in the first array in sequence based on a preset time length; wherein all first sub-decline rates are not greater than the preset decrease rate; querying the target total light intensity corresponding to each first sub-decline rate on the preset mapping curve in sequence, and arranging the queried target total light intensities in accordance with the query order to form a second array.

[0052] Furthermore, the target descent rate is obtained by first calculating the difference between the current value and the standard value, and then calculating the ratio of the difference to the preset time length.

[0053] Optionally, the second determination module is specifically used to increase the current total light intensity of the light emitted by the catalytic light source irradiating the photocatalyst surface by a preset light intensity to form a new current total light intensity when the current values ​​of multiple indoor air quality indicators are higher than the corresponding standard values, and to query the second sub-decline rate corresponding to each indoor air quality standard under the new total light intensity respectively; if the second sub-decline rate of at least one indoor air quality standard is less than the corresponding target decline rate, continue to execute the steps of increasing the current total light intensity of the light emitted by the catalytic light source irradiating the photocatalyst surface by a preset light intensity to form a new current total light intensity, and to query the second sub-decline rate corresponding to each indoor air quality standard under the new total light intensity respectively; if the second sub-decline rates of all indoor air quality standards are not less than the corresponding target decline rates, the new total light intensity is determined as the target total light intensity.

[0054] In some optional embodiments, the target total illumination intensity and total energy consumption value satisfy the following equations: ; In the formula, is the target total light intensity; is the first target luminous intensity of the indoor light source; is the second target luminous intensity of the built-in light source; is the first light loss coefficient of the indoor light source; is the second light loss coefficient of the built-in light source; is the total energy consumption value; The first target luminous intensity of the indoor light source The corresponding first energy consumption value; Second target luminous intensity for the built-in light source The corresponding second energy consumption value.
