[0020] Figure 1 A block diagram of an air conditioning system with a plasma generating device according to an embodiment of the present invention is exemplarily shown, the system comprising:

[0021] The air quality detection module, at the beginning of the working cycle, obtains the initial formaldehyde concentration, initial bacteria concentration and initial dust concentration at multiple locations in the target area through multiple air quality detection devices set at multiple preset locations in the target area;

[0022] The infrared detection module obtains the infrared radiation intensity at multiple positions in the target area through multiple infrared sensors arranged at multiple preset positions in the target area at multiple moments in the working cycle;

[0023] a device startup module, determining whether to start a plasma generating device in the air-conditioning system according to the initial formaldehyde concentration, the initial bacteria concentration and the initial dust concentration, wherein the plasma generating device operates at the i-th moment of the working cycle according to the working parameters determined by the working parameter model at the i-1-th moment, i≥1, and when i=1, the air-conditioning system operates according to the initial working parameters;

[0024] The continuous detection module, if it is determined to start the plasma generating device in the air conditioning system, continuously obtains the real-time formaldehyde concentration, real-time bacteria concentration, real-time dust concentration and real-time ozone concentration at multiple locations in the target area through air quality detection equipment;

[0025] A determination adjustment module determines whether it is necessary to adjust the working parameters of the air conditioning system according to the infrared radiation intensity, the real-time formaldehyde concentration, the real-time bacteria concentration, the real-time dust concentration and the real-time ozone concentration;

[0026] The parameter adjustment module determines the adjusted working parameters of the air-conditioning system according to the infrared radiation intensity, the real-time formaldehyde concentration, the real-time bacteria concentration, the real-time dust concentration and the real-time ozone concentration if the working parameters of the air-conditioning system need to be adjusted.

[0027] According to the air conditioning system with a plasma generating device in the embodiment of the present invention, the ozone concentration, formaldehyde concentration, bacteria concentration and dust concentration in the air of the target area can be accurately detected by air quality detecting equipment, and the air pollution condition of the target area can be accurately analyzed based on the air quality detecting equipment. The working parameters of the air conditioning system can be adjusted according to the air pollution condition, ozone concentration and infrared radiation intensity, thereby improving the air purification efficiency in the target area and reducing the negative impact caused by the plasma generating device.

[0028] According to one embodiment of the present invention, in the air quality detection module, at the beginning of the working cycle, the initial formaldehyde concentration, initial bacteria concentration and initial dust concentration at multiple positions in the target area are obtained by setting multiple air quality detection devices at multiple preset positions in the target area.

[0029] For example, the target area is set to a certain office space, and air quality detection equipment is set at multiple preset locations in the office space.

[0030] According to an embodiment of the present invention, in the infrared detection module, at multiple moments in a working cycle, infrared radiation intensities at multiple positions in the target area are acquired by using multiple infrared sensors disposed at multiple preset positions in the target area.

[0031] For example, infrared sensors are set at multiple preset positions in the target area. The positions and number of the infrared sensors set in the target area are the same as the positions and number of air quality detection equipment. The distribution of infrared radiation in the target area can reflect the position and range of human activities.

[0032] According to one embodiment of the present invention, in the device startup module, it is determined whether to start the plasma generating device in the air-conditioning system according to the initial formaldehyde concentration, the initial bacteria concentration and the initial dust concentration, wherein the plasma generating device operates at the i-th moment of the working cycle according to the working parameters determined by the working parameter model at the i-1-th moment, i≥1, when i=1, the air-conditioning system operates according to the initial working parameters.

[0033] For example, based on the initial formaldehyde concentration, initial bacteria concentration and initial dust concentration in the air of the target area detected by the air quality detection equipment, it is determined whether it is necessary to start the plasma generator in the air-conditioning system to purify the air in the target area. The working parameters of the air-conditioning system include: the working power of the plasma generator of the air-conditioning system, the working power of the sub-air conditioners of the air-conditioning system (such as the working power of each air outlet of the central air-conditioning in the office building).

[0034] According to one embodiment of the present invention, determining whether to start a plasma generating device in an air conditioning system according to the initial formaldehyde concentration, the initial bacteria concentration and the initial dust concentration includes:

[0035] Determining an initial formaldehyde distribution function according to the location information of the plurality of air quality detection devices and the initial formaldehyde concentration;

[0036] Determining an initial bacteria distribution function according to the location information of the plurality of air quality detection devices and the initial bacteria concentration;

[0037] Determining an initial dust distribution function according to the location information of the plurality of air quality detection devices and the initial dust concentration;

[0038] Determining the overall air pollution index at an initial moment according to the initial formaldehyde distribution function, the initial bacteria distribution function and the initial dust distribution function;

[0039] If the overall air pollution index at the initial moment is greater than the set air pollution index threshold, it is determined to start the plasma generating device in the air conditioning system.

[0040] For example, a coordinate system is established with the center of the target area as the coordinate origin, and the initial formaldehyde concentration, initial bacteria concentration, and initial dust concentration are fitted according to the position information of multiple air quality detection devices in the coordinate system, respectively, to obtain the initial formaldehyde distribution function, initial bacteria distribution function, and initial dust distribution function used to describe the formaldehyde distribution status, bacteria distribution status, and dust distribution status in the air of the target area at the initial moment of the working cycle. That is, the coordinates of any position in the target area are input into the initial formaldehyde distribution function, initial bacteria distribution function, and initial dust distribution function, and the initial formaldehyde concentration, initial bacteria concentration, and initial dust concentration at the coordinates can be obtained; according to the initial formaldehyde distribution function, initial bacteria distribution function, and initial dust distribution function, the overall air pollution index used to describe the air quality status of the target area is determined; if the overall air pollution index at the initial moment is greater than the set air pollution index threshold, it means that the overall air quality in the target area is poor, and it is determined to start the plasma generating device in the air conditioning system to purify the air in the target area.

[0041] According to one embodiment of the present invention, determining the overall air pollution index at the initial moment according to the initial formaldehyde distribution function, the initial bacteria distribution function and the initial dust distribution function comprises: determining the overall air pollution index TAp at the initial moment according to formula (1): f ,

[0042] TAP f =α1∫∫∫ Ω f f (x,y,z)dxdydz+α2∫∫∫ Ω g f (x,y,z)dxdydz+α3∫∫∫ Ω d f (x, y, z)dxdydz(1)

[0043] Among them, α1, α2 and α3 are preset weights, Ω is the range of the target area, and f f (x, y, z) is the initial formaldehyde distribution function, g f (x, y, z) is the initial bacterial distribution function, d f (x, y, z) is the initial dust distribution function, and (x, y, z) is the location information of the air quality detection equipment in the target area.

[0044] According to one embodiment of the present invention, f f (x, y, z) is the initial formaldehyde distribution function that describes the distribution of formaldehyde in the target area at the beginning of the working cycle. The initial formaldehyde distribution function is integrated within the range Ω of the target area to determine the total amount of formaldehyde in the target area ∫∫∫ Ω ff (x,y,z)dxdydz,g f (x, y, z) is the initial bacterial distribution function that describes the distribution of bacteria in the target area at the beginning of the working cycle. The initial bacterial distribution function is integrated within the range Ω of the target area to determine the total amount of bacteria in the target area ∫∫∫ Ω g f (x,y,z)dxdydz,d f (x, y, z) is the initial dust distribution function that describes the distribution of dust in the target area at the beginning of the working cycle. The initial dust distribution function is integrated within the range Ω of the target area to determine the total amount of dust in the target area ∫∫∫ Ω d f (x, y, z)dxdydz, based on the weighted sum of the total formaldehyde, total bacteria and total dust in the target area, determine the overall air pollution index at the initial time in the target area

[0045] In this way, the overall air pollution index at the initial moment can be determined based on the initial formaldehyde distribution function, the initial bacteria distribution function and the initial dust distribution function. During the calculation process, the air pollution conditions in the room can be comprehensively evaluated based on the formaldehyde content, bacteria content and dust content in the air, thereby improving the comprehensiveness and accuracy of the overall air pollution index.

[0046] According to one embodiment of the present invention, in the continuous detection module, if it is determined to start the plasma generating device in the air-conditioning system, the real-time formaldehyde concentration, real-time bacteria concentration, real-time dust concentration and real-time ozone concentration at multiple locations in the target area are continuously obtained through air quality detection equipment.

[0047] For example, after starting the plasma generator in the air-conditioning system, the real-time formaldehyde concentration, real-time bacteria concentration, real-time dust concentration and real-time ozone concentration are obtained through air quality detection equipment. The purification effect of the plasma generator is judged by detecting the real-time formaldehyde concentration, real-time bacteria concentration and real-time dust concentration in the target area. The plasma generator will produce ozone, and excessive ozone may have a certain impact on human health. The negative impact of the plasma generator can be judged by detecting the real-time ozone concentration in the target area.

[0048] According to one embodiment of the present invention, in the determination and adjustment module, it is determined whether the working parameters of the air-conditioning system need to be adjusted based on the infrared radiation intensity, the real-time formaldehyde concentration, the real-time bacteria concentration, the real-time dust concentration and the real-time ozone concentration.

[0049] According to an embodiment of the present invention, determining whether it is necessary to adjust the working parameters of the air conditioning system according to the infrared radiation intensity, the real-time formaldehyde concentration, the real-time bacteria concentration, the real-time dust concentration and the real-time ozone concentration includes:

[0050] Determine the overall air pollution index at multiple moments in a working cycle according to the real-time formaldehyde concentration, the real-time bacteria concentration and the real-time dust concentration;

[0051] Determining a real-time formaldehyde distribution function according to the location information of the plurality of air quality detection devices and the real-time formaldehyde concentration;

[0052] Determining a real-time bacteria distribution function according to the location information of the plurality of air quality detection devices and the real-time bacteria concentration;

[0053] Determining a real-time dust distribution function according to the location information of the plurality of air quality detection devices and the real-time dust concentration;

[0054] Determine the regional air pollution index at each air quality detection device according to the real-time formaldehyde distribution function, the real-time bacteria distribution function, and the real-time dust distribution function;

[0055] Determining an infrared radiation distribution function according to the position information of the plurality of infrared sensors and the infrared radiation intensity;

[0056] Determining a real-time ozone distribution function according to the location information of the plurality of air quality detection devices and the real-time ozone concentration;

[0057] Determine whether the working parameters of the air conditioning system need to be adjusted based on the overall air pollution index at multiple moments in the working cycle, the regional air pollution index at each air quality detection device, the infrared radiation distribution function and the real-time ozone distribution function.

[0058] For example, the method for obtaining the overall air pollution index at multiple moments in the working cycle is similar to the method for obtaining the overall air pollution index at the initial moment. According to the real-time formaldehyde concentration, the real-time bacteria concentration and the real-time dust concentration, the overall air pollution index of the target area at multiple moments in the working cycle is determined; according to the position information of multiple air quality detection devices in the coordinate system, the real-time formaldehyde concentration, the real-time bacteria concentration, the real-time dust concentration, the real-time ozone concentration and the infrared radiation intensity are fitted respectively to obtain the real-time formaldehyde distribution function, the real-time bacteria distribution function, the real-time dust distribution function, the real-time ozone distribution function and the infrared radiation distribution function for describing the formaldehyde distribution status, bacteria distribution status, dust distribution status, ozone distribution status and infrared radiation distribution status in the air of the target area at multiple moments in the working cycle; according to the real-time formaldehyde distribution function, the real-time bacteria distribution function and the real-time dust distribution function, the regional air pollution index for describing the pollution status of the air at each air quality detection device is determined; according to the overall air pollution index, the regional air pollution index, the infrared radiation distribution function and the real-time ozone distribution function, the air purification status of the whole and each area in the target area is judged, and it is determined whether the working parameters of the plasma generating device in the air conditioning system need to be adjusted.

[0059] According to an embodiment of the present invention, determining whether it is necessary to adjust the working parameters of the air conditioning system according to the overall air pollution index at multiple moments in the working cycle, the regional air pollution index at each air quality detection device, the infrared radiation distribution function and the real-time ozone distribution function includes: determining a first parameter adjustment condition B, a second parameter adjustment condition Z, a third parameter adjustment condition O and a fourth parameter adjustment condition R according to formula (2),

[0062] When at least one of the first parameter adjustment condition B, the second parameter adjustment condition Z, the third parameter adjustment condition O and the fourth parameter adjustment condition R is satisfied, it is determined that the operating parameters of the air-conditioning system need to be adjusted.

[0063] According to one embodiment of the present invention, in the first parameter adjustment condition B of formula (2), is the decreasing speed of the overall air pollution index in the target area at the i-th moment of the working cycle. When , it indicates that the overall air pollution cleaning speed in the target area is slow, and the overall air condition in the target area is poor, and the working parameters of the air-conditioning system need to be adjusted, for example, increasing the working power of the plasma generator in the air-conditioning system.

[0064] According to one embodiment of the present invention, in the second parameter adjustment condition Z of formula (2), RAp i，a =α1f i (x a ,y a , z a )+α2g i (x a ,y a , z a )+α3d i (x a ,y a , z a ) represents the weighted summation of the real-time formaldehyde concentration, real-time bacteria concentration and real-time dust concentration detected by the a-th air sensor at the i-th moment of the working cycle to determine the regional pollution index at the a-th air quality detection device at the i-th moment of the working cycle, RAp i-1，a =α1f i-1 (x a ,y a , z a )+α2g i-1 (x a ,y a , z a )+α3d i-1 (xa ,y a , z a ) represents the weighted summation of the real-time formaldehyde concentration, real-time bacteria concentration and real-time dust concentration detected by the a-th air sensor at the i-1-th moment of the working cycle to determine the regional pollution index at the a-th air quality detection device at the i-1-th moment of the working cycle, It represents the decreasing speed of the regional air pollution index at the ath air quality detection device in the target area at the i-th moment of the working cycle, To obtain the minimum value of the decreasing speed of the regional air pollution index at A air quality detection devices in the target area, the above-mentioned minimum value processing can be used to determine the worst case of air pollution treatment at each location in the target area. Indicates that there are locations in the target area where air pollution is being cleared more slowly. It indicates that there is a location in the target area where the air pollution cleaning speed is slow, and the air pollution in this location is serious. It is necessary to adjust the working parameters of the air-conditioning system, for example, increase the working power of the sub-air conditioner of the air-conditioning system corresponding to the location of the air quality detection equipment.

[0065] According to one embodiment of the present invention, in the third parameter adjustment condition O of formula (2), It represents the rising speed of the real-time ozone concentration at the ath air quality detection device in the target area at the i-th moment of the working cycle. Since the plasma generator will produce ozone, and when the ozone concentration is too high, it will cause harm to the human body. Therefore, when That is, when the real-time ozone concentration at the ath air quality detection device in the target area rises too fast, it is necessary to adjust the working parameters of the air-conditioning system, for example, reducing the working power of the sub-air conditioner of the air-conditioning system corresponding to the location of the air quality detection device.

[0066] According to an embodiment of the present invention, in the fourth parameter adjustment condition R of formula (2), the intensity of infrared radiation can reflect whether the degree of human activity is frequent (for example, the number of people in the room, the movement of people in the room). The greater the infrared intensity, the more frequent the human activity. When human activities are more frequent, the indoor air environment will deteriorate, and the working power of the plasma generating device of the air conditioning system needs to be increased. is the relative difference in the infrared radiation intensity collected at the ath infrared sensor at the i-th moment and the i-1-th moment of the control period, which is expressed as the relative difference in the degree of human activity at the ath infrared sensor at the i-th moment and the i-1-th moment of the control period. The larger the ratio, the greater the relative difference in the degree of human activity in two adjacent moments. When it satisfies When the condition is met, it means that the relative difference of the degree of human activity at two adjacent moments at the ath infrared sensor is greater than the preset parameter, and the working power of the sub-air conditioner of the air-conditioning system corresponding to the position needs to be adjusted.

[0067] According to one embodiment of the present invention, when at least one of the above first parameter adjustment condition B, second parameter adjustment condition Z, third parameter adjustment condition O and fourth parameter adjustment condition R is met, it is determined that the operating parameters of the air-conditioning system need to be adjusted.

[0068] In this way, it can be determined whether the working parameters of the air-conditioning system need to be adjusted based on the overall air pollution index, the regional air pollution index, the infrared radiation distribution function and the real-time ozone distribution function. When judging whether the working parameters need to be adjusted, reference is made to the relationship between the overall air pollution index, the regional pollution index and the set air pollution index threshold, the decreasing speed of the overall air pollution index and the regional pollution index, and the distribution of ozone and human activities in the target area, so as to judge whether the working parameters of the air-conditioning system are suitable for the current indoor environmental conditions. If the conditions that need to be adjusted are met, the working parameters of the air-conditioning system are adjusted, thereby improving the rationality of the working parameters of the air-conditioning system.
