[0053] Certain terms used to describe the present application are discussed below or elsewhere in this specification to provide additional guidance to those skilled in the art regarding the description of the present application.

[0054] Traditional indoor environmental control methods mainly focus on a single physical environmental indicator, such as temperature, humidity, light intensity or air circulation, and usually adopt either passive measures or active measures for regulation. Passive measures include natural ventilation, shading design, etc. These methods rely on the structural design of the building itself and the external environmental conditions and have the advantage of energy saving; while active measures involve the application of air conditioning systems, fresh air systems and artificial lighting systems, which can provide more precise environmental parameter control, but are often accompanied by higher energy consumption.

[0055] However, current control strategies have certain limitations. On the one hand, they often ignore the intrinsic connection between different environmental indicators, that is, the interaction between various factors may have a significant impact on the overall indoor environmental quality. On the other hand, most existing control methods consider the effect of a certain type of control measure in isolation, lacking a method to organically combine passive and active measures to achieve synergistic effects. This leads to the problem of incoordination between different control systems even in the same building environment, which in turn affects the final indoor environmental quality.

[0056] Therefore, while pursuing an efficient, comfortable and healthy indoor environment, how to integrate multiple control methods and establish a comprehensive control system that can fully consider the correlation between various environmental factors has become a key challenge facing modern building environmental science. Developing such a comprehensive control method can not only improve the quality of life and work efficiency of people in the building, but also achieve the goal of energy conservation and emission reduction while ensuring a good indoor environment, thereby promoting sustainable development.

[0057] The following is a detailed description of the indoor environment comprehensive control method provided by the embodiment of the present application in conjunction with the accompanying drawings. Figure 1 and Figure 2 As shown, the method comprises the following steps:

[0058] S1. Conduct a subjective and objective comprehensive weight analysis on the indoor environmental indicators that do not meet the indoor environmental judgment standards, and take the indoor environmental indicators with the highest comprehensive weight as the optimization object.

[0059] S2. Determine passive optimization measures for the optimization object.

[0060] S3. When the collected outdoor environmental indicators meet the outdoor environmental judgment criteria, active optimization measures are adopted.

[0061] In the above step S1, a subjective and objective comprehensive weight analysis is performed on the indoor environmental indicators that do not meet the indoor environmental judgment criteria, and the indoor environmental indicator with the highest comprehensive weight is used as the optimization object, specifically including:

[0062] S11. Collect indoor environmental indicators.

[0063] S12. According to the collected indoor environmental indicators, determine whether the indoor light, heat and humidity, and air environments meet the indoor environmental judgment criteria.

[0064] S13. When one or several indoor environmental indicators are not within the range of the indoor environmental judgment criteria, a subjective and objective comprehensive weight analysis is performed on the indoor environmental indicators using the analytic hierarchy process and the rate of change method, and the indoor environmental indicator with the highest comprehensive weight is determined and used as the optimization object.

[0065] In the embodiment of the present application, the indoor environmental indicators include light environment indicators, heat and humidity environment indicators, and air environment indicators. Specifically, the light environment indicators include work surface illuminance and physiological equivalent illuminance, the heat and humidity environment indicators include APMV, and the air environment indicators include CO2 concentration and PM2.5 concentration.

[0066] The indoor environmental judgment criteria include light environment indicators, heat and humidity environment indicators, and air environment indicators. Among them, the light environment indicators include: the work surface illuminance is preferably 450 lx to 2000 lx, and the physiological equivalent illuminance in the morning in light climate zones I to IV and throughout the day in light climate zone V is ≥ 250 lx. The heat and humidity environment indicators include: the suitable value of APMV (Adaptive Predicted Mean Vote) is -0.5 to +0.5. The air environment indicators include: the CO2 concentration ≤ 0.10%, and the PM 2.5 concentration ≤ 0.05 mg / m 3 .

[0067] In a specific embodiment, according to the collected indoor air temperature, relative humidity, and wind speed, the clothing thermal resistance is set to 0.6 clo, the personnel activity intensity is 59.8 W / m 2 , and the mean radiant temperature is set to the air temperature, and the APMV value can be calculated as follows:

[0068] APMV = PMV / (1 + λ × PMV) (1)

[0069] In Equation (1), APMV represents the predicted adaptive mean thermal sensation index; λ represents the adaptive coefficient; PMV represents the predicted mean thermal sensation index. Among them, PMV is calculated based on the water vapor partial pressure, and the water vapor partial pressure = saturated water vapor partial pressure * relative humidity. The saturated water vapor partial pressure at different temperatures can be obtained by referring to a table, which is the saturated water vapor partial pressure P at different temperatures under standard atmospheric pressure in the "Code for Thermal Design of Civil Buildings" GB 50176-2016 s value

[0070] The value of the adaptive coefficient λ is shown in Table 1

[0071] Table 1 Adaptive Coefficient λ

[0072]

[0073] The calculation method of the predicted mean thermal sensation index PMV value is as follows:

[0074]

[0075] In Equation (2), M represents the metabolic rate, and its unit is W / m 2 ; W e represents the effective mechanical power, and its unit is W / m 2 ; P a represents the water vapor partial pressure, and its unit is Pa; t a represents the air temperature, and its unit is °C; f cl represents the clothing surface area coefficient; t cl represents the clothing surface temperature, and its unit is °C; represents the mean radiant temperature, and its unit is °C; h c represents the convective heat transfer coefficient, and its unit is W / (m 2 ·K).

[0076] In Equation (2), the calculation formulas for the clothing surface temperature t cl , the clothing surface area coefficient f cl and the flow heat transfer coefficient h c are as follows respectively:

[0077]

[0078] In Equations (3) to (4), I cl represents the clothing thermal resistance, and its unit is m 2 ·°C / W; v ar represents the wind speed, and its unit is m / s

[0079] By calculating the APMV value, the comfort of the indoor thermal and humidity environment can be more accurately determined. Combining with the light environment index and air environment index, a comprehensive determination of the indoor light, thermal, humidity and air environment of the building can be achieved.

[0080] In the above step S13, when one or several indoor environment indicators are not within the range of the indoor environment determination standard, the analytic hierarchy process and the rate of change method are used to conduct a subjective and objective comprehensive weight analysis of the environment indicators, determine the indoor environment indicator with the highest comprehensive weight and use it as the optimization object, as Figure 3 and Figure 4 shown, specifically including:

[0081] S131. According to the results of pairwise importance ranking and scoring of indoor light environment indicators, thermal and humidity environment indicators, air environment indicators and sub-indicators of each indicator by indoor personnel, the subjective weight analysis result that meets the personalized needs of users is obtained by using the analytic hierarchy process.

[0082] Specifically, the analytic hierarchy process is a quantitative analysis method. First, the decision-making problem is decomposed into multiple levels to form a hierarchical structure model. Then, in each level, the factors are compared pairwise to judge their relative importance to determine the weight. Finally, by summarizing the weights of all levels, the optimal decision-making scheme is obtained.

[0083] Taking the indoor environmental quality as the target layer, the light environmental quality, thermal and humidity environmental quality, and air quality as the criterion layer, and the specific evaluation factors under each criterion layer as the sub-criterion layer, each evaluation factor contributes to the evaluation factor of the upper level. Then the hierarchical structure model of the indoor environmental quality comprehensive evaluation system is shown in Table 2.

[0084] Table 2 Hierarchical Structure Model of Indoor Environmental Quality Comprehensive Evaluation System

[0085]

[0086]

[0087] According to the hierarchical structure model, a pairwise comparison judgment matrix is constructed. Assume that the upper-level evaluation factor is X k , and it has a dominance relationship with the lower-level factors Y1, Y2…Y n . For the factors Y1, Y2…Y k judged based on X n , pairwise comparison is carried out to obtain the relative importance of each evaluation factor at this level, so as to construct the judgment matrix shown in Table 3. The assignment method of the importance degree of each factor adopts the nine-level scale method. The meaning of the matrix element a ij in the nine-level scale method is shown in Table 4.

[0088] Table 3 Judgment Matrix

[0089]

[0090] Table 4 Nine-level scale

[0091] <![CDATA[Scale a ij > <![CDATA[Scale a ji > Scale definition description 1 1 <![CDATA[Y i Factor and Y j factors are equally important]]> 3 1 / 3 <![CDATA[Y i Factor ratio Y j The factor is slightly more important]]> 5 1 / 5 <![CDATA[Y i Factor ratio Y j Factor is more important]]> 7 1 / 7 <![CDATA[Y i Factor ratio Y j is much more important than the factor]]> 9 1 / 9 <![CDATA[Y i Factor ratio Y j Factor is absolutely important]]> 2,4,6,8 1 / 2,1 / 4,1 / 6,1 / 8 Scale for states between the above priorities

[0092] Based on the nine-level scale method, a scoring group composed of relevant users scores the factors affecting the indoor environmental quality, and the opinions of each member of the group are comprehensively calculated using the arithmetic mean. According to the average scoring results Construct a judgment matrix.

[0093]

[0094] In Equation (5), n represents the number of valid scores, and a i represents the scoring result.

[0095] Perform a consistency test on the judgment matrix. First, normalize each column of the judgment matrix:

[0096]

[0097] In Equation (5), y ij represents the data in the i-th row and j-th column of the judgment matrix, represents the sum of the data in the k-th column of the judgment matrix, represents the normalized judgment matrix data.

[0098] Add up each column of the normalized matrix row by row:

[0099]

[0100] represents the sum of the data in the i-th row of the normalized judgment matrix, is the eigenvector.

[0101] Perform normalization on the eigenvector:

[0102]

[0103] represents the sum of all the data in the eigenvector.

[0104] The calculated W = [w1, w2, Lw n T is the normalized eigenvector, and the maximum eigenvalue λ max is:

[0105]

[0106] In Equation (9), Y represents the judgment matrix, (YW)​i Represents the i-th element of the vector YW.

[0107] According to the maximum eigenvalue λ max Calculate the consistency index CI.:

[0108]

[0109] In Equation (10), n′ represents the order of the judgment matrix. The smaller the CI. value, the more consistent it is. When the value is 0, it means complete consistency.

[0110] Determine the average random consistency index value RI. according to the order. The values of RI. are shown in Table 5.

[0111] Table 5 RI. values

[0112]

[0113] Then the consistency ratio CR. is:

[0114]

[0115] If CR. < 0.10, it means that the consistency of the matrix meets the requirements, and the weights are considered valid and consistent; if CR. > 0.10, it means that the consistency of the matrix does not meet the requirements and needs to be adjusted until CR. < 0.10.

[0116] Finally, the subjective weights W0 of the sub-criterion layer indicators relative to the target layer are shown in Table 6, where w i Represents the weight of the i-th factor in the criterion layer, and w ij Represents the weight of the j-th sub-criterion layer factor of the i-th factor in the criterion layer.

[0117] Table 6 Subjective weights of sub-criterion layer indicators

[0118]

[0119] S132. Score the collected indoor environmental indicators and obtain the objective weight analysis results using the rate of change method.

[0120] Specifically, use the rate of change method for objective weight analysis. According to the collected values of the indoor environment, use interpolation to score the indoor environmental indicators, obtain the rate of change of each environmental indicator, and calculate the objective weight analysis results of the deviation degree of each environmental indicator from the expected indicator.

[0121] Such as Figure 5As shown, when the working surface illuminance is less than 300 lx, the score is 0; when the working surface illuminance is greater than 300 lx and less than 450 lx, the score is 75; when the working surface illuminance is greater than 450 lx and less than 1000 lx, the score is 100; when the working surface illuminance is greater than 1000 lx and less than 2000 lx, the score is 75; when the working surface illuminance is greater than 2000 lx, the score is 0.

[0122] When the physiological equivalent illuminance in the morning in light climate zones I - IV and throughout the day in light climate zone V is less than 50 lx, the score is 0; when the physiological equivalent illuminance in the morning in light climate zones I - IV and throughout the day in light climate zone V is 100 lx, the score is 50; when the physiological equivalent illuminance in the morning in light climate zones I - IV and throughout the day in light climate zone V is 150 lx, the score is 75; when the physiological equivalent illuminance in the morning in light climate zones I - IV and throughout the day in light climate zone V is 200 lx, the score is 90; when the physiological equivalent illuminance in the morning in light climate zones I - IV and throughout the day in light climate zone V is greater than or equal to 250 lx, the score is 100.

[0123] When APMV is less than or equal to -1.0 or greater than or equal to 1.0, the score is 0; when APMV is equal to -0.7 or 0.7, the score is 25; when APMV is equal to -0.5 or 0.5, the score is 50; when APMV is equal to -0.2 or 0.2, the score is 75; when APMV is equal to 0, the score is 100.

[0124] When the CO2 concentration is less than or equal to 0.05, the score is 100; when the CO2 concentration is 0.1, the score is 75; when the CO2 concentration is 0.15, the score is 50; when the CO2 concentration is 0.2, the score is 25; when the CO2 concentration is greater than or equal to 0.25, the score is 0.

[0125] When the concentration of PM 2.5 is less than or equal to 0.035, the score is 100; when the concentration of PM 2.5 is 0.050, the score is 75; when the concentration of PM 2.5 is 0.065, the score is 50; when the concentration of PM 2.5 is 0.075, the score is 25; when the concentration of PM 2.5 is greater than or equal to 0.085, the score is 0.

[0126] According to the score, the change rate of each index is:

[0127]

[0128] In formula (12), v represents the change rate, %; x represents the index score obtained by linear interpolation.

[0129] The objective weights of each index are obtained according to the change rate of each index as follows:

[0130]

[0131] In formula (13), V i represents the objective weight of the i-th evaluation index, and v i represents the change rate of the i-th evaluation index.

[0132] S133. According to the subjective weight analysis result and the objective weight analysis result, the subjective and objective comprehensive weight is obtained through the combined assignment method, and the indoor environment index with the highest comprehensive weight is taken as the optimization object.

[0133] Specifically, the subjective and objective comprehensive weight K i is as follows:

[0134]

[0135] In formula (14), W i represents the subjective weight of the i-th evaluation index.

[0136] In the above step S2, the passive optimization measures include ventilation and shading. The passive optimization measures applicable to different optimization objects are shown in Table 7.

[0137] Table 7 Passive optimization measures applicable to different optimization objects and indoor environmental conditions

[0138]

[0139] In the above step S3, the outdoor environmental indexes include light environment indexes, thermal and humidity environment indexes, and air environment indexes. Specifically, the light environment indexes include illuminance, the thermal and humidity environment indexes include APMV, and the air environment indexes include CO2 concentration and PM2.5 concentration.

[0140] The outdoor environment judgment criteria include:

[0141] Light environment index: The illuminance value in Class I light climate region ≥ 18000 lx, the illuminance value in Class II light climate region ≥ 16500 lx, the illuminance value in Class III light climate region ≥ 15000 lx, the illuminance value in Class IV light climate region ≥ 13500 lx, and the illuminance value in Class V light climate region ≥ 12000 lx.

[0142] Thermal and humidity environment index: The suitable range of APMV is -0.5 to +0.5.

[0143] Air environment index: CO2 concentration ≤ 0.10%, PM 2.5 concentration ≤ 0.05 mg / m3.

[0144] In the above embodiments, the outdoor air temperature, relative humidity, and wind speed are collected, and the clothing thermal resistance and the personnel activity intensity are set to 0.6 clo and 59.8 W / m 2 , respectively. The mean radiant temperature is set to the air temperature, and the APMV in the outdoor environmental index is calculated using Equations (1) to (5).

[0145] By calculating the APMV in the outdoor environmental index, it is possible to more accurately determine whether the outdoor thermal and humid environment has the potential to improve the indoor thermal and humid environment. Combining with the light environment index and the air environment index, a comprehensive determination of the outdoor light, thermal, humid, and air environments can be achieved.

[0146] In a specific embodiment, if it is determined that there is one or more outdoor environmental indicators that meet the outdoor environmental determination criteria, active optimization measures are adopted. Among them, the active optimization measures include air conditioning, fresh air, and lighting. The optimization measures applicable to different optimization objects after the outdoor environmental indicators are determined are shown in Table 8.
