Humidity sensors, temperature sensors, heat flow sensors and differential thermocouple arrays are deployed in all curtain wall areas to achieve high-frequency acquisition of key condensation perception data such as temperature T, humidity RH, heat flux Q and thermal power P every 5 seconds. The system builds a central control system through local area network technology, and uses the wireless communication module of the sensor to achieve real-time data transmission with the central processing node, ensuring the ability to collect heat and humidity data in multiple regions, with low latency and high synchronization. This module effectively solves the problems of single perception dimension, low acquisition frequency and high data transmission delay in the existing BIPV curtain wall system, and improves the ability to capture rapid fluctuations in microclimate and the interactive state of heat and humidity. Compared with the traditional method of relying only on indoor temperature and humidity monitoring points or centralized air conditioning parameters for judgment, this module realizes the real-time acquisition of multi-physical field linkage data at the curtain wall partition level, providing high-resolution and high-responsive basic data support for subsequent condensation potential analysis and thermal inertia identification.

[0067] Example 3
[0068] See also Figure 1 and Figure 2, specifically: the central control processing module includes a data processing unit, a feature extraction unit, and a dew point temperature analysis unit;
[0069] The data processing unit receives the condensation perception data in real time in the central control system and preprocesses the condensation perception data. The preprocessing includes data synchronization and timestamp unification, denoising, and dimensionless processing;
[0070] Data synchronization and timestamp unification are based on the control cycle of the central control system for all condensation perception data. Intermediate data is aligned by linear interpolation to ensure consistent data input at the same control moment;
[0071] Denoising uses a sliding window Z-score anomaly detection to judge the outliers in the condensation perception data and replaces the outliers with the mean method to remove the outliers in the condensation perception data;
[0072] Dimensionless processing uses the Min-Max normalization method to eliminate the influence of dimensions in the condensation perception data;
[0073] The feature extraction module extracts features from the preprocessed condensation perception data, obtains the humidity fluctuation amplitude ▽RH and the heat flux offset △Q of each curtain wall area respectively, and summarizes the humidity fluctuation amplitude ▽RH and the heat flux offset △Q with the preprocessed condensation perception data to obtain a standardized data set;
[0074] Among them, the humidity fluctuation amplitude ▽RH and the heat flux offset △Q are calculated and obtained from the condensation perception data after eliminating two through preprocessing, that is, dimensionless parameters;
[0075] The humidity fluctuation amplitude ▽RH is obtained by calculating the standard deviation by saving the current humidity RH and the historical values within a fixed time period time window;
[0076] The heat flux offset △Q is obtained by interpolating the current heat flux Q and the average heat flow value at the past t-△t moment, where △t represents the time interval.
[0077] The dew point temperature analysis unit constructs a dew point analysis formula, extracts the temperature T and humidity RH in the standardized data set, inputs them into the dew point analysis formula, and performs joint calculation to output the dew point temperature Tdp of each curtain wall area, and analyzes the dew point conditions of the air in different curtain wall areas;
[0078] The dew point temperature Tdp is calculated and output through the following dew point analysis formula;
[0079] ;
[0080] where ln represents the natural logarithm function, a represents the slope control factor, the slope control factor of the sensitivity of the water vapor saturation pressure in the air to temperature, b represents the vapor constant of water, reflecting the critical curvature at which water vapor reaches saturation at a specific temperature point, Tdp i represents the dew point temperature of the i-th curtain wall area, T i represents the temperature of the i-th curtain wall area, RH i represents the humidity of the i-th curtain wall area, and both a and b are dimensionless;
[0081] The physical meaning of the formula is: This is a formula that maps the temperature T and humidity RH in the air together to the critical temperature at which the air reaches the saturation state.
[0082] In this embodiment, the system receives the condensation perception data from the multi-dimensional perception module through the central control system by the data processing unit, and performs data synchronization, anomaly elimination, and dimensionless processing on it. Through timestamp alignment and linear interpolation, the data unified acquisition period between different sensors is realized, and the timeliness consistency of multi-source input within the same control period is guaranteed. With the help of the sliding window Z-score algorithm, the system can accurately identify and correct sudden outliers, significantly improving data stability and analysis reliability. Through Min-Max normalization, dimensionless processing of parameters is realized, making the subsequent calculation model have strong versatility and comparability. On this basis, the feature extraction unit extracts the humidity fluctuation amplitude ▽RH and the heat flux offset △Q of each curtain wall partition for the preprocessed data, constructs a standardized data set, and effectively captures the thermal and humidity disturbance trends in the curtain wall system. Further, the dew point temperature analysis unit outputs the dew point temperature Tdp of each partition based on the dew point temperature calculation model with clear physical meaning by inputting the standardized temperature T and humidity RH, so as to realize the quantitative modeling of the critical state of air condensation.

Through this module, the system has been significantly improved in terms of data accuracy, processing stability, trend sensitivity, and modeling physicality, laying a high-quality basic data and modeling ability for realizing multi-partition dynamic condensation trend recognition and intelligent linkage control, and then improving the operation intelligence level and environmental adaptability of the entire BIPV curtain wall system.
[0083] Embodiment 4
[0084] Please refer to Figure 2 and Figure 3 , specifically: The condensation potential identification module includes a condensation potential analysis unit and a condensation potential evaluation unit;
[0085] The condensation potential analysis unit standardizes the temperature T and humidity RH in the dataset, calculates the temperature change and humidity change per unit time respectively, and then combines with the dew point temperature Tdp of each curtain wall area to perform a correlation calculation to output the condensation potential index CPI, which is used to measure the air condensation situation of each curtain wall area;
[0086] The condensation potential index CPI is calculated and output through the following algorithm formula;
[0087] ;
[0088] In the formula, CPI i represents the condensation potential index of the i-th curtain wall area, k represents the weight factor of the temperature change rate, which controls the amplification effect of temperature change on the condensation risk, u represents the weight factor of the humidity change rate, which controls the amplification degree of humidity rise on the risk assessment, d represents the calculus variable, and dt represents the time calculus variable;
[0089] Among them, represents the distance between the current temperature and the dew point temperature. The smaller the difference, the greater the condensation risk;
[0090] represents the temperature change rate per unit time, represents whether the temperature is dropping rapidly. A rapid temperature drop amplifies CPI and is more likely to cause condensation;
[0091] represents the humidity change rate per unit time, represents whether the humidity is rising rapidly. An increase in moisture causes faster saturation and amplifies CPI;
[0092] The physical meaning of the formula is a numerical index used to judge whether there is a risk of impending condensation in a curtain wall partition. Its essence is: combining the current temperature and humidity state T, RH at the spatial position with their change trends to form a dynamic response value, which is used to express whether the area is rapidly approaching the condensation point.
[0093] The condensation potential assessment unit sets the first condensation threshold F1 and the second condensation threshold F2 respectively by comparing the condensation potential indices CPI of different curtain wall areas and analyzing the condensation potential indices CPI before re-condensation occurs and when the condensation trend exists but has not occurred. That is, the condensation potential index CPI at the time of re-dew is set as the second condensation threshold F2, and the condensation potential index CPI at the critical dew is set as the first condensation threshold F1. Then, the obtained condensation potential index CPI of each area is preliminarily compared and evaluated with the first condensation threshold F1 and the second condensation threshold F2 to output the condensation risk level division value L of the i-th curtain wall area i, determine the condensation risk of the curtain wall and classify the condensation risk level based on the preliminary comparison and evaluation results. The specific evaluation content is as follows;
[0094] When the condensation potential index CPI of the i-th curtain wall area i ≤ the first condensation threshold F1, at this time, the condensation risk level classification value L of the i-th curtain wall area i The output result is 0, indicating that there is no current condensation risk, and the current curtain wall area is marked as the safe level;
[0095] When the first condensation threshold F1 < the condensation potential index CPI of the i-th curtain wall area i ≤ the second condensation threshold F2, at this time, the condensation risk level classification value L of the i-th curtain wall area i The output result is 1, indicating that the current is in a critical risk, the current curtain wall area is marked as the warning area, and the acquisition period is adjusted to be acquired once every 2 seconds for continuous monitoring;
[0096] When the condensation potential index CPI of the i-th curtain wall area i > the second condensation threshold F2, at this time, the condensation risk level classification value L of the i-th curtain wall area i The output result is 2, indicating that the current is in an abnormal risk, the current curtain wall area is marked as the abnormal risk area, and at this time, the partition heat relationship perception module is executed to perform active thermal regulation and shading coordination.
[0097] In this embodiment, the condensation potential identification module of the system consists of a condensation potential analysis unit and a condensation potential evaluation unit. By modeling and calculating the exponential relationship between the standardized temperature T, humidity RH, and the dew point temperature Tdp of each curtain wall area, a predictive quantitative index, the Condensation Potential Index (CPI), is constructed. This module can capture the change rate of temperature and humidity parameters in each partition in real time and introduce a weighted correction mechanism for the temperature change rate and the humidity increase amplitude, realizing an algorithm upgrade from absolute value perception to change trend perception. Compared with the traditional static method that relies on the over-limit judgment of single-point temperature and humidity to determine condensation, this module can give early warnings of the dynamic process in which the humid and hot state of the air rapidly approaches the condensation point, effectively enhancing the forward-looking judgment ability of the system. Through the first condensation threshold F1 and the second condensation threshold F2 set by the condensation potential evaluation unit, the system can discretize the CPI value into three categories of condensation risk levels, realizing the qualitative classification of the safety level, warning level, and abnormal level of each curtain wall area. Combined with the level feedback mechanism, the data acquisition frequency and control strategy are dynamically adjusted. This method breaks through the technical limitation of the existing control strategy that only responds passively after condensation occurs, realizing the predictive response characteristic of "the system takes action before the risk appears".

[0099] Please refer to Figure 1 and Figure 2 Specifically, the partition heat pipe sensing module extracts the heat power P, temperature T, and humidity fluctuation amplitude ▽RH of different regions from the standard dataset, performs correlation calculations to output the thermal inertia index HCI, and analyzes the internal heat accumulation effect of all curtain wall areas due to the continuous heat generation of BIPV.
[0100] The thermal inertia index HCI is calculated and output through the following algorithm formula;
[0101] ;
[0102] In the formula, HCI i represents the thermal inertia index of the i-th curtain wall area, t0 represents the initial moment, P i (t) represents the BIPV heat power of the i-th curtain wall area at time t, Tavg represents the historical average temperature from the initial moment t0 to time t, w1 represents the sensitivity of heat accumulation, w2 represents the temperature offset penalty coefficient, and w3 represents the humidity fluctuation amplification factor, all of which take dimensionless values;
[0103] It represents the heat accumulation amount, which is the total time of heat energy accumulation;
[0104] It represents the difference between the current temperature T and the average temperature of the curtain wall area. If the current temperature T is much higher, it means that the heat has not dissipated yet, that is, the heat retention is serious; if it is lower than the average temperature, it means that the area has started to cool down, which can be used as a basis for judging the natural cooling trend.
[0105] In this embodiment, the heat inertia perception module of the system extracts the heat power P, temperature T and humidity fluctuation range ▽RH of each curtain wall area in the standardized dataset, and calculates and outputs the heat inertia index HCI based on the relationship between the cumulative heat and the current thermal state offset within a time period, so as to identify and quantify the local area heat retention effect caused by the continuous heat generation of BIPV components. This module not only considers the accumulation trend of the regional heat generation power, but also introduces the weighted coefficients of temperature offset and humidity disturbance factors, realizing the comprehensive coupling modeling of three factors: "energy accumulation", "thermal field imbalance" and "microclimate instability". By judging the deviation direction and intensity between the current temperature and the historical average temperature, the system can accurately judge whether the partition is in a state of un-recovered thermal imbalance or the start of natural cooling release. Compared with the traditional BIPV system that relies on fixed-period temperature sampling or surface temperature rise judgment, this module has the composite perception advantages of dynamic analysis + trend modeling + multi-factor regulation, breaking through the technical bottleneck of "unable to identify the risk of heat inertia residue" in the existing technology. In the case where the condensation potential is high and the heat retention has not been released, this module can intervene in time and serve as an important trigger basis for structural-level response control, effectively preventing the occurrence of lagging condensation caused by the un-dissipated internal waste heat. At the same time, this module provides the control system with a more accurate understanding of the partition thermal environment, supporting the system to perform more forward-looking and structurally adaptable shading, heat conduction or energy management responses, significantly improving the heat control accuracy, response timeliness and condensation suppression effect of the BIPV curtain wall system.

[0109] The response control function U is calculated and output through the following algorithm formula;
[0110] ;
[0111] where U i represents the response control function of the i-th curtain wall area, represents the response smoothing factor, which is used to map the input value to a continuous, stable, and controllable output range as the basis for system behavior decision-making, represents the thermal disturbance linkage term. a1, a2, a3, and a4 respectively represent the condensation potential index CPI, the heat output inertia index HCI, the risk level division value L, and the weight coefficient of thermal disturbance linkage. Among them, a1 + a2 + a3 + a4 = 1, and its specific values are set by the user.
[0112] The decision control unit performs secondary comparison and evaluation based on the output result of the response control function U, and performs hierarchical control based on the secondary comparison and evaluation result to execute different control behaviors. The specific evaluation content is as follows;
[0113] If the response control function U of the i-th curtain wall area i ∈[0, 1), at this time, primary control is performed on the current curtain wall area. The primary control reduces the light transmittance of the curtain wall glass by 10%, reduces the heat generation efficiency of the BIPV module by 10%, and performs natural ventilation assistance;
[0114] If the response control function U of the i-th curtain wall area i ∈[1, 2), at this time, secondary control is performed on the current curtain wall area. The secondary control adjusts the angle of the sunshade device to 45°, controls the BIPV module to reduce by 30%, and performs mechanical air supply assistance;
[0115] If the response control function U of the i-th curtain wall area i ∈[2, 3), at this time, tertiary control is performed on the current curtain wall area. After the tertiary control is triggered, the ATFB active thermal buffer mechanism is started for structural heat conduction;
[0116] If the response control function U of the i-th curtain wall area i ∈[3, 4), at this time, quaternary control is performed on the current curtain wall area. After the quaternary control is triggered, the current curtain wall area is completely closed, full shading and power generation suspension are performed, the ATFB active thermal buffer mechanism switches to the maximum heat conduction mode, the alarm is marked as the condensation black zone, and the user is notified to intervene for pre-maintenance.

[0119] The micro-channel air interlayer controls air heat conduction and air insulation by setting a 20mm thick closed air layer behind the curtain wall glass. At the same time, a micro-channel network, such as honeycomb and grid shapes, is designed inside the closed air layer to guide air flow and stillness.
[0120] Phase change thermal conductive material layer PCM controls condensation caused by sudden temperature changes by adding a 5mm thick phase change material layer, such as paraffin, PEG composite lipid and saline gel, into the microchannel air interlayer;
[0121] The microstructured thermal valve sheet array is achieved by evenly arranging micro thermal response devices in the microchannel air interlayer. The thermal response devices include shape memory alloys and bimetallic thermal sheets. Based on the shape memory alloys and bimetallic thermal sheets, they automatically respond to temperature changes and open and close local thermal channels.
[0122] In this embodiment, the comprehensive control decision module of the system is composed of a response analysis unit, a decision control unit and a thermal buffer unit, and a partition linkage intelligent response decision system for the BIPV curtain wall system is constructed. The response analysis unit integrates key parameters such as the condensation potential index CPI, the thermal inertia index HCI, the condensation risk level L and the thermal disturbance index △Q, and constructs the response control function U through weighted combination, and introduces the response smoothing factor to modulate the function output so that it remains in a stable, continuous and controllable range, as the logical basis for the hierarchical control behavior of the whole system. Compared with the traditional mode based on a single environmental threshold trigger, this method realizes multi-dimensional factor fusion and dynamic response output, and enhances the decision accuracy and environmental adaptability of the control logic. On the basis of the response control function U, the decision control unit sets the interval classification standard and executes a step-by-step control strategy from level one to level four, covering the whole process response mechanism such as mild shading, heating limit control, ventilation intervention, structural heat conduction and final condensation black area closure. In particular, in the hierarchical control, the system will link the thermal buffer unit to start the ATFB active thermal buffer mechanism, automatically select the thermal conduction or insulation state, and realize the structural level response behavior. ATFB is composed of a microchannel air interlayer, a phase change thermal conductive material layer PCM and a microstructured thermal valve array. It does not rely on traditional air conditioning or energy-consuming equipment, and can quickly adjust and guide the local heat flux state under severe thermal disturbance or condensation risk. It has the characteristics of structural self-control, independent partitioning, and passive activation. The introduction of this module enables the system to have a full-link intelligent closed-loop capability from parameter identification to trend modeling to hierarchical control, and then to structural response. It completely breaks through the limitations of the existing technology such as single response means, insufficient structural participation ability, and drastic control behavior jumps, and realizes the intelligent transition from "detection environment" to "control physics". Ultimately, it significantly improves the BIPV curtain wall system's resistance to condensation risks, the efficiency of eliminating thermal disturbances, and the level of coordinated optimization of overall energy efficiency, and has high scalability and practical engineering application value.
