Description

Technical Field

[0001] This invention relates to the fields of building-integrated photovoltaics (BIPV) and off-grid life support technology, and particularly to a disguised BIPV and combined hydropower / cooling life support system and method. Background Technology

[0002] In war-torn or remote areas, power grids and water networks are often targets of military strikes. Once destroyed, people will face a survival crisis without water, electricity, or cooling.

[0003] In existing technologies, building-integrated photovoltaic (BIPV) modules are available in only one color, failing to meet the aesthetic or military camouflage requirements of buildings; colored photovoltaic panels use surface coatings, resulting in power generation efficiency losses as high as 20% to 40%. Discarded photovoltaic panels often fail due to rainbow patterns, scratches, and other defects, and there is a lack of low-cost repair technologies. In desert environments, severe dust accumulation necessitates manual cleaning, which relies heavily on water resources, and self-cleaning coatings have a lifespan of only 1 to 3 years.

[0004] Regarding air-based water extraction, condensation methods are extremely inefficient at low humidity (<40%), while adsorption methods, although suitable for arid regions, cannot produce water instantly, and neither is deeply integrated with photovoltaic systems. For cooling, off-grid air conditioning relies on batteries, whose lifespan decreases by more than 50% in high-temperature environments and carries the risk of thermal runaway; photovoltaic direct-drive cooling lacks cold energy storage and cannot provide cooling at night or on cloudy days.

[0005] More importantly, the aforementioned photovoltaic power generation, air-to-water extraction, cooling, and building decoration modules are all independent of each other, lacking a comprehensive system that can integrate camouflage and protection, clean power generation, efficient water extraction, battery-free cold storage, and automatic switching between peacetime and wartime modes. In extreme situations of water and power outages, personnel cannot rely on a single infrastructure to simultaneously obtain clean water, refrigerated medicine, and space cooling. Summary of the Invention

[0006] The technical problem to be solved by the present invention is: how to provide an integrated system and its intelligent control method that can replace building decoration materials to achieve aesthetic camouflage, generate electricity efficiently, be self-cleaning, extract water from the air, store cold without batteries, and automatically switch to independent life support when water and power are cut off.

[0007] Specifically, the present invention provides a disguised building-integrated photovoltaic and combined hydropower / cooling life support system, comprising: Disguised building-integrated photovoltaic (BIPV) modules, comprising arrays of photovoltaic panels installed on the exterior walls or roofs of buildings; The photovoltaic panel has a double-layer film structure: The interlayer colored nanofilm is set in the encapsulation layer between the front glass and the back glass of the photovoltaic panel and is attached to the inner surface of the front glass to achieve color customization. Surface functional nanofilms are sprayed onto the outer surface of the outermost glass layer of a photovoltaic panel to achieve anti-reflection, hydrophobic self-cleaning, and cooling effects. A photovoltaic power generation and energy storage module, electrically connected to the disguised building-integrated photovoltaic module, includes a lithium iron phosphate battery pack and a microgrid control unit, wherein the microgrid control unit supports grid-connected / off-grid switching; The air water intake module is electrically connected to the photovoltaic power generation and energy storage module, and includes an adsorption water intake unit and a condensation water intake unit arranged in parallel. The photovoltaic direct-drive compression refrigeration module has its power input terminal directly connected to the DC output terminal of the disguised photovoltaic building integrated module, omitting the inverter and battery, and includes a DC inverter compressor and an ice storage tank. The intelligent control module is connected to each of the above modules and is configured to execute a disguised photovoltaic building integration and water, electricity and cooling combined supply life support method.

[0008] A method for providing life support through a disguised building-integrated photovoltaic (BIPV) system and combined hydropower and cooling system includes the following steps: S1, the intelligent control module collects environmental parameters and system status parameters in real time, and calls future... Hourly irradiance prediction curve Humidity prediction curve The environmental parameters include the current irradiance. ,temperature ,humidity The system state parameters include the battery state of charge. Water level in the storage tank Ice storage tank cold storage capacity ; S2. Execute photovoltaic power generation curve-driven adsorption-desorption coordinated scheduling: as detailed below: S21. Based on the irradiance prediction curve Identify the peak photovoltaic power generation period of the day and off-peak periods; S22. The desorption stage of the adsorption-based water intake unit is forcibly scheduled to the peak period of photovoltaic power generation, utilizing direct photovoltaic electric heating or waste heat for desorption, with a desorption power of and Positive correlation: in The energy distribution coefficient. The effective area of ​​the photovoltaic panel; S23. Schedule the adsorption phase of the adsorption water intake unit to nighttime or during off-peak hours of photovoltaic power generation; S3. Perform a pre-switching of the water intake path based on humidity change trends, as follows: S31. Calculate the rate of change in humidity. Predicting the future Humidity over time:

[0009] S32, when And currently When the humidity is below the first threshold, the adsorption water intake unit is activated in advance before the humidity decreases. S33, when and In such cases, the pre-cooling mode of the condensation water intake unit should be activated in advance; S4. Implement battery-free pulsed cooling and coordinated cold storage with the building envelope, as detailed below: S41, when irradiance Below the compressor's minimum stable operating threshold When switching to pulse cooling mode: the compressor is controlled to run at the lowest stable speed for the first duration. Then stop, using mechanical and thermal inertia to maintain the evaporator at a low temperature, and stop for the second time. Then restart; S42, Dynamically Adjusting Pulsating Duty Cycle To satisfy:

[0010] S43. Connect the phase change material layer in the building walls or floors in parallel with the ice storage tank, and store the excess cold energy in the building envelope after the ice storage tank is fully loaded. S5. Perform adaptive switching between peacetime and wartime modes and maximize survival time scheduling, as detailed below: S51, when a power outage is detected and Automatically enter wartime mode; S52. In wartime mode, to maximize the system's independent uptime. To achieve the goal, establish a resource allocation optimization model:

[0011] The optimal power allocation for each module can be solved using the Lagrange multiplier method or dynamic programming. S53, when and and When the system is activated, the air intake water module will automatically stop, and all photovoltaic power will be used to maintain cooling and basic communication loads.

[0012] The beneficial effects provided by this invention are: 1. The organic unity of camouflage decoration and high-efficiency power generation. By placing the color / camouflage layer in a vacuum or inert gas encapsulation layer inside the glass (interlayer painted nanofilm, incident light absorption rate ≤5%), and placing the anti-reflection self-cleaning layer on the outside of the glass (surface functional nanofilm, contact angle ≥100°, light transmittance increased by 2%~4%), the two films have different materials, different positions, and complementary functions, achieving for the first time both customizable photovoltaic panel appearance (stone color, camouflage) and high-efficiency power generation (maintaining more than 95% efficiency of new panels). The surface functional nanofilm adopts a double-layer composite structure. The bottom layer enhances adhesion, while the top layer contains hollow nano-titanium dioxide, nano-diamond, nano-tin antimony oxide, and other components. It integrates anti-reflective properties, hydrophobic self-cleaning, cooling, and repair of rainbow patterns on waste photovoltaic panels, restoring the light transmittance of waste photovoltaic panels to more than 95% of that of new panels and reducing costs by 30% to 50%. The hydrophobic self-cleaning reduces dust residue by 80% to 85%, saving 200 to 300 tons of cleaning water per 10,000 square meters per year. The surface temperature is reduced by 10 to 15°C, and power generation is increased by an additional 5% to 12%. The coating's wear resistance and weather resistance meet a service life of 25 years.

[0013] 2. All-weather, high-efficiency air-based water intake. The system integrates both adsorption and condensation methods for water intake. The intelligent control module uses the 24-hour irradiance prediction curve to forcibly schedule the desorption phase of the adsorption water intake unit to the peak photovoltaic power generation period. The desorption power is positively correlated with the predicted irradiance. This achieves source-load matching, reducing reliance on energy storage batteries. Energy allocation coefficient. The concentration of water vapor at the desorption outlet is dynamically adjusted within the range of 0.3 to 0.8 to avoid energy waste.

[0014] Simultaneously, based on the humidity change rate, the system predicts humidity for the next 30 minutes. When the predicted humidity is about to drop below 40% and the water storage is low, the adsorption method is activated in advance for forced adsorption. When the predicted humidity is about to rise above 60% and the predicted irradiance is sufficient, the condensation method pre-cooling mode is activated in advance (causing the evaporator to drop below the dew point in advance). This pre-switching strategy eliminates the water production gap caused by the switching lag in traditional water intake systems. The dual-path synergy covers the entire range of relative humidity from 20% to 80%. Under typical desert climate conditions, the combined mode produces an average of 5-8 L / m² of water per day, which can meet the basic drinking water needs of 24 people per day during wartime.

[0015] 3. Reliable cold storage and cooling without batteries. The photovoltaic direct-drive DC inverter compressor is directly coupled to the ice storage tank, eliminating the need for inverters and batteries, thus avoiding the problems of short battery life and high risk of thermal runaway in high-temperature environments. The system adopts a pulsed cooling mode: when the irradiance is below the minimum stable operating threshold (… When the compressor operates intermittently at its lowest stable speed, it utilizes mechanical and thermal inertia to maintain the evaporator at a low temperature, thus enabling continuous ice making under low light conditions. and The temperature of the evaporator is and The rate of rise / fall between refrigerants is determined in real time, and it has fault diagnosis functions for refrigerant leaks or frost formation.

[0016] In conjunction with the building envelope, chilled water is introduced into the capillary network embedded in the walls / floors to cool the phase change materials when the ice storage tank reaches ≥90% capacity. When cooling is needed, radiant cooling of the walls is prioritized, and the system switches to ice storage tank cooling only after the wall temperature rises above 26°C. At night, the walls are pre-cooled using the natural cooling capacity of outdoor air. This strategy reduces daytime cooling load by 20%–30%, and the total chilled water storage can maintain the refrigeration of medicines in critical rooms for 24–48 hours, with a system COP of 3.2–3.67.

[0017] 4. Intelligent peacetime-wartime integration and maximized survival time. The system monitors the power grid status and water tank level in real time. In peacetime mode, it prioritizes grid-connected power generation, ice making and cooling storage, and air-to-water backup, achieving a building energy self-sufficiency rate of ≥80%. In wartime mode, it automatically and seamlessly switches (≤20ms) to off-grid operation, maximizing independent survival time. To achieve the goal, establish the system state equations ( , , The differential equations are used to perform online rolling optimization of the power weights between air intake, water extraction, ice storage, and load distribution over the next four hours using dynamic programming or model predictive control algorithms. , , The system automatically suspends air and water intake to prioritize cooling and communication. In the Dubai villa example, the average daily photovoltaic power generation is 325 kWh, while the total wartime electricity demand is 224.9 kWh, resulting in a matching rate of 144.5%, which fully meets the independent survival guarantee for more than 72 hours.

[0018] 5. Coating self-diagnosis and repair and photovoltaic panel gradient utilization: Extracting filler factor by measuring the IV curve of the photovoltaic panel. and open circuit voltage Calculate the coating degradation index. When During this process, automatic temperature cycling (45~75℃) and reverse bias (-5V~-12V) photocatalytic repair are performed, causing nano-titanium dioxide to decompose surface organic matter, resulting in a repaired surface. It can be reduced to below 0.05, extending the coating life.

[0019] Photovoltaic panels are classified into three levels based on their degradation index and cumulative power generation: Level 1 ( The first level (0.05~0.10) is used for main power generation on the south facade, the second level (0.05~0.10) is used for auxiliary power generation on the east / west facades, and the third level (>0.10) is used for the north facade or retains its camouflage function but reduces power generation access. The system automatically schedules and prioritizes the use of the first level power and adjusts the MPPT parameters to compensate for the degradation effect; when the cumulative degradation of the third level panels reaches 15%, a decommissioning report is generated. This strategy extends the economic life of the entire photovoltaic array by 3~5 years.

[0020] 6. In extreme environments such as war or disasters leading to water and power outages, this invention can independently ensure drinking water for personnel, medicine refrigeration, and space cooling: daily water production meets basic needs, ice storage tanks maintain refrigeration temperatures for 24-48 hours, and critical room temperatures are maintained at 26±2℃. Simultaneously, the camouflage or stone-colored interlayer nanofilm reduces the building's visibility, the surface functional nanofilm lowers the temperature by 10-15℃, weakens infrared signature, and low reflectivity reduces the probability of optical detection, significantly improving the concealment and survivability of military facilities. In peacetime, the system can replace dry-hanging stone cladding, achieving net-zero energy consumption buildings. Attached Figure Description

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0023] Before formally describing the present invention, a general description of the solution of the present invention will be given first to facilitate understanding.

[0024] Example 1 Please refer to Figure 1 The present invention provides a disguised building-integrated photovoltaic and combined hydropower and cooling life support system, comprising: a disguised building-integrated photovoltaic module, a photovoltaic power generation and energy storage module, an air water intake module, a photovoltaic direct-drive compression refrigeration module, and an intelligent control module.

[0025] 1. Disguised Building Integrated Photovoltaic Module The disguised photovoltaic building integrated module includes an array of photovoltaic panels installed on the exterior wall or roof of a building, wherein the photovoltaic panels replace traditional dry-hanging stone as the building decoration surface. The photovoltaic panels can be sourced from the following two sources: (1) waste photovoltaic panels that have been nano-repaired and reused; (2) newly manufactured photovoltaic panels that are directly applied.

[0026] The photovoltaic panel has a unique double-layer film structure: (1) Interlayered painted nanofilm (color and camouflage functional layer) The interlayer painted nanofilm is disposed between the two glass panes of the photovoltaic panel, specifically within a vacuum or inert gas encapsulation layer between the front and back glass panes. It is attached to the inner surface of the front glass pane via magnetron sputtering, chemical vapor deposition, or screen printing. This interlayer painted nanofilm uses a composite material of inorganic nano-pigments and high-transmittance resin to achieve customized colors for the photovoltaic panel: in civilian applications, it can be formulated to match the color of the building's dry-hanging stone cladding (such as beige, gray hemp, white hemp, etc.); in military applications, it can be painted with desert camouflage, urban camouflage, etc., reducing visible light and near-infrared identifiable features. This color layer has an absorptivity of ≤5% and a transmittance of ≥87% for incident light, without affecting the photovoltaic cell's power generation efficiency. The interlayer can be evacuated or filled with an inert gas (such as argon) to prevent oxidation and aging of the color layer, while also improving thermal insulation performance.

[0027] (2) Surface functional nanofilm (anti-reflection and self-cleaning functional layer) The surface-functional nanofilm is sprayed onto the outer surface of the outermost glass layer of the photovoltaic panel, forming a double-layer composite nanocoating: the bottom layer is an adhesion-enhancing layer with a thickness of 50-100 nm; the top layer is a multifunctional self-cleaning layer. By weight, the top layer comprises: 17-22 parts hollow nano-titanium dioxide, 5-7 parts sodium perfluorooctane sulfonate, 18-22 parts nano-diamond, and 0.5-1.5 parts nano-tin antimony oxide. This surface-functional nanofilm has the following functions: Anti-reflection: Reduces the reflectivity of the glass surface from 8-10% to 4-6%, increases light transmittance by 2-4%, and correspondingly increases power generation by 5-12%; Hydrophobic and self-cleaning: Static water contact angle ≥100°, roll-off angle ≤10°, making it difficult for sand and dust to adhere; Repairing rainbow patterns: Optical repair is performed on the rainbow patterns on the surface of waste photovoltaic panels to restore the light transmittance to more than 95% of that of a new panel; Cooling: The infrared reflection properties of nano-tin antimony oxide can reduce the surface temperature of the photovoltaic panel by 10-15℃.

[0028] The two types of films differ in material, location, and function: the interlayer painted nanofilm is located on the inside of the glass, unaffected by external wind and sand abrasion, and is responsible for color and camouflage; the surface functional nanofilm is located on the outside of the glass, in direct contact with the environment, and is responsible for optics and self-cleaning, together achieving a balance between the customizable color of the photovoltaic panel and its high-efficiency power generation performance.

[0029] 2. Photovoltaic power generation and energy storage modules The photovoltaic power generation and energy storage module includes: Photovoltaic panel array: After the above treatment, the total installed capacity is configured according to the building surface area (a typical villa project can install 20-50 kWp).

[0030] Energy storage unit: Uses lithium iron phosphate battery packs with a cycle life of ≥6000 cycles and a capacity configuration of 30% of the daily load, supporting peak shaving and valley filling.

[0031] Microgrid control unit: Includes bidirectional inverter and energy management system (EMS), supporting seamless grid-connected / off-grid switching with a switching time of ≤20 ms. In the event of grid disruption, the microgrid control unit automatically switches to off-grid operation mode.

[0032] 3. Air-to-Water Module (Dual Technology Approach) Please refer to Figure 2 The air-water extraction module incorporates two technical approaches: adsorption and condensation. It can be flexibly selected or combined to operate according to environmental humidity, temperature, energy consumption, and other conditions.

[0033] Please refer to Figure 3 Technology Route A: Adsorption-based water extraction unit. This unit is filled with composite adsorbents, including silica gel, zeolite, and metal-organic frameworks (MOFs). It adsorbs water vapor from the air at night when relative humidity is high; during the day, it utilizes waste heat from photovoltaic panels or an electric heater to desorb the water vapor from the adsorbent; the water vapor is then condensed into liquid water through air cooling or compressor refrigeration. The operation mode employs a periodic air circulation strategy, preferably an intermittent mode of "45 minutes off, 15 minutes on," which can increase the water production rate by 34% compared to continuous mode, and reduce energy consumption to 0.12 Wh / cc. This unit is suitable for arid and semi-arid regions with relative humidity of 20%-60%.

[0034] Please refer to Figure 4 Technical Approach B: Condensation-Based Water Production Unit. This unit employs a compression refrigeration system, lowering the evaporator surface temperature below the dew point, causing water vapor in the air to condense into liquid water on the evaporator surface. The refrigeration unit uses a photovoltaic direct-drive DC inverter compressor, directly electrically connected to the photovoltaic panel output. The heat exchange unit includes an evaporator, condenser, and fan. The operating mode dynamically adjusts the compressor speed based on irradiance intensity to achieve power matching. This unit is suitable for environments with relative humidity ≥50% or emergency scenarios requiring rapid water production.

[0035] Water purification unit: Regardless of the technology used, the produced water is filtered by activated carbon and disinfected by ultraviolet light to meet drinking water standards.

[0036] 4. Photovoltaic direct-drive compression refrigeration module Please refer to Figure 5 The photovoltaic direct-drive compression refrigeration module includes: Photovoltaic direct-drive DC inverter compressor: Its power input terminal is directly electrically connected to the DC output terminal of the disguised photovoltaic building integrated module, eliminating the need for inverters and batteries, and the compressor speed is dynamically adjusted according to the solar irradiance intensity.

[0037] Ice storage tank: Utilizes photovoltaic-driven refrigeration cycle to produce ice and store cold during the day. The total cold storage capacity can be configured according to demand (for example, a 1.5 m³ ice storage tank can store approximately 120 kWh of cold energy).

[0038] Terminal heat exchange unit: including fan coil unit, which extracts cold energy from ice storage tank when cooling is required.

[0039] Tests showed that the system's COP reached 3.2-3.67 at an average irradiance of 935.5 W / m², with a continuous operating time of 6.1 hours.

[0040] 5. Intelligent Control Module Please refer to Figure 6 The intelligent control module includes a PLC controller and various sensors (irradiance sensor, temperature and humidity sensor, water level sensor, current and voltage sensor, etc.), and performs the following functions: Priority scheduling: Prioritize power supply for air and water intake, then meet cooling needs, and store excess power in energy storage or ice making for cold storage.

[0041] Intelligent water intake path selection: Based on ambient humidity, temperature, and water storage level, it automatically selects adsorption, condensation, or a combination of methods.

[0042] Load forecasting: Optimize energy storage charging and discharging strategies based on weather forecasts and historical data.

[0043] Self-diagnosis of faults: When the system malfunctions, it automatically switches to manual mode to facilitate emergency repairs on the battlefield.

[0044] Survival Mode: When a water or power outage is detected (power grid failure, low water level in the water tank), the system automatically enters survival protection mode to maximize the storage time of water and food.

[0045] Example 2: This embodiment describes in detail the intelligent control method based on the system described in Embodiment 1. The method is executed by an intelligent control module, which includes a PLC controller, various sensors (irradiance, temperature and humidity, water level, current and voltage, etc.) and a communication interface.

[0046] A method for providing life support through a disguised building-integrated photovoltaic (BIPV) system and combined hydropower and cooling system includes the following steps: S1, the intelligent control module collects environmental parameters and system status parameters in real time, and calls future... Hourly irradiance prediction curve Humidity prediction curve The environmental parameters include the current irradiance. ,temperature ,humidity The system state parameters include the battery state of charge. Water level in the storage tank Ice storage tank cold storage capacity ; Specifically, the intelligent control module collects the following parameters in real time: Environmental parameters: Current irradiance (Unit: W / m²), measured by a silicon photovoltaic cell irradiance sensor installed next to the photovoltaic array; ambient temperature. (Unit: °C), measured by a PT100 temperature sensor inside the Stevenson screen; ambient humidity. (Unit: %RH), measured by a capacitive humidity sensor.

[0047] System status parameters: Battery state of charge (Unit: %), calculated by the battery management system (BMS) through current integration and voltage correction; water level in the storage tank. (Unit: L or %), measured by a submersible level transmitter; ice storage capacity. (Unit: kWh) is calculated by measuring the ice layer thickness in the ice storage tank or the inlet and outlet temperatures and flow rates of the chilled water.

[0048] Forecast data: The intelligent control module calls future... Hours (in this embodiment, the time is taken as 1 hour) Weather forecast data, including hourly irradiance prediction curves. Humidity prediction curve If real-time weather forecasts are unavailable, a forecast curve is generated based on historical data from the past 7 days using a time series forecasting model (such as ARIMA), with a time resolution of 1 hour. The sampling period for the above parameters is 1 minute, and the forecast curve is updated every 1 hour.

[0049] S2. Perform photovoltaic power generation curve-driven adsorption-desorption coordinated scheduling: It should be noted that this step actively schedules the desorption phase of the adsorption-based water intake unit to peak photovoltaic power generation periods, achieving source-load matching and reducing reliance on energy storage batteries. Specifically: S21. Based on the irradiance prediction curve Identify the peak photovoltaic power generation period of the day and off-peak periods; Specifically, based on the irradiance prediction curve The intelligent control module identifies the peak photovoltaic power generation period of the day. Peak hours are defined as follows: The continuous time interval, in which This represents the maximum predicted irradiance for the day. If no interval meets the criteria, then take [the value]. The longest consecutive two-hour period is considered the peak period.

[0050] S22. The desorption stage of the adsorption-based water intake unit is forcibly scheduled to the peak period of photovoltaic power generation, utilizing direct photovoltaic electric heating or waste heat for desorption, with a desorption power of and Positive correlation: in The energy distribution coefficient. The effective area of ​​the photovoltaic panel; Specifically, the desorption phase of the adsorption-based water intake unit is forcibly scheduled to coincide with peak photovoltaic power generation periods. The power of the desorption heating device (which can be an electric heater or a heat exchanger) is... Compared with predicted irradiance Positive correlation: in: The energy distribution coefficient has a value ranging from 0.3 to 0.8 and is dynamically adjusted by the method described in claim 5. The effective total area of ​​the photovoltaic panel (unit: m²) is 478 m² in this embodiment.

[0051] In actual operation, if the deviation between the real-time irradiance and the predicted value exceeds 20%, the real-time irradiance will be used. Alternative Make adjustments to ensure that the desorption power follows the actual power generation capacity.

[0052] S23. Schedule the adsorption phase of the adsorption water intake unit to nighttime or during off-peak hours of photovoltaic power generation; Specifically, the adsorption phase of the adsorption water intake unit will be scheduled for nighttime (when solar irradiance is lower). or during off-peak hours of photovoltaic power generation ( During the adsorption phase, the system shuts off the desorption heating device, maintaining only the circulating fan at low speed (approximately 5W) to allow the adsorbent to fully absorb water vapor during periods of relatively high ambient humidity. The adsorption phase typically lasts 8–12 hours, depending on the ambient humidity: when the humidity difference between the adsorbent outlet air and the inlet air is less than 5%, adsorption saturation is determined, and the adsorption phase can be terminated earlier.

[0053] It should be noted that the energy distribution coefficient in step S2 Dynamic adjustment methods include: S221. Monitor the water vapor concentration at the desorption outlet of the adsorption water intake unit. ; S222, when When the concentration is above the first concentration threshold, reduce To reduce desorption power; S223, when When the concentration is below the second concentration threshold, increase To enhance desorption strength; in, The adjustment range is limited to [0.3, 0.8].

[0054] Specifically, this embodiment further defines The adjustment method is to optimize desorption energy consumption.

[0055] A water vapor concentration sensor (infrared absorption principle, range 0~100 g / m³) is installed in the desorption outlet duct of the adsorption water intake unit. This sensor monitors the absolute water vapor concentration in the desorption gas stream in real time. (Unit: g / m³).

[0056] when When the desorption efficiency is high, it indicates that the adsorbent has released most of the water, and at this point, reducing the pressure is appropriate. : The single adjustment step size does not exceed 0.05, and .

[0057] when When this time, it indicates that desorption is incomplete and increases the risk of infection. : ,and .when At that time, keep the current .

[0058] If within 30 consecutive minutes and If the adsorbent level reaches 0.8, it is determined that the adsorbent has failed. The system will automatically switch to the condensation water intake unit and output an adsorbent replacement alarm.

[0059] S3. Perform pre-switching of water intake paths based on humidity change trends; This step solves the lag problem caused by traditional water intake systems switching based solely on current humidity, achieving predictive switching. Specifically: S31. Calculate the rate of change in humidity. Predicting the future Humidity over time:

[0060] Specifically, the rate of change of humidity is calculated:

[0061] Sliding window minute.

[0062] Predicting the future Humidity after minutes: .

[0063] S32, when And currently When the humidity is below the first threshold, the adsorption water intake unit is activated in advance before the humidity decreases. Specifically, when And the current water level in the storage tank When the humidity falls below a first threshold (40% of total capacity in this embodiment), the system determines that a drying period is imminent. At this point, the adsorption-based water intake unit is immediately activated for forced adsorption: even if the current humidity may still be above 40%, the circulating fan (2 m / s) is actively turned on to accelerate adsorbent saturation. Forced adsorption lasts for 1 hour, or until the difference between the adsorbent outlet humidity and inlet humidity is less than 5%. This pre-switching strategy ensures that the adsorbent is saturated when the drying period arrives, allowing for immediate desorption and water production.

[0064] S33, when and In such cases, the pre-cooling mode of the condensation water intake unit should be activated in advance; Specifically, when And predict irradiance When the system anticipates an upcoming high-temperature, high-humidity window, it pre-cools the condensation water intake unit: 15 minutes before the humidity peak, the DC inverter compressor operates at 20% of its rated power, gradually lowering the evaporator surface temperature to 2-3°C below the current dew point temperature (but without starting the condenser fan). When the humidity peak actually arrives, the evaporator is already at a low temperature and can immediately begin high-efficiency condensation, avoiding the compressor's delay of starting from room temperature (approximately 3-5 minutes).

[0065] S4. Implement battery-free pulsed cooling and coordinated cold storage with the building envelope; This step achieves continuous cooling under low-light conditions through a pulsed cooling mode and cold storage in the building envelope, without the need for batteries. Details are as follows: S41, when irradiance Below the compressor's minimum stable operating threshold When switching to pulse cooling mode: the compressor is controlled to run at the lowest stable speed for the first duration. Then stop, using mechanical and thermal inertia to maintain the evaporator at a low temperature, and stop for the second time. Then restart; Specifically, when irradiance Below the compressor's minimum stable operating threshold (This embodiment takes) When this occurs, a conventional DC inverter compressor cannot operate continuously and stably due to insufficient input power. At this time, the system automatically switches to pulse cooling mode. The compressor is controlled to run at the lowest stable speed (1200 rpm in this example) for the first duration. Then it stops, utilizing the mechanical inertia of the compressor rotor and the thermal inertia of the refrigerant circuit to maintain the evaporator at a low temperature; the second stop duration. The compressor then restarts, creating intermittent cooling pulses. During the compressor's shutdown, the condenser and evaporator fans continue to operate, relying on the residual pressure differential in the refrigerant circuit and the evaporator's metal heat capacity to continue providing cooling.

[0066] S42, Dynamically Adjusting Pulsating Duty Cycle To satisfy:

[0067] Specifically, the pulsating duty cycle is defined as:

[0068] Dynamic adjustment formula:

[0069] in The remaining empty capacity of the ice storage tank (i.e., the amount of cold that can still be stored). This represents the total capacity of the ice storage tank.

[0070] Physical meaning: When irradiance near hour, The duty cycle is mainly determined by the available capacity of the ice storage tank: the smaller the available capacity ( The smaller the value, the larger the duty cycle. When the irradiance is much lower than... When the ice storage tank is full, the duty cycle is reduced proportionally to avoid frequent compressor starts and stops. When the ice storage tank is completely empty, the duty cycle is 1, and the compressor runs continuously; when the ice storage tank is completely empty... When the duty cycle is 0, cooling stops.

[0071] S43. Connect the phase change material layer in the building walls or floors in parallel with the ice storage tank, and store the excess cold energy in the building envelope after the ice storage tank is fully loaded. It should be noted that the first duration of the pulse cooling mode in step S41... Second duration The methods for determining this include: S411. Real-time monitoring of evaporator temperature after compressor stops. recovery rate ; S412, Set the upper limit threshold of the evaporator temperature. and lower threshold ,in This refers to the dew point temperature.

[0072] As one embodiment, this embodiment further limits... and The specific steps for determining this.

[0073] A patch-type PT100 temperature sensor is installed on the evaporator outlet pipe wall to monitor the evaporator temperature in real time. Set the upper limit threshold for the evaporator temperature. and lower threshold : .

[0074] in The dew point temperature is calculated from temperature and humidity sensor data using the Magnus formula:

[0075] The value of is: when the compressor is running at its lowest stable speed, the evaporator temperature is from Down to The required time. The system measures this time in real time, typically ranging from 20 to 60 seconds.

[0076] Value of: After the compressor stops, the evaporator temperature starts from... rebounded to Time required. Typical values ​​are 30 to 120 seconds.

[0077] The system remeasures after each pulse cycle. and And update the parameters.

[0078] Monitor the rate of temperature recovery of the evaporator after the compressor stops. When this rate increases abnormally, exceeding 20% ​​of the historical average, it is determined that a refrigerant leak or evaporator frosting may occur. The system automatically triggers a fault alarm and switches the refrigeration unit of the air water intake module to the adsorption water intake unit for auxiliary refrigeration (using the cold energy generated during desorption to replenish the ice storage tank).

[0079] It should be noted that this system connects the phase change material layer in the building walls or floors in parallel with the ice storage tank to achieve auxiliary cold storage in the building envelope.

[0080] The phase change material and capillary network setup is as follows: A capillary network (PE-RT pipes with an outer diameter of 4.3 mm, a wall thickness of 0.8 mm, and a pipe spacing of 50 mm) is pre-embedded on the inner side of the building's exterior walls or in the floor slab structure. Chilled water circulates within the capillary network. Paraffin-based composite phase change material (melting point 18~22℃, latent heat of phase change ≥180 kJ / kg) is filled around the capillary network and encapsulated in a high thermal conductivity polymer bag.

[0081] The specific control strategy for collaborative cold storage of the building envelope in step S43 is as follows: S431, when the ice storage tank's cooling capacity When the building envelope is activated, the chilled water is introduced into the capillary network embedded in the wall or floor slab. S432, Monitoring wall surface temperature ,when When the temperature is below the indoor dew point, the flow rate of the wall-mounted cold storage circuit will be automatically reduced or cut off. As one example, Specifically, when the ice storage tank's cooling capacity At this time, the building envelope's cold storage circuit is activated. The three-way valve switches, introducing chilled water (approximately 0-4°C) from the ice storage tank outlet into the wall / floor capillary network to charge the phase change material with cold. The charging process continues until the wall surface temperature reaches a certain level. The temperature drops to 16°C or the ice storage tank's cooling capacity drops to 0.8. Stop when the time comes.

[0082] During the cooling process, monitor the surface temperature of the wall. .when When the temperature is below the indoor dew point, the flow rate of the wall cold storage circuit is automatically reduced or cut off to prevent condensation on the wall surface.

[0083] S433. When cooling is required, the wall cold storage circuit should be turned on first to use the wall radiation for cooling. When the wall temperature rises above the preset value, the ice storage tank or the compressor direct drive cooling should be started. Specifically, when indoor cooling is needed, the wall-mounted cold storage circuit is activated first: the ice storage tank circuit is closed, and the wall capillary network circuit is opened, allowing chilled water to circulate within the wall and supply cooling to the room through wall radiation and convection. When the wall temperature rises above 26°C, the system switches to ice storage tank cooling (fan coil units are turned on for forced convection). If the ice storage tank's cooling capacity is also exhausted and the current irradiance is sufficient ( If the compressor is activated, it will directly drive the refrigeration process, simultaneously charging the ice storage tank and the walls with cold.

[0084] S434. At night, the natural cooling capacity of outdoor air is used to pre-cool the walls directly through fan coil units.

[0085] Specifically, between 10:00 PM and 6:00 AM the following day, when the outdoor temperature is more than 2°C lower than the indoor set temperature, the compressor is turned off, and only the fan coil unit or fresh air system is turned on to directly introduce outdoor air into the wall capillary network for pre-cooling. If the outdoor humidity is high, it is first dehumidified through the dehumidification impeller in the adsorption water intake unit before being introduced. Nighttime pre-cooling can reduce the wall temperature by 3-5°C in the morning, significantly reducing the daytime cooling load.

[0086] S5. Perform adaptive switching between peacetime and wartime modes and maximize survival time scheduling; This step enables the system to automatically switch between normal and power / water outage states, and maximizes independent operating time in wartime mode using mathematical optimization methods. Specifically: S51, when a power outage is detected and Automatically enter wartime mode; Specifically, the system continuously monitors the grid voltage and the water level in the storage tank. The system will automatically enter wartime mode when both of the following conditions are met: Power grid outage: The effective value of the grid-side voltage is detected by a voltage transformer as being lower than 50% of the rated value for more than 10 seconds; The water level in the storage tank is below the first threshold: In this embodiment, Total capacity. Otherwise, the system will remain in or switch to normal mode.

[0087] The switching action is executed by the microgrid control unit, and the grid-connected / off-grid switching time is ≤ 20 ms, ensuring that critical loads (such as medicine refrigerators) are not interrupted in power supply.

[0088] S52. In wartime mode, to maximize the system's independent uptime. To achieve the goal, establish a resource allocation optimization model:

[0089] The optimal power allocation for each module can be solved using the Lagrange multiplier method or dynamic programming. Specifically, in wartime mode, the system maximizes its independent operating time. To achieve the goal, we establish and solve a resource allocation optimization model.

[0090] State equations (discretization, sampling time) minute): in: This represents the total capacity of the energy storage battery (30 kWh in this embodiment). The predicted photovoltaic power generation value for the k-th time period (from...) ); ; The water production rate function is related to the power allocated to the water intake module. Calibration was achieved through experiments; This refers to the ice-making power, which is related to the compressor speed. The cooling power requirement is calculated by the PI controller based on the difference between the set indoor temperature and the actual temperature.

[0091] Terminal constraints:

[0092] This embodiment takes (Minimum daily water intake per person). (The minimum amount of cold required to maintain the refrigeration of medicines).

[0093] The control constraints are as follows:

[0094] The optimization solution method is as follows: Receding Horizon Optimization is used to predict the time domain. (4 hours), control time domain (1 hour). At each optimization time step, solve the following equivalent optimization problem (maximizing) (Equivalent to minimizing the rate of resource consumption)

[0095] in and The penalty weight reflects the urgency of the current water and cooling shortages. The weight is dynamically adjusted: when... hour, Increase to 0.7; when hour, Increase to 0.7; the default is 0.5.

[0096] The solution is obtained using dynamic programming (DP), with state space discretization: the SOC is discretized into 21 points with a step size of 5%. Use 10L increments (0~240L). The computational complexity is acceptable on an ARM Cortex-M7 controller (single solution time < 0.5 seconds) with a 10% increment.

[0097] The first set of control variables obtained from the solution will be rolled over every 15 minutes. , The data is distributed to each execution module. The state is remeasured and optimized on a rolling basis in the next time step. When computing resources are limited or sensors fail, the system automatically falls back to fuzzy rule scheduling as a backup.

[0098] S53, when and and When the system is activated, the air intake water module will automatically stop, and all photovoltaic power will be used to maintain cooling and basic communication loads.

[0099] In wartime mode, if both conditions are met , , This indicates that electricity is currently the most scarce resource, while water and cooling capacity are relatively abundant. At this point, the system automatically suspends the air-to-water module, using all photovoltaic power to maintain cooling (ensuring the supply of medicines and food) and basic communication loads. This strategy can extend the overall lifespan.

[0100] It should be noted that the method also includes a self-diagnosis and online repair step for the surface functional nanofilm. This step periodically evaluates the performance of the functional coating on the photovoltaic panel surface and performs electro-repair to extend the coating's lifespan, as detailed below: S61. Extract the fill factor by measuring the IV curve of the photovoltaic panel under standard irradiance. and open circuit voltage Calculate the coating performance degradation index:

[0101] Specifically, once a month (or triggered when the photovoltaic panel's power generation efficiency drops by more than 5%), the system uses the inverter's built-in MPPT scanning function to apply a scanning voltage (0.5V step, 0.1-second dwell time) from 0 to open-circuit voltage to the photovoltaic panel at night or when the irradiance is below 50 W / m², simultaneously collecting current and plotting the IV curve. The short-circuit current is extracted from the IV curve. Open circuit voltage Maximum power point current and voltage ; Calculate the fill factor:

[0102] Initial values ​​were measured and stored during system installation. and .

[0103] The coating performance degradation index is calculated as follows:

[0104] Degradation Index This reflects the recombination loss caused by the aging of surface functional nanofilms (increased surface recombination leads to a decrease in fairing (FF), and increased series resistance leads to a decrease in series resistance (SS)). decline)..

[0105] S62, when At that time, the online repair process is initiated: the surface temperature of the photovoltaic panel is controlled to circulate, and a reverse bias voltage is applied to the photovoltaic panel through the inverter, so that the nano-titanium dioxide in the surface functional nanofilm produces a photocatalytic effect; S63. After repeating the temperature cycle for a preset number of times, remeasure the IV curve. If the repair is successful, a manual maintenance alarm will be output.

[0106] Specifically, when Initiate the online repair process: Step 1: Temperature Cycling The inverter adjusts the operating point of the photovoltaic panel, causing its output power to periodically vary between 50% and 100% of the rated power, thus controlling the surface temperature of the photovoltaic panel to cycle between 45℃ and 75℃. Specifically, the operating voltage is set alternately between 0.7 and 1.1 times the maximum power point voltage, switching every 10 minutes for 1 hour. This temperature cycling softens organic contaminants adhering to the surface and promotes the healing of microcracks in the nano-coating.

[0107] Step 2: Reverse bias photocatalytic repair After the temperature cycle is completed, a reverse bias voltage is applied to the photovoltaic panel through the inverter: reverse bias voltage value: -5V to -12V (absolute value not exceeding 80% of the open circuit voltage); application time: 10~15 minutes; current limit: not exceeding 10% of the short circuit current.

[0108] Reverse bias generates a uniform electric field on the photovoltaic panel surface, driving photogenerated carriers to migrate to the surface and undergo a photocatalytic reaction with nano-titanium dioxide, decomposing organic pollutants adsorbed on the coating surface. At the same time, the Joule heat (approximately 50~60℃) generated by reverse bias further promotes the densification of the nano-coating and the surface enrichment of hydrophobic groups (-CF3).

[0109] Step 3: Evaluation of Repair Results After the repair is completed, the IV curve is remeasured and a new calculation is performed. :like If the repair is successful, the system will return to normal operation; If partial repair is determined, the number of repair attempts is recorded, and repair will be attempted again in the next cycle; if If the repair fails, a manual maintenance alarm will be issued (via display screen or remote communication), suggesting replacement or recoating of the surface functional nanofilm. If the repair attempt fails to restore the surface to its original state after three attempts, the issue persists. When this happens, the system marks the photovoltaic panel as permanently degraded and performs gradient utilization scheduling.

[0110] It should be noted that the method also includes a gradient utilization scheduling strategy for waste photovoltaic panels. This step, based on the coating degradation index and cumulative power generation, performs hierarchical management and scheduling of different components in the photovoltaic panel array to maximize the overall system lifespan and economic benefits, as detailed below: S71, Coating performance degradation index obtained through step S61 Combined with the cumulative power generation of photovoltaic panels Photovoltaic panels are divided into three grades: Level 1: Used for the main power generation surface on the south facade; Level 2: Used for auxiliary power generation on the east / west facades; Level 3: Used on the north facade or as camouflage decorative panels; Specifically, the system database maintains a unique ID for each photovoltaic panel and its operational history. Every day at midnight, based on the latest measurements... and cumulative power generation (Unit: kWh) Photovoltaic panels are divided into three grades, as shown in Table 1 below: Table 1 Photovoltaic Panel Grades

[0111] in This represents the rated total power generation of the photovoltaic panel over 25 years under standard test conditions (kWp × 25 years × annual equivalent hours). In this embodiment, the annual equivalent hours are taken as 1290 hours.

[0112] S72. The system automatically records the classification information of each photovoltaic panel and prioritizes the use of power from the first-level photovoltaic panels during energy dispatch. The third-level photovoltaic panels are only connected in extreme emergency situations. Specifically, the automatic scheduling strategy is as follows: Power generation dispatch: The MPPT controller prioritizes the use of power from the primary photovoltaic panels. When the output power of the primary photovoltaic panels is insufficient to meet the load demand, the secondary and tertiary photovoltaic panels are connected in sequence. The tertiary photovoltaic panels are only connected in the following situations: (1) The total output of the primary and secondary panels is still lower than the load demand and (2) Entering emergency mode and having no other power source.

[0113] Camouflage Priority: For Level 3 PV panels, even if their power generation capacity is severely reduced, their camouflage function as building facade decorative panels is still retained. The system controls the DC-DC converter connected to the Level 3 PV panels to be in standby mode (no power output), retaining only their physical shading and color camouflage functions.

[0114] MPPT parameter adjustment: For secondary and tertiary photovoltaic panels, the system automatically reduces the maximum power point voltage. The offset is To match the drift of the optimal operating point caused by the increase in series resistance; at the same time, the MPPT perturbation step size is increased (from the default 0.5% to 1.5%) to speed up the response.

[0115] S73. When the cumulative number of three-level photovoltaic panels reaches a certain amount, a decommissioning report is generated, and it is recommended to dismantle them in a centralized manner and send them to a centralized repair center for recoating the surface functional nanofilm.

[0116] Specifically, when the cumulative number of tertiary photovoltaic panels reaches 15% of the total installed capacity, the system generates a decommissioning report, which includes: the ID of each tertiary photovoltaic panel, its installation location, and so on. Value, cumulative power generation; suggested handling method: if It is recommended that the parts be removed and sent to a repair center for recoating with a functional nanofilm. Environmentally friendly recycling is recommended. The report can be sent to the operations center via the network or displayed on a local screen.

[0117] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
