Traditional indoor environmental control systems mainly focus on a single function, such as cooling or heating, and it is difficult to meet multiple environmental needs at the same time. In addition, these systems have great challenges in energy consumption management, especially when dealing with changes in different seasons and usage scenarios. It is often difficult to achieve efficient and energy-saving operation, resulting in energy waste and increased operating costs.

[0003] Although the multifunctional indoor environment adjustment systems on the current market integrate multiple functions such as cooling, heating, dehumidification, humidification, fresh air and air purification, they still have deficiencies in intelligent control and system integration. Some systems lack intelligent scheduling algorithms and cannot dynamically adjust the operating status according to real-time environmental parameters, resulting in uncoordinated control of temperature, humidity and air quality. In addition, many devices have slow response speeds and insufficient control accuracy when implementing independent temperature and humidity control in different areas, affecting the user's comfort experience.

[0004] Although the existing indoor environment adjustment technology has made some progress in multi-functional integration and partial intelligence, there is still room for further improvement in the overall system performance and user experience optimization.

[0049] An energy management module, electrically connected to the control module, comprising a renewable energy collection device and an energy storage device, for supplying energy to each execution device;

[0050] Communication module, used to realize data transmission between various functional modules;

[0051] The ground radiation control system is electrically connected to the control module, and comprises a temperature and humidity detection unit and a ground temperature control execution unit, and adjusts the operating parameters of the ground temperature control execution unit according to the indoor humidity and temperature.

[0052] Specifically, the sensor module includes a distributed temperature sensor, a capacitive humidity sensor, a laser scattering PM2.5 sensor, an infrared CO2 sensor, a semiconductor TVOC sensor and a formaldehyde-specific sensor.

[0053] The sensor communicates with the control module using a bus connection to ensure stable data transmission and synchronous collection. The bus connection has the advantages of simplifying wiring, reducing system complexity and improving data transmission efficiency, and is suitable for centralized management and data processing of multiple sensors. The sensor module has good anti-interference ability and can work stably in complex indoor environments to ensure data accuracy and reliability.

[0054] Distributed temperature sensors use high-precision thermistor (RTD) technology, have a measurement accuracy of ±0.5°C, and can work stably in the range of -10°C to 50°C. By arranging sensors at multiple key locations indoors, comprehensive monitoring of the temperature in different areas can be achieved to avoid data deviation caused by a single sensor location.

[0055] The capacitive humidity sensor has a measurement accuracy of ±2% relative humidity (RH) and can sensitively respond to changes in ambient humidity within the range of 0% to 100% RH. The sensor uses highly sensitive capacitance change detection technology to capture small fluctuations in indoor humidity in real time, providing accurate data support for the humidity regulation of the system.

[0056] Laser scattering PM2.5 sensor has 0-500μg / m 3 The sensor has a wide detection range and can efficiently and accurately measure the concentration of fine particulate matter (PM2.5) in indoor air. Using laser scattering technology, the sensor has excellent detection sensitivity and response speed, and can reflect changes in air quality in real time.

[0057] The infrared CO2 sensor has a measurement range of 0-5000ppm and uses non-dispersive infrared (NDIR) technology, which is characterized by high precision and high stability. The sensor can accurately detect indoor carbon dioxide concentration, evaluate air quality, and dynamically adjust the operating status of the fresh air system according to changes in CO2 concentration.

[0058] The detection limit of the semiconductor TVOC sensor is 0.005 mg / m 3 The detection range of the formaldehyde sensor is 0-3mg / m 3 It can monitor the concentration of volatile organic compounds in the air in real time, and start the air purification device in time when the concentration of harmful gases exceeds the standard, ensuring the health and safety of the indoor air environment.

[0059] Specifically, the control module has a built-in intelligent scheduling algorithm, including:

[0060] A1. The sensor module collects a variety of environmental parameters in real time, including indoor temperature, humidity and air quality parameters, wherein the air quality parameters include CO2 concentration, TVOC concentration, PM2.5 concentration and formaldehyde concentration.

[0061] A2. Compare the current environmental parameters with preset thresholds to determine the degree of deviation of temperature, humidity and air quality parameters; specifically, each environmental parameter has a preset threshold, and the specific threshold is determined according to the indoor conditions.

[0062] A3. Based on the degree of deviation of temperature and humidity, calculate the temperature and humidity joint adjustment amount. The calculation formula is as follows:

[0063] ΔX=λ1×ln(1+|T s -T a |)×tanh(ω1×|H s -H a |)

[0064]

[0065] In the formula, ΔX is the temperature adjustment amount, ΔY is the humidity adjustment amount, T s is the target temperature, T a is the current temperature, H s is the target humidity, H a is the current humidity, λ1 and λ2 are the temperature and humidity adjustment coefficients respectively, ω1 and ω2 are the temperature deviation amplification coefficient and the humidity deviation amplification coefficient respectively, tanh is the hyperbolic tangent function, ln is the natural logarithm function, and e is the exponential function.

[0066] In this embodiment, in the calculation formula of ΔX, ln(1+|T s -T a |) is used to slow down the impact of deviation growth on the adjustment amount and prevent the adjustment amount from increasing excessively when the deviation is large. ω1×|H s -H a | is the amplification process of humidity deviation to ensure that the change of humidity has a moderate impact on the temperature adjustment amount. tanh(ω1×|H s -H a |) is used to smooth the impact of humidity deviation on temperature regulation and avoid nonlinear fluctuations.

[0067] In the calculation formula of ΔY, ln(1+|H s -H a |) is used to mitigate the impact of deviation growth on the adjustment amount and prevent the adjustment amount from increasing excessively when the humidity deviation is large. Used to adjust the humidity regulation according to the square of the temperature deviation, ensuring that the humidity regulation is more sensitive when the temperature deviation is small.

[0068] A4. Based on the calculated ΔX, ΔY values ​​and the degree of deviation of the air quality parameters, the operation mode that the current system should switch or superimpose is comprehensively obtained. The operation modes are divided into: cooling and dehumidification mode, heating and humidification mode, fresh air increment mode and photocatalyst purification mode. The selection logic of the operation mode is as follows:

[0069] Environmental deviation assessment: Based on the specific values ​​of ΔX and ΔY, the urgency and magnitude of temperature and humidity adjustment are assessed.

[0070] Air quality assessment: Analyze the degree of deviation of CO2, TVOC, PM2.5 and formaldehyde concentrations to determine whether it is necessary to start air purification-related operating modes.

[0071] Comprehensive mode decision: Combine the temperature and humidity adjustment requirements with the air quality requirements to comprehensively determine the system operation mode.

[0072] A5. According to the specific values ​​of ΔX, ΔY, and the deviation values ​​of air quality parameters, multi-objective dynamic scheduling instructions are issued to the execution module and the ground radiation control system; when the air quality seriously exceeds the standard, the photocatalyst purification mode is started or strengthened; at the same time, the operating parameters of the cooling and heating device, dehumidification and humidification device, fresh air adjustment device and ground radiation temperature control execution unit are dynamically adjusted to achieve coordinated control of temperature, humidity and air quality.

[0073] Specifically, according to the determination of the operation mode, the control module sends corresponding multi-objective dynamic scheduling instructions to the execution module and the ground radiation control system to achieve coordinated control of each execution device. Specifically including:

[0074] Cooling and heating devices: Adjust the intensity of cooling or heating according to ΔX to control the indoor temperature.

[0078] Through the above multi-objective dynamic scheduling, the system can effectively improve air quality and enhance user comfort and health while ensuring appropriate indoor temperature and humidity. At the same time, the intelligent scheduling algorithm optimizes the system operation status through accurate temperature and humidity adjustment calculation, reduces energy consumption, and improves the efficiency and response speed of the overall system.

Heating mode: When the indoor temperature is lower than the set value, the control module also activates the cooling and heating device, but at this time the refrigerant circulation direction is opposite, releasing heat to the room to increase the indoor temperature. Frequency conversion control: The DC variable frequency fan adjusts the wind speed according to actual needs to achieve precise temperature control and energy-saving operation, avoiding energy waste caused by frequent start and stop.

[0082] Specifically, in one embodiment of the present invention, the dehumidification and humidification device of the execution module adopts a wet film structure and is equipped with an anti-scaling device to slow down the scaling phenomenon.

[0083] In a specific embodiment, the dehumidification and humidification device is composed of an electric heater, a condenser, an evaporator, a humidifier and corresponding control valves. The system uses the same DC variable frequency fan as the refrigeration and heating device to drive the airflow. The execution method is as follows:

[0084] Dehumidification function: When the indoor relative humidity is higher than the set value, the control module starts the dehumidification device, lowers the air temperature through the condenser, condenses and discharges the water, and thus reduces the air humidity. At the same time, the DC variable frequency fan adjusts the wind speed to speed up the dehumidification process. Humidification function: When the indoor relative humidity is lower than the set value, the control module starts the humidification device, releases water vapor into the air through the humidifier, and increases the air humidity.

[0087] Fresh air volume control: According to air quality parameters such as CO2 and TVOC, the control module adjusts the running speed of the fresh air fan and adjusts the fresh air volume through the valve to ensure timely renewal of indoor air and effective dilution of harmful gases. Intelligent adjustment: When air quality parameters exceed the standard, the system automatically increases the fresh air volume to introduce more fresh air to improve indoor air quality; when the air quality is good, the fresh air volume is reduced to save energy. Filtering mechanism: The high-efficiency filtration system in the fresh air conditioning device is regularly cleaned or replaced to maintain filtration efficiency and ensure that the air introduced into the room is clean and pollution-free.

[0088] Specifically, in one embodiment of the present invention, the photocatalyst purification device of the execution module includes a titanium alloy coated photocatalyst plate and a UVA ultraviolet generator with a wavelength of 375nm, and the service life of the photocatalyst plate is not less than 40,000 hours; when the TVOC or formaldehyde concentration exceeds the critical threshold, the control module starts the ultraviolet light source and controls the DC variable frequency fan to introduce air into the photocatalyst plate for photolysis and oxidation reaction to realize the photocatalyst purification mode.

[0089] In a specific embodiment, the photocatalyst purification device is composed of a titanium alloy coated photocatalyst plate, a UVA ultraviolet generator, a fan and a control circuit. The photocatalyst plate uses a high-efficiency photocatalyst material, which can produce a strong redox reaction under ultraviolet light to decompose harmful substances in the air. The execution method is as follows:

[0090] Purification start: When the TVOC or formaldehyde concentration exceeds the set threshold, the control module starts the photocatalyst purification device, and the UVA ultraviolet generator emits ultraviolet light to excite the photocatalyst plate, promoting the decomposition and oxidation of harmful gases. Continuous purification: During the air quality improvement process, the system continuously adjusts the purification intensity according to real-time monitoring data to ensure that the concentration of harmful substances in the indoor air is maintained at a safe level. Circulation ventilation: The fan guides the indoor air to the photocatalyst purification device, and then transports it back to the room after treatment, realizing the circulation and purification of the air and improving the overall air quality.

[0091] The various devices in the execution module work together through the instructions of the control module to achieve the best environmental adjustment effect:

[0110]

[0111] Where P is the real-time power allocation, P base is the reference power, t is the current time, T c is the length of the billing cycle, ζ is the dynamic power adjustment coefficient;

[0112] Among them, when |ΔX+ΔY| is large, the system gives priority to ensuring the power allocation required for indoor temperature and humidity regulation. When |ΔX+ΔY| is small and the air quality does not obviously exceed the standard, it enters the energy-saving operation state.

[0113] In this embodiment, P base It is the power required by the system to maintain basic operation. By multiplying the adjustment factor, the actual power allocation is dynamically adjusted to adapt to different operating requirements and electricity price strategies. ln(1+|ΔX+ΔY|) reflects the combined impact of temperature and humidity regulation requirements.

Reduce power allocation during peak electricity price periods (lower cos values) and increase power allocation during low electricity price periods (higher cos values) to optimize energy costs.

[0114] The specific workflow of the energy management module is as follows:

[0115] The energy monitoring unit continuously monitors the energy consumption of various actuators such as refrigeration and heating devices, dehumidification and humidification devices, fresh air conditioning devices, photocatalyst purification devices and ground radiation control systems, and collects electricity and heat usage data.

[0116] The monitored energy consumption data is transmitted to the data processing and analysis unit through the communication module to ensure the integrity and real-time nature of the data.

[0117] The data processing and analysis unit uses a dynamic power allocation model to conduct in-depth analysis of the collected energy data to identify inefficient links and optimization opportunities in energy use. For example, by analyzing energy consumption patterns in different time periods, corresponding energy-saving measures can be formulated.

[0118] The intelligent dispatch control unit formulates a real-time energy use strategy based on the analysis results and dynamic power allocation model, adjusts the operating status of each actuator in the system, and optimizes power allocation to adapt to the current environmental regulation needs and electricity price changes.
