Description

Technical Field

[0001] This invention belongs to the field of radiant air conditioning system technology, and relates to a radiant environment control system, and more particularly to a radiant environment control system, method, electronic device and storage medium with autonomous exhaust function. Background Technology

[0002] Capillary radiant air conditioning systems are a new type of energy-saving and comfortable air conditioning that can replace conventional central air conditioning. These systems typically use water as the refrigerant, transferring heat through uniform and tightly packed capillary tubes. Because the system requires only a chilled water supply temperature of approximately 14-19℃ in summer and 32-30℃ in winter, lower than the energy consumption of conventional water-cooled air conditioning systems requiring 7℃ in summer and 45-50℃ in winter, the system is more energy-efficient.

[0003] The most common problems with existing capillary radiant air conditioning systems include venting failures and water flow failures, which prevent the entire system from functioning properly. These failures are caused by air easily getting into the capillary network during water injection or replenishment, forming airlocks and affecting hydraulic circulation and heat exchange efficiency. Additionally, existing capillary radiant air conditioning systems are prone to condensation problems.

[0004] Furthermore, capillary radiant air conditioning systems are highly sensitive to humidity. Poor humidity control can affect the normal operation of the entire system, and may even cause it to fail. Especially in the southern climate, humidity can reach over 90% during the rainy season, making it difficult to select suitable fresh air dehumidification equipment in the system design, resulting in poor dehumidification effect and failure to achieve effective dehumidification.

[0005] In view of this, there is an urgent need to design a new capillary radiation system in order to overcome at least some of the aforementioned defects of existing capillary radiation systems. Summary of the Invention

[0006] This invention provides a radiation environment control system, method, electronic device, and storage medium with autonomous exhaust function, which can autonomously exhaust the system to ensure stable operation.

[0007] To solve the above-mentioned technical problems, according to one aspect of the present invention, the following technical solution is adopted: A radiation environment control system with autonomous exhaust function, the radiation environment control system comprising: a cold and heat source device, an air handling device, at least two capillary networks, and a main control module; The cold and heat source devices are connected to the air handling unit and each capillary network through pipelines, and the pipelines are equipped with solenoid valves and pressure sensors; the main control module is connected to the cold and heat source devices, the air handling unit and each solenoid valve. The pressure sensor is used to sense the pressure data in the set pipeline; the main control module obtains the pressure fluctuation data and bubble disturbance signal in the corresponding pipeline based on the pressure change data within the set time interval of the pressure sensor; the main control module controls the operation of the solenoid valve in the corresponding pipeline based on the pressure data sensed by the pressure sensor and the bubble disturbance signal. If the pressure fluctuation data in the pipeline is greater than the set threshold or the bubble disturbance signal meets the set conditions, the main control module controls the solenoid valve of the corresponding pipeline to open for a set time to discharge the gas in the pipeline; the bubble disturbance signal meeting the set conditions includes detecting a set number of continuous bubbles and the interval between adjacent bubbles is within a set time interval, or the number of bubbles detected within a set time interval is less than the set value.

[0008] In one embodiment of the present invention, when the radiation environment control system is started, the main control module controls the solenoid valves of each pipeline to open and close sequentially for a set time to discharge the gas in each pipeline. When the pressure data monitored by the pressure sensor in the corresponding pipeline meets the set conditions and no bubble disturbance signal is detected in the pipeline within the set time, the main control module controls the solenoid valve of the corresponding pipeline to close, thus completing the venting action of the corresponding pipeline. Then, the solenoid valves of the subsequent pipelines are opened, and the venting is completed in accordance with the above process until all pipelines have completed the venting action.

[0009] In one embodiment of the present invention, the return water pipeline of the cold and heat source device is equipped with a check valve or an electric ball valve; the radiation environment control system further includes a water supply pipeline, a water supply valve, a drainage pipeline, and a drainage valve; the water supply valve is installed in the water supply pipeline, and the drainage valve is installed in the drainage pipeline; the two ends of each pipeline are respectively connected to the water supply pipeline and the drainage pipeline; When the radiation environment control system is started, the main control module opens the water supply valve and the drain valve, and controls the solenoid valves of each pipeline to open for a set time and then close, so as to discharge the gas in each pipeline.

[0010] As one embodiment of the present invention, when the system starts running, the tap water supply valve is kept in the open position for a long time; when the water pump is stopped, the control system continuously monitors the pressure sensor reading and bubble disturbance signal. If the pressure fluctuation in any area exceeds the limit or a continuous bubble signal is detected, the solenoid valve of the corresponding area will be opened and forced to vent for a set time (e.g., 30 seconds). After the venting is completed, if the pressure returns to a stable state and the bubble signal disappears, the solenoid valve is closed and the original operating conditions are restored; otherwise, a secondary intervention is triggered—the circulation flushing of the area is started until the bubble signal is completely eliminated and the pressure fluctuation converges to within the threshold. The system automatically records this intervention event and updates the venting parameters of the area for subsequent adaptive optimization.

[0011] All operations support real-time viewing and manual overriding through the HMI interface, and key parameters can be modified through hierarchical authorization in the configuration menu.

[0012] As one embodiment of the present invention, the radiation environment control system further includes an exhaust control mathematical model construction module, which is used to construct an exhaust control mathematical model; The exhaust control mathematical model construction module preprocesses the data in the set training dataset; extracts features from the preprocessed data to identify key features; then combines, statistically analyzes, and groups the extracted key features, standardizes and normalizes the key features to form a key feature combination; the key feature combination includes pressure data sensed by each pressure sensor within a set time period, location data of each pressure sensor, and whether emissions should be emitted; and constructs an exhaust control mathematical model based on the formed key feature combination. The main control module inputs the pressure data sensed by each pressure sensor within a set time period and the position data of each pressure sensor into the exhaust control mathematical model to obtain relevant data on whether to exhaust the pipeline.

[0013] According to another aspect of the present invention, the following technical solution is adopted: an environmental control method for the above-mentioned radiation environment control system with autonomous exhaust function, the environmental control method comprising: The main control module acquires pressure fluctuation data and bubble disturbance signals in the corresponding pipeline based on the pressure change data within a set time interval of the pressure sensor; the main control module controls the operation of the solenoid valve in the corresponding pipeline based on the pressure data sensed by the pressure sensor and the bubble disturbance signals. If the pressure fluctuation data in the pipeline is greater than the set threshold or the bubble disturbance signal meets the set conditions, the main control module controls the solenoid valve of the corresponding pipeline to open for a set time to discharge the gas in the pipeline; the bubble disturbance signal meeting the set conditions includes detecting a set number of continuous bubbles and the interval between adjacent bubbles is within a set time interval, or the number of bubbles detected within a set time interval is less than the set value.

[0014] In one embodiment of the present invention, when the radiation environment control system is started, the main control module controls the solenoid valves of each pipeline to open and close sequentially for a set time to discharge the gas in each pipeline. When the pressure data monitored by the pressure sensor in the corresponding pipeline meets the set conditions and no bubble disturbance signal is detected in the pipeline within the set time, the main control module controls the solenoid valve of the corresponding pipeline to close, thus completing the venting action of the corresponding pipeline. Then, the solenoid valves of the subsequent pipelines are opened, and the venting is completed in accordance with the above process until all pipelines have completed the venting action.

[0015] As one embodiment of the present invention, when the system starts running, the tap water supply valve is kept in the open position for a long time; when the water pump is stopped, the control system continuously monitors the pressure sensor reading and bubble disturbance signal. If the pressure fluctuation in any area exceeds the limit or a continuous bubble signal is detected, the solenoid valve of the corresponding area will be opened and forced to vent for a set time. After the venting is completed, if the pressure returns to a stable state and the bubble signal disappears, the solenoid valve is closed and the original operating conditions are restored; otherwise, a secondary intervention is triggered—the circulation flushing of the area is started until the bubble signal is completely eliminated and the pressure fluctuation converges to within the threshold. The system automatically records this intervention event and updates the venting parameters of the area for subsequent adaptive optimization.

[0016] All operations support real-time viewing and manual overriding through the HMI interface, and key parameters can be modified through hierarchical authorization in the configuration menu.

[0017] As one embodiment of the present invention, the radiation environment control method further includes an exhaust control mathematical model construction step, wherein the exhaust control mathematical model is constructed. In the exhaust control mathematical model construction step, the data in the set training dataset is preprocessed; features are extracted from the preprocessed data to extract key features; then the extracted key features are combined, statistically analyzed, and grouped for coding; the key features are standardized and normalized to form a key feature combination; the key feature combination includes the pressure data sensed by each pressure sensor within a set time period, the position data of each pressure sensor, and whether emissions should be emitted; the exhaust control mathematical model is constructed based on the formed key feature combination. The main control module inputs the pressure data sensed by each pressure sensor within a set time period and the position data of each pressure sensor into the exhaust control mathematical model to obtain relevant data on whether to exhaust the pipeline.

[0018] According to another aspect of the present invention, the following technical solution is adopted: an electronic device, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the steps of the above method.

[0019] According to another aspect of the present invention, the following technical solution is adopted: a storage medium storing computer program instructions thereon, which, when executed by a processor, implement the steps of the above-described method.

[0020] The beneficial effects of the present invention are as follows: The radiation environment control system, method, electronic device and storage medium with autonomous exhaust function proposed in the present invention can autonomously exhaust the system and ensure stable operation of the system.

[0021] In one application scenario of this invention, the cold air handling device of this invention, based on the aforementioned coordinated temperature control of radiant terminals, constructs an integrated control logic of dynamic dew point compensation and multi-terminal linkage adjustment. It collects micro-environmental parameters of various indoor areas in real time through a built-in temperature and humidity sensor array, and combines fuzzy algorithms with PID control based on the differences in thermal response characteristics between the ground and ceiling / wall radiant terminals.

[0022] When the inlet water temperature of the floor coil reaches the set threshold, the system automatically triggers a pre-compensation program. By fine-tuning the inlet water flow and temperature gradient, the floor temperature first enters a stable range. After the floor temperature fluctuation is controlled within ±0.5℃, the adjustment mechanism of the ceiling / wall end is gradually activated. At this point, the indoor reference dew point is calculated based on the stabilized floor temperature data, and the operating parameters of the ceiling / wall are corrected through a secondary compensation algorithm to ensure that the dew point temperature deviation of each radiant surface does not exceed 1℃. This phased and progressive control strategy not only solves the dew point runaway problem caused by asynchronous temperature response of multiple terminals in traditional parallel systems, but also enables the system to maintain stable operation under different building orientations and differences in thermal inertia of the building envelope through adaptive optimization at the algorithm level.

[0031] The term "connection" in the specification includes both direct and indirect connections, such as connections made through active devices, passive devices, or electrical conduction media; it may also include connections made by other active or passive devices that are known to those skilled in the art and can achieve the same or similar functional purpose, such as connections made through circuits or components such as switches or follower circuits.

[0032] This invention discloses a radiation environment control system with autonomous exhaust function. Figure 1 This is a schematic diagram of a radiation environment control system with autonomous exhaust function according to an embodiment of the present invention; please refer to [link / reference]. Figure 1 The radiation environment control system includes: a cold and heat source device 1, an air handling device 2, at least one capillary network, and a main control module 3.

[0033] The cold and heat source device 1 is connected to the air handling device 2 and each capillary network through pipelines. The pipelines are equipped with solenoid valves 4 and pressure sensors 5. The main control module 3 is connected to the cold and heat source device 1, the air handling device 2 and each solenoid valve 4.

[0034] The pressure sensor 5 is used to sense the pressure data in the set pipeline; the main control module 3 obtains the pressure fluctuation data and bubble disturbance signal in the corresponding pipeline based on the pressure change data in the set time interval of the pressure sensor 5; the main control module 3 controls the operation of the solenoid valve 4 in the corresponding pipeline based on the pressure data sensed by the pressure sensor 5 and the bubble disturbance signal.

[0035] If the pressure fluctuation data in the pipeline is greater than the set threshold or the bubble disturbance signal meets the set conditions, the main control module 3 controls the solenoid valve 4 of the corresponding pipeline to open for a set time (5 minutes, or can be set by the user) to discharge the gas in the pipeline; the bubble disturbance signal meeting the set conditions includes detecting a set number of continuous bubbles and the interval between adjacent bubbles is within a set time interval, or the number of bubbles detected within a set time interval is less than the set value.

[0036] In one embodiment of the present invention, when the radiation environment control system is started, the main control module 3 controls the solenoid valves of each pipeline to open and close sequentially for a set time to discharge the gas in each pipeline. When the pressure data monitored by the pressure sensor in the corresponding pipeline meets the set conditions and no bubble disturbance signal is detected in the pipeline within a set time (e.g., 30 seconds), the solenoid valve of the corresponding pipeline is controlled to close to complete the venting action of the corresponding pipeline. Then the solenoid valves of the subsequent pipelines are opened to complete the venting action according to the above process until all pipelines have completed the venting action.

[0037] In one embodiment of the present invention, the return water pipeline of the cold and heat source device is equipped with a check valve 17 or an electric ball valve (or a gas electric valve, solenoid valve); when the return water pipeline is equipped with an electric valve, the electric valve is in the open state when the water pump is working. The radiation environment control system further includes a water supply pipeline, a water supply valve, a drainage pipeline, and a drainage valve; the water supply valve is located on the water supply pipeline, and the drainage valve is located on the drainage pipeline; the two ends of each pipeline are respectively connected to the water supply pipeline and the drainage pipeline.

[0038] When the radiation environment control system is started, the main control module opens the water supply valve and the drain valve, and controls the solenoid valves of each pipeline to open for a set time and then close (duration is 5 minutes, which can be customized) to discharge the gas in each pipeline.

[0039] In one embodiment of the present invention, when the system starts running, the tap water supply valve is kept in the open state for a long time; when the water pump is stopped, the control system continuously monitors the pressure sensor reading (sampling period ≤ 50ms, accuracy ±0.02MPa) and the bubble disturbance signal (spectral analysis bandwidth 2–8kHz, signal-to-noise ratio ≥18dB).

[0040] If the pressure fluctuation in any area exceeds the limit (ΔP > 0.05 MPa / 2s) or a continuous bubble signal is detected (≥3 pulses with an interval ≤ 0.8 seconds), the corresponding area solenoid valve will be opened (response delay ≤ 100 ms) to perform forced venting for 30 seconds.

[0041] After the venting is completed, if the pressure returns to a stable level (ΔP < 0.01 MPa / 2s) and the bubble signal disappears, the solenoid valve is closed and the original operating conditions are restored; otherwise, a secondary intervention is triggered—the circulation flushing of the area is started (flow rate ≥ 1.2 m / s, lasting 60 seconds) until the bubble signal is completely eliminated and the pressure fluctuation converges to within the threshold (ΔP < 0.005 MPa / 2s). The system automatically records this intervention event (including timestamp, area number, pressure curve and spectrum) and updates the venting parameters of the area (such as delay threshold and pulse count tolerance) for subsequent adaptive optimization.

[0042] All operations support real-time viewing and manual overriding on the HMI interface. Key parameters (sampling period, ΔP threshold, pulse interval, etc.) can be modified in the configuration menu with hierarchical authorization (locked by default, requires level 2 permission to unlock).

[0043] In one embodiment of the present invention, the radiation environment control system further includes an exhaust control mathematical model construction module, which is used to construct an exhaust control mathematical model.

[0044] The exhaust control mathematical model construction module preprocesses the data in the set training dataset; extracts features from the preprocessed data to identify key features; then combines, statistically analyzes, and groups the extracted key features, standardizes and normalizes the key features to form a key feature combination; the key feature combination includes pressure data sensed by each pressure sensor within a set time period, location data of each pressure sensor, and whether emissions should be emitted; and constructs an exhaust control mathematical model based on the formed key feature combination.

[0045] The main control module 3 inputs the pressure data sensed by each pressure sensor within a set time period and the position data of each pressure sensor into the exhaust control mathematical model to obtain relevant data on whether to exhaust the pipeline.

[0046] In one embodiment of the present invention, the radiation environment control system further includes a sensor assembly 6; the sensor assembly 6 includes at least a first temperature sensing unit, at least a second temperature sensing unit, at least a third temperature sensing unit, at least a humidity sensing unit, and at least a carbon dioxide sensing unit.

[0047] Each first temperature sensing unit is used to sense and set temperature data for a set area inside the building; each second temperature sensing unit is used to sense and set temperature data for a set area outside the building; each third temperature sensing unit is used to sense the return water temperature data of the cold and heat source device; each humidity sensing unit is used to sense and set humidity data for a set area inside the building; and each carbon dioxide sensing unit is used to sense and set carbon dioxide concentration data for a set area inside the building.

[0048] The main control module 3 is connected to the heat source device 1, the air handling device 2, and the sensor assembly 6 respectively. The main control module 3 controls the heat source device 1, the air handling device 2, and the valves based on the data sensed by the sensor assembly 6.

[0049] In one embodiment of the present invention, at least one capillary network includes a first capillary network 7 and a second capillary network 8; the heat source device 1 is connected to the air handling device 2 through a first input pipe 9 and a first output pipe 10; the heat source device 1 is connected to the first capillary network 7 through a second input pipe 11 and a second output pipe 12; and the heat source device 1 is connected to the second capillary network 8 through a third input pipe 13 and a third output pipe 14.

[0050] Figure 2 This is a schematic diagram of the control section of a radiation environment control system with autonomous exhaust function in one embodiment of the present invention; please refer to [link / reference]. Figure 2In one embodiment of the present invention, the main control module 6 includes a personnel density assessment module 61 and a dew point temperature compensation module 62. The personnel density assessment module is used to assess the personnel density and distribution data within a set building based on data sensed by each carbon dioxide sensor unit using a dynamic fuzzy algorithm for carbon dioxide data. The dew point temperature compensation module is used to compensate the dew point temperature data in real time based on the real-time data sensed by the sensor components, obtaining compensated dew point temperature data. The main control module controls the outlet water temperature of the cold and heat source device based on the compensated dew point temperature data obtained by the dew point temperature compensation module.

[0051] The sensor assembly 6 further includes at least one pressure sensing unit, which is disposed in a designated area of ​​the first capillary network and / or the second capillary network to sense pressure data of the designated pipeline of the first capillary network and / or the second capillary network.

[0052] The main control module 3 further includes a water flow disturbance noise removal module 63, which removes water flow disturbance noise based on the pressure data sensed by each pressure sensing unit using a Kalman filter algorithm. The dew point temperature compensation module further compensates the dew point temperature data by combining the data after the water flow disturbance noise removal module removes the water flow disturbance noise, and obtains the compensated dew point temperature data.

[0053] The radiation environment control system further includes a dew point temperature mathematical model construction module, which is used to construct a dew point temperature mathematical model. The dew point temperature mathematical model construction module preprocesses the data in a set training dataset; extracts features from the preprocessed data to identify key features; then combines, statistically analyzes, and groups the extracted key features, standardizing and normalizing them to form a key feature combination. This key feature combination includes temperature data acquired by each first temperature sensing unit, temperature data acquired by each second temperature sensing unit, temperature data acquired by each third temperature sensing unit, humidity data acquired by each humidity sensing unit, pressure data acquired by each pressure sensing unit, carbon dioxide concentration data acquired by each carbon dioxide sensing unit, location data of each sensing unit, building space data, layout data of the first capillary network, layout data of the second capillary network, personnel density data and distribution data, and dew point temperature data. A dew point temperature mathematical model is constructed based on the formed key feature combination. The dew point temperature compensation module acquires dew point temperature data based on the dew point temperature mathematical model constructed by the dew point temperature mathematical model construction module.

[0054] In one application scenario of the present invention, when the system is working in cold radiation mode, the intelligent cold and heat source device automatically outputs dew point water temperature. The first valve 15 of the output pipeline of the air handling unit 2 is closed, and the second valve 16 of the output pipeline of the first capillary network 7 and the second capillary network 8 is opened. The dew point water temperature output by the intelligent cold and heat source device simultaneously enters the ground capillary and the top capillary, and after being output, they converge and return to the main unit (intelligent cold and heat source device) through the second valve 14.

[0055] When the system is operating in automatic dehumidification mode, the intelligent cold and heat source equipment automatically outputs 7°C cold water; the first valve 15 of the output pipeline of the air handling unit 2 is opened, and the second valve 16 of the output pipeline of the first capillary network 7 and the second capillary network 8 is closed; the intelligent cold and heat source equipment outputs 7°C water, which passes through the air handling unit 2 and the first valve 13 and then returns to the main unit (intelligent cold and heat source equipment).

[0056] When the system is operating in automatic fresh air mode, the intelligent cold and heat source equipment is not working, the first valve 15 of the output pipeline of the air handling unit 2 is closed, and the second valve 16 of the output pipeline of the first capillary network 7 and the second capillary network 8 is closed; other equipment except for the fresh air handling equipment is not working.

[0057] When the system is operating in manual thermal radiation mode, the intelligent cold and heat source equipment is forced to set a higher temperature (e.g., 28~35℃); the first valve 15 of the output pipeline of the air handling unit 2 is closed, and the second valve 16 of the output pipeline of the first capillary network 7 and the second capillary network 8 is open; the outlet water temperature of the intelligent cold and heat source equipment is customized (28~35℃), and returns to the main unit through the second valve 16.

[0058] In one application scenario of this invention, the tap water valve is opened after the project is powered on and before the system runs. At the same time, the main control module starts self-testing to determine the capillary ends of several areas. Then, the main control panel is pressed with one key to sequentially open and close the area solenoid valves one by one to vent the air until the end (the venting interval can be set arbitrarily). This solves the problem of difficult venting debugging in steady-state radiation control systems.

[0059] During operation, the radiant system generates air bubbles, frequently causing water flow malfunctions and system shutdowns. To address the frequent air problems in the system's pipelines or when water flow malfunctions occur and the water pump stops working, the main control module controls the operation of the solenoid valves in the corresponding pipelines. The tap water's own pressure forces the capillary radiant end (because there is a one-way valve, the tap water can only flow in one direction), and the water and air are automatically discharged through the automatic air vent valve. The water flow switch closes, and the main control module resumes normal operation.

[0060] This invention further discloses an environmental control method for the above-mentioned radiation environment control system with autonomous exhaust function. Figure 3 This is a flowchart of an environmental control method according to an embodiment of the present invention; please refer to [link / reference]. Figure 3 The environmental control method includes:

Step S1

[0061]

Step S2

[0062] If the pressure fluctuation data in the pipeline exceeds the set threshold or the bubble disturbance signal meets the set conditions, the main control module controls the solenoid valve of the corresponding pipeline to open for a set time (5 minutes, or can be set manually) to discharge the gas in the pipeline; the bubble disturbance signal meeting the set conditions includes detecting a set number of continuous bubbles and the interval between adjacent bubbles is within a set time interval, or the number of bubbles detected within a set time interval is less than the set value.

[0063] In one embodiment of the present invention, when the radiation environment control system is started, the main control module controls the solenoid valves of each pipeline to open and close sequentially for a set time to discharge the gas in each pipeline. When the pressure data monitored by the pressure sensor in the corresponding pipeline meets the set conditions and no bubble disturbance signal is detected in the pipeline within a set time (e.g., 30 seconds), the solenoid valve of the corresponding pipeline is controlled to close to complete the venting action of the corresponding pipeline. Then the solenoid valves of the subsequent pipelines are opened to complete the venting action according to the above process until all pipelines have completed the venting action.

[0064] In one embodiment of the present invention, when the system starts running, the tap water supply valve needs to be kept in the open state for a long time; when the water pump is stopped, the control system continuously monitors the pressure sensor reading (sampling period ≤ 50ms, accuracy ±0.02MPa) and the bubble disturbance signal (spectral analysis bandwidth 2–8kHz, signal-to-noise ratio ≥18dB). If the pressure fluctuation in any area exceeds the limit (ΔP > 0.05MPa / 2s) or a continuous bubble signal is detected (≥3 pulses, interval ≤ 0.8 seconds), the corresponding area solenoid valve should be opened (response delay ≤ 100ms) to perform forced venting for 30 seconds. After the venting is completed, if the pressure returns to a stable level (ΔP < 0.01 MPa / 2s) and the bubble signal disappears, the solenoid valve is closed and the original operating conditions are restored; otherwise, a secondary intervention is triggered—the circulation flushing of the area is started (flow rate ≥ 1.2 m / s, lasting 60 seconds) until the bubble signal is completely eliminated and the pressure fluctuation converges to within the threshold (ΔP < 0.005 MPa / 2s). The system automatically records this intervention event (including timestamp, area number, pressure curve and spectrum) and updates the venting parameters of the area (such as delay threshold and pulse count tolerance) for subsequent adaptive optimization.

[0065] All operations support real-time viewing and manual overriding on the HMI interface. Key parameters (sampling period, ΔP threshold, pulse interval, etc.) can be modified in the configuration menu with hierarchical authorization (locked by default, requires level 2 permission to unlock).

[0066] In one application scenario of this invention, before system debugging, the tap water valve and drain valve are opened, and then the one-button air release button is pressed. The solenoid valves in each zone open and close sequentially for 5 minutes (customizable), allowing the tap water to purge air from all zones. The system pressure sensor monitors the pressure changes in each zone's pipeline in real time. When the pressure in a zone reaches a preset threshold and the water flow switch remains free of air bubbles for 30 seconds, the control system automatically closes the solenoid valve in that zone and switches to the next zone. After air release is completed in all zones, the water supply valve automatically closes, the drain valve simultaneously cuts off the water flow, and the system enters a pressure-holding state, completing the one-button air release function.

[0067] In one embodiment of the present invention, the radiation environment control method further includes an exhaust control mathematical model construction step, wherein the exhaust control mathematical model is constructed.

[0068] In the exhaust control mathematical model construction step, the data in the set training dataset is preprocessed; features are extracted from the preprocessed data to extract key features; then the extracted key features are combined, statistically analyzed, grouped and coded, and standardized and normalized to form a key feature combination; the key feature combination includes the pressure data sensed by each pressure sensor within a set time period, the position data of each pressure sensor, and whether emissions should be emitted; the exhaust control mathematical model is constructed based on the formed key feature combination.

[0069] The main control module inputs the pressure data sensed by each pressure sensor within a set time period and the position data of each pressure sensor into the exhaust control mathematical model to obtain relevant data on whether to exhaust the pipeline.

[0070] The radiation environment control method further includes a dew point temperature mathematical model construction step, which involves constructing a dew point temperature mathematical model. This step includes: preprocessing data from a set training dataset; extracting features from the preprocessed data to identify key features; then combining, statistically analyzing, and grouping the extracted key features; standardizing and normalizing the key features to form a key feature combination. This key feature combination includes temperature data acquired by each first temperature sensing unit, temperature data acquired by each second temperature sensing unit, temperature data acquired by each third temperature sensing unit, humidity data acquired by each humidity sensing unit, pressure data acquired by each pressure sensing unit, carbon dioxide concentration data acquired by each carbon dioxide sensing unit, location data of each sensing unit, building space data, layout data of the first capillary network, layout data of the second capillary network, personnel density data and distribution data, and dew point temperature data. A dew point temperature mathematical model is constructed based on the formed key feature combination. Dew point temperature data is then obtained based on the dew point temperature mathematical model constructed by the dew point temperature mathematical model construction module.

[0071] This invention also discloses an electronic device, Figure 4 This is a schematic diagram of the composition of an electronic device according to an embodiment of the present invention; please refer to [link / reference]. Figure 4 At the hardware level, the electronic device includes a memory, a processor, and at least one communication interface; the processor may be a microprocessor, and the memory may include main memory, such as random access memory (RAM) or non-volatile memory. Of course, the electronic device may also include other hardware as needed.

[0072] The processor, communication interface, and memory can be interconnected via an internal bus.

[0074] This invention further discloses a storage medium storing computer program instructions, which, when executed by a processor, implement the following steps of the method of this invention (e.g. Figure 3 (as shown) The main control module acquires pressure fluctuation data and bubble disturbance signals in the corresponding pipeline based on the pressure change data within a set time interval of the pressure sensor; the main control module controls the operation of the solenoid valve in the corresponding pipeline based on the pressure data sensed by the pressure sensor and the bubble disturbance signals.

[0075] In summary, the radiation environment control system, method, electronic device, and storage medium with autonomous exhaust function proposed in this invention can autonomously exhaust the system, ensuring stable system operation.

[0076] In one application scenario of this invention, the cold air handling device of this invention, based on the aforementioned coordinated temperature control of radiant terminals, constructs an integrated control logic of dynamic dew point compensation and multi-terminal linkage adjustment. It collects micro-environmental parameters of various indoor areas in real time through a built-in temperature and humidity sensor array, and combines fuzzy algorithms with PID control based on the differences in thermal response characteristics between the ground and ceiling / wall radiant terminals.

[0077] When the inlet water temperature of the floor coil reaches the set threshold, the system automatically triggers a pre-compensation program. By fine-tuning the inlet water flow and temperature gradient, the floor temperature first enters a stable range. After the floor temperature fluctuation is controlled within ±0.5℃, the adjustment mechanism of the ceiling / wall end is gradually activated. At this point, the indoor reference dew point is calculated based on the stabilized floor temperature data, and the operating parameters of the ceiling / wall are corrected through a secondary compensation algorithm to ensure that the dew point temperature deviation of each radiant surface does not exceed 1℃. This phased and progressive control strategy not only solves the dew point runaway problem caused by asynchronous temperature response of multiple terminals in traditional parallel systems, but also enables the system to maintain stable operation under different building orientations and differences in thermal inertia of the building envelope through adaptive optimization at the algorithm level.
