Description

Technical Field

[0001] This application relates to the field of intelligent control, and in particular to an intelligent operation control method and system for steam air conditioning based on environmental perception. Background Technology

[0002] Steam air conditioners utilize the latent heat of phase change released during the transformation of water from a liquid to a gaseous state to regulate indoor temperature. However, in actual operation, the process of water transforming into steam involves volume expansion and a change in physical state, resulting in an inherent thermal hysteresis effect. When the indoor temperature rises to the user-set target value and the control system commands the heating to stop, the steam generator remains at a high temperature. Furthermore, the high-temperature water at the boiling point inside the chamber continues to flash evaporate under pressure changes, generating a large amount of gaseous steam. This causes the indoor temperature to continue rising after reaching the set point, reducing the accuracy of temperature control.

[0003] To mitigate the temperature overshoot caused by thermal hysteresis, related technologies typically employ a proportional-integral-derivative (PID) control algorithm combined with pulse width modulation (PWM) to regulate heating power. This method detects the difference between the indoor air temperature and the set temperature in real time. When the indoor temperature approaches the set value, it proportionally reduces the output power of the heating element or adjusts the duty cycle. By slowing down the heating rate, it reduces the heat supply required to reach the target temperature, aiming to allow the temperature curve to transition more smoothly to the set value and remain constant.

[0004] However, for instantaneous steam air conditioners, linear power regulation based on temperature deviation has limitations in the low-load maintenance phase. The steam generator needs to be maintained above the minimum boiling power to ensure continuous steam output, but this minimum boiling power is often higher than the low heat load required to maintain a constant indoor temperature. This makes it difficult for related technical solutions to maintain a balance between the continuity of steam generation and indoor heat when outputting low power to maintain room temperature. This can easily cause the indoor temperature to fluctuate between overheating and undercooling due to shutdown, affecting the energy efficiency performance of the steam air conditioner and the user's comfort during the constant temperature phase. Summary of the Invention

[0005] This application provides a method and system for intelligent operation control of steam air conditioning based on environmental perception, which can improve the effectiveness and continuity of steam generation under low load.

[0006] In a first aspect, this application provides an intelligent operation control method for steam air conditioning based on environmental perception, applied to a steam generator control system, comprising: real-time acquisition of the target temperature value, indoor temperature value, and the cavity water temperature value and cavity water capacity of the steam generator; based on the cavity water temperature value and cavity water capacity, calculating the dynamic cutoff threshold of the thermal hysteresis effect after cutting off the heating power at the current moment; when the indoor temperature value reaches the dynamic cutoff threshold, generating a stop heating command to cut off the heating power input of the steam generator, so that the residual phase change heat released in the steam generator drives the indoor temperature value to inertially approach the target temperature value; after cutting off the heating power input, acquiring the indoor environmental heat dissipation rate at the current moment; using the minimum boiling power required for the steam generator to generate continuous and effective steam as a benchmark, calculating the heating duty cycle within a unit control cycle based on the environmental heat dissipation rate; and controlling the steam generator to periodically switch between turning on the minimum boiling power and stopping heating based on the heating duty cycle.

[0007] By adopting the above technical solution, the steam generator control system (hereinafter referred to as the control system) first monitors the dynamic cutoff threshold of the steam generator during the heating stage in real time, cuts off the heating power in advance, and uses the remaining phase change heat of the high-temperature water in the cavity to drive the room temperature to the target value, eliminating the temperature overshoot caused by thermal hysteresis in traditional temperature control. Secondly, during the constant temperature maintenance stage, the control system calculates the heating duty cycle required to offset the current indoor heat dissipation rate by using the minimum boiling power of the steam generator to produce continuous steam, thereby controlling the steam generator to switch between the optimal boiling state and the stop state. In summary, this solution achieves precise temperature rise endpoint control by utilizing thermal inertia, and improves the constant temperature stability under low indoor heat loads by using intermittent pulse heating based on physical characteristics, while ensuring the continuity of steam quality.

[0008] In conjunction with some embodiments of the first aspect, in some embodiments, based on the water temperature and water volume inside the cavity, the dynamic cutoff threshold of the thermal hysteresis effect after the heating power is cut off at the current moment is calculated. Specifically, this includes: based on the water temperature and water volume inside the cavity, calculating the remaining phase change heat released in the steam generator after the heating power is cut off at the current moment; based on the indoor temperature and a preset spatial heat conversion coefficient, calculating the temperature rise that can be caused by the remaining phase change energy being released into the indoor environment, and obtaining a predicted temperature rise value; subtracting the predicted temperature rise value from the target temperature value to calculate the dynamic cutoff threshold.

[0009] By employing the above technical solution, the control system calculates the total remaining heat contributed by sensible heat release and pressure change flash evaporation after a power outage, based on the real-time water temperature and volume within the cavity. Secondly, by introducing a spatial heat conversion coefficient, the control system numerically converts this remaining internal energy into a predicted temperature rise for a specific indoor space, thus determining the current dynamic cutoff threshold. In summary, this solution transforms the fuzzy effects of thermal inertia into precise mathematical control boundaries, ensuring that after heating stops, the remaining heat is just enough to raise the room temperature to the set target, avoiding energy waste and decreased comfort.

[0010] In conjunction with some embodiments of the first aspect, in some embodiments, before calculating the dynamic cutoff threshold by subtracting the predicted temperature rise value from the target temperature value, the method further includes: obtaining current indoor biological distribution characteristic parameters, which at least include the number of people and the distance weight between each person and the steam air conditioner outlet; mapping the indoor biological distribution characteristic parameters to the biological thermal gain value of the current environment based on a preset biological thermal metabolism model and distance weights; calculating a thermal compensation correction amount for the target temperature value based on the biological thermal gain value; subtracting the thermal compensation correction amount from the target temperature value to obtain the corrected target temperature value, and using the corrected target temperature value as the reference value in the step of calculating the dynamic cutoff threshold.

[0011] By adopting the above technical solution, the control system further considers the biothermal effect of indoor occupants during temperature balance control. First, the control system identifies the number of people and their distance weight from the air outlet, quantifies the biothermal gain value in the current environment, and further converts it into a corresponding thermal compensation correction. Then, the control system corrects the target temperature value (baseline value) based on the thermal compensation correction and calculates the cutoff threshold based on the corrected target temperature value. In summary, this solution identifies and utilizes the auxiliary heat emitted by biological organisms, avoiding localized overheating caused by excessive mechanical heat source output in crowded or close-range airflow scenarios, further improving the perceived thermal comfort of humans and the environmental adaptability of the control system.

[0012] In conjunction with some embodiments of the first aspect, in some embodiments, after cutting off the heating power input, the current indoor ambient heat dissipation rate is obtained, specifically including: after cutting off the heating power input, continuously monitoring the rate of decrease of the indoor temperature value over time; calculating the amount of heat replenishment per unit time required to maintain the current indoor temperature based on the rate of decrease, and obtaining the ambient heat dissipation rate.

[0013] By employing the above technical solution, the control system continuously tracks the trajectory of indoor temperature decrease over time, extracts the temperature drop slope characterizing the current room insulation performance and the impact of the indoor-outdoor temperature difference, and, combined with indoor space parameters, calculates the amount of heat supply required per unit time to maintain the current temperature balance, thus obtaining the environmental heat dissipation rate at each moment. This solution eliminates the need for additional, expensive heat flux sensors to perceive dynamic changes in the room's heat load in real time, improving the solution's economy and the robustness of temperature control.

[0014] In conjunction with some embodiments of the first aspect, in some embodiments, the heating duty cycle within a unit control cycle is calculated based on the minimum boiling power required for the steam generator to generate continuous and effective steam, according to the ambient heat dissipation rate. Specifically, this includes: determining the target circulating air volume for uniformly diffusing heat to the indoor space within a unit control cycle based on the ambient heat dissipation rate; obtaining the effective heat transfer coefficient of the steam generator when operating at minimum boiling power and exchanging heat with the target circulating air volume; weighting the minimum boiling power using the effective heat transfer coefficient to obtain the effective output power of the steam generator under the current operating conditions; and calculating the ratio of the ambient heat dissipation rate to the effective output power, using the ratio as the heating duty cycle of the steam generator within a unit control cycle.

[0015] By adopting the above technical solution, the control system determines the target air volume based on environmental requirements and obtains the effective heat transfer coefficient of the steam generator under minimum boiling power operation, thereby calculating the actual effective output power injected into the environment. Secondly, the control system compares the environmental heat dissipation rate with this effective output power to calculate the time ratio for maintaining thermal equilibrium, thus obtaining the heating duty cycle. In summary, this solution ensures that the average heat output of the control system is strictly equal to the heat loss of the environment within each control cycle, maintaining the boiling condition of the steam generator while achieving constant temperature control under low load.

[0016] In conjunction with some embodiments of the first aspect, in some embodiments, a target circulating air volume for uniformly diffusing heat to the indoor space within a unit control cycle is determined based on the ambient heat dissipation rate. Specifically, this includes: calculating the heat balance air volume required to offset the ambient heat dissipation rate based on air specific heat capacity and air density parameters, as the target circulating air volume.

[0017] By adopting the above technical solution, this solution starts from the characteristics of the energy transfer medium, ensuring that the circulating air volume is just enough to carry and transport the required replenishment heat, avoiding the discomfort caused by excessive air volume or the heat accumulation caused by insufficient air volume, and achieving a dynamic balance of the air-heat flow field.

[0018] In conjunction with some embodiments of the first aspect, in some embodiments, after calculating the ratio of the ambient heat dissipation rate to the effective output power and using the ratio as the heating duty cycle of the steam generator in a unit control cycle, the method further includes: monitoring the time difference between the steam generator starting at minimum boiling power and actually generating phase change steam flow to obtain the phase change response hysteresis duration; and superimposing the phase change response hysteresis duration onto the theoretical heating duration calculated based on the heating duty cycle to obtain the corrected actual heating duration.

[0019] By adopting the above technical solution, the control system quantifies the physical lag time from water heat absorption to the phase change point, and adds this lag time to the theoretically calculated heating time to generate the corrected actual heating time. In summary, this solution compensates for the ineffective preheating time in the initial heating stage, ensuring that the effective time for actually releasing steam heat into the room strictly conforms to the theoretical duty cycle required to maintain a constant temperature in each control cycle, thus eliminating the insufficient heating deviation caused by the phase change delay.

[0020] In conjunction with some embodiments of the first aspect, in some embodiments, the steam generator is controlled to periodically switch between activating minimum boiling power and stopping heating according to the heating duty cycle. Specifically, this includes: activating the heating power input of the steam generator at the start of a unit control cycle; starting a timer to monitor the heating duration, and cutting off the heating power input when the heating duration reaches the actual heating time; and maintaining the stopped heating state for the remaining time of the unit control cycle until the start of the next unit control cycle.

[0021] By adopting the above technical solution, the control system transforms continuous energy demand into discrete time-slice control, solving the problem of steady-state operation of instantaneous heating equipment under low load. First, the control system ensures the steam generator operates at minimum boiling power during the start-up phase within a unit control cycle, guaranteeing the stability of phase change. Second, through high-precision timer monitoring, the system strictly adheres to the actual heating time after hysteresis correction. Finally, it remains off for the remaining time, avoiding grid impact or equipment damage caused by frequent start-ups and shutdowns. In summary, this solution, through a time modulation strategy, ensures the steam generator always operates within its optimal efficiency range while achieving smooth regulation of minute indoor temperature differences.

[0022] In conjunction with some embodiments of the first aspect, in some embodiments, during the process of controlling the steam generator to periodically switch between activating minimum boiling power and stopping heating according to the heating duty cycle, the method further includes: controlling the fan of the steam air conditioner to execute a preset anti-cold air micro-circulation speed during the phase change response hysteresis period, wherein the anti-cold air micro-circulation speed is less than the speed corresponding to the target circulation air volume; when the phase change response hysteresis period is detected to end and steam begins to be released, controlling the fan to switch from the anti-cold air micro-circulation speed to the speed corresponding to the target circulation air volume.

[0023] By adopting the above technical solution, firstly, during the preheating stage where a phase change response hysteresis is confirmed, the control system actively limits the fan speed to a micro-circulation state to prevent cold air from entering. This state maintains airflow within the unit for accurate sensor sampling while preventing unheated high-speed airflow from directly blowing onto the user. Secondly, when the critical point of the hysteresis ending and steam release beginning is detected, the control system switches the fan to the target circulation airflow, ensuring that high-temperature steam is quickly carried out and mixed with indoor air. In summary, this solution achieves time-series linkage between fan operation and steam generation, avoiding time misalignment between airflow and heat output, thereby improving user comfort during the temperature control transition phase.

[0024] In a second aspect, this application provides a steam generator control system, which includes: one or more processors and a memory; the memory is coupled to one or more processors, the memory is used to store computer program code, the computer program code includes computer instructions, and the one or more processors invoke the computer instructions to cause the steam generator control system to be as described in the first aspect and any possible implementation thereof.

[0025] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0026] 1. By adopting a control strategy based on the dynamic cutoff threshold of thermal hysteresis calculated from the water state in the cavity and the heating duty cycle determined based on the ambient heat dissipation rate, the control system can accurately quantify the remaining phase change heat energy released in the steam generator before heating is cut off. This thermal inertia drives the room temperature to glide to the target value, and intermittent pulse heating is performed based on the minimum boiling power during the constant temperature stage. This effectively solves the problem of indoor temperature overshoot caused by the thermal hysteresis of steam phase change in related technologies, as well as the technical problem that traditional linear power regulation cannot maintain continuous and effective steam generation under low load. This achieves precise control of indoor temperature without overshoot, while ensuring that high-quality continuous steam can be output even during the low heat load maintenance stage, thus improving the energy efficiency and temperature control stability of the steam air conditioner.

[0027] 2. By adopting a bio-thermal gain mapping and target temperature thermal compensation correction mechanism based on indoor biological distribution characteristic parameters, the control system can incorporate the human body as an auxiliary heat source into the temperature control model. It automatically calculates and deducts the corresponding thermal compensation amount according to the personnel density and distance from the air outlet, and dynamically adjusts the target temperature benchmark. This achieves more humanized and intelligent temperature control that meets actual physical needs, avoids excessive energy supply in densely populated scenarios, optimizes equipment operating energy consumption, and improves the thermal comfort experience of users in variable environments.

[0028] 3. By adopting a phased fan control strategy that executes the anti-cold air micro-circulation speed during the phase change response lag time and switches to the target circulation air volume after detecting steam release, the control system restricts airflow output during the preheating stage before steam is generated to maintain the sampling of the internal microenvironment without causing a perceived draft. The main air supply is only started synchronously after the effective steam flow is formed. This effectively solves the problem of unheated cold air being blown into the room due to the asynchronous operation of the fan and steam generator in the initial stage of instant heating or periodic heating switching, which causes discomfort to users. This achieves precise synchronization of air and heat output and improves the user's comfort during the transition phase of steam air conditioning heating. Attached Figure Description

[0032] The terminology used in the following embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. As used in the specification of this application, the singular expressions “a,” “an,” “the,” “the,” and “this” are intended to include the plural expressions as well, unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used in this application refers to any or all possible combinations including one or more of the listed items.

[0033] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature, and in the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more.

[0034] This application provides a method for intelligent operation control of steam air conditioning based on environmental perception.

[0035] In related technologies, feedback control of indoor temperature can be achieved by using PID algorithms in conjunction with linear power regulation. Traditional control logic relies on real-time temperature difference to adjust heating power. However, in steam air conditioning applications, the phase change process of water has a significant thermal hysteresis effect, causing the high-temperature water in the cavity to continue flashing and generating steam after heating stops, resulting in the indoor temperature exceeding the set value (i.e., temperature overshoot). In addition, during low-load phases where only room temperature needs to be maintained, the linear reduction of power to match low heat demand often causes the equipment to operate below the boiling point, resulting in steam output interruption and frequent fluctuations in indoor temperature between undercooling and overheating.

[0036] The present application uses the dynamic cutoff threshold of the thermal hysteresis effect after cutting off the heating power at the current moment and the heating duty cycle calculated based on the ambient heat dissipation rate. By using the heat released by the remaining phase change to drive the indoor temperature value to inertially approach the target temperature value, and periodically switching based on the minimum boiling power, the precise control of temperature is achieved to meet the balance of heat supply and demand, and the effectiveness and continuity of steam generation under low load are improved.

[0037] As can be seen, by adopting the dynamic cutoff threshold determination and duty cycle control strategy based on minimum boiling power in the embodiments of this application, while achieving precise temperature control by utilizing the thermal hysteresis effect, it can also solve the problem of steam output interruption and temperature fluctuation caused by insufficient power in traditional linear control under low heat load, thereby realizing efficient, stable and comfortable intelligent operation of steam air conditioning.

[0038] In addition, the key structures in the embodiments of this application are explained, including:

[0039] A steam air conditioner is a temperature regulation device based on a water circulation system, including a hot water tank, a steam generator, heat exchange copper pipes, a fan, and a return water pipe. It provides heating by releasing latent heat through steam condensation.

[0040] A steam generator is the core component of a steam air conditioner, used to heat water to a boiling point to produce high-temperature steam and release heat. Essentially, a steam generator is a heater, and its types include electric heating, natural gas heating, and electromagnetic heating.

[0041] To facilitate understanding, the method provided in this implementation will be described in detail below, using the above scenario as an example. Please refer to [link / reference]. Figure 1 This is a flowchart illustrating an intelligent operation control method for steam air conditioning based on environmental perception, as described in an embodiment of this application.

[0042] S101. Real-time acquisition of target temperature value of indoor environment, indoor temperature value, water temperature value inside steam generator cavity, and water capacity inside steam generator cavity;

[0043] Among them, the indoor environment refers to the target enclosed space that needs to be regulated by steam air conditioning, such as a residential room or office area; the target temperature value refers to the user-preset or system-generated desired indoor temperature standard based on a comfort algorithm, such as 26℃; the indoor temperature value is used to represent the current indoor ambient air temperature collected in real time by a temperature sensor; the water temperature value inside the steam generator refers to the real-time temperature of the water medium inside the heating chamber of the steam generator detected by a built-in temperature probe; the water capacity inside the chamber is used to represent the actual amount of water stored in the heating chamber of the steam generator at the current moment, which is obtained by real-time detection by a liquid level sensor or by calculation of the inflow and outflow of water.

[0044] This step is performed periodically after the steam generator control system (hereinafter referred to as the control system) is started and in operation, aiming to provide real-time data support for subsequent precise temperature control. Specifically, the control system establishes communication connections with ambient temperature sensors distributed indoors, temperature sensors inside the steam generator, and liquid level detection devices through a signal transmission interface. The control system reads the current indoor temperature, water temperature, and water volume in the chamber in real time according to a preset sampling frequency (e.g., once per second), while simultaneously retrieving the set target temperature value from memory or the user interface. The control system performs analog-to-digital conversion and filtering on the collected multi-source data, converting it into digital signals that can be used for logical operations.

[0045] Optionally, in some embodiments, the control system can also perform intelligent water replenishment adjustment based on the water volume inside the steam generator cavity. Specifically, this includes: after acquiring the water volume inside the cavity, comparing it with a preset minimum boiling maintenance water level; if the water volume inside the cavity is lower than the minimum boiling maintenance water level, calculating the theoretical water consumption required to generate steam in the next unit control cycle based on the minimum boiling power and a preset unit control cycle duration; obtaining the target water replenishment amount by summing the difference between the minimum boiling maintenance water level and the current water volume inside the cavity with the theoretical water consumption; generating a water replenishment command to control the water inlet actuator to open, injecting the target water replenishment amount into the steam generator to ensure that the water volume inside the cavity remains within the range required to meet continuous phase change during subsequent calculations.

[0046] S102. Based on the water temperature and water volume inside the cavity, calculate the dynamic cutoff threshold of the thermal hysteresis effect after the heating power is cut off at the current moment.

[0047] The thermal hysteresis effect refers to the physical phenomenon that after the power to the steam generator is cut off, the water in the heating chamber, which is already at a high temperature or boiling state, continues to undergo phase change to produce steam by relying on its own accumulated heat energy, causing the indoor temperature to continue to rise after the power is cut off. The dynamic cutoff threshold represents the critical value of the indoor temperature at which the control system should execute the stop heating operation in order to counteract the thermal hysteresis effect. This threshold is usually lower than the target temperature value.

[0048] This step is executed immediately upon obtaining the latest real-time data to predict the impact of thermal inertia on temperature control. Specifically, based on the real-time acquired water temperature and volume within the cavity, the control system uses a thermodynamic model to calculate the total heat (including sensible heat and latent heat of vaporization) that the remaining water in the heating cavity can release after power is cut off. Next, the control system, considering parameters such as the indoor space volume and air specific heat capacity, estimates the temperature rise that would result from the complete release of this remaining heat into the room. Finally, the control system subtracts this temperature rise from the target temperature value to obtain the dynamic cutoff threshold for the current moment.

[0049] S103. When the indoor temperature value reaches the dynamic cutoff threshold, a stop heating command is generated to cut off the heating power input of the steam generator, so that the remaining phase change heat released in the steam generator drives the indoor temperature value to inertially approach the target temperature value.

[0050] Among them, the stop heating command indicates that the control system sends a power-off command signal to the heating control module of the steam generator; the heating power input refers to the electrical power supplied to the heating element (such as an electric heating tube) of the steam generator; the residual phase change is used to indicate the physical process of cutting off the continued vaporization of water that is close to or has reached the boiling point in the heating chamber after heating.

[0051] This step continuously monitors the indoor temperature during the heating phase and executes when a trigger condition is met. Specifically, the control system compares the real-time indoor temperature value with the dynamic cutoff threshold calculated for this control cycle. When the indoor temperature value is greater than or equal to the dynamic cutoff threshold, a stop heating command is immediately generated and sent to the power control unit of the steam generator via the control signal line or communication bus, cutting off the power supply to the heating element. At this time, although the steam generator stops actively heating, the high-temperature water stored in the chamber is still in or near a boiling state. Its sensible and latent heat will continue to be transferred to the room through steam release, driving the indoor temperature to continue to rise.

[0052] S104. After cutting off the heating power input, obtain the current indoor ambient heat dissipation rate.

[0053] Among them, the ambient heat dissipation rate is used to represent the speed at which indoor ambient heat is lost to the outside under the current indoor and outdoor temperature difference and building insulation conditions. It is usually measured by the rate of temperature drop per unit time (°C / min) or the corresponding power value (W).

[0054] This step is executed after the heating power input is cut off, providing heat loss data for subsequent constant temperature control. Specifically, when the steam generator stops heating and the indoor temperature reaches its peak due to thermal hysteresis and begins to naturally decline, the control system monitors heat dissipation. The control system records the indoor temperature value at the moment heating is cut off as the initial value, and continuously collects indoor temperature data within a preset time window (e.g., 10 minutes). By calculating the temperature drop rate (°C / min) and combining it with parameters such as indoor air mass and specific heat capacity, the control system converts this temperature drop rate into the environmental heat dissipation rate. Alternatively, the control system can also directly calculate it using the indoor-outdoor temperature difference combined with the building's thermal resistance coefficient, with the formula: Environmental heat dissipation rate = (Indoor temperature - Outdoor temperature) / Total thermal resistance.

[0055] S105. Based on the minimum boiling power required for the steam generator to produce continuous and effective steam, calculate the heating duty cycle within a unit control cycle according to the ambient heat dissipation rate.

[0056] Among them, minimum boiling power refers to the minimum heating power required for the steam generator to maintain continuous boiling of water and stably output effective steam. If it is lower than this power, it may result in no steam generation or substandard steam quality. Unit control cycle indicates the length of time the system executes a complete "heating-pause" cycle during the constant temperature maintenance phase, for example, set to 300 seconds. Heating duty cycle is used to indicate the percentage of time heating is turned on in the total cycle within a unit control cycle.

[0057] This step is performed after the ambient heat dissipation rate is calculated, and its purpose is to formulate a control strategy for intermittent heating. Specifically, the control system compares the measured ambient heat dissipation rate with the minimum boiling power of the steam generator. Since the ambient heat dissipation rate represents the heat loss that needs to be compensated, and the minimum boiling power is the fixed output reference when the steam heater is turned on, the control system calculates the ratio of the two (ambient heat dissipation rate / minimum boiling power) and sets this ratio as the heating duty cycle. If the calculated ambient heat dissipation rate is greater than or equal to the minimum boiling power, it indicates that the isothermal maintenance phase has ended, and the control system can switch back to the full-power heating and temperature rise mode; if the ratio is less than 1, then this ratio is set as the heating duty cycle.

[0058] S106. Based on the heating duty cycle, control the steam generator to periodically switch between starting the minimum boiling power and stopping heating.

[0059] Periodic switching refers to a control mode that alternately executes the heating start and stop operations within a unit control cycle according to the calculated heating duty cycle.

[0060] This step, after determining the heating duty cycle, is continuously executed in a loop to achieve intelligent control during the constant temperature maintenance phase. Specifically, the control system, based on the calculated heating duty cycle and the preset unit control cycle, decomposes one control cycle into heating duration and stop duration. Heating duration = unit control cycle × heating duty cycle, and stop duration = unit control cycle × (1 - heating duty cycle). The timer inside the control system starts counting, first sending a command to control the steam generator to operate at minimum boiling power to maintain the heating duration; after the time is reached, a stop heating command is immediately sent, entering the stop duration phase. When the unit control cycle ends, the control system reacquires the ambient heat dissipation rate and updates the duty cycle, starting the switching control for the next cycle.

[0061] In this embodiment, by employing a dynamic cutoff threshold based on the thermal hysteresis effect calculated from the water state within the cavity, and a control strategy that calculates the heating duty cycle based on the minimum boiling power and the ambient heat dissipation rate, the residual phase change heat release can be used to drive the room temperature to approach the target inertia without overshoot. During the isothermal phase, precise matching of heat supply and demand is achieved through periodic switching. This effectively solves the problems of temperature overshoot caused by the thermal inertia of steam phase change in related technologies, as well as the inability to generate continuous and effective steam under low load due to insufficient power. Thus, the intelligent operation of the steam generator control system is achieved, taking into account both temperature control and stable steam output.

[0062] The above embodiments demonstrate the core logic of overshoot-free heating using thermal hysteresis and pulsed temperature control based on load matching. In practical applications, indoor thermal environments are often more complex. For example, the presence of people can alter heat demand, airflow can affect heat transfer efficiency, and the physical hysteresis of steam generation cannot be ignored. Therefore, it is necessary to combine specific biological distribution characteristics, temperature change slope, and equipment response characteristics to perform more in-depth and refined calibration of the control strategy.

[0063] Based on the above embodiments, the method provided in this embodiment will be described in further detail below. Please refer to... Figure 2 This is another flowchart illustrating an intelligent operation control method for steam air conditioning based on environmental perception, as described in this application.

[0064] S201. Real-time acquisition of the target temperature value of the indoor environment, the indoor temperature value, and the water temperature value and water capacity inside the steam generator cavity;

[0065] This step is similar to the description of step S101 in the above embodiment, and will not be repeated here.

[0066] S202. Based on the water temperature and water volume inside the cavity, calculate the remaining phase change heat released in the steam generator if the heating power is cut off at the current moment.

[0067] Among them, the residual phase change heat release refers to the total heat energy that can be released by the energy stored in the heating chamber during the subsequent inertial boiling and cooling process at the moment the power to the steam generator is cut off, including the sensible heat released by the cooling of the high-temperature water body and the latent heat of vaporization generated by the continued flash evaporation due to pressure changes.

[0068] Specifically, the steam generator control system executes this step immediately after acquiring the real-time water temperature and volume within the chamber. The control system invokes a preset thermodynamic calculation model. First, based on the specific heat capacity formula for water, it calculates the sensible heat energy released when the water in the chamber cools from its current high temperature to the non-boiling critical temperature (such as 98℃ or the reference temperature at which boiling ceases). Simultaneously, the control system, considering the saturated vapor pressure parameters under the current pressure, estimates the mass of water that undergoes secondary flash evaporation due to the disruption of thermal equilibrium at the moment of power failure, and calculates the latent heat energy released when this portion of water is converted into steam based on the latent heat constant of water. The control system adds the sensible heat energy and the latent heat energy to obtain the remaining phase change heat release at the current moment.

[0069] S203. Based on the indoor temperature value and the preset space heat conversion coefficient, calculate the temperature rise caused by the release of the remaining phase change energy into the indoor environment, and obtain the predicted temperature rise value.

[0070] The preset space heat conversion coefficient is used to represent the proportion of temperature increase that can be converted by a unit of heat input in an indoor space with a specific volume and insulation performance. This coefficient is preset by the control system at the factory or obtained by self-learning calibration through historical operating data; the predicted temperature rise value refers to the estimated value that the indoor temperature will continue to rise after the power is cut off.

[0071] Specifically, the steam generator control system executes this step after quantifying thermal inertia. The control system multiplies the remaining phase change heat released calculated in S202 by the space heat conversion coefficient to calculate the physical temperature rise caused by mechanical inertia.

[0072] Optionally, in some embodiments, the control system can also acquire current indoor biological distribution characteristic parameters, which include at least the number of people and the distance weight between each person and the steam air conditioner outlet; based on a preset biological thermo-metabolism model and distance weights, the indoor biological distribution characteristic parameters are mapped to the biological thermo-gain value of the current environment; a thermal compensation correction amount for the target temperature value is calculated based on the biological thermo-gain value; the thermal compensation correction amount is subtracted from the target temperature value to obtain the corrected target temperature value, and the corrected target temperature value is used as the reference value in the step of calculating the dynamic cutoff threshold.

[0073] Specifically, the control system simultaneously processes data from infrared or radar sensors to identify the number of people and the distance between each person and the air outlet. It then calculates the total biothermal gain value based on a preset model (e.g., higher weight for closer distances) and converts it into a corresponding temperature compensation value. If people are present, the control system will subtract and correct the original target temperature value (i.e., lower the target value); if there is no personnel data, the original target value is used directly.

[0074] S204. Subtract the predicted temperature rise from the target temperature value to calculate the dynamic cutoff threshold.

[0075] S205. When the indoor temperature reaches the dynamic cutoff threshold, a stop heating command is generated to cut off the heating power input of the steam generator, so that the remaining phase change heat released in the steam generator drives the indoor temperature to inertially approach the target temperature.

[0076] This step is similar to step S103 in the above embodiment, and will not be repeated here.

[0077] S206. After the heating power input is cut off, continuously monitor the rate of decrease of the indoor temperature value over time;

[0078] The descent slope refers to the rate of change of indoor temperature over time (dT / dt), which characterizes the natural cooling rate of the indoor environment after the loss of an active heat source.

[0079] Specifically, the steam generator control system initiates this step after executing a stop heating command and detecting that the indoor temperature has peaked and begun to decline. The control system records the change trajectory of the indoor temperature value at a preset sampling frequency (e.g., once every 10 seconds) and selects a stable cooling range (e.g., the process of the temperature decreasing from its peak by 0.2℃). The control system processes the temperature-time data points within this range using the least squares method or difference calculation method to calculate the linear decrease slope (negative value) of the indoor temperature over time at the current moment.

[0080] S207. Calculate the amount of heat supply required per unit time to maintain the current indoor temperature based on the descent slope, and obtain the environmental heat dissipation rate.

[0081] Among them, the heat supply per unit time refers to the number of joules of heat that must be injected into the room per unit time in order to offset the natural cooling trend.

[0082] Specifically, the steam generator control system uses the temperature drop slope obtained from S206 for energy conversion. The control system calls upon internally stored air physical parameters (such as air specific heat capacity and air density at standard atmospheric pressure) and preset estimated room volume (or user-input area parameters) to construct a heat balance equation. The control system multiplies the absolute value of the temperature drop slope by the total heat capacity of the room air to calculate the amount of heat lost per minute in the room, i.e., the environmental heat dissipation rate.

[0083] S208. Determine the target circulating air volume for uniformly dissipating heat into the indoor space within a unit control cycle based on the environmental heat dissipation rate.

[0084] The target circulating air volume refers to the optimal air delivery speed or air volume value that the fan should output during the constant temperature maintenance phase.

[0085] Specifically, after determining the amount of heat required, the steam generator control system further determines the air volume to supply that heat. The control system uses heat transfer formulas... The modified formula uses the ambient heat dissipation rate as the target heat Q, combined with the expected temperature difference between the air outlet and return air outlet. The system calculates the required air mass flow rate (m) based on the comfort temperature difference (e.g., 15°C) and the specific heat capacity of air (C). Then, the control system combines the air density parameter to convert the mass flow rate into the volumetric flow rate, which is the heat balance air volume required to offset the rate of ambient heat dissipation, and serves as the target circulating air volume.

[0086] S209. Obtain the effective heat transfer coefficient of the steam generator when it operates at minimum boiling power and is used for heat exchange with the target circulating air volume.

[0087] The effective heat transfer coefficient is used to represent the efficiency ratio (between 0 and 1) of the steam heat energy converted from heating being actually carried away by the flowing air and effectively output to the environment under a specific air volume. This coefficient is affected by wind speed.

[0088] Specifically, the steam generator control system recognizes that the rated power of the heater does not equal the actual heat output to the room, especially since heat exchange efficiency changes at low airflow rates. Based on the target circulating airflow determined in S208, the control system queries a pre-stored airflow-thermal efficiency mapping table or characteristic curve. This mapping table records the heat exchange efficiency of the steam generator's core heat exchange components (such as heat exchange copper tubes or mixing chambers) at different airflow speeds. The control system then matches this to the effective heat transfer coefficient corresponding to the current airflow rate. For example, at low airflow rates, this coefficient might be 0.85, indicating that 15% of the heat may be lost in the pipes or not carried away in time.

[0089] S210. The minimum boiling power is weighted by the effective heat transfer coefficient to obtain the effective output power of the steam generator under the current operating conditions.

[0090] Among them, effective output power refers to the effective heating power that the steam generator can actually contribute to the indoor environment when it is turned on.

[0091] Specifically, the control system performs this step to obtain accurate supply capacity data. Since the steam generator must operate at its minimum boiling power (e.g., 800W) to produce steam, but due to the heat transfer efficiency described in S209, the actual heat entering the room will be reduced. The control system multiplies the minimum boiling power value by the effective heat transfer coefficient, and the result is the effective output power. For example, with a boiling power of 800W and an airflow efficiency of 0.85, the effective output power is 680W.

[0092] S211. Calculate the ratio of ambient heat dissipation rate to effective output power, and use the ratio as the heating duty cycle of the steam generator in a unit control cycle.

[0093] S212. Monitor the time difference between the start-up minimum boiling power of the steam generator and the actual generation of phase change steam flow to obtain the phase change response hysteresis time.

[0094] Among them, the phase change response hysteresis time refers to the time interval between the moment when the control system issues the command to start heating and the moment when the sensor detects the actual steam outflow or a step change in the outlet temperature.

[0095] Specifically, the steam generator control system performs actual measurements during each heating cycle or a specific calibration cycle. The control system records the times when the relays close. Subsequently, high-frequency monitoring is performed on the temperature / humidity sensors located at the steam outlet or duct mixing point. When a steep increase in temperature / humidity values ​​consistent with steam release characteristics is detected, the time is marked as [time value missing]. Control system calculation - The phase transition response hysteresis time was obtained.

[0096] S213. The phase change response hysteresis time is superimposed on the theoretical heating time calculated based on the heating duty cycle to obtain the corrected actual heating time.

[0097] The theoretical heating time refers to the ideal energizing time calculated solely based on the law of conservation of energy, assuming that heating will produce steam; the actual heating time refers to the physical energizing time during which the control relay of the control system actually closes.

[0098] Specifically, the steam generator control system corrects the control timing to compensate for the invalid heating period identified in S212. First, the control system multiplies the unit control cycle length (e.g., 60 seconds) by the heating duty cycle obtained in S211 to derive the theoretical heating time (e.g., 30 seconds). Then, the control system adds the measured phase change response hysteresis time (e.g., 5 seconds) to the theoretical heating time to obtain the actual heating time (35 seconds).

[0099] S214. Based on the heating duty cycle, control the steam generator to periodically switch between starting the minimum boiling power and stopping heating.

[0100] This step specifically includes:

[0101] The heating power input of the steam generator is turned on at the start of the unit control cycle.

[0102] Start a timer to monitor the heating duration, and cut off the heating power input when the heating duration reaches the actual heating time;

[0103] The heating remains stopped for the remainder of the unit control cycle until the start of the next unit control cycle.

[0104] Optionally, in some embodiments, during the phase change response hysteresis time, the fan of the steam air conditioner is controlled to execute a preset anti-cold air micro-circulation speed, wherein the anti-cold air micro-circulation speed is less than the speed corresponding to the target circulating air volume.

[0105] When the phase change response hysteresis time is detected to end and steam begins to be released, the control fan switches from the anti-cold air micro-circulation speed to the speed corresponding to the target circulation air volume.

[0106] Among them, the anti-cold air micro-circulation speed refers to an extremely low average speed state maintained by the fan when there is no steam output. It is designed to maintain the micro-movement of airflow inside the machine to prevent sensor misjudgment, and at the same time avoid blowing unheated cold air to users.

[0107] Specifically, the steam generator control system enters the execution phase. At the beginning of each control cycle, the control system closes the heating circuit and simultaneously controls the fan to maintain a micro-circulation speed to prevent cold air from entering. At this time, the steam heater is working but not producing steam, and the fan runs at low speed to avoid cold air blowing in. When the control system timer reaches the phase change response hysteresis duration (or a steam output signal is detected in real time), it determines that effective heating has begun and immediately increases the fan speed to the target circulation air volume determined in S208, efficiently delivering steam into the room. When the timer reaches the actual heating duration calculated in S213, the control system disconnects the heating circuit and immediately adjusts the fan speed back to micro-circulation state or maintains it for a short period of purging before lowering it, until the cycle ends.

[0108] In this embodiment, by introducing a biological thermal gain value to correct the target temperature, accurately quantifying the environmental heat dissipation rate based on the indoor temperature drop slope, and combining the effective heat transfer coefficient and phase change response hysteresis time to perform multi-dimensional calibration of the actual heating time under the heating duty cycle, the control system can fully perceive the dynamic heat load composed of personnel and environment, and eliminate energy output errors caused by differences in airflow heat exchange efficiency and equipment physical response delays. This solves the problem of decreased temperature control accuracy and energy efficiency loss caused by fixed parameter models or timing misalignments under complex working conditions, thereby achieving end-to-end adaptive constant temperature control.
