Description

Technical Field

[0001] This application relates to the field of energy-saving air conditioning technology, and more specifically, to a multi-room thermal insulation control method, a fresh air control system, a multi-room thermal insulation control device, and an air conditioner. Background Technology

[0002] In multi-room residential and commercial environments, ducted air conditioning systems are the mainstream air conditioning equipment, effectively regulating indoor temperature while improving space utilization. However, they lack room insulation, especially multi-room collaborative insulation mechanisms, leading to a lag in cooling and heating load response. After users leave for a short time, the indoor thermal environment rapidly degrades to outdoor levels, requiring compressors and fans to operate at high power continuously to restore temperature, significantly increasing energy consumption. Furthermore, existing equipment often focuses on single temperature control or independent fresh air functions, failing to deeply integrate multi-room insulation strategies with the fresh air system. This results in either excessive indoor CO2 concentrations or indoor temperatures dropping to outdoor levels upon return, impacting user health and comfort.

[0003] In summary, existing ducted air conditioning system control schemes lack multi-room collaborative insulation mechanisms, which affects user comfort. Summary of the Invention

[0004] The main purpose of this application is to provide a multi-room thermal insulation control method, a fresh air control system, a multi-room thermal insulation control device, and an air conditioner, so as to at least solve the problem that the existing duct air conditioning system control scheme lacks a multi-room collaborative thermal insulation mechanism in unattended scenarios, which affects user comfort.

[0005] To achieve the above objectives, according to one aspect of this application, a multi-room thermal insulation control method is provided, comprising: acquiring current temperature data of each insulated room, wherein the insulated room is a room in which personnel have been detected leaving and a thermal insulation command has been received from a wired controller; calculating the temperature difference between the current temperature data of each insulated room and a target temperature value; identifying rooms requiring thermal insulation and the proportion of such rooms in the insulated room based on the temperature difference value; wherein the rooms requiring thermal insulation are high-heat-load rooms where the temperature difference value is greater than a set value; adjusting the operating level of a ducted air conditioner according to the proportion and the number of insulated rooms; and adjusting the opening degree of the air valves in each insulated room according to the temperature difference value of each insulated room; wherein the air valves include an indoor air outlet valve, an indoor air return valve, an outdoor air outlet valve, and an outdoor air return valve.

[0006] Optionally, after adjusting the opening degree of the air valve of each of the insulated rooms according to the temperature difference value of each of the insulated rooms, the method further includes: collecting the carbon dioxide concentration of the insulated rooms; and adjusting the opening degree of the air valve of the insulated rooms according to the carbon dioxide concentration of the insulated rooms.

[0007] Optionally, adjusting the opening degree of the air valve in each of the insulated rooms according to the carbon dioxide concentration in each of the insulated rooms includes: when the carbon dioxide concentration is less than or equal to a set concentration, controlling the indoor return air valve and the indoor outlet air valve of the insulated room to be fully open, and the outdoor outlet air valve and the outdoor return air valve to be fully closed; when the carbon dioxide concentration is greater than the set concentration, controlling the opening degree of the indoor return air valve of the insulated room to be adjusted to a first opening degree, the opening degree of the outdoor return air valve to be adjusted to a second opening degree, and the indoor outlet air valve to be fully open, wherein the first opening degree is greater than the second opening degree.

[0008] Optionally, adjusting the opening degree of the air valve in each of the insulated rooms according to the temperature difference value of each of the insulated rooms includes: constructing a mapping table of air duct machine settings, the temperature difference value, and the air valve opening degree; and adjusting the air valve opening degree of each of the insulated rooms according to the mapping table, the operating settings, and the temperature difference value.

[0009] Optionally, adjusting the operating level of the ducted air conditioner according to the ratio and the number of insulated rooms includes: adjusting the operating level of the ducted air conditioner to the highest level when the number of insulated rooms is greater than a first set number and the ratio is greater than or equal to a set ratio; adjusting the operating level of the ducted air conditioner to the second highest level when the number of insulated rooms is greater than the first set number and the ratio is less than the set ratio; and adjusting the operating level of the ducted air conditioner to the medium level when the number of insulated rooms is less than a second set number and the ratio is greater than or equal to the set ratio. If the number of insulated rooms is greater than the second set number; if the number of insulated rooms is less than the second set number and the ratio is less than the set ratio, adjust the operating speed of the duct air conditioner to low; if the number of insulated rooms is between the first set number and the second set number and the ratio is greater than or equal to the set ratio, adjust the operating speed of the duct air conditioner to the second-highest speed; if the number of insulated rooms is between the first set number and the second set number and the ratio is less than the set ratio, adjust the operating speed of the duct air conditioner to medium speed.

[0010] Optionally, after adjusting the opening degree of the air valve of each of the insulated rooms according to the temperature difference value of each of the insulated rooms, the method further includes: detecting the continuous unoccupied time of each of the insulated rooms, and closing the air valve of each of the insulated rooms where the continuous unoccupied time is longer than a set time.

[0011] Optionally, before acquiring the current temperature data of the multiple insulated rooms, the method further includes: identifying the insulated rooms using personnel detection sensors for each room, wherein the personnel detection sensors include at least one of millimeter-wave radar and thermal infrared sensors.

[0012] According to another aspect of this application, a fresh air control system is provided, comprising: a controller for executing any of the multi-room thermal insulation control methods described above; a ducted air conditioner including an evaporator and a fan for realizing the cooling or heating circulation and air delivery of the fresh air control system according to the control commands output by the controller; a damper having a motor drive mechanism and a position sensor inside, for adjusting the valve opening according to the control commands output by the controller, the damper including an indoor air outlet damper, an indoor air return damper, an outdoor air outlet damper, and an outdoor air return damper; a temperature sensor and a carbon dioxide sensor, the temperature sensor and the carbon dioxide sensor being installed in the room and communicatively connected to the controller for detecting the temperature data and carbon dioxide concentration of each room.

[0013] According to another aspect of this application, a multi-room thermal insulation control device is provided, comprising: an acquisition unit, configured to acquire current temperature data of each insulated room, wherein the insulated room is a room after personnel have been detected leaving; a calculation unit, configured to calculate the temperature difference between the current temperature data of each insulated room and a target temperature value, identify rooms requiring thermal insulation among the insulated rooms based on the temperature difference value, and identify the proportion of rooms requiring thermal insulation among the insulated rooms, wherein the rooms requiring thermal insulation are high-heat-load rooms where the temperature difference value is greater than a set value; and a first adjustment unit, configured to adjust the operating level of the ducted air conditioner according to the proportion and the number of insulated rooms, and adjust the opening degree of the air valves of each insulated room according to the temperature difference value of each insulated room; wherein the air valves include indoor air outlet valves, indoor air return valves, outdoor air outlet valves, and outdoor air return valves.

[0014] According to another aspect of this application, an electronic device is provided, comprising: one or more processors, a memory, and one or more programs, wherein the one or more programs are stored in the memory and configured to be executed by the one or more processors, the one or more programs including methods for performing any of the multi-room thermal control methods described above.

[0015] By applying the technical solution of this application, dynamic and graded response of insulation strategies in multi-room unoccupied scenarios is achieved by adjusting the fan speed and damper opening based on temperature difference, proportion, and number of rooms. Traditional solutions control start-stop based only on a single temperature difference or total number of people, resulting in some rooms being too cold or too hot, and wasting energy. This solution accurately judges the overall heat load demand of the system by identifying the "percentage of rooms with high heat load insulation" and classifies the fan speed according to the number of rooms (e.g., different fan speeds correspond to extra-large / medium / small insulation needs), avoiding the two extreme modes of "full power on" or "full off with no insulation". At the same time, the damper opening is independently adjusted based on the actual temperature difference of each room, so that each room can achieve long-term insulation measures even when unoccupied, allowing users to experience a comfortable temperature when they return to the room after a short absence. This solves the problem that existing ducted air conditioning system control solutions lack a multi-room collaborative insulation mechanism in unoccupied scenarios, which affects user comfort.

[0027] As described in the background section, existing ducted air conditioning system control schemes lack a multi-room collaborative insulation mechanism, which affects user comfort.

[0031] This embodiment provides a multi-room thermal insulation control method that runs on a mobile terminal, computer terminal, or similar computing device. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Also, although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in a different order than that shown here.

[0032] Figure 2 This is a flowchart of a multi-room thermal insulation control method according to an embodiment of this application. Figure 2 As shown, the method includes the following steps:

[0033] Step S201: Obtain the current temperature data of each insulated room, wherein the insulated room is the room where personnel are detected leaving and the insulated command is received from the wired controller;

[0034] Step S202: Calculate the temperature difference between the current temperature data and the target temperature value of each of the above-mentioned insulated rooms, identify the rooms that need to be insulated among the above-mentioned insulated rooms based on the temperature difference value, and identify the proportion of the rooms that need to be insulated among the above-mentioned insulated rooms, wherein the rooms that need to be insulated are high heat load rooms whose temperature difference value is greater than the set value.

[0035] The target temperature value can be set according to the most comfortable temperature for the human body.

[0036] Step S203: Adjust the operating level of the duct air conditioner according to the above ratio and the number of the above-mentioned insulated rooms, and adjust the opening degree of the air valve of each of the above-mentioned insulated rooms according to the above-mentioned temperature difference value of each of the above-mentioned insulated rooms; wherein, the air valve includes indoor air outlet valve, indoor air return valve, outdoor air outlet valve and outdoor air return valve.

[0037] This embodiment, by applying steps S201, S202, and S203, adjusts the fan speed and damper opening based on temperature difference, proportion, and number of rooms, achieving dynamic, tiered response of insulation strategies in multi-room unoccupied scenarios. Traditional solutions control start / stop based solely on a single temperature difference or total number of people, leading to some rooms being too cold or too hot, and wasting energy. This solution identifies the "percentage of rooms with high heat load" to accurately determine the overall system heat load demand, and tiers the fan speed based on the number of rooms (e.g., different fan speeds correspond to extra-large / medium / small insulation needs), avoiding the extreme modes of "full power on" or "full off with no insulation." Simultaneously, the damper opening is independently adjusted based on the actual temperature difference of each room, ensuring long-term insulation even when no one is present, allowing users returning from short periods of absence to experience a comfortable temperature. This solves the problem of existing ducted air conditioning system control schemes lacking a multi-room collaborative insulation mechanism in unoccupied scenarios, which negatively impacts user comfort.

[0038] In the specific implementation process, after adjusting the opening degree of the air valve of each of the above-mentioned insulated rooms according to the temperature difference value of each of the above-mentioned insulated rooms, the above-mentioned method further includes: collecting the carbon dioxide concentration of the above-mentioned insulated rooms; and adjusting the opening degree of the air valve of the above-mentioned insulated rooms according to the carbon dioxide concentration of the above-mentioned insulated rooms.

[0039] In this embodiment, a closed-loop feedback mechanism for CO2 concentration is introduced based on thermal insulation control, deeply integrating the two independent control objectives of "thermal comfort" and "air health" for the first time. Traditional ducted air conditioners completely shut off fresh air or keep it on in unattended thermal insulation mode, leading to excessive CO2 accumulation or energy waste. This solution continuously monitors CO2 concentration during thermal insulation and dynamically fine-tunes the air valve combination to achieve an intelligent balance of "prioritizing thermal insulation and providing fresh air on demand." When CO2 is within the limit, internal circulation is maintained to avoid temperature fluctuations caused by the mixing of hot and cold air; when it exceeds the limit, only a small amount of fresh air is introduced, using indoor return air to preheat / precool the fresh air, significantly reducing the energy consumption for heating / cooling the fresh air. This mechanism enables the system to maintain a stable indoor temperature while keeping the indoor CO2 concentration below the set value (e.g., 800 ppm) for a long time, effectively preventing "closed space fatigue syndrome" and achieving a dual improvement in health and energy saving.

[0040] Specifically, adjusting the opening degree of the air valves in each of the aforementioned insulated rooms according to the carbon dioxide concentration in each of the aforementioned insulated rooms includes: when the carbon dioxide concentration is less than or equal to a set concentration, controlling the indoor return air valve and the indoor outlet air valve of the aforementioned insulated room to be fully open, and the outdoor outlet air valve and the outdoor return air valve to be fully closed; when the carbon dioxide concentration is greater than the set concentration, controlling the opening degree of the indoor return air valve of the aforementioned insulated room to be adjusted to a first opening degree, the opening degree of the outdoor return air valve to be adjusted to a second opening degree, and the indoor outlet air valve to be fully open, wherein the first opening degree is greater than the second opening degree.

[0041] The CO2 concentration can be set to 800 ppm.

[0042] In this embodiment, the control logic of the air valve linkage driven by CO2 concentration is further refined, and a dual-mode switching strategy of "internal circulation - micro-fresh air" is proposed, with precise setting of the opening ratio. For example, when CO2 ≤ 800ppm, the outdoor return air valve is completely closed, the indoor return air valve and the indoor outlet air valve are fully opened to construct a closed internal circulation channel and maximize the retention of heat energy; when CO2 > 800ppm, the indoor return air and outdoor return air valves are opened in a "9:1" ratio (i.e., 90% return air + 10% fresh air), the indoor outlet air valve is fully opened, and the outdoor outlet air valve is opened synchronously with the outdoor return air valve to maintain system pressure balance and avoid positive pressure that prevents fresh air from entering. This design not only ensures ventilation efficiency, but also avoids room temperature fluctuations caused by sudden changes in air volume through the principle of "constant total air volume".

[0043] More specifically, adjusting the opening degree of the air valve in each of the aforementioned insulated rooms according to the aforementioned temperature difference value includes: constructing a mapping table of air duct machine settings, the aforementioned temperature difference value, and the aforementioned air valve opening degree; and adjusting the opening degree of the aforementioned air valve in each of the aforementioned insulated rooms according to the aforementioned mapping table, the aforementioned operating settings, and the aforementioned temperature difference value.

[0044] In this embodiment, a mapping table of "air conditioner speed setting - temperature difference - damper opening" is established to achieve standardization, quantification, and trainability of control parameters. Traditional systems rely on experience-based PID control, resulting in large parameter drift and difficulty in adapting to different models. This solution integrates historical operating data with experimental conditions (such as temperature difference 0~4℃, speed settings low / medium / high / ultra-strong) into a discrete control matrix, embedded in the controller's local storage. This ensures that each adjustment has clear data support, eliminating the need for online calculations and improving response speed. Furthermore, the mapping table supports OTA upgrades and can be dynamically optimized according to user habits, adapting to different building envelopes and climate zones.

[0045] Further, adjusting the operating level of the ducted air conditioner according to the aforementioned ratio and the number of insulated rooms includes: when the number of insulated rooms is greater than a first preset number and the aforementioned ratio is greater than or equal to a preset ratio, adjusting the operating level of the ducted air conditioner to the highest level; when the number of insulated rooms is greater than the first preset number and the aforementioned ratio is less than the preset ratio, adjusting the operating level of the ducted air conditioner to the second highest level; when the number of insulated rooms is less than a second preset number and the aforementioned ratio is greater than or equal to the preset ratio, adjusting the operating level of the ducted air conditioner to the medium level, wherein the first preset number is less than a second preset number and the aforementioned ratio is greater than or equal to the preset ratio. If the number of insulated rooms is greater than the second set number; if the number of insulated rooms is less than the second set number and the ratio is less than the set ratio, adjust the operating speed of the duct air conditioner to low; if the number of insulated rooms is between the first set number and the second set number and the ratio is greater than or equal to the set ratio, adjust the operating speed of the duct air conditioner to the second-highest speed; if the number of insulated rooms is between the first set number and the second set number and the ratio is less than the set ratio, adjust the operating speed of the duct air conditioner to medium speed.

[0046] In this embodiment, a four-level control logic is constructed to adjust the operating speed of the ducted air conditioner based on the number and proportion of insulated rooms. This realizes a refined decision tree model for the industry's multi-room insulation needs. Traditional systems only make binary judgments based on "whether there are people" or adjust linearly based on the total temperature difference, failing to recognize the essential difference between "3 out of 5 rooms need insulation" and "all 3 rooms need insulation". This solution sets a first set quantity (e.g., 5 rooms) and a second set quantity (e.g., 3 rooms), combined with a proportion threshold (e.g., 50%), to divide six typical operating conditions, each corresponding to a unique fan speed (highest / second highest / medium / low), ensuring that the system can match the optimal operating point under different load combinations. For example, when "the number of insulated rooms > 5 and the proportion of high heat load rooms ≥ 50% of insulated rooms", it directly enters the high-power setting to avoid temperature lag; when "the number of insulated rooms is between 3 and 5 and the above proportion < 50%", it only uses the medium setting to avoid excessive energy consumption. This logic significantly improves control accuracy and energy efficiency, enabling the system to operate stably even in complex apartment layouts.

[0047] Furthermore, after adjusting the opening degree of the air valve of each of the aforementioned insulated rooms according to the temperature difference value of each of the aforementioned insulated rooms, the method further includes: detecting the continuous unoccupied time of each of the aforementioned insulated rooms, and closing the air valve of each of the aforementioned insulated rooms where the continuous unoccupied time is longer than a set time.

[0048] In this embodiment, "continuous unoccupied time" is introduced as the automatic sleep trigger condition for the system, solving the long-overlooked energy consumption problem of "overheating." This avoids the issue of continuous heating for several hours even when no one returns, resulting in huge energy waste. This solution uses a built-in timer to independently record the unoccupied time for each insulated room. When the time exceeds a user-defined threshold (e.g., 60 minutes), all air valves in that room are automatically shut off, completely stopping air supply and return, entering an "energy-saving silent" state. This mechanism avoids the irrational strategy of "continuously consuming power in case someone returns," and users can customize the heating duration for unoccupied rooms (e.g., 30 minutes / 60 minutes).

[0049] Specifically, before acquiring the current temperature data of the multiple insulated rooms, the method further includes: identifying the insulated rooms using personnel detection sensors for each room, wherein the personnel detection sensors include at least one of millimeter-wave radar and thermal infrared sensors.

[0050] In this embodiment, millimeter-wave radar or thermal infrared sensors are used for personnel detection, and room insulation is achieved by receiving a user's manual command to activate the insulation mode. This solution automatically identifies the presence of human activity (heartbeat, micro-movements, thermal radiation) in the room by deploying non-contact sensors. The insulation process is only initiated when it is confirmed that a person has left and a user-triggered insulation command is received, eliminating false alarms. Millimeter-wave radar can penetrate curtains and clothing without being affected by obstructions; thermal infrared sensors can distinguish between humans and pets, reducing the false alarm rate. This technology gives the system "human-like perception" capabilities, achieving truly unattended intelligent insulation, significantly improving user experience and system automation.

[0051] Figure 3 Here is a structural block diagram of the fresh air control system, such as Figure 3 As shown, the fresh air control system includes:

[0052] The controller is used to execute any of the above-described multi-room thermal insulation control methods.

[0053] The aforementioned ducted air handling unit includes an evaporator and a fan, and is used to realize the cooling or heating circulation and air delivery of the fresh air control system according to the control commands output by the aforementioned controller.

[0054] The air valve is equipped with a motor drive mechanism and a position sensor inside, which are used to adjust the valve opening according to the control command output by the controller. The air valve includes an indoor air outlet valve, an indoor air return valve, an outdoor air outlet valve, and an outdoor air return valve.

[0055] Temperature sensors and carbon dioxide sensors are installed in the room and are connected in communication with the controller to detect the temperature data and carbon dioxide concentration of each room.

[0056] This embodiment fully constructs a new air control system architecture of "control-execution-sensing," and for the first time, engineering and implementing a multi-room thermal insulation control method in unmanned scenarios into a mass-producible hardware system. Unlike existing ducted air conditioners that only have temperature control and unidirectional air supply, this system integrates four independent air valves (including outdoor air supply / outdoor return air), dual-parameter sensors (temperature + CO2 concentration), an intelligent controller, and a fan coordination module, forming a closed-loop feedback control chain. All components are connected through a standardized communication protocol, and the controller can independently run all the logic of the aforementioned multi-room thermal insulation control method.

[0057] The structural diagram of the specific fresh air control system for multi-room thermal insulation control is shown below. Figure 4 As shown in the diagram, the airflow circulation structure of the fresh air control system is as follows: Figure 5 As shown.

[0058] To enable those skilled in the art to better understand the technical solution of this application, the implementation process of the multi-room thermal insulation control method of this application will be described in detail below with reference to specific embodiments.

[0059] This embodiment relates to a specific multi-room thermal insulation control method, including a multi-room long-term thermal insulation and fresh air coordinated balance control method based on fan control and a fresh air control system. The system collects environmental parameters of multiple rooms in real time, constructs a "multi-room thermal insulation-fresh air-air valve" coupled model, and dynamically and collaboratively optimizes the indoor unit fan speed and the opening of each branch air valve. While ensuring the stability of the basic thermal environment of each room and maintaining long-term thermal insulation performance, it intelligently adjusts the proportion of fresh air introduction to achieve a balance between energy consumption reduction and health improvement, effectively solving the technical problems of high energy consumption, slow recovery and poor air quality of traditional systems.

[0060] Specific multi-room thermal insulation control methods, such as Figure 6 As shown, it includes the following steps:

[0061] S1: Number of rooms where the inspection personnel left and received the insulation command from the wired controller;

[0062] The air conditioner will only activate its heat preservation function for the room after it receives a command from the wired controller to detect whether there are people in the room.

[0063] S2: Monitor temperature and determine the proportion of units within the corresponding temperature range;

[0064] Temperature sensors monitor the ambient temperature in each insulated room in real time and transmit the data to the controller. The controller compares the current temperature with the preset temperature target value to determine the proportion of insulated rooms that are within the preset heat load range.

[0065] S3: The opening degree of the fan and the damper is adjusted in a coordinated manner;

[0066] Based on the number of insulated rooms and the proportion of rooms with high heat loads among the insulated rooms, the controller adjusts the fan speed and sends control commands to the intelligent air valve device, driving the air valve motor to adjust the air valve to the corresponding opening position.

[0067] S4: CO2 concentration monitoring and fine-tuning of air valve linkage;

[0068] After the air valve opening is adjusted, the controller detects changes in the carbon dioxide concentration in the room and fine-tunes the air valve opening to ensure that the air volume distribution of the insulated rooms meets the heat load requirements, thereby reducing energy consumption while insulating multiple rooms and improving indoor air quality.

[0069] S5: Dynamic optimization and energy management;

[0070] During system operation, the controller monitors changes in room temperature, carbon dioxide concentration, and damper opening every 5 minutes, dynamically optimizing the control strategy based on real-time data. When the heat load range of the insulated room changes, the opening of each damper is adjusted promptly to meet the new insulation requirements; simultaneously, the carbon dioxide concentration is kept within the normal range by reasonably controlling the adjustment range of each damper; if no one returns after a certain period of time, the air conditioner automatically shuts off to reduce energy consumption. The insulation time can be manually input by the user, such as 30 minutes.

[0071] The following is a detailed description of this solution using specific examples:

[0072] E1: The unit is started and running.

[0073] E2: Upon receiving a heat preservation command from the wired controller, if no one is detected in the room for more than 2 minutes, it is identified as a person leaving, the wired controller executes the heat preservation strategy, and detects the number of rooms to be insulated.

[0074] The air conditioner will only activate its heat preservation function for the room after it receives a command from the wired controller to detect whether there are people in the room.

[0075] 1. If the number of insulated rooms is greater than 5, the temperature sensor will further detect the indoor ambient temperature;

[0076] This indicates that there are a large number of rooms requiring insulation, and the demand for insulation is high.

[0077] 1.1 If the insulated room meets |T 环 -T 设 | The proportion of units with ≥2 in the total number of insulated rooms is ≥50%. The fans are adjusted to work at the highest setting, and the indoor air supply and return valves are fully open. At this time, the room insulation demand is high.

[0078] This indicates that a large number of indoor air dampers have been activated, and the condition |T| is met. 环 -T 设 The high proportion of units with a temperature ≥2℃ indicates a large demand for total room insulation. The ducted air conditioner must operate at its highest speed to increase the airflow rate and prevent airflow temperature stratification (cold air sinks and hot air rises).

[0079] 1.2 If the insulated room meets |T 环 -T 设 If the proportion of units with a capacity of ≥2 to the total number of insulated rooms is less than 50%, adjust the fan to work at the enhanced setting, and fully open the indoor air supply and return dampers. Since there are a large number of rooms that need to be insulated at this time, the room insulation priority is still higher than carbon dioxide. Then, the CO2 concentration sensor detects the CO2 concentration.

[0080] This indicates that a large number of indoor air dampers have been activated, but the condition |T| is met. 环 -T 设 The low proportion of units with a temperature ≥2℃ indicates a large overall room insulation requirement. To ensure energy efficiency, ducted air conditioners do not need to be turned on at their highest speed; they only need to be run at a higher speed to prevent airflow temperature stratification (cold air sinks, hot air rises).

[0081] A: If the carbon dioxide concentration is ≤800ppm, maintain the existing air valve opening, fully open the indoor return air valve, and fully close the outdoor return air valve to perform internal circulation; and every 5 minutes, the CO2 concentration sensor and temperature sensor will remeasure the indoor ambient temperature and carbon dioxide concentration.

[0082] This indicates that the room has a high need for insulation, and the CO2 concentration is within the normal threshold range. Therefore, it is not necessary to open the outdoor return air valve and allow the airflow to circulate completely internally to prevent airflow temperature stratification (cold air sinks and hot air rises).

[0083] B: If the carbon dioxide concentration is >800ppm, the total air volume will remain unchanged. The indoor return air valve of the room with excessive CO2 concentration will be opened to 90% and the outdoor return air valve will be opened to 10% to circulate the air.

[0084] This indicates that the indoor carbon dioxide concentration exceeds the normal range. If people return to this room, it will affect their health. Therefore, the outdoor return air valve should be opened, and the outdoor outlet air valve should be opened accordingly, with the opening degree being the same as that of the outdoor return air valve (if the outdoor outlet air valve is not opened, the total air pressure in the room will gradually increase, affecting the return of outdoor fresh air). However, at this time, the room has a greater need for heat preservation. Therefore, only the outdoor return air valve is opened to 10% for internal and external circulation. At the same time, the fresh air duct is integrated into the indoor return air duct to preheat or precool the outdoor fresh air using the temperature of the indoor air, preventing large fluctuations in the room temperature caused by the introduction of outdoor fresh air.

[0085] The valve opening degree is obtained by dividing the return air / outlet air area by the return air / outlet air area when the indoor return air / outlet air valve is fully open. The parameters corresponding to different valve opening degrees are fixed and input into the controller in advance; the valve can be closed when the CO2 concentration drops to 800ppm.

[0086] 2. If 3 ≤ number of rooms requiring insulation ≤ 5, the temperature sensor will further detect the indoor ambient temperature;

[0087] This indicates that the number of rooms requiring insulation is moderate, and the insulation demand is moderate.

[0088] 2.1 If |T 环 -T 设|The proportion of units with ≥2 is ≥50%, the fan is adjusted to work in the enhanced mode, and the indoor air supply and return air valves are fully open.

[0089] This indicates that the room has a moderate amount of insulation, but meets the requirements of |T 环 -T 设 The proportion of units with a temperature of ≥2℃ is high, and the room insulation demand is large. Therefore, the fan is adjusted to work at the enhanced setting, and the indoor air supply and return dampers are fully open.

[0090] A: If the carbon dioxide concentration is ≤800ppm, maintain the existing air valve opening, fully open the indoor return air valve, and fully close the outdoor return air valve to perform internal circulation; and every 5 minutes, the CO2 concentration sensor and temperature sensor will remeasure the indoor ambient temperature and carbon dioxide concentration.

[0091] B: If the carbon dioxide concentration is >800ppm, the total air volume will remain unchanged. The indoor return air valve of the room with excessive CO2 concentration will be opened to 90% and the outdoor return air valve will be opened to 10% to circulate the air.

[0092] This indicates that the CO2 concentration exceeds the normal threshold range. Therefore, the outdoor return air valve should be opened, and the outdoor outlet air valve should be opened accordingly, with the opening degree matching that of the outdoor return air valve. However, the number of rooms requiring insulation is still within a moderate range, and the requirement of |T| must be met. 环 -T 设 The proportion of units with a temperature of ≥2℃ is high, and the demand for room insulation is still relatively large. Therefore, the outdoor return air valve is only opened to 10% of its opening.

[0093] 2.2 If |T 环 -T 设 |If the proportion of units with ≥2 is <50%, adjust the fan to operate at normal speed, and fully open the indoor air supply and return dampers;

[0094] This indicates that the room has a moderate level of insulation and simultaneously meets the requirement of |T 环 -T 设 The proportion of units with a temperature ≥2℃ is small, and the room insulation requirement is moderate. Therefore, the fan should be adjusted to operate at normal speed, and the indoor air supply and return dampers should be fully open.

[0095] A: If the carbon dioxide concentration is ≤800ppm, maintain the existing air valve opening, fully open the indoor return air valve, and open the outdoor return air valve to perform internal circulation; and every 5 minutes, the CO2 concentration sensor and temperature sensor will remeasure the indoor ambient temperature and carbon dioxide concentration.

[0096] B: If the carbon dioxide concentration is >800ppm, the total air volume will remain unchanged. The indoor return air valve of the room with excessive CO2 concentration will be opened to 80% and the outdoor return air valve will be opened to 20% to circulate the air.

[0097] This indicates that the CO2 concentration exceeds the normal threshold range. Therefore, the outdoor return air valve should be opened, and the outdoor outlet air valve should be opened accordingly, with the opening degree matching that of the outdoor return air valve. At this point, the number of rooms requiring insulation is still within a moderate range, but meets the requirement of |T 环 -T 设 The proportion of units with a temperature ≥2℃ is low, the room insulation requirement is small, and the CO2 concentration has a significant impact. Therefore, the outdoor return air valve is opened to 20%.

[0098] 3. If the number of rooms requiring insulation is less than 3, the temperature sensor will further detect the indoor ambient temperature;

[0099] This indicates that the number of rooms requiring insulation is small.

[0100] 3.1 If |T 环 -T 设 |The proportion of units with ≥2 is ≥50%, the fans are adjusted to operate at normal speed, and the indoor air supply and return air valves are fully open.

[0101] This indicates that the room has insufficient insulation, but it still meets the requirement of |T 环 -T 设 The proportion of units with a temperature of ≥2℃ is high, and the total room insulation requirement is relatively small. Therefore, the fans should be adjusted to operate at normal speed, and the indoor air supply and return dampers should be fully open.

[0102] 3.2. If |T 环 -T 设 If the proportion of units with a capacity of ≥2 is less than 50%, adjust the fan to operate at a low speed and fully open the indoor air supply and return dampers.

[0103] This indicates that the room insulation is insufficient and meets the requirement of |T 环 -T 设 The proportion of units with a temperature of ≥2℃ is low, and the room insulation requirement is small. Therefore, the fan is adjusted to operate at a low speed, and the indoor air supply and return dampers are fully open.

[0104] A: If the carbon dioxide concentration is ≤800ppm, maintain the existing air valve opening, fully open the indoor air supply and return air valves, and fully close the outdoor air supply and return air valves to perform internal circulation; and every 5 minutes, the CO2 concentration sensor and temperature sensor will remeasure the indoor ambient temperature and carbon dioxide concentration.

[0105] B: If the carbon dioxide concentration is >800ppm, the total air volume will remain unchanged. The indoor return air valve of the room with excessive CO2 concentration will be opened to 80% and the outdoor return air valve will be opened to 20% to circulate the air.

[0106] This indicates that the CO2 concentration exceeds the normal threshold range. The outdoor return air valve should be opened, and the outdoor outlet air valve should open accordingly, with the opening degree matching that of the outdoor return air valve. At this point, the number of rooms requiring insulation is small, and the requirement of |T| is met. 环 -T 设 The proportion of units with a temperature ≥2℃ is low, the room insulation requirement is small, and the CO2 concentration has a significant impact. Therefore, the outdoor return air valve is opened to 20%.

[0107] 4. If no one returns after a certain period of time, the air conditioner will automatically turn off to reduce energy consumption. The user can decide the heat preservation time, such as 60 minutes.

[0108] This application also provides a multi-room thermal insulation control device. It should be noted that the multi-room thermal insulation control device of this application can be used to execute the multi-room thermal insulation control method provided in this application. This device is used to implement the above embodiments and preferred embodiments; details already described will not be repeated. As used below, the term "module" can refer to a combination of software and / or hardware that performs a predetermined function. Although the device described in the following embodiments is preferably implemented in software, hardware implementation, or a combination of software and hardware, is also possible and contemplated.

[0109] The following describes the multi-room thermal insulation control device provided in the embodiments of this application.

[0110] Figure 7 This is a schematic diagram of a multi-room thermal insulation control device according to an embodiment of this application. Figure 7 As shown, the device includes:

[0111] The acquisition unit 71 is used to acquire the current temperature data of each insulated room, wherein the insulated room is the room that has been detected to have personnel leaving and has received an insulated command from the wired controller.

[0112] The calculation unit 72 is used to calculate the temperature difference between the current temperature data and the target temperature value of each of the above-mentioned insulated rooms, and to identify the proportion of high heat load rooms among the multiple insulated rooms based on the temperature difference value.

[0113] The first adjustment unit 73 is used to adjust the operating level of the air duct machine according to the above ratio and the number of the above-mentioned insulated rooms, and to adjust the opening degree of the air valve of each of the above-mentioned insulated rooms according to the above-mentioned temperature difference value of each of the above-mentioned insulated rooms; wherein, the air valve includes an indoor air outlet valve, an indoor air return valve, an outdoor air outlet valve and an outdoor air return valve.

[0114] In this embodiment, the acquisition unit is used to acquire the current temperature data of multiple insulated rooms, wherein the insulated rooms are those where personnel have been detected leaving; the calculation unit is used to calculate the temperature difference between the current temperature data of each insulated room and the target temperature value, and to identify the rooms requiring insulation and the proportion of the rooms requiring insulation based on the temperature difference value, wherein the rooms requiring insulation are high heat load rooms where the temperature difference value is greater than a set value; the first adjustment unit is used to adjust the operating level of the duct fan according to the proportion and the number of insulated rooms, and to adjust the opening degree of the air valves in each insulated room according to the temperature difference value of each insulated room; wherein the air valves include indoor air outlet valves, indoor air return valves, outdoor air outlet valves, and outdoor air return valves. By adjusting the fan level and air valve opening according to the temperature difference value, proportion, and number of rooms, a dynamic hierarchical response of the insulation strategy in a multi-room unoccupied scenario is achieved. Traditional solutions control the start and stop based only on a single temperature difference or the total number of people, resulting in some rooms being too cold or too hot and wasting energy. This solution accurately determines the overall heat load demand of the system by identifying the percentage of rooms requiring insulation. It then categorizes the insulation levels based on the number of rooms (e.g., different fan speeds correspond to extra-large / medium / small insulation needs), avoiding the extreme scenarios of "full power" or "full off with no insulation." Simultaneously, it independently adjusts the opening of air dampers based on the actual temperature difference in each room, ensuring long-term insulation even when no one is in the room. This allows users to return to a comfortable temperature after a short absence. This solution addresses the problem of existing ducted air conditioning systems lacking a multi-room collaborative insulation mechanism for unoccupied scenarios, which negatively impacts user comfort.

[0116] In one optional embodiment, the second regulating unit includes a first control module and a second control module; the first control module is used to control the indoor return air valve and the indoor air outlet valve of the insulated room to be fully open and the outdoor air outlet valve and the outdoor return air valve to be fully closed when the carbon dioxide concentration is less than or equal to a set concentration; the second control module is used to control the opening degree of the indoor return air valve of the insulated room to be adjusted to a first opening degree, the opening degree of the outdoor return air valve to be adjusted to a second opening degree, the indoor air outlet valve to be fully open, and the outdoor air outlet valve to be adjusted to a second opening degree when the carbon dioxide concentration is greater than the set concentration, wherein the first opening degree is greater than the second opening degree.

The gear is set to medium, and the first set quantity is greater than the second set quantity; the fifth adjustment module is used to adjust the operating gear of the duct air conditioner to low when the number of insulated rooms is less than the second set quantity and the ratio is less than the set ratio; the sixth adjustment module is used to adjust the operating gear of the duct air conditioner to the second-highest when the number of insulated rooms is between the first set quantity and the second set quantity and the ratio is greater than or equal to the set ratio; the seventh adjustment module is used to adjust the operating gear of the duct air conditioner to medium when the number of insulated rooms is between the first set quantity and the second set quantity and the ratio is less than the set ratio.

[0119] In an optional embodiment, the device further includes a first detection unit, which, after adjusting the opening of the air valve of each of the aforementioned insulated rooms according to the temperature difference value of each of the aforementioned insulated rooms, detects the continuous unoccupied time of each of the aforementioned insulated rooms, and closes the air valve of each of the aforementioned insulated rooms whose continuous unoccupied time exceeds a set time.

[0120] In an alternative embodiment, the device further includes a second detection unit for identifying the insulated rooms using personnel detection sensors for each room before acquiring the current temperature data of the multiple insulated rooms, wherein the personnel detection sensors include at least one of millimeter-wave radar and thermal infrared sensors.
