Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of indoor environment control, and in particular to an indoor environment control method based on a collaborative regulation system and related equipment. BACKGROUND

[0002] With the continuous improvement of people's requirements for the quality of life, the comfort and air quality of the indoor environment are increasingly valued. Abnormal indoor temperature and humidity and excessive VOCs can seriously affect people's health and living experience. Currently, the indoor environment control systems on the market mostly use single devices for regulation, such as using air conditioners or air source heat pumps to regulate temperature, using humidifiers or dehumidifiers to regulate humidity, and using separate exhaust fans or fresh air fans to deal with excessive VOCs and PM2.5. There is a lack of collaborative control among the devices, resulting in low degree of automatic regulation, high energy consumption, and difficulty in achieving balanced control of constant temperature, constant humidity, constant oxygen, and constant cleanliness.

[0003] To sum up, the technical problems in the related art need to be improved. SUMMARY

[0004] The main purpose of the embodiments of the present application is to propose an indoor environment control method based on a collaborative regulation system and related equipment, which can automatically adjust the exhaust fan speed and the opening degree of the air valve, achieve constant indoor temperature, humidity, and VOC content, improve the quality of the indoor environment, and reduce energy consumption.

[0005] To achieve the above-mentioned purpose, one aspect of the embodiments of the present application proposes an indoor environment control method based on a collaborative regulation system. The collaborative regulation system includes a fresh air fan, an air filter, a heat exchanger, a humidifier, a plurality of air system terminal devices, an exhaust fan, and a controller. One end of the air filter is connected to the fresh air fan, and the other end of the air filter is connected to the heat exchanger. One end of the humidifier is connected to the heat exchanger, and the other end of the humidifier is connected to a plurality of air system terminal devices. The air system terminal devices are respectively arranged in each room. The room is provided with a sensor module. The air system terminal devices include air valves or air fans. A plurality of air system terminal devices are respectively connected to the exhaust fan. The fresh air fan, the air system terminal devices, the exhaust fan, and the sensor module are respectively connected to the controller in communication. The control method includes the following steps: Obtaining indoor environment data through the sensor module; Regulating and controlling according to the indoor environment data to obtain a target indoor environment.

[0006] In some embodiments, the controller obtains data of the sensor module, including temperature sensor data, humidity sensor data, and air quality sensor data. The temperature sensor data comprises a first temperature threshold and a second temperature threshold; The humidity sensor data comprises a first humidity threshold and a second humidity threshold; The air quality sensor data comprises a first air quality, a second air quality and a third air quality.

[0007] In some embodiments, the controller controls the air speed of the exhaust fan comprises a low gear, a medium gear and a high gear; When the room temperature is less than the first temperature threshold, the room humidity is less than the first humidity threshold or the room air quality is the first air quality, the exhaust fan opens the low gear; When the room temperature is less than the second temperature threshold and greater than or equal to the first temperature threshold, the room humidity is less than the second humidity threshold and greater than or equal to the first humidity threshold or the room air quality is the second air quality, the exhaust fan opens the medium gear; When the room temperature is greater than or equal to the second temperature threshold, the room humidity is greater than or equal to the second humidity threshold or the room air quality is the third air quality, the exhaust fan opens the high gear.

[0008] In some embodiments, the regulating according to the indoor environment data to obtain a target indoor environment comprises the following steps: The controller first determines whether the room needs to be controlled by the high gear of the exhaust fan according to the temperature sensor data, the humidity sensor data or the air quality sensor data; When the indoor environment of the room does not need to be controlled by the high gear of the exhaust fan, the controller determines whether the room needs to be controlled by the medium gear of the exhaust fan; When the indoor environment of the room does not need to be controlled by the medium gear of the exhaust fan, the controller determines whether the room needs to be controlled by the low gear of the exhaust fan until the target indoor environment is obtained.

[0009] In some embodiments, the regulating according to the indoor environment data to obtain a target indoor environment further comprises the following steps: When the medium gear of the exhaust fan is controlled, the controller determines whether the room needs to be controlled by the low gear of the exhaust fan according to the temperature sensor data, the humidity sensor data or the air quality sensor data.

[0010] In some embodiments, the regulating according to the indoor environment data to obtain a target indoor environment further comprises the following steps: When the exhaust fan is controlled at its low speed setting, the controller determines the room to be controlled at its high speed setting based on the temperature sensor data, the humidity sensor data, or the air quality sensor data.

[0011] In some embodiments, the controller controls the opening degree of the air valve or the rotational speed of the fan in the air system terminal device using a PID algorithm based on the temperature sensor data and the target temperature data.

[0012] In some embodiments, the step of adjusting the indoor environment based on the indoor environment data to obtain the target indoor environment further includes the following steps: When the motor of the air valve maintains a constant speed and its power decreases, the controller stops controlling the terminal equipment of the air system through the PID algorithm, shuts down the exhaust fan, and the fresh air fan operates at its maximum speed. When the motor power of the air valve reaches the target power, the controller controls the terminal equipment of the air system through the PID algorithm.

[0013] To achieve the above objectives, another aspect of this application proposes a control system for an indoor environment based on a coordinated adjustment system. The coordinated adjustment system includes a fresh air unit, an air filter, a heat exchanger, a humidifier, multiple air system terminal devices, an exhaust fan, and a controller. One end of the air filter is connected to the fresh air unit, and the other end is connected to the heat exchanger. One end of the humidifier is connected to the heat exchanger, and the other end is connected to the multiple air system terminal devices. The multiple air system terminal devices are respectively installed in each room, and each room is equipped with a sensor module. Each air system terminal device includes an air valve or a fan. The multiple air system terminal devices are respectively connected to the exhaust fan. The fresh air unit, the air system terminal devices, the exhaust fan, and the sensor module are all communicatively connected to the controller. The control system includes: A data acquisition module is used to acquire indoor environmental data through the sensor module; The judgment and control module is used to adjust the indoor environment based on the indoor environment data to obtain the target indoor environment.

[0014] To achieve the above objectives, another aspect of this application provides an electronic device, which includes a memory and a processor. The memory stores a computer program, and the processor executes the computer program to implement the method described above.

[0015] The embodiments of this application include at least the following beneficial effects: This application provides a method and related equipment for controlling the indoor environment based on a coordinated regulation system. This solution integrates a fresh air unit, air filter, heat exchanger, humidifier, multiple sets of air system terminal equipment, exhaust fan, and controller. By deploying sensor modules in each room, a closed-loop control system is constructed. After the air is introduced by the fresh air unit, purified by the filter, and humidified by the heat exchanger and humidifier, it is precisely delivered to each room by the air system terminal equipment. At the same time, combined with the exhaust and return air circulation functions of the exhaust fan, efficient replacement and circulation purification of indoor and outdoor air are achieved. With the controller performing dynamic regulation based on the indoor environmental data collected in real time by the sensor modules, indoor pollutants such as VOCs or PM2.5 can be quickly removed, and excess heat and cold can be transferred in a timely manner. This effectively solves the problems of slow response and asynchronous temperature, humidity, and air quality regulation in traditional air conditioning systems. It can make the indoor temperature, humidity, and pollution level quickly approach the human comfort range, and ultimately achieve the goal of a stable indoor environment with constant temperature, constant humidity, and constant oxygen, greatly improving indoor air quality and human living comfort.

[0021] Before providing a detailed description of the embodiments of this application, some of the nouns and terms involved in the embodiments of this application will be explained first. The nouns and terms involved in the embodiments of this application are subject to the following interpretations.

[0022] EEPROM: Electrically Erasable Programmable Read-Only Memory. Data can be erased and rewritten without disassembling the device or exposing it to ultraviolet light; it is powered on. Data is not lost after power is off. It is commonly used to store configuration information for home appliances and industrial control equipment.

[0023] Figure 1 This is an optional flowchart of an indoor environment control method based on a coordinated adjustment system provided in this application embodiment. Figure 1 The method may include, but is not limited to, steps S110 to S120.

[0024] Step S110: Acquire indoor environmental data through the sensor module; Step S120: Adjust the indoor environment based on the indoor environmental data to obtain the target indoor environment.

[0025] Steps S110 to S120, as illustrated in this embodiment, integrate a fresh air unit, air filter, heat exchanger, humidifier, multiple air system terminal devices, exhaust fan, and controller through a coordinated adjustment system. The components are connected sequentially: one end of the air filter is connected to the fresh air unit, and the other end is connected to the heat exchanger; one end of the humidifier is connected to the heat exchanger, and the other end is connected to the air system terminal devices distributed in each room. Each room is equipped with a sensor module. The air system terminal devices include air valves or fans, and each terminal device is connected to the exhaust fan. Simultaneously, the fresh air unit, air system terminal devices, exhaust fan, and sensor module are all connected to the controller. The communication connection is established; the control method of the coordinated adjustment system is as follows: the indoor environmental data is collected in real time by the sensor module in the room, and the controller coordinates and regulates each device based on the acquired environmental data. The system uses a fresh air fan to introduce outdoor fresh air, an air filter to filter and purify the air, a heat exchanger to regulate the air temperature, and a humidifier to regulate the air humidity. The treated air is then delivered to each room through the terminal equipment of the air system. At the same time, the exhaust fan removes the indoor pollutants or heat and cold, so as to quickly bring the indoor temperature, humidity and pollution level close to the human comfort range, and finally achieve the control goal of constant temperature, constant humidity and constant oxygen.

[0026] In some embodiments, the sensor module is responsible for collecting three types of core indoor environmental data, including temperature sensor data, humidity sensor data, and air quality sensor data. The temperature sensor data is set with a first temperature threshold and a second temperature threshold; the humidity sensor data is set with a first humidity threshold and a second humidity threshold; and the air quality sensor data is set with three air quality levels: a first air quality level, a second air quality level, and a third air quality level. These thresholds and levels together constitute the basis for the controller to judge the indoor environmental status. The air quality sensor data includes data acquired by VOC, PM2.5, carbon dioxide, or oxygen sensors. The controller presets three fan speeds (low, medium, and high) for the exhaust fan and can intelligently switch the exhaust fan speed based on the environmental data fed back by the sensor module.

[0027] When the indoor environmental data fed back by the sensor module meets any of the following conditions, the controller will control the exhaust fan to turn on at a low speed: the room temperature is less than a first temperature threshold, the room humidity is less than a first humidity threshold, or the room air quality is at a first air quality level. In this mode, the exhaust fan operates at a lower speed, which can reduce energy consumption while maintaining basic indoor air circulation, and is suitable for scenarios where the indoor environment is close to the comfort range.

[0028] When the indoor environmental data fed back by the sensor module meets any of the following conditions, the controller will switch the exhaust fan to medium speed: the room temperature is less than the second temperature threshold and greater than or equal to the first temperature threshold; the room humidity is less than the second humidity threshold and greater than or equal to the first humidity threshold; or the room air quality is at the second air quality level. This fan speed setting improves the efficiency of indoor and outdoor air exchange, accelerates the removal of slightly excessive indoor pollutants or excess heat and cold, and gradually brings the indoor environment closer to a comfortable range.

[0029] When the indoor environmental data fed back by the sensor module meets any of the following conditions, the controller will control the exhaust fan to turn on high speed: the room temperature is greater than or equal to the second temperature threshold, the room humidity is greater than or equal to the second humidity threshold, or the room air quality is at the third air quality level. In high speed mode, the exhaust fan operates at maximum power, enabling rapid removal of indoor pollutants or excess heat and cold, quickly improving the harsh indoor environment, and rapidly bringing indoor temperature, humidity, and pollution levels closer to the human comfort range, ultimately achieving the control goals of constant temperature, constant humidity, and constant oxygen.

[0030] The exhaust fan has three operating levels set according to the hierarchical control logic. The trigger conditions for each level are directly related to indoor environmental parameters. The threshold values ​​for temperature, humidity, and VOC pollution index are all preset values, or can be set by the user and automatically stored in the EEPROM. Preferably, setting 1 is the human comfort zone setting, where the exhaust fan operates at this setting when any of the following conditions are met: indoor temperature less than 25 degrees Celsius, relative humidity less than 50%, and VOC pollution index at the first air quality level; setting 2 is the non-comfort zone setting, where the exhaust fan switches to this setting when any of the following conditions are met: indoor temperature less than 28 degrees Celsius and higher than or equal to the comfort zone temperature threshold of 25 degrees Celsius, relative humidity less than 70% and higher than or equal to the comfort zone humidity threshold of 50%, and VOC pollution index at the second air quality level; setting 3 is the non-comfort zone setting, where the exhaust fan switches to this setting when any of the following conditions are met: indoor temperature greater than or equal to 28 degrees Celsius, relative humidity greater than or equal to 70%, and VOC pollution index at the third air quality level. This tiered speed adjustment achieves efficient removal of indoor pollutants and heat / cold, pushing the indoor environment closer to the comfort zone.

[0031] In some embodiments, such as Figure 2 As shown, Figure 2 The outdoor air is returned by the fresh air unit and the return air unit, then filtered, and then turned into air at a constant temperature through the heat exchanger. The humidified air is then mixed and connected to the air valves in each room through pipes. Finally, part of the air is discharged to the outside through the exhaust fan, and part of it is returned to the air filter through the return air unit. This process can both replenish the outdoor fresh air and continuously circulate and filter the indoor air.

[0032] The opening of the damper is adjusted from 0-100% via a 0-10V signal. The larger the damper opening, the greater the airflow, and the more cooling or heating energy flows into the room. The room temperature is automatically regulated by controlling the damper opening. Alternatively, the cooling capacity of each room can be controlled by a single fan; the higher the fan speed, the more cooling or heating energy flows into the room. The fan can be an AC motor with several speed settings or a variable-speed DC motor.

[0033] In some embodiments, such as Figure 3 As shown, Figure 3 The core control logic of the coordinated adjustment system revolves around the dynamic adjustment of the exhaust fan at multiple speeds. Through environmental data collected by the sensor module and intelligent judgment by the controller, the indoor temperature, humidity, and pollution level are rapidly approached towards the target comfort zone.

[0034] Specifically, during exhaust fan operation, temperature, humidity, and air quality sensors distributed throughout the rooms continuously collect indoor environmental data and transmit it to the controller in real time. The controller first makes a comprehensive judgment based on this data. If it detects that the indoor temperature deviates significantly from the target value, the humidity is too high, or the concentration of pollutants such as VOCs and PM2.5 exceeds the standard, requiring rapid removal of polluted air or excess heat / cooling, the controller will directly switch the exhaust fan to high-speed operation. High-speed operation maximizes the efficiency of indoor-outdoor air exchange, rapidly reducing indoor pollutant concentrations while accelerating the removal of excess heat or cooling.

[0035] After the exhaust fan runs at high speed for a period of time, the controller continuously receives environmental data from the sensors. If it determines that the indoor environmental parameters have significantly improved and the strong air exchange at high speed is no longer needed, the controller will switch the exhaust fan to medium speed. Medium speed operation is more focused on balancing air exchange efficiency and energy consumption control, maintaining indoor air circulation while avoiding energy waste caused by high-speed operation. While the exhaust fan is at medium speed, the controller does not stop dynamic monitoring and will continue to make secondary judgments based on real-time temperature, humidity, and air quality data. Once it detects that the indoor environmental parameters are stabilizing and continuous operation at medium speed is no longer necessary, it will further switch the exhaust fan to low speed to maintain basic indoor air circulation in a low-power mode.

[0036] When the exhaust fan is in low speed mode, it enters a fine-tuning phase, primarily used to maintain the target state of constant indoor temperature, humidity, and oxygen levels over the long term. However, the controller continues to monitor sensor data with high sensitivity. If fluctuations in the indoor environment are detected, such as increased pollutant concentration due to increased human activity or deviations in indoor temperature and humidity caused by changes in external temperature, the controller will immediately respond by switching the exhaust fan from low speed to high speed, initiating a new round of rapid adjustment. In this way, the high, medium, and low speeds of the exhaust fan form a closed-loop dynamic control mechanism, enabling rapid intervention when environmental parameters deviate significantly, and maintaining low power consumption when parameters are stable, achieving efficient and precise continuous optimization of the indoor environment.

[0037] More specifically, a higher exhaust fan speed will more quickly remove excess cooling or heating, pollutants, and humidity from the room. The program automatically adjusts the exhaust fan speed based on temperature, humidity, and air quality sensor readings, keeping it at a low speed, within the human comfort zone. Simultaneously, when the temperature and humidity are suitable, it automatically maintains a low speed to reduce heat loss and energy consumption. The controller logic is as follows: it first checks if any conditions for high speed are met; only if none are met will it check if medium speed conditions are met. Low speed is only activated when neither high nor medium speed conditions are met. While operating at low speed, the controller returns to the high-speed condition check, continuously cycling through these conditions. When temperature, humidity, and pollution levels are within the human comfort zone (low-speed conditions), the fan operates at low speed or stops, minimizing overall system heat loss and saving energy. At any given time, if any of the temperature, humidity, or pollution levels exceeds the human comfort zone, the exhaust fan will increase its speed when operating at either medium or high speed to quickly remove pollutants or heat and cold, thereby rapidly bringing the temperature, humidity, and pollution levels closer to the human comfort zone and achieving the goal of constant temperature, constant humidity, and constant oxygen.

[0038] In some embodiments, the controller sets a target temperature value, such as 26 degrees Celsius, which is either preset by the program or automatically stored in the EEPROM according to user settings. For each room, based on the difference between the actual temperature and the target temperature, a PID algorithm automatically adjusts the opening of the air damper or the speed of the fan to ensure that the temperature in each room remains stable at the target temperature. For example, if the actual temperature in room 1 is higher than the target temperature, the opening of the air damper or the speed of the motor is reduced to lower the room temperature and achieve the purpose of constant temperature.

[0039] In some embodiments, such as Figure 4As shown, when the window in room 1 (kitchen) is open or the range hood is turned on, the indoor pressure becomes lower than the outdoor pressure, allowing polluted air to enter the room. When a room changes from a normal slightly positive pressure mode to a negative pressure mode, the air resistance of the damper motor decreases, and the motor current and power also decrease.

[0040] The settings are as follows: The motor of damper 1 has a power of A1 at speed A; B2 at speed B, and so on. When the motor speed of damper 1 in room 1 is detected to be A, and the power is A1, if the speed remains unchanged, and the power drops to A2 within one minute, and A1-A2 is greater than A3, then room 1 is determined to have entered a negative pressure state. Here, A3 represents the fan power reduction threshold set by the program. At this time, the program shuts off the exhaust fan, the fresh air fan runs at its maximum speed, the PID algorithm of the damper 1 motor is disabled, and the damper 1 motor runs at its maximum speed. The power corresponding to the maximum speed of the damper motor is compared with the power set by the program. When the power corresponding to the maximum speed is equal to the power set by the program, room 1 is determined to have returned to a slightly positive pressure state. Here, the power set by the program represents the power value under normal slightly positive pressure conditions. The fresh air fan returns to normal control, the exhaust fan turns on, and the damper motor resumes PID algorithm control, thereby achieving the goal of constant cleanliness.
