Description

Technical Field

[0001] The present invention relates to the field of automatic control technology, and in particular to a control method and device for a fresh air blower of an air conditioner. Background Art

[0002] Variable air volume air conditioning system is a kind of full air conditioning system. It is a new technology developed with the comfort and energy-saving requirements of air conditioning. Marine warehouses mostly use fresh air integrated variable air volume air conditioning system due to closed passive room and energy-saving requirements. The air running at sea is highly corrosive. With the passive room air system and closed doors and windows, the carbon dioxide content in the air increases and the oxygen content decreases over time, and the air quality decreases greatly, resulting in low comfort for the human body in the air-conditioned room, so the fresh air system is particularly important. The design scheme of fresh air and return air in the variable air volume system generally adopts fixed ratio control, which greatly helps to improve the indoor air quality. However, because the fresh air load is too large, it often leads to overload operation of the air conditioning system, and the power supply pressure of shipping is relatively large. At the same time, too much fresh air is introduced from the sea, which increases the corrosiveness of the air conditioning system and reduces the service life of the air conditioning system.

[0003] The lack of precise control methods for the demand for fresh air often leads people to manually adjust the air volume according to their own needs. Due to inaccurate control, the human body's demand for fresh air cannot be met, and the human body is in an uncomfortable state for a long time. Conversely, excessive fresh air volume will cause more energy loss.

[0004] Moreover, independent fresh air and return air systems generally use indoor carbon dioxide concentration detection to calculate the fresh air demand, and adjust the fresh air demand by adjusting the fresh air volume of the independent fresh air system. However, it is ignored that the fresh air demand changes with the ambient temperature. The control of the fresh air and return air integrated warehouse is too rough, and the energy saving and comfort are low.

[0005] To address the above-mentioned problems, no effective solution has been proposed yet. Summary of the invention

[0037] According to an embodiment of the present invention, a method embodiment of a method for controlling a fresh air blower of an air conditioner is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0038] Figure 2 is a flow chart of a control method for a fresh air blower of an air conditioner according to an embodiment of the present invention. Figure 2 As shown, the method comprises the following steps:

[0039] Step S202, when it is determined that the first cumulative time of the fresh air blower of the air conditioner is on and running reaches the first predetermined time, the current set temperature of the air conditioner is obtained, wherein the first predetermined time is the time corresponding to the time when the air conditioner is turned on and running until the environmental indicators of the room where it is located tend to stabilize, and the environmental indicators include at least one of the following: oxygen concentration value, indoor temperature.

[0040] In this embodiment, it can be determined whether the air conditioner has reached a stable state after being turned on. By obtaining the current set temperature and comparing it with the first predetermined time, it can be determined whether the air conditioner has stabilized the indoor environmental indicators after running for a period of time. This can ensure that the air conditioner can reach the set target temperature or oxygen concentration value during operation, thereby improving the efficiency and energy-saving performance of the air conditioner. At the same time, the working mode of the air conditioner can be adjusted in time by monitoring changes in environmental indicators to maintain the comfort and safety of the indoor environment.

[0041] It should be noted that the above-mentioned fresh air fan is an important component of the air conditioner. Its main function is to introduce fresh air from outdoors into the room, keep the indoor air fresh and circulating, help eliminate indoor odors, moisture and pollutants, improve air quality, and enhance living comfort. The fresh air fan is usually composed of motors, fans, filters and other components. It generates airflow through operation to introduce fresh air into the room.

[0042] Optionally, the indoor environmental indicators may include, but are not limited to, parameters such as indoor temperature, humidity, wind speed, indoor ventilation rate, air change frequency, oxygen concentration value, and airflow distribution.

[0043] Step S204, determining the minimum oxygen concentration value required by the target object in the room where the air conditioner is located in each operating mode of the air conditioner according to the current set temperature, wherein the operating mode includes at least: a normal activity mode, a sports mode and a sleep mode.

[0044] In this embodiment, the minimum oxygen concentration value required for the target object in the room where the air conditioner is located in each operating mode of the air conditioner is determined according to the current set temperature, which can help the air conditioner to adjust the air circulation according to the indoor temperature and activity status, so as to ensure the quality and comfort of the indoor air. Under different operating modes, the degree of human activity is different, so the required oxygen concentration value will also be different. By setting the corresponding minimum oxygen concentration value, the air conditioner can adjust the air circulation according to different operating modes, so as to ensure the freshness and comfort of the indoor air and enhance the user experience.

[0045] Step S206: selecting a target operating mode from various operating modes according to the current state of the target object.

[0046] In this embodiment, the most suitable operating mode can be selected according to the current state of the air conditioner fresh air fan to achieve more efficient operation. For example, the cooling mode can be selected when the indoor temperature is high, and the fresh air mode can be selected when the air quality is poor. By dynamically adjusting the operating mode, the energy efficiency performance of the equipment can be improved while ensuring the comfort and air quality of the indoor environment.

[0047] Step S208, controlling the fresh air fan according to the current indoor oxygen concentration value in the room where the air conditioner is located and the corresponding selected oxygen concentration value in the target operation mode.

[0048] In this embodiment, the operation of the fresh air fan can be automatically adjusted according to the indoor oxygen concentration value and the set value under the target operation mode to ensure the freshness and comfort of the indoor air. By monitoring the indoor oxygen concentration value, the system can adjust the operation of the fresh air fan in time to maintain the quality of the indoor air, which can effectively improve the energy efficiency of the air-conditioning system, reduce energy consumption, and also enhance the comfort of the user.

[0049] As can be seen from the above, in the embodiment of the present invention, when it is determined that the first accumulated time of the fresh air fan of the air conditioner is turned on and running reaches the first predetermined time, the current set temperature of the air conditioner is obtained, wherein the first predetermined time is the time corresponding to the time when the air conditioner is turned on and running until the environmental indicators of the room where it is located tend to be stable, and the environmental indicators include at least one of the following: oxygen concentration value, indoor temperature; according to the current set temperature, the minimum oxygen concentration value required by the target object in the room where the air conditioner is located in each operating mode of the air conditioner is determined, wherein the operating mode at least includes: regular activity mode, exercise mode and sleep mode; according to the current state of the target object, a target operating mode is selected from each operating mode; according to the current indoor oxygen concentration value of the room where the air conditioner is located and the corresponding selected oxygen concentration value under the target operating mode, the fresh air fan is controlled, so as to achieve the purpose of automatically adjusting the air volume of the fresh air fan outlet in the room by means of function model and oxygen concentration sensor, and at the same time, through real-time detection and compensation adjustment according to feedback information, a compensation oxygen supplement correction control scheme is adopted according to the air conditioner setting mode to automatically control the air volume, thereby realizing the technical effect of intelligent control of the air conditioning system and improving the efficiency and performance of the system.

[0050] The technical solution provided by the embodiment of the present invention solves the technical problem in the related art that the fresh air volume in the air-conditioning fresh air control system does not match the change in indoor ambient temperature, which easily causes energy loss.

[0051] According to the above embodiment of the present invention, determining that the first cumulative duration of the fresh air fan of the air conditioner is on and running reaches the first predetermined duration includes: after receiving the fresh air start-up instruction, triggering the fresh air fan to enter the start-up operation state according to the fresh air fan start-up instruction; after determining that the fresh air fan enters the start-up operation state according to the fresh air fan start-up instruction, counting the first cumulative duration of the fresh air fan start-up operation until the first cumulative duration reaches the first predetermined duration.

[0052] In this embodiment, it can be ensured that the fresh air fan can operate normally according to the predetermined duration after receiving the power-on command, thereby ensuring the stability of air quality and improving the efficiency of the air-conditioning system. At the same time, by counting the power-on operating time of the fresh air fan, possible problems with the fresh air fan can be discovered and dealt with in time to ensure the normal operation of the air-conditioning system.

[0053] Specifically, turn on the air conditioner manually, set the required indoor temperature (set the temperature of the air conditioner to S), turn on the fresh air fan, and after the fresh air fan is turned on, it enters the initial mode (i.e., the turned-on running state) and counts the first cumulative running time of the fresh air fan, among which the normal comfort mode is the initial running mode after the fresh air fan is turned on. After a period of time, the first cumulative time reaches the first predetermined time, and the indoor oxygen concentration value tends to be stable and the indoor temperature tends to be stable.

[0054] According to the above embodiment of the present invention, the minimum oxygen concentration value required for the target object in the room where the air conditioner is located in each operating mode of the air conditioner is determined according to the current set temperature, including: inputting the current set temperature into an oxygen concentration value prediction model, and processing the current set temperature using the oxygen concentration value prediction model to obtain the minimum oxygen concentration value in each operating mode, wherein the oxygen concentration value prediction model is a model trained by machine learning using multiple sets of training data, and each of the multiple sets of training data includes: a sample set temperature and a sample minimum oxygen concentration value corresponding to the sample set temperature.

[0055] It should be noted that the above-mentioned oxygen concentration value prediction model is a mathematical model used to predict future oxygen concentration values. It is usually based on historical oxygen concentration data and other related factors (such as temperature, humidity, wind direction, etc.) for modeling and prediction. Among them, commonly used models include linear regression models, time series models, neural network models, etc., which can be trained to learn the relationship between oxygen concentration values ​​and other factors and use them to predict future oxygen concentration values.

[0056] In this embodiment, inputting the current set temperature into the oxygen concentration value prediction model can help the system predict the minimum oxygen concentration value under the current set temperature. The system can automatically adjust the working state of the fresh air fan according to the requirements under different operating modes to ensure that the oxygen concentration in the indoor air is within a safe range. By predicting the oxygen concentration value, the system can make timely adjustments to ensure good indoor air quality, protect people's health, improve the efficiency and energy saving of the air-conditioning system, and also enhance the user's comfort.

[0057] Figure 3 is a flow chart of an optional control method of a fresh air blower of an air conditioner according to an embodiment of the present invention, such as Figure 3 As shown, at this stage, the main control system of the air conditioner fresh air fan automatically calculates the minimum oxygen concentration required for the human body (comfort) in different modes according to the current set temperature through a function model (i.e., an oxygen concentration prediction model). For example, when the current temperature S is set, the indoor oxygen concentration is A, the minimum oxygen concentration required by the human body in the normal comfort mode is b1, the minimum oxygen concentration required by the human body in the exercise mode is a1, and the minimum oxygen concentration required by the human body in the sleep mode is c1.

[0058] It should be noted that under set temperature conditions, specific environmental modes can be further refined. For example, the sleep mode can determine the air volume index based on the length of time a person enters sleep, and the value of the minimum required oxygen concentration will also change accordingly, which can make the control more precise and the corresponding effect more significant.

[0059] According to the above embodiment of the present invention, a target operating mode is selected from various operating modes according to the current state of the target object, including: triggering an image acquisition module in the room where the air conditioner is located to acquire an image of the target object in the room where the air conditioner is located; analyzing the image to obtain the current state of the target object; and selecting the target operating mode from various operating modes using the current state as an index.

[0060] In this embodiment, an image of a target object in the room where the air conditioner is located is collected by an image acquisition module, and the image is analyzed to obtain the current state of the target object. For example, when there is someone in the room, it is in an "occupied state", and when there is no one in the room, it is in an "unoccupied state". Then, based on the current state as an index, a target operating mode is selected from various operating modes, thereby realizing intelligent control of the operation of the air-conditioning fresh air fan, improving energy efficiency and comfort. The air-conditioning fresh air fan can adjust its operation more intelligently according to actual conditions, thereby improving user experience and energy-saving effects.

[0061] According to the above embodiment of the present invention, the fresh air fan is controlled according to the current indoor oxygen concentration value in the room where the air conditioner is located and the selected oxygen concentration value corresponding to the target operation mode, including: sending a data request instruction to the oxygen concentration monitoring component in the room where the air conditioner is located; obtaining the current indoor oxygen concentration value fed back by the oxygen concentration monitoring component based on the data request instruction; determining the selected oxygen concentration value under the target operation mode; and controlling the fresh air fan according to the current indoor oxygen concentration value and the selected oxygen concentration value.

[0062] It should be noted that the above-mentioned oxygen concentration monitoring component is usually a sensor used to monitor the indoor oxygen concentration and transmit data to the air-conditioning system. The air-conditioning system can adjust the supply and circulation of indoor air according to the oxygen concentration to ensure the quality and comfort of indoor air.

[0063] In this embodiment, by monitoring and obtaining the indoor oxygen concentration value, determining the selected oxygen concentration value under the target operation mode, and controlling the operation of the fresh air fan according to these values ​​to ensure the quality and comfort of the indoor air, the intelligent control of the air-conditioning fresh air fan can be realized, so that the fresh air volume can be adjusted according to actual needs, the air quality can be improved, and the comfort of the indoor environment can be enhanced.

[0064] Figure 4 is a schematic plan view of chamber oxygen supplementation according to an embodiment of the present invention. Figure 4 As shown, it includes equipment such as oxygen concentration sensors, air valves, fresh air fans and air conditioners, a variable air volume fresh air integrated main unit and multiple chambers. Each chamber contains a variable air volume indoor unit. Different chambers can choose different modes. At the same time, the chamber is connected to an oxygen content sensor (i.e., an oxygen concentration monitoring component) and an air valve (to adjust the air volume at the inlet and outlet).

[0065] Optionally, the oxygen content sensor may be an oxygen concentration monitoring component or other oxygen concentration detection device.

[0066] like Figure 3 As shown, according to the current specific indoor environment, after selecting the mode to be operated (normal comfort, exercise, sleep, etc.), a data request instruction is sent to the indoor oxygen concentration sensor. The indoor oxygen concentration sensor obtains the current indoor oxygen concentration value, determines the selected oxygen concentration value under the target operating mode, and then controls the fresh air fan.

[0067] It should be noted that in addition to using an oxygen concentration sensor to measure the oxygen concentration as a monitoring indicator, a carbon dioxide concentration sensor can also be used to measure the carbon dioxide concentration as an indicator. When the monitoring indicator changes, the judgment mechanism changes, which has no effect on the final effect.

[0068] According to the above embodiment of the present invention, the fresh air fan is controlled according to the current indoor oxygen concentration value and the selected oxygen concentration value, including: comparing the current indoor oxygen concentration value with the selected oxygen concentration value to obtain a comparison result; when the comparison result indicates that the current indoor oxygen concentration value is greater than the selected oxygen concentration value, controlling the air valve of the fresh air fan to increase so as to increase the air volume at the air inlet and outlet of the fresh air fan; when the comparison result indicates that the current indoor oxygen concentration value is equal to the selected oxygen concentration value, keeping the air valve of the fresh air fan unchanged so that the fresh air fan operates according to the current air volume; when the comparison result indicates that the current indoor oxygen concentration value is less than the selected oxygen concentration value, controlling the air valve of the fresh air fan to decrease so as to reduce the air volume at the air inlet and outlet of the fresh air fan.

[0069] It should be noted that the air valve of the above-mentioned fresh air fan is a device used to control the fresh air entering the room. It is usually installed at the air outlet of the fresh air fan. By adjusting the opening and closing degree of the air valve, the flow and speed of the fresh air can be controlled, thereby realizing the circulation and ventilation of the indoor air. The air valve of the fresh air fan is usually made of metal or plastic, and has the characteristics of high temperature resistance, waterproof and dustproof, etc., which can ensure the normal operation of the fresh air fan and effectively improve the indoor air quality.

[0070] In this embodiment, based on the comparison result between the current indoor oxygen concentration value and the selected oxygen concentration value, the air volume of the fresh air fan is automatically adjusted to maintain the freshness and comfort of the indoor air. Real-time monitoring and adjustment of the indoor oxygen concentration can be achieved to ensure the excellent indoor air quality and improve the comfort of the living environment. It can effectively save energy and improve the operating efficiency of the air-conditioning system.

[0071] Figure 5 is a schematic diagram of dynamic oxygen supplementation at different ambient temperatures according to an embodiment of the present invention, such as Figure 5As shown in the figure, under different modes, the function model of temperature and the minimum oxygen concentration required by the human body (for comfort) is that the higher the temperature, the lower the minimum oxygen content required by the human body. Under intense exercise, the human body's oxygen consumption increases, and the minimum oxygen content required by the human body under sleep is relatively small.

[0072] Specifically, it is determined whether the current oxygen concentration value A (i.e., the current indoor oxygen concentration value) is equal to the oxygen concentration values ​​a1, b1, c1 (i.e., the selected oxygen concentration value) of the selected mode at the current temperature as follows: In case 1, if A is equal to a1 / b1 / c1, the air valves of the inlet and outlet ducts of the fresh air fan in the room are fixed and continue to operate according to the current inlet and outlet air volume; In case 2, if the current indoor oxygen concentration A is greater than the oxygen concentration values ​​a1 / b1 / c1 of the selected mode at the current temperature S, the air valves of the inlet and outlet ducts of the fresh air fan in the room are reduced, and the inlet and outlet air volume is reduced until Until the current oxygen concentration value A is equal to the oxygen concentration value a1 / b1 / c1 of the selected mode at the current temperature S; Case three, if the current indoor oxygen concentration A is less than the oxygen concentration value a1 / b1 / c1 of the selected mode at the current temperature, the air valves of the inlet and outlet ducts of the fresh air fan in the room are increased, and the inlet and outlet air volume is increased until the current oxygen concentration value A is equal to the oxygen concentration value a1 / b1 / c1 of the selected mode at the current temperature S. Feedback and adjustment are performed once at each time interval T to ensure that the oxygen concentration in the room is the minimum required oxygen concentration value under human comfort conditions.

[0073] It should be noted that the above-mentioned feedback time interval can be adjusted with different timeliness, which can ensure that the system monitors and adjusts the current oxygen concentration value in a timely manner, thereby ensuring that the oxygen concentration in the room is always maintained at the minimum concentration required for human comfort. Through regular feedback and adjustment, the system can respond to changes in oxygen concentration in a timely manner to ensure the stability and comfort of indoor air quality. Different feedback time intervals can be adjusted according to actual conditions to meet the needs of different scenarios.

[0074] In addition, it should be noted that by studying and analyzing the relationship between human oxygen consumption and human activities under different temperature conditions, conducting data analysis and establishing a mathematical model, this model can be used in the information processing feedback logic. Under different set temperatures, the unit can automatically identify the environmental mode according to the amount of human oxygen consumption per unit time, and automatically adjust the air volume, which is comfortable and energy-saving, and can make control more accurate and adjustment more intelligent and convenient.

[0075] The technical solution provided by the above-mentioned embodiment of the present invention solves the following problems: 1) Solve the problem of quantitative output of fresh air volume and inaccurate adjustment of traditional fresh air system; 2) Solve the problem of energy loss caused by mismatch between fresh air volume and indoor ambient temperature change; 3) Solve the special environment of shipping, accurately control the fresh air in the warehouse and ensure the comfort of personnel. At the same time, it has the following beneficial effects: 1) Improve indoor air quality. By accurately controlling the fresh air volume, the freshness and cleanliness of indoor air can be ensured, the pollutant content in indoor air can be effectively reduced, and the health level of personnel can be improved; 2) Energy saving and emission reduction. By matching the fresh air volume and indoor ambient temperature changes, energy waste can be effectively reduced, energy consumption can be reduced, and energy consumption and carbon dioxide emissions can be reduced; 3) Improve comfort. In the special environment of shipping, accurate control of the fresh air volume in the warehouse can ensure the comfort of the crew in the cabin and improve work efficiency and production benefits.

[0076] From the above, it can be seen that in the embodiments of the present invention, in different compartments, under the cooling or heating temperature conditions set by the air conditioner, according to the different indoor temperatures and the needs of the specific environment, by comparing the current indoor oxygen concentration value with the oxygen concentration value required by the human body (under comfortable conditions), the air volume of the fresh air fan outlet in the room is automatically adjusted by means of function models and oxygen concentration sensors; through real-time detection feedback compensation adjustment, automatic (active) control of the fresh air fan air volume is achieved, precise fresh air volume delivery, reduced air conditioning and fresh air fan energy loss, and better improved human comfort when the indoor air conditioner is turned on; according to the air conditioning setting mode, the control scheme is corrected by compensating for oxygen supplementation to ensure that the human body's supply needs are met in the specific environment of the cabin and the fatigue cycle of offshore operations is extended.

[0077] That is, the above technical solution provided by the embodiment of the present invention comprehensively considers various factors, adopts appropriate adjustment and control strategies, and advanced sensor technology, can realize intelligent control, can improve the indoor environmental quality, save energy, and ensure the comfort of personnel, which is of great significance for promoting the sustainable development of the shipping industry.
