Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and in particular to a fresh air supply control method, device, equipment and medium. Background Art

[0002] With the improvement of building airtightness and the growth of people's requirements for indoor environmental quality, air conditioning fresh air supply technology has received widespread attention and development. In the early days, air conditioning systems mainly focused on regulating indoor temperature and humidity, while ignoring the freshness of indoor air. As time went on, researchers gradually realized the importance of fresh air to the indoor environment and began to integrate fresh air supply systems into air conditioning technology. Since the air volume of fresh air directly affects the circulation, temperature distribution and energy efficiency of indoor air, in order to meet different indoor environments and usage requirements, researchers began to explore how to optimize the fresh air supply system through air volume control to ensure that the fresh air reaches suitable temperature and humidity conditions before entering the room.

[0003] At present, in the fresh air supply system, the collected indoor carbon dioxide concentration is generally used to predict and control the fresh air volume of the air conditioner. However, relying solely on the indoor carbon dioxide concentration to predict and control the fresh air volume of the air conditioner ignores the impact of the fresh air volume on the indoor environment. For example, when the temperature of the external space is high, the fresh air function will simultaneously cause the temperature of the indoor space to rise, which often makes it difficult to achieve the best indoor environment control. In particular, when the air volume needs to be dynamically adjusted according to the indoor environment, it often makes it difficult to achieve the optimal temperature when controlling the indoor environment. Summary of the invention

[0004] The present invention provides a fresh air supply control method, device, equipment and medium, which are used to solve the defect in the prior art that the fresh air volume brings an impact of the external space to the indoor environment, making it difficult to achieve the best indoor environment regulation. The air supply volume can be accurately and reasonably controlled according to actual conditions, thereby effectively improving the indoor air quality and creating a healthy indoor air environment for users.

[0005] The present invention provides a fresh air supply control method, comprising: obtaining the indoor ambient temperature when the air conditioner is in operation; determining whether the current indoor ambient temperature reaches the set temperature of the air conditioner; obtaining wind speed information and time information when the current indoor ambient temperature reaches the set temperature; determining the fresh air volume according to the wind speed information and time information; and controlling the operation of the air conditioner according to the fresh air volume.

[0006] It should be noted that after controlling the operation of the air conditioner, the indoor ambient temperature is obtained so that timely and accurate response can be made based on the comparison results between the current indoor ambient temperature and the set temperature. When it is detected that the current indoor temperature is stable at the set value, the heat generation and loss in the room is balanced with the cooling or heating effect of the air conditioner. Therefore, the fresh air volume is determined by obtaining the wind speed and time information, so as to accurately and reasonably introduce fresh air according to the actual situation, thereby effectively improving the indoor air quality and creating a healthy indoor air environment for users.

[0007] A fresh air supply control method provided by the present invention determines the fresh air volume according to wind speed information and time information, including: determining, according to the time information, the duration of receiving a temperature control instruction to control the air conditioner to operate to the current indoor ambient temperature; obtaining, according to the wind speed information, a fan speed corresponding to the current indoor ambient temperature; and obtaining the fresh air volume according to the duration, the fan speed corresponding to the current indoor ambient temperature and a preset time management coefficient.

[0008] It should be noted that the duration information can reflect the entire heat exchange process from the beginning of temperature adjustment to the current moment. By determining the duration of receiving the temperature control command to control the air conditioner to the current indoor ambient temperature, the time dimension of the air conditioner operation is taken into consideration, so that the determination of the fresh air volume is more in line with the actual changes in the indoor environment; the real-time fan speed reflects the current operating intensity of the air-conditioning system. The fan speed can be used to determine whether the air conditioner is actively circulating indoor air, so as to determine whether the fresh air volume needs to be adjusted accordingly to balance the indoor air quality and temperature regulation effect; the time management coefficient, as a parameter that can be obtained in advance, can be adjusted according to different usage scenarios, air-conditioning equipment characteristics and user needs to ensure air quality; the fresh air volume is determined by comprehensively considering the duration, fan speed and time management coefficient. While avoiding the energy waste that may be caused by the fixed fresh air volume setting, it is ensured that the air quality will not consume too much energy due to excessive processing of fresh air, thereby achieving a balance between energy saving and air quality assurance, and improving the operating efficiency and user experience of the entire system.

[0009] According to a fresh air supply control method provided by the present invention, the fresh air volume is obtained according to the duration, the fan speed corresponding to the current indoor ambient temperature and the preset time management coefficient, including: obtaining the total air volume according to the duration and the fan speed corresponding to the current indoor ambient temperature; obtaining the fresh air volume according to the total air volume, duration and the preset time management coefficient.

[0010] It should be noted that the duration reflects the time span of the air-conditioning operation, and the fan speed reflects the intensity of the current air supply of the air-conditioning. By comprehensively considering the duration and fan speed, the overall situation of indoor air circulation is considered, so as to accurately match the indoor environment's demand for total air volume. After obtaining the total air volume, the fresh air volume is determined in combination with the duration and time management coefficient, so as to accurately determine the fresh air volume that meets the air quality and energy-saving requirements, avoid excessive or insufficient supply of fresh air, and continuously ensure that there is an appropriate amount of fresh air to maintain the freshness and comfort of the indoor air.

[0011] According to a fresh air supply control method provided by the present invention, the fresh air volume is obtained according to the duration, the fan speed corresponding to the current indoor ambient temperature and the preset time management coefficient, including: detecting the indoor ambient noise to obtain the noise intensity; according to the noise intensity, looking up the time management coefficient allocation rule to obtain the time management coefficient corresponding to the noise intensity; wherein the time management coefficient allocation rule is first configured based on different noise intensities and the corresponding required time management coefficients.

[0012] It should be noted that by detecting the noise intensity and dynamically adjusting the time management coefficient, the fresh air volume is affected, so that the fresh air volume is more closely matched with the actual indoor situation. While ensuring the indoor air quality, excessive noise caused by excessive fan speed or excessive fresh air volume is avoided. The air-conditioning system can flexibly adapt to different noise environments and always provide users with a quiet indoor space with good air quality.

[0013] According to a fresh air supply control method provided by the present invention, the operation of an air conditioner is controlled according to the fresh air volume, including: according to the fresh air volume, controlling the air conditioner to operate by increasing the fresh air volume.

[0014] It should be noted that when the indoor temperature is stable at the set value, it means that the thermal comfort demand has been met. At this time, the fresh air volume is increased to more efficiently introduce outdoor fresh air, so that the indoor air forms a more active convection, breaks the possible local air stagnation areas, improves the air circulation conditions of the entire indoor space, and makes the indoor air fresher and more pleasant.

[0015] According to a fresh air supply control method provided by the present invention, the method also includes: when the current indoor ambient temperature has not reached the set temperature, determining whether the current indoor ambient temperature has changed compared with the indoor ambient temperature obtained at a previous moment; if it has changed, controlling the air-conditioning operation according to a preset maximum air volume; otherwise, obtaining wind speed information and time information, and determining the fresh air volume based on the wind speed information and time information, and controlling the air-conditioning operation based on the fresh air volume.

[0016] It should be noted that when it is detected that the current indoor ambient temperature has not reached the set temperature and has changed compared to the previous moment, the air conditioner is controlled to operate at the preset maximum air volume so that the air conditioner can respond quickly to the temperature change and speed up the heat exchange of the indoor air, so as to adjust the indoor temperature to the set value as soon as possible and quickly create a comfortable indoor environment for the user; when it is detected that the current indoor ambient temperature has not reached the set temperature and has not changed, the wind speed and time information are obtained to determine the fresh air volume and control the air conditioner operation to maintain the indoor air quality.

[0017] According to a fresh air supply control method provided by the present invention, the operation of an air conditioner is controlled according to the fresh air volume, including: according to the fresh air volume, controlling the air conditioner to operate by reducing the fresh air volume.

[0018] It should be noted that when the current indoor ambient temperature has not reached the set temperature and the temperature has changed compared to the previous moment, since the primary task of the air conditioner is to quickly adjust the indoor temperature to a comfortable range, the air volume of fresh air can be reduced so that the air conditioning system can concentrate more energy on cooling or heating, speed up the adjustment of indoor temperature, prevent energy from being dispersed in fresh air processing, and enable the limited cooling or heating capacity of the air conditioner to more effectively regulate the indoor air temperature, thereby improving energy utilization efficiency.

[0019] The present invention also provides a fresh air supply control device, including: a temperature acquisition module, which acquires the indoor ambient temperature when the air conditioner is in operation; a temperature detection module, which determines whether the current indoor ambient temperature reaches the set temperature of the air conditioner; an information acquisition module, which acquires wind speed information and time information when the current indoor ambient temperature reaches the set temperature; a fresh air volume determination module, which determines the fresh air volume according to the wind speed information and time information; and a fresh air volume adjustment module, which controls the operation of the air conditioner according to the fresh air volume.

[0020] It should be noted that after the air conditioner is controlled by the temperature acquisition module, the indoor ambient temperature is obtained so that the current indoor environment can be compared with the set temperature through the temperature detection module, so that the fresh air volume control module can make timely and accurate responses according to the comparison results. When it is detected that the current indoor temperature is stable at the set value, the indoor heat generation and loss are balanced with the cooling or heating effect of the air conditioner at this time. Therefore, the fresh air volume is determined by obtaining the wind speed and time information, so as to accurately and reasonably introduce fresh air according to the actual situation, thereby effectively improving the indoor air quality and creating a healthy indoor air environment for users.

[0021] The present invention also provides an electronic device, comprising a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein when the processor executes the computer program, the steps of any of the above-described fresh air supply control methods are implemented.

[0022] The present invention also provides a non-transitory computer-readable storage medium having a computer program stored thereon, and when the computer program is executed by a processor, the steps of any of the above-mentioned fresh air supply control methods are implemented.

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] Figure 1 A flow chart of a fresh air supply control method of the present invention is described, the method comprising: S11, obtaining the indoor ambient temperature when the air conditioner is running; S12, determining whether the current indoor ambient temperature reaches the set temperature of the air conditioner; S13, when the current indoor ambient temperature reaches the set temperature, obtaining wind speed information and time information; S14, determining the fresh air volume according to the wind speed information and the time information; S15, controlling the operation of the air conditioner according to the fresh air volume.

[0027] It should be noted that the step numbers "S1N" in this manual do not represent the order of the fresh air supply control method. Figure 2The fresh air supply control method of the present invention is described.

[0028] Step S11, when the air conditioner is in operation, obtaining the operation status of the air conditioner.

[0029] It should be noted that the air conditioner operation status is generated when the air conditioner is running according to the temperature control instruction. The air conditioner is controlled according to the temperature control instruction to adjust the indoor ambient temperature so that the indoor ambient temperature reaches the set temperature. In this process, by monitoring the indoor ambient temperature, the air conditioner can make a timely and accurate response based on the comparison result between the current temperature and the set temperature. In addition, the air conditioner operation status can be obtained by real-time monitoring or periodically. It can be designed according to actual design requirements and is not further limited here.

[0030] Step S12, determining whether the current indoor ambient temperature reaches the set temperature of the air conditioner.

[0031] Step S13, when the current indoor ambient temperature reaches the set temperature, obtain wind speed information and time information.

[0032] It should be noted that the air conditioner operation mode includes cooling mode and heating mode. In cooling mode, if the current indoor ambient temperature does not reach the set temperature, the indoor ambient temperature is higher than the set temperature. After reaching the set temperature, the air conditioner will control and maintain the indoor ambient temperature until the user adjusts the set temperature of the air conditioner again. Therefore, the cooling mode does not consider the situation where the indoor ambient temperature is lower than the set temperature. Similarly, in heating mode, if the current indoor ambient temperature does not reach the set temperature, the indoor ambient temperature is lower than the set temperature. After reaching the set temperature, the air conditioner will control and maintain the indoor ambient temperature until the user adjusts the set temperature of the air conditioner again. Therefore, the heating mode does not consider the situation where the indoor ambient temperature is higher than the set temperature.

[0033] In addition, the wind speed information includes the fan speed corresponding to the current indoor ambient temperature, and the time information includes the time of receiving the temperature control instruction and the time corresponding to the current indoor ambient temperature.

[0034] In an optional embodiment, the method further includes: when the current indoor ambient temperature does not reach the set temperature, determining whether the current indoor ambient temperature has changed compared to the indoor ambient temperature obtained at a previous moment; if it has changed, controlling the air conditioner to operate according to the preset maximum air volume; otherwise, obtaining wind speed information and time information, and determining the fresh air volume based on the wind speed information and time information, and controlling the air conditioner to operate according to the fresh air volume. It should be added that the wind speed information includes the fan speed corresponding to the current indoor ambient temperature, and the time information includes the time of receiving the temperature control instruction and the time corresponding to the current indoor ambient temperature.

[0035] It should be noted that when it is detected that the current indoor ambient temperature has not reached the set temperature and has changed compared to the previous moment, the air conditioner is controlled to operate at the preset maximum air volume so that the air conditioner can respond quickly to the temperature change and speed up the heat exchange of the indoor air, so as to adjust the indoor temperature to the set value as soon as possible and quickly create a comfortable indoor environment for the user; when it is detected that the current indoor ambient temperature has not reached the set temperature and has not changed, the wind speed and time information are obtained to determine the fresh air volume and control the air conditioner operation to maintain the indoor air quality.

[0036] Step S14, determining the fresh air volume according to the wind speed information and the time information. In this embodiment, determining the fresh air volume according to the wind speed information and the time information includes: determining the duration of receiving the temperature control instruction to control the air conditioner to run to the current indoor ambient temperature according to the time information; obtaining the fan speed corresponding to the current indoor ambient temperature according to the wind speed information; obtaining the fresh air volume according to the duration, the fan speed corresponding to the current indoor ambient temperature and the preset time management coefficient.

[0037] It should be noted that the duration information can reflect the entire heat exchange process from the beginning of temperature adjustment to the current moment. By determining the duration of receiving the temperature control command to control the air conditioner to run to the moment corresponding to the current indoor ambient temperature, the time dimension of the air conditioner operation is taken into consideration, so that the determination of the fresh air volume is more in line with the actual changes in the indoor environment; the real-time fan speed reflects the operating intensity of the current air-conditioning system. The fan speed can be used to determine whether the air conditioner is actively circulating indoor air, so as to determine whether the fresh air volume needs to be adjusted accordingly to balance the indoor air quality and temperature regulation effect; the time management coefficient, as a parameter that can be obtained in advance, can be adjusted according to different usage scenarios, air-conditioning equipment characteristics and user needs to ensure air quality; the fresh air volume is determined by comprehensively considering the duration, fan speed and time management coefficient. While avoiding the energy waste that may be caused by the fixed fresh air volume setting, it is ensured that the air quality will not consume too much energy due to excessive processing of fresh air, thereby achieving a balance between energy saving and air quality assurance, and improving the operating efficiency and user experience of the entire system.

[0038] Specifically, regardless of whether the current indoor ambient temperature reaches the set temperature, the duration can be determined based on the time from receiving the temperature control instruction to reaching the current indoor ambient temperature. Therefore, based on the time information, the duration of receiving the temperature control instruction to control the air conditioner to run to the current indoor ambient temperature is determined, including: based on the time information, obtaining the time corresponding to the time of receiving the temperature control instruction and the current indoor ambient temperature; obtaining the duration based on the time of receiving the temperature control instruction and the time corresponding to the current indoor ambient temperature.

[0039] In addition, the fresh air volume is obtained based on the duration, the fan speed corresponding to the current indoor ambient temperature and the preset time management coefficient, including: obtaining the total air volume based on the duration and the fan speed corresponding to the current indoor ambient temperature; obtaining the fresh air volume based on the total air volume, duration and the preset time management coefficient.

[0040] It should be noted that the duration reflects the time span of the air-conditioning operation, and the fan speed reflects the intensity of the current air supply of the air-conditioning. By comprehensively considering the duration and fan speed, the overall situation of indoor air circulation is considered, so as to accurately match the indoor environment's demand for total air volume. After obtaining the total air volume, the fresh air volume is determined in combination with the duration and time management coefficient, so as to accurately determine the fresh air volume that meets the air quality and energy-saving requirements, avoid excessive or insufficient supply of fresh air, and continuously ensure that there is an appropriate amount of fresh air to maintain the freshness and comfort of the indoor air.

[0041] In addition, the fresh air volume is expressed as: Among them, F represents the fresh air volume; X represents the time management coefficient. The specific acquisition method is described below and will not be repeated here; t represents the duration; G represents the total air volume, , Indicates the fan speed corresponding to the current indoor ambient temperature.

[0042] In an optional embodiment, before obtaining the fresh air volume based on the duration, the fan speed corresponding to the current indoor ambient temperature and the preset time management coefficient, it includes: detecting the indoor ambient noise to obtain the noise intensity; according to the noise intensity, searching for the time management coefficient allocation rule to obtain the time management coefficient corresponding to the noise intensity; wherein the time management coefficient allocation rule is first configured based on different noise intensities and the corresponding required time management coefficients.

[0043] It should be noted that by detecting the noise intensity and dynamically adjusting the time management coefficient, the fresh air volume is affected, so that the fresh air volume is more closely matched with the actual indoor situation. While ensuring the indoor air quality, excessive noise caused by excessive fan speed or excessive fresh air volume is avoided. The air-conditioning system can flexibly adapt to different noise environments and always provide users with a quiet indoor space with good air quality.

[0044] Step S15, controlling the operation of the air conditioner according to the fresh air volume.

[0045] In this embodiment, when the current indoor ambient temperature reaches the set temperature, the air conditioner is controlled to operate according to the fresh air volume, including: according to the fresh air volume, the air conditioner is controlled to operate by increasing the fresh air volume.

[0046] It should be noted that when the indoor temperature is stable at the set value, it means that the thermal comfort demand has been met. At this time, the fresh air volume is increased to more efficiently introduce outdoor fresh air, so that the indoor air forms a more active convection, breaks the possible local air stagnation areas, improves the air circulation conditions of the entire indoor space, and makes the indoor air fresher and more pleasant.

[0047] In an optional embodiment, the air conditioner is controlled to operate according to the fresh air volume, including: increasing the speed of the fresh air fan to increase the fresh air volume; or, appropriately increasing the opening of the fresh air damper, and at the same time, it may be necessary to reduce the opening of the return air damper to keep the total air volume unchanged or adjust it as needed.

[0048] In addition, when the current indoor ambient temperature does not reach the set temperature, the air conditioner operation is controlled according to the fresh air volume, including: according to the fresh air volume, controlling the air conditioner to operate by reducing the fresh air volume.

[0049] It should be noted that when the current indoor ambient temperature has not reached the set temperature and has changed compared to the previous temperature, since the primary task of the air conditioner is to quickly adjust the indoor temperature to a comfortable range, the air volume of fresh air can be reduced so that the air conditioning system can concentrate more energy on cooling or heating, speed up the adjustment of indoor temperature, prevent energy from being dispersed in fresh air processing, and make the limited cooling or heating capacity of the air conditioner more effectively act on indoor air temperature regulation, thereby improving energy utilization efficiency. It should be added that the determination of the fresh air volume can be referred to the following description, and will not be repeated here.

[0050] In an optional embodiment, the air conditioner is controlled to operate in a manner to reduce the fresh air volume according to the fresh air volume, including: lowering the speed of the fresh air fan to reduce the fresh air volume; or, appropriately reducing the opening of the fresh air damper, and at the same time, it may be necessary to increase the opening of the return air damper to keep the total air volume unchanged or adjust it as needed.

[0051] In an optional embodiment, when the air conditioner is controlled to operate according to the fresh air volume, the fresh air volume may be increased, which may affect the indoor ambient temperature to be maintained at the set temperature. Therefore, after the air conditioner is controlled to operate according to the fresh air volume, it also includes: real-time monitoring of the indoor ambient temperature. When the indoor ambient temperature deviates from the set temperature, the heating or cooling power of the air conditioner is adjusted according to the size and direction of the temperature deviation to compensate for the temperature change and restore the indoor ambient temperature to the set temperature.

[0052] It should be noted that the heating or cooling power of the air conditioner can be adjusted according to the size and direction of the temperature deviation. The fuzzy control algorithm PID (proportional-integral-differential) control algorithm can be used to achieve this. According to the historical data of the temperature deviation and the size and direction of the current temperature deviation, the cooling or heating power that the air conditioner needs to adjust can be accurately calculated. For example, the PID control algorithm can quickly respond to temperature deviations through the proportional link, eliminate steady-state errors through the integral link, and predict temperature change trends through the differential link, so as to achieve precise control of indoor temperature.

[0053] In an optional embodiment, before controlling the operation of the air conditioner according to the fresh air volume, it includes: detecting the indoor air quality and the number of people. If the indoor air quality exceeds a preset quality range, and / or the number of people exceeds a preset number of people range, the air conditioner is controlled to operate by increasing the fresh air volume; otherwise, the current operating mode is maintained.

[0054] It should be noted that the preset quality range and the preset number of personnel range can be set according to the actual indoor air quality requirements to be maintained or prior experience, and no further limitation is made here. In addition, controlling the operation of the air conditioner according to the fresh air volume may affect the indoor ambient temperature to be maintained at the set temperature. Therefore, it is also necessary to compensate for the temperature change so that the indoor ambient temperature returns to the set temperature. The specific implementation method can refer to the above description and will not be repeated here.

[0055] To summarize, the embodiment of the present invention obtains the indoor ambient temperature after controlling the operation of the air conditioner, so that timely and accurate response can be made according to the comparison result between the current indoor ambient temperature and the set temperature. When it is detected that the current indoor temperature is stable at the set value, the heat generation and loss in the room is balanced with the cooling or heating effect of the air conditioner at this time. Therefore, the fresh air volume is determined by obtaining the wind speed and time information, so as to accurately and reasonably introduce fresh air according to the actual situation, thereby effectively improving the indoor air quality and creating a healthy indoor air environment for users.

[0063] In this embodiment, when the current indoor ambient temperature does not reach the set temperature, the fresh air volume adjustment module 35 is used to control the air conditioner to operate at an increased fresh air volume according to the fresh air volume.

[0064] In an optional embodiment, the fresh air volume adjustment module 35 is also used to: increase the rotation speed of the fresh air fan to increase the fresh air volume; or, appropriately increase the opening of the fresh air damper, and at the same time may need to reduce the opening of the return air damper to keep the total air volume unchanged or adjust it as needed.

[0065] In addition, when the current indoor ambient temperature does not reach the set temperature, the fresh air volume adjustment module 35 is also used to: control the air conditioner to operate at a reduced fresh air volume according to the fresh air volume.

[0066] In an optional embodiment, the fresh air volume adjustment module 35 is also used to: reduce the rotation speed of the fresh air fan to reduce the fresh air volume; or, appropriately reduce the opening of the fresh air damper, and at the same time may need to increase the opening of the return air damper to keep the total air volume unchanged or adjust it as needed.

Therefore, the fresh air volume is determined by acquiring the wind speed and time information, so as to accurately and reasonably introduce fresh air according to the actual situation, thereby effectively improving the indoor air quality and creating a healthy indoor air environment for users.
