[0030] As shown in the first aspect, the embodiments of the present application provide a fresh air control method for controlling a fresh air air conditioner. The fresh air control method comprises S10-S40, and can achieve a good fresh air control effect and improve indoor air quality more quickly. Figure 1

[0031] The fresh air air conditioner comprises a fresh air module, and the fresh air module comprises a fresh air fan. When the fresh air fan is running, a pressure difference can be formed between the indoor and outdoor environments, and then outdoor fresh air can be sucked into the indoor environment. The type of the fresh air air conditioner can be determined according to actual needs, and air conditioners with a fresh air function such as wall-mounted air conditioners, cabinet air conditioners, window air conditioners, and the like can be used. The embodiments of the present application do not limit this.

[0032] S10: Determine whether a fresh air starting condition is met. Here, the fresh air starting condition can be determined according to actual needs, for example, indoor and outdoor temperature difference conditions, indoor and outdoor air quality conditions, and the like. The embodiments of the present application do not limit this.

[0033] S20: In response to determining that the fresh air starting condition is met, control the fresh air fan to start. When it is determined that the fresh air starting condition is met, the fresh air fan can be controlled to start, so as to suck outdoor fresh air into the indoor environment and then improve indoor air quality.

[0034] S30: According to the volume flow rate of the fresh air fan, the indoor space volume, the outdoor air quality, and the indoor air quality, predict an indoor air quality compliance time.

[0035] ​Here, the volume flow rate of the fresh air fan refers to the fresh air flow rate sucked in by the fresh air fan in a unit of time when the fresh air fan is running. The indoor space volume refers to the volume of the current indoor space, which can be manually input by the user or determined by measuring with a distance measuring sensor arranged on the indoor side of the fresh air conditioner. The outdoor air quality can be determined by real-time measurement with a sensor arranged on the outdoor side of the fresh air conditioner, or can be obtained by the fresh air conditioner from air quality information published by an air quality measurement unit through a communication network. The indoor air quality can be determined by real-time measurement with a sensor arranged on the indoor side of the fresh air conditioner.

[0036] According to the volume flow rate of the fresh air fan, the indoor space volume, the outdoor air quality and the indoor air quality, the time required for the indoor air quality to reach the preset air standard can be predicted based on an air quality standard reaching prediction model pre-set in the fresh air conditioner. The type of the air quality standard reaching prediction model can be determined according to actual needs, and types such as artificial neural network prediction models can be used, which are not limited by the embodiments of the present application.

[0037] S40: Adjusting the operation parameter of the fresh air fan according to the indoor air quality reaching time.

[0038] After predicting the indoor air quality reaching time, the operation parameter of the fresh air fan can be adjusted according to the indoor air quality reaching time to shorten the indoor air quality reaching time, so that the indoor air quality reaches the preset air standard quickly in a short time, thereby quickly improving the air quality of the indoor environment.

[0039] Compared with the related art, the fresh air control method provided by the embodiments of the present application can control the fresh air fan to start when the fresh air starting condition is met, and predict the indoor air quality reaching time according to the volume flow rate of the fresh air fan, the indoor space volume, the outdoor air quality and the indoor air quality, and then adjust the operation parameter of the fresh air fan according to the indoor air quality reaching time, so that the indoor air quality reaches the preset air standard quickly in a short time, thereby quickly improving the air quality of the indoor environment.

[0040] As shown in FIG. 4, Figure 2 In some embodiments, S40 can include S41-S44.

[0041] S41: Determining the reaching time interval in which the indoor air quality reaching time is located.

[0042] Here, a plurality of target time intervals successively and continuously distributed can be pre-set in the control system of the fresh air conditioner, and different preset acceleration amounts are set for each target time interval. The specific value of the preset acceleration amount can be determined according to actual needs, and can be set to zero or a non-zero value; when the preset acceleration amount is zero, the rotational speed of the fresh air fan can be controlled to remain unchanged by using the preset acceleration amount; when the preset acceleration amount is a non-zero value, the rotational speed of the fresh air fan can be gradually increased by using the preset acceleration amount to gradually shorten the indoor air quality target time. For example, the longer the indoor air quality target time, the greater the corresponding preset acceleration amount; conversely, the shorter the indoor air quality target time, the smaller the corresponding preset acceleration amount.

[0043] In some examples, three target time intervals successively and continuously distributed can be pre-set in the control system of the fresh air conditioner, i.e., a first target time interval greater than a first target time threshold, a second target time interval less than or equal to the first target time threshold and greater than a second target time threshold, and a third target time interval less than or equal to the second target time threshold. The first preset acceleration amount can be set for the first target time interval, the second preset acceleration amount can be set for the second target time interval, and the third preset acceleration amount can be set for the third target time interval, and the first preset acceleration amount, the second preset acceleration amount and the third preset acceleration amount decrease successively. For example, the third preset acceleration amount can be zero; for another example, the third preset acceleration amount can be a non-zero value. The specific values of the first target time threshold and the second target time threshold can be determined according to actual needs, which are not limited by the embodiments of the present application; for example, the first target time threshold can be 20-22 min, and the second target time threshold can be 10-12 min.

[0044] S42: in response to determining that the indoor air quality target time is located in the first target time interval, the rotational speed of the fresh air fan is accelerated by the first preset acceleration amount every preset time interval.

[0045] The preset time interval can be pre-set in the control system of the fresh air conditioner, and is used as the time interval between the two acceleration actions of the fresh air fan. The specific value of the preset time interval can be determined according to actual needs, which is not limited by the embodiments of the present application; for example, the preset time interval can be set to 8-12 min, and different values such as 8 min, 9 min, 10 min, 11 min or 12 min can be used.

[0046] When it is determined that the indoor air quality compliance time is located in the first compliance time interval, it can be determined that a very long time is needed to improve the indoor air quality to above the preset air standard if the current speed of the fresh air fan is used. At this time, the speed of the fresh air fan can be controlled to be accelerated by a first preset acceleration value which is relatively large every preset time interval; in other words, the speed of the fresh air fan can be first controlled to increase by the first preset acceleration value, and the fresh air fan can be controlled to run at the accelerated speed for the preset time interval, and then the speed of the fresh air fan can be controlled to increase by the first preset acceleration value again after the preset time interval is reached, so as to gradually shorten the indoor air quality compliance time, so that the indoor air quality can reach the preset air standard quickly in a relatively short time.

[0047] S43: In response to determining that the indoor air quality compliance time is located in the second compliance time interval, the speed of the fresh air fan is controlled to be accelerated by a second preset acceleration value every preset time interval. The first preset acceleration value is greater than the second preset acceleration value, and the second preset acceleration value is greater than zero.

[0048] When it is determined that the indoor air quality compliance time is located in the second compliance time interval, it can be determined that a relatively long time is needed to improve the indoor air quality to above the preset air standard if the current speed of the fresh air fan is used. At this time, the speed of the fresh air fan can be controlled to be accelerated by a second preset acceleration value which is relatively moderate every preset time interval; in other words, the speed of the fresh air fan can be first controlled to increase by the second preset acceleration value, and the fresh air fan can be controlled to run at the accelerated speed for the preset time interval, and then the speed of the fresh air fan can be controlled to increase by the second preset acceleration value again after the preset time interval is reached, so as to gradually shorten the indoor air quality compliance time, so that the indoor air quality can reach the preset air standard quickly in a relatively short time.

[0049] S44: In response to determining that the indoor air quality compliance time is located in the third compliance time interval, the speed of the fresh air fan is controlled to be accelerated by a third preset acceleration value every preset time interval.

[0050] The second preset acceleration is greater than the third preset acceleration, and the third preset acceleration is greater than or equal to zero. When the third preset acceleration is zero, the speed of the fresh air fan can be controlled to remain unchanged. When the third preset acceleration is greater than zero, the speed of the fresh air fan can be controlled to gradually increase every preset time interval. The specific values of the first preset acceleration, the second preset acceleration and the third preset acceleration can be determined according to actual needs, and the embodiments of the present application do not limit this. For example, the first preset acceleration can be set to 18-22 rpm, and different values such as 18 rpm, 19 rpm, 20 rpm, 21 rpm or 22 rpm can be used. For example, the second preset acceleration can be set to 8-12 rpm, and different values such as 8 rpm, 9 rpm, 10 rpm, 11 rpm or 12 rpm can be used. For example, the third preset acceleration can be set to 0-2 rpm, and different values such as 0, 1 rpm or 2 rpm can be used.

[0051] When it is determined that the indoor air quality compliance time is located in the third compliance time interval, it can be determined that if the fresh air fan is operated at the current speed, a relatively short time or a slightly longer time is needed to improve the indoor air quality to above the preset air standard. At this time, the speed of the fresh air fan can be controlled to accelerate by the third preset acceleration which is a small value or even zero every preset time interval. In other words, if only a relatively short time is needed to improve the indoor air quality to above the preset air standard, the third preset acceleration can be set to a value greater than zero, at this time, the speed of the fresh air fan can be first increased by the third preset acceleration, and the fresh air fan can be operated at the accelerated speed for a preset time interval, and then the speed of the fresh air fan can be controlled to increase by the third preset acceleration again after the preset time interval is reached. If a slightly longer time is needed to improve the indoor air quality to above the preset air standard, the third preset acceleration can be set to zero, at this time, the speed of the fresh air fan can be controlled to remain unchanged.

[0052] By setting S41-S44, the fresh air control method provided by the embodiments of the present application can control the speed of the fresh air fan to gradually accelerate to different degrees according to the compliance time interval in which the indoor air quality compliance time is located, so that the indoor air quality can quickly reach the preset air standard in a relatively short time, thereby quickly improving the air quality of the indoor environment.

[0053] As shown in FIG. 1, Figure 3 In some embodiments, S10 can include S11-S14.

[0054] S11: In response to the fresh air conditioner being in a cooling mode, determining whether the indoor air temperature is greater than the outdoor air temperature.

[0055] Here, the indoor air temperature can be measured in real time by a temperature sensor installed on the indoor side of the fresh air conditioner, while the outdoor air temperature can be measured in real time by a temperature sensor installed on the outdoor side of the fresh air conditioner. When the fresh air conditioner is in cooling mode, the obtained indoor and outdoor air temperatures can be compared to determine whether the intake of outdoor fresh air will cause fluctuations in the indoor air temperature.

[0056] S12: In response to determining that the indoor air temperature is greater than the outdoor air temperature, determine that the fresh air start-up conditions are met.

[0057] When the indoor air temperature is determined to be higher than the outdoor air temperature, it can be determined that the intake of outdoor fresh air will not cause fluctuations in the indoor air temperature. At this time, the indoor air temperature can be reduced by using the lower-temperature outdoor fresh air, thereby reducing the cooling capacity required for the fresh air air conditioner to operate. Therefore, it can be determined that the conditions for starting the fresh air system are met.

[0058] S13: In response to determining that the indoor air temperature is less than or equal to the outdoor air temperature, determine whether the outdoor air quality is better than the indoor air quality.

[0059] When the indoor air temperature is determined to be less than or equal to the outdoor air temperature, it can be confirmed that drawing in fresh outdoor air will cause fluctuations in the indoor air temperature, exacerbating the heat of the indoor environment. In this case, it can be further determined whether the outdoor air quality is superior to the indoor air quality, to ascertain whether outdoor air can be used to improve indoor air quality.

[0060] S14: In response to determining that the outdoor air quality is better than the indoor air quality, determine that the conditions for starting fresh air are met.

[0061] When it is determined that the outdoor air quality is better than the indoor air quality, the outdoor air can be used to improve the indoor air quality, so it can be determined that the conditions for starting fresh air are also met.

[0062] By setting S11 to S14, it is possible to accurately determine whether the conditions for starting fresh air are met, so that the fresh air fan can be started in a timely manner to meet the needs of fresh air intake as soon as possible.

[0063] like Figure 4 As shown, in some embodiments, after S20, the fresh air control method may include S51 to S53.

[0064] S51: Determine whether the indoor ambient brightness is greater than or equal to the preset brightness.

[0065] Here, the indoor ambient brightness can be measured in real time by a brightness sensor installed on the indoor side of the fresh air conditioner; the preset brightness can be pre-set in the control system of the fresh air conditioner to determine the activity status of indoor users.

[0066] S52: In response to determining that the indoor ambient brightness is greater than or equal to the preset brightness, the upper limit of the speed of the fresh air fan is set to the first upper limit of the speed.

[0067] S53: In response to determining that the indoor ambient brightness is less than a preset brightness, the upper limit of the speed of the fresh air fan is set to a second upper limit. Wherein, the first upper limit is greater than the second upper limit; for example, the first upper limit can be an integer multiple of the second upper limit, such as 2 times, 3 times, or other multiples.

[0068] When the indoor ambient brightness is greater than or equal to the preset brightness, it can be determined that the indoor user is currently awake and active. In this case, the upper limit of the fresh air fan speed can be set to a higher first speed limit, allowing the fresh air fan to operate at a higher speed to quickly meet the indoor user's fresh air needs. When the indoor ambient brightness is less than the preset brightness, it can be determined that the indoor user is currently asleep or resting. In this case, the upper limit of the fresh air fan speed can be set to a lower second speed limit, limiting the fresh air fan speed to a lower level to avoid generating excessive operating noise and thus avoid disturbing the indoor user's rest.

[0069] By setting S51 to S53, the activity status of indoor users can be determined based on the indoor ambient brightness. Then, the upper limit of the fresh air fan speed can be adjusted according to the activity status of indoor users. This allows the fresh air fan to run at a higher speed when the user is awake and at a lower speed when the user is resting, thus better meeting the user's needs in different activity states.

[0070] like Figure 5 As shown, in some embodiments, after S20, the fresh air control method may include S61 to S62.

[0071] S61: Determine whether the room is unoccupied and whether the duration of the unoccupied state is less than a preset time.

[0072] Here, a human detection sensor installed on the indoor side of the fresh air conditioner can determine whether the room is unoccupied and whether the duration of vacancy is less than a preset time. The type of human detection sensor can be determined according to actual needs, and can include, for example, a distance sensor, a pyroelectric sensor, or a camera; this embodiment does not limit this. The preset time can be pre-set in the control system of the fresh air conditioner, and the specific value of the preset time can be determined according to actual needs; this embodiment does not limit this. For example, the preset time can be set to 3 to 5 minutes, such as 3 minutes, 4 minutes, or 5 minutes.

[0073] S62: In response to determining that the indoor is empty and the duration of the indoor being empty is less than the preset time, controlling the fresh air fan to reduce to the lowest speed.

[0074] When it is determined that the indoor is empty and the duration of the indoor being empty is less than the preset time, it can be determined that the current indoor has been empty for a long time, at which time the speed of the fresh air fan can be controlled to reduce to the lower limit of the speed, so as to maintain the fresh air function and reduce the operation energy consumption of the fresh air function, and achieve a better energy saving effect.

[0075] In some embodiments, the fresh air module can include a humidifying mechanism and a dehumidifying mechanism, the humidifying mechanism being configured to humidify the fresh air sucked from the outdoor, and the dehumidifying mechanism being configured to dehumidify the fresh air sucked from the outdoor. As shown in FIG. 1, after S20, the fresh air control method can include S71-S73. Figure 6

[0076] S71: In response to determining that the indoor air humidity is less than the first preset humidity, controlling the humidifying mechanism to start.

[0077] S72: In response to determining that the indoor air humidity is greater than the second preset humidity, controlling the dehumidifying mechanism to start.

[0078] S73: In response to determining that the indoor air humidity is greater than or equal to the first preset humidity and less than or equal to the second preset humidity, controlling the humidifying mechanism and the dehumidifying mechanism to stop.

[0079] Wherein, the first preset humidity is less than the second preset humidity. The specific values of the first preset humidity and the second preset humidity can be determined according to actual needs, which are not limited by the embodiments of the present application; for example, the first preset humidity can be set to 35%-45%, and the second preset humidity can be set to 55%-65%.

[0080] In some examples, after S20, the fresh air control method can include S63.

[0081] S63: In response to determining that the indoor is not empty, controlling the fresh air fan to reduce to the lowest speed, and detecting the indoor air humidity, and then performing S71-S73.

[0082] By setting S61-S63 and S71-S73 at the same time, the humidity control can be automatically performed when the indoor is not empty, further improving the comfort of the indoor environment.
