Because the fresh air system is mostly preset with a fixed opening value, when the indoor air quality reaches the opening value of the fresh air system, the fresh air system is opened to process the indoor air. However, the indoor environment is not constant, and the fresh air system is controlled to be opened by using a fixed opening value, so that the fresh air system cannot adapt to the indoor environment under various conditions, and the condition that the fresh air system is opened too early or too late is easily caused. Therefore, the embodiment of the application provides a control method of a fresh air system, which can be applied to the fresh air system.
A detailed description will be given below, with reference to a specific embodiment, of a method for controlling a fresh air system provided in an embodiment of the present application, as shown in fig. 1, the specific steps are as follows:
s101, acquiring indoor current environmental parameters.
In the embodiment of the present application, the current environmental parameter is used to characterize the current indoor air quality condition, and may be a parameter directly affecting the air quality, such as: carbon dioxide concentration in air, PM2.5 value, formaldehyde concentration, or the like; parameters that indirectly affect the air quality may also be present, such as: the temperature or the number of people in the room can indirectly influence the air quality because the volatilization conditions of the gases such as formaldehyde and the like in the room are different at different temperatures, and similarly, the number of people can indirectly influence the air quality because different numbers of people exist in the room and the generation conditions of the gases such as carbon dioxide and the like in the room are different.
And S102, determining a current target adjusting value of the indoor fresh air system according to the current environmental parameters.
In this embodiment of the application, the current target adjustment value may be an opening critical value of the fresh air system for a certain environmental parameter, for example, when the current target adjustment value is an opening critical value of the fresh air system for a concentration of a pollutant (such as carbon dioxide or formaldehyde), and when the concentration of the pollutant in the room is lower than the current target adjustment value, the concentration of the pollutant in the room is a low concentration, and it is not necessary to purify and ventilate the indoor air. The current target adjustment value can be flexibly set according to the current indoor environment parameters.
S103, controlling the fresh air system according to the current target adjusting value.
In the embodiment of the application, the control on the fresh air system can be opening control and closing control on the fresh air system, and after the current target adjusting value is determined, the opening and closing of the fresh air system can be controlled according to the current target adjusting value.
In the embodiment of the application, firstly, indoor current environmental parameters are obtained; then, determining a current target adjusting value of the indoor fresh air system according to the current environmental parameters; and finally, controlling the fresh air system according to the current target adjusting value. That is, through this application, can be according to the nimble current target adjustment value that sets up of indoor current environmental parameter, then control new trend system according to current target adjustment value to the realization is according to the nimble new trend system that opens of current indoor environment, makes opening of new trend system adapt to current indoor environment, avoids new trend system to open too early or too late.
In another embodiment of the present application, the S102 may include the following steps:
step one, calculating an environment change parameter according to a current environment parameter obtained within a period of time;
and step two, calculating a current target adjusting value according to the environment change parameters.
In an embodiment of the present application, the environmental change parameter is used to characterize an environmental change condition, such as a rate of change of a contaminant, within the room. The calculation cycle may be preset, and the environment change parameter may be calculated according to the current environment parameter obtained within a period of time every one calculation cycle. After the environmental change parameter is obtained, the current target adjustment value can be calculated according to the environmental change parameter.
In the embodiment of the application, the environment change parameter can be calculated according to the current environment parameter obtained in a period of time; then, a current target adjustment value is calculated according to the environment change parameter. Therefore, the current target adjusting value can be flexibly set according to the change condition of the indoor environment, and the set current target adjusting value is more consistent with the current environment condition.
In another embodiment of the present application, the second step may include the following steps:
s201, acquiring an initial starting value and unit change parameters of the fresh air system.
In the embodiment of the present application, the initial opening value refers to a fixed opening value preset in the fresh air system, the fixed opening value is generally an opening critical value for the concentration of the indoor pollutants, and when the fresh air system is controlled by using the initial opening value, the fresh air system is opened when the concentration of the indoor pollutants reaches the initial opening value. The unit change parameter refers to a value of a contaminant change rate referred to when setting an initial opening value. The initial starting value and unit change parameters of the fresh air system can be directly acquired from the pre-stored information of the fresh air system.
S202, judging whether the change rate of the pollutants is greater than the unit change parameter.
In an embodiment of the present application, the environmental change parameter comprises a rate of change of a contaminant. By determining whether the rate of change of the contaminant is greater than the unit change parameter, it is determined whether the condition of the air in the room is aggravated as compared to setting the initial turn-on value. For example, a unit change parameter of 10g per hour and a contaminant change rate of 20g per hour indicates that the indoor air condition has worsened compared to the initial opening value. At the moment, if the fresh air system is controlled according to the initial opening value, the fresh air system is easily opened to a period of time after the fresh air system is opened, the concentration of indoor pollutants exceeds a preset air standard value, and the indoor air is caused to be below the standard air quality.
S203, when the pollutant change rate is larger than the unit change parameter, acquiring the outdoor pollutant concentration.
In the embodiment of the present application, the outdoor pollutant concentration may be an actual concentration value of the pollutant in the outdoor air collected by the collecting device; or after the fresh air system purifies the collected outdoor air, the concentration value of pollutants in the purified air is detected.
When the contaminant change rate is greater than the unit change parameter, which indicates that the indoor air condition has been aggravated compared to when the initial opening value is set, at this time, in order to subsequently calculate the current target adjustment value, the outdoor contaminant concentration needs to be obtained.
S204, determining the current target adjusting value based on the initial opening value, the unit change parameter, the pollutant change rate and the outdoor pollutant concentration.
In the embodiment of the present application, the current target adjustment value may be calculated based on the following formula:
wherein: p is the current target regulating value; p1 is the initial opening value; p2 is outdoor contaminant concentration; u is the rate of change of the contaminant; u1 is a unit variation parameter, where P1 is greater than P2.
The relation between the current target adjusting value and the pollutant change rate when the fresh air system is started is provided in the formula (I), and the formula is used for determining the current target adjusting value, so that the timeliness of starting the fresh air system can be met.
In the embodiment of the application, because the current target adjusting value is flexibly set according to the pollutant change rate, and can be known by the formula (I), the larger the pollutant change rate is, the smaller the current target adjusting value is, therefore, when the indoor air quality aggravates deterioration, the current target adjusting value can be automatically set to a smaller value according to the formula (I), so that the fresh air system can be started in advance, namely, the air in the space where the fresh air system is located is processed in advance, and the condition that the air quality deteriorates to be below the standard air quality is reduced.
In another embodiment of the present application, the second step may include the following steps:
step one, when the pollutant change rate is smaller than or equal to the unit change parameter, the initial opening value is determined as a current target adjusting value.
In this application embodiment, when pollutant change rate is less than or equal to unit change parameter, confirm that indoor air condition does not aggravate when setting up initial opening value relatively and worsen, at this moment, confirm that initial opening value is current target adjustment value, promptly, can control new trend system according to initial opening value this moment, need not to change, through this scheme, when confirming pollutant change rate is less than or equal to unit change parameter, can directly confirm initial opening value and be current target adjustment value, need not to calculate, save computational resource.
In yet another embodiment of the present application, the method may further comprise the steps of:
s301, determining a difference value between the current environment parameter and the current target adjusting value;
s302, determining a target time based on the difference and the environment change parameter, wherein the differential result of the target time and the environment change parameter is the difference;
and S303, controlling the indoor fresh air system to be started by using the target time.
In this embodiment of the present application, a difference between a current environmental parameter and a current target adjustment value may be determined, and based on the difference and an environmental change parameter, a target time required to reach the current target adjustment value according to an indoor air quality change condition may be determined, where a relationship between the difference, the environmental change parameter, and the target time is: the environmental change parameter d target time ═ difference. After the target time is determined, the indoor fresh air system can be started after the target time is reached. According to the scheme, the current environmental parameters can be detected without detecting for a period of time after the target time is determined, the fresh air system is directly controlled to be started after the target time is reached, and the control process is simpler and more efficient.
In another embodiment of the present application, the S103 may include the following steps:
step one, when the current environmental parameter is larger than or equal to the current target adjusting value, controlling the indoor fresh air system to be started.
And step two, when the current environmental parameter is smaller than the current target adjusting value, judging whether the environmental change parameter is smaller than or equal to a preset threshold value.
And step three, controlling the indoor fresh air system to be closed when the environment change parameter is less than or equal to a preset threshold value.
In the embodiment of the application, when the current environmental parameter is greater than or equal to the current target adjusting value, the fresh air system in the control room is started; when the current environmental parameter is smaller than the current target adjusting value, whether the environmental change parameter is smaller than or equal to a preset threshold value or not is judged, preferably, the preset threshold value is set to be zero, and when the environmental change parameter is smaller than or equal to the preset threshold value, the fresh air system in the control room is closed. Through this scheme, can be according to opening and closing of pollutant concentration and pollutant rate of change automatic control new trend system, need not artificial control, saved the manpower.
In yet another embodiment of the present application, the method may further comprise the steps of:
s401, obtaining the indoor space volume and the outdoor pollutant concentration.
In the embodiment of the application, the volume of the indoor space can be detected by the detection device or input by a user, and the concentration of the outdoor pollutant can be an actual concentration value of the pollutant in the outdoor air collected by the collection device; or after the fresh air system purifies the collected outdoor air, the concentration value of pollutants in the purified air is detected.
S402, determining a target air volume based on the current target adjusting value, the indoor space volume, the outdoor pollutant concentration and the environment change parameter.
In the embodiment of the present application, the target air volume may be calculated based on the following formula:
wherein: a is target air volume; u is the rate of change of the contaminant; v is the volume of the indoor space; t is preset time; p2 is outdoor contaminant concentration; p is the current target regulating value; τ is the enhancement factor. The formula (II) provides the relation between the fresh air opening value, the fresh air volume when the air conditioner is opened and the indoor air quality change rate. The target air volume obtained by the relational expression calculation controls the fresh air system, and the current environmental parameters can be ensured to return to the value below the current target regulation value within the preset time T.
And S403, controlling the fresh air system to supply air according to the target air volume.
In the embodiment of the application, when the fresh air system is started, the fresh air system is controlled to supply air according to the calculated target air volume, so that the current environmental parameters are reduced to be below the current target adjusting value within the preset time T after the fresh air system is started.
In the embodiment of the application, the target air volume is calculated through a formula (II), and the relation between the fresh air opening value, the fresh air volume when the air volume is opened and the indoor air quality change rate is provided. When the fresh air system is started, the target air volume obtained through the relational expression calculation controls the fresh air system, and the current environmental parameters can be enabled to return to the value below the current target regulation value within the preset time T, so that the indoor air quality is rapidly improved, and the rapid full-house fresh air is realized.
In yet another embodiment of the present application, the method may further comprise the steps of:
step one, after the fresh air system is started, acquiring first time for starting the fresh air system and second time for reducing the current environmental parameter to the current target regulation value.
And step two, determining the time difference between the first time and the second time as a reference time.
And step three, adjusting the target air volume based on the difference value between the reference time and the preset time.
In the embodiment of the application, after the target air volume is determined according to the formula (II), the fresh air system supplies air according to the target air volume, and in an ideal state, the current environmental parameters can return to the value below the current target regulation value within the preset time T. However, due to the influence of the fan power of the fresh air system and the like, the actual processing time is longer than the preset time T. In this case, the target air volume needs to be corrected.
After the fresh air system is started, acquiring first time for starting the fresh air system and second time for reducing the current environmental parameter to a current target regulation value, then determining the time difference between the first time and the second time as reference time, and finally comparing the reference time with the preset time, wherein when the reference time is less than or equal to the preset time, the air supply according to the target air volume can ensure that the current environmental parameter returns to P within the preset time and is below the current target regulation value, and at the moment, the target air volume can be properly reduced according to the difference between the reference time and the preset time; when the reference time is longer than the preset time, the current environmental parameter can not be enabled to return to the value P which is below the current target adjusting value in the preset time according to the target air volume air supply; at this time, the target air volume can be properly adjusted according to the difference between the reference time and the preset time. Wherein the difference is proportional to the adjustment.
In the embodiment of the application, the target air volume can be adjusted by comparing the preset time and returning the current environmental parameters to the actual time below the current target adjusting value when the fresh air system sends air according to the target air volume, so that the target air volume is more consistent with the indoor air quality change condition. The problem that the target air volume is too large and wastes resources is avoided, or the target air volume is too small and the indoor air treatment is not efficient enough is avoided.
