Detailed Description
The embodiment of the invention solves the technical problem of poor rationality of a ventilation strategy of a fresh air system in the prior art by providing the fresh air system control method, the fresh air system and the air conditioner.
In order to better understand the technical scheme of the present invention, the following detailed description will refer to the accompanying drawings and specific embodiments.
First, the term "and/or" appearing herein is merely an association relationship describing associated objects, meaning that there may be three relationships, e.g., a and/or B, may represent: a exists alone, A and B exist together, and B exists alone. In addition, the character "/" herein generally indicates that the front and rear associated objects are an "or" relationship.
As shown in fig. 1, the fresh air system of the embodiment includes a fresh air fan, a plurality of air outlet pipelines and a plurality of air return pipelines, wherein the plurality of air outlet pipelines are respectively connected with an air outlet of the fresh air fan and a plurality of partitions in one-to-one correspondence, and the plurality of air return pipelines are respectively connected with an air return inlet of the fresh air fan and the plurality of partitions in one-to-one correspondence. In fig. 1, the air blown out by the fresh air machine is blown to a plurality of subareas through a plurality of air outlet pipelines, and the air in the subareas is returned to the fresh air machine through a plurality of air return pipelines and blown out of the subareas, so that ventilation is realized.
As shown in fig. 2, the fresh air system control method of the present embodiment includes:
step S1, acquiring an air pollution index of an environment where each partition is located in a plurality of partitions;
and S2, controlling ventilation control parameters of the fresh air system according to the air pollution index corresponding to each partition. The ventilation control parameters of the fresh air system determine the ventilation effect of the fresh air system on the subareas.
Therefore, in this embodiment, the ventilation control parameters of the fresh air system are controlled according to the air pollution indexes corresponding to each partition, and since the air pollution indexes corresponding to each partition represent the current air quality situation of the partition, the method is equivalent to determining the ventilation control strategy of the fresh air system according to the current air quality situation of the partition, and the ventilation strategy of the fresh air system is adapted to the current air quality situation of the partition, so that the rationality of the ventilation strategy of the fresh air system is improved.
The present embodiment provides a plurality of ventilation control parameters and a plurality of strategies for controlling the ventilation control parameters according to the air pollution index, which will be described below.
In this embodiment, the ventilation control parameters of the fresh air system may include the air outlet intensity of the fresh air blower, and step S2 may include: and controlling the air outlet intensity of the fresh air machine according to a plurality of air pollution indexes corresponding to the plurality of partitions. It can be understood that the higher the air outlet intensity of the fresh air fan is, the larger the air quantity and the air speed of each subarea are, and the better the subarea ventilation effect is; the larger the air pollution indexes corresponding to the plurality of subareas, the higher the air outlet intensity of the fresh air blower should be in principle, so that the plurality of subareas can be ventilated rapidly.
The controlling the air outlet intensity of the fresh air machine may have a plurality of types, for example, controlling the air outlet intensity of the fresh air machine according to the sum, the square sum, the weight sum, and the like of a plurality of air pollution indexes corresponding to a plurality of partitions, and in the preferred step S2 in this embodiment, controlling the air outlet intensity of the fresh air machine according to a plurality of air pollution indexes corresponding to a plurality of partitions includes: and controlling the air outlet intensity of the fresh air machine according to the sum of a plurality of air pollution indexes corresponding to the plurality of partitions.
There are various methods for controlling the air-out strength according to the sum of the air pollution indexes, for example, the air-out strength of the fresh air machine is proportional to the sum of the air pollution indexes corresponding to the partitions. In a preferred step S2 in this embodiment, controlling the air outlet intensity of the fresh air machine includes: determining a first index interval in which the sum of a plurality of air pollution indexes corresponding to the plurality of partitions is located; and controlling the air outlet intensity of the fresh air machine to be the target intensity corresponding to the first index interval, wherein the larger the index average value in the first index interval is, the larger the corresponding target intensity is.
Specifically, the first index intervals and the target intensities corresponding to the first index intervals may be preset, for example, the target intensity corresponding to 0<S-API less than or equal to 150 is the first intensity (representing low wind), the target intensity corresponding to 150< S-API less than or equal to 300 is the second intensity (representing stroke), the target intensity corresponding to 300< S-API less than or equal to 400 is the third intensity (representing second high wind), the target intensity corresponding to 400< S-API less than or equal to 500 is the fourth intensity (representing high wind), the target intensity corresponding to 500< S-API less than or equal to 600 is the fifth intensity (representing high wind), the target intensity corresponding to 600< S-API is the sixth intensity (representing strong wind), and S-API is the sum of the air pollution indexes corresponding to the partitions. Therefore, when the air quality of the multiple subareas is worse, the air outlet intensity of the fresh air machine is higher, the multiple subareas can be quickly ventilated, and the air quality of the multiple subareas is quickly improved; when the air quality of the multiple subareas is good, the air outlet intensity of the fresh air machine is weaker, so that the power consumption of the fresh air machine is reduced.
In this embodiment, the ventilation control parameters of the fresh air system may further include fresh air control parameters corresponding to each partition, and step S2 includes: and controlling fresh air control parameters corresponding to each partition according to the air pollution index corresponding to the partition. The fresh air control parameters corresponding to each partition can be of different types, and are described below.
As shown in fig. 1, in the fresh air system of this embodiment, each air outlet pipeline may be provided with an air valve, and at this time, the fresh air control parameter corresponding to each partition may include an opening of the air valve corresponding to the partition. It can be understood that the larger the opening of the air valve corresponding to a certain partition is, the more the air quantity obtained by the partition is, and the better the effect of improving the air quality of the partition is.
As shown in fig. 1, in the fresh air system of this embodiment, each return air pipeline may be provided with a fan, and at this time, the fresh air control parameter corresponding to each partition may include a gear of the fan corresponding to the partition. It can be understood that the higher the gear of the fan corresponding to a certain partition, the faster the air in the partition is discharged, and the higher the efficiency of improving the air quality of the partition is.
When the air valve is arranged in each air outlet pipeline and the fan is arranged in each air return pipeline, the fresh air control parameter corresponding to each partition can comprise the opening degree of the air valve corresponding to the partition and the gear of the fan.
Whether the fresh air control parameter corresponding to each partition only includes the opening of the air valve corresponding to the partition, only includes the gear of the fan corresponding to the partition, or includes both the opening of the air valve corresponding to the partition and the gear of the fan corresponding to the partition, in step S2, the fresh air control parameter corresponding to each partition is controlled according to the air pollution index corresponding to the partition, which may be: the fresh air control parameter corresponding to each partition is controlled to be in direct proportion to the air pollution index corresponding to the partition, and the fresh air control parameter can also be: determining a second index interval in which an air pollution index corresponding to each partition is positioned; and controlling the fresh air control parameter corresponding to each partition to be a target control parameter corresponding to a second index interval, wherein the larger the index average value in the second index interval is, the larger the corresponding target control parameter is. When the fresh air control parameter corresponding to each partition only comprises the opening of the air valve corresponding to the partition, the opening of the air valve corresponding to each partition can be controlled to be in direct proportion to the air pollution index corresponding to the partition, or a second index interval in which the air pollution index corresponding to each partition is located is determined, and the opening of the air valve corresponding to each partition is controlled to be a target opening corresponding to the second index interval (namely, the target control parameter is the target opening); when the fresh air control parameter corresponding to each partition only comprises the gear of the fan corresponding to the partition, the gear of the fan corresponding to each partition can be controlled to be in direct proportion to the air pollution index corresponding to the partition, or a second index interval in which the air pollution index corresponding to each partition is located is determined, and the gear of the fan corresponding to each partition is controlled to be a target gear corresponding to the second index interval (namely, the target control parameter is the target gear); when the fresh air control parameter corresponding to each partition includes the opening of the air valve corresponding to the partition and the gear of the fan, the opening of the air valve corresponding to each partition and the gear of the fan can be controlled to be in direct proportion to the air pollution index corresponding to the partition, or a second index interval where the air pollution index corresponding to each partition is located is determined, and the opening of the air valve corresponding to each partition and the gear of the fan are controlled to be the target opening and the target gear corresponding to the second index interval (namely, the target control parameter includes the target opening and the target gear).
For the second index section, a plurality of second index sections and target openings and/or target gear positions corresponding to the second index sections may be preset, for example, the target opening corresponding to 50< API less than or equal to 100 is 30 °, the target gear position is a stop gear, the target opening corresponding to 100< API less than or equal to 150 is 45 °, the target gear position is a stop gear, the target opening corresponding to 150< API less than or equal to 200 is 60 °, the target gear position is a stop gear, the target opening corresponding to 200< API less than or equal to 300 is 90 ° (full open), the target gear position is a low gear, the target opening corresponding to 300< API is 90 ° (full open), the target gear position is a high gear, and the API is an air pollution index corresponding to a single partition.
In fact, when the fresh air control parameter corresponding to each partition comprises the opening of the air valve corresponding to the partition and the gear of the fan, if the air pollution index corresponding to a certain partition is smaller, the air valve corresponding to the partition does not reach full opening yet, so that the opening of the air valve can be increased along with the increase of the air pollution index, the ventilation effect is improved only by controlling the opening of the air valve, and the fan does not need to be opened, so that the power consumption is reduced; however, when the air pollution index corresponding to a certain partition is large, the corresponding air valve may be fully opened at this time, the ventilation effect cannot be improved by continuously increasing the opening of the air valve, and the fan needs to be opened to improve the ventilation efficiency. Therefore, in the embodiment, when the fresh air control parameter corresponding to each partition includes the opening of the air valve and the gear of the fan corresponding to the partition, in the step S2, the fresh air control parameter corresponding to the partition is preferably controlled according to the air pollution index corresponding to each partition, including:
when the air pollution index corresponding to the partition is lower than a preset pollution index threshold value, an air valve corresponding to the partition is opened, and a fan is closed; when the air pollution index corresponding to the partition is higher than a preset pollution index threshold value, the air valve corresponding to the partition is fully opened, and the fan is opened. In the above example, the preset pollution index threshold is 200. Like this when the blast gate that the subregion corresponds is fully opened and can't continue to improve the effect of taking a breath through controlling the blast gate aperture, can take away the inside air of subregion that air quality is relatively poor through the fan, the inside negative pressure that forms of subregion is favorable to introducing this subregion with new trend, reduces new fan air-out pressure simultaneously, increases new fan return air pressure, improves new fan ventilation efficiency.
In addition, when a fan is arranged in each return air pipeline, the fresh air system control method of the embodiment further comprises the following steps: monitoring the running state of a fresh air system; if the fresh air system is in a fault state, the return air pipeline is controlled to be communicated with the external environment and the corresponding partition, and the fan is controlled to operate so as to pump air of the external environment to the corresponding partition through the fan. Therefore, when the fresh air system fails, external air can be directly pumped into the subareas through the fan, and ventilation is completed when the fresh air system fails.
As shown in fig. 3, the embodiment of the invention further provides a fresh air system, which comprises a fresh air fan, a controller, a plurality of detectors, a plurality of air outlet pipelines and a plurality of air return pipelines; the air outlet pipelines are respectively connected with the air outlet of the fresh air machine and the partitions in a one-to-one correspondence manner, the air return pipelines are respectively connected with the air return inlet of the fresh air machine and the partitions in a one-to-one correspondence manner, and the detectors are respectively arranged in the partitions in a one-to-one correspondence manner; the plurality of detectors are in communication connection with the controller, and each detector is used for detecting the air pollution index of the environment where the corresponding partition is located; the controller is used for acquiring an air pollution index corresponding to each of the plurality of partitions; and controlling the ventilation control parameters of the fresh air system according to the air pollution index corresponding to each partition.
According to the fresh air system, the ventilation control parameters of the fresh air system are controlled according to the air pollution indexes corresponding to each partition, and the air pollution indexes corresponding to each partition represent the current air quality of the partition, so that the ventilation control strategy of the fresh air system is determined according to the current air quality of the partition, the fresh air system adapts to the ventilation strategy of the partition and the current air quality of the partition, and the rationality of the ventilation strategy of the fresh air system is improved.
As shown in fig. 4, 5 and 6, the return air pipeline of the present embodiment includes a first pipeline and a second pipeline, where the first pipeline connects the corresponding partition and the return air inlet; the second pipeline connects the corresponding partition with the air return port as shown in fig. 5, and/or the corresponding partition with the external environment as shown in fig. 6; a fan is arranged in the second pipeline.
The first pipeline and the second pipeline can be communicated all the time, or can be switched between communication and sealing, and the communication and sealing of the first pipeline and the second pipeline can be realized through valves. When the first pipeline is conducted and the second pipeline is closed, the fan does not work, as shown in fig. 4; when the second pipeline is communicated with the corresponding subareas and the return air inlet and the first pipeline is closed, the fan rotates positively to pump air of the corresponding subareas to the return air inlet, as shown in fig. 5, the controller can control the gear of the fan according to the air pollution index corresponding to each subarea, and ventilation efficiency is improved. When the second pipeline is conducted with the corresponding subarea and the external environment, the first pipeline is also closed, the fan is reversed, and external air is pumped to the corresponding subarea, as shown in fig. 6, so that when the fresh air system fails, the external air can be directly pumped into the subarea through the fan, and ventilation is completed when the fresh air system fails.
In addition, as shown in fig. 4, 5 and 6, the fresh air system of the embodiment further includes an air outlet box and an air return box, and an air valve is arranged in each air outlet pipeline; the air outlet is connected with the air outlet through the air outlet box, and the air return pipelines are connected with the air return opening through the air return box.
