S200, calculating the percentage a% of the difference between the particulate matter concentration and the particulate matter concentration threshold value in the particulate matter concentration threshold value; for example, the threshold particulate matter concentration may be 35-75 μ g/m3After the concentration of the PM2.5 is obtained, the difference between the concentration of the PM2.5 and the particulate matter concentration threshold is calculated, the ratio of the difference to the particulate matter concentration threshold is calculated, and the percentage a% is obtained through unit conversion.
S300, calculating the percentage b% of the difference between the bacteria concentration and the bacteria concentration threshold value in the bacteria concentration threshold value; for example, the threshold bacterial concentration may be 100-150CUF/m3After the concentration of the bacteria is obtained, the bacteria are calculatedAnd calculating the ratio of the difference to the bacterial concentration threshold value, and obtaining the percentage b% after unit conversion.
S400, controlling the opening degrees of the first valve body 121, the second valve body 91, the third valve body 92 and the fourth valve body 93 based on the calculation result; for example, when a is greater than 0 and b is less than or equal to 0, it is proved that the concentration of the particulate matter in the exhaust section is relatively high, and the concentration of the bacteria is normal, at this time, the first valve body 121 needs to be controlled to be closed to a small opening degree, the second valve body 91 and the fourth valve body 93 need to be opened to a certain opening degree, and the third valve body 92 needs to be closed, so that a part of air in the exhaust section flows back to the first air return section through the air return pipeline 9, and flows through the high-efficiency filtering section again for air filtering, and the purpose of reducing the concentration of the particulate matter; if a is less than or equal to 0 and b is greater than 0, the concentration of the particulate matters in the exhaust section is normal, and the concentration of the bacteria is higher, at this time, the first valve body 121 needs to be controlled to be closed to a small opening degree, the third valve body 92 and the fourth valve body 93 need to be opened to a certain opening degree, and the second valve body 91 needs to be closed, so that a part of air in the exhaust section flows back to the second backflow section through the return air pipeline 9, and flows through the sterilization section for sterilization, and the purpose of reducing the concentration of the bacteria in the exhaust air is achieved.
Through the control mode, the control method of the combined air conditioner can monitor the discharged air and adjust the air flow direction of the combined air conditioner based on the monitoring result, the purifying and sterilizing effects are guaranteed, and the discharged air is enabled to reach the standard.
In a preferred embodiment, taking the air quality detecting device 7 as a PM2.5 sensor and the bacteria detecting device 8 as a total number of colonies detector as an example, the step S400 further includes:
(1) when a is more than 0 and b is less than or equal to 0, the first valve body 121, the second valve body 91 and the fourth valve body 93 are controlled to be opened, the third valve body 92 is controlled to be closed, and the opening angles of the first valve body 121, the second valve body 91 and the fourth valve body 93 are controlled based on a percentage of a%. Specifically, when a is greater than 0 and b is less than or equal to 0, the opening angle of the first valve body 121 is controlled to be (100-a/k)1) % controlling the opening angles of the second valve body 91 and the fourth valve body 93 to be (a/k)1)％。
For example, particulate matterThe threshold concentration may be 75 μ g/m3The threshold bacterial concentration may be 150CUF/m3When a is more than 0 and b is less than or equal to 0, the concentration of PM2.5 in the air of the air outlet section at the moment is proved to exceed 75 mu g/m3The concentration of bacteria is less than 150CUF/m3Namely, the concentration of PM2.5 exceeds the standard, the concentration of bacteria is in a normal interval, and the filtering strength of the air flow needs to be increased so as to reduce the concentration of PM2.5 in the air. Therefore, the first valve element 121, the second valve element 91 and the fourth valve element 93 are controlled to be opened, the third valve element 92 is controlled to be closed, and a part of air in the exhaust section flows back to the first air return section through the air return pipeline 9 and flows through the high-efficiency filter assembly 4 again for secondary filtration.
At the opening angle, since the PM2.5 concentration exceeds the standard at this time, the opening angles of the first valve body 121, the second valve body 91, and the fourth valve body 93 can be controlled based on the percentage a%, and the percentage a% is in an inverse relationship with the opening angle of the first valve body 121 and in a direct relationship with the opening angles of the second valve body 91 and the fourth valve body 93. For example, assume k1Current PM2.5 concentration of 150 μ g/m ═ 103If a% (150-75)/75 × 100% (% 100), the opening angle of the first valve element 121 may be controlled to (100-100/10)% (90%), and the opening angles of the second valve element 91 and the fourth valve element 93 may be controlled to (100/10)% (10%).
(2) When a is less than or equal to 0 and b is more than 0, the first valve body 121, the third valve body 92 and the fourth valve body 93 are controlled to be opened, the second valve body 91 is controlled to be closed, and the opening angles of the first valve body 121, the third valve body 92 and the fourth valve body 93 are controlled based on the percentage b%. Specifically, when a is less than or equal to 0 and b is greater than 0, the opening angle of the first valve body 121 is controlled to be (100-b/k)2) % controlling the opening angles of the third valve body 92 and the fourth valve body 93 to (b/k)2)％。
For example, the threshold particulate matter concentration may be 75 μ g/m3The threshold bacterial concentration may be 150CUF/m3When a is less than or equal to 0 and b is more than 0, the concentration of PM2.5 in the air of the air outlet section is less than 75 mu g/m3The concentration of bacteria exceeds 150CUF/m3Namely, the concentration of PM2.5 is normal, the concentration of bacteria exceeds the standard, and the sterilization intensity of the air flow needs to be increased so as to reduce the number of bacteria in the air. Thus controllingThe first valve body 121, the third valve body 92 and the fourth valve body 93 are opened, the second valve body 91 is controlled to be closed, and a part of air in the air exhaust section flows back to the second air return section through the air return pipeline 9 and flows through the sterilization device 5 again for secondary sterilization.
At the opening angle, since the bacterial concentration exceeds the standard at this time, the opening angles of the first valve body 121, the third valve body 92 and the fourth valve body 93 can be controlled based on the percentage b%, and the percentage b% is in an inverse relationship with the opening angle of the first valve body 121 and in a direct relationship with the opening angles of the third valve body 92 and the fourth valve body 93. For example, assume k2Current bacterial concentration of 600CUF/m 103If b% ((600-.
(3) When a > 0 and b > 0, the first valve body 121, the second valve body 91, and the fourth valve body 93 are controlled to be opened, the third valve body 92 is controlled to be closed, and the opening angles of the first valve body 121, the second valve body 91, and the fourth valve body 93 are controlled based on the larger of the percentage a% and the percentage b%. Specifically, when a > 0 and b > 0, the opening angle of the first valve body 121 is controlled to be [100-max (a, b)/k3]% controlling the opening angle of the second valve body 91 and the fourth valve body 93 to [ max (a, b)/k%3]％。
For example, the threshold particulate matter concentration may be 75 μ g/m3The threshold bacterial concentration may be 150CUF/m3When a is more than 0 and b is more than 0, the concentration of PM2.5 in the air of the air outlet section at the moment is proved to exceed 75 mu g/m3The concentration of bacteria exceeds 150CUF/m3Namely, the concentration of PM2.5 and the concentration of bacteria exceed the standard, the filtration intensity and the sterilization intensity of the air flow need to be increased simultaneously, so as to reduce the concentration of PM2.5 and the number of bacteria in the air. Therefore, the first valve body 121, the second valve body 91 and the fourth valve body 93 are controlled to be opened, the third valve body 92 is controlled to be closed, so that a part of air in the air exhaust section flows back to the first air return section through the air return pipeline 9, and flows through the high-efficiency filtering assembly 4 and the sterilizing device 5 in sequence again to perform secondary filtering and secondary sterilization.
In the opening angle, because the concentration of PM2.5 and the concentration of bacteria both exceed the standard at this time, the opening angles of the first valve body 121, the second valve body 91 and the fourth valve body 93 can be controlled based on the larger of the percentage a% and the percentage b% to ensure that the index which exceeds the standard more seriously is effectively suppressed, and the larger of the percentage a% and the percentage b% has an inverse relation with the opening angle of the first valve body 121 and has a direct relation with the opening angle of the third valve body 92 and the opening angle of the fourth valve body 93. For example, assume k3Current PM2.5 concentration of 150 μ g/m ═ 103When the current bacteria concentration is 600CUF/m3, a% (150-75)/75 × 100% ((100-75)/75 × 100% ((600-)))/150 × 100% (300%), and a < b%, the opening angles of the first valve element 121, the second valve element 91, and the fourth valve element 93 may be controlled based on the percentage b%, where the opening angle of the first valve element 121 is controlled to be (100-300/10)% (% 70%), and the opening angles of the second valve element 91 and the fourth valve element 93 are controlled to be (300/10)% (% 30%).
(4) When a is less than or equal to 0 and b is less than or equal to 0, the first valve body 121 is controlled to be fully opened, and the second valve body 91, the third valve body 92 and the fourth valve body 93 are controlled to be closed. Specifically, when a is equal to or less than 0 and b is equal to or less than 0, the opening degree of the first valve body 121 is controlled to be 100%, and the opening degrees of the second valve body 91, the third valve body 92 and the fourth valve body 93 are controlled to be 0%.
As can be understood by those skilled in the art, when a is less than or equal to 0 and b is less than or equal to 0, the concentration of PM2.5 in the air of the air outlet section at the moment is proved to be less than 75 mu g/m3The concentration of bacteria is less than 150CUF/m3The concentration of PM2.5 and the concentration of bacteria are normal, and at this time, special control is not required, and only the current valve body opening/closing state is required to be maintained, and the first valve body 121 is controlled to be opened, and the second valve body 91, the third valve body 92 and the fourth valve body 93 are controlled to be closed.
By controlling the opening of each valve body based on the percentages of a% and b%, the control method can carry out targeted adjustment based on the current air exhaust condition, so that the purification and sterilization capacity of the combined air conditioner is matched with the exhaust air condition, and the stable quality of the exhaust air is ensured.
