To address the problems noted in the background, according to an aspect of an embodiment of the present application, an embodiment of an indoor static pressure adjusting method is provided.
Alternatively, in the embodiment of the present application, the above-described indoor static pressure adjustment method may be applied to a hardware environment formed by the fan 101 and the server 103 as shown in fig. 1. As shown in fig. 1, the server 103 is connected to the fan 101 through a network, which may be used to control the fan's speed, on or off, and a database 105 may be provided on or separate from the server for providing data storage services to the server 103, the network including but not limited to: a wide area network, a metropolitan area network, or a local area network.
The method for adjusting the indoor static pressure in the embodiment of the application can be executed by the server 103 and is used for automatically and accurately controlling the indoor static pressure to reach the set static pressure.
An indoor static pressure adjusting method provided in the embodiments of the present application will be described in detail below with reference to specific embodiments, as shown in fig. 2, the specific steps are as follows:
step 201: and acquiring the actual static pressure, the preset highest static pressure and the preset lowest static pressure in the chamber.
Wherein the highest static pressure and the lowest static pressure are obtained according to the set static pressure.
In the embodiment of the application, the service acquires the actual static pressure P _ real in a room, sets the static pressure P _ set and the static pressure tolerance P _ tor, and determines the set static pressure as positive pressure or negative pressure according to an actual applicable scene.
The server takes the sum of the set static pressure and the static pressure tolerance as the highest static pressure P _ set + P _ tor, and the difference between the set static pressure and the static pressure tolerance as the lowest static pressure P _ set-P _ tor.
Step 202: and if the actual static pressure is between the lowest static pressure and the highest static pressure within the preset time, adjusting the actual static pressure by adopting a single-type fan matched with the type of the set static pressure until the actual static pressure is equal to the set static pressure.
Wherein, the single-type fan is a blower or an exhaust fan.
In the embodiment of the application, if P _ set-P _ tor < = P _ real < = P _ set + P _ tor in the preset time period t2 indicates that the actual static pressure is close to the set static pressure, only a blower or an exhaust fan is used for adjusting the actual static pressure at this time, so as to achieve the purpose of accurate adjustment. Specifically, the use of a blower or an exhaust fan is associated with the type of the set static pressure, which includes positive pressure or negative pressure.
In this application, if it is long to predetermine interior actual static pressure of duration and be located between minimum static pressure and the highest static pressure, it has been close to the settlement static pressure to show actual static pressure, then adopts single type fan to adjust actual static pressure, realizes accurate regulation static pressure. The application can realize quick, accurate and automatic adjustment of the indoor actual static pressure.
As an optional implementation manner, if the actual static pressure is smaller than the lowest static pressure or larger than the highest static pressure within the preset time period, which indicates that the actual static pressure is far away from the set static pressure, the two fans with opposite wind direction outputs are used for adjusting the actual static pressure, so that the static pressure is quickly adjusted.
In the embodiment of the application, if P _ real < P _ set-P _ tor or P _ real > P _ set + P _ tor within the preset time period t2 indicates that the actual static pressure is far away from the set static pressure, the blower and the exhaust fan need to be adopted to adjust the actual static pressure at the same time, so that the purpose of quick adjustment is achieved.
As an alternative implementation, if the actual static pressure is less than the minimum static pressure within the preset time period, the adjustment of the actual static pressure by the blower and the exhaust fan includes two examples:
in one embodiment, if the actual static pressures are all smaller than the minimum static pressure within the preset time period, which indicates that the current actual static pressure is too small, the blower is adjusted to supply air at the highest rotation speed and the exhaust fan exhausts air at the lowest rotation speed, so that the actual static pressure is increased at the highest efficiency.
In another embodiment, if the actual static pressures are all larger than the highest static pressure within the preset time period, which indicates that the current actual static pressure is too large, the exhaust fan is adjusted to exhaust air at the highest rotating speed, and the air feeder is adjusted to supply air at the lowest rotating speed, so that the actual static pressure is reduced at the highest efficiency.
As an alternative embodiment, after the actual static pressure is adjusted by the blower and the exhaust fan, the method further comprises: if the actual static pressure is still smaller than the lowest static pressure or larger than the highest static pressure, determining that the fan setting is wrong, wherein the fan setting comprises the highest rotating speed and the lowest rotating speed of the fan or the type selection of a motor of the fan; and sending an alarm to a preset terminal, wherein the alarm is used for indicating that the setting of the fan needs to be adjusted.
After the actual static pressure is adjusted by adopting the air feeder and the exhaust fan, if the actual static pressure is still less than the minimum static pressure, the highest rotating speed of the air feeder, the minimum rotating speed of the exhaust fan or the type selection of the motor of the fan is determined, and if errors are set, an alarm is sent to a preset terminal to prompt the recalibration of the highest rotating speed of the air feeder, the minimum rotating speed of the exhaust fan or the purchase of the motor again.
After the actual static pressure is adjusted by the air feeder and the exhaust fan, if the actual static pressure is still larger than the highest static pressure, the highest rotating speed of the exhaust fan, the lowest rotating speed of the air feeder or the type selection of the motor of the fan is determined, if errors are set, an alarm is sent to a preset terminal to prompt the recalibration of the highest rotating speed of the exhaust fan, the lowest rotating speed of the air feeder or the purchase of the motor again.
Specifically, if the indoor pressure P _ real < P _ set-P _ tor or P _ real > P _ set + P _ tor is detected within the preset time period t2, it indicates that the actual static pressure is farther from the set static pressure.
For the interval P _ real < P _ set-P _ tor, the blower is at the highest rotating speed and the exhaust fan is at the lowest rotating speed, after a period of time, the actual static pressure still meets the condition that P _ real < P _ set-P _ tor, which indicates that the highest rotating speed of the blower or the lowest rotating speed of the exhaust fan has problems or the type selection of the motor has problems, and the rotating speed needs to be corrected and adjusted again or the motor needs to be purchased.
For the interval P _ real > P _ set + P _ tor, if the exhaust fan is at the highest rotating speed at the moment, the blower is at the lowest rotating speed, and after a period of time, the actual static pressure still meets the requirement of the P _ real > P _ set + P _ tor, which indicates that the highest rotating speed of the exhaust fan or the lowest rotating speed of the blower is in trouble, or the motor is in trouble in type selection, and the rotating speed needs to be corrected and adjusted again or the motor needs to be purchased.
As an alternative embodiment, if the actual static pressure is between the lowest static pressure and the highest static pressure within the preset time period, adjusting the actual static pressure using a single type of fan that matches the type of the set static pressure until the actual static pressure is equal to the set static pressure includes: if the actual static pressure is between the lowest static pressure and the highest static pressure within the preset time, determining that the fan to be adjusted is in a first category according to the type of the set static pressure, wherein the type of the static pressure is positive pressure or negative pressure; and adjusting the first type of fan to operate at a limit rotation speed according to the relation between the actual static pressure and the set static pressure until the actual static pressure reaches the set static pressure, wherein the limit rotation speed is the highest rotation speed or the lowest rotation speed.
If within the preset time period t2, P _ set-P _ tor < = P _ real < = P _ set + P _ tor, determining whether the set static pressure is positive pressure or negative pressure, if so, determining that the fan to be adjusted is a blower, and if so, determining that the fan to be adjusted is an exhaust fan.
And adjusting the first type of fan to operate at a limit rotation speed according to the relation between the actual static pressure and the set static pressure until the actual static pressure reaches the set static pressure, wherein the limit rotation speed is the highest rotation speed or the lowest rotation speed. At this point, the second category of fans maintains their original rotational speed.
After adjusting the first category of fans to operate at the limit speed, the method further comprises: and if the actual static pressure does not reach the set static pressure, controlling the first type of fan to keep running at the limit rotating speed, and adjusting the rotating speed of the second type of fan until the actual static pressure reaches the set static pressure, wherein the air outlet direction of the second type of fan is opposite to the air outlet direction of the first type of fan, namely, the air supply fan and the air outlet fan, and the rotating speed adjusting direction of the second type of fan is opposite to the rotating speed adjusting direction of the first type of fan, namely, the rotating speed is increased and the rotating speed is reduced.
If the actual static pressure is between the lowest static pressure and the highest static pressure within the preset time, the method for adjusting the actual static pressure by adopting the single-type fan matched with the type of the set static pressure comprises two embodiments:
in one embodiment, if the static pressure is set to a positive pressure, the fan to be adjusted is determined to be a blower.
1. If P _ set-P _ tor < = P _ real < = P _ set indicates that the actual static pressure is positive pressure and is low, the blower is adjusted to operate at the highest rotation speed, and therefore the indoor static pressure is increased. If the actual static pressure does not reach the set static pressure, the blower is controlled to keep running at the highest rotating speed, and the rotating speed of the exhaust fan is adjusted to be reduced so as to increase the pressure of the actual static pressure.
2. If P _ set < = P _ real < = P _ set + P _ tor, the actual static pressure is positive pressure and is high, the blower is adjusted to operate at the lowest rotation speed. At this point, the exhaust fan maintains its original rotational speed. If the actual static pressure does not reach the set static pressure, the blower is controlled to operate at the lowest rotating speed, and the rotating speed of the exhaust fan is adjusted to be increased so as to reduce the pressure of the actual static pressure.
When the actual static pressure is positive pressure, the blower is firstly adjusted to operate at the limit rotating speed, and if the set static pressure cannot be met, the rotating speed of the exhaust fan is adjusted. In this process, only one type of fan is kept to be adjusted at a time, thereby achieving accurate adjustment.
In another embodiment, if the static pressure is set to be negative pressure, the fan to be adjusted is determined to be an exhaust fan.
1. If P _ set-P _ tor < = P _ real < = P _ set indicates that the actual static pressure is negative pressure and is low, the exhaust fan is adjusted to operate at the lowest rotating speed, and therefore the indoor static pressure is increased. And if the actual static pressure does not reach the set static pressure, controlling the exhaust fan to keep running at the lowest rotating speed, and increasing the rotating speed of the adjusting air blower to increase the pressure of the actual static pressure.
2. If P _ set < = P _ real < = P _ set + P _ tor indicates that the actual static pressure is negative and is higher, the exhaust fan is adjusted to operate at the highest rotation speed. At this time, the blower maintains its original rotational speed. If the actual static pressure does not reach the set static pressure, the exhaust fan is controlled to keep running at the highest rotating speed, and the rotating speed of the adjusting air blower is reduced to reduce the pressure of the actual static pressure.
When the actual static pressure is negative pressure, the exhaust fan is adjusted to operate at the limit rotating speed, and if the set static pressure cannot be met, the rotating speed of the air feeder is adjusted. In this process, only one type of fan is kept to be adjusted at a time, thereby achieving accurate adjustment.
In the adjusting process, as long as the exhaust fan is not at the lowest rotating speed or the highest rotating speed in the interval, the air feeder is not allowed to be adjusted, and the current rotating speed needs to be maintained; similarly, as long as the blower starts to operate, the exhaust fan needs to maintain the current rotating speed. This is for when actual static pressure is close to the setting static pressure, two fans adjust overshoot and undulant big simultaneously, can't be close to the setting static pressure for a long time.
As an alternative embodiment, before adjusting the actual static pressure with the fan, the method further comprises: preferentially starting the fan of the first category after starting up according to the set static pressure of positive pressure or negative pressure, and starting the fan of the second category after the target duration; after the actual static pressure reaches the set static pressure, the method further comprises: and after the shutdown, the fans of the second category are preferentially closed, and the fans of the first category are closed after the target duration.
In order to maintain the indoor positive pressure environment, the blower control is mainly used, and the exhaust fan control is used for controlling the indoor static state. After the machine is started, the air feeder is started according to the lowest rotation speed of the air feeder, after the machine is started for t1 time, the exhaust fan is started according to the lowest rotation speed, after the air feeders and the exhaust fans are all started, the rotation speed of the air feeders and the exhaust fans is regulated according to a PID algorithm, and the rotation speed of the air feeders and the exhaust fans is not lower than the respective lowest rotation speed in the regulation process. After the machine is shut down, the exhaust fan is preferentially closed, and after the machine is closed for t1 time, the blower is closed.
If the indoor negative pressure environment is to be maintained, the exhaust fan control is mainly used, and the air blower control is used for controlling indoor static. After the machine is started, the exhaust fan is started according to the lowest rotation speed of the exhaust fan preferentially, the air feeder is started according to the lowest rotation speed after the exhaust fan is started for t1 time, the rotation speed of the air feeder and the exhaust fan is regulated according to a PID algorithm after the air feeder and the exhaust fan are all started, and the rotation speed of the air feeder and the exhaust fan is not lower than the respective lowest rotation speed in the regulation process. After the machine is shut down, the blower is preferentially shut off, and after the machine is shut off for t1 time, the exhaust fan is shut off.
The specific flow of the scheme is as follows:
first, if P _ real < P _ set-P _ tor or P _ real > P _ set + P _ tor, it means that the actual static pressure is farther from the set static pressure.
1. For the interval P _ real < P _ set-P _ tor, the blower is at the highest rotating speed and the exhaust fan is at the lowest rotating speed, after a period of time, the actual static pressure still meets the requirement of the P _ real < P _ set-P _ tor, which indicates that the highest rotating speed of the blower or the lowest rotating speed of the exhaust fan has problems or the motor has problems in selection, and the rotating speed needs to be corrected and adjusted again or the motor needs to be purchased.
2. For the interval P _ real > P _ set + P _ tor, if the exhaust fan is at the highest rotating speed at the moment, the blower is at the lowest rotating speed, and after a period of time, the actual static pressure still meets the requirement of the P _ real > P _ set + P _ tor, which indicates that the highest rotating speed of the exhaust fan or the lowest rotating speed of the blower is in trouble, or the motor is in trouble in type selection, and the rotating speed needs to be corrected and adjusted again or the motor needs to be purchased.
If P _ set-P _ tor < = P _ real < = P _ set + P _ tor, it means that the actual static pressure approaches the set static pressure.
1. And if the static pressure is set to be negative pressure, determining that the fan to be adjusted is a blower.
(1) If P _ set-P _ tor < = P _ real < = P _ set indicates that the actual static pressure is positive pressure and is low, the blower is adjusted to operate at the highest rotation speed, and therefore the indoor static pressure is increased. If the actual static pressure does not reach the set static pressure, the blower is controlled to keep running at the highest rotating speed, and the rotating speed of the exhaust fan is adjusted to be reduced so as to increase the pressure of the actual static pressure.
(2) If P _ set < = P _ real < = P _ set + P _ tor, the actual static pressure is positive pressure and is high, the blower is adjusted to operate at the lowest rotation speed. At this point, the exhaust fan maintains its original rotational speed. If the actual static pressure does not reach the set static pressure, the blower is controlled to operate at the lowest rotating speed, and the rotating speed of the exhaust fan is adjusted to be increased so as to reduce the pressure of the actual static pressure.
When the actual static pressure is positive pressure, the blower is firstly adjusted to operate at the limit rotating speed, and if the set static pressure cannot be met, the rotating speed of the exhaust fan is adjusted. In this process, only one type of fan is kept to be adjusted at a time, thereby achieving accurate adjustment.
2. And if the static pressure is set to be negative pressure, determining that the fan to be adjusted is an exhaust fan.
(1) If P _ set-P _ tor < = P _ real < = P _ set indicates that the actual static pressure is negative pressure and is low, the exhaust fan is adjusted to operate at the lowest rotating speed, and therefore the indoor static pressure is increased. And if the actual static pressure does not reach the set static pressure, controlling the exhaust fan to keep running at the lowest rotating speed, and increasing the rotating speed of the adjusting air blower to increase the pressure of the actual static pressure.

At this time, the blower maintains its original rotational speed. If the actual static pressure does not reach the set static pressure, the exhaust fan is controlled to keep running at the highest rotating speed, and the rotating speed of the adjusting air blower is reduced to reduce the pressure of the actual static pressure.
