Example 1
Referring to fig. 1, fig. 1 is a flow chart of a nozzle dirty blocking recognition method according to the present embodiment. The nozzle dirty blockage recognition method comprises the following steps:
S101, controlling the air conditioning unit to start, and entering a dirty blocking recognition mode after the air conditioning unit stably operates.
In the embodiment, the method can automatically control the starting of the air conditioning unit and wait for the automatic operation t1 (t 1 is more than or equal to 9min and less than or equal to 12 min) of the air conditioning unit (the time of the unit starting and stopping the platform and the time required by the maximum frequency of operation are about 9min, and 0-3 min is added on the basis to ensure that the air conditioning unit stably operates).
For example, after the air conditioning unit is controlled to start, the air conditioning unit needs to be waited for 9 to 12 minutes to ensure the stable operation of the air conditioning unit.
In theory, the air conditioning unit can reach a stable operation state in 9 minutes of operation, because the air conditioning unit can reach the maximum operation frequency in 9 minutes, and the maximum frequency is unchanged in the absence of a condition, so that the stable operation can be realized in theory. However, this method reserves a time of 3 minutes, and the purpose is to wish to exclude unstable factors through the 3 minutes and perform stable operation detection, thereby ensuring stable operation of the air conditioning unit.
In this embodiment, stable operation of the air conditioning unit means that the operating frequency of the air conditioning unit remains substantially unchanged.
S102, recording a first high-pressure parameter value or a first exhaust temperature value of the air conditioning unit.
In the embodiment, after the air conditioning unit stably operates, the method records an initial first high-voltage parameter value Pd1 of the air conditioning unit; while an initial first exhaust gas temperature value Th1 may alternatively be recorded.
In this embodiment, the high-pressure parameter Pd of the air conditioning unit may be detected by the high-pressure sensor 502 of the air conditioning unit; the discharge temperature Th can be detected by the discharge bulb 503 of the air conditioning unit.
In this embodiment, the step of recording the first high-pressure parameter value or the first exhaust gas temperature value of the air conditioning unit occurs after the air conditioning unit is stably operated. It will be appreciated that from this step, all steps are performed after the air conditioning unit is operating steadily.
S103, controlling each nozzle to be independently opened in turn, and recording a second high-pressure parameter value or a second exhaust temperature value of the air conditioning unit when each nozzle is independently opened.
S104, determining whether the nozzle is blocked according to the second high-pressure parameter value or the second exhaust temperature value and the first high-pressure parameter value or the first exhaust temperature value.
In this embodiment, the method may perform a spray test on the first nozzle, record a second high-pressure parameter value or a second exhaust temperature value of the nozzle, and then determine whether there is a dirty blockage on the nozzle based on the second high-pressure parameter value or the second exhaust temperature value; after that, the method can also perform the filth blockage recognition on the second nozzle and the third nozzle, and the filth blockage can be controlled and recognized in turn.
S105, outputting a dirty blockage prompt message matched with the nozzle if the nozzle is dirty blocked.
In this embodiment, the method may perform the blocking prompt on the blocking nozzle by means of display, sound, etc., so that both the machine itself and the related person can know the blocking condition of the nozzle, thereby facilitating the subsequent cleaning operation.
In this embodiment, the execution subject of the method may be a computing device such as a computer or a server, which is not limited in this embodiment.
In this embodiment, the execution body of the method may be an intelligent device such as a smart phone or a tablet computer, which is not limited in this embodiment.
Therefore, by implementing the nozzle dirty blocking identification method described in the embodiment, the air conditioning unit can be started preferentially, so that the air conditioning unit can perform nozzle dirty blocking identification when running stably; at the moment, the high-pressure parameter or the exhaust temperature of the air conditioning unit is recorded, so that the obtained parameter value can be ensured to be stable and reliable, and the recognition and judgment of the subsequent nozzle filth blockage are facilitated; then, the method carries out spray control on each nozzle in turn, and automatically records the high-pressure parameter or the exhaust temperature when each nozzle carries out spray, so that the method can confirm whether the nozzle is dirty or not through calculation of the high-pressure parameter difference value or the exhaust temperature difference value, and further realize the real-time automatic nozzle dirty and blockage identification effect; finally, the method can output the nozzle dirty blocking prompt information when the dirty blocking nozzle exists, so that the water pump can press and rinse the nozzle, thereby ensuring the cleaning of the nozzle and being beneficial to improving the use efficiency of the air conditioning unit.
Example 2
Referring to fig. 2, fig. 2 is a flow chart of a nozzle dirty blocking recognition method according to the present embodiment. The nozzle dirty blockage recognition method comprises the following steps:
s201, controlling the air conditioning unit to start, and entering a dirty blocking recognition mode after the air conditioning unit stably operates.
As an optional implementation manner, the method for controlling the air conditioning unit to start and entering the filth blockage recognition mode after the air conditioning unit stably operates includes:
controlling the starting of an air conditioning unit;
and when the air conditioning unit operates to the maximum frequency, and after the air conditioning unit is controlled to wait for a preset stable operation time period, entering a dirty blockage recognition mode.
In the embodiment, the method can automatically control the starting of the air conditioning unit and wait for the automatic operation t1 (t 1 is more than or equal to 9min and less than or equal to 12 min) of the air conditioning unit (the time of the unit starting and stopping the platform and the time required by the maximum frequency of operation are about 9min, and 0-3 min is added on the basis to ensure that the air conditioning unit stably operates).
In this embodiment, the duration of waiting for the air conditioning unit to operate to the maximum frequency is about 9 minutes.
In this embodiment, the steady operation time is 0 to 3 minutes.
In this embodiment, stable operation of the air conditioning unit means that the operating frequency of the air conditioning unit remains substantially unchanged.
S202, recording a first high-pressure parameter value or a first exhaust temperature value of the air conditioning unit.
In the embodiment, after the air conditioning unit stably operates, the method records an initial first high-voltage parameter value Pd1 of the air conditioning unit; while an initial first exhaust gas temperature value Th1 may alternatively be recorded.
In this embodiment, the high-pressure parameter Pd of the air conditioning unit may be detected by the high-pressure sensor 502 of the air conditioning unit; the discharge temperature Th can be detected by the discharge bulb 503 of the air conditioning unit.
S203, controlling each nozzle to be independently opened in turn, and recording a second high-pressure parameter value or a second exhaust temperature value of the air conditioning unit when each nozzle is independently opened.
S204, determining whether the nozzle is blocked according to the second high-pressure parameter value or the second exhaust temperature value and the first high-pressure parameter value or the first exhaust temperature value.
As an alternative embodiment, the step of determining whether the nozzle is dirty or not according to the second high pressure parameter value or the second exhaust gas temperature value and the first high pressure parameter value or the first exhaust gas temperature value includes:
calculating a difference value between the first high-pressure parameter value and the second high-pressure parameter value to obtain a first difference value, or calculating a difference value between the first exhaust temperature value and the second exhaust temperature value to obtain a first difference value;
If the first difference value is smaller than a first preset visceral blockage threshold value, determining that the visceral blockage exists in the nozzle;
if the first difference value is greater than or equal to a first preset dirty blockage threshold value, determining that the nozzle is free of dirty blockage.
Referring to fig. 5, fig. 5 is a schematic structural diagram of a spraying device according to the present embodiment; referring to fig. 6, fig. 6 is a schematic circuit diagram of a control module in a spraying device according to the present embodiment. Details of the subsequent embodiments are described based on the explanation and application of fig. 5 and 6.
In this embodiment, fig. 5 shows a spray device capable of identifying nozzle clogging. Wherein, the water pump 401 pumps the water into the spraying module, and then the control module controls the electromagnetic valve to start the nozzle to spray the condenser 501. In addition, the shower device has not only the water pump 401, the solenoid valve and the nozzle connected to the solenoid valve, but also a high-pressure sensor 502, and the high-pressure sensor 502 may be replaced with a temperature sensor. The high pressure sensor 502 and the temperature sensor can acquire high pressure parameters and temperature parameters, thereby facilitating the recognition of the nozzle filth blockage situation.
In this embodiment, the spraying device in fig. 5 is further refined in fig. 6, where the electromagnetic valve is paired with an indicator light, the electronic valve is used for controlling spraying, the indicator light is used for indicating abnormal spraying, and the buzzer 408 is used for indicating abnormal spraying module. Wherein, the first indicator light 406, the first electromagnetic valve 402 and the first nozzle 404 are matched; the second indicator light 407, the second electromagnetic valve 403 and the second nozzle 405 are matched.
In this embodiment, the method can avoid spraying the second nozzle 405 by opening the first solenoid valve 402 and simultaneously closing the second solenoid valve 403 by the control module shown in fig. 5 and 6. At this time, the unit condenser 501 is sprayed through the first nozzle 404, after a certain time t2 (1 min is less than or equal to t2 is less than or equal to 3min,1min is used for indicating theoretical stable spraying time, 3min is used for indicating actual stable spraying time), the air conditioning unit records the high pressure Pd2, determines the dirty blockage, determines whether the pressure difference meets Δp=pd 1-Pd2 is more than or equal to Ps1 (0.03 Mpa is less than or equal to Ps1 is less than or equal to 0.06 Mpa) (determined according to sensor precision and experimental data), and after the air conditioning unit detects the determination, transmits a signal to a control module of the spraying device for control.
In this embodiment, a pressure difference satisfying ΔP=pd1-pd2.gtoreq.Ps1 (0.03 MPa.ltoreq.Ps1.ltoreq.0.06 MPa) means no fouling condition, and vice versa.
In this embodiment, the control module is used to open the first electromagnetic valve 402, close the second electromagnetic valve 403, avoid the second nozzle 405 from spraying, spray the unit condenser 501 through the first nozzle 404, after a certain time t2 (1 min is less than or equal to t2 is less than or equal to 3min,1min is used to represent the theoretical stable spraying time, 3min is used to represent the actual stable spraying time), record the exhaust temperature Th2 of the air conditioning unit, and perform the dirty and blockage judgment, judge whether the temperature difference satisfies Δth=th1-Th 2 is less than or equal to Ts1 (0.5 ℃ is less than or equal to Ts1 is less than or equal to 1.5 ℃) (determined according to the sensor precision and experimental data), and after the detection and judgment of the air conditioning unit, transmit the signal to the control module of the spraying device for control.
In this example, a temperature difference satisfying ΔTh=Tt1-Tt2.gtoreq.Ts1 (0.5deg.C.ltoreq.Ts1.ltoreq.1.5deg.C) means no fouling condition, and conversely means a fouling condition.
As an alternative embodiment, if all the nozzles are not dirty, the dirty identifying mode is exited, the air conditioning unit continues to operate normally, and step S207 is performed.
S205, outputting a dirty blockage prompt message matched with the nozzle if the nozzle is dirty blocked.
As an optional implementation manner, outputting the dirty blockage prompt information matched with the nozzle includes:
and turning on an indicator lamp corresponding to the nozzle.
In the embodiment, when the calculated pressure difference and the calculated temperature difference are judged to not meet the pressure difference requirement or the temperature difference requirement, the indication lamp corresponding to the electromagnetic valve is controlled to be turned on; otherwise, no processing is performed.
In this embodiment, since each judgment is separate. Therefore, after each judgment is completed, the method can close the electromagnetic valve and open the next electromagnetic valve, and judge each nozzle by controlling one until all the electromagnetic valves are judged one by one.
S206, determining the dirty nozzle according to the dirty prompting information, flushing the dirty nozzle, and executing step S207 after flushing is finished.
In this embodiment, if the nozzle is dirty, the method may flush the dirty nozzle by increasing the water pressure.
In this embodiment, if all the nozzles Δp meet the requirement, the comprehensive judgment stage (i.e., the subsequent step) is entered.
In this embodiment, step S205 may turn on the water pump 401, turn off the second electromagnetic valve 403, avoid the second nozzle 405 spraying, and turn on the first electromagnetic valve 402 to flush the first nozzle 404 by t3 (10S is less than or equal to t3 is less than or equal to 20S,10S is used for indicating that the cleaning can be theoretically performed, and 20S is used for ensuring that the cleaning is performed). After the flushing is finished, the electromagnetic valve is closed, the next flushing is carried out, and after all flushing is finished one by one, the comprehensive judgment stage is carried out.
S207, controlling all the nozzles to be opened, and recording a third high-pressure parameter value or a third exhaust temperature value of the air conditioning unit when all the nozzles are opened.

if the second difference value is greater than or equal to a second preset visceral blockage threshold value, determining that the visceral blockage identification result is that the visceral blockage does not occur.
In this embodiment, the method may turn on all the solenoid valves to spray t2 time (1 min is less than or equal to t2 is less than or equal to 3 min) to the condenser 501, record this high pressure Pd3, and perform dirty blockage judgment, whether the pressure difference satisfies Δp=pd3—pd1 is more than or equal to Ps2 (0.08 Mpa is less than or equal to Ps2 is less than or equal to 0.15 Mpa) (according to whether the spraying has the lowest function setting and experimental test determination).
In the embodiment, if the result is met, the nozzle dirty blockage judgment is exited, all the indicator lamps are closed, and the spraying device and the unit operate according to normal control; if the fault is not satisfied, the spraying device reports a fault, the buzzer 408 is controlled to be started through the spraying control module to perform buzzing alarm prompt, then the spraying device stops spraying, and the air conditioning unit operates according to normal control (another alarm prompt is that the fault alarm can be a method model prompt of displaying a fault code through the internal machine line controller).
In this embodiment, the method may turn on all the solenoid valves to spray t2 time (1 min is less than or equal to t2 is less than or equal to 3 min) to the condenser 501, record the exhaust temperature Th3, and perform dirty blockage judgment, whether the temperature difference satisfies Δth=th1-Th 3 is more than or equal to Ts2 (2 ℃ is less than or equal to Ts2 is less than or equal to 4 ℃) (according to whether the spraying has the lowest function setting and experimental test determination).
In the embodiment, if the result is met, the nozzle dirty blockage judgment is exited, all the indicator lamps are closed, and the spraying device and the unit operate according to normal control; if the fault is not satisfied, the spraying device reports a fault, the buzzer 408 is controlled to be started through the spraying control module to perform buzzing alarm prompt, then the spraying device stops spraying, and the air conditioning unit operates according to normal control (another alarm prompt is that the fault alarm can be a method model prompt of displaying a fault code through the internal machine line controller).
In the present embodiment, when the difference ΔP between the integrated high-pressure parameter value and the initial high-pressure parameter value is greater than Ps2 (0.08 MPa.ltoreq.S2.ltoreq.0.15 MPa); or when the difference DeltaT between the comprehensive exhaust temperature value and the initial exhaust temperature value is larger than Ts2 (the temperature is more than or equal to 2 ℃ and less than or equal to Ts2 and less than or equal to 4 ℃), the nozzle is considered to be spraying normally.
When the nozzle sprays, the high-pressure parameter or the exhaust temperature in the air conditioning unit is changed. In general, the variation of the high-pressure parameter is not very small, and similarly, the variation of the exhaust temperature is not very small. Therefore, the method sets a comparison threshold value, and determines whether the variation amplitude of the high-pressure parameter or the variation amplitude of the exhaust temperature is too small according to the threshold value, so that whether the spraying is abnormal or not is conveniently determined.
It will be appreciated that when the pressure differential is small or the temperature differential is small, it is generally the case that the nozzle is not operating properly, which in turn may be considered to be due to fouling of the nozzle. Therefore, by the method, whether the nozzle is blocked or not can be determined.
