Description
Technical Field
The invention relates to the field of air conditioners, in particular to a full water protection control method for an air conditioning unit, a storage medium, a processor and the air conditioning unit.
Background
Air conditioning unit can produce the comdenstion water in the refrigeration process, and is all direct to get rid of outdoors to most units, but to the single integral unit that uses at indoor, can't be convenient get rid of water in the use. Unless a drain pipe is added and directly connected, the use characteristic of the mobile machine and the like integrated machine set is that the mobile machine and the like integrated machine set can be conveniently moved, and the addition of the drain pipe is obviously not practical. Therefore, a water-fetching motor is generally added on the base plate to splash the condensed water onto the condenser, so that the problem of the condensed water can be solved, the latent heat value of the splashed water is increased after the splashed water contacts the condenser, the heat of the refrigerant is absorbed, and the refrigeration effect is further improved.
However, based on different use environments, the volume of the water receiving disc of the mobile machine is limited, the situation that condensed water is too much or even overflows in practical use can occur, at the moment, the water level switch floater of the unit floats upwards to act, the unit reports water full protection, then the compressor stops running, and the unit stops working. In order to eliminate the fault condition, the most adopted control method in the industry at present is to open a drain hole of a water receiving tray at the bottom, reduce the water level of condensed water to be below a water full warning line, float a water level switch floats downwards, the water full protection fault is eliminated, and a compressor is started to operate again. Although the problem of water full protection can be solved by the control, if the environmental humidity of the unit is high and a large amount of condensed water is generated, manual reset is frequently needed, the operation is troublesome and the user experience is influenced.
In the prior art, there is a first water-full protection control method: when the closing time of the water level collecting switch is more than the set time, the operation of the water pumping motor is stopped; and meanwhile, the unit stops running after the collected closing time of the water level switch and the running time of the water pumping motor exceed the set time. The water level control device is used for controlling the water level, but the water level control device is used for avoiding the water level protection and further starting the water pumping motor in the whole process, and meanwhile, the on-off of the water pumping motor is realized by depending on the action of a water level switch, so that the water level protection cannot be realized in the true sense.
In the prior art, there is a second water-full protection control method: the water collecting device adopts the following technical scheme that the full water protection is reported after the water collecting tray at the bottom is full of water, the compressor stops running at the moment, but the water fetching motor and the outdoor fan motor continuously run, and meanwhile, the outdoor fan is converted into a high wind level to continuously run, so that the volatilization of water is accelerated. And when the water level of the water receiving tray is lower than the warning water level, the compressor normally operates in a state before the air conditioner recovers. Although manual reset is avoided, the scheme can cause that the unit can reset and the compressor operates as soon as the water level is lower than the warning water level; then, the condensate water generated in the running process quickly leads to water full protection, so that the air conditioner is started and stopped frequently, and the user experience is also influenced. In addition, the rotating speed of the water fetching motor is not changed, the water evaporation of the outdoor fan at a high rotating speed cannot be met, the water level is lowered slowly in practice, and the water fetching effect is poor.
According to the two water-full protection control methods, the water pumping motor is started to reduce the water level when the water level of the collecting water pan is higher, but the water-full situation still occurs in actual use, and the protection control logic after the water-full situation is inevitably considered.
The above prior art solutions all have different degrees of one-sidedness. The technical scheme who has adopted needs artifical manual water collector water to be got rid of, and above-mentioned two kinds of schemes then inevitable make the unit can frequently get into and open and stop, greatly influence user experience. Therefore, the existing reset mode needs to be changed, so that the automatic reset can be realized without entering the frequent start-stop.

To further illustrate the technical solution of the present invention, the following specific examples are provided with reference to fig. 1 to 3.
As shown in fig. 1, in the prior art, after an air conditioner unit enters water full protection, two modes are adopted for dewatering, a water pumping motor and an outdoor fan stop running or run simultaneously, and when the water level of a water receiving tray is lower than a warning water level, a compressor resumes running.
Example 1
In the embodiment, in order to solve the above problem, a water full protection control method for an air conditioning unit is provided, as shown in fig. 2,
the air conditioning unit is provided with a water receiving tray for collecting condensed water, a water beating flywheel for beating the condensed water in the water receiving tray to the condenser and a water beating motor for providing power for the flywheel, and when the water level of the water receiving tray is more than or equal to the warning water level, the air conditioning unit is triggered to be full of water for protection and is controlled as follows:
stopping the compressor;
increasing the rotating speed of the water fetching motor;
the method comprises the steps of collecting the water level of a water receiving tray and the draft of a water beating flywheel in real time, and determining the reset time of a compressor based on the water level of the water receiving tray and the draft of the water beating flywheel.
Because the water receiving tray water level and the draft of the flywheel of fetching water can be reduced gradually in the dewatering process of the motor of fetching water, the reset time of the compressor can be determined by judging the water receiving tray water level and the water level of the flywheel of fetching water.
As a preferred mode of the present embodiment, the acquiring the water level of the water pan and the draft of the water beating flywheel in real time, and determining the compressor reset time based on the water level of the water pan and the draft of the water beating flywheel includes:
judging whether the water level of the water receiving tray is smaller than a warning water level or not;
and if the water level of the water receiving tray is smaller than the warning water level, determining the resetting time of the compressor according to a judgment result of whether the draft of the water beating flywheel is lower than the preset draft and/or whether the draft reduction rate of the water beating flywheel is greater than the preset draft reduction rate.
Preferably, the preset draft is (0.3-0.5) h, wherein h is the draft of the water fetching flywheel when the water receiving tray is at the warning water level.
The water level when the compressor resets is the water level that resets, the water level that resets is lower than the warning water level.
In the dewatering process of the dewatering flywheel, along with the reduction of the draft, the load of the dewatering motor is gradually reduced, and the dewatering speed of the dewatering motor is gradually increased, so that the draft reduction rate (the difference between the draft when the water is fully protected and the real-time draft is divided by the time) is increased, and the reset water level of the water pan (the water level of the water pan when the compressor is recovered to run) can be pre-judged through the draft and the draft reduction rate so as to determine the reset time of the compressor. Specifically, there may be three prediction methods:
firstly, when the water level of the water pan is smaller than the warning water level, judging according to whether the draft of the water-fetching flywheel is lower than a preset draft or not, namely, the time from the beginning of water removal of the water pan to the moment that the draft of the water-fetching flywheel is smaller than (0.3-0.5) h when the water is fully protected is the time for starting the compressor;
secondly, when the water level of the water pan is lower than the warning water level, judging according to whether the reduction rate of the water fetching flywheel is higher than a preset reduction rate; and starting from the water full protection, and taking time when the reduction rate is greater than the preset reduction rate as the compressor reset time.
Thirdly, when the draft of the water fetching flywheel and the reduction rate of the water fetching flywheel simultaneously satisfy the first and second conditions, the time taken for the water full protection to simultaneously satisfy the conditions is the compressor reset time.
In order to shorten the standby time of the compressor, the standby time can be shortened by increasing the rotating speed of the water fetching motor. Specifically, the increasing of the rotation speed of the water beating motor comprises the following steps: judging whether the difference value of the rotating speed of the current water beating motor compared with the preset maximum rotating speed of the water beating motor is smaller than a preset difference value or not; if the difference value is smaller than the preset difference value, the rotating speed of the water fetching motor is kept unchanged; and if the difference value is larger than or equal to the preset difference value, increasing the rotating speed of the water fetching motor.
Preferably, the rotating speed of the current water fetching motor is V, the maximum rotating speed Vmax of the water fetching motor is preset, the difference value of the rotating speed of the current water fetching motor and the maximum rotating speed is recorded as delta V, the delta V is Vmax-V, and the delta V is larger than or equal to (0-10%) Vmax.
Optionally, the water fetching motor is a direct current motor, and the rotation speed of the water fetching motor is increased by changing the voltage of the water fetching motor, namely, the input voltage of the water fetching motor is increased, so that the rotation speed of the water fetching motor is increased.
In order to further accelerate the water removal of the water receiving tray, when the water level of the water receiving tray is larger than or equal to the warning water level, the step of triggering the air conditioning unit to be full of water and protecting further comprises the step of increasing the rotating speed of an outdoor fan. When the water collector water level is greater than or equal to the warning water level, trigger the full water protection of air conditioning unit and still include the rotational speed that risees outdoor fan, include: the increasing of the rotating speed of the outdoor fan specifically comprises the following steps: judging whether the difference value of the current outdoor fan rotating speed to the preset maximum rotating speed of the outdoor fan is smaller than the preset difference value or not; if the difference value is smaller than the preset difference value, the rotating speed of the outdoor fan is kept unchanged; and if the difference value is larger than or equal to the preset difference value, increasing the rotating speed of the outdoor fan.
Preferably, the current rotating speed of the outdoor fan is n, the maximum rotating speed nmax is preset for the water pumping motor, and the difference value between the current rotating speed of the water pumping motor and the maximum rotating speed is recorded as Δ n, where Δ n is nmax-n, and Δ n is greater than or equal to (0-10%) nmax.
When the higher dewatering of the rotational speed of the motor of fetching water is very fast, can keep the full protection of water rotational speed and carry out the dewatering, when the lower dewatering of motor rotational speed is slower, through the rotational speed that improves outdoor fan and the motor of fetching water, with the motor of fetching water in coordination with the dewatering for the speed of water collector dewatering shortens the stand-by time of compressor.
According to the embodiment, through the prejudgment of any one of the three modes, the problem that the compressor is frequently started and stopped due to the fact that the accumulated water is fast enough to protect the water when the water level of the water receiving tray is lower than the warning water level and the compressor is recovered to operate can be solved; the water plate does not need to be manually drained, so that the automation and the intellectualization are realized; meanwhile, the water accumulation time in the water receiving tray during the working of the compressor is prolonged, so that the compressor can work for a long time, and the user experience is enhanced.
Example 2
The embodiment provides a water fullness protection control method for an air conditioning unit, as shown in fig. 3, the air conditioning unit is provided with a water pan for collecting condensed water, a water-fetching flywheel for fetching the condensed water in the water pan to a condenser, and a water-fetching motor for providing power for the flywheel, when the water level of the water pan is greater than or equal to a warning water level, the air conditioning unit is triggered to carry out water fullness protection and control as follows: stopping the compressor; increasing the rotating speed of the water fetching motor; the method comprises the steps of collecting the water level of a water receiving tray and the load of a water pumping motor in real time, and determining the reset time of a compressor based on the water level of the water receiving tray and the load of the water pumping motor.
Because the load of the water fetching motor is reduced along with the reduction of the draught depth of the water fetching flywheel, the reset water level of the water receiving tray can be judged in advance through the water level of the water receiving tray and the load of the water fetching motor so as to determine the reset time of the compressor.
Preferably, the real-time collection of the water level of the water pan and the load of the water pumping motor, and the determination of the compressor reset time based on the water level of the water pan and the load of the water pumping motor comprise: judging whether the water level of the water receiving tray is smaller than a warning water level or not; and if the water level of the water receiving tray is smaller than the warning water level, continuously judging whether the load of the water fetching motor is smaller than the preset load of the water fetching motor and/or whether the load reduction rate of the water fetching motor is larger than the preset load reduction rate of the water fetching motor.
And if the water level of the water receiving tray is smaller than the warning water level, continuously judging whether the load of the water fetching motor is smaller than the preset load of the water fetching motor and/or whether the load reduction rate of the water fetching motor is larger than the preset load reduction rate of the water fetching motor.
When the compressor is reset, the water level of the water receiving tray is a reset water level, and the reset water level is set to be lower than the warning water level.
In this embodiment, the water level of the water tray is pre-determined to determine the time for recovering the start of the compressor, and specifically, there may be three methods:
firstly, when the water level of a water receiving tray is smaller than the warning water level, judging whether the real-time load of a water fetching motor is smaller than the preset water fetching motor load, when the condition is met, the time taken for the water fetching motor to be fully protected until the condition is met is the resetting operation time of a compressor, wherein the load of the water fetching motor can be (0.3-0.5) G of the preset water fetching motor load, and G is the load of a water fetching flywheel at the warning water level;
and secondly, when the water level of the water receiving tray is smaller than the warning water level, whether the load reduction rate of the water fetching motor is larger than the preset load reduction rate of the water fetching motor or not is judged, and when the condition is met, the time for the water full protection to meet the condition is the compressor reset operation time.
Thirdly, when the two conditions are met, the used time is the compressor reset operation time.
The load G1 of the water fetching motor is determined by the following functional relation:
G1＝(ρ,g,h,R,n,e)
wherein rho is the density of water, g is the gravity acceleration, h is the draft, R is the radius of the water beating flywheel, n is the rotation speed of the water beating motor, and e is a correction coefficient.
In order to shorten the standby time of the compressor, the standby time can be shortened by increasing the rotating speed of the water fetching motor. Specifically, the increasing of the rotation speed of the water beating motor comprises the following steps: judging whether the difference value of the rotating speed of the current water beating motor compared with the preset maximum rotating speed of the water beating motor is smaller than a preset difference value or not; if the difference value is smaller than the preset difference value, the rotating speed of the water fetching motor is kept unchanged; and if the difference value is larger than or equal to the preset difference value, increasing the rotating speed of the water fetching motor.
Preferably, the rotating speed of the current water fetching motor is V, the maximum rotating speed Vmax of the water fetching motor is preset, the difference value of the rotating speed of the current water fetching motor and the maximum rotating speed is recorded as delta V, the delta V is Vmax-V, and the delta V is larger than or equal to (0-10%) Vmax.
Optionally, the water fetching motor is a direct current motor, and the rotation speed of the water fetching motor is increased by changing the voltage of the water fetching motor, namely, the input voltage of the water fetching motor is increased, so that the rotation speed of the water fetching motor is increased.
In order to further accelerate the water removal of the water receiving tray, when the water level of the water receiving tray is larger than or equal to the warning water level, the step of triggering the air conditioning unit to be full of water and protecting further comprises the step of increasing the rotating speed of an outdoor fan. When the water collector water level is greater than or equal to the warning water level, trigger the full water protection of air conditioning unit and still include the rotational speed that risees outdoor fan, include: the increasing of the rotating speed of the outdoor fan specifically comprises the following steps: judging whether the difference value of the current outdoor fan rotating speed to the preset maximum rotating speed of the outdoor fan is smaller than the preset difference value or not; if the difference value is smaller than the preset difference value, the rotating speed of the outdoor fan is kept unchanged; and if the difference value is larger than or equal to the preset difference value, increasing the rotating speed of the outdoor fan.
Preferably, the current rotating speed of the outdoor fan is n, the maximum rotating speed nmax is preset for the water pumping motor, and the difference value between the current rotating speed of the water pumping motor and the maximum rotating speed is recorded as Δ n, where Δ n is nmax-n, and Δ n is greater than or equal to (0-10%) nmax.
