Fig. 1 is the flow chart according to the coolant leakage control method of the air-conditioning of the embodiment of the present application.As shown in Figure 1, according to
The coolant leakage control method of the air-conditioning of the application one embodiment, includes the following steps:
S101: the refrigerant state on predetermined sampled point is detected.
In specific example, refrigerant state includes but is not limited to the change rate of refrigerant concentration and refrigerant concentration, wherein refrigerant
The change rate of concentration can be obtained according to the concentration difference of the refrigerant concentration in scheduled time interval.
Refrigerant concentration can detect to obtain by corresponding sensor.Predetermined sampled point refers to outside the medium circulation pipeline of refrigerant
Some several position, such as: comparatively sensor arrangement is easy to happen refrigeration in the medium circulation pipeline of refrigerant
The line connection of agent leakage, so that the refrigerant concentration of leakage can be effectively detected when refrigerant leaks.
By taking sensor sample refrigerant concentration as an example, due to the requirement such as sensor design specification, there is certain sampling period,
Such as 1 second, then sensor can be at interval of the refrigerant concentration of sampling in 1 second.
Such as: can be using current time as the first moment, sensor is once sampled, and the second moment can be
Start timing when one moment, at the time of after scheduled time interval, time interval should be one or more refrigerant concentration and adopt
In the sample period, if the sampling period is 1 second, then time interval is 1 second integer multiple.
As shown in Fig. 2, the sampling period for 1 second, in this five sampling instants of moment t0, t1, t2, t3, t4, samples
Refrigerant concentration be respectively w0, w1, w2, w3, w4.Wherein, t0, t1, t2, t3, t4 can be one sampling period of every process (such as
1 second) sampling, it is of course also possible to be sampled by multiple sampling periods (such as 3 sampling periods, it may be assumed that 3 seconds).
In the example of the application, if moment t0 was the first moment, moment t1 was the second moment, then the first moment t0's is cold
Matchmaker's concentration is w0, and the refrigerant concentration of the second moment t1 is w1.
The change rate of refrigerant concentration refers to the slope of the concentration changes with time of refrigerant.With the refrigerant concentration of the second moment t1
For change rate, then as shown in connection with fig. 2, if the sampling period is 1 second, t0 to t1 passes through a sampling period, then the second moment t1
Time interval with the first moment t0 is 1 second, then when the second moment t1, and refrigerant change rate of concentration can be real by following formula
It is existing, the formula are as follows:
dwt1=(w1-w0)/(t1-t0),
Wherein, dwt1Refer to the refrigerant change rate of concentration of the second moment t1, to obtain the refrigerant concentration variation of the second moment t1
Rate.
It should be noted that the refrigerant change rate of concentration at other moment can also obtain in the same way, herein no longer
It illustrates one by one.
S102: when refrigerant leaks, corresponding leakage class is determined according to refrigerant state.
Such as the corresponding grade of slight leakage, the corresponding grade of serious leakage.As a specific example, example
If leakage class includes slight danger classes and severe danger grade, then when refrigerant concentration is greater than first threshold or refrigerant concentration
Change rate be greater than second threshold when, determine leakage class be slight danger classes, when refrigerant concentration be greater than third threshold value or
When the change rate of refrigerant concentration is greater than four threshold values, determine that leakage class is severe danger classes, wherein third threshold value is greater than the
One threshold value, the 4th threshold value are greater than second threshold.Wherein, first threshold to the 4th threshold value can be determined according to experiment, can also root
It is set according to experience.
That is, being said when refrigerant concentration is greater than the change rate of first threshold or refrigerant concentration greater than second threshold
The slower perhaps slight leakage of the speed of bright leakage is greater than when the change rate that refrigerant concentration is greater than third threshold value or refrigerant concentration
When four threshold values, illustrate leakage rate comparatively fast or leakage than more serious.Wherein, first threshold to the 4th threshold value can root
Determination is factually tested, can also rule of thumb be set.
S103: wind-guiding aperture is controlled according to leakage class, or wind-guiding aperture and wind-guiding wind speed are controlled.
It wherein, can be opening by way of opening and closing the wind blade of indoor unit wind-guiding to the control of wind-guiding aperture
Degree is controlled, and further, can also be the control of wind-guiding aperture by the adjusting to wind blade, wind-guiding aperture is made to exist
In any aperture between maximum wind-guiding aperture and minimum wind-guiding aperture, for example, can be according to the needs of current wind-guiding amount, it will
Wind-guiding aperture regulation is to corresponding aperture, it should be noted that in general, be maximum wind-guiding aperture when wind-guiding aperture standard-sized sheet, when
It is minimum wind-guiding aperture when wind-guiding aperture is closed, the starting and closing of indoor fan, wind can be passed through to the control of wind-guiding wind speed
The modes such as machine rotational speed regulation are controlled, certainly, can also be by individual fresh air system in the other examples of the application
It is controlled to adjust wind-guiding wind speed, such as: fresh air system is sent instructions to, so that fresh air system is run, is come with this to interior
Air-flow controlled, accelerate air-flow flowing, it may be assumed that accelerate leakage refrigerant diffusion.
By taking slight danger classes and the corresponding control of severe danger grade as an example, then if it is slight danger classes, control
The wind blade of indoor unit processed is opened, and carries out level-one alarm, and if it is severe danger grade, the wind blade of indoor unit is opened
While opening, indoor fan and/or fresh air system operation are further controlled, and carry out secondary alarm.
Wherein, reach secondary alarm it is opposite reach level-one alarm illustrate to leak it is even more serious, therefore, in the specific of the application
In example, type of alarm can also be different, distinguish alarm level with this, user is allow to quickly understand leakage situation, such as: when
When alarming for level-one, light or audible alarm are carried out, when for secondary alarm, alarm while light and sound.That is:
Bright, light flash or sound etc. if it is single light illustrate that relatively slight leakage occurs.When for secondary alarm
When, carry out light and sound while alarm, as light is bright and sound simultaneously or light flash and sound simultaneously, at this point, saying
It is bright that relatively serious leakage occurs.
That is, illustrating that leakage rate is slower when for slight danger classes, at this point, by opening wind blade
The refrigerant of leakage can be diffused into air by gravity-flow ventilation, avoid local refrigerant excessive concentration by mode.When for severe
When danger classes, illustrate leakage rate quickly, it cannot in a manner of making gravity-flow ventilation individually through wind blade is opened
The refrigerant effectively leaked is diffused into air, at this point, opening indoor fan accelerates ventilation, to avoid local refrigerant concentration mistake
It is high.
If it is combustible refrigerant, excessive concentration may cause catches fire refrigerant, and therefore, the mode of the embodiment of the present application can have
Effect reduces refrigerant concentration and promotes the safety of air-conditioning to avoid catching fire, meanwhile, the unnecessary unlatching such as indoor fan is avoided, is kept away
Exempt from the waste of energy consumption, and indoor fan is avoided frequently to open, and then promotes the service life of air-conditioning.
According to the coolant leakage control method of the air-conditioning of the embodiment of the present application, refrigerant concentration can be effectively reduced, to avoid
It catches fire, promotes the safety of air-conditioning, meanwhile, the unnecessary unlatching such as indoor fan is avoided, the waste of energy consumption is avoided, and avoids room
Inner blower is frequently opened, and then promotes the service life of air-conditioning.
When refrigerant leaks, in order to allow users to find in time, to take timely counter-measure, the application is real
It applies in the method for example, further includes: coolant leakage is reported to prompt the intelligent terminal to server and/or user.To, user or
Refrigerant leakage failure occurs for the air-conditioning that can learn user at the first time after sale of air-conditioning, can repair in time
Deng, promoted after-sale service quality, promote the user experience of air-conditioning.
It should be noted that by the change rate of refrigerant concentration and refrigerant concentration can determine refrigerant whether leak and
In comparison leakage class determines whether refrigerant leaks according to the change rate of refrigerant concentration, can eliminate refrigerant concentration sample
The influence for the judging result whether error leaks refrigerant, this is because, no matter sampling with the presence or absence of error, even if sampling
There are errors, such as error can effectively be disappeared in (- 0.2 ,+0.2) by the judgement of the change rate to refrigerant concentration of preset value
Influence except error to testing result can accurately judge whether refrigerant is let out according to the change rate of refrigerant concentration as a result,
Leakage.
In addition, the time difference since the sampling period is very short (such as Millisecond), between the first moment and the second moment
Controllably in the very short time, therefore, determine whether refrigerant leaks according to the change rate of refrigerant concentration, it can also be in the very short time
The judgement that coolant leakage is completed in interior (such as 0.3 second) has the advantages that detection is fireballing.
As shown in connection with fig. 2, the standard as used concentration 1 and concentration 2 to judge whether refrigerant leaks (i.e. according to refrigerant concentration)
When, it can be seen that although response speed is very fast at the time of A point corresponds to, since the value of concentration 1 is smaller, when there are one for sampling
It when determining deviation, be easy to cause erroneous judgement, fail to judge, influence the accuracy of coolant leakage judgement, although concentration value is big at the time of C point corresponds to
In concentration 2, i.e. concentration is larger, can eliminate influence of the sampling error to accuracy is judged, still, response speed to a certain extent
Slowly, t3 moment, even longer time are such as had already passed through, it may be assumed that detection time is long.
And when determining whether refrigerant leaks according to the change rate of refrigerant concentration, it can accurately can sentence at the t1 moment
Whether disconnected refrigerant out leaks, and response speed is relatively fast.
As shown in Fig. 3 to 6, respectively in the coolant leakage control method of the air-conditioning of the embodiment of the present application, four kinds of determinations are let out
Leak the example of grade, wherein Fig. 3 is the example that slight danger classes and severe danger grade are determined according to refrigerant concentration.Fig. 4 is
