Embodiment one
Fig. 2 is the flow diagram of the control method of air conditioner in one embodiment disclosed in the present application.As shown in Fig. 2,
The control method of the air conditioner of the embodiment of the present application, specifically includes the following steps:
S21, the first refrigerant concentration for obtaining indoor refrigerant.
Specifically, the coolant quantity of leakage can be detected by the sensor in air conditioner.Then, according to the coolant quantity of leakage
Ratio between the volume of current indoor, it can determine the first refrigerant concentration of indoor refrigerant.
S22, detection simultaneously determine that the first refrigerant concentration is greater than the first concentration threshold, then the fresh air system controlled in air conditioner opens
It is dynamic.
Specifically, it is compared by the first refrigerant concentration for getting indoor refrigerant with the first concentration threshold, when it is big
When the first concentration, show that the concentration of current indoor refrigerant is excessive, at this point, the fresh air system starting in air conditioner is then controlled, with
Accelerate indoor and outdoor air circulation, so that indoor refrigerant is discharged to outdoor, reduces indoor refrigerant concentration, improve indoor air
Quality.Wherein, the first concentration threshold is preset concentration value.
In conclusion the control method of air conditioner provided by the embodiments of the present application, when detect indoor refrigerant first cold
When matchmaker's concentration is greater than the first concentration threshold, the fresh air system starting in air conditioner is controlled, to accelerate indoor and outdoor air circulation, thus
Indoor refrigerant is discharged to outdoor, indoor refrigerant concentration is reduced, improves indoor air quality.
It should be noted that control fresh air system starting when, can control the motor in fresh air system rotate forward or
It rotates backward.It wherein, is that outdoor air is blowed into interior when the motor in fresh air system rotates forward；And it is reversed
It is then that indoor air is blowed into outdoor when rotation.
It is controlled in air conditioner simultaneously or after control motor is counter-rotational as a kind of possible implementation
Indoor fan and/or wind deflector are closed in outdoor unit power-off, and/or control air conditioner, to reduce the flow direction of the refrigerant in air conditioner
Indoor speed.
Optionally, after the motor in control fresh air system rotates backward, concentration that can also again to indoor refrigerant
It is detected.For the ease of distinguishing, the refrigerant concentration obtained at this time is known as the second refrigerant concentration.
Wherein, when the motor reversal in fresh air system for a period of time after, if detecting that the second refrigerant concentration is still greater than
First concentration threshold illustrates that the coolant leakage amount in air conditioner is larger.Since air conditioner inner space is limited, work as leakage
Refrigerant when gathering excessive in air conditioner, the concentration of refrigerant will be gradually increased in air conditioner, this is easy for that air conditioner is caused to go out
The risk now burnt.In order to avoid the appearance of above situation, motor is then controlled at this time and is rotated forward, and control indoor in air conditioner
Blower is opened, and wind deflector is opened to maximum air outlet angle in control air conditioner, and air conditioner will utmostly be accumulated
The refrigerant gathered in air conditioner is purged to outside air conditioner, to reduce local refrigerant concentration in air-conditioning, avoids the refrigerant of leakage
Assemble inside air-conditioning.
In addition, if the second refrigerant concentration is less than or equal to the first concentration threshold, then show not gather in current air conditioner
Excessive refrigerant.But continue to detect the concentration of indoor refrigerant in order to which safety can choose at this time.

Indoor fan in device is adjusted to open, and wind deflector is opened in control air conditioner, outdoor air introducing is indoor, to increase room
Interior air pressure, indoors under the action of external differential, indoor air will flow to outdoor by the gap in room, to reduce
The concentration of indoor refrigerant improves indoor air quality.
Further, in order to increase the speed that outdoor air enters the room, it can control wind deflector and open to maximum outlet air
Angle.
On the basis of above-described embodiment, can also the concentration again to indoor refrigerant detect.For the ease of area
Point, the refrigerant concentration obtained at this time is known as third refrigerant concentration.
Wherein, after motor rotates forward a period of time, if detecting that third refrigerant concentration is less than or equal to second
Concentration threshold and it is greater than third concentration threshold, then controls motor and indoor fan and continue current operating conditions, and control wind-guiding
Plate swings air-supply, bobs and weaves air-supply for example, can control wind deflector.It can thus continue to avoid wind deflector to one
Angle blowing, and appearance the case where cause indoor a certain region refrigerant excessive concentration.That is, being swung by control wind deflector
The case where air-supply, can make refrigerant uniformly diffuse to indoor each corner, avoid indoor local refrigerant excessive concentration appearance.
Wherein, the second concentration threshold is less than or equal to the first concentration threshold, and third concentration threshold is less than or equal to the second concentration threshold
Value.
If detecting that third refrigerant concentration is less than or equal to third concentration threshold, show the concentration of current indoor refrigerant
It has already decreased to a certain degree, can only need fresh air system self-operating at this time, so that it may maintain indoor air quality；?
That is can control indoor fan closing at this time, and motor is maintained to continue to rotate forward.Further, in a period of time
Afterwards, if detect again indoor refrigerant excessive concentration when, can execute above-mentioned according to section where existing concentration, selection
Corresponding step.
In addition, if third refrigerant concentration is greater than the second concentration threshold, then show the concentration of current indoor air refrigerant according to
So larger, therefore, it is necessary to continue to detect the concentration of indoor refrigerant.
Further, it after control wind deflector swings air-supply, can also continue to examine the concentration to indoor refrigerant
It surveys.For the ease of distinguishing, the refrigerant concentration obtained at this time is known as the 4th refrigerant concentration.
Wherein, after controlling wind deflector swing air-supply a period of time, if detecting that the 4th refrigerant concentration is less than or waits
In third concentration threshold, show that the concentration of current indoor refrigerant has already decreased to a certain degree, can only need fresh air system at this time
System self-operating, so that it may maintain indoor air quality；That is, can control indoor fan closing at this time, and tie up
Motor is held to continue to rotate forward；.Further, over time, if detect again indoor refrigerant excessive concentration when,
Then above-mentioned corresponding step can be executed according to section where existing concentration, selection.
In addition, if the 4th refrigerant concentration is greater than third concentration threshold, then need to continue to carry out the concentration of indoor refrigerant
Detection.
It should be understood that being to detect the second refrigerant concentration, third again again after certain interval of time in the application
Refrigerant concentration and the 4th refrigerant concentration.
