and S101, detecting the air conditioner airtightness.
S102, under the condition that the air conditioner is poor in air tightness, adjusting the working frequency of the compressor to a set frequency, and/or adjusting the rotating speed of the indoor fan to a set rotating speed.
In some embodiments, the set frequency is a compressor minimum operating frequency. In some embodiments, the set frequency is 0.2f to 0.5f, where f is the maximum operating frequency of the compressor.
In some embodiments, the set speed is a maximum fan speed. In some embodiments, the set wind speed is 0.2S to 0.5S, where S is the maximum rotational speed of the indoor fan.
In some embodiments, the detecting of the air-conditioning airtightness in step S101 includes: detecting the indoor environment temperature and the current of an indoor fan; and under the condition that the current of the indoor fan and the set current corresponding to the indoor environment temperature meet the preset condition, determining that the air conditioner is poor in air tightness.
In some embodiments, the preset conditions include: the current of the indoor fan is larger than the set current corresponding to the indoor environment temperature.
In the embodiment of the disclosure, the air-conditioning tightness is detected, the air-conditioning is easy to leak under the condition of poor tightness, at the moment, condensation is easy to generate on the surface of the evaporator due to the fact that air does not pass through the evaporator, and the air-conditioning is dripped and blown out along with the air when a large amount of condensation is collected. Under the condition that the air conditioner is poor in airtightness, excessive condensation generated on the surface of the evaporator is avoided by adjusting the working frequency of the compressor or adjusting the rotating speed of the indoor fan to a set state, and the occurrence of water drops blown out by the air conditioner is reduced.
Fig. 2 is a schematic diagram of another method for air conditioning control according to an embodiment of the present disclosure, including the following steps:
s201, detecting the uniformity of air conditioner shunting.

When the difference Δ t1 is greater than the difference Δ t2, the temperature of the evaporator coil is detected to be higher in a flow path with less refrigerant liquid separation, and at this time, the temperature of a low-temperature pipeline is further reduced due to the fact that the working frequency of the compressor is continuously increased, so that the risk of air conditioner blowing water drops exists. In some embodiments, reducing the operating frequency of the compressor can reduce the difference between a pipeline with a large amount of liquid refrigerant and a pipeline with a small amount of refrigerant, and reduce the generation of condensation, thereby reducing the occurrence of air conditioner blown water drops. In some embodiments, the rotation speed of the indoor fan is increased to accelerate air disturbance around the evaporator, so that water drops are prevented from being attached to the surface of the evaporator, condensation is reduced, and the occurrence of water drops blown out by the air conditioner is reduced. In some embodiments, the working frequency of the compressor is reduced, and the rotating speed of the indoor fan is increased, so that the generation of condensation is reduced to a greater extent, and the generation of water drops blown out by the air conditioner can be reduced more effectively.
Under the condition that the difference value delta t1 is larger than the difference value delta t2, the evaporator coil is in a flow path with a large amount of liquid-separating refrigerant, at the moment, the risk that the air conditioner blows out water drops is low, the working frequency of the compressor is improved, the refrigeration efficiency and the dehumidification efficiency can be improved, the comfort level of the indoor environment is improved, and the user experience is improved.
In some embodiments, the operating frequency of the compressor is reduced by a first frequency adjustment; increasing the working frequency of the compressor according to the second frequency adjustment quantity; wherein the first frequency adjustment amount is greater than the second frequency adjustment amount.
Wherein, the first frequency adjustment quantity is large, so that the surface temperature of the evaporator can be accelerated to reduce condensation. The second frequency adjustment volume is little and avoids the air-out temperature fluctuation big, improves the comfort level of air-out, avoids bringing bad experience for the user.
In this disclosed embodiment, detect the homogeneity of air conditioner reposition of redundant personnel, the air conditioner can be because the difference in temperature between different flow paths leads to the production of comdenstion water when the reposition of redundant personnel is uneven, adjusts the operating frequency of compressor or adjusts the rotational speed of indoor fan when the reposition of redundant personnel is uneven, avoids the big too much condensation that generates of evaporimeter surface difference in temperature, has reduced the air conditioner and has blown out the emergence of drop of water.

Wherein, the coil temperature, the return air temperature and the first difference value delta t1 satisfy the following relations:
Δt1＝Th1-Tp1
where Δ T1 is a first difference, Th1 is the coil temperature at a first time point T1, and Tp1 is the return air temperature at the first time point.
The coil temperature, the return air temperature and the second difference value delta t2 satisfy the following relation:

However, when the difference Δ t1 is larger than the difference Δ t2, the evaporator coil may be in a flow path with a small amount of refrigerant separated, and at this time, air conditioner blown water drops may occur. In some embodiments, reducing the operating frequency of the compressor may increase the temperature of the evaporator surface to reduce the generation of condensation, thereby reducing the occurrence of air conditioner blow-off water droplets. In some embodiments, the rotation speed of the indoor fan is increased to accelerate air disturbance around the evaporator, so that water drops are prevented from being attached to the surface of the evaporator, condensation is reduced, and the occurrence of water drops blown out by the air conditioner is reduced. In some embodiments, the working frequency of the compressor is reduced, and the rotating speed of the indoor fan is increased, so that the generation of condensation is reduced to a greater extent, and the generation of water drops blown out by the air conditioner can be reduced more effectively.
