Referring to fig. 1, an embodiment of the present disclosure provides a control method for dehumidifying an air conditioner, including the steps of:

s101, obtaining target indoor environment temperature, real-time indoor environment humidity and real-time air conditioner indoor coil temperature.

In practical application, real-time temperature and humidity acquisition is performed through a temperature and humidity sensor. For example, a temperature sensor disposed near the indoor coil is used to obtain real-time air conditioner indoor coil temperature and a humidity sensor is used to obtain real-time indoor ambient humidity. Here, the target indoor environment temperature is an indoor environment temperature that the user wants to reach.

S102, determining the temperature of the indoor coil of the target air conditioner according to the target indoor environment temperature and the real-time indoor environment humidity.

Because the dew point temperature varies with the variation of humidity, the present disclosure, when calculating the target indoor coil temperature, determines together by the target indoor environment temperature and the real-time indoor environment humidity, thereby better achieving air conditioning dehumidification according to the target indoor coil temperature.

S103, determining a first target operating frequency of the air conditioner compressor according to a coil temperature difference between the target air conditioner indoor coil temperature and the real-time air conditioner indoor coil temperature.

Optionally, determining the first target operating frequency of the air conditioner compressor according to a coil temperature difference between the target air conditioner indoor coil temperature and the real-time air conditioner indoor coil temperature includes: and determining a first target operating frequency in a PID calculation mode according to the coil temperature difference.

PID calculation mode, namely proportional integral differential control, integrates three functions of proportional, integral and differential, can accelerate the response speed of the system, reduce oscillation, overcome overshoot, effectively eliminate static difference and greatly improve the static and dynamic quality of the system. The target operating frequency of the compressor is determined in a PID calculation mode, so that the dehumidification of the air conditioner is realized, and the dehumidification control of the air conditioner can be more accurate and stable.

S104, controlling the air conditioner compressor to operate according to the first target operating frequency, and reducing the temperature of the indoor coil pipe of the air conditioner so as to condense water vapor in the air.

In practical application, the air conditioner compressor is controlled to operate according to a first target operating frequency, so that the indoor coil is at a locally lower temperature near the evaporator, and because the temperature is lower than the dew point temperature of room air, water vapor in the air near the indoor coil condenses to form water drops, and the water drops flow to the drainage groove along the evaporator slideway to be discharged out of the room, thereby realizing the dehumidification of the air conditioner.

By adopting the control method for air conditioner dehumidification provided by the embodiment of the disclosure, firstly, the temperature of the indoor coil of the air conditioner is determined according to the target indoor environment temperature and the real-time indoor environment humidity, then, the target operating frequency of the air conditioner compressor is determined according to the coil temperature difference between the temperature of the indoor coil of the air conditioner and the temperature of the indoor coil of the real-time air conditioner, and the air conditioner compressor is controlled to operate according to the target operating frequency, so that the temperature of the indoor coil of the air conditioner is reduced to condense water vapor in the air, and the air conditioner dehumidification is realized. Therefore, the dehumidification reference factor is adjusted, the target operating frequency of the air conditioner compressor is determined through the coil temperature difference between the temperature of the indoor coil of the target air conditioner and the temperature of the indoor coil of the real-time air conditioner, and the operation of the air conditioner compressor is controlled, so that the accurate dehumidification can be realized, and the dehumidification effect of the air conditioner is remarkably improved.

Referring to fig. 2, an embodiment of the disclosure provides a control method for dehumidifying an air conditioner, which determines a target indoor coil temperature of the air conditioner according to a target indoor environment temperature and a real-time indoor environment humidity, comprising the steps of:

s201, determining the real-time dew point temperature according to the target indoor environment temperature and the real-time indoor environment humidity.

The dew point temperature is simply the temperature at which vapor condenses into dew in the atmosphere. Because the atmosphere has a limited capacity to carry water vapor, generally the higher the temperature, the more water vapor is carried. When the water vapor amount is unchanged and the air temperature is reduced to a certain degree, the water vapor is saturated, and the critical temperature is the dew point temperature.

The dew point temperature is related to the ambient humidity, so the present disclosure determines a real-time dew point temperature according to the target indoor ambient temperature and the real-time indoor ambient humidity, and then can more accurately perform air conditioning dehumidification control according to the real-time dew point temperature.

Optionally, determining the real-time dew point temperature according to the target indoor environment temperature and the real-time indoor environment humidity includes: filtering the real-time indoor environment humidity to obtain the filtered real-time indoor environment humidity; and determining the real-time dew point temperature according to the target indoor environment temperature and the filtered real-time indoor environment humidity.

The filtering processing for the real-time indoor environment humidity comprises the following steps: acquiring the average indoor environment humidity of the previous N times of real-time indoor environment humidity; and taking the average value of the real-time indoor environment humidity of the previous two times as the real-time indoor environment humidity of the current time under the condition that the humidity difference value between the real-time indoor environment humidity and the average indoor environment humidity is larger than the preset humidity difference value. Here, N is an integer greater than or equal to 2.

For example, the real-time indoor environment humidity detected N times before (e.g., 5 times before) is 70%, 68%, 66%, 64%, 62%, respectively, and the average indoor environment humidity is 66%. When the preset humidity difference is 5%, if the real-time indoor environment humidity at this time is 88%, the humidity difference between the real-time indoor environment humidity and the average indoor environment humidity is 22% (greater than the preset humidity difference by 5%), and then the average value 63% of the real-time indoor environment humidity at the previous two times (64% and 62%, respectively) is taken as the real-time indoor environment humidity at this time.

By carrying out filtering treatment on the real-time indoor environment humidity, the accuracy of influencing the real-time dew point temperature by the obvious abnormal real-time indoor environment humidity data can be avoided, so that the running stability of the follow-up air conditioner compressor is improved, the service life of the compressor is prevented from being damaged by severe fluctuation of the compressor frequency, and the influence of unstable running of the air conditioner on the use experience of a user is also avoided as much as possible.

Table 1 below shows a table of preset correspondences for an alternative target indoor ambient temperature, real-time indoor ambient humidity and real-time dew point temperature. Based on the target indoor environment temperature and the real-time indoor environment humidity (the real-time indoor environment humidity subjected to the filtering treatment), the real-time dew point temperature corresponding to the target indoor environment temperature and the real-time indoor environment humidity can be determined by searching the following preset corresponding relation table. For example, the target indoor environment temperature is 15 ℃, the real-time indoor environment humidity is 32%, and the real-time dew point temperature is-1.4 ℃.

TABLE 1 preset correspondence table

S202, determining a real-time dew point temperature compensation value according to the rotating speed of the indoor fan of the air conditioner.

The effect of moisture condensation is also related to wind speed at certain ambient temperature and humidity. Generally, the higher the wind speed, the faster the air flow at the indoor coil of the air conditioner, and the faster the water vapor condenses; the lower the wind speed, the slower the air flow at the indoor coil of the air conditioner and the slower the water vapor condensation. Therefore, the real-time dew point temperature compensation value is determined according to the rotational speed (wind speed) of the indoor fan of the air conditioner.

In practical application, a corresponding relation table of the rotating speed of the air conditioner indoor fan and the real-time dew point temperature compensation value can be established, and the real-time dew point temperature compensation value corresponding to the rotating speed of the air conditioner indoor fan can be determined by searching the corresponding relation table of the rotating speed of the air conditioner indoor fan and the real-time dew point temperature compensation value.

S203, determining the temperature of the indoor coil of the target air conditioner according to the real-time dew point temperature and the real-time dew point temperature compensation value.

Optionally, determining the target air conditioning indoor coil temperature based on the real-time dew point temperature and the real-time dew point temperature compensation value includes determining the target air conditioning indoor coil temperature according to the following formula:

T _m ＝T _s +α×ΔT _b

wherein T is _m For the temperature of the indoor coil pipe of the air conditioner, T _s For real-time dew point temperature, alpha is the real-time dew point temperature compensation value coefficient, delta T _b Is a real-time dew point temperature compensation value.

At real time dew point temperature offset DeltaT _b When the temperature is larger than the preset compensation value (for example, 2 ℃), the real-time dew point temperature compensation value coefficient alpha and the real-time dew point temperature compensation value delta T _b Negative correlation, i.e. DeltaT _b The smaller the α, the larger the α; delta T _b The larger the α, the smaller the α. In this way, real-time dew point temperature compensation value DeltaT is avoided _b Too much adversely affects the accuracy of the target air conditioning indoor coil temperature Tm.

In the embodiment of the disclosure, the target indoor coil temperature of the air conditioner is comprehensively determined according to the target indoor environment temperature and the real-time indoor environment humidity, and the target indoor coil temperature is compensated by utilizing the rotating speed of the indoor fan, so that the temperature factor on which the air conditioner dehumidifies can be more accurately determined, thereby realizing the accurate dehumidification of the air conditioner and improving the dehumidification effect of the air conditioner.

The second target operating frequency is obtained in a similar manner to the first target operating frequency. The method specifically comprises the following steps: in a plurality of (DeltaT 2) _n ，Q _n ) The fitting point is subjected to linear fitting to form a reference curve between the first ambient temperature difference value and the refrigerating capacity; wherein DeltaT2 _n For the nth first ambient temperature difference, Q _n Is equal to delta T2 _n The corresponding nth refrigeration capacity; randomly selecting a plurality of reference points from the reference curve, taking the refrigerating capacity of the reference points as constant value refrigerating quantity value, and taking a first environmental temperature difference value of the reference points as constant value parameter; adjusting the rotating speed of an indoor fan of the air conditioner and the running frequency of a compressor of the air conditioner until the refrigerating energy efficiency ratio COP reaches the highest; collecting the rotating speed of an air conditioner indoor fan and the frequency of an air conditioner compressor under the working condition of the highest refrigeration energy efficiency ratio COP to obtain an optimal state point (delta T) _n ，R _n ，F _n ) The method comprises the steps of carrying out a first treatment on the surface of the Wherein R is _n Is the rotation speed of an nth air conditioner indoor fan, F _n An nth air conditioner compressor frequency; all the optimal state points (DeltaT _n ，R _n ，F _n ) Performing surface fitting to obtain a fitting curve; and determining the frequency of the air conditioner compressor corresponding to the first environmental temperature difference value as a second target operating frequency based on the fitted curve.
