Referring to fig. 4, an embodiment of the present disclosure provides a method for dehumidifying an air conditioner, including:

s210, detecting the current temperature of the coil by the first temperature sensor.

And S220, determining the target opening degree of the first regulating valve by the processor according to the current temperature of the coil, the historical temperature of the coil and the current opening degree of the first regulating valve.

And S230, the processor adjusts the opening degree of the first regulating valve to be a target opening degree.

By adopting the method for dehumidifying the air conditioner provided by the embodiment of the disclosure, the first evaporator is used for dehumidifying, the second evaporator is used for air circulation, and the air conditioner can prevent the normal operation of the compressor from being influenced by the fast drop of the indoor temperature while dehumidifying. The opening of the first regulating valve is adjusted along with the change of the temperature of the coil pipe, the refrigerant circulation of the first evaporator is changed, and then the dehumidification speed is accelerated, so that the dehumidification efficiency of the air conditioner is improved.

The method for dehumidifying the air conditioner provided by the embodiment of the disclosure is to adjust the opening degree of the first adjusting valve according to the temperature of the coil. Compared with a method for dehumidifying according to the indoor environment temperature or the set temperature, the air conditioner is less affected by the indoor environment temperature when dehumidifying. Since the temperature of the coil is lower than the indoor ambient temperature, a good dehumidification effect can be achieved even when the indoor ambient temperature is low (for example, 16 ℃).

Alternatively, the historical temperature may be the current temperature of the coil in the last control or an average of the current temperatures of the coils in previous controls.

Optionally, the processor in step S220 determines the target opening degree of the first adjusting valve according to the current temperature of the coil, the historical temperature of the coil, and the current opening degree of the first adjusting valve, and includes: the processor determines a difference between the current temperature and the historical temperature of the coil. And the processor determines the target opening degree of the first regulating valve according to the temperature difference value of the coil pipe and the current opening degree of the first regulating valve.

Optionally, the processor determines a target opening degree of the first regulating valve according to the coil temperature difference value and the current opening degree of the first regulating valve, and includes: y is_n＝Y_n-1+|△T|×Y_p+△T×α×Y_p. Wherein, T ═ T_n-T_n-1，Y_nIs a target opening degree of the first regulating valve, Y_n-1Is the current opening of the first regulating valve, T_nIs the current temperature of the coil, T_n-1The historical temperature of the coil, delta T is the temperature difference of the coil, alpha is the opening correction coefficient, Y_pThe opening degree is preset for the first regulating valve. Variables in the formula represent only numerical values and do not contain units.

According to the formula, the target opening degree of the first regulating valve can be calculated, and the target opening degree of the first regulating valve corresponds to the target opening degree of the first regulating valve in proportion according to a preset relation. For example, the target opening degree is 10, and the corresponding target opening degree proportion is 10%, that is, the target opening degree is 10% of the total opening degree. Alternatively, the target opening degree is 50, and the corresponding target opening degree proportion is 10%, that is, the target opening degree is 10% of the total opening degree. Of course, the correspondence relationship between the target opening degree and the opening degree ratio may be other, and the above example is only for ease of understanding. The specific value of α can be adjusted to a number between (0, 1) depending on the test. For example, α may be 0.3, 0.4, 0.5, 0.6, or 0.7. Y is_pThe specific value of (c) can be adjusted to a number between (0, 10) according to the test. For example, Y_pAnd may be 3, 4, 5, 6 or 7. Therefore, the target opening degree of the first regulating valve can be accurately regulated, and the dehumidification efficiency is improved.

Optionally, the processor determines a difference between the current temperature and the historical temperature of the coil, including: the third temperature sensor detects an outdoor ambient temperature. The processor determines a temperature correction value based on the outdoor ambient temperature. The processor determines the difference between the current temperature and the historical temperature of the coil as the difference between the current temperature and the historical temperature of the coil, and the sum of the temperature correction values. Thus, the processor corrects the current temperature of the coil, and the dehumidification effect can be improved when the indoor environment temperature is low.

Optionally, processor rootAccording to the temperature difference value of the coil pipe and the current opening degree of the first regulating valve, determining the target opening degree of the first regulating valve, wherein the method comprises the following steps: y is_n＝Y_n-1+|△T+T_c|×Y_p+(△T+T_c)×α×Y_p. Wherein, T ═ T_n-T_n-1，Y_nIs a target opening degree of the first regulating valve, Y_n-1Is the current opening of the first regulating valve, T_nIs the current temperature of the coil, T_n-1The historical temperature of the coil, delta T is the temperature difference of the coil, alpha is the opening correction coefficient, Y_pFor a preset regulating opening, T, of the first regulating valve_cIs a temperature correction value. Variables in the formula represent only numerical values and do not contain units.

The correspondence between the outdoor ambient temperature and the temperature correction value is shown in table 1:

And S342, the processor adjusts the running speed of the first fan by using the first fan speed correction value.

Like this, according to outdoor ambient temperature, select corresponding first fan rotational speed, can slow down the speed that indoor ambient temperature descends. The higher the indoor environment humidity is, the higher the first fan rotation speed is required for dehumidification. According to the indoor environment humidity, the rotating speed of the first fan is corrected, and the dehumidification speed can be further improved.

TABLE 3

Optionally, the processor in step S342 adjusts the operating speed of the first fan by using the first fan speed correction value, and superimposes the first fan speed correction value on the basis of the operating speed of the first fan. Therefore, under the condition that the indoor environment humidity is high, the rotating speed of the first fan is increased, and the dehumidifying speed can be increased.

And S270, determining the opening proportion of the second regulating valve corresponding to the outdoor environment temperature by the processor according to the outdoor environment temperature.

And S351, determining a second regulating valve opening ratio correction value corresponding to the indoor environment humidity by the processor according to the indoor environment humidity.

And S352, the processor adjusts the opening ratio of the second regulating valve by using the second regulating valve opening ratio correction value.

In this way, the opening ratio of the second regulating valve is selected according to the outdoor ambient temperature, and the speed of the drop of the indoor ambient temperature can be reduced. Since the higher the indoor ambient humidity is, the higher the opening ratio of the second regulating valve required for air circulation is. According to the indoor environment humidity, the opening ratio of the second regulating valve is corrected, so that the second evaporator can assist the first evaporator in dehumidifying.

And the opening proportion of the second regulating valve is the ratio of the opening of the second regulating valve to the total opening.

The corresponding relationship between the outdoor ambient temperature and the opening ratio of the second regulating valve is shown in table 4:

TABLE 4

The correspondence relationship between the indoor ambient humidity and the second adjustment valve opening degree ratio correction value is shown in table 5:

TABLE 5

Alternatively, the processor in step S352 adjusts the opening ratio of the second regulating valve using the second regulating-valve-opening-ratio correction value by superimposing the second regulating-valve-opening-ratio correction value on the opening ratio of the second regulating valve. Thus, when the indoor environment humidity is high, the opening degree of the second regulating valve is increased, and the dehumidification speed can be increased.

Referring to fig. 7, another method for dehumidifying an air conditioner according to an embodiment of the present disclosure includes:

And S290, determining the rotating speed of the second fan corresponding to the outdoor environment temperature by the processor according to the outdoor environment temperature.

And S361, the processor determines a second fan rotating speed correction value corresponding to the indoor environment humidity according to the indoor environment humidity.

And S362, adjusting the running speed of the second fan by the processor by using the second fan speed correction value.

Therefore, according to the outdoor environment temperature, the corresponding rotating speed of the second fan is selected, and the speed of reducing the indoor environment temperature can be reduced. Since the higher the indoor ambient humidity is, the higher the second fan rotational speed required for air circulation is. According to indoor ambient humidity, revise the second fan rotational speed, can improve the efficiency of dehumidification.

The corresponding relationship between the outdoor environment temperature and the second fan rotation speed is shown in table 6:

TABLE 6

The corresponding relationship between the indoor ambient humidity and the second fan rotation speed correction value is shown in table 7:

TABLE 7

Optionally, the processor in step S362 adjusts the operating speed of the second fan by using the second fan speed correction value, and superimposes the second fan speed correction value on the basis of the operating speed of the second fan. Therefore, under the condition that the indoor environment humidity is high, the rotating speed of the second fan is increased, and the dehumidifying speed can be increased.

Thus, the corresponding compressor frequency is selected according to the outdoor environment temperature, so that the efficiency of dehumidification can be improved, and the indoor environment temperature can be prevented from being reduced too fast. The frequency of the compressor is corrected according to the indoor environment humidity, and the dehumidification efficiency can be improved.

The correspondence between the outdoor ambient temperature and the compressor frequency is shown in table 8:

TABLE 8

The correspondence between the indoor ambient humidity and the compressor frequency correction value is shown in table 9:

TABLE 9

Optionally, the processor in step S372 adjusts the operating frequency of the compressor by using the compressor frequency correction value, and the compressor frequency correction value is superimposed on the operating frequency of the compressor.
