Referring to fig. 1, an embodiment of the present disclosure provides a control method for dehumidification of an air conditioner, including:
and step S01, acquiring the ambient temperature and the set temperature in the dehumidification mode.
In an embodiment, when a user sets the air conditioner to the dehumidification mode, it is generally aimed to perform humidity adjustment of an indoor environment using the air conditioner. However, when the air conditioner adjusts the humidity, the indoor environment temperature is often adjusted synchronously, and at this time, the acquired indoor environment temperature is used for further setting the air conditioner in the dehumidification mode, so as to adjust the indoor environment temperature in the dehumidification mode. Embodiments of the present disclosure thus provide a control method for dehumidification of an air conditioner that is a control flow enabled when the air conditioner is operating in a dehumidification mode.
And S02, controlling the compressor to operate according to the initial frequency when the difference value between the ambient temperature and the set temperature meets a first condition, and setting the operating frequency of the compressor according to the temperature of the inner coil.
The intelligent control of the air conditioner is realized by setting the difference relation between the ambient temperature and the set temperature, and when the indoor ambient temperature where a user is located has a certain difference with the set temperature, the frequency of the compressor is controlled to compensate the current ambient temperature.
Different humidity thresholds may be selected for the first condition according to different seasons, temperatures, or weather conditions. According to different indoor temperature conditions, the incidence relation between the indoor environment temperature and the first condition can be preset in an electric control board of the air conditioner, so that the first condition corresponding to the temperature can be called when the indoor environment is at a certain temperature, the intelligent control of the air conditioner is realized, the indoor environment where a user is located can reach the optimal temperature and humidity conditions, and the problem of air supercooling caused by excessive dehumidification is prevented.
The initial frequency of the compressor is a value lower than the maximum operation frequency of the compressor in the dehumidification mode. In this embodiment, the initial frequency is assigned to 50Hz, and the maximum operation frequency of the compressor in the dehumidification mode is assigned to 65Hz. In other embodiments of the present disclosure, the initial frequency may also be determined according to one or more of an ambient temperature, an ambient humidity, a target temperature, and a target humidity of the air conditioner.
By adopting the control method for air conditioner dehumidification provided by the embodiment of the disclosure, the frequency of the compressor is periodically corrected according to the temperature of the inner coil pipe while dehumidification is carried out. Therefore, when the indoor room dehumidification requirement is met, the compressor frequency is accurately controlled, stable adjustment of indoor air is achieved, and the use comfort of a user is improved.
Optionally, setting the operating frequency of the compressor according to the temperature of the inner coil comprises: periodically acquiring the current temperature of the inner coil; and setting the running frequency of the compressor according to the difference value between the current temperature of the inner coil and the target temperature of the inner coil.
The detection period for acquiring the temperature of the coil pipe in the air conditioner can be 30 seconds, 60 seconds and 120 seconds, and can also be set according to the ambient temperature. The incidence relation between the indoor environment temperature and the detection period can be preset in an electric control board of the air conditioner, so that when the indoor environment is at a certain temperature, the current temperature of the inner coil can be obtained regularly to correct the frequency of the compressor, and the intelligent control of the air conditioner is realized. In this embodiment, the detection period is set to 30 seconds to achieve accurate regulation of the compressor frequency.
Alternatively, the greater the difference between the current inner coil temperature and the target inner coil temperature, the higher the operating frequency of the compressor.
The ambient temperature drops in the indoor dehumidification process of air conditioner, and the condition that ambient humidity rises, interior coil pipe temperature also can change. When the difference between the temperature of the inner coil and the temperature of the target inner coil is large, the running frequency of the compressor is increased to increase the circulation amount of the refrigerant, the rise of the ambient temperature can be realized, and the temperature is prevented from continuously falling to influence the comfort level of a user.
Optionally, setting an operating frequency of the compressor according to a difference between the current inner coil temperature and the target inner coil temperature, including: determining a temperature interval in which the difference value between the current temperature of the inner coil and the target temperature of the inner coil is located; and determining a compressor running frequency correction value corresponding to the temperature interval according to the preset corresponding relation, and correcting the current running frequency.
For example, when the difference value between the current inner coil temperature and the target inner coil temperature is greater than a first set temperature, the operating frequency correction value of the compressor is a first correction value, and the current operating frequency of the compressor is controlled to be increased by the first correction value; and when the difference value between the current inner coil temperature and the target inner coil temperature is less than or equal to the first set temperature, the operating frequency correction value of the compressor is a second correction value, and the current operating frequency of the compressor is controlled to be increased by the second correction value. Wherein the first correction value is greater than the second correction value.
Specifically, the current inner coil temperature and the target inner coil temperature are obtained, the difference value of the current inner coil temperature and the target inner coil temperature is calculated, and when the difference value is larger than or equal to 3, the first correction value is 3Hz; when the temperature interval of the difference is (1,3), the second correction value is 2Hz; when the temperature range of the difference is [ -1,1], the third correction value is 0Hz; and when the difference is smaller than-1, the fourth correction value is-2 Hz. And correcting the current running frequency according to the correction value, and controlling the compressor to execute the corrected frequency value.
Here, a corresponding relationship between a temperature interval of a difference between a current inner coil temperature and a target inner coil temperature and a compressor operation frequency correction value is preset in the air conditioner. The larger the maximum critical value of the temperature interval is, the larger the value of the corresponding compressor operation frequency correction value is.
Therefore, after the compressor is controlled to execute the operating frequency in the dehumidification mode in the embodiment of the disclosure, the operating frequency of the compressor is further corrected according to the corresponding relation between the temperature of the inner coil and the operating frequency correction value of the compressor, so that the air conditioner can operate stably while the temperature is rapidly raised, and the phenomenon that the protection is caused due to the too fast temperature rise and the system operation is not facilitated is avoided.
Alternatively, in the case of increasing the compressor frequency, when coil temperature freeze protection is present, increasing the compressor frequency is stopped.
Alternatively, in the case of increasing the compressor frequency, when the corrected compressor frequency value is higher than the maximum operating frequency of the compressor in the dehumidification mode, the compressor is controlled to operate at the maximum operating frequency of the compressor in the dehumidification mode.
Optionally, in the case of reducing the frequency of the compressor, when the difference between the acquired coil temperature and the current dew point temperature is less than the second threshold value, the reduction of the frequency of the compressor is stopped. At this moment, the temperature of the coil pipe is low, and the indoor environment temperature is easily too low due to the fact that the frequency of the compressor is continuously reduced, so that the use comfort of a user is affected.
Alternatively, in the case of reducing the compressor frequency, when the corrected compressor frequency value is lower than the minimum operating frequency of the compressor in the dehumidification mode, the compressor is controlled to operate at the minimum operating frequency of the compressor in the dehumidification mode.
Optionally, the target inner coil temperature is set according to a dew point temperature. Specifically, the target temperature of the inner coil is determined according to the following manner:
T ps ＝k×T d +a (1)
wherein, T ps Is the target temperature of the inner coil, T d The current dew point temperature is a correction coefficient, and k is a weighted value larger than 0.
Alternatively, the correction coefficient may be a constant or a variable value determined according to the ambient temperature, the relative humidity, and the like. Therefore, the temperature of the inner coil can be adjusted in real time according to the current dew point temperature according to the formula (1) so as to compensate and adjust the current environment temperature. The higher the current dew point temperature, the higher the target temperature of the inner coil of the air conditioner.
Optionally, the value of the weighted value k is related to an operation mode of the air conditioner before the air conditioner receives the dehumidification instruction. Different values are set for the weighting value k according to different working modes. Optionally, the value of the weighting value k is related to the change speed of the indoor environment temperature. The faster the change speed of the indoor ambient temperature is, the smaller the value of the weighted value k is.
Optionally, setting the target inner coil temperature according to the dew point temperature comprises: acquiring the current dew point temperature of the air conditioner as the target temperature of the inner coil; periodically obtaining the difference value between the current dew point temperature and the target dew point temperature, and determining a correction coefficient; and correcting the target temperature of the inner coil according to the correction coefficient. Here, the value of the target dew point temperature is related to the target ambient temperature and the target humidity. During dehumidification, the ambient temperature decreases and the ambient humidity increases, so that the value of the obtained current dew point temperature also changes. Here, the dew point temperature is a temperature at which water vapor and water in the air reach an equilibrium state, and a value thereof may be obtained by a dew point meter, or may be obtained by an ambient temperature and a relative humidity.
Optionally, the larger the difference between the current dew point temperature and the set dew point temperature is, the smaller the value of the correction coefficient is.
Optionally, determining the correction factor according to the difference between the current dew point temperature and the set dew point temperature includes: determining a temperature interval according to the difference value between the current dew point temperature and the set dew point temperature; and determining correction parameters corresponding to the temperature intervals according to the preset corresponding relation.
For example, when the difference between the current dew point temperature and the set dew point temperature is greater than or equal to 3, the correction parameter is a first correction parameter, and the target temperature of the inner coil is controlled to be increased by the first correction parameter on the basis of an initial value determined according to the current dew point temperature. When the difference value between the current dew point temperature and the set dew point temperature is in the temperature interval of (1,3), the correction parameter is a second correction parameter, and at the moment, the target temperature of the inner coil is controlled to be increased by the second correction parameter on the basis of the initial value determined according to the current dew point temperature. When the difference value between the current dew point temperature and the set dew point temperature is in the temperature range of [ -1,1], the correction parameter is a third correction parameter, and at the moment, the target temperature of the inner coil is controlled to be increased by the third correction parameter on the basis of the initial value determined according to the current dew point temperature. And when the difference value between the current dew point temperature and the set dew point temperature is less than-1, the correction parameter is a fourth correction parameter, and the fourth correction parameter is added on the basis of controlling the target temperature of the inner coil according to the initial value determined by the current dew point temperature. The first correction parameter, the second correction parameter, the third correction parameter and the fourth correction parameter are increased in sequence. Optionally, the first modification parameter is assigned a value of-3, the second modification parameter is assigned a value of-1, the third modification parameter is assigned a value of 0, and the fourth modification parameter is assigned a value of 1.
Optionally, the current dew point temperature in the above embodiment is obtained by the ambient temperature and the relative humidity.
Specifically, the current dew point temperature is obtained by:
T d ＝a+b×T r +c×Rh (2)
wherein, T d Is the current dew point temperature, T r Rh is the relative humidity, and a, b, c are weights greater than 0 for the ambient temperature.
Thus, the current dew point temperature can be estimated from the ambient temperature and the relative humidity according to equation (2). The higher the ambient temperature, the higher the current dew point temperature; the higher the relative humidity, the higher the current dew point temperature. It should be noted that in the calculation of equation (2), T is performed r And performing algebraic evaluation on the Rh numerical value without unit conversion.
Optionally, the values of the weighted values b and c are related to the working mode of the air conditioner before the air conditioner receives the dehumidification instruction. And setting different values for the weighted values b and c according to different working modes. Optionally, the value of the weighting value a is related to the change speed of the indoor environment temperature. The faster the indoor ambient temperature changes, the smaller the value of the weighted value a.
Here, the set dew point temperature value is related to the target ambient temperature and the target humidity. During dehumidification, the ambient temperature decreases and the ambient humidity increases, so that the value of the obtained current dew point temperature also changes.
By adopting the control method for air conditioner dehumidification provided by the embodiment of the disclosure, the frequency of the compressor is periodically corrected according to the temperature of the inner coil pipe while dehumidification is carried out. Therefore, when the indoor room dehumidification requirement is met, the compressor frequency is accurately controlled, stable adjustment of indoor air is achieved, and the use comfort of a user is improved.
Referring to fig. 2, a control method for dehumidification of an air conditioner according to an embodiment of the present disclosure includes:
and S10, entering a dehumidification mode according to the instruction, controlling the frequency of the compressor to operate at the maximum operation frequency in the dehumidification mode, and adjusting the indoor fan to operate at a low wind speed. Here, the compressor frequency is controlled to run at 65Hz.
In step S11, the ambient temperature Tr and the set temperature Ts are acquired.
Step S12, when-1<T r -T s <And 3, performing PID control on the inner coil, and controlling the target temperature Tps =12 ℃ of the inner coil.
And S13, detecting the current inner coil temperature Tp in real time, and periodically calculating the difference value between the current inner coil temperature Tp and the target temperature Tps of the target inner coil, namely the inner coil temperature deviation c. Here, the calculation period is set to 30 seconds.
And S14, determining a corrected value of the running frequency of the compressor according to the temperature deviation c of the inner coil, correcting the current running frequency of the compressor, and controlling the compressor to execute the corrected running frequency. Specifically, when the ce is more than or equal to 3, the corrected value of the running frequency of the compressor is 3Hz; when 1< -c < -3 > s, the operating frequency correction value of the compressor is 2Hz; when e is more than or equal to-1 and less than or equal to 1, the running frequency correction value of the compressor is 0; when the dew point deviation e < -1, the corrected value of the running frequency of the compressor is-2 Hz. It should be noted that after the temperature deviation c of the inner coil is periodically obtained and the operating frequency correction value of the compressor is determined according to the value, the operation frequency is corrected on the basis of the frequency of the compressor after the previous correction, so that the frequency of the compressor is controlled to be increased or decreased according to the temperature of the inner coil.
Step S14 also comprises that in the case of increasing the frequency of the compressor, when the coil temperature anti-freezing protection is occurred, the increase of the frequency of the compressor is stopped; and when the corrected compressor frequency value is higher than the maximum operation frequency of the compressor in the dehumidification mode, controlling the compressor to operate at the maximum operation frequency of the compressor in the dehumidification mode. Under the condition of reducing the frequency of the compressor, when the difference value between the acquired coil temperature and the current dew point temperature is smaller than a second threshold value, stopping reducing the frequency of the compressor; and when the corrected compressor frequency value is lower than the minimum operation frequency of the compressor in the dehumidification mode, controlling the compressor to operate at the minimum operation frequency of the compressor in the dehumidification mode.
Referring to fig. 3, an embodiment of the present disclosure provides a control apparatus for dehumidification of an air conditioner, including a detection module 21 and a control module 22. The detection module 21 is configured to obtain an ambient temperature and a set temperature in the dehumidification mode; the control module 22 is configured to control the compressor to operate at an initial frequency and set an operating frequency of the compressor based on the inner coil temperature when the difference between the ambient temperature and the set temperature satisfies a first condition.
By adopting the control device for air conditioner dehumidification provided by the embodiment of the disclosure, the frequency of the compressor is periodically corrected according to the temperature of the inner coil pipe while dehumidification is carried out. Therefore, when the indoor room dehumidification requirement is met, the compressor frequency is accurately controlled, stable adjustment of indoor air is achieved, and the use comfort of a user is improved.
