Optionally, the air conditioner controls the air conditioner to operate in a dehumidification mode after the dehumidification function is started. At this time, the air conditioner can further regulate and control the indoor temperature besides performing indoor dehumidification, that is, the indoor temperature can be controlled to approach the set temperature (for example, the indoor temperature is controlled to be equal to the set temperature, or the indoor temperature is controlled to be within a preset deviation range of the set temperature, and the preset deviation range can be the set temperature +/-0-2 ℃) while reducing the indoor humidity. Accordingly, the dehumidification mode may be a constant temperature dehumidification mode.
Alternatively, the air conditioner may acquire the current indoor humidity in the air conditioner active space through a humidity sensor.
And S30, when the current indoor humidity is higher than the set humidity, adjusting the evaporation temperature of the evaporator of the air conditioner to be lower than the dew point temperature.
And S40, when the current indoor humidity is less than the set humidity, adjusting the evaporation temperature of the evaporator of the air conditioner to be greater than the dew point temperature.
Optionally, the terminal obtains the set humidity of the air conditioner, and adjusts the evaporation temperature of the evaporator of the air conditioner according to the current indoor humidity and the set humidity. The set humidity can be set by a user, or the set humidity can be humidity which is obtained by the terminal according to the weather and the outdoor humidity of the current time and is suitable for a human body based on a big data algorithm.
Optionally, when the terminal detects that the current indoor humidity is greater than the set humidity, the operating frequency of the compressor of the air conditioner is increased to reduce the evaporation temperature of the evaporator of the air conditioner until the evaporation temperature is less than the dew point temperature of the current time, that is, when the current indoor humidity is greater than the set humidity, the air conditioner is controlled to perform the step of adjusting the evaporation temperature to be less than the dew point temperature (which is equivalent to controlling the air conditioner to be in a mode in which the evaporation temperature is less than the dew point temperature).
Optionally, when the terminal detects that the current indoor humidity is less than the set humidity, the operating frequency of the compressor of the air conditioner is reduced to increase the evaporation temperature of the evaporator of the air conditioner until the evaporation temperature is greater than the dew point temperature of the current time, that is, when the current indoor humidity is less than the set humidity, the air conditioner is controlled to adjust that the evaporation temperature is greater than the dew point temperature (which is equivalent to controlling the air conditioner to be in a mode where the evaporation temperature is greater than the dew point temperature).
In one embodiment, the air conditioner is controlled to operate a dehumidification mode; acquiring current indoor humidity; when the current indoor humidity is higher than the set humidity, adjusting the evaporation temperature of an evaporator of the air conditioner to be lower than the dew point temperature; and when the current indoor humidity is smaller than the set humidity, adjusting the evaporation temperature of the evaporator of the air conditioner to be larger than the dew point temperature. Like this, realize when the air conditioner dehumidifies, avoid indoor temperature to hang down excessively, solved the air conditioner and can cause the problem that indoor ambient temperature hangs down when dehumidifying.
In a second embodiment, as shown in fig. 3, on the basis of the embodiment shown in fig. 2, after the step of controlling the air conditioner to operate in the dehumidification mode, the method further includes:
and S21, acquiring the current indoor temperature.
And S22, switching the operation modes of the air conditioner according to the current indoor temperature and the set temperature, wherein the operation modes comprise a cooling mode and a heating mode.
And S23, executing the step of acquiring the current indoor humidity when the air conditioner operates in the refrigeration mode.
In this embodiment, after the air conditioner operates in the dehumidification mode, the terminal may obtain the current indoor temperature in the air conditioner operating space through the temperature sensor. And the terminal can acquire the set temperature of the air conditioner.
Optionally, the terminal determines an operation mode of the air conditioner according to the current indoor temperature and the set temperature, wherein the operation mode includes a cooling mode and a heating mode. When the terminal detects that the current indoor temperature is lower than the set temperature, the air conditioner is controlled to operate in a heating mode; and when detecting that the current indoor temperature is higher than the set temperature, the terminal controls the air conditioner to operate in a refrigeration mode.
Therefore, after the constant temperature dehumidification function is started, the terminal can control the air conditioner to switch between the refrigeration mode and the heating mode according to the current indoor temperature and the set temperature. And when the temperature is too low, the air conditioner is controlled to be switched to a heating mode to heat and output to improve the indoor temperature, and after the indoor temperature is improved, the air conditioner is controlled to be switched back to a cooling mode to continue refrigerating and dehumidifying.
Optionally, in order to avoid frequent switching of the air conditioner between the cooling mode and the heating mode, a cooling temperature limit value and a heating temperature limit value may be preset, and the air conditioner may be controlled to switch to the heating mode when the current indoor temperature is lower than the cooling temperature limit value, and to switch to the cooling mode when the current indoor temperature is higher than the heating temperature limit value. Alternatively, the refrigeration temperature limit may be obtained by subtracting a preset temperature value from a set temperature; the refrigeration temperature limit value can be obtained by adding a preset temperature value to a set temperature; the preset temperature value can be in the range of 0-2 ℃ and can be selected as 0.5 ℃.
Optionally, in order to avoid frequent switching of the air conditioner between the cooling mode and the heating mode, after the air conditioner meets a condition of switching from the current operation mode to another operation mode, an operation duration corresponding to the current operation mode is obtained first, and when the operation duration is greater than a first preset duration, the air conditioner is controlled to switch to the another operation mode. The first preset time period may range from 3 minutes to 10 minutes, and may be 6 minutes.
Optionally, when the air conditioner is currently operated in a cooling mode, when the terminal detects that the current indoor temperature is less than a set temperature (or a cooling temperature limit value), acquiring the operation duration of the air conditioner in the cooling mode, and when the terminal detects that the operation duration corresponding to the cooling mode is greater than a first preset duration, controlling the air conditioner to switch to the heating mode; and when the terminal detects that the operation duration of the cooling mode is less than or equal to the first preset duration, the air conditioner is still not controlled to be switched from the cooling mode to the heating mode even if the current indoor temperature is detected to be less than the set temperature.
Optionally, when the air conditioner operates in the heating mode currently, when the terminal detects that the current indoor temperature is greater than the set temperature (or the heating temperature limit value), acquiring the operation duration of the air conditioner operating in the heating mode currently, and when detecting that the operation duration corresponding to the heating mode is greater than a first preset duration, controlling the air conditioner to switch to the cooling mode; and when the terminal detects that the operation duration of the heating mode is less than or equal to the first preset duration, the air conditioner is still not controlled to be switched from the heating mode to the cooling mode even if the current indoor temperature is detected to be greater than the set temperature.
Optionally, when the air conditioner operates in a cooling mode, the current indoor humidity is obtained, and the evaporation temperature of an evaporator of the air conditioner is adjusted according to the current indoor humidity and the set humidity, wherein the current indoor humidity is greater than the set humidity, the evaporation temperature is less than the dew point temperature, the current indoor humidity is less than the set humidity, and the evaporation temperature is greater than the dew point temperature.
Optionally, the terminal controls the air conditioner to repeatedly execute the steps until the indoor temperature is within the preset deviation range of the set temperature and the outdoor humidity is within the preset humidity deviation range of the set humidity, and then the air conditioner closes the constant temperature dehumidification function and recovers the operation mode and the operation parameters before the constant temperature dehumidification function is started. The preset deviation range can be the set temperature +/-0-2 ℃, and the deviation range of the preset time period can be the set humidity +/-0-10%.
In one embodiment, a current indoor temperature is obtained; switching operation modes of the air conditioner according to the current indoor temperature and the set temperature, wherein the operation modes comprise a cooling mode and a heating mode; and the air conditioner operates in the refrigeration mode and executes the step of acquiring the current indoor humidity. Therefore, the air conditioner operates in a dehumidification mode, when the temperature is too low, the air conditioner is controlled to be switched to a heating mode to heat and output to increase the indoor temperature, and when the indoor temperature is increased, the air conditioner is controlled to be switched back to the cooling mode to continue cooling and dehumidifying, so that the problem that the indoor environment temperature is too low when the air conditioner dehumidifies is solved.
In a third embodiment, as shown in fig. 4, on the basis of the above embodiments of fig. 2 to 3, after the step of obtaining the current indoor temperature, the method further includes:
and S50, determining the difference between the current indoor temperature and the set temperature.
And S51, controlling the air conditioner to operate in a no-wind-sense mode when the difference value is smaller than a preset value.
In this embodiment, after the air conditioner operates in the dehumidification mode, the terminal may obtain the current indoor temperature in the air conditioner operating space through the temperature sensor. And the terminal can acquire the set temperature of the air conditioner.
Alternatively, the terminal may calculate a difference between the current indoor temperature and the set temperature (the current indoor temperature minus the set temperature), and compare the calculated difference with a preset value. The value range of the preset value can be selected from 1-5 ℃, and can be selected from 4 ℃.
Optionally, when detecting that the calculated difference is greater than or equal to a preset value, the terminal controls the air conditioner to operate in a set air mode or an automatic air mode.
Optionally, no matter whether the air conditioner operates in a cooling mode or a heating mode currently, when the terminal detects that the calculated difference is smaller than a preset value, the air conditioner is controlled to operate in a no-wind-sense mode at the same time.
It should be noted that, the air deflector of the air conditioner with non-wind-sensing air supply is provided with the air-permeable micropores, and when the air conditioner enters the non-wind-sensing air supply mode, the air deflector is controlled to be closed (for example, the air supply angle of the air deflector is adjusted to be 0 °), so that the air conditioner exhausts air through the air-permeable pores on the air deflector.
Like this, for preventing that the air conditioner is when refrigeration mode and heating mode constantly switch, because of going out cold wind for a moment, go out hot-blast for a moment, and cause human travelling comfort relatively poor, at present indoor temperature and set for the difference between the temperature and be less than the default, control air conditioner is with the operation of non-wind sense mode, let the air current pass through the ventilative hole air-out and see through, avoid the human body to experience cold and hot wind in turn to under the prerequisite of guaranteeing the comfort level, indoor temperature and humidity reach the target simultaneously and set for the scope.
In a fourth embodiment, as shown in fig. 5, on the basis of the above embodiments of fig. 2 to 4, after the step of switching the operation mode of the air conditioner according to the current indoor temperature and the set temperature, the method further includes:
and S40, operating the air conditioner in the refrigeration mode, and starting the electric auxiliary heating function of the air conditioner.
In this embodiment, the air conditioner is provided with an electric auxiliary heating mode, that is, the air conditioner has an electric auxiliary heating function.
The electric auxiliary heating function refers to a PTC electric auxiliary heating technology of the air conditioner. It is theorized that additional electrical heating increases the amount of heating. PTC is a semiconductor heating ceramic, and when the external temperature is lowered, the resistance value of PTC is reduced, and the heating value is increased accordingly. According to the principle, the air conditioner adopting the PTC electric auxiliary heating technology can automatically change the heating quantity according to the change of the room temperature and the air quantity of the indoor unit, thereby properly adjusting the room temperature and achieving the purpose of rapid and powerful heating.
Optionally, when the air conditioner ran in dehumidification mode, and the air conditioner ran in the refrigeration mode and refrigerates the dehumidification, in order to avoid the indoor temperature to hang down excessively (avoid the indoor temperature to descend too fast promptly), the terminal can control the air conditioner and open electric auxiliary heating function, adds through the electric auxiliary and challenges the certain heat of output to reduce the rate of indoor temperature cooling or promote the indoor temperature.
Optionally, the terminal may control the air conditioner to start the electric auxiliary heating function when the air conditioner operates in a dehumidification mode, and when the air conditioner operates in a refrigeration mode to perform refrigeration and dehumidification and detects that the current indoor temperature is lower than a preset temperature. Wherein the preset temperature is less than or equal to the set temperature of the air conditioner. It should be noted that the actual value of the preset temperature can be set by an engineer according to actual needs.
Optionally, when the air conditioner operates in the cooling mode and performs cooling and dehumidification, the terminal may calculate a difference between the current indoor temperature and the set temperature (the current indoor temperature minus the set temperature), and compare the calculated difference with a preset value. The value range of the preset value can be selected from 1-5 ℃, and can be selected from 4 ℃. Further, when the terminal detects that the calculated difference value is larger than or equal to a preset value, the air conditioner is controlled to start the electric auxiliary heating function.
Therefore, the problem that the user feels uncomfortable due to the fact that the ambient temperature is too low when the air conditioner dehumidifies is solved.
In a fifth embodiment, as shown in fig. 6, on the basis of the above embodiments of fig. 2 to 5, after the step of adjusting the evaporation temperature of the evaporator of the air conditioner to be less than the dew point temperature, the method further includes:
and S31, acquiring a first duration of the evaporation temperature being less than the dew point temperature.
And S32, when the first duration is longer than a second preset duration, adjusting the evaporation temperature to be larger than the dew point temperature.
In this embodiment, in order to avoid frequently increasing or decreasing the evaporation temperature of the air conditioner, that is, to avoid the air conditioner frequently performing two steps of the step of adjusting the evaporation temperature to be greater than the dew point temperature and the step of adjusting the evaporation temperature to be less than the dew point temperature (that is, to avoid the air conditioner from switching back and forth between two modes, that is, between a mode in which the evaporation temperature is less than the dew point temperature and a mode in which the evaporation temperature is greater than the dew point temperature), therefore, after the step of adjusting the evaporation temperature to be less than the dew point temperature is performed by the air conditioner (when the air conditioner is currently in the mode in which the evaporation temperature is less than the dew point temperature), when it is detected that the current indoor humidity is less than the set humidity, the step of adjusting the evaporation temperature to be less than the dew point temperature is obtained for a first duration (the first duration is equivalent to an operation duration of the air conditioner in the mode in which the evaporation temperature is less than the dew point temperature), and when the first duration is greater than a second preset duration, the step of adjusting the evaporation temperature to be greater than the dew point temperature is performed (that the air conditioner is switched to the mode in which the dew point temperature is greater than the dew point temperature is controlled by the first duration; and when the terminal detects that the first duration is less than or equal to the second preset duration, the mode that the evaporation temperature is less than the dew point temperature is not switched to the mode that the evaporation temperature is greater than the dew point temperature even if the current indoor humidity is detected to be less than the set humidity.
Optionally, the second preset time period may range from 3 minutes to 10 minutes, and may be optionally 6 minutes.
In a sixth embodiment, as shown in fig. 7, on the basis of the above embodiments of fig. 2 to 6, after the step of adjusting the evaporation temperature of the evaporator of the air conditioner to be greater than the dew point temperature, the method further includes:
and S41, acquiring a second duration of the evaporation temperature greater than the dew point temperature.
And S42, when the second duration is longer than a second preset duration, adjusting the evaporation temperature to be smaller than the dew point temperature.
In this embodiment, in order to avoid frequently increasing or decreasing the evaporation temperature of the air conditioner, after the air conditioner performs the step of adjusting the evaporation temperature to be greater than the dew point temperature (when the air conditioner is currently in a mode in which the evaporation temperature is greater than the dew point temperature), when it is detected that the current indoor humidity is greater than the set humidity, a second duration corresponding to the step of adjusting the evaporation temperature to be greater than the dew point temperature is obtained (the second duration is equal to an operation duration of the air conditioner in the mode in which the evaporation temperature is greater than the dew point temperature), and when the second duration is greater than a second preset duration, the step of adjusting the evaporation temperature to be less than the dew point temperature is performed (i.e., the air conditioner is controlled to switch to the mode in which the evaporation temperature is less than the dew point temperature); and when the terminal detects that the second duration is less than or equal to the second preset duration, the mode that the evaporation temperature is greater than the dew point temperature is not switched to the mode that the evaporation temperature is less than the dew point temperature even if the current indoor humidity is detected to be greater than the set humidity.
Optionally, the second preset time period may range from 3 minutes to 10 minutes, and may be optionally 6 minutes.
In addition, an embodiment of the present invention further provides an air conditioner, where the air conditioner includes a memory, a processor, and a control program of the air conditioner, where the control program of the air conditioner is stored in the memory and is executable on the processor, and the processor implements the steps of the control method of the air conditioner according to the above embodiment when executing the control program of the air conditioner.
