The embodiment of the invention provides a terminal related to a control method of an air conditioner. The hardware terminal related to the control method of the air conditioner can be a control terminal of the air conditioner and can also be the air conditioner.
In the embodiment of the present invention, referring to fig. 1, the terminal includes: a processor 1001 (e.g., a CPU), a timer 1002, a memory 1003, and the like. The memory 1003 may be a high-speed RAM memory or a non-volatile memory (e.g., a disk memory). The memory 1003 may alternatively be a storage device separate from the processor 1001.
Those skilled in the art will appreciate that the terminal structure shown in fig. 1 is not intended to be limiting and may include more or fewer components than those shown, or some components may be combined, or a different arrangement of components.
It is understood that, in an embodiment, a control program for implementing the control process of the air conditioner is stored in the memory 1003 of the terminal, and the processor 1001 may be configured to perform the following operations when calling the control program of the air conditioner stored in the memory 1003:

and controlling the air conditioner to operate according to the target evaporation temperature so as to reduce the fluctuation of the indoor environment humidity and the indoor environment temperature.
Various embodiments of the control method of the air conditioner of the present invention are proposed based on the hardware architecture of the above-mentioned terminal.
Referring to fig. 2, a first embodiment of a control method of an air conditioner according to the present invention is provided. In this embodiment, the method for controlling an air conditioner includes:
step S10, when the air conditioner meets the humidification condition, calculating the target dew point temperature according to the set humidity of the air conditioner and the indoor environment temperature of the air conditioner;
step S20, adjusting the target evaporation temperature according to the difference between the dew point temperature and the target evaporation temperature;
and step S30, controlling the air conditioner to operate according to the target evaporation temperature so as to reduce the fluctuation of the indoor environment humidity and the indoor environment temperature.
The embodiment of the present invention can be executed in an air conditioner, and can also be executed in a control terminal of the air conditioner.
Optionally, during the cooling process of the air conditioner, the indoor environment humidity may gradually decrease along with the cooling time. The humidity is too low and can influence indoor comfort, therefore, the air conditioner can carry out humidification under certain condition in the operation process, if slow down humidity reduction speed, perhaps start humidification mode etc.. In an optional embodiment, when a difference between the set humidity of the air conditioner and the indoor environment humidity of the air conditioner is greater than or equal to a second preset threshold, it is determined that the air conditioner satisfies the humidification condition, where the second preset threshold is a preset relative humidity threshold value that determines that the indoor environment humidity is lower.
Optionally, in another embodiment, when the air conditioner receives an instruction to turn on the humidification function in the cooling mode, it is determined that the air conditioner satisfies the humidification condition, or when the air conditioner enters the cooling mode from the humidification mode, it is determined that the air conditioner satisfies the humidification condition. Or when the difference value between the current indoor environment humidity and the indoor humidity before the preset time is larger than the preset humidity or the reduction rate of the current indoor environment humidity is larger than the preset reduction threshold value, judging that the air conditioner meets the humidification condition.
In this embodiment, in the air conditioner operation process, when the evaporating temperature of air conditioner is lower, indoor heat exchanger temperature is lower, when evaporating temperature is less than indoor ambient air's dew point temperature, the condensation phenomenon appears easily in indoor heat exchanger, and then the condition that the indoor environment humidity that the indoor set of air conditioner was located reduces fast appears easily.
Optionally, the target dew point temperature is an air dew point temperature corresponding to the indoor environment humidity where the indoor unit of the air conditioner is located when the indoor environment humidity is humidified to a set humidity, and the target dew point temperature may be determined in real time according to the current environment situation:
if the indoor environment temperature of the environment where the indoor unit of the air conditioner is located and the set humidity of the air conditioner are obtained; in one embodiment, a dew point temperature table is queried according to an indoor environment temperature and a set humidity, and the target dew point temperature is obtained; in another embodiment, the target dew point temperature is obtained by substituting the indoor environment temperature and the set environment temperature into a dew point calculation formula.
Optionally, the evaporation temperature corresponding to the set temperature may be a tube temperature of an indoor heat exchanger determined according to the set temperature, or a target temperature corresponding to a current operation mode, or an evaporation temperature determined according to an operation situation of the air conditioner, or determined according to a current environment requirement (at this time, the environment requirement only includes a refrigeration requirement) of an environment where the indoor unit is located, for example, an outdoor environment temperature where the air conditioner is located is obtained first, and the evaporation temperature corresponding to the set temperature is determined according to the set temperature, the outdoor environment temperature, and a difference between the indoor environment temperature and the set temperature.
Optionally, the target evaporation temperature may be a target temperature corresponding to the current operation mode, or a target evaporation temperature determined according to an operation situation of the air conditioner, or a target evaporation temperature determined according to a current environmental requirement of an environment in which the indoor unit is located, such as obtaining a target dew point temperature, a preset correction value, and an evaporation temperature corresponding to a set temperature.
It can be understood that, for a fixed target evaporation temperature, the target evaporation temperature is calculated in real time according to the current environmental requirement (the environmental requirement includes a humidity requirement and a temperature requirement) of the environment where the air conditioner is located in this embodiment, and the accuracy of controlling the indoor environmental temperature and the indoor environmental humidity where the indoor unit is located can be improved, so that the refrigeration effect and the humidification effect of the air conditioner can simultaneously meet the user requirement.
It can be understood that when the air conditioner is controlled to operate according to the target evaporation temperature, the temperature of the indoor environment where the air conditioner is located may change, and if the air conditioner is still controlled to operate according to the target evaporation temperature, the cooling effect is poor due to the high target evaporation temperature.
In one embodiment, after the step of controlling the operation of the air conditioner according to the target evaporation temperature, after the indoor environment temperature changes, the amplitude of the change of the indoor environment temperature is obtained, and when the amplitude is greater than or equal to a preset threshold value, the step of: the method comprises the steps of calculating a target dew point temperature according to set humidity of an air conditioner and indoor environment temperature where the air conditioner is located, further determining the target evaporation temperature of the air conditioner according to the target dew point temperature, a preset correction value and evaporation temperature corresponding to the set temperature, so that the indoor environment temperature and the indoor environment humidity are monitored in real time, the target dew point temperature is determined again when the indoor environment temperature changes and the change amplitude is large, the target evaporation temperature is further determined according to real-time environment requirements, and therefore the refrigeration effect and the humidification effect of the air conditioner are always attached to user requirements.
In another embodiment, at preset time intervals, a target dew point temperature is calculated according to the set humidity of the air conditioner and the indoor environment temperature of the air conditioner, and further, the target evaporation temperature of the air conditioner is determined according to the target dew point temperature, a preset correction value and the evaporation temperature corresponding to the set temperature.
In another embodiment, the dew point temperature of the environment where the indoor unit of the air conditioner is located and the target evaporation temperature of the air conditioner are obtained, and when the indoor environment temperature is detected to be changed and/or the set humidity is detected to be changed, the method returns to the execution step: the method comprises the steps of calculating a target dew point temperature according to the set humidity of the air conditioner and the indoor environment temperature where the air conditioner is located, further determining the target evaporation temperature of the air conditioner according to the target dew point temperature, a preset correction value and the evaporation temperature corresponding to the set temperature, and only re-determining the target evaporation temperature when the parameters change in the embodiment, so that the air conditioner is more energy-saving.
So, when indoor ambient temperature and/or set for humidity and/or set for the temperature and change, calculate target dew point temperature many times, and then confirm target evaporating temperature many times to the realization carries out real time monitoring to user's demand and indoor environment condition, and then makes the refrigeration effect and the humidification effect of air conditioner satisfy user's demand simultaneously.
In the embodiment, in the operation process of the air conditioner, when the air conditioner meets the humidification condition, the target evaporation temperature of the air conditioner is determined according to the target dew point temperature, the preset correction value and the evaporation temperature corresponding to the set temperature, and thus the evaporation temperature is corrected through the target dew point temperature and the preset correction value to obtain the target evaporation temperature. Because the target evaporating temperature is obtained by correcting the evaporating temperature based on the target dew point temperature and the preset correction value, the air conditioner operates in the process according to the target evaporating temperature, air condensation can be reduced to the maximum extent, further, the humidity is prevented from being reduced too low, and correction is performed on the basis of the evaporating temperature corresponding to the set temperature, so that the influence on the refrigerating effect is prevented from being too large, the refrigerating effect and the humidifying effect of the air conditioner are balanced, the fluctuation of the indoor environment humidity and the indoor environment temperature is reduced, the rapid reduction of the indoor environment humidity and the indoor environment temperature is avoided, and further, the refrigerating effect and the humidifying effect of the air conditioner simultaneously meet the user requirements.

Optionally, in some embodiments, when the air conditioner just starts the cooling mode, at this time, the indoor environment temperature is higher, the indoor environment humidity is higher, the situation that the indoor environment humidity is greater than or equal to the set humidity is likely to occur, and the evaporation temperature corresponding to the set temperature is lower, so that the evaporation temperature is increased by a proper amount to obtain the target evaporation temperature, and the air conditioner is controlled to operate according to the target evaporation temperature to reduce air condensation, thereby avoiding causing a rapid decrease in the indoor environment humidity after the air conditioner starts the cooling mode for a period of time.
Optionally, in other embodiments, during the operation of the air conditioner in the cooling mode, a situation that the indoor environment temperature is relatively moderate and the indoor environment humidity is relatively high may occur, at this time, the indoor environment humidity is greater than the set high humidity, and the evaporation temperature corresponding to the set humidity is relatively high or moderate, that is, the humidification effect of the air conditioner has met the user demand, so that the evaporation temperature is kept unchanged, thereby ensuring the cooling effect of the air conditioner to balance the cooling effect and the humidification effect of the air conditioner.
Optionally, in still other embodiments, after the air conditioner operates in the cooling mode for a period of time, at this time, the indoor environment temperature is low, the indoor environment humidity is low, a situation that the indoor environment humidity is less than the set humidity is likely to occur, the evaporation temperature corresponding to the set temperature is low, that is, the cooling effect of the air conditioner exceeds the user requirement, so that the evaporation temperature is increased to obtain the target evaporation temperature, and the air conditioner is controlled to operate according to the target evaporation temperature, thereby preventing the cooling effect of the air conditioner from exceeding the user requirement and the humidification effect from not meeting the user requirement.
Optionally, in still some embodiments, after the air conditioner operates in the cooling mode for a period of time, a situation that the indoor environment temperature is higher and the indoor environment humidity is lower may occur, at this time, the indoor environment humidity is smaller than the set humidity, and the difference between the calculated target dew point temperature and the evaporation temperature corresponding to the set humidity is not large, which indicates that the evaporation temperature corresponding to the set humidity is higher or moderate, and at this time, condensation generated on the surface of the indoor heat exchanger is less, that is, the humidification effect of the air conditioner after operating at the evaporation temperature for a period of time may meet the user demand, so that the evaporation temperature is kept unchanged, thereby ensuring the cooling effect of the air conditioner.
Optionally, in an embodiment, the indoor environment humidity where the air conditioner is located is obtained, when the indoor environment humidity is greater than or equal to a set humidity, the target evaporation temperature of the air conditioner is determined according to a difference value between the target dew point temperature and a preset correction value and the evaporation temperature corresponding to the set temperature, and when the indoor environment humidity is less than the set humidity, the target evaporation temperature of the air conditioner is determined according to a sum value of the target dew point temperature and the preset correction value and the evaporation temperature corresponding to the set temperature.
Optionally, in another embodiment, the indoor environment humidity where the air conditioner is located is obtained, when the indoor environment humidity is greater than or equal to the set humidity, the target evaporation temperature of the air conditioner is determined according to the sum of the target dew point temperature and the first correction value and the evaporation temperature corresponding to the set temperature, and when the indoor environment humidity is less than the set humidity, the target evaporation temperature of the air conditioner is determined according to the sum of the target dew point temperature and the second correction value and the evaporation temperature corresponding to the set temperature, wherein the first correction value is less than or equal to the second correction value.

If the indoor environment humidity is smaller than the set humidity, the indoor environment humidity is smaller, the target evaporation temperature of the air conditioner is determined according to the target dew point temperature, the sum of the preset correction value and the evaporation temperature corresponding to the set temperature, and the evaporation temperature is increased appropriately so as to improve the humidification effect of the air conditioner while ensuring the refrigeration effect of the air conditioner.
Alternatively, referring to fig. 4, a third embodiment of the control method for a multi-connected air conditioner is proposed based on the foregoing embodiment, and in this embodiment, step S23 includes:

if yes, executing step S233, taking the difference as the target evaporation temperature;
if not, step S234 is executed to set the evaporation temperature corresponding to the set temperature as the target evaporation temperature.
Alternatively, the preset correction value may be a fixed preset value, or may be determined according to the operating situation.
Optionally, in some embodiments, when the air conditioner starts to perform cooling, at this time, the indoor environment humidity is higher, the difference between the indoor environment humidity and the set humidity is larger, the larger the preset correction value is, the smaller the target evaporation temperature determined according to the preset correction value is, and during the cooling process of the air conditioner, the indoor environment humidity is reduced, and the difference between the indoor environment humidity and the set humidity is also reduced, at this time, if the air conditioner still operates at a lower target evaporation temperature, rapid reduction of the indoor environment humidity is easily caused, so that when the indoor environment humidity is lower, the preset correction value is determined according to the indoor environment temperature and the set temperature, when the indoor environment temperature is lower, the larger preset correction value is preset, and the target evaporation temperature determined according to the preset correction value is larger, so that when the indoor environment temperature meets the user requirement, the humidification effect is improved; when the indoor environment temperature is high, a small preset correction value is preset, the target evaporation temperature determined according to the preset correction value is small but is still larger than the evaporation temperature corresponding to the set temperature, and therefore the influence of humidification on the refrigeration effect is reduced.
In one embodiment, before obtaining the difference between the target dew point temperature and the preset correction value, the preset correction value is determined according to the indoor environment humidity and the set humidity, for example, when the set humidity is 55% and the indoor environment humidity is 60%, the preset correction value is 1; when the indoor ambient humidity is 65%, the preset correction value is 2.
In another embodiment, before obtaining the difference between the target dew-point temperature and the preset correction value, the preset correction value is determined by obtaining the indoor ambient humidity and the set humidity, and the preset correction value is adjusted according to the change value of the indoor ambient humidity, for example, when the set humidity is 55% and the indoor ambient humidity is 60%, the preset correction value is 1, and when the indoor ambient humidity is increased by 5%, the preset correction value is 2.
So, when indoor ambient humidity is great, confirm target evaporating temperature according to indoor ambient humidity with setting for humidity, when indoor ambient humidity is big more, it is big more to predetermine the corrective value this moment, and definite target evaporating temperature is little to can guarantee refrigeration effect, and when indoor ambient humidity reduces, reduce and predetermine the corrective value, and the target evaporating temperature of confirming increases, and target evaporating temperature is more than or equal to the evaporating temperature that the settlement temperature corresponds all the time, thereby can slow down indoor ambient humidity's quick reduction.
In this embodiment, a difference between the target dew point temperature and the preset correction value is obtained first, whether the difference is greater than or equal to the evaporation temperature corresponding to the set temperature is determined, when the difference is greater than or equal to the evaporation temperature corresponding to the set temperature, it is indicated that the evaporation temperature is too low at this time, and the difference is taken as the target evaporation temperature to appropriately increase the temperature of the indoor heat exchanger, so that a condensation phenomenon caused by too low temperature of the indoor heat exchanger in the following process is avoided, and thus rapid reduction of the indoor environment humidity is avoided.
Optionally, referring to fig. 5, a fourth embodiment of the control method for a multi-connected air conditioner is proposed based on the foregoing embodiment, and in this embodiment, step S24 includes:
when the environmental humidity is smaller than the set humidity, executing step S241 to obtain a sum of the target dew point temperature and the preset correction value;
step S242, determining whether the sum is greater than or equal to the evaporation temperature corresponding to the set temperature;
if yes, executing step S243 to use the sum as the target evaporation temperature;
if not, step S244 is executed to set the evaporation temperature corresponding to the set temperature as the target evaporation temperature.
In this embodiment, when indoor environment humidity is lower, through the temperature that improves target evaporating temperature in order to reduce indoor heat exchanger to reduce the condensation that appears on the indoor heat exchanger, and when target evaporating temperature was too high, lead to the refrigeration effect of air conditioner poor easily.
Alternatively, the preset correction value may be a fixed preset value, or may be determined according to the operating situation.
In one embodiment, the preset correction value is determined according to the indoor ambient temperature and the set temperature before the sum of the target dew point temperature and the preset correction value is obtained, for example, when the set temperature is 10 ℃, the indoor ambient temperature is 12 ℃, the preset correction value is 1, and when the indoor ambient temperature is 8 ℃, the preset correction value is 3.
In another embodiment, before the sum of the target dew-point temperature and the preset correction value is obtained, the preset correction value is determined according to the indoor environment temperature and the set temperature, and the preset correction value is adjusted according to the change value of the indoor environment humidity, for example, when the set temperature is 10 ℃, the indoor environment temperature is 12 ℃, the preset correction value is 1, and when the indoor environment temperature is reduced by 4 ℃, the preset correction value is 3.
Therefore, the preset correction value is determined according to the indoor environment temperature and the set temperature, when the indoor environment temperature is higher, the determined preset correction value is smaller, and the determined target evaporation temperature is lower, so that the refrigeration effect of the air conditioner can be ensured.
Furthermore, an embodiment of the present invention further provides a computer-readable storage medium, where a control program of an air conditioner is stored on the computer-readable storage medium, and when the control program of the air conditioner is executed by a processor, the relevant steps of any embodiment of the above control method of the air conditioner are implemented.
