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 or the air conditioner.
In an embodiment of the present invention, referring to fig. 1, the terminal includes: a processor 1001 (e.g., CPU (central processing unit, central processing unit)), a timer 1002, a memory 1003, and the like. The memory 1003 may be a high-speed RAM memory or a stable memory (non-volatile memory), such as a disk memory. The memory 1003 may alternatively be a storage device separate from the processor 1001 described above.
It will be appreciated by those skilled in the art that the terminal structure shown in fig. 1 is not limiting of the terminal and may include more or fewer components than shown, or may combine certain components, or a different arrangement of components.
It will be appreciated that in an embodiment, a control program for implementing the control procedure 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 indoor environment humidity and the fluctuation of the indoor environment temperature.
Based on the hardware architecture of the terminal, various embodiments of the control method of the air conditioner are provided.
Referring to fig. 2, a first embodiment of a control method of an air conditioner according to the present invention is presented. In this embodiment, the control method of the air conditioner includes:
step S10, when the air conditioner meets a humidifying condition, calculating a target dew point temperature according to set humidity of the air conditioner and 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 operation of the air conditioner according to the target evaporation temperature so as to reduce the indoor environment humidity and the fluctuation of the indoor environment temperature.
The embodiment of the invention can be implemented in an air conditioner or a control terminal of the air conditioner, and the embodiment is described by taking the air conditioner as an example.
Optionally, during the refrigerating process of the air conditioner, the indoor environment humidity gradually decreases along with the refrigerating duration. Too low humidity may affect indoor comfort, and thus, the air conditioner may perform humidification under certain conditions, such as slowing down a humidity reduction rate, or starting a humidification mode, etc., during operation. In an alternative embodiment, when the difference between the set humidity of the air conditioner and the indoor environment humidity where the air conditioner is located is greater than or equal to a second preset threshold, the air conditioner is determined to meet the humidification condition, where the second preset threshold is a preset relative humidity critical value for determining that the indoor environment humidity is lower.
Alternatively, 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 detecting that the difference 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 operation process of the air conditioner, when the evaporation temperature of the air conditioner is lower, the temperature of the indoor heat exchanger is lower, and when the evaporation temperature is lower than the dew point temperature of the indoor ambient air, the condensation phenomenon easily occurs in the indoor heat exchanger, and then the condition that the humidity of the indoor environment where the indoor unit of the air conditioner is located is rapidly reduced easily occurs.
Optionally, the target dew point temperature is an air dew point temperature corresponding to when the indoor environment humidity where the indoor unit of the air conditioner is located is humidified to a set humidity, and the target dew point temperature can 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 is obtained, the set humidity of the air conditioner is obtained; in one embodiment, according to the indoor environment temperature and the set humidity, inquiring a dew point thermometer to obtain the target dew point temperature; in another embodiment, the indoor environment temperature and the set environment temperature are substituted into a dew point calculation formula to obtain the target dew point temperature.
Optionally, the evaporating temperature corresponding to the set temperature may be a tube temperature of the indoor heat exchanger determined according to the set temperature, or be a target temperature corresponding to a current operation mode, or be an evaporating temperature determined according to an operation scenario of the air conditioner, or be determined according to a current environmental requirement of an environment where the indoor unit is located (where the environmental requirement includes only a refrigeration requirement), if the outdoor environment temperature where the air conditioner is located is acquired first, and the evaporating temperature corresponding to the set temperature is determined according to the set temperature, the outdoor environment temperature, and a difference value between the indoor environment temperature and the set temperature.
Optionally, the target evaporation temperature may be a target temperature corresponding to a current operation mode, or a target evaporation temperature determined according to an operation scenario of the air conditioner, or a target evaporation temperature determined according to a current environmental requirement of an environment where the indoor unit is located, where the target evaporation temperature is determined by acquiring a target dew point temperature, a preset correction value, and an evaporation temperature corresponding to a set temperature.
It can be appreciated that, with respect to the fixed target evaporation temperature, the embodiment calculates the target evaporation temperature in real time according to the current environmental requirement (the environmental requirement includes the humidity requirement and the temperature requirement) of the environment where the air conditioner is located, so that the accuracy of controlling the indoor environment temperature and the indoor environment humidity where the indoor unit is located can be improved, and the refrigeration effect and the humidification effect of the air conditioner simultaneously meet the user requirement.
It is understood that when the air conditioner is controlled to operate according to the target evaporation temperature, the indoor environment temperature where the air conditioner is located may change, for example, the air conditioner is still controlled to operate according to the target evaporation temperature, and the refrigeration effect is easily poor due to the higher target evaporation temperature.
In an 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, the step is performed in a return manner: the target dew point temperature is calculated according to the set humidity of the air conditioner and the indoor environment temperature where the air conditioner is located, and the target evaporation temperature of the air conditioner is further determined according to the target dew point temperature, a preset correction value and the evaporation temperature corresponding to the set temperature, so that the indoor environment temperature and the indoor environment humidity are monitored in real time, when the indoor environment temperature changes and the change amplitude is large, the target dew point temperature is determined again, and the target evaporation temperature is further determined according to the real-time environment requirement, so that the refrigerating effect and the humidifying effect of the air conditioner always fit the user requirement.
In another embodiment, a target dew point temperature is calculated according to a set humidity of an air conditioner and an indoor environment temperature where the air conditioner is located at intervals of a preset time, and a target evaporation temperature of the air conditioner is further determined according to the target dew point temperature, a preset correction value and an evaporation temperature corresponding to the set temperature.
In yet another embodiment, the dew point temperature of the environment in which the indoor unit of the air conditioner is located and the target evaporation temperature of the air conditioner are obtained, and each time a change in the indoor environment temperature and/or a change in the set humidity is detected, the execution step is returned to: and calculating a target dew point temperature according to the set humidity of the air conditioner and the indoor environment temperature of the air conditioner, further determining a target evaporation temperature of the air conditioner according to the target dew point temperature, a preset correction value and an evaporation temperature corresponding to the set temperature, and only when the parameters change in the embodiment, determining the target evaporation temperature again, so that the air conditioner is more energy-saving.
Therefore, when the indoor environment temperature and/or the set humidity and/or the set temperature change, the target dew point temperature is calculated for a plurality of times, and then the target evaporation temperature is determined for a plurality of times, so that the user demand and the indoor environment condition are monitored in real time, and the refrigerating effect and the humidifying effect of the air conditioner can meet the user demand simultaneously.
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 the evaporation temperature is corrected through the target dew point temperature and the preset correction value to obtain the target evaporation temperature. The target evaporating temperature is obtained by correcting the evaporating temperature based on the target dew point temperature and the preset correction value, so that the air condensation can be reduced to the greatest extent in the running process of the air conditioner according to the target evaporating temperature, the humidity is prevented from being reduced too low, the correction is performed on the basis of the evaporating temperature corresponding to the set temperature, 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 prevented, and the refrigerating effect and the humidifying effect of the air conditioner simultaneously meet the user demands.
Referring to fig. 3, a second embodiment of a control method of a multi-split air conditioner is proposed based on the above embodiment, in this embodiment, step S20 includes:
step S21, acquiring the indoor environment humidity of the air conditioner;
step S22, judging whether the indoor environment humidity is greater than or equal to the set humidity;
if yes, step S23 is executed, where a 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 an evaporation temperature corresponding to the set temperature;
if not, step S24 is executed to determine the target evaporation temperature of the air conditioner according to the sum of the target dew point temperature and the preset correction value and the evaporation temperature corresponding to the set temperature.
Optionally, in some embodiments, when the air conditioner just starts the cooling mode, the indoor environment temperature is higher, the indoor environment humidity is more than or equal to the set humidity easily, the evaporation temperature corresponding to the set temperature is lower, so that a proper amount of evaporation temperature is increased to obtain the target evaporation temperature, the air conditioner is controlled to operate according to the target evaporation temperature, so that air condensation is reduced, and rapid reduction of the indoor environment humidity after the air conditioner starts the cooling mode for a period of time is avoided.
Alternatively, in other embodiments, during the operation of the air conditioner in the cooling mode, the indoor environment temperature may be relatively moderate, and the indoor environment humidity may be relatively high, where 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 meets the user requirement, 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 is operated in the cooling mode for a period of time, the indoor environment temperature is lower, the indoor environment humidity is lower, the condition that the indoor environment humidity is lower than the set humidity easily occurs, the evaporation temperature corresponding to the set temperature is lower, 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, the air conditioner is controlled to operate according to the target evaporation temperature, and therefore the cooling effect of the air conditioner exceeds the user requirement and the humidifying effect does not meet the user requirement.
Optionally, in still other embodiments, after the air conditioner is operated 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, where the indoor environment humidity is smaller than the set humidity, and the calculated target dew point temperature is not different from the evaporation temperature corresponding to the set humidity, which indicates that the evaporation temperature corresponding to the set humidity is higher or moderate, where condensation generated on the surface of the indoor heat exchanger is less, that is, after the air conditioner is operated at the evaporation temperature for a period of time, the humidifying effect of the air conditioner may meet the user requirement, 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 of the air conditioner 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 an 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 of the air conditioner 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.
In this embodiment, the indoor environment humidity of the air conditioner is obtained first, whether the indoor environment humidity is greater than or equal to the set humidity is determined, if the indoor environment humidity is greater than or equal to the set humidity, it is indicated that the indoor environment humidity is greater, the target evaporation temperature of the air conditioner is determined according to the difference between the target dew point temperature and the preset correction value and the evaporation temperature corresponding to the set temperature, and the evaporation temperature is increased appropriately to obtain the target evaporation temperature, so as to reduce the air condensation to the greatest extent, thereby slowing down the reduction rate of the indoor environment humidity. 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 sum of the target dew point temperature and the preset correction value and the evaporation temperature corresponding to the set temperature, and the evaporation temperature is increased by a proper amount so as to improve the humidification effect of the air conditioner while guaranteeing the refrigeration effect of the air conditioner.
Optionally, referring to fig. 4, a third embodiment of a control method of a multi-connected air conditioner is proposed based on the above embodiment, and in this embodiment, step S23 includes:
executing step S231 to obtain a difference between the target dew point temperature and the preset correction value when the ambient humidity is greater than the set humidity;
step S232, judging whether the difference is larger than or equal to the evaporation temperature corresponding to the set temperature;
if yes, step S233 is executed, and the difference is taken 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, and may be determined according to the running scenario.
Optionally, in some embodiments, when the air conditioner just starts to perform refrigeration, 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 refrigeration process of the air conditioner, the indoor environment humidity is reduced, the difference between the indoor environment humidity and the set humidity is also reduced, if the air conditioner still uses a lower target evaporation temperature to perform operation, the indoor environment humidity is easy to be reduced rapidly, so 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, thereby improving the humidifying effect when the indoor environment temperature meets the user requirement; when the indoor environment temperature is higher, a smaller preset correction value is preset, the target evaporation temperature determined according to the preset correction value is smaller, but still larger than the evaporation temperature corresponding to the set temperature, so that the influence of humidification on the refrigerating effect is reduced.
In one embodiment, before the difference between the target dew point temperature and the preset correction value is obtained, 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 environment humidity is 65%, the preset correction value is 2.
As another embodiment, before the difference between the target dew point temperature and the preset correction value is obtained, the preset correction value is determined by obtaining the indoor environment humidity and the set humidity, and the preset correction value is adjusted according to the change value of the indoor environment humidity, for example, when the set humidity is 55%, the indoor environment humidity is 60%, the preset correction value is 1, and when the indoor environment humidity is increased by 5%, the preset correction value is 2.
Thus, when the indoor environment humidity is high, the target evaporation temperature is determined according to the indoor environment humidity and the set humidity, when the indoor environment humidity is high, the preset correction value is high, the determined target evaporation temperature is low, so that the refrigerating effect can be ensured, when the indoor environment humidity is low, the preset correction value is reduced, the determined target evaporation temperature is high, and the target evaporation temperature is always higher than or equal to the evaporation temperature corresponding to the set temperature, so that the rapid reduction of the indoor environment humidity can be slowed down.
In this embodiment, the difference between the target dew point temperature and the preset correction value is obtained first, and 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, the evaporation temperature is indicated to be too low at this time, and the difference is taken as the target evaporation temperature to properly raise the temperature of the indoor heat exchanger, so that the condensation phenomenon caused by the too low temperature of the indoor heat exchanger in the following process is avoided, further, the rapid reduction of the indoor environment humidity is avoided, and when the difference is less than the evaporation temperature corresponding to the set temperature, the evaporation temperature is indicated to be higher at this time, and no adjustment of the evaporation temperature is required.
Optionally, referring to fig. 5, a fourth embodiment of a control method of a multi-connected air conditioner is proposed based on the above embodiment, and in this embodiment, step S24 includes:
executing step S241 to obtain the sum of the target dew point temperature and the preset correction value when the ambient humidity is less than the set humidity;
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, and taking the sum value as the target evaporation temperature;
if not, step S244 is executed to take the evaporation temperature corresponding to the set temperature as the target evaporation temperature.
In this embodiment, when the indoor environment humidity is low, the temperature of the indoor heat exchanger is reduced by increasing the target evaporation temperature, so that condensation on the indoor heat exchanger is reduced, and when the target evaporation temperature is too high, the refrigeration effect of the air conditioner is easily caused to be poor.
Alternatively, the preset correction value may be a fixed preset value, and may be determined according to the running scenario.
As in one embodiment, the preset correction value is determined according to the indoor environment 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 environment temperature is 12 ℃, the preset correction value is 1, and when the indoor environment temperature is 8 ℃, the preset correction value is 3.
As 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.
In this way, 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 also lower, so that the refrigerating effect of the air conditioner can be ensured, when the indoor environment temperature is reduced, the preset correction value is increased, so that the determined target evaporation temperature is increased, namely, when the refrigerating effect of the air conditioner meets the user requirement, part of refrigerating capacity is sacrificed, so that the humidifying effect is improved, and the refrigerating effect and the humidifying effect of the air conditioner meet the user requirement simultaneously.
In addition, the embodiment of the invention also provides a computer readable storage medium, wherein the computer readable storage medium stores a control program of the air conditioner, and the control program of the air conditioner realizes the relevant steps of any embodiment of the control method of the air conditioner when being executed by a processor.
