Second embodiment
Referring to fig. 5, the present embodiment provides a dehumidification control method, and the dehumidification control method provided in the present embodiment is applied to the air conditioner 100 provided in the first embodiment, and can achieve the purpose of constant temperature dehumidification in the dehumidification process of the air conditioner 100, so as to improve the experience of the user.
The method comprises the following specific steps:
in step S110, the air conditioner 100 is controlled to enter the dehumidification mode in response to the dehumidification start instruction.
In this embodiment, after the air conditioner 100 receives the dehumidification start instruction, the air conditioner 100 is controlled to enter the dehumidification mode, and the following steps may be performed after the air conditioner 100 receives the dehumidification start instruction.
In step S120, an indoor ambient humidity value of the air conditioner 100 is obtained.
In the present embodiment, the ambient humidity value is a real-time humidity value of the room where the air conditioner is currently located when the air conditioner 100 enters the dehumidification mode.
Step S122, determining whether the ambient humidity value is greater than a first preset humidity value.
In this embodiment, the first preset humidity value may be a humidity value set by the user according to the user's own needs, or may be a humidity value preset by the system in the air conditioner 100.
In step S124, when the ambient humidity value is greater than the first preset humidity value, the air conditioner 100 is controlled to enter the dehumidification mode.
In this embodiment, when the ambient humidity value is greater than the first preset humidity value, it indicates that the ambient humidity value in the room is relatively large, and it is necessary to perform dehumidification on the room. At this time, the air conditioner 100 is controlled to enter the dehumidification mode.
Step S126, determining whether the ambient humidity value is less than a second preset humidity value.
In this embodiment, the second preset humidity value may be a humidity value set by the user according to the user's own needs, or may be a humidity value preset by the system in the air conditioner 100.
And step S128, when the ambient humidity value is smaller than a second preset humidity value, controlling the compressor of the air conditioner 100 to stop. Wherein the second preset humidity value is smaller than the first preset humidity value.
In this embodiment, when the ambient humidity value is smaller than the second preset humidity value, it indicates that the indoor ambient humidity value is relatively low, and the compressor is controlled to stop, so as to prevent the indoor ambient humidity value from being relatively low, and the compressor is started to dehumidify, thereby damaging the air conditioner 100.
In the present embodiment, the user can set the target humidity Hs. In a constant-temperature dehumidification state, when the environment humidity value Ha is greater than Hs + N1, starting the compressor to operate and entering a dehumidification mode; when the ambient humidity Ha < Hs + N2, the compressor of the air conditioner 100 stops operating. That is, in the present embodiment, the first predetermined humidity value Hs + N1 and the second predetermined humidity value Hs + N2 are set. When the ambient humidity Hs + N2< Ha < Hs + N1 is in this range, the air conditioner 100 does not enter the dehumidification mode and operates normally. The N1 and N2 users can adjust the difference according to their own needs, and may be difference values stored inside the air conditioner 100.
In this embodiment, when the air conditioner 100 simultaneously obtains the dehumidification start instruction and the ambient humidity value is greater than the first preset humidity, the dehumidification mode may be entered, and the following steps are performed.
It should be noted that, in other embodiments of the present invention, the following steps may be executed after the air conditioner 100 receives the dehumidification start instruction, without including step S120, step S122, step S124, step S126, and step S128.
In step S130, an ambient temperature value of the room where the air conditioner 100 is located is obtained.
In the present embodiment, the ambient temperature value is a real-time temperature value of the room in which the air conditioner is currently located when the air conditioner 100 enters the dehumidification mode.
Step S140, determining whether the ambient temperature value is within a preset temperature range.
In this embodiment, after the environmental temperature value is obtained, it is determined whether the environmental temperature value is within a preset temperature interval, when the environmental temperature value is within the preset temperature interval, the execution is performed according to step S150, and when the environmental temperature value is not within the preset temperature interval, it is further determined whether the environmental temperature value is greater than an upper limit value of the preset temperature interval or less than a lower limit value of the preset temperature interval.
Step S150, when the ambient temperature value is within the preset temperature range, controlling the second chamber 22 to be communicated with the first exhaust port 24, so that the hot air generated in the second chamber 22 enters the room through the first exhaust port 24.
In this embodiment, when the ambient temperature value is in the preset temperature interval, it indicates that the current indoor ambient temperature value is in a temperature range where the user can perceive more comfortably, after entering the dehumidification mode, the ambient temperature value is required to be kept in the preset temperature interval, the second chamber 22 can be controlled to be conducted with the first exhaust port 24, so that the hot air generated by the heat exchange of the air conditioner 100 enters the indoor from the first exhaust port 24, the indoor ambient temperature value is kept not to be reduced, the purpose of constant temperature dehumidification is achieved, and the mode is the constant temperature dehumidification mode.
In this embodiment, when the ambient temperature value is within the preset temperature range, the controller 10 controls the driver 51 to drive the baffle 52 to rotate, so that the baffle 52 rotates to be matched with the second air outlet 25, the second chamber 22 and the second air outlet 25 are cut off, the second chamber 22 is communicated with the first air outlet 24, hot air generated by heat exchange of the air conditioner 100 is exhausted into the room through the first air outlet 24, and the indoor ambient temperature value is kept stable while dehumidification is performed.
In step S160, when the ambient temperature value is not within the preset temperature range, the second chamber 22 is controlled to be communicated with the second air outlet 25, so that the hot air or the cold air generated in the second chamber 22 is exhausted from the second air outlet 25.
In this embodiment, when the ambient temperature value is not within the preset temperature range, it indicates that the current indoor ambient temperature value is higher or lower, and cannot be in the constant temperature dehumidification mode. And corresponding adjustment is needed according to the actual ambient temperature value. When the ambient temperature value is too high, the ambient temperature value needs to be reduced by indoor refrigeration, and the hot air generated in the second chamber 22 is exhausted out of the room through the second air outlet 25. When the ambient temperature value is low, the current ambient temperature value needs to be increased by heating the indoor space, and the cold air generated in the second chamber 22 is exhausted from the outdoor space through the second air outlet 25.
Referring to fig. 6, in the present embodiment, step S160 may include step S161, step S162, step S163, step S164 and step S165.
Step S161, when the ambient temperature value is not within the preset temperature interval, determining whether the ambient temperature value is greater than or equal to an upper limit value of the preset temperature interval.
In this embodiment, when the ambient temperature value is not within the preset temperature interval, it needs to be determined that the ambient temperature value is greater than or equal to the upper limit value of the preset temperature interval, and then corresponding steps are executed according to the determination result.
In step S162, when the ambient temperature value is greater than or equal to the upper limit value of the preset temperature interval, the second chamber 22 is controlled to be communicated with the second air outlet 25, so that the hot air generated in the second chamber 22 is exhausted out of the room through the second air outlet 25.
In this embodiment, when the ambient temperature value is greater than or equal to the upper limit value of the preset temperature interval, it indicates that the current indoor ambient temperature value is higher, the current indoor ambient temperature value needs to be reduced while dehumidifying, at this moment, the second chamber 22 is controlled to be communicated with the second air outlet 25, so that the hot air generated by the heat exchange of the air conditioner 100 is discharged to the outside from the second air outlet 25, the hot air is prevented from entering the room, the indoor ambient temperature value is continuously increased, and the indoor ambient temperature value is reduced while dehumidifying.
In this embodiment, when the ambient temperature value is greater than or equal to the upper limit value of the preset temperature range, the controller 10 controls the baffle 52 to rotate through the driver 51, so that the baffle 52 rotates to be matched with the first exhaust opening 24, the second chamber 22 is communicated with the second exhaust opening 25, and the hot air generated by heat exchange of the air conditioner 100 is exhausted from the second exhaust opening 25 to the outside. At this time, this mode is the dehumidification only mode.
Step S163, when the ambient temperature value is not within the preset temperature interval, determining whether the ambient temperature value is smaller than a lower limit value of the preset temperature interval.
In this embodiment, when the ambient temperature value is not within the preset temperature interval, it is determined whether the ambient temperature value is smaller than a lower limit of the preset temperature interval, and corresponding steps are executed according to the determination structure.
In step S164, when the ambient temperature value is smaller than the lower limit value of the preset temperature interval, it is determined whether the ambient temperature value is greater than or equal to a first preset temperature value.
In this embodiment, when the ambient temperature value is smaller than the preset temperature interval, it indicates that the current ambient temperature value is relatively low, and the relationship between the current ambient temperature value and the first preset temperature value needs to be further determined, so that the air conditioner 100 executes the corresponding mode.
Step S165, when the ambient temperature value is greater than or equal to the first preset temperature value and less than the lower limit value of the preset temperature range, controlling the air conditioner 100 to start the heating mode, and controlling the second chamber 22 to be communicated with the second air outlet 25, so that the cold air generated in the second chamber 22 is discharged out of the room through the second air outlet 25.
In this embodiment, when the ambient temperature value is greater than or equal to the first preset temperature value and less than the lower limit of the preset temperature interval, it indicates that the current indoor ambient temperature value is relatively low, and the indoor ambient temperature value cannot reach a comfortable temperature interval only in the constant temperature dehumidification mode, at this time, the heating mode needs to be started to heat the indoor space, and the hot air generated in the first chamber 21 enters the indoor space through the air outlet 23. Meanwhile, the controller 10 controls the baffle 52 to rotate to be matched with the first air outlet 24 through the driver 51, so that the second chamber 22 is communicated with the second air outlet 25, and cold air generated by heat exchange of the air conditioner 100 is exhausted to the outside from the second air outlet 25. This mode is a heating mode.
And step S170, controlling the compressor of the air conditioner 100 to stop operating when the ambient temperature value is less than a first preset temperature value.
In this embodiment, when the ambient temperature value is less than a first preset temperature value, it indicates that the ambient temperature value in the current room is extremely low, and when the ambient temperature value is not within the temperature range of the normal operation of the compressor, at this moment, the compressor is controlled to stop operating, the compressor is protected, the compressor is prevented from being operated at the extremely low ambient temperature value, the compressor is damaged, and the compressor is in the shutdown protection mode at this moment.
The operating principle of the dehumidification control method provided by the embodiment is as follows: in this embodiment, after the air conditioner 100 enters the dehumidification mode, it is determined whether the ambient temperature value is within a preset temperature range, when the ambient temperature value is within the preset temperature range, the air conditioner 100 enters the constant temperature dehumidification mode, when the ambient temperature value is greater than or equal to an upper limit value of the preset temperature range, the air conditioner 100 enters the dehumidification-only mode, when the ambient temperature value is less than a lower limit value of the preset temperature range, it is determined whether the ambient temperature value is greater than a first preset temperature value, when the ambient temperature value is greater than or equal to the first preset temperature value and less than the lower limit value of the preset temperature range, the air conditioner 100 enters the heating mode, and when the ambient temperature value is less than the first preset temperature value, the compressor is controlled to stop operation.
In summary, in the dehumidification control method provided in this embodiment, when the ambient temperature value is greater than the upper limit value of the preset temperature interval, the air conditioner 100 enters the dehumidification-only mode to reduce the ambient temperature in the room to the preset temperature interval and execute the constant temperature dehumidification mode, and when the ambient temperature value is less than the lower limit value of the preset temperature interval, the air conditioner 100 enters the heating mode to gradually increase the ambient temperature value in the room to the preset temperature interval and execute the constant temperature dehumidification mode, so that the ambient temperature value in the room is maintained in the preset temperature interval, so that the user is in a comfortable temperature interval, and the experience of the user is improved.

When the environmental temperature value is less than the set temperature value, the upper limit value of the constant temperature dehumidification mode is a fifth preset temperature value, and the lower limit value of the constant temperature dehumidification mode is a third preset temperature value. That is, the first temperature interval of the constant temperature dehumidification mode when the ambient temperature value is greater than or equal to the set temperature value is less than the second temperature interval when the ambient temperature value is less than the set temperature value. When the ambient temperature value is greater than or equal to the set temperature value, it is indicated that the current ambient temperature value is higher, the temperature interval which is more comfortable for the user is lower, and when the ambient temperature value is in a descending trend, the ambient temperature value needs to be reduced to the first temperature interval with lower temperature for stabilization. Similarly, when the ambient temperature value is smaller than the set temperature value, it indicates that the current ambient temperature value is lower, and the temperature interval that is more comfortable for the user is higher, and when the ambient temperature value is in the rising trend, it is necessary to stabilize the temperature of the ambient temperature value in the second temperature interval that is higher.
For example: when the set temperature value is the third preset temperature value, the current ambient temperature value is the fourth preset temperature value, and the ambient temperature value is greater than the set temperature value, at this time, the air conditioner 100 executes the dehumidification-only mode.
Similarly, when the set temperature value is the fifth preset temperature value, the current ambient temperature value is the fourth preset temperature value, and the ambient temperature value is smaller than the set temperature value, at this time, the air conditioner 100 executes the constant temperature dehumidification mode.
