It should be noted that if the user directly presses the remote control dehumidification button when the cooling mode is not turned on, the user can directly enter the normal dehumidification mode. That is, the present invention does not require a change in the structure of the existing remote controller for an air conditioner, and accordingly, does not affect the operation of the existing cooling mode and dehumidifying mode.
When getting into the dehumidification mode under the refrigeration mode, indoor ambient temperature, indoor relative humidity and inner disc temperature are acquireed to the corresponding sensor of accessible to according to the operating parameter of fan and compressor in indoor ambient temperature, indoor relative humidity and the inner disc temperature regulation, then when control air conditioner carries out the refrigeration, can also carry out effective dehumidification.

After the moisture-proof function is turned on, the air conditioner may preferably be continuously operated for a certain period of time, for example, 2min, and then the collected indoor ambient temperature may be compared with the set temperature. Let the indoor ambient temperature be TInner ringSetting the temperature to TSetting upFor example, T is set by the remote controller of the air conditioner when the room temperature is approximately 36 deg.CSetting upWhen the air conditioner starts to cool at 26 ℃, the indoor ambient temperature gradually decreases. When T isInner ringSufficiently close to TSetting upWhen the temperature reaches the refrigerating temperature required by the user, the dehumidifying action is carried out after the problem that the user feels uncomfortable due to the room temperature is avoided, and more specifically, the operation parameters of the inner fan and the compressor are adjusted.

Specifically, when the difference between the indoor ambient temperature and the set temperature is less than or equal to a preset difference, or in other words, when | T |Setting up-TInner ringAt | < 1 ℃, e.g. TSetting up26 ℃ and TInner ringHas reached 25-27 ℃. I.e. TInner ringSufficiently close to TSetting upAnd then, corresponding dehumidification is carried out. When TSetting up-TInner ringIf | is more than 1 ℃, the system continues to operate in the refrigeration mode for a period of time, such as 2min, and then the temperature is judged again until | T ℃ |Setting up-TInner ring|＜1℃。
In this embodiment, only when indoor ambient temperature and the settlement temperature are close enough, just begin corresponding dehumidification operation, can guarantee like this that indoor temperature has basically reached user's demand, then adjust the running state of internal fan and compressor, and then under the prerequisite of basically maintaining indoor temperature, constantly improve indoor humidity to compromise the requirement of user to temperature and humidity, improve user's body and feel the comfort level.
Optionally, the controlling the inner fan and the compressor according to the indoor ambient temperature, the indoor relative humidity, and the inner disc temperature includes:
and when the indoor relative humidity is greater than a preset first humidity, determining the dew point temperature according to the indoor relative humidity and the indoor environment temperature.
And controlling the inner fan and the compressor according to the dew point temperature and the inner disc temperature.
Specifically, since the relative humidity range in which a general human body feels comfortable is 40% to 60%, the preset first humidity may be set to 60%, and accordingly, the preset second humidity may also be set to 40%.
When the indoor relative humidity is greater than the preset first humidity, that is, HInner partWhen the humidity is higher than 60%, the indoor relative humidity is higher, and the user feels uncomfortable. The inner disc temperature T can be obtained at this timeInner discAt the same time, according to TInner ringAnd HInner partDetermination of the dew point temperature TDew point。
It should be noted that the determination of the dew point temperature can be performed by using an psychrometric chart of the air, for example, knowing the indoor ambient temperature and the relative humidity, the dew point temperature can be directly known from the relationship between the indoor ambient temperature and the relative humidity and the dew point temperature. In addition, the dew point temperature may vary from environment to environment. This is the prior art and will not be described herein.
Inner disc temperature TInner discFor indicating the parameters of the state of the air conditioner, by the ambient indoor temperature TInner ringAnd indoor relative humidity HInner partDetermined dew point temperature TDew pointA parameter indicating the environment. The method and the device are combined, so that the influence of the air conditioner operation on the indoor environment can be accurately predicted, and further, the operation parameters of the internal fan and the compressor are properly adjusted.
In this embodiment, when indoor ambient humidity is higher than human comfortable humidity range, through the indoor ambient temperature who instructs environmental parameter and the dew point temperature that indoor relative humidity confirms, combine the inner disc temperature who instructs air conditioner self state parameter, can carry out accurate adjustment to the running state of internal fan and compressor to under the refrigerated prerequisite of assurance, effectively reduce indoor humidity, compromise the requirement of user to temperature and humidity, improve user's body and feel the comfort level.
Optionally, the controlling the inner fan and the compressor according to the dew point temperature and the inner disc temperature includes:
and when the temperature of the inner disc is greater than or equal to the dew point temperature, controlling the rotating speed of the inner fan to be reduced by one gear and the frequency of the compressor to be increased by one gear until the indoor relative humidity is less than or equal to the preset first humidity.
Specifically, when the inner disk temperature is greater than or equal to the dew point temperature, i.e., TInner disc≥TDew pointAnd when the temperature of the indoor air is not changed, the rotating speed of the inner fan is controlled to be reduced by one gear, the frequency of the compressor is controlled to be increased by one gear, and the operation can be continued for a period of time, for example, 1min, so that the indoor humidity can be effectively reduced under the condition that the room temperature is not changed obviously. Accordingly, TInner disc＜TDew pointIf so, the operation is continued in the cooling mode for a period of time, for example, 2min, and then the humidity judgment is performed again. The process is circulated until HInner part≤60％。
More specifically, when the inner panel temperature is greater than or equal to the dew point temperature, which indicates that condensation is not generally generated by the air conditioner, a corresponding power consumption may be reduced by performing a downshifting of the fan. Because the air volume becomes small, the heat exchange becomes poor, the temperature of the inner disc will drop, and the temperature of the inner disc can be further reduced by executing the frequency increasing of the compressor. When the temperature of the inner disc is lower than the dew point temperature, the air conditioner can normally perform refrigeration operation.
In this embodiment, when indoor environment humidity is higher than the comfortable humidity range of human body, through the relation of inner disc temperature and real-time dew point temperature, when inner disc temperature is higher than real-time dew point temperature, fan windshield and compressor frequency in the adjustment to under the refrigerated prerequisite of guaranteeing, effectively reduce indoor humidity, compromise the requirement of user to temperature and humidity, improve user's body and feel the comfort level.
Optionally, the controlling the inner fan and the compressor according to the dew point temperature and the inner disc temperature further includes:
and when the rotating speed of the inner fan is the lowest gear, the rotating speed of the inner fan is kept to be the lowest gear.
Specifically, because temperature humidity control is mainly carried out through turning down the mode of wind shelves and accent high frequency this moment, when the rotational speed of interior fan was minimum, just kept minimum grade unchangeable, only adjusted compressor operating frequency.
It should be noted that, as the operating frequency of the compressor increases, the temperature of the inner disc decreases, and in the case that the humidity of the indoor environment is greater than 60%, that is, in the case of high humidity, the compressor can find the corresponding frequency that the temperature of the inner disc is less than the dew point temperature before increasing to the maximum frequency, and enter the initial state, so that there is no need to worry about the situation that the compressor does not dehumidify when increasing to the maximum frequency, and at this time, the inner fan is in a low wind range, which makes it easier to decrease the temperature of the inner disc.
In this embodiment, because the humiture is adjusted in order to adjust through the running state of controlling interior fan and compressor, when the rotational speed of interior fan dropped to minimum, still accessible control compressor operating frequency adjusted, and the reliability is higher.
Optionally, the controlling the inner fan and the compressor according to the indoor ambient temperature, the indoor relative humidity, and the inner disc temperature further includes:
and when the indoor relative humidity is smaller than a preset second humidity, determining the dew point temperature according to the indoor relative humidity and the indoor environment temperature, wherein the preset second humidity is smaller than the preset first humidity.
And controlling the inner fan and the compressor according to the dew point temperature and the inner disc temperature.
Specifically, when the indoor relative humidity is less than the preset second humidity, i.e., HInner partIf the humidity is less than 40%, the indoor relative humidity is low, and the discomfort of the user can be caused. Can be acquired at this timeDisc temperature TInner discAt the same time, according to TInner ringAnd HInner partDetermination of the dew point temperature TDew point。

Optionally, the controlling the inner fan and the compressor according to the dew point temperature and the inner disc temperature includes:
and when the temperature of the inner disc is less than or equal to the dew point temperature, controlling the rotating speed of the inner fan to be increased by one gear and the frequency of the compressor to be reduced by one gear until the indoor relative humidity is greater than or equal to the preset second humidity.
Specifically, when the inner disk temperature is less than or equal to the dew point temperature, i.e., TInner disc≤TDew pointDuring the time, the rotating speed of the inner fan is controlled to be increased by one gear, the frequency of the compressor is reduced by one gear, and the operation can be continued for a period of time, for example, 1min, so that the indoor humidity can be increased to a range which is in accordance with the comfort level of a human body under the condition that the room temperature is not remarkably changed, and the indoor drying is prevented. Accordingly, TInner disc＞TDew pointAnd then the circulation is skipped to avoid excessive dehumidification. The process is circulated until HInner part≥40％。
