In order to solve the problem of idle in a special mode and improve the comfort of the air conditioner, an embodiment of the present invention provides a control method of an air conditioner, as shown in fig. 2, the method may include:
201. the current temperature and the current relative humidity of the indoor environment are detected.
The air conditioner can start an intelligent control function after receiving an automatic control instruction sent by a user through a remote controller, a wire controller or an intelligent terminal, and detect the outdoor environment temperature and the indoor environment temperature and relative humidity in real time, so that the current season is determined according to the outdoor environment temperature and the indoor environment relative humidity, and the operation mode of the current season is determined for the first time according to the indoor environment temperature and the indoor environment relative humidity. Wherein, the current season can be any one of a refrigeration season, a heating season and a plum rain season.
The process of the air conditioner for determining the current season is as follows: if the outdoor environment temperature is greater than or equal to a first preset value, the season is a refrigeration season; if the outdoor environment temperature is less than or equal to a second preset value, the season is a heating season; and if the outdoor environment temperature is greater than the second preset value and less than the first preset value, and the indoor environment relative humidity is greater than or equal to the first humidity value, the season is plum rain. Further, in order to distinguish different climates included in the plum rain season, the plum rain season may be more finely divided. Specifically, under the condition that the relative humidity is greater than or equal to the first humidity value, if the outdoor environment temperature is greater than the second preset value and less than or equal to the third preset value, the climate is a cold and high-humidity climate in plum rain season, and if the outdoor environment temperature is greater than the third preset value and less than the first preset value, the climate is a coastal medium-temperature and high-humidity climate in plum rain season.
And the air conditioner can determine the operation mode of the current season for the first time and operate according to the operation mode when the temperature and the relative humidity of the indoor environment meet the preset conditions. However, since the temperature and the relative humidity of the indoor environment change with the increase of the operation time, the air conditioner can switch between all the operation modes in the current season according to the change of the indoor environment after the operation of the operation mode determined for the first time, so as to realize the constant temperature and the constant humidity under the full working condition. In a specific implementation, the air conditioner describes the switching process by taking as an example the detection of the current temperature and the current relative humidity of the indoor environment.
It should be noted that, the operation mode corresponding to each season may be pre-stored in the air conditioner, such as: the operation modes corresponding to the refrigeration seasons comprise a refrigeration mode, a dehumidification mode and an air supply mode; the operation mode corresponding to the heating season comprises a heating mode; the operation modes corresponding to the plum rain season comprise a dehumidification mode, an electric heating dehumidification mode, a combined dehumidification mode, an air supply mode and a heating mode. And prestoring the optimal set temperature in each season, such as: heating set value, refrigerating set value and plum rain set value.
202. And if the current temperature and the current relative humidity meet preset conditions, switching from the current operation mode to the target mode.
After detecting the current temperature and the current relative humidity of the indoor environment, if the current temperature and the current relative humidity meet preset conditions, the air conditioner is switched from the current operation mode to a target mode, wherein the current operation mode and the target mode are both operation modes included in the current season. Specifically, the method comprises the following steps:
when the current season is a refrigeration season, if the current relative humidity is smaller than a second humidity value and the current temperature is larger than or equal to a first preset temperature value, or the current temperature is larger than or equal to a refrigeration set value and smaller than the first preset temperature value, the target mode is a refrigeration mode. And if the current relative humidity is greater than or equal to the second humidity value and the current temperature is greater than or equal to the refrigeration set value and less than a first preset temperature value, the target mode is the dehumidification mode. And if the current temperature is less than the refrigeration set value, the target mode is an air supply mode.
When the current season is plum rainy season, if the current temperature is greater than or equal to a second preset temperature value, the target mode is the dehumidification mode. Under the condition that the current temperature is greater than or equal to a third preset temperature value and less than a second preset temperature value, if the current relative humidity is greater than or equal to the third humidity value, the target mode is an electric heating dehumidification mode; and if the current relative humidity is smaller than the third humidity value, the target mode is an air supply mode. Under the condition that the current temperature is lower than a third preset temperature value, if the current relative humidity is higher than or equal to a third humidity value, the target mode is a combined dehumidification mode; if the current relative humidity is less than the third humidity value, the target mode is a heating mode. The second preset temperature value may be (mei rain set value +. DELTA.T), the third preset temperature value may be (mei rain set value-. DELTA.T), and the third humidity value may be (second humidity value-. DELTA.T).
It should be noted that, when the current season is the heating season, the heating season only includes the heating mode, so that the air conditioner can operate the heating mode after determining that the current temperature is lower than the heating set value and determining the heating mode in the heating season for the first time, without switching the modes. Further, for the air conditioner with the humidifying function, if the current relative humidity is smaller than a preset threshold value, the humidifying function is started, and if the current relative humidity is larger than or equal to the preset threshold value, the humidifying function is closed or a humidifying gear is turned down.
203. And controlling the air conditioner to operate according to the target mode.
After the current operation mode is switched to the target mode, the air conditioner can operate according to the target mode. Specifically, the target mode can be operated in N preset stages, N is an integer larger than 1, and in the N preset stages, different stages comprise preset set temperature, wind speed and wind direction, and the set temperature, the wind speed and the wind direction are set by a professional angle as a user, so that the target mode is more suitable for the user requirement, and intelligent control is realized.
For example, assuming that N is 3, the 3 preset stages include: an initial phase, a stabilization phase and an energy saving phase. When the target mode is a refrigeration mode in a refrigeration season, the set temperature in the initial stage is refrigeration set temperature-delta T1, the wind speed is a high gear, and the wind direction is the position with the largest wind output so as to realize quick refrigeration; in the stabilization stage, the set temperature is refrigeration set temperature, the wind speed is middle and high gear, and the wind direction is ceiling air supply and is not easy to blow people; in the energy-saving stage, the set temperature is refrigeration set temperature + [ delta ] T2, the wind speed is in a middle-low gear, and the wind direction is the ceiling for supplying wind. When the target mode is an electric heating dehumidification mode in a plum rain season, the set temperature in the initial stage is plum rain set temperature-delta T3, the wind speed is a low gear, and the wind direction supplies wind to a ceiling, so that the influence on the indoor environment temperature is reduced while the dehumidification is fast; in the stable stage and the energy-saving stage, the set temperature is plum rain set temperature, the wind speed is low gear, and the wind direction supplies air to the ceiling. When the target mode is a heating mode in a heating season, the set temperature in the initial stage is heating set temperature + [ delta ] T4, the wind speed is a high gear, and the wind direction is the position with the largest wind output so as to realize rapid heating; in the stabilization stage, the set temperature is the heating set temperature, the wind speed is a middle-high gear, and the wind direction is the floor for supplying air; in the energy-saving stage, the set temperature is heating set temperature-delta T5, the wind speed is a middle-low gear, and the wind direction is floor air supply.
Further, when the air conditioner is provided with a sensor for sensing the temperature and the cold, identifying the position and measuring the distance of the human body, the air conditioner is divided into N preset stage operation target modes, and the air conditioner can specifically comprise: the air conditioner detects the human body temperature and cold perception, the position of the user and the distance between the air conditioner and the user, and adjusts the set temperature, the set wind speed and the set wind direction of each stage in N preset stages included in the target mode according to the pre-stored rule, so that the set parameters can better meet the requirements of the user. Wherein, as shown in table 1, the results are the human body temperature and cold sensing detection results.

Like this, according to the change of the temperature of indoor environment and relative humidity, switch between the operation mode under the current season of locating, not only can reach energy-conserving and healthy purpose with the angle automated determination operation mode of specialty, and can switch over the operation mode along with the condition change under the current season of locating for the operation mode more laminates user's demand, has improved user's comfort level.
