Wherein, BPreset ofFor said predetermined temperature drop slope, f (N)Rotational speed）、f（FFrequency of）、f（SSize of room）、f（TOutdoors) Rotational speeds N corresponding to the gear positionsRotational speedFrequency FFrequency ofSize of room SSize of roomOutdoor ambient temperature TOutdoorsCorresponding dimension functions, a, b, c and d are weight values of the dimension functions respectively, the weight value range of each dimension function is 10% -50%, and the expression of each dimension function can be as follows:
wherein L isLong and long、LWidth of、LHeight ofRespectively the length, width and height of the room; t is a predetermined time length; t isIndoor useIs the indoor ambient temperature; ρ is the thermal temperature emissivity.
Step S140, determining the current humidity value of the room according to the deviation between the actual temperature falling slope and the preset temperature falling slope and the initial humidity value.
The deviation between the actual temperature decrease slope and the preset temperature decrease slope may be a percentage, that is, a deviation percentage, of a difference between the preset temperature decrease slope and the actual temperature decrease slope and the preset temperature decrease slope.
And if the deviation is smaller than a first preset value, determining the current humidity value of the room according to the initial humidity value and a first preset rule. The first preset rule may include, for example, the following formula:
wherein, y0For the initial humidity value of the room, m is the conversion coefficient of temperature and humidity, which may be a constant, and may be measured by experiment, i.e., the conversion coefficient of temperature and humidity Δ t may be measured by performing a large number of experiments with the doors and windows closedReal timeThe time interval from the initial starting time point (the time point of starting and operating the refrigeration or the defrosting) to the current time point, BReal timeIs the current actual temperature drop slope of the room. Specifically, if the deviation percentage k of the falling slope is less than the first preset value k1, it indicates that the doors and windows are closed, the sealing performance is relatively good, the influence of outdoor air is small, and the humidity value of the room can be calculated according to the above formula.
And if the deviation is greater than a first preset value and less than or equal to a second preset value, determining the current humidity value of the room according to the initial humidity value and a second preset rule. Specifically, if the deviation percentage k of the descending slope is greater than the first preset value k1 and less than or equal to the second preset value k2, it indicates that the indoor door and window is not closed well, and has a certain air flow circulation, for example, in the case of half-open door and window, affected by the external environment, and at this time, the temperature and humidity are still in consistency, and the current humidity value of the room can be determined according to the initial humidity value and the second preset rule.
If the deviation percentage k is greater than the first preset value k1 and less than or equal to the second preset value k2, it indicates that the indoor door and window is not closed well and has a certain air flow circulation, for example, the door and window is half-opened, at this time, the temperature and humidity decrease still show consistency, but the humidity and the indoor and outdoor conduction coefficients of the temperature are different, so the coefficients need to be changed. The second preset rule may for example comprise the following formula,
wherein, y0For the initial humidity value of the room, m is the conversion coefficient of temperature and humidity, in particular the conversion coefficient of temperature and humidity when the doors and windows are closed, may be a constant, and may be measured by experiments, i.e. the conversion coefficient of temperature and humidity when the doors and windows are closed, Δ tReal timeThe time interval from the initial starting time point (the time point of starting and operating the refrigeration or the defrosting) to the current time point, BReal timeIs the current actual temperature drop slope of the room, BPreset ofThe preset temperature drop slope is determined according to the room size, the operation parameters and the outdoor environment temperature.
And if the deviation is larger than a second preset value, determining the initial humidity value as the current humidity value of the room. Specifically, if the deviation percentage k of the falling slope is greater than the second preset value k2, it indicates that the indoor doors and windows are not closed well and have obvious airflow circulation, for example, the door and window are fully opened, and the estimated humidity y of the room is estimated at this time3For the obtained initial humidity value y0。
Optionally, when it is determined that the deviation is greater than the first preset value and less than or equal to a second preset value, that is, the indoor environment is in a closed state or a half-open state, then the actual temperature decrease slope of the indoor temperature is continuously obtained, if the temperature has abnormal variation (for example, the deviation of the temperature decrease slope is greater than the second preset value, that is, the deviation percentage k of the temperature decrease slope is greater than k2, or the indoor temperature does not decrease but rises), it indicates that a door and window is opened or airflow suddenly flows in the operation process, and the humidity value at this time is the current humidity value of the area where the air conditioning equipment is located, that is, the humidity value of the area queried in real time through wifi.
Optionally, the method may further include: and sending the current humidity value and/or humidity value change curve of the room to the mobile terminal, so that the user can check the current humidity value and/or humidity change curve of the room through the mobile terminal APP.
Optionally, the method may further include: and when the current humidity value of the room is smaller than a preset threshold value, sending a reminding message to the mobile terminal to remind a user that the room is too dry, and adjusting the humidity of the room in time.
The invention also provides a humidity detection device. The humidity detection method may be used for an air conditioning apparatus including an air conditioner and/or a dehumidifier. Specifically, when the air conditioning equipment is in a cooling mode or a dehumidification mode, the humidity detection device executes humidity detection control logic.

In a specific embodiment, an air conditioning device, such as an air conditioner, has a WiFi module, and a humidity value of a geographic location corresponding to an ip address of the air conditioning device is obtained through the WiFi module, for example, the humidity value of a city is queried by a city weather forecast issuing system through the WiFi module, so as to query the humidity value of the city as an indoor initial humidity value y0。
The second obtaining unit 120 obtains the current actual temperature decrease slope of the room in which the air conditioning equipment is operating. Specifically, the second obtaining unit 120 may obtain a temperature change value of an indoor ambient temperature of a room in which the air conditioning equipment is located within a predetermined time period; and determining the actual temperature reduction slope according to the ratio of the temperature change value to the preset time length.

In another embodiment, the determining subunit 132 calculates the preset temperature drop slope B according to the following formula according to the room size, the operating parameter and the outdoor environment temperaturePreset of：
Wherein, BPreset ofFor said predetermined temperature drop slope, f (N)Rotational speed）、f（FFrequency of）、f（SSize of room）、f（TOutdoors) Rotational speeds N corresponding to the gear positionsRotational speedFrequency FFrequency ofSize of room SSize of roomOutdoor ambient temperature TOutdoorsCorresponding dimension functions, a, b, c and d are weight values of the dimension functions respectively, the weight value range of each dimension function is 10% -50%, and the expression of each dimension function can be as follows:
wherein L isLong and long、LWidth of、LHeight ofRespectively the length, width and height of the room; t is a predetermined time length; t isIndoor useIs the indoor ambient temperature; ρ is the thermal temperature emissivity.
The determining unit 140 determines a current humidity value of the room according to a deviation between the actual temperature falling slope and the preset temperature falling slope and the initial humidity value.
The deviation between the actual temperature decrease slope and the preset temperature decrease slope may be a percentage, that is, a deviation percentage, of a difference between the preset temperature decrease slope and the actual temperature decrease slope and the preset temperature decrease slope.
And if the deviation is smaller than a first preset value, determining the current humidity value of the room according to the initial humidity value and a first preset rule. The first preset rule may include, for example, the following formula:
wherein, y0For the initial humidity value of the room, m is the conversion coefficient of temperature and humidity, which may be a constant, and may be measured by experiment, i.e., the conversion coefficient of temperature and humidity Δ t may be measured by performing a large number of experiments with the doors and windows closedReal timeThe time interval from the initial starting time point (the time point of starting and operating the refrigeration or the defrosting) to the current time point, BReal timeIs the current actual temperature drop slope of the room. Specifically, if the deviation percentage k of the falling slope is less than the first preset value k1, it indicates that the doors and windows are closed, the sealing performance is relatively good, the influence of outdoor air is small, and the humidity value of the room can be calculated according to the above formula.
And if the deviation is greater than a first preset value and less than or equal to a second preset value, determining the current humidity value of the room according to the initial humidity value and a second preset rule. Specifically, if the deviation percentage k of the descending slope is greater than the first preset value k1 and less than or equal to the second preset value k2, it indicates that the indoor door and window is not closed well, and has a certain air flow circulation, for example, in the case of half-open door and window, affected by the external environment, and at this time, the temperature and humidity are still in consistency, and the current humidity value of the room can be determined according to the initial humidity value and the second preset rule.
If the deviation percentage k is greater than the first preset value k1 and less than or equal to the second preset value k2, it indicates that the indoor door and window is not closed well and has a certain air flow circulation, for example, in the case of half-open door and window, the temperature drop and the humidity drop trend are still consistent, but the humidity and the indoor and outdoor conduction coefficients of the temperature are different, so the coefficients need to be changed. The second preset rule may for example comprise the following formula,
wherein, y0For the initial humidity value of the room, m is the conversion coefficient of temperature and humidity, in particular the conversion coefficient of temperature and humidity when the doors and windows are closed, may be a constant, and may be measured by experiments, i.e. the conversion coefficient of temperature and humidity when the doors and windows are closed, Δ tReal timeThe time interval from the initial starting time point (the time point of starting and operating the refrigeration or the defrosting) to the current time point, BReal timeIs the current actual temperature drop slope of the room, BPreset ofThe preset temperature drop slope is determined according to the room size, the operation parameters and the outdoor environment temperature.
And if the deviation is larger than a second preset value, determining the initial humidity value as the current humidity value of the room. Specifically, if the deviation percentage k of the falling slope is greater than the second preset value k2, it indicates that the indoor doors and windows are not closed well and have obvious airflow circulation, for example, the door and window are fully opened, and the estimated humidity y of the room is estimated at this time3Is still the initial humidity value y obtained0。
Optionally, when the humidity determining unit 140 determines that the deviation is greater than the first preset value and less than or equal to the second preset value, that is, the indoor is in the closed state or the half-open state, then the second obtaining unit 120 continues to obtain the actual temperature decrease slope of the indoor temperature, and if the temperature has abnormal variation (for example, the deviation of the temperature decrease slope is greater than the second preset value, that is, the deviation percentage k of the temperature decrease slope is greater than k2, or the indoor temperature does not decrease but rises), it indicates that the door and window is opened or the airflow is suddenly circulated in the operation process, and the humidity determining unit 140 determines the current humidity value as the current humidity value of the area where the air conditioning equipment is located, that is, the humidity value of the area queried in real time through wifi.
Optionally, the apparatus may further include: and the sending unit (not shown) is used for sending the current humidity value and/or humidity value change curve of the room to the mobile terminal, and/or sending a reminding message to the mobile terminal when the current humidity value of the room is smaller than a preset threshold value.
