Fig. 4 is a schematic flowchart of an air conditioner dehumidification control method according to a preferred embodiment of the present invention. As shown in fig. 4, in some embodiments of the present invention, the above step S302 may include the following sub-steps S3022 to S3026.
Substep S3022: the amount of air vapor in the room in which the indoor unit 100 of the air conditioner is located is determined.
In this step, first, the first temperature and the first humidity at the indoor unit 100, which are respectively detected by the temperature sensor 200 and the humidity sensor 300 disposed at the indoor unit 100, may be acquired. The amount of air water vapor in the room is then calculated based on the first temperature and the first humidity.
Specifically, calculating the amount of air water vapor in the room from the first temperature and the first humidity may be performed as follows:
first, a first air saturated water vapor pressure is calculated based on the first temperature. Can be specifically according to
Calculating a first air saturated water vapor pressure; where t1 is the first temperature and e _ s (t1) is the first air saturated water vapor pressure.
After the first air saturated water vapor pressure is obtained, a first air saturated water vapor amount is calculated according to the first temperature and the first air saturated water vapor pressure. Can be as follows

Substep S3024: the temperatures of a plurality of conditioning zones are acquired.
In this step, the temperatures of the multiple conditioning zones in the room can be detected and obtained by using infrared temperature measuring equipment.
In this step, the temperature is the average temperature of the adjustment area, the temperatures of a plurality of positions in the adjustment area can be detected by the infrared temperature measurement device 400, and the average temperature of the adjustment area can be obtained by calculating the average value.
Substep S3026: and respectively calculating the humidity of each adjusting area according to the temperature and the air water vapor amount of each adjusting area, thereby obtaining the humidity of a plurality of adjusting areas.
In this step, for each conditioning zone, the corresponding humidity may be calculated as follows.
First, according to
Calculating a second air saturated water vapor pressure; where t2 is the temperature of the conditioning zone and e _ s (t2) is the second air saturated water vapor pressure.
After a second air saturated water vapor pressure is obtained, according to
Calculating a second amount of air saturated water vapor; where a _ s (t2) is the second air-saturated water vapor amount.
After the second air saturated water vapor amount is obtained, the ratio of the air water vapor amount and the second air saturated water vapor amount is obtained as the humidity of the conditioning area.
And traversing each adjusting area to obtain the humidity of all adjusting areas.
Note that, a (t1) calculated in step S3022 above is actually the amount of air vapor at the first temperature, but since the air is uniform, it is considered that the amounts of air vapor at the temperature of the adjustment region and at the first temperature are the same.
In the above embodiment, after the amount of air vapor is obtained by using the temperatures and humidities detected by the temperature sensor 200 and the humidity sensor 300 provided in the indoor unit 100, the humidity of each of the adjustment areas can be calculated according to the amount of air vapor and the temperatures of the plurality of adjustment areas in the room detected by the infrared temperature measurement device 400, which is low in cost and convenient to arrange.
After acquiring the humidity of each adjustment area, the adjustment area having a humidity greater than the preset humidity threshold is set as a target area in step S304. The humidity threshold may be a value set by a person, or may be obtained by self-learning according to a humidity threshold set by a user in a past period of time, which is not particularly limited in the present invention.
Then, in steps S306 and S308, if it is determined that there are a plurality of target regions, whether there are human bodies in each of the plurality of target regions is scanned. If yes, controlling a refrigerating system of the air conditioner to operate in a set soft mode, determining an air supply mode of the indoor unit 100 to each target area according to the temperature of the target area, and controlling the indoor unit 100 to supply air to the target areas one by one according to the corresponding air supply mode. And in the soft mode, the running frequency of the compressor of the air conditioner is set to be less than a preset frequency threshold value. The refrigerating system of the air conditioner is controlled to operate in a set soft mode for a target area where a human body exists, so that the influence on the human body in the dehumidification process of the target area can be reduced as much as possible.
In addition, the controlling of the indoor unit 100 to blow air to the plurality of target areas one by one according to the corresponding air blowing modes mentioned in step S308 may specifically be controlling the indoor unit 100 to blow air to each target area one by one according to the corresponding mode in the sequence from high to low of the humidity of each target area, or according to the sequence set by the user, which is not particularly limited in the present invention.
In some embodiments of the present invention, the determining, according to the temperature of each target area, the blowing mode of the indoor unit 100 for the target area in step S304 specifically includes: and judging whether the temperature of the target area is higher than a preset temperature threshold value or not. Setting the air supply mode of the target area with the temperature higher than the preset temperature threshold value as directional air supply, and setting the air supply mode of the target area with the temperature lower than the preset temperature threshold value as back-and-forth air sweeping with the target area as the center. Thereby further reducing the influence on the human body in the dehumidification process of the indoor unit 100.
The directional air supply for the target area is to adjust the directions of the upper and lower air deflectors and the left and right swinging blades so that the indoor unit 100 supplies air for the target area, for example, if the target area is the first adjustment area B1, the left and right swinging blades are controlled to be in the first adjustment direction, and the upper and lower air deflectors are controlled to be in the fourth adjustment direction. If the wind swings back and forth aiming at the target area, the left and right swing blades and the upper and lower air guide plates can be controlled to rotate back and forth by taking the target area as the center, so that the wind is not always blown to the human body, and the influence on the human body can be reduced.
The temperature threshold may be set manually or obtained by self-learning based on a temperature threshold set by a user in a past period of time, which is not limited in the present invention.
In one example, the preset humidity threshold is 60%, the preset temperature threshold is 24 ℃, and three target areas, namely a first target area, a second target area and a third target area, exist in the room. Wherein the humidity of the first target area, the humidity of the second target area and the humidity of the third target area are 65%, 70% and 75%, respectively. The human body is present in the first target area, the second target area and the third target area. The temperatures of the first target region, the second target region and the third target region were 23 ℃, 27 ℃ and 30 ℃, respectively. The refrigeration system of the air conditioner is controlled to operate in a set soft mode, and the indoor unit 100 is controlled to directionally blow air to the third target area and the second target area one by one and to sweep air back and forth with the first target area as a center according to the sequence of the third target area, the second target area and the first target area.
In some embodiments of the present invention, when there are a plurality of target areas and no human body exists, the refrigeration system of the air conditioner is controlled to operate in the dehumidification mode, and the indoor unit 100 is controlled to directionally supply air to the plurality of target areas one by one. Specifically, the indoor unit 100 is preferably controlled to directionally dehumidify the target areas one by one in the order of the humidity of each target area from high to low. In the dehumidification mode, the operating frequency of the compressor of the air conditioner is set to be greater than a preset frequency threshold value, so that the humidity of a room can be reduced as soon as possible.
In one example, the preset humidity threshold is 60%, and there are three target zones in the room, a first target zone, a second target zone, and a third target zone. Wherein the humidity of the first target area, the humidity of the second target area and the humidity of the third target area are 65%, 70% and 75%, respectively. No human body is present in the first target area, the second target area and the third target area. The refrigeration system of the air conditioner is controlled to operate in a set dehumidification mode and the indoor unit 100 is controlled to perform directional air supply of the third target area, the second target area and the first target area one by one according to the sequence of the third target area, the second target area and the first target area.
In some embodiments of the present invention, in a case where there are a plurality of target areas and only some target areas have human bodies, the indoor unit 100 is controlled to preferentially and directionally blow air to the target areas without human bodies one by one. Therefore, the influence on the human body can be reduced as much as possible while the humidity of the room is reduced as soon as possible.
In order that the above-described aspects of the invention may be more clearly and clearly understood. The above method proposed by the present invention is fully and specifically explained below with reference to fig. 5, and specifically includes the following steps:
step S502: the humidity of each of a plurality of adjustment areas previously divided in a room in which an indoor unit 100 of an air conditioner is located is acquired, and the adjustment area having a humidity greater than a preset humidity threshold is set as a target area.
