The indoor humidity control method provided by the embodiment of the invention is applied to an air conditioner. The indoor humidity control method provided by the embodiment of the invention comprises the steps S1 to S5.
S1, acquiring the indoor volume of the space where the air conditioner is located and the relative humidity of the area where the air conditioner is located from a server.
In this embodiment, the humidity control information refers to a house type map where the air conditioner is located, a floor height, an area where the air conditioner is located, and the like. When the air conditioner is started, acquiring humidity control information uploaded to a server by a user; the server recognizes and calculates the humidity control information, so that the air conditioner obtains the indoor volume of the space where the air conditioner is located and the relative humidity of the area where the air conditioner is located from the server. Further, the humidity control information may be uploaded to the server when the air conditioner is turned on before (for example, when the air conditioner is turned on for the first time), the server stores the humidity control information in the database, and the humidity control information is directly fetched when the air conditioner is turned on every time later, so that the user is not required to upload the humidity control information every time.
S2, comparing the magnitude relation between the relative humidity and the preset humidity.
In this embodiment, the preset humidity is set according to the actual situation, which is not limited herein. In one embodiment, the predetermined humidity is 50%.
Referring to fig. 2, fig. 2 shows a specific embodiment after step S2, which is described in detail as follows:
S21: and if the relative humidity is greater than the preset humidity, starting a dehumidifying mode of the air conditioner.
In this embodiment, if the relative humidity is greater than the preset humidity, it indicates that the space where the air conditioner is located is relatively humid at this time, so the server controls the dehumidification mode of turning on the air conditioner.
S22: and acquiring an indoor temperature, and comparing the indoor temperature with a first preset temperature.
In this embodiment, after the dehumidification mode is turned on, it is necessary to further determine which mode to turn on to perform dehumidification according to the indoor temperature. The first preset temperature is set according to the actual situation, and is not limited herein. In one embodiment, the first predetermined temperature is 30 degrees celsius.
S23: and if the indoor temperature is higher than the first preset temperature, adjusting the opening of the electronic expansion valve and the rotating speed of the external fan so as to perform dehumidification treatment.
Referring to fig. 3, fig. 3 shows a specific embodiment of step S23, which is described in detail as follows:
s231: and if the indoor temperature is higher than the first preset temperature, acquiring the temperature of the heat exchanger of the outdoor unit.
S232: and calculating a value corresponding to the opening of the electronic expansion valve through a second preset formula based on the temperature of the heat exchanger of the outdoor unit, the indoor temperature and the first preset temperature to obtain the target opening of the electronic expansion valve.

The second preset formula is as follows: p 1＝K0+K1(T-T1)+K2T2;p1 is the opening degree of the target electronic expansion valve, K 0、K1、K2 is a constant, T is the indoor temperature, T 1 is the first preset temperature, and T 2 is the outdoor heat exchanger temperature.
In this embodiment, if the indoor temperature is greater than the first preset temperature, the temperature of the heat exchanger of the outdoor unit is obtained through the temperature sensing bulb, then a value corresponding to the opening of the electronic expansion valve is calculated through the second preset formula, so as to obtain a target opening of the electronic expansion valve, the rotation speed of the external fan is increased according to the preset value, so as to obtain a target rotation speed of the external fan, and finally the air conditioner performs dehumidification processing according to the target opening of the electronic expansion valve and the target rotation speed of the external fan.
The preset value is set according to the actual situation, and is not limited herein. In one embodiment, the predetermined value is 120.
S24: and if the indoor temperature is smaller than the first preset temperature, adjusting the operating frequency of the compressor to perform dehumidification treatment.
Referring to fig. 4, fig. 4 shows a specific embodiment of step S24, which is described in detail as follows:
s241: and if the indoor temperature is smaller than the first preset temperature, acquiring the temperature of the inner tube, the condensation temperature and the exhaust temperature of the compressor.
S242: the operating frequency of the compressor is calculated based on the inner tube temperature, the condensation temperature, and the discharge temperature.
S243: and when the temperature of the inner pipe is smaller than the second preset temperature, reducing the operating frequency of the compressor so as to perform dehumidification treatment.
S244: and when the temperature of the inner pipe is higher than a second preset temperature, increasing the operating frequency of the compressor so as to perform dehumidification treatment.
In this embodiment, if the indoor temperature is less than the first preset temperature, the inner tube temperature, the condensation temperature and the exhaust temperature of the compressor are obtained through the bulb. The operating frequency of the compressor is then calculated based on the inner tube temperature, the condensation temperature, and the discharge temperature. The calculation formula is as follows: p 2＝K3+K4T5+K5T3+K6T4,P2 is the operating frequency of the compressor, K 3、K4、K5、K6 is a constant, T 3 is the condensation temperature, T 4 is the exhaust temperature, and T 5 is the inner tube temperature. When the temperature of the inner pipe is smaller than a second preset temperature, the operation frequency of the compressor is reduced according to a preset reduction value so as to perform dehumidification treatment; and when the temperature of the inner pipe is higher than a second preset temperature, increasing the operating frequency of the compressor according to a preset increasing value so as to perform dehumidification treatment. It should be noted that the preset decrease value, the preset increase value, and the second preset temperature are set according to actual conditions, which are not limited herein.
And S3, if the relative humidity is smaller than the preset humidity, generating the indoor humidification amount of the air conditioner based on the relative humidity and the indoor volume, and performing humidification processing based on the indoor humidification amount.
In this embodiment, if the relative humidity is less than the preset humidity, it indicates that the space where the air conditioner is located is dry, and the air conditioner needs to be turned on to humidification mode. In this embodiment, humidification processing is performed with different indoor humidification amounts for different indoor volumes. In general, the larger the indoor volume, the more the indoor humidification amount.
Referring to fig. 5, fig. 5 shows a specific embodiment of step S3, which is described in detail as follows:
s31: and if the relative humidity is smaller than the preset humidity, acquiring the current air temperature and the current atmospheric pressure of the area where the air conditioner is located from the server.

Wherein, the preset formula is:
Where P is the atmospheric pressure, t is the current air temperature, ΔRH is the relative humidity, and ρ is the air density.
In this embodiment, since the server may call the current air temperature and the atmospheric pressure of the region where the air conditioner is located, the air conditioner may obtain the current air temperature and the atmospheric pressure of the region where the air conditioner is located from the server, and then calculate the air density of the space where the air conditioner is located through a preset formula.
Referring to fig. 6, fig. 6 shows a specific embodiment of step S33, which is described in detail as follows:
S331: the indoor volume is compared with a preset threshold.
In this embodiment, the indoor volume is compared with a preset threshold value, and it is determined in which threshold value the indoor volume is, and then a corresponding indoor humidification amount is generated for humidification processing. Wherein the preset threshold value comprises a first preset threshold value, a second preset threshold value and a third preset threshold value
S332: and if the indoor volume is within the first preset threshold, generating a first indoor humidification amount based on the air density and the indoor volume, and performing humidification processing based on the first indoor humidification.
S333: and if the indoor volume is within the second preset threshold, generating a second indoor humidification amount based on the air density and the indoor volume, and performing humidification treatment based on the second indoor humidification.
S334: and if the indoor volume is within a third preset threshold, generating a third indoor humidification amount based on the air density and the indoor volume, and performing humidification processing based on the third indoor humidification.
In this embodiment, it is assumed that the first preset threshold is (0, 45), the second preset threshold is (45, 90), the second preset threshold is (90, + -infinity ]; if the indoor volume is within the first preset threshold, the indoor humidification amount is 0.05vρ.ltoreq.m < 0.1vρ, where V is the indoor volume, ρ is the air density, if the indoor volume is within the second preset threshold, the indoor humidification amount is 0.15vρ.ltoreq.m < 0.2vρ, and if the indoor volume is within the third preset threshold, the indoor humidification amount is not less than 0.2vρ.
In the embodiment, the indoor volume of the space where the air conditioner is located and the relative humidity of the area where the air conditioner is located are obtained from a server; comparing the magnitude relation between the relative humidity and the preset humidity; and if the relative humidity is smaller than the preset humidity, generating the indoor humidification amount of the air conditioner based on the relative humidity and the indoor volume, and performing humidification processing based on the indoor humidification amount. According to the embodiment of the invention, based on the indoor volume and the relative humidity of the area where the air conditioner is located, the indoor humidity of the air conditioner is controlled, the humidity is collected without a humidity sensor, and the humidity control cost of the air conditioner is reduced; meanwhile, the humidification amount of the air conditioner is determined through the indoor volume, so that the condition that the humidification amount of the air conditioner is too large or too small is avoided, and the humidity control accuracy is improved.
Referring to fig. 7, fig. 7 is a flowchart illustrating another indoor humidity control method according to an embodiment of the invention. The indoor humidity control method provided by the embodiment of the invention is applied to a server. The indoor humidity control method provided by the embodiment of the invention comprises the steps S101-S104.

S103: and calculating the indoor volume of the space where the air conditioner is positioned according to the length and the width of the space and the floor height.
S104: and based on the area where the air conditioner is located, the current relative humidity is called, and the relative humidity of the area where the air conditioner is located is obtained.
S105: the indoor volume and the relative humidity of the area where the air conditioner is located are sent to the air conditioner.
In this embodiment, the room in which the air conditioner is located is identified in the house type map, so the server identifies the location in the house type map in which the air conditioner is located, that is, identifies the corresponding room, and then obtains the length and width of the corresponding room in the house type map. Because the humidity control information also comprises the floor height, the length, the width and the floor height are multiplied to obtain the indoor volume of the space where the air conditioner is located. Since the humidity control information also includes the region in which the air conditioner is located, the server can call the latest relative humidity of the region. For example, the air conditioner is located in Guangzhou white cloud, and the server may call the relative humidity reported by the Guangzhou white cloud on the same day. Since the humidity control information includes the region where the air conditioner is located, the server can call the current air temperature and the atmospheric pressure of the region. And finally, the server sends the indoor volume and the relative humidity of the area where the air conditioner is located to the air conditioner.
Further, the user can directly upload the indoor volume of the space where the air conditioner is located to the server. The server can directly identify the indoor volume in the humidity control information, and the calculation of the indoor volume is avoided.
