no. 1 example

[0045] Based on this problem, an embodiment of the present invention provides an air conditioner dehumidification method. see figure 1 , the air-conditioning dehumidification method includes, for example:

[0046] Step S1: Obtain the indoor relative humidity RH, and determine whether the indoor relative humidity RH satisfies the adjustment condition of the internal fan;

[0047] Step S2: If the adjustment condition of the indoor fan is met, then determine the initial wind gear of the indoor fan 222, and adjust the speed of the indoor fan 222 on the basis of the initial wind gear, and control the dehumidification capacity of the indoor unit 220.

[0048] It should be noted that the dehumidification method of the air conditioner is carried out in cooling mode or dehumidification mode, and the indoor fan 222 is controlled according to the indoor relative humidity RH to adjust the dehumidification capacity of the indoor unit 220, so that the indoor relative humidity RH Adjust to...

Abstract

The invention provides an air conditioner dehumidification method and device and an air conditioner. The air conditioner dehumidification method comprises the steps that the indoor relative humidity RH is obtained, and whether the indoor relative humidity RH meets an inner fan adjusting condition or not is judged; and if the inner fan adjusting condition is met, the initial air gear of an inner fan is determined, the rotating speed n of the inner fan is adjusted on the basis of the initial air gear, and the dehumidification amount of an indoor unit is controlled, wherein the inner fan adjusting condition comprises the steps that the size relation between the indoor relative humidity RH and a first humidity threshold RH1 and the size relation between the indoor relative humidity RH and a second humidity threshold RH2 are judged, and the rotating speed n of the inner fan is correspondingly adjusted. According to the embodiment of the invention, the problem that the air conditioner cannot adjust the rotating speed of the inner fan according to the current humidity so as to control the indoor humidity is solved.

Description

technical field [0001] The invention relates to the technical field of air conditioner control, in particular to an air conditioner dehumidification method, an air conditioner dehumidification device and an air conditioner. Background technique [0002] When the relative humidity is > 65% or < 38%, the germs in the air breed the fastest, and when 45% ≤ relative humidity ≤ 55%, the mortality rate of the germs in the air is higher, so keep the relative humidity in the room in an appropriate range, Beneficial to the human body. The humidity in the air environment in summer is relatively high, and the relative humidity is relatively high. Dehumidification through the air conditioner is currently a mainstream method. When the temperature of the evaporator tube of the indoor unit is lower than the air dew point temperature, the water vapor in the air will evaporate. The liquefaction on the tube wall of the device turns into water drops, and condensed water is produced to ac...
