In the set wind state, the rotational flow wind dispersing module is positioned at a wind shielding position. The wind shielding position specifically refers to a position where the cyclone wind dispersing module partially shields or completely shields the air outlet. Specifically, when the air conditioner further comprises a second air deflector arranged at the lower side of the air outlet, the wind shielding position specifically refers to the position where the cyclone wind dispersing module is matched with the second air deflector to shield the air outlet, and the air conditioner can specifically comprise the position where the cyclone wind dispersing module is abutted to the air deflector and completely shields the air outlet, and the position where the cyclone wind dispersing module is arranged at intervals with the air deflector and partially shields the air outlet. When the air deflector and the cyclone air dispersing module are positioned at the matched wind shielding position, one part of air outlet of the air conditioner is dispersed from the cyclone air dispersing module and then blown out, and the other part is dispersed from a plurality of ventilation holes of the air deflector and then blown out.
Specifically, in this embodiment, when the air conditioner is in the cooling operation, if a set wind sensing instruction (such as an instruction for reducing wind sensing, an instruction without wind sensing, or an instruction with soft wind sensing) is received, the air deflector and the cyclone wind dispersing module are controlled to move to a wind shielding position, and the air conditioner is in the set wind outlet state when the air deflector is located at the wind shielding position; the wind shielding position is a position where the lower end of the cyclone wind dispersing module is abutted to the wind deflector and is matched with the wind deflector to seal the air outlet, that is to say, the wind deflector is matched with the cyclone wind dispersing module to completely shield the air outlet, part of air flow in the air duct is blown out from the cyclone wind dispersing module, and the rest of air flow is scattered and blown out from the vent hole of the wind deflector.

In addition, when the air conditioner is in refrigeration operation, if a set wind sense instruction is not received, the rotational flow wind dispersing module can move to a position of completely opening the air outlet, and the air outlet of the air outlet is not blocked.

The condensation condition can be specifically determined based on a first temperature condition and a first humidity condition which are required to be reached by the environment when the condensation occurs at the air outlet, and the condensation condition is specifically a temperature and humidity condition which does not reach the first temperature condition and the first humidity condition but is close to the first temperature condition and the first humidity condition. Specifically, for example, when the minimum humidity value M required by the environment is reached when the air outlet is exposed, the exposure condition may include M-a; for another example, when the temperature change parameter required to be reached by the environment when the air outlet is exposed is N, the exposure condition can comprise N-b; the humidity change parameter required to be achieved by the environment when the air outlet is exposed is P, and the exposure condition can comprise P-c and the like.

When the temperature characteristic parameter and the humidity characteristic parameter reach condensation conditions, the evaporation temperature of the air conditioner is changed by adjusting an electronic expansion valve of the air conditioner, and meanwhile, the latent heat of the air conditioner is reduced by adjusting the rotating speed of a fan of the air conditioner.
The latent heat quantity refers specifically to the amount of heat absorbed or released by the indoor air per unit mass of substance or by each mole of substance during a phase change. Per mass of substance or with heat absorbed or released per mole of substance during phase change. The occurrence of latent heat is always accompanied by the change of the phase state of the substance, and on the basis of the change of the phase state of the substance can be avoided by the reduction of the amount of latent heat, and the phase change of gaseous water vapor into condensed water at the air outlet can be avoided.
The specific adjustment modes of the electronic expansion valve and the fan can be set according to the positions of the electronic expansion valve and the fan, and the adjustment modes can be different if the positions are different, and only the determined adjustment modes are required to reduce the latent heat of the air conditioner.
In the embodiment of the invention, the electronic expansion valve is arranged at the inlet of the indoor heat exchanger of the air conditioner, and based on the electronic expansion valve, the opening degree can be reduced to reduce the latent heat. The opening of the electronic expansion valve can be adjusted based on preset adjusting parameters, and corresponding adjusting parameters can be determined based on the actual working condition of the air conditioner to adjust. The adjusting parameters of the electronic expansion valve specifically comprise adjusting amplitude, adjusting speed, adjusting duration and the like. For example, the adjustment parameters (such as adjustment amplitude, adjustment rate, etc.) of the opening degree of the electronic expansion valve may be determined based on the deviation amounts of the current temperature characteristic parameter and the humidity characteristic parameter from the corresponding parameters in the condensation condition, and the electronic expansion valve is controlled to reduce the opening degree at the current opening degree according to the determined adjustment parameters.
Further, the fans may include, in particular, indoor fans and/or outdoor fans. When the fan comprises an indoor fan, the reduction of the latent heat can be realized by controlling the indoor fan to reduce the rotating speed; when the fan comprises an outdoor fan, the rotation speed of the outdoor fan can be controlled to be increased to reduce the latent heat; when the fan comprises an indoor fan and an outdoor fan, the indoor fan can be controlled to reduce the rotating speed, and the outdoor fan is controlled to increase the rotating speed so as to reduce the latent heat. The rotating speed of the fan can be adjusted based on preset adjusting parameters, and corresponding adjusting parameters can be determined to be adjusted based on the actual working condition of the air conditioner. The adjusting parameters of the fan rotation speed comprise adjusting amplitude, adjusting speed, adjusting duration and the like. For example, the adjustment parameters (e.g., adjustment amplitude, adjustment rate, etc.) for the fan speed may be determined based on the current temperature and humidity characteristic parameters and the amount of deviation of the corresponding parameters in the condensation conditions. Specifically, when the rotation speeds of the indoor fan and the outdoor fan need to be adjusted, the adjustment amplitude or the adjustment speed of the speed reduction of the indoor fan can be determined based on the deviation amount, and the rotation speed of the outdoor fan is increased according to the same adjustment amplitude and adjustment speed of the indoor fan.
