In the present application, an air conditioner performs a refrigeration cycle of the air conditioner by using a compressor, a condenser, an expansion valve, and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies refrigerant to the air that has been conditioned and heat-exchanged.
The compressor compresses a refrigerant gas in a high-temperature and high-pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.
The expansion valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state condensed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a cooling effect by heat-exchanging with a material to be cooled using latent heat of evaporation of a refrigerant. The air conditioner can adjust the temperature of the indoor space throughout the cycle.
The air conditioner includes an indoor unit and an outdoor unit, the outdoor unit being a part of a refrigeration cycle including a compressor and an outdoor heat exchanger, the indoor unit including an indoor heat exchanger, and an expansion valve may be provided in the indoor unit or the outdoor unit.
The indoor heat exchanger and the outdoor heat exchanger serve as a condenser or an evaporator. The air conditioner is used as a heater in a heating mode when the indoor heat exchanger is used as a condenser, and as a cooler in a cooling mode when the indoor heat exchanger is used as an evaporator.

The outdoor wind speed is converted into the pulse number, the relation between the pulse number and the real-time wind speed of the indoor fan is established, and the simulation rotating speed of the indoor fan is obtained according to the pulse number of the outdoor wind, so that the blowing rule of the indoor fan is the same as the blowing rule of the outdoor wind, and the outdoor natural blowing can be simulated only by a certain delay in time, the blowing experience of the outdoor environment is brought to the user, and the user experience is improved.
When the natural wind mode is started, the indoor fan rotates at a preset rotating speed, wherein the rotating speed can be constant or variable.

In step S2, the specific process of converting the wind speed of the outdoor wind within T seconds into the number of pulses is as follows:
the impeller is blown by outdoor wind to rotate, light emitted by the infrared irradiation lamp passes through the infrared through hole, when the impeller rotates, the impeller shading part rotates along with the impeller, the impeller root shading part generates shading action when passing through the infrared through hole, the shading action can be converted into a pulse signal, the pulse signal is fed back to the indoor control panel, and the indoor control panel records the pulse number of the impeller in T seconds. Outdoor wind speed is converted into impeller rotating speed, and the impeller rotating speed is further converted into pulse number, so that the outdoor wind is converted into the pulse number, and the relationship between the outdoor wind speed and the pulse number is established.

Specifically, in step S4, in the process of calculating the indoor fan simulated rotation speed, when the rotation speed value corresponding to the Ns rear pulse number is greater than the fan simulated rotation speed maximum value, the rotation speed value corresponding to the pulse number is the fan simulated rotation speed maximum value, and when the rotation speed value corresponding to the Ns rear pulse number is less than the fan simulated rotation speed minimum value, the rotation speed value corresponding to the pulse number is the fan simulated rotation speed minimum value. The simulation rotating speed of the indoor fan is limited between the maximum value and the minimum value of the rotating speed of the indoor fan, and the situation that disturbance is brought to the indoor environment due to overhigh or overlow outdoor wind speed to influence user experience is avoided.
Specifically, in step S5, the pulse number of the outdoor air continues to be acquired for a time when M is less than or equal to the current time, so that it can be ensured that the pulse number has been acquired M seconds before the current time, an effective indoor fan simulation rotation speed can be obtained, and the current indoor fan rotation speed is set to be the indoor fan simulation rotation speed M seconds before the current time, so that experience delay of M seconds between the air blown by the indoor fan and the outdoor air exists.

s33: the maximum value of the pulse number is matched with the maximum value of the simulation rotating speed of the indoor fan, the minimum value of the pulse number is matched with the minimum value of the simulation rotating speed of the indoor fan, and the functional relation between the simulation rotating speed of the indoor fan and the pulse number is established.
When the indoor fan can simulate natural wind, the maximum value and the minimum value of the simulation rotating speed of the indoor fan are changed according to user requirements and environment states, the simulation rotating speed of the indoor fan is changed, the requirements of different users on wind strength are met, the influence of the external severe environment on the indoor environment can be avoided, and user experience is improved.
The output intensity adjustment may also be set between step S4 and step S5, and referring to fig. 4, the specific steps are:
and judging whether output intensity adjustment is carried out or not, if not, executing S5, if so, determining an output intensity coefficient K, wherein K is more than or equal to 0 and less than or equal to 1, obtaining a new change relation between the indoor fan simulation rotating speed and time according to the change relation between the indoor fan simulation rotating speed and the time, and then executing S5.
When the indoor fan can simulate natural wind, the simulation rotating speed of the indoor fan is directly changed according to user demands and environmental conditions, the demands of different users on wind intensity are met, the influence of external severe environment on the indoor environment can be avoided, and user experience is improved.

For example, as shown in fig. 7, taking K as 0.5, the indoor fan simulated rotation speed versus time in fig. 8 is obtained according to the indoor fan simulated rotation speed versus time in fig. 7, so that the fan simulated rotation speed is 50% output.
