The 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 outdoor unit of the air conditioner refers to a portion of a refrigeration cycle including a compressor and an outdoor heat exchanger, the indoor unit of the air conditioner includes 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. When the indoor heat exchanger is used as a condenser, the air conditioner is used as a heater in a heating mode, and when the indoor heat exchanger is used as an evaporator, the air conditioner is used as a cooler in a cooling mode.
Fig. 1 shows a circuit configuration of an air conditioner 1, and the air conditioner 1 includes a refrigerant circuit 10, and is capable of executing a vapor compression refrigeration cycle by circulating a refrigerant in the refrigerant circuit 10. The indoor unit 3 and the outdoor unit 2 are connected by a connecting pipe 4 to form a refrigerant circuit 10 in which a refrigerant circulates. The refrigerant circuit 10 includes a compressor 11, an outdoor heat exchanger 13, an expansion valve 14, an accumulator 15, and an indoor heat exchanger 16. Among them, the indoor heat exchanger 16 and the outdoor heat exchanger 13 operate as a condenser or an evaporator. The compressor 11 sucks the refrigerant from the suction port, and discharges the refrigerant compressed therein to the indoor heat exchanger 16 from the discharge port. The compressor 11 is an inverter compressor with variable capacity that performs rotational speed control by an inverter, and the four-way valve 12 switches between heating and cooling.
The outdoor heat exchanger 13 has a first inlet and a second outlet for allowing the refrigerant to flow between the refrigerant and the suction port of the compressor 11 through the accumulator 15, and the refrigerant flows between the refrigerant and the expansion valve 14. The outdoor heat exchanger 13 exchanges heat between the outdoor air and the refrigerant flowing through a heat transfer pipe (not shown) connected between the second inlet and the first inlet of the outdoor heat exchanger 13.
The expansion valve 14 is disposed between the outdoor heat exchanger 13 and the indoor heat exchanger 16. The expansion valve 14 has a function of expanding and decompressing the refrigerant flowing between the outdoor heat exchanger 13 and the indoor heat exchanger 16. The expansion valve 14 is configured to be capable of changing the opening degree, and by decreasing the opening degree, the flow path resistance of the refrigerant passing through the expansion valve 14 is increased, and by increasing the opening degree, the flow path resistance of the refrigerant passing through the expansion valve 14 is decreased. The expansion valve 14 expands and decompresses the refrigerant flowing from the indoor heat exchanger 16 to the outdoor heat exchanger 13 during the heating operation. Further, even if the states of other devices installed in the refrigerant circuit 10 do not change, when the opening degree of the expansion valve 14 changes, the flow rate of the refrigerant flowing in the refrigerant circuit 10 changes.
The indoor heat exchanger 16 has a second inlet and outlet for allowing the liquid refrigerant to flow between the expansion valve 14 and the indoor heat exchanger, and has a first inlet and outlet for allowing the gas refrigerant to flow between the compressor 11 and the discharge port. The indoor heat exchanger 16 exchanges heat between the refrigerant flowing through the heat transfer pipe connected between the second inlet and the first inlet and the second outlet of the indoor heat exchanger 16 and the indoor air.
An accumulator 15 is disposed between the outdoor heat exchanger 13 and the suction port of the compressor 11. In the accumulator 15, the refrigerant flowing from the outdoor heat exchanger 13 to the compressor 11 is separated into a gas refrigerant and a liquid refrigerant. Then, the gas refrigerant is mainly supplied from the accumulator 15 to the suction port of the compressor 11.
The outdoor unit 2 further includes an outdoor fan 21, and the outdoor fan 21 generates an airflow of outdoor air passing through the outdoor heat exchanger 13 to promote heat exchange between the refrigerant flowing through the heat transfer tubes and the outdoor air. The outdoor fan 21 is driven by an outdoor fan motor 21A capable of changing the rotation speed. The indoor unit 3 further includes an indoor fan 31, and the indoor fan 31 generates an airflow of the indoor air passing through the indoor heat exchanger 16 to promote heat exchange between the refrigerant flowing through the heat transfer tubes and the indoor air. The indoor fan 31 is driven by an indoor fan motor 31A whose rotation speed can be changed.
As described in the background art, in the prior art, the purifier automatically starts to cause the noise of the whole air conditioner to suddenly increase, which affects the user experience.
To solve the above problem, an air conditioner according to an embodiment of the present invention includes a refrigerant circulation circuit, a compressor, an outdoor heat exchanger, an indoor fan, a purifier, and a controller, wherein the controller is configured to:

The current accumulated maximum wind speed is determined according to the current wind speed of the indoor fan and the self-starting target wind speed of the purification fan, wherein the self-starting target wind speed is the target wind speed when the preset noise function is in a closed state and the purifier is self-started, and the self-starting target wind speed is larger than the preset minimum wind speed.
In order to determine an accurate current accumulated maximum wind speed, in a preferred embodiment of the present application, the controller is further configured to:

if the current wind speed is not less than the self-starting target wind speed, determining the self-starting target wind speed as the current accumulated highest wind speed;
and if the current wind speed is less than the self-starting target wind speed, determining the current wind speed as the current accumulated highest wind speed.
As described above, the current wind speed and the self-starting target wind speed are compared, and the smaller one of the current wind speed and the self-starting target wind speed is determined as the current accumulated highest wind speed, so that the purification effect of the purifier is ensured, and the control degree of the noise generated after the normal operation of the purifier is matched with the operation state of the current air conditioner. If the current accumulated highest wind speed is smaller current wind speed, noise generated by the whole air conditioner cannot be obviously increased after the wind speed of the purifier is increased, and therefore the influence degree on a user is reduced to the minimum.

The controller also writes the opening instruction into the electrified erasable programmable read-only memory for setting and storing, so that the air conditioner is executed according to the last stored opening instruction after being powered off and electrified again. The air conditioner can be defaulted to start a preset noise control function when leaving a factory.
