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.
To further describe aspects of the present application, in an example of the present application, the air conditioner includes:
the refrigerant circulation loop circulates the refrigerant in a loop formed by the compressor, the condenser, the expansion valve, the evaporator, the four-way valve and the pressure reducer;
the compressor is used for compressing low-temperature and low-pressure refrigerant gas into high-temperature and high-pressure refrigerant gas and discharging the high-temperature and high-pressure refrigerant gas to the condenser;
one of the outdoor heat exchanger and the indoor heat exchanger works for the condenser, and the other works for the evaporator;

If the rotating speed of the fresh air fan is too large, the noise of the air conditioner complete machine is too large, and the use experience of a user is influenced, so that when the air conditioner and the fresh air fan operate simultaneously, the rotating speed of the fresh air fan is adjusted to be very important.
In the preferred embodiment of this application, at first acquire the air conditioner noise when the air conditioner opens alone, then acquire the new trend noise when the new trend fan opens alone, air conditioner noise and new trend noise sum are the final noise when air conditioner and new trend fan open simultaneously, judge whether air conditioner noise and new trend noise sum are greater than the noise threshold value of predetermineeing, if be greater than the noise threshold value, it is too big to explain the noise this moment, user's experience has been influenced, so adjust the rotational speed of new trend fan, until air conditioner noise and new trend noise sum is less than or equal to the noise threshold value of predetermineeing, certain new trend amount of wind has both been guaranteed this moment, it can not reach the degree that influences user's use experience also to have guaranteed final noise, new trend amount of wind and noise have been taken.
To capture the air conditioning noise and the fresh air noise, in some embodiments, the controller is further configured to:
when the air conditioner is independently started, collecting air conditioning air volume and air conditioning noise at different air conditioning rotating speeds, and generating a corresponding relation formula of the air conditioning rotating speed and the air conditioning air volume and a corresponding relation formula of the air conditioning rotating speed and the air conditioning noise;
when the fresh air fan is independently started, collecting fresh air volume and fresh air noise at different fresh air rotating speeds, and generating a corresponding relation formula of the fresh air rotating speed and the fresh air volume and a corresponding relation formula of the fresh air rotating speed and the fresh air noise.
In the preferred embodiment of this application, need gather air conditioner noise when the air conditioner is opened alone and new trend noise when the new trend fan is opened alone, but air conditioner noise and new trend noise can't directly be acquireed, so we need acquire through air conditioner rotational speed and new trend fan rotational speed, at first after opening the air conditioner, gather the air conditioning amount of wind under the different air conditioner rotational speeds and the air conditioner noise, under each air conditioner rotational speed, all can correspond an air conditioning amount of wind and air conditioner noise, according to the data that gathers we can establish the corresponding relation formula of air conditioner rotational speed and air conditioning amount of wind, the same corresponding relation formula that also can obtain air conditioner rotational speed and air conditioner noise. The same steps are applied, after the fresh air fans are independently opened, the fresh air volume and the fresh air noise under different fresh air rotating speeds are collected, under each fresh air fan rotating speed, a fresh air volume and a fresh air noise can be corresponding, a corresponding relation formula of the fresh air rotating speed and the fresh air volume can be established according to collected data, and a corresponding relation formula of the fresh air rotating speed and the fresh air noise can be obtained similarly.

and determining the current fresh air speed and the current fresh air noise based on the current fresh air volume, the corresponding relation formula of the fresh air rotating speed and the fresh air volume and the corresponding relation formula of the fresh air rotating speed and the fresh air noise.
In the preferred embodiment of the application, when the air conditioner is started and the fresh air fan is automatic air, the air conditioner rotating speed at the moment is collected, and the current air conditioner air volume and the current air conditioner noise can be obtained according to the air conditioner rotating speed at the moment, the corresponding relation formula of the air conditioner rotating speed and the air conditioner air volume and the corresponding relation formula of the air conditioner rotating speed and the air conditioner noise.
After the current air conditioning air volume is obtained, a new air volume interval corresponding to the current air conditioning air volume can be obtained, because the new air volume interval is a new air volume value within a certain range, the maximum value in the new air volume interval is taken as the current new air volume, and after the current new air volume is obtained, the current new air speed and the current new air noise can be determined based on a corresponding relation formula of the new air rotating speed and the new air volume and a corresponding relation formula of the new air rotating speed and the new air noise.
In order to adjust the rotation speed of the fresh air fan, in some embodiments, the controller is specifically configured to:
when the sum of the current air conditioner noise and the current fresh air noise is not greater than the preset noise threshold value, the air conditioner operates at the current fresh air rotating speed;
and when the sum of the current air conditioner noise and the current fresh air noise is greater than the preset noise threshold value, taking the fresh air volume obtained by subtracting a preset air volume value from the current fresh air volume as the current fresh air volume until the sum of the current air conditioner noise and the current fresh air noise is not greater than the preset noise threshold value.
In the preferred embodiment of the present application, after the current air conditioner noise and the current fresh air noise are acquired, comparing the sum of the current air conditioner noise and the current fresh air noise with a preset noise threshold value, if the sum of the current air conditioner noise and the current fresh air noise is not more than the preset noise threshold value, the rotating speed of the fresh air is proper at the moment, adjustment is not needed, if the sum of the current air conditioner noise and the current fresh air noise is larger than a preset noise threshold value, the noise at this time is too large, which affects the user experience, the fresh air rotating speed of the fresh air fan needs to be adjusted, the fresh air quantity obtained by subtracting the preset air quantity value from the current fresh air quantity is used as the current fresh air quantity, and then continuously judging whether the sum of the adjusted air conditioner noise and the fresh air noise is greater than a preset noise threshold value, and if so, continuously adjusting until the sum of the air conditioner noise and the fresh air noise is not greater than the preset noise threshold value.
