A control method of a synchronous multi-airconditioner according to an embodiment of the present invention will be described with reference to fig. 1 to 3. It should be noted that the step numbers in the present application, such as S1, S2, S3, S4, and the like, are only for convenience of describing the present solution, and are not to be construed as limiting the order of the steps. That is, the execution order of, for example, steps S1, S2, S3, S4, etc. may be specifically determined according to actual needs, and is not limited to the control in the order of steps in the following embodiments.
In some embodiments of the present invention, as shown in fig. 1, a flowchart of a control method for synchronizing a multi-split air conditioner according to an embodiment of the present invention is provided, wherein the control method at least includes steps S1-S4, which are described as follows.
And S1, acquiring the indoor environment temperature of each indoor unit.
The temperature acquisition module, such as a temperature sensor, can be arranged to detect the indoor ambient temperature, and the temperature sensor can be arranged on the indoor unit.
In an embodiment, the temperature at the air inlet of each indoor unit may be obtained as the indoor ambient temperature, for example, a temperature sensor is provided at the air inlet of each indoor unit to detect the temperature of the air at the air inlet of each indoor unit.
Alternatively, the temperature of the indoor heat exchanger of each indoor unit is acquired as the indoor ambient temperature, and for example, a temperature sensor is provided on the indoor heat exchanger of each indoor unit to detect the temperature of the indoor heat exchanger of each indoor unit.
Or, the difference between the indoor set temperature and the indoor detected temperature of each indoor unit can be obtained. For example, the indoor set temperature of each indoor unit in the current operation mode is obtained, wherein the operation modes of the indoor units in the synchronous multi-split air conditioner are the same and the indoor set temperatures are the same, and the operation modes of the indoor units are the same and the indoor set temperatures are the same. And taking the temperature of the air at the air inlet of each indoor unit or the temperature of the indoor heat exchanger of each indoor unit as the indoor environment temperature, and subtracting the obtained indoor set temperature from the indoor environment temperature detected by each temperature sensor to obtain the difference value between the indoor set temperature and the indoor detected temperature of each indoor unit.
In a cooling mode or a heating mode, if the temperature acquisition module is directly arranged in the indoor heat exchanger of each indoor unit, the acquired indoor environment temperature is actually the temperature of the indoor heat exchanger of each indoor unit, and the temperature of the indoor heat exchanger is a parameter of the air conditioner in the operation process, which is related to the operation state of the air conditioner, and cannot be directly perceived by a user. If the difference between the indoor set temperature and the indoor detected temperature of each indoor unit is obtained, the obtained temperature difference is a process calculated amount and cannot be directly sensed by a user. Because in the cooling mode or the heating mode, the purpose of the user using the air conditioner is mainly to adjust the indoor environment temperature, preferably, a mode of acquiring the temperature at the air inlet of each indoor unit as the indoor environment temperature can be adopted, and the temperature at the air inlet of each indoor unit in the mode, namely the temperature of the air entering the indoor unit, can be directly sensed by the user and is more direct and effective.
S2, a highest indoor ambient temperature and a lowest indoor ambient temperature among the plurality of indoor ambient temperatures are obtained.
Taking the temperature at the air inlet of each indoor unit as an example of the indoor ambient temperature, the obtained indoor ambient temperatures of the indoor units are compared to screen out the highest indoor ambient temperature and the lowest indoor ambient temperature, for example, the highest indoor ambient temperature and the lowest indoor ambient temperature can be respectively represented by T1 and T2.
In the cooling mode or the heating mode, the cooling or heating effect of the corresponding indoor unit can be judged according to the acquired maximum indoor environment temperature T1 and the acquired minimum indoor environment temperature T2. Specifically, in the cooling mode, the temperature at the air inlet of the indoor unit is low, which indicates that the indoor heat load is small, the cooling effect of the indoor unit corresponding to the lowest indoor environment temperature T2 is the best, and the temperature at the air inlet of the indoor unit is high, which indicates that the indoor heat load is large, and the cooling effect of the indoor unit corresponding to the highest indoor environment temperature T1 is the worst. In the heating mode, the temperature at the air inlet of the indoor unit is high, which means that the indoor heat load is small, the heating effect of the indoor unit corresponding to the highest indoor environment temperature T1 is the best, and the temperature at the air inlet of the indoor unit is low, which means that the indoor heat load is large, and the cooling effect of the indoor unit corresponding to the lowest indoor environment temperature T2 is the worst.
And S3, determining a first target indoor fan according to the highest indoor environment temperature and determining a second target indoor fan according to the lowest indoor environment temperature.
The indoor unit fan corresponding to the highest indoor environment temperature T1 is determined to be a first target indoor fan, and the indoor unit fan corresponding to the lowest indoor environment temperature T2 is determined to be a second target indoor fan.
And S4, determining that the temperature difference between the highest indoor environment temperature and the lowest indoor environment temperature is greater than or equal to a temperature difference threshold value, and adjusting the rotating speeds of the first target indoor fan and the second target indoor fan according to the current operation mode.
The temperature difference threshold can be set according to the requirement or under the laboratory condition, for example, the temperature difference threshold is set to be 2 ℃ but not limited to 2 ℃, and can be any value such as 3 ℃, 5 ℃, 6 ℃ or 10 ℃ and the like. Subtracting the highest indoor environment temperature T1 from the lowest indoor environment temperature T2 to obtain a temperature difference between the highest indoor environment temperature T1 and the lowest indoor environment temperature T2, if the highest indoor environment temperature T1 is closer to the lowest indoor environment temperature T2, it indicates that the cooling or heating effects of the indoor units are close, if the difference between the highest indoor environment temperature T1 and the lowest indoor environment temperature T2 is large, and the temperature difference between the highest indoor environment temperature T1 and the lowest indoor environment temperature T2 is greater than or equal to a temperature difference threshold, it indicates that the outlet air temperatures of the indoor units are uneven, i.e., the difference between the cooling or heating effects is large, and the refrigerant amount distributed to the indoor units is uneven, the outlet air temperature of each indoor unit and the refrigerant amount distributed to the corresponding indoor unit need to be adjusted.
Specifically, the rotating speeds of the first target indoor fan and the second target indoor fan can be adjusted by adjusting the current operation mode, so that the refrigerant quantity distributed to the first target indoor fan and the second target indoor fan is adjusted, and the air outlet temperature of each indoor unit is controlled to be uniform. For example, in the cooling mode, the first target indoor fan speed is controlled to be increased, the second target indoor fan speed is controlled to be decreased, the cooling capacity of the indoor unit corresponding to the highest indoor environment temperature T1 is increased, the second target indoor fan speed is controlled to be decreased, and the cooling capacity of the indoor unit corresponding to the lowest indoor environment temperature T2 is weakened, so that the indoor environment temperature is uniformly decreased. Or, in the heating mode, the rotating speed of the first target indoor fan is controlled to be reduced, the heating capacity of the indoor unit with the highest indoor environment temperature T1 is weakened, the rotating speed of the second target indoor fan is controlled to be increased, and the heating capacity of the indoor unit with the lowest indoor environment temperature T2 is improved, so that the indoor environment temperature is controlled to be uniformly increased, the distribution work of the air conditioner for self-adaptive adjustment of the refrigerant quantity can be influenced by adjusting the air outlet temperature of each indoor unit, an indoor unit refrigerant adjusting device does not need to be arranged, and the user experience is guaranteed.
According to the control method of the synchronous one-driving-multiple air conditioner, the indoor environment temperature of each indoor unit is obtained to judge the refrigerating or heating effect of the corresponding indoor unit, the highest indoor environment temperature and the lowest indoor environment temperature in the multiple indoor environment temperatures and the temperature difference value of the two temperature maxima are obtained, the rotating speed of the fan of the indoor unit corresponding to the highest indoor environment temperature and the fan of the indoor unit corresponding to the lowest indoor environment temperature are adjusted according to the temperature difference value, so that the temperature of the two indoor units with larger refrigerating or heating effect difference can be adjusted, the air outlet temperature of each indoor unit is controlled to be uniform, the refrigerating or heating effect of each indoor unit is ensured to be close, the air outlet temperature of each indoor unit is adjusted to influence the distribution work of the air conditioner for adaptively adjusting the refrigerant quantity, an indoor unit refrigerant adjusting device is not needed, and the cost is lower, and the user experience is guaranteed.
In some embodiments of the present invention, as shown in fig. 2, a flowchart of a control method for synchronizing a multi-split air conditioner according to another embodiment of the present invention is shown, wherein the rotation speed adjusting step may include step S41, which is described as follows.
And S41, controlling the rotating speed of the first target indoor fan to increase the first rotating speed threshold value and controlling the rotating speed of the second target indoor fan to decrease the second rotating speed threshold value when the current operation mode is the cooling mode.
The first rotation speed threshold and the second rotation speed threshold may be set according to needs or under laboratory conditions, for example, the first rotation speed threshold and the second rotation speed threshold are both set to 10% but not limited to 10%, and may be any percentage value such as 15%, 20%, 30%, or 60%.
Specifically, in the cooling mode, when it is determined that the temperature difference between the highest indoor environment temperature T1 and the lowest indoor environment temperature T2 is greater than or equal to the temperature difference threshold, it indicates that the indoor unit corresponding to the highest indoor environment temperature T1 has the worst cooling effect, and the indoor unit corresponding to the lowest indoor environment temperature T2 has the best cooling effect, the first target indoor fan rotation speed is controlled to increase the first rotation speed threshold so as to increase the cooling capacity of the indoor unit, and the second target indoor fan rotation speed is controlled to decrease the second rotation speed threshold so as to decrease the cooling capacity of the indoor unit, so that the cooling effects of the two indoor units are reduced, the indoor environment temperatures are controlled to be uniformly decreased, and the user experience is guaranteed.
In some embodiments of the present invention, as shown in fig. 2, the rotation speed adjusting step may further include step S42, which is described as follows.
And S42, controlling the rotating speed of the second target indoor fan to increase the third rotating speed threshold value and controlling the rotating speed of the first target indoor fan to decrease the fourth rotating speed threshold value when the current operation mode is the heating mode.
The third rotation speed threshold and the fourth rotation speed threshold may be set according to needs or under laboratory conditions, for example, the third rotation speed threshold and the fourth rotation speed threshold are both set to 10% but not limited to 10%, and may be any percentage value, such as 15%, 20%, 30%, or 60%.
Specifically, in the heating mode, when it is determined that the temperature difference between the highest indoor environment temperature T1 and the lowest indoor environment temperature T2 is greater than or equal to the temperature difference threshold, it indicates that the heating effect of the indoor unit corresponding to the highest indoor environment temperature T1 is the best, and the cooling effect of the indoor unit corresponding to the lowest indoor environment temperature T2 is the worst, the first target indoor fan rotation speed is controlled to decrease the fourth rotation speed threshold to decrease the heating capability of the indoor unit, and the second target indoor fan rotation speed is controlled to increase the third rotation speed threshold to increase the heating capability of the indoor unit, decrease the heating effects of the two indoor units, control the indoor environment temperatures to increase uniformly, and ensure the user experience.
In other embodiments of the present invention, if the temperature difference between the highest indoor ambient temperature T1 and the lowest indoor ambient temperature T2 is smaller than the temperature difference threshold, it is determined that the highest indoor ambient temperature T1 is closer to the lowest indoor ambient temperature T2, and the cooling or heating effects of the two corresponding indoor units are closer, and it is not necessary to adjust the rotation speed of the indoor fan of each indoor unit.
