Description
Technical Field
The invention relates to the technical field of air conditioners, in particular to a method and a device for controlling a fan of an air conditioner indoor unit, an air conditioner and a storage medium.
Background
In the refrigeration engineering, some hose air channels are very long, so that the resistance is greatly increased, the static pressure of the fan needs to be adjusted, and the rotation speed of the fan is adjusted to be high, so that cold air/hot air can be blown out. Otherwise, the blown air is gathered in the air duct, although the temperature of the air duct is preferred, the indoor air is not really circulated, and the effect is not good. Currently, the same model is defaulted to have the same static pressure when the internal machine is shipped from the factory, depending on the model. Although after-sales service personnel can carry out dial adjustment according to the length of the air duct, the adjustable static pressure range is single. And each internal machine needs manual adjustment, which wastes time and labor, and the air pipes of each internal machine are different in length and different in required static pressure, so that the static pressure of the internal machine can not be adjusted uniformly and accurately enough.
Disclosure of Invention
The invention aims to provide a control method of a fan of an air conditioner internal unit, which aims to solve the technical problem that the method is difficult to adapt to different lengths of air pipes.
In order to solve the technical problems, the invention provides a method for controlling a fan of an air conditioner internal unit, which comprises the following steps:
acquiring indoor environment temperature, indoor unit coil pipe temperature, indoor set temperature and continuous operation time;
and if the absolute value of the first deviation between the indoor environment temperature and the indoor set temperature is greater than a first preset temperature difference, the absolute value of the second deviation between the indoor environment temperature and the indoor unit coil pipe temperature is greater than a second preset temperature difference, and the continuous operation time is greater than the preset operation time, controlling the inner unit fan to increase the rotating speed.
The method for controlling the fan of the air conditioner internal unit has the advantages that:
if the capacity of the indoor unit of the air conditioner is insufficient, the indoor unit does not reach the preset temperature within the normal time, and the room temperature is small in change, namely the difference between the indoor environment temperature and the indoor set temperature is large. Specifically, if the indoor environment temperature is significantly higher than the indoor set temperature and is maintained for a certain time in the cooling mode, the indoor environment temperature obviously does not reach the cooling temperature, or if the indoor environment temperature is significantly lower than the indoor set temperature and is maintained for a certain time in the heating mode, the indoor environment temperature obviously does not reach the heating temperature. Moreover, if the difference between the indoor environment temperature and the indoor unit coil pipe temperature is large, the pipe temperature preference is shown, the situation that the indoor set temperature cannot be achieved in the refrigerating mode is not caused by the fact that the indoor unit coil pipe temperature is too high, and the situation that the indoor set temperature cannot be achieved in the heating mode is not caused by the fact that the indoor unit coil pipe temperature is too low is solved, so that the air quantity can be increased on an indoor unit fan, the air supply capacity can be improved, and the cold quantity or the heat quantity of the indoor unit coil pipe can be conveyed to the indoor space to change the indoor environment temperature.
Therefore, for each indoor unit, the rotating speed of the indoor unit fan suitable for the indoor unit can be found in a self-adaptive mode, the condition that the static pressure loss amount of each indoor unit is different due to different air channel lengths is avoided, different rotating speeds are matched for corresponding static pressure losses independently, the complexity of manual adjustment is reduced, and the adaptability of the multi-connected air conditioner to the static pressure air quantity is improved.
In the preferred technical scheme, the method further comprises the steps of obtaining an actual current value of the inner fan and an actual rotating speed of the inner fan, and increasing the rotating speed of the inner fan if the actual current value is larger than a preset current value, wherein the preset current value is a current value of a set static pressure output by the inner fan at the actual rotating speed.
Under the condition that the model selection is normal, after the unit stably operates, the indoor environment temperature approaches the indoor set temperature. If the deviation between the indoor environment temperature and the indoor set temperature is large, the model selection is not enough, or the air circulation of the inner fan is not smooth. If the model selection is not enough, the absolute value of the second deviation is large, namely the room load is large, so that the pipe temperature deviation, namely the temperature of the coil pipe of the indoor unit in the refrigeration mode is higher, or the temperature of the coil pipe of the indoor unit in the heating mode is lower. If the tube temperature is preferred and the current is larger, the resistance of the air duct is increased, so that unsmooth circulation is caused.
The method comprises the steps of increasing the rotating speed of the inner fan at the moment, increasing the air quantity of the inner fan, and utilizing more air to bring out the heat or the cold of the coil pipe of the inner fan, so that the indoor environment temperature is close to the indoor set temperature, and the method further comprises the step of obtaining the actual current value of the inner fan, and controlling the inner fan to stop increasing the rotating speed if the actual current value reaches the current upper limit value of the inner fan or if the first deviation absolute value is less than or equal to the first preset temperature difference or the second deviation absolute value is less than or equal to the second preset temperature difference.
As long as satisfy one of above-mentioned condition, explain or the refrigeration or the heating of air conditioner, make indoor ambient temperature approach user's settlement temperature, need not to increase the amount of wind of interior machine fan, or interior machine fan has reached maximum current, can't continue to increase the rotational speed and raise the power, so control interior machine fan and stop increasing the rotational speed, can reduce energy consumption, guarantee that interior machine fan is unlikely to overload, can the safe operation.
In a preferred technical scheme, the increase speed of the rotation speed of the indoor unit fan is that the increase value of each communication period is greater than 0rpm and less than or equal to 30rpm, and the communication period is a time interval for transmitting data to the controller by a sensor of the indoor unit of the air conditioner.
In a preferred technical scheme, the increase speed of the rotating speed of the inner fan is increased by 10rpm per communication period.
The rotating speed increasing range is adopted, the rotating speed increased every time is not too large, so that new sensor data can be obtained in the next communication period, the rotating speed increasing process can be immediately stopped after the requirement is met, and the risk of overburdened burning of an internal machine fan caused by too fast rotating speed increase is reduced.
In a preferred technical scheme, the preset operation time ranges from 20min to 120min, and/or the first preset temperature difference ranges from 8 ℃ to 20 ℃, and/or the second preset temperature difference ranges from 15 ℃ to 45 ℃.
In a preferred technical scheme, the preset operation time is 60min, and/or the first preset temperature difference is 10 ℃, and/or the second preset temperature difference is 25 ℃.
When the preset operation time is selected as the above time, it is described that the indoor unit of the air conditioner has insufficient cooling or heating speed of the air output to the indoor air for a long time. The first preset temperature difference is set to be the value above, which shows that the difference between the indoor environment temperature and the indoor set temperature is obvious, and the user experience is influenced. And the second preset temperature difference selects the values to explain the pipe temperature preference, and the problem is that whether the air conveyed by the fan of the indoor unit can fully take away the cold or heat of the coil pipe of the indoor unit or not so as to change the indoor environment temperature. Therefore, under the condition of the above parameter values, the rotating speed of the internal machine fan can be changed to improve the cooling or heating effect.
The second purpose of the invention is to provide a fan control device for an air conditioner internal unit, which is used for solving the technical problem that the fan control device is difficult to adapt to different lengths of air pipes.

Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Air conditioner entity equipment includes air conditioner internal unit fan, and the export connection hose wind channel of air conditioner internal unit fan can form great resistance when the wind channel distance is longer, and reduces the air-out static pressure of reality, influences user experience. In addition, the indoor unit of the air conditioner also comprises an indoor unit coil, namely a heat exchange pipe of the indoor heat exchanger, and a first temperature sensor can be arranged on the indoor unit coil to measure the temperature Tem of the indoor unit coil. In addition, a second temperature sensor can be arranged at the air inlet of the indoor unit of the air conditioner or in the air inlet duct to obtain the indoor environment temperature Tai.
Fig. 1 is a schematic flow chart of a method for controlling a fan of an air conditioner internal unit according to an embodiment of the present invention; as shown in fig. 1, the method for controlling the blower fan in the air conditioner may be applied to the air conditioner, and the method includes:
s210, obtaining indoor environment temperature Tai, indoor unit coil pipe temperature Tem, indoor set temperature Tset and continuous operation time;
in this case, it is necessary to obtain the continuous operation time because, in the time period when the air conditioner just starts to operate, the difference between the indoor ambient temperature Tai and the indoor set temperature Tset and the indoor unit coil temperature Tem is significant, and if this difference is used as a criterion for judgment, it will cause malfunction and unnecessarily increase the load of the indoor unit fan. Generally speaking, the time for the indoor environment temperature Tai to reach the temperature expected by the user is generally about ten minutes to one or two hours, and after the time, the corresponding temperature value is detected, so that the operation condition of the indoor unit fan can be judged.
S220, if a first deviation absolute value of the indoor environment temperature Tai and the indoor set temperature Tset is larger than a first preset temperature difference B, a second deviation absolute value of the indoor environment temperature Tai and the indoor unit coil pipe temperature Tem is larger than a second preset temperature difference C, and the continuous operation time is larger than a preset operation time A, controlling the indoor unit fan to increase the rotating speed.
If the capacity of the indoor unit of the air conditioner is insufficient, the preset temperature is not reached within the normal time, which is reflected in that the room temperature change is small, namely, the difference between the indoor environment temperature Tai and the indoor set temperature Tset is larger. Specifically, if in the cooling mode, the indoor ambient temperature Tai is significantly higher than the indoor set temperature Tset and is maintained for a certain time, the indoor ambient temperature is significantly not reached, or in the heating mode, the indoor ambient temperature Tai is significantly lower than the indoor set temperature Tset and is maintained for a certain time, the indoor ambient temperature is significantly not reached. And the difference between the indoor environment temperature Tai and the indoor unit coil pipe temperature Tem is also large, which shows that the pipe temperature preference, the condition that the indoor set temperature Tset cannot be achieved in the refrigeration mode is not caused by the higher indoor unit coil pipe temperature Tem, and the condition that the indoor set temperature Tset cannot be achieved in the heating mode is not caused by the lower indoor unit coil pipe temperature Tem, so that the problem is solved on an indoor unit fan, the air volume can be increased, the air supply capacity can be improved, and the cold quantity or the heat quantity of the indoor unit coil pipe can be conveyed to the indoor space so as to change the indoor environment temperature Tai.
Therefore, for each indoor unit, the rotating speed of the indoor unit fan suitable for the indoor unit can be found in a self-adaptive mode, the condition that the static pressure loss amount of each indoor unit is different due to different air channel lengths is avoided, different rotating speeds are matched for corresponding static pressure losses independently, the complexity of manual adjustment is reduced, and the adaptability of the multi-connected air conditioner to the static pressure air quantity is improved.
Specifically, the preset operation time A ranges from 20min to 120min, and/or the first preset temperature difference B ranges from 8 ℃ to 20 ℃, and/or the second preset temperature difference C ranges from 15 ℃ to 45 ℃.
Preferably, the preset running time A is 60min, and/or the first preset temperature difference B is 10 ℃, and/or the second preset temperature difference C is 25 ℃.
When the preset operation time a is selected as the above time, it is described that the indoor unit of the air conditioner has insufficient cooling or heating speed of the air output to the indoor air for a long time. The first preset temperature difference B is set to the above value, which indicates that the difference between the indoor ambient temperature Tai and the indoor set temperature Tset is significant, and the user experience is affected. And the second preset temperature difference C selects the value to indicate the pipe temperature preference, and the problem is that whether the air conveyed by the fan of the indoor unit can fully take away the cold or heat of the coil pipe of the indoor unit or not so as to change the indoor environment temperature Tai. Therefore, under the condition of the above parameter values, the rotating speed of the internal machine fan can be changed to improve the cooling or heating effect.
Specifically, the increase speed of the rotation speed of the indoor unit fan is that the increase value of each communication period is greater than 0rpm and less than or equal to 30rpm, and the communication period is a time interval for transmitting data to the controller by a sensor of the indoor unit of the air conditioner.
Preferably, the increase rate of the rotation speed of the inner fan is 10rpm per communication cycle.
The communication period may be, for example, 10 seconds to 2 minutes, and more specifically, may be 40 seconds or 1 minute.
The rotating speed increasing range is adopted, the rotating speed increased every time is not too large, so that new sensor data can be obtained in the next communication period, the rotating speed increasing process can be immediately stopped after the requirement is met, and the risk of the overlarge burning of the internal fan due to the fact that the rotating speed is increased too fast is reduced.
S220, obtaining an actual current value I of the internal machine fan and an actual rotating speed of the internal machine fan, if the actual current value I is larger than a preset current value Iset, increasing the rotating speed of the internal machine fan, and the preset current value Iset is a current value of a set static pressure output by the internal machine fan at the actual rotating speed.
And (4) eliminating accidental factors, such as the condition that the fan current is larger than the preset current value Iset due to the failure of an inner fan motor of the air conditioner, and not considering. If the current of the inner fan is larger than the current value of the set static pressure output when the current is at the actual rotating speed, the load of the inner fan is larger than the load under the set static pressure. When the load becomes large, the wind resistance becomes large.
Under the normal condition of model selection, after the unit operates stably, the indoor ambient temperature Tai approaches the indoor set temperature Tset. If the deviation between the indoor ambient temperature Tai and the indoor set temperature Tset is large, it indicates that either the model selection is insufficient or the air circulation of the indoor unit fan is not smooth. If the model selection is not enough, the absolute value of the second deviation is large, namely the room load is large, so that the pipe temperature deviation, namely the coil temperature Tem of the indoor unit in the cooling mode is higher, or the coil temperature Tem of the indoor unit in the heating mode is lower. If the tube temperature is preferred and the current is larger, the resistance of the air duct is increased, so that unsmooth circulation is caused.
Through increasing the rotational speed of interior machine fan this moment, can improve the amount of wind of interior machine fan, utilize more air to bring out the heat or the cold volume of indoor machine coil pipe to make indoor ambient temperature Tai be close indoor settlement temperature Tset.
And S230, if the actual current value I reaches the current upper limit value Imax of the inner fan, or if the first deviation absolute value is less than or equal to the first preset temperature difference B or the second deviation absolute value is less than or equal to the second preset temperature difference C, controlling the inner fan to stop increasing the rotating speed.
As long as satisfy one of above-mentioned condition, explain or the refrigeration or the heating of air conditioner, make indoor ambient temperature Tai approach user's settlement temperature, need not to increase the amount of wind of interior machine fan, or interior machine fan has reached maximum current, can't continue to increase the rotational speed and raise power, so control interior machine fan stops increasing the rotational speed, can reduce energy consumption, guarantee that interior machine fan is unlikely to overload, can the safe operation.
Fig. 2 is a schematic flowchart of another method for controlling fans in an air conditioner according to an embodiment of the present invention, where a multi-connected air conditioner is in a cooling mode, a factory default static pressure of an internal fan of the multi-connected air conditioner is 50Pa, an indoor set temperature Tset is 16 ℃, a current when a static pressure of 50Pa is generated when a rotation speed of the internal fan is 1000rpm is 0.8A, and a maximum current of the internal fan is 2.2A.
The method comprises the following steps:
s301, the indoor ambient temperature Tai is acquired, and then S302 is executed.
S302, acquiring the temperature Tem of the coil pipe of the indoor unit, and then executing S303.
S303, the indoor set temperature Tset is acquired, and then S304 is executed.
S304, acquiring the continuous operation time, and then executing S305.
S305, acquiring a first insulation deviation value of the indoor environment temperature Tai and the indoor set temperature Tset, and judging whether the first insulation deviation value is larger than a first preset temperature difference B-10 ℃, if so, executing S306, and if not, executing S305.
S306, acquiring a second absolute deviation value between the indoor environment temperature Tai and the indoor unit coil pipe temperature Tem, judging whether the second absolute deviation value is larger than a second preset temperature difference C-18 ℃, if so, executing S307, and if not, executing S305;
s307, judging whether the continuous operation time is greater than the preset operation time A60min, if so, executing S308, and if not, executing S305;
s308, acquiring an actual current value I of the inner fan and an actual rotating speed of the inner fan, and executing S309;
s309, judging whether the actual current value I is larger than the preset current value Iset, if so, executing S310, otherwise, executing S308;
s310, increasing the rotating speed of the inner fan to increase the rotating speed of the inner fan at the speed of 5rpm per communication period, and executing S311;
s311, obtaining an actual current value I of the internal machine fan, and executing S312;
s312, judging whether the actual current value I is larger than or equal to the current upper limit value Imax of the internal fan, if so, executing S316, and if not, executing S313;
s313, acquiring an indoor environment temperature Tai, an indoor unit coil pipe temperature Tem and an indoor set temperature Tset, and executing S314;
s314, judging whether the first absolute deviation value is less than or equal to a first preset temperature difference B-10 ℃, if so, executing S316, and if not, executing S315;
s315, judging whether the second absolute deviation value is smaller than or equal to a second preset difference value-18 ℃, if so, executing S316, otherwise, executing S310;
and S316, controlling the internal fan to stop increasing the rotating speed, and executing S301.
Taking the above-listed practical cases as an example, the indoor ambient temperature Tai is detected to be 30 ℃, the indoor unit coil temperature Tem is detected to be 8 ℃, and the current of the indoor unit fan is detected to be 1.3A, more than 0.8A and less than 2.2A. The first absolute deviation value is |30-16| =14 ℃ and > 10 ℃, and the second absolute deviation value is |30-8| =22 ℃ and > 18 ℃. Therefore, the rotating speed of the inner fan is controlled to increase by 5rpm for each communication period. In this embodiment, the time duration of the communication cycle is 1min.
When the current of the inner fan is detected to be close to 2.2A, the rotating speed of the fan is increased to 1100rpm from 1000rpm, the indoor environment temperature is changed to 26 ℃, the first absolute deviation value is |26-16| =10 ℃, the second absolute deviation value is |26-8| =18 ℃, and the corresponding preset temperature difference is equal, so that the rotating speed of the inner fan is stopped to be increased.

If the capacity of the indoor unit of the air conditioner is insufficient, the preset temperature is not reached within the normal time, which is reflected in that the room temperature change is small, namely, the difference between the indoor environment temperature Tai and the indoor set temperature Tset is larger. Specifically, if in the cooling mode, the indoor ambient temperature Tai is significantly higher than the indoor set temperature Tset and is maintained for a certain time, the indoor ambient temperature is significantly lower than the cooling temperature, or in the heating mode, the indoor ambient temperature Tai is significantly lower than the indoor set temperature Tset and is maintained for a certain time, the indoor ambient temperature is significantly lower than the heating temperature.
