Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As one implementation manner, the hardware environment architecture involved in the multi-connected air conditioner control method may be as shown in fig. 1.
Specifically, the multi-connected air conditioner includes: a processor 101, e.g. a CPU, a memory 102, a communication bus 103. Wherein a communication bus 103 is used for enabling the connection communication between these components. The processor 102 is used for calling an application program to perform functions such as cooling and heating.
The memory 102 may be a high-speed RAM memory or a non-volatile memory (e.g., a disk memory).
It is understood that, in an embodiment, a control program for implementing control of a multi-connected air conditioner is stored in the memory 102 of the multi-connected air conditioner, and when the processor 101 calls the control program from the memory 102, the following operations are performed:
comparing the first environment temperature values of the action areas of the indoor units;
determining a target indoor unit corresponding to an action area with the highest first environment temperature value and other indoor units except the target indoor unit;
and adjusting the target indoor unit and the other indoor units in a linkage manner to reduce the ambient temperature value of the action area of the target indoor unit.
Alternatively, in another embodiment, a control program for implementing the control process of the multi-connected air conditioner is stored in a computer-readable storage medium, and the processor 101 of the air conditioner may call the control program from the computer-readable storage medium during the control process of the air conditioner, which is described above.
Based on the hardware architecture of the air conditioner, various embodiments of the control method of the multi-connected air conditioner are provided.
In a first embodiment, referring to fig. 2, a method for controlling a multi-connected air conditioner according to the present embodiment includes the following steps:
step S10, comparing the first environment temperature values of the action areas of the indoor units;
step S20, determining a target indoor unit corresponding to the action area with the highest first environment temperature value and other indoor units except the target indoor unit;
and step S30, adjusting the target indoor unit and the other indoor units in a linkage manner to reduce the environmental temperature value of the action area of the target indoor unit.
The multi-connected air conditioner comprises an outdoor unit and a plurality of indoor units, wherein the outdoor unit is connected with the indoor units. The multi-connected air conditioner in the embodiment is applied to rooms with large space, such as offices, restaurants and the like. Because the room space is large, the room is divided into a plurality of areas, each area is correspondingly provided with one indoor unit, and the indoor units act on the room at the same time, so that the environmental temperature in the room can achieve a better adjusting effect as soon as possible.
However, when a plurality of indoor units simultaneously operate, temperature imbalance may occur in a plurality of areas due to installation errors of the indoor units, heat loads of various areas of a room, and the like. Based on this, in the embodiment, the multi-connected air conditioner is set to obtain the first ambient temperature value of the action area of each indoor unit in real time or at regular time in the operation process, and then compare the first ambient temperature values of the action areas of the indoor units to obtain the action area with the highest first ambient temperature value, and further determine the target indoor unit corresponding to the action area with the highest first ambient temperature value, determine other indoor units except the target indoor unit based on the target indoor unit, and then adjust the target indoor unit and the other indoor units in a linkage manner to reduce the ambient temperature value of the action area of the target indoor unit. Through the continuous circulation of the mode, the temperature value of the action area with the highest first environment temperature value can be gradually reduced to the temperature which is the same as or similar to that of other areas, so that the aim of temperature balance of each action area is fulfilled, and the adjusting effect of the multi-connected air conditioner is improved.
The first environmental temperature value can be obtained by detecting the return air temperature of each indoor unit, and if a temperature sensor is arranged at the return air inlet of each indoor unit, the first environmental temperature value is detected. Or, in order to improve the accuracy of the first ambient temperature value, the first ambient temperature value may also be detected based on at least one temperature sensor disposed in the indoor unit operation area. Or a plurality of temperature sensors are arranged from near to far away from the indoor unit, and the first environment temperature value is determined through average temperature values of the plurality of temperature sensors so as to improve the accuracy of judgment of the first environment temperature value.
Referring to fig. 3, the multi-connected air conditioner of the present embodiment includes an outdoor unit 100 and a plurality of indoor units 200, wherein after the indoor unit 200 corresponding to the action region with the highest first ambient temperature value is obtained, other indoor units than the target indoor unit are obtained based on the target indoor unit, and the other indoor units except the target indoor unit include an indoor unit adjacent to the target indoor unit and/or an indoor unit not adjacent to the target indoor unit. In this embodiment, the indoor unit adjacent to the target indoor unit is a first indoor unit, and the indoor unit not adjacent to the target indoor unit is a second indoor unit, as shown in fig. 3, if it is determined that the target indoor unit is an H indoor unit, the other indoor units except the target indoor unit include: the indoor unit comprises an indoor unit A, an indoor unit B, an indoor unit C, an indoor unit D, an indoor unit E, an indoor unit F, an indoor unit G and an indoor unit J. The first indoor units adjacent to the H indoor units are an E indoor unit, a G indoor unit and a J indoor unit, and the second indoor units not adjacent to the H indoor units are an A indoor unit, a B indoor unit, a C indoor unit, a D indoor unit and an F indoor unit.
Based on this, in this embodiment, the manners for adjusting the target indoor unit and the other indoor units in a linkage manner to reduce the ambient temperature value of the active area of the target indoor unit include, but are not limited to, the following two manners:
in an embodiment, referring to fig. 4, the other indoor units include a first indoor unit adjacent to the target indoor unit, that is, a linkage adjustment target indoor unit and a first indoor unit adjacent to the target indoor unit, and specifically, the step of linkage adjusting the target indoor unit and the other indoor units includes:
step S31, reducing the set temperature value of the target indoor unit by a first threshold value;
step S32, increasing the rotation speed of the first indoor unit by a second threshold value; and/or adjusting an air deflector of the first indoor unit to increase the air volume blown out to the action area of the target indoor unit by the first indoor unit.
When a target indoor unit corresponding to an action area with the highest first environment temperature value is determined based on the first environment temperature value of the action area of each indoor unit, the capacity output of the target indoor unit is judged to be smaller relative to other indoor units, or the heat load of the action area of the target indoor unit is judged to be large, and at the moment, the capacity output of the target indoor unit needs to be increased, or the temperature of the action area of the target indoor unit needs to be reduced. At the moment, the temperature of the action area of the target indoor unit is reduced in a mode of increasing the air quantity blown out to the action area of the target indoor unit by combining the reduction of the set temperature value of the target indoor unit by a first threshold value and the adjustment of an air deflector of a first indoor unit adjacent to the target indoor unit, so that the temperature of the action area of the target indoor unit is balanced with the environmental temperature values of the action areas of other indoor units, and the uneven distribution of the room environmental temperature values is avoided.
Specifically, referring to fig. 3, if the H indoor unit is the target indoor unit, the set temperature value of the target indoor unit is decreased by the first threshold, and the air deflector of at least one of the E indoor unit, the G indoor unit, and the J indoor unit is adjusted so that the amount of air blown to the H indoor unit is increased. Therefore, the target indoor unit and other indoor units are adjusted in a linkage mode, so that the temperature value of the action area of the target indoor unit can be quickly reduced, and indoor balance can be quickly achieved.
The first threshold value is different based on the model of the multi-connected air conditioner, and the value range of the first threshold value is 1-5 ℃. That is, if the current set temperature value of the target indoor unit is 24 ℃, the set temperature of the target indoor unit may be reduced to 19 ℃ to 23 ℃ after the first threshold is reduced corresponding to the set temperature of the target indoor unit. In some embodiments, the set temperature value of the target indoor unit may be reduced to a minimum safe set value.
And increasing the rotating speed of the first indoor unit by a second threshold value so as to increase the air output of the first indoor unit. The second threshold value is different based on the model of the multi-connected air conditioner, and the value range of the second threshold value is 1 rotation to the highest rotation speed or (1 gear to the highest gear).
It can be understood that, in this embodiment, the amount of air blown out by the first indoor unit to the action region of the target indoor unit can be increased by increasing the rotation speed of the first indoor unit by the second threshold, and the amount of air blown out by the first indoor unit to the action region of the target indoor unit can also be increased by adjusting the air deflector of the first indoor unit. In a preferred embodiment, the amount of air blown out by the first indoor unit into the target indoor unit action region is increased by combining a mode of increasing the rotation speed of the first indoor unit by a second threshold value and a mode of adjusting the air deflector of the first indoor unit.
In addition, there are various ways to increase the amount of air blown out by the first indoor unit to the target indoor unit action region, for example, the angle of the air deflector of the first indoor unit is adjusted so that the air outlet of the first indoor unit faces the target indoor unit action region.
Or, in some types of multi-connected air conditioners, the amount of air blown out by the first indoor unit to the action area of the target indoor fan is increased by gathering the dispersed air output in one direction and increasing the air output in the direction. In these types of multi-split air conditioners, the step of adjusting the air deflector of the first indoor unit to increase the amount of air blown out by the first indoor unit toward the active area of the target indoor unit includes:
acquiring an air outlet of the first indoor unit and a target air outlet adjacent to the target indoor unit;
and closing the air deflectors of other air outlets except the target air outlet.
Specifically, the indoor unit in this embodiment includes a plurality of air outlets, each air outlet discharges air in a different direction, and based on the position arrangement of the plurality of indoor units, an air outlet is adjacent to a certain indoor unit, and based on the opening of the air outlet facing the adjacent indoor unit, the air outlet supplies air to the active area of the adjacent indoor unit. Therefore, the air volume blown out to the action area of the target indoor unit by the first indoor unit can be increased by increasing the air volume of the air outlet.
Therefore, in this embodiment, after the target indoor unit is determined, the target air outlet adjacent to the target indoor unit among all the air outlets of the first indoor unit is determined based on the position of the target indoor unit and the position of the first indoor unit adjacent to the target indoor unit, and the air output of the target air outlet is increased to increase the air output of the first indoor unit to the action area of the target indoor unit. The method for increasing the air volume of the target air outlet includes, but is not limited to, closing air deflectors of other air outlets except the target air outlet.
In this embodiment, the manner of closing the air deflectors of the air outlets other than the target air outlet is based on that the air volume generated by the first indoor unit under the action of the fan is gathered at the target air outlet, so that the air volume is prevented from being scattered at a plurality of air outlets and blown out, and therefore the air volume of the target air outlet is increased, and the air volume blown out to the action area of the target indoor unit by the first indoor unit is increased.
In some embodiments, the angles of the air deflectors of the target air outlet are adjusted while the air deflectors of other air outlets except the target air outlet are closed, so as to increase the air outlet distance of the target air outlet, so that more air is blown to the action area of the target indoor unit, the cooling speed of the action area of the target indoor unit is increased, and the temperature in a room is quickly balanced.
In another embodiment of the linkage adjustment of the target indoor unit and the other indoor units, referring to fig. 5, the other indoor units include a second indoor unit that is not adjacent to the target indoor unit, that is, a linkage adjustment target indoor unit and a second indoor unit that is not adjacent to the target indoor unit, and specifically, the linkage adjustment of the target indoor unit and the other indoor units includes:
step S31, reducing the set temperature value of the target indoor unit by a first threshold value;
step S33, switching the current operation mode of the second indoor unit to an air supply mode;
and step S34, after the second indoor unit operates in the air supply mode for a preset time, the operation mode before the air supply mode is switched is recovered.
When a target indoor unit corresponding to an action area with the highest first environment temperature value is determined based on the first environment temperature value of the action area of each indoor unit, the capacity output of the target indoor unit is judged to be smaller relative to other indoor units, or the heat load of the action area of the target indoor unit is judged to be large, and at the moment, the capacity output of the target indoor unit needs to be increased, or the temperature of the action area of the target indoor unit needs to be reduced. At the moment, the aim of quickly reducing the temperature of the action area of the target indoor unit is achieved by combining the mode of reducing the set temperature value of the target indoor unit by a first threshold value and adjusting the operation mode of a second indoor unit which is not adjacent to the target indoor unit, and the condition that the room environment temperature value is not uniformly distributed is avoided.
Specifically, referring to fig. 3, if the H indoor unit is the target indoor unit, the set temperature value of the target indoor unit is decreased by the first threshold, so that the capacity output of the target indoor unit is increased, the cooling output of the target indoor unit is increased, and the purpose of rapidly decreasing the temperature of the target indoor unit action area is achieved. And the operation mode of at least one indoor unit of the indoor unit A, the indoor unit B, the indoor unit C, the indoor unit D and the indoor unit F is adjusted in a combined manner to reduce the cold output of the indoor unit A, the indoor unit B, the indoor unit C, the indoor unit D and the indoor unit F, so that the cold output of the target indoor unit is increased, and the ambient temperature value of the action area of the target indoor unit is further accelerated. Therefore, the target indoor unit and other indoor units are adjusted in a linkage mode, so that the temperature value of the action area of the target indoor unit can be quickly reduced, and indoor balance can be quickly achieved.
The first threshold value is different based on the model of the multi-connected air conditioner, and the value range of the first threshold value is 1-5 ℃. That is, if the current set temperature value of the target indoor unit is 24 ℃, the set temperature of the target indoor unit may be reduced to 19 ℃ to 23 ℃ after the first threshold is reduced corresponding to the set temperature of the target indoor unit. In some embodiments, the set temperature value of the target indoor unit may be reduced to a minimum safe set value.
In this embodiment, the manner of adjusting the second indoor unit not adjacent to the target indoor unit includes, but is not limited to, the following manners:
if the current operation mode of the second indoor unit is switched to the air supply mode. If the current operation mode of the second indoor unit is the refrigeration mode, the refrigeration mode of the current operation of the second indoor unit is switched to the air supply mode, so that most of the cold output by the outdoor unit is conveyed to the target indoor unit, the output cold of the target indoor unit is increased, and the temperature of the action area of the target indoor unit is rapidly reduced.
It should be noted that after the operation mode of the second indoor unit is switched to the air supply mode, the ambient temperature value of the action area of the second indoor unit is affected, which causes the ambient temperature value of the action area of the second indoor unit to increase, so that in order to prevent the ambient temperature value of the action area of the other indoor unit from being affected when the ambient temperature value of the target indoor unit is adjusted, the operation mode before the air supply mode is switched is resumed after the second indoor unit is operated in the air supply mode for a preset time period. Wherein the value range of the preset time is 1-100 min.
That is, in this embodiment, the operation mode of the second indoor unit is switched to the air supply mode, the output cold amount of the target indoor unit is increased, after a period of time, the original operation mode is switched (if the original operation mode is the refrigeration mode, the refrigeration mode is switched), and the ambient temperature value in the action area of the second indoor unit is maintained in an intermittent switching manner.
Further, referring to fig. 6, fig. 6 is a second embodiment of the control method of the multi-split air conditioner based on the first embodiment. Specifically, in this embodiment, based on the above embodiment, the target indoor unit and the other indoor units are adjusted in a linkage manner such that the set temperature value of the target indoor unit is reduced by a first threshold value; increasing the rotating speed of the first indoor unit by a second threshold value; and/or, when the manner of adjusting the air deflector of the first indoor unit is adjusted, in order to further improve the effect of adjusting the ambient temperature value of the target indoor unit, so that the ambient temperature values at various positions in the room reach a rapid balance, the present embodiment further includes, after the step of increasing the rotation speed of the first indoor unit by a second threshold, and/or adjusting the air deflector of the first indoor unit to increase the air volume blown out by the first indoor unit to the action area of the target indoor unit:
step S35, switching the current operation mode of the second indoor unit to an air supply mode;
and step S36, after the second indoor unit operates in the air supply mode for a preset time, the operation mode before the air supply mode is switched is recovered.
In this embodiment, the other indoor units include a first indoor unit adjacent to the target indoor unit and a second indoor unit not adjacent to the target indoor unit. That is, the target indoor unit, the first indoor unit, and the second indoor unit are adjusted in a linkage manner in this embodiment. The specific adjustment mode is as follows:
and if the current operation mode of the second indoor unit is a refrigeration mode, the refrigeration mode of the current operation of the second indoor unit is switched to an air supply mode, so that most of the cold output by the outdoor unit is transmitted to the target indoor unit, the output cold output of the target indoor unit is increased, and the reduction speed of the temperature of the action area of the target indoor unit is faster by combining with the reduction of the set temperature value of the target indoor unit, so that the temperature in the room is faster and balanced.
It should be noted that after the operation mode of the second indoor unit is switched to the air supply mode, the ambient temperature value of the action area of the second indoor unit is affected, which causes the ambient temperature value of the action area of the second indoor unit to increase, so that in order to prevent the ambient temperature value of the action area of the other indoor unit from being affected when the ambient temperature value of the target indoor unit is adjusted, the operation mode before the air supply mode is switched is resumed after the second indoor unit is operated in the air supply mode for a preset time period. Wherein the value range of the preset duration is 1-100 min.
That is, in this embodiment, the operation mode of the second indoor unit is switched to the air supply mode, the output cold amount of the target indoor unit is increased, after a period of time, the original operation mode is switched (if the original operation mode is the refrigeration mode, the refrigeration mode is switched), and the ambient temperature value in the action area of the second indoor unit is maintained in an intermittent switching manner.
Based on the above, in this embodiment, the target indoor unit, the first indoor unit adjacent to the target indoor unit, and the second indoor unit not adjacent to the target indoor unit are linked, and the positions of the first indoor unit and the second indoor unit are different, and the target indoor unit, the first indoor unit, and the second indoor unit are adjusted in different manners, such as the target indoor unit directly adjusting the set temperature value and directly adjusting the ambient temperature value of the target indoor unit action region, while the first indoor unit is adjacent to the target indoor unit and can achieve the purpose of reducing the ambient temperature value of the target indoor unit action region by adjusting the amount of air blown out to the target indoor unit action region, and the second indoor unit is not adjacent to the target indoor unit and increases the amount of cold output to the target indoor unit by switching the operation mode to the air supply mode, the purpose of reducing the environmental temperature value of the target indoor unit action area is achieved. Therefore, the purpose of adjusting the environmental temperature value of the target indoor unit action area is achieved, and meanwhile, the influence of linkage adjustment of other indoor units on the environmental temperature values of other indoor unit action areas is reduced as much as possible. If the first indoor unit is adjacent to the target indoor unit, the aim of linkage adjustment is achieved by adjusting the air volume blown out of the action area of the target indoor unit, and meanwhile, the influence of environment temperature rise caused by switching the operation mode to the air supply mode is avoided. If the second indoor unit is not adjacent to the target indoor unit, the air volume blown out from the action area of the target indoor unit cannot be increased by adjusting the air deflector, so that the cooling capacity output to the target indoor unit is increased by switching the air supply mode. That is, the position characteristics of the indoor fans in this embodiment are matched with a suitable linkage mode to adjust the environmental temperature values of the areas in the room, so that the room temperature balance adjustment is realized, and the influence on the adjustment of the environmental comfort level of other indoor machines on the action areas of the indoor machines in the linkage adjustment process is avoided.
It is understood that, in some embodiments, steps S35 and S36 are repeatedly performed at a preset cycle, and after performing N cycles, the process returns to perform step S10, or the following embodiments are continuously performed.
Further, referring to fig. 7, fig. 7 is a third embodiment of the control method of the multi-connected air conditioner based on the second embodiment. In this embodiment, in order to further improve the adjustment effect of room temperature balance, after the step of resuming the operation mode before the air supply mode is switched after the second indoor unit operates in the air supply mode for the preset time period, the method further includes:
step S37, acquiring a second environment temperature value of the target indoor unit action area;
step S38, comparing the difference value between the first environmental temperature value and the second environmental temperature value of the target indoor unit action area;
step S39, determining whether the difference is smaller than a first difference;
and when the difference is smaller than the first difference, returning to the step of 35, and switching the current operation mode of the second indoor unit to the air supply mode.
If not, that is, when the difference is greater than or equal to the first difference, step S40 is executed to increase the set temperature value of the target indoor unit by a second threshold, where the second threshold is smaller than the first threshold.
In this embodiment, after the linkage adjustment of the target indoor unit, the first indoor unit, and the second indoor unit in the second embodiment, a second ambient temperature value (ambient temperature value after linkage adjustment) of the action area of the target indoor unit is obtained, and then a difference between the first ambient temperature value and the second ambient temperature value is compared to determine whether the ambient temperature value of the action area of the target indoor unit is reduced after the linkage adjustment of the second embodiment. If the difference is smaller than a first difference, it is determined that the influence of the linkage adjustment of the second embodiment on the ambient temperature of the target indoor unit action area is not large, or the target indoor unit cannot achieve the purpose of adjustment even after the set temperature is reduced, at this time, the ambient temperature of the target indoor unit action area is continuously adjusted by returning to repeatedly executing the mode of switching the current operation mode of the second indoor unit to the air supply mode until the difference is greater than or equal to the first difference, it is determined that the temperature adjustment on the target indoor unit action area is effective, at this time, in order to avoid that the set temperature value of the target indoor unit is reduced to influence the energy distribution of the indoor unit to each indoor unit, thereby influencing the ambient influence of other indoor units on the action area, when it is determined that the temperature adjustment on the target indoor unit action area is effective, the set temperature of the target indoor unit is restored to the set temperature value before the target indoor unit is reduced by gradually increasing the set temperature value of the target indoor unit, so that the phenomenon that the distribution of cold energy in other indoor units is influenced after the set temperature value of a certain indoor unit is adjusted, and further the temperature of each area of a room is unbalanced is effectively prevented.
Specifically, when the difference is greater than or equal to the first difference, the set temperature value of the target indoor unit is increased by a second threshold value, where the second threshold value is smaller than the first threshold value, and if the first threshold value is 1-5 ℃, the second threshold value is 0.5 ℃. Wherein the first difference is greater than or equal to 1 ℃.
Further, after the step of increasing the set temperature value of the target indoor unit by a second threshold value, where the second threshold value is smaller than the first threshold value, the method further includes:
comparing the set temperature value after the second threshold value is increased with the set temperature value before the first threshold value is reduced;
and when the set temperature value after the second threshold value is increased is the same as the set temperature value before the first threshold value is reduced, returning to the step of comparing the first environment temperature values of the areas where the indoor units are located.
And when the set temperature value after the second threshold value is increased is smaller than the set temperature value before the first threshold value is reduced, returning to the step of increasing the set temperature value of the target indoor unit by the second threshold value.
In this embodiment, after the difference is greater than or equal to the first difference, the set temperature value of the target indoor unit is increased by a second threshold, the set temperature value after the second preset value is increased is compared with the set temperature value before the first threshold is decreased, if the set temperature value after the second threshold is increased is smaller than the set temperature value before the first threshold is decreased, it is determined that the set temperature value after the second threshold is increased does not return to the set temperature value before the first threshold is decreased, at this time, the step of increasing the set temperature value of the target indoor unit by the second threshold is executed again, and the set temperature value of the target indoor unit is continuously increased until the set temperature value of the target indoor unit returns to the set temperature value before the first threshold is decreased. If the set temperature value after the second threshold value is increased is the same as the set temperature value before the first threshold value is reduced, the set temperature value after the second threshold value is increased is judged to be restored to the set temperature value before the first threshold value is reduced, at this moment, the step of comparing the first environmental temperature values of the areas where the indoor units are located is continuously executed, the action area with the highest first environmental temperature value is continuously detected, a new target indoor unit is re-determined, and then the adjusting process in each embodiment is executed.
In the process of recovering the set temperature value of the target indoor unit, the influence on the ambient temperature value of the action area of the target indoor unit is reduced by gradually increasing the set temperature value, and the ambient temperature value of the action area of the target indoor unit is prevented from being rapidly increased along with the recovery of the set temperature value, so that the linkage regulation effect of the multi-connected air conditioner is influenced.
In some embodiments, when the set temperature value after increasing the second threshold is smaller than the set temperature value before decreasing the first threshold, after a preset time interval, the step of increasing the set temperature value of the target indoor unit by the second threshold is returned to. Wherein the preset time interval ranges from 1min to 100 min. In the process of recovering the set temperature value of the target indoor unit, the influence on the environmental temperature value of the target indoor unit action area can be reduced to a lower program in a mode of gradually rising within a fixed time interval, and then the adjusting effect on the environmental temperature value of the target indoor unit action area in each embodiment is maintained.
