Technical Field

The application relates to the technical field of intelligent household appliances, in particular to a method and a device for controlling a multi-split air conditioner, the multi-split air conditioner and a storage medium.

Background

The super-ratio of the multi-split air conditioner is the ratio of the sum of all indoor unit loads to the outdoor unit load. In order to save cost, the over-proportioning ratio is generally recommended to be 120-150% when the model is selected for installation. In this case, it is generally not recommended that the user turn-on load exceeds 100%, and if the indoor units turned on by the user at the same time exceed a limited ratio, the outdoor unit is not turned on. Thus, the user is provided with poor use effect experience, and complaints even can occur.

The related art discloses a control method of a multi-split air conditioner, which comprises the following steps: receiving an instruction of starting a target standby indoor unit; judging whether the target standby indoor unit meets a starting condition or not, wherein the starting condition comprises Q _{Inner part} /Q _{Outer cover} ≤K，Q _{Inner part} Is the sum of the load of the target standby indoor unit and the load of all the operating indoor units, Q _{Outer cover} The load of the outdoor unit, and K is a quota coefficient; if the target standby indoor unit meets the starting-up condition, controlling the target standby indoor unit to start up; and if the target standby indoor unit does not meet the starting-up condition, controlling the target standby indoor unit to enter a waiting queue until the target standby indoor unit is started up under the condition of meeting the starting-up condition.

In the process of implementing the embodiments of the present disclosure, it is found that at least the following problems exist in the related art:

although the technology can realize that the super-proportion of the multi-split air conditioner is not limited when the multi-split air conditioner is assembled, the problem that the load capacity of an outdoor unit is exceeded due to too many indoor units which operate simultaneously can be avoided. However, in the related art, when the standby indoor unit is turned on under overload, the standby indoor unit needs to run according to the standby sequence, and cannot be controlled according to the requirement. Therefore, in the related art, when the multi-split air conditioner is over-matched and a standby indoor unit exists, the flexibility of controlling the operation of the standby indoor unit is poor.

It is to be noted that the information disclosed in the above background section is only for enhancement of understanding of the background of the present application and therefore may include information that does not constitute prior art known to a person of ordinary skill in the art.

The multi-split air conditioner usually selects an over-distribution configuration, namely the sum of all indoor unit loads of the multi-split air conditioner is greater than the rated load of an outdoor unit.

The embodiment of the disclosure provides a multi-split air conditioner, which comprises a plurality of indoor units, an outdoor unit and a processor. The processor can control the operation of a plurality of indoor units. Under the condition of overload starting, the processor can control the running or standby of the indoor unit which is newly started to run and the indoor unit which is running, and can control the running sequence of the indoor unit to be treated. In the operation process of the multi-split air conditioner, part of the indoor units are in an operation state, and the rest of the indoor units are in a standby state or a shutdown state.

In combination with the multi-split air conditioner, the embodiment of the disclosure provides a method for controlling the multi-split air conditioner. As shown in fig. 1, the method includes:

s101, the processor receives a starting operation instruction of the first target indoor unit.

The first target indoor unit is an indoor unit which is required to be operated when the user is started. For example, the a-subscriber turns on the indoor unit of the room using the remote controller and sets the heating operation to 26 ℃. At this time, the processor may receive a power-on heating operation instruction of the first target indoor unit.

And S102, under the condition that the total operation load of the indoor units is less than or equal to the operation load of the outdoor unit, the processor operates the first target indoor unit according to the instruction.

When part of indoor units of the multi-split air conditioner are in the running state, the rest indoor units are in the standby state or the shutdown state. In the case where the standby indoor unit exists in the indoor unit, the total operation load of the indoor unit is the sum of the load of the operating indoor unit, the load of the standby indoor unit, and the load of the first target indoor unit. In the case where the indoor unit does not have a standby indoor unit, the total operation load of the indoor unit is the sum of the load of the operating indoor unit and the load of the first target indoor unit. The operation load of the outdoor unit is the rated load of the outdoor unit. The total operation load of the indoor units is less than or equal to the operation load of the outdoor unit, so that the first target indoor unit can be operated according to the instruction under the condition that the first target indoor unit is not overloaded after being operated.

S103, under the condition that the total running load of the indoor units is greater than that of the outdoor unit, the processor judges whether the priority of the first target indoor unit is greater than or equal to a priority threshold value, if so, the processor runs the first target indoor unit according to an instruction and adjusts one or more indoor units in the second target indoor units to be standby; wherein the second target indoor unit is a low priority indoor unit in operation.

The total operation load of the indoor units is larger than that of the outdoor unit, which shows that the first target indoor unit can be operated in an overload mode, so that the first target indoor unit cannot be operated directly according to instructions under the overload condition. The priority of the indoor unit is set in advance. For example, the priority of the indoor unit is set by using indoor unit codes, and the lower the indoor unit code, the higher the priority. Different indoor units are provided with different indoor unit codes. The priority threshold may be set according to the needs of the user. For example, the priority threshold may be set to the priority of the indoor unit with an indoor unit code of 4. Then the priority of the indoor units coded as 1, 2, 3 is greater than the priority threshold. The low-priority indoor unit is an indoor unit with the priority smaller than the priority threshold. Or the low-priority indoor unit is an indoor unit with the priority lower than that of the first target indoor unit.

In the embodiment of the disclosure, the first target indoor unit may operate according to the priority of the indoor unit when the indoor unit is turned on in an overload state. Meanwhile, some low-priority indoor units in operation need to be in standby mode to avoid overload operation. The priority represents the priority requirements of the user. In the related art, under the condition that the indoor units are started in an overload mode, the first target indoor unit needs to wait in a standby mode and operates according to the standby sequence. Compared with the prior art, the method can improve the flexibility of the operation control of the indoor unit under the conditions of the overload start of the multi-split air conditioner and the overload start of the indoor unit.

Optionally, before the processor adjusts one or more indoor units of the second target indoor unit to be in standby, the method further includes: and the processor accumulates the running loads of one or more indoor units in the second target indoor unit according to the sequence of the priorities of the indoor units in the second target indoor unit from low to high until the accumulated running load is greater than or equal to the running load of the first target indoor unit. The processor determines one or more indoor units in the second target indoor units as the indoor units needing to be in standby. For example, the second target indoor unit has 4 indoor units, with indoor unit codes 7, 8, 9, 10, respectively. The smaller the intra coding, the higher the priority. Then, the operation loads of the indoor units encoded as 10 are sequentially accumulated from the indoor unit. And comparing the running load of the first target indoor unit every time of accumulation, and stopping accumulation under the condition that the accumulated running load is greater than or equal to the running load of the first target indoor unit. For example, the operation load of the first target indoor unit is 3500W, the operation load of the indoor unit with the indoor unit code of 10 is 2500W, and the operation load of the indoor unit with the indoor unit code of 9 is 2500W. Then the running load sum of the indoor unit with indoor unit code 10 and the indoor unit with indoor unit code 9 is already greater than the running load of the first target indoor unit. Therefore, the indoor unit having the indoor unit number of 10 and the indoor unit having the indoor unit number of 9 are determined as the indoor units that need to be on standby. In this way, the indoor unit with the highest priority is preferentially operated, and the indoor unit with the lowest priority is on standby. Under the condition of avoiding overload operation of the multi-split air conditioner, the indoor unit with high priority requirement of a user can be ensured to operate preferentially. Therefore, the flexibility of the operation control of the indoor unit is improved and the user experience is improved under the conditions of the overload start of the multi-split air conditioner and the overload start of the indoor unit.

With reference to fig. 2, another method for controlling a multi-split air conditioner according to an embodiment of the present disclosure includes:

s201, the processor receives a starting operation instruction of the first target indoor unit.

And S202, under the condition that the total running load of the indoor units is greater than the running load of the outdoor unit, the processor judges whether the priority of the first target indoor unit is greater than or equal to a priority threshold value, if so, the processor accumulates the running loads of one or more indoor units in the second target indoor units according to the sequence from low to high of the priorities of the indoor units in the second target indoor units until the accumulated running load is greater than or equal to the running load of the first target indoor unit.

S203, the processor determines one or more indoor units in the second target indoor units as the indoor units that need to be in standby.

And S204, the processor operates the first target indoor unit according to the instruction and adjusts one or more indoor units in the second target indoor units to be in standby.

And the second target indoor unit is a running low-priority indoor unit.

In the embodiment of the disclosure, under the condition that the indoor unit is turned on in an overload state, the first target indoor unit can operate according to the priority of the indoor unit. Meanwhile, a part of the indoor units with low priority in operation need to be in standby state to avoid overload operation. The priority represents the priority requirements of the user. And preferentially operating the indoor unit with high priority, and waiting the indoor unit with the lowest priority. Under the condition of avoiding overload operation of the multi-split air conditioner, the indoor unit with high priority requirement of a user can be ensured to operate preferentially. Therefore, the flexibility of the operation control of the indoor unit is improved and the user experience is improved under the conditions of the overload start of the multi-split air conditioner and the overload start of the indoor unit.

Optionally, in a case that the priority of the first target indoor unit is less than the priority threshold, the method further includes: the processor determines that the first target indoor unit operates or is in standby according to the indoor environment temperature, the target temperature and the operation load of the first target indoor unit. The indoor environment temperature is the real-time environment temperature of the room where the indoor unit is located, and the target temperature is the set temperature of the indoor unit. Therefore, under the condition that the priority of the first target indoor unit is low, whether the first target indoor unit is operated or not can be determined according to the indoor environment temperature, the target temperature and the operation load of the first target indoor unit, and the comfort degree of a user is ensured to a high degree. Therefore, the flexibility of the operation control of the indoor unit is improved and the user experience is improved under the conditions of the overload start of the multi-split air conditioner and the overload start of the indoor unit.

With reference to fig. 3, another method for controlling a multi-split air conditioner according to an embodiment of the present disclosure includes:

s301, the processor receives a starting operation instruction of the first target indoor unit.

S302, the processor judges whether the total operation load of the indoor unit is less than or equal to the operation load of the outdoor unit. If so, step S303 is performed. Otherwise, step S304 is executed.

And S303, the processor operates the first target indoor unit according to the instruction.

S304, the processor judges whether the priority of the first target indoor unit is larger than or equal to a priority threshold value. If so, step S305 is performed. Otherwise, step S306 is executed.

S305, the processor operates the first target indoor unit according to the instruction and adjusts one or more indoor units in the second target indoor units to be in standby; wherein the second target indoor unit is a low priority indoor unit in operation.

And S306, the processor determines the first target indoor unit to run or stand by according to the indoor environment temperature, the target temperature and the running load of the first target indoor unit.

In the embodiment of the disclosure, the first target indoor unit may operate according to the priority of the indoor unit when the indoor unit is turned on in an overload state. Meanwhile, a part of the indoor units with low priority in operation need to be in standby state to avoid overload operation. The priority represents the priority requirements of the user. And preferentially operating the indoor unit with high priority, and waiting the indoor unit with the lowest priority. Under the condition of avoiding overload operation of the multi-split air conditioner, the indoor unit with high priority requirement of a user can be ensured to operate preferentially. And under the condition that the priority of the first target indoor unit is low, whether the first target indoor unit is operated or not can be determined according to the indoor environment temperature, the target temperature and the operation load of the first target indoor unit, and the comfort level of a user is ensured to a higher degree. Therefore, the flexibility of the operation control of the indoor unit is improved and the user experience is improved under the conditions of the overload start of the multi-split air conditioner and the overload start of the indoor unit.

Optionally, the determining, by the processor, that the first target indoor unit is in operation or in standby according to the indoor ambient temperature, the target temperature, and the operation load of the first target indoor unit includes: processor calculates Δ T _m ＝∣T _ao-m -T _set-m | a. If Δ T _m Satisfies the first condition, and Q _m And if the second condition is met, the processor operates the first target indoor unit according to the instruction and adjusts part of indoor units in the second target indoor units to be in standby.

When the temperature difference between the indoor environment temperature and the target temperature exceeds a certain value, it indicates that the difference between the indoor environment temperature of the user at the moment and the suitable temperature of the human body is large. Therefore, whether the first target indoor unit is operated or not is determined according to the first condition, and the user requirements can be met. Therefore, the flexibility of the operation control of the indoor unit is improved and the user experience is improved under the conditions of the overload start of the multi-split air conditioner and the overload start of the indoor unit.

Has a minimum p value of 2. Therefore, the first 2 indoor units among the third target indoor units are determined as the indoor units that need to be on standby. In this way, by identifying the indoor unit that is in standby from among the indoor units whose temperature difference between the indoor ambient temperature and the target temperature is less than or equal to a certain value, the user does not experience discomfort by having the indoor unit with a smaller temperature difference in standby. Meanwhile, the first target indoor unit with a large temperature difference can be preferentially operated. Therefore, the flexibility of the operation control of the indoor unit is improved and the user experience is improved under the conditions of the overload start of the multi-split air conditioner and the overload start of the indoor unit.

Alternatively, T ₆ At 3 deg.C, 3.5 deg.C or 4 deg.C. When the indoor environment temperature approaches to the target temperature, the air speed of the indoor unit is reduced to redistribute the refrigerant, so that the indoor unit is ensured to be smallThe load is required to operate. The target temperature can not be reached quickly, the standby is carried out, and then the reciprocating starting is carried out after the indoor environment temperature is reduced. Therefore, the problem that the frequency of the compressor and the reliability of the whole machine are influenced due to too large change of the load requirement of the whole machine can be avoided.

In this way, when the indoor unit is turned on in an overload state, the operation of the standby indoor unit can be performed from high to low in the order of the operation priority of the standby indoor unit when the operation condition of the standby indoor unit is satisfied. The operating priority represents a user's preferred operating requirements. In the related art, under the condition that the indoor unit is started in an overload mode, the indoor unit needs to run according to the standby sequence after standby waiting. Compared with the prior art, the method can operate according to the user requirement under the condition that the multi-split air conditioner is in super-distribution and the standby indoor unit exists, and improves the flexibility of operation control of the standby indoor unit.
