Referring to FIG. 2 , which is a schematic flowchart of the first embodiment of the method for energy-saving control of the multi-connected air-conditioning system of the present invention, the method includes the following steps:

Step 201, detecting the working status of any indoor unit in any multi-connected air-conditioning system.

In the same building or place, in order to achieve a predetermined cooling or heating effect, one or more multi-connected air conditioning systems are usually installed. Each multi-split air conditioning system usually includes one or more indoor units. The operating status of any indoor unit in any multi-connected air-conditioning system can be detected by detection devices such as sensors. In this embodiment, the working state of the indoor unit includes a running state and an off state.

Step 203, determine the energy consumption level of the multi-connected air conditioning system according to the working status of the indoor units.

The energy consumption level of each multi-connected air-conditioning system is determined according to the indoor units in the running state of each multi-connected air-conditioning system.

In this embodiment, the energy consumption level can be calculated according to the energy efficiency ratio of the air conditioner. For example, it can be divided into three levels: 1, 2, and 3. Level 1 means that the product has reached the international advanced level, and the most energy-saving, that is, energy consumption The lowest; grade 2 means relatively power-saving; grade 3 means that the energy efficiency of the product is the average level of the Chinese market. The energy efficiency grade can also be divided into 1-5 to represent different energy efficiency grades, which are not specifically limited here.

Step 205, judging whether the energy consumption level is within the predetermined energy consumption range, if yes, execute step 207, otherwise, execute step 209.

In this embodiment, the predetermined energy consumption interval may be preset as a standard interval, or may be set by the user. For example, when most of the indoor units in the current multi-connected air-conditioning system (the specific number is determined by the total number of indoor units in a multi-connected air-conditioning system, which can be preset or set by the user) are running, it can be determined that the current multi-connected The energy consumption level of the air conditioning system is within the predetermined energy consumption range.

Step 207, controlling the indoor units in the multi-connected air-conditioning system to maintain the current working state.

When the energy consumption level is within the predetermined energy consumption range, the indoor units in the multi-connected air-conditioning system can be controlled to keep the current working state unchanged, so as to achieve the predetermined energy-saving effect.

Step 209, the step of controlling the multi-connected air-conditioning system to perform energy-saving regulation.

When the energy consumption level is not within the predetermined energy consumption interval, the step of controlling the current multi-connected air-conditioning system to perform energy-saving adjustment and control.

In this embodiment, the manner of obtaining the predetermined energy consumption range includes: user-defined; or acquisition through machine learning according to pre-stored energy consumption data. In this way, the intelligent degree of the user's use of the air conditioner can be improved.

In this embodiment, for example, case 1: the current energy consumption level of the multi-connected air-conditioning system is in the predetermined energy consumption range, that is, when most indoor units of the multi-connected air-conditioning system are running, the power consumed by the outdoor units is determined by how many This situation is the most economical and energy-saving for each indoor unit air conditioner user;

Situation 2: When only one or two indoor unit air conditioners in the multi-connected air conditioner system are running, the entire multi-connected air conditioner system is in a state of small load operation. A middle school costs electricity.

Because when the outdoor unit is running, the compressor of the outdoor unit needs to be kept running at a certain frequency to ensure the normal cooling and heating requirements of the entire multi-split air conditioning system. The power is slightly less, but since the number of indoor units responsible for the power is much less than in case 1, for the indoor units in case 2, one or two indoor units in operation are required to bear the operating costs of the entire system.

Therefore, there is a need for a step of controlling the multi-connected air-conditioning system to perform energy-saving regulation.

The energy-saving control method of the multi-connected air-conditioning system in the above embodiment detects the working state of any indoor unit in the multi-connected air-conditioning system; determines the energy consumption level of the multi-connected air-conditioning system according to the working state of the indoor unit, and then Energy-saving control of the multi-connected air-conditioning system according to the consumption level. The energy-saving control method of the multi-connected air-conditioning system can effectively save energy and operate under the premise of satisfying user comfort, has good energy-saving effect, and has a high degree of intelligence, thereby meeting the needs of users.

Further, in the second embodiment, as shown in FIG. 3 , the process of performing energy-saving regulation on each multi-connected air-conditioning system that does not reach the predetermined energy consumption range in step 209 includes:

Step 301, acquire the first indoor unit in the running state in the first multi-connected air-conditioning system that needs to be regulated.

In this embodiment, the first multi-connected air-conditioning system that needs to be regulated is a multi-connected air-conditioning system whose energy consumption level does not reach a preset energy consumption range. The first indoor unit in the on-running state in the first multi-connected air-conditioning system is obtained, and the first indoor unit is marked. The number of the first indoor units is one or more, and the way of labeling may be numbers, for example, the numbers of the first indoor units may be N1, N2, N3, and so on.

Step 303, acquiring the second multi-connected air-conditioning system whose energy consumption level is within a predetermined energy consumption range, and obtaining the second indoor unit in the off state in the second multi-connected air-conditioning system.

In this embodiment, most of the indoor units in the second multi-connected air-conditioning system are in the running state, the second indoor units in the off state in the second multi-connected air-conditioning system are obtained, and the second indoor units are marked. The number of the second indoor units is one or more, and the way of labeling may be numbers, for example, the numbers of the second indoor units may be M1, M2, M3, and so on.

Step 305, according to the priority attribute of the first indoor unit, control to turn off the first indoor unit and correspondingly turn on the second indoor unit, wherein the priority attribute includes the first priority and the second priority, and the first priority is higher on the second priority.

According to the preset priority attribute of the first indoor unit, the first indoor unit is controlled to be turned off while the second indoor unit is correspondingly turned on, and the corresponding second indoor unit is turned on to replace the first indoor unit for cooling (heating), and at the same time It can ensure that the cooling (heating) effect is not affected. This automatic control method can effectively help the user to use the air conditioner more reasonably so as to achieve the purpose of saving energy, electricity and money.

It should be noted that the above step 301 and step 303 can be executed in parallel or sequentially. There is no limitation on the execution sequence of step 301 and step 303. In this embodiment, step 301 and step 303 can be executed in parallel.

In one embodiment, the energy-saving control method for a multi-connected air-conditioning system further includes pre-dividing priority attributes of all indoor units.

There are many ways to divide the priority attribute of the indoor unit. In this embodiment, the division method is: first priority (high priority, the operation mode of the indoor unit is fixed, and the automatic control function of the energy-saving control method is not accepted); And the second priority, which is the low priority, accepts the automatic control function of the energy-saving control method.

By setting the priority level of the indoor unit, the energy-saving control can be made more balanced and the comfort of the user can be improved.

Further, in the third embodiment, as shown in FIG. 4, step 305 includes:

Step 307, judging whether the priority of the first indoor unit is the first priority, if yes, execute step 309, otherwise execute step 311.

When the priority of the first indoor unit is the first priority, the first indoor unit is controlled to maintain the current running state.

In this embodiment, since the first priority is that the indoor unit does not accept the automatic control function state of the energy-saving control method, the first indoor unit is controlled to maintain the current running state. In this way, the energy-saving control can be made more balanced, and the user's comfort can be improved.

Step 309, controlling the first indoor unit to maintain the current running state.

Step 311, judge whether the priority of the first indoor unit is the second priority, if yes, execute step 313, otherwise, end the process.

When the priority of the first indoor unit is the second priority, the first indoor unit is controlled to be turned off, and the second indoor unit is correspondingly turned on.

In this embodiment, the indoor units with the second priority among the first indoor units are analyzed, these air conditioners are turned off, and the corresponding ones of the second indoor units are turned on to replace the cooling (heating) of the first indoor units. For example, the first indoor units numbered N1, N2, N3... are controlled to be turned off, and the second indoor units numbered M1, M2, M3... are turned on at the same time. The number of the first indoor units controlled to be turned off and the number of the second indoor units controlled to be turned on may be the same or different, and may be specifically determined according to the indoor ambient temperature and the energy efficiency ratio of the indoor units.

It should be noted that the determination order of step 307 and step 309 can be interchanged, and there is no limitation on the order of execution here.
