Referring to fig. 2, a flowchart of a first embodiment of an energy-saving control method for a multi-split air conditioning system according to the present invention includes the following steps:
One or more multi-split air conditioning systems are typically provided within the same building or site to achieve a predetermined cooling or heating effect. Each multi-split air conditioning system generally includes one or more indoor units. And acquiring the operation information of the indoor unit in the starting operation state in the current multi-split system. The operation information includes a set temperature of the indoor unit, an operation mode, and the like. The number of the indoor units in the starting operation state is one or more. Generally, the set temperature of the indoor unit air conditioner is the temperature set by the user on the air conditioner remote controller. In this embodiment, the set temperature may be a default set temperature of the indoor unit, or may be a set temperature customized by a user, which is not limited herein.
And step 203, calculating the difference degree of the indoor unit according to the operation information.
When the indoor unit is started to operate, the outdoor unit of the multi-split system where the indoor unit air conditioner is located also starts to operate, and the compressor enters a working state. And the normal refrigerating and heating requirements of the whole multi-split system can be ensured only by maintaining the outdoor unit compressor to operate at a certain frequency when the outdoor unit operates. Because the particularity of the multi-split air-conditioning system is that a plurality of indoor units of one refrigerant system share one or more outdoor units, when the outdoor units operate, the consumed electric quantity is commonly borne by the indoor units which are started to operate in the multi-split air-conditioning system. And the electric quantity born by each indoor unit which is started to operate is directly related to the capacity demand state of the indoor unit. For example, the indoor unit in the whole multi-split system is set to refrigerate at 26 ℃ and the electric quantity allocated to the indoor unit is much less than that of the indoor unit set to refrigerate at 17 ℃. Therefore, in order to avoid energy waste and reduce electricity cost, the high-energy-consumption indoor unit needs to be regulated according to the operation conditions of other indoor units of the whole multi-split system.
In this embodiment, the difference degree of each indoor unit is calculated according to the operation information of each indoor unit in the operation state acquired in the above step. In this embodiment, the difference degree is a difference degree between the energy consumption of any one indoor unit in an operating state and the energy consumption of the other indoor units in the operating state. The degree of difference may be calculated based on the set temperature of the indoor unit, or other methods may be employed. Similarly, other measurement parameters (energy efficiency parameters) may be used for the degree of difference, and are not particularly limited herein.
In this embodiment, when analyzing and checking the indoor units in the multi-split system, if it is detected that the energy consumption of any currently operating indoor unit is greatly different from that of other indoor units in an operating state, the indoor unit is controlled, and otherwise, the indoor unit is controlled to continue to operate according to the current operating state.
And step 207, controlling the indoor unit in the starting operation state to keep the current working state.
In this embodiment, when it is detected that the energy consumption of any currently operating indoor unit is not much different from the energy consumption of other indoor units in the operating state, that is, the difference degree is within the preset range, the indoor unit in the power-on operating state can be controlled to keep the current operating state unchanged, so that the predetermined energy saving effect can be achieved.
And 209, regulating and controlling the first indoor unit corresponding to the difference degree larger than the preset threshold value.
In this embodiment, when it is detected that the energy consumption of any currently operating indoor unit is greatly different from that of other indoor units in an operating state, that is, the difference degree exceeds the preset threshold, the energy-saving control is performed on the first indoor unit of which the difference degree exceeds the preset threshold.
According to the energy-saving control method of the multi-split air conditioning system, the difference degree of the indoor units is calculated according to the acquired operation information of the indoor units in the starting operation state; and when the difference degree is greater than the preset threshold value, regulating and controlling the first indoor unit corresponding to the difference degree greater than the preset threshold value according to the priority attribute of the indoor unit, otherwise, controlling the indoor unit in the starting operation state to keep the current working state. The energy-saving control method of the multi-split air conditioning system can effectively save energy to operate on the premise of meeting the comfort level of a user, has a good energy-saving effect and high intelligent degree, and meets the requirements of the user.
Furthermore, due to the particularity of the multi-split air-conditioning system, a plurality of indoor units are arranged in the same refrigerant system, and each indoor unit air conditioner has an independent user and is independently controlled. According to different user requirements, different priority levels are set for the indoor units used by the indoor units. The first indoor unit is regulated and controlled according to the preset priority of the indoor unit, and user experience is improved.
Further, in the second embodiment, as shown in fig. 3, the step 209 includes a process of adjusting and controlling the first indoor unit corresponding to the difference degree greater than the preset threshold according to the priority attribute of the indoor unit, where the process includes:
The first indoor unit is an indoor unit with the difference degree larger than a preset threshold value, and priority attributes corresponding to the indoor units are obtained. In the present embodiment, the priority is set to at least four levels including the highest level, the second lowest level, and the lowest level.
And step 302, when the priority of the first indoor unit is the highest level, controlling the first indoor unit to keep the current running state.
When the priority of the first indoor unit is the highest level, even if the first indoor unit has high energy consumption (large difference degree or low set temperature), the first indoor unit is controlled to keep the current running state unchanged based on the requirement of the priority, so that the use experience of a user can be improved.
And step 303, controlling to adjust the set temperature of the first indoor unit to a preset temperature range when the priority of the first indoor unit is the second highest.
And when the priority of the first indoor unit is the next highest, controlling to adjust the set temperature of the first indoor unit to a preset temperature range. In this embodiment, the predetermined temperature range may be determined according to the set temperatures of other indoor units in the power-on operation state. For example, the preset temperature range may be between the minimum value and the maximum value of the set temperatures of other indoor units in the power-on operation state.
And step 304, when the priority of the first indoor unit is the next lower level, controlling to adjust the working mode of the first indoor unit to a preset mode.
When the difference degree of the first indoor unit is large (high energy consumption) and the priority is the next lower level, the working mode of the first indoor unit is adjusted to be the preset mode. The predetermined mode may be an air blowing mode or a sleep mode, and is not limited herein.
And 305, controlling to close the first indoor unit when the priority of the first indoor unit is the lowest level.
When the difference degree of the first indoor unit is large (high energy consumption) and the priority is the lowest level, the first indoor unit is directly controlled to be closed, so that the energy consumption can be reduced to the maximum extent, and the energy-saving effect is achieved.
It should be noted that, the steps 302 to 305 may be executed in parallel, and the execution order is not limited at all here.
Further, in the third embodiment, as shown in fig. 4, step 203 includes:
In this embodiment, the set temperatures and the priority attributes of all the indoor units in the power-on operation state are searched and obtained from the memory 1005. The set temperature of the indoor unit in the on operation state and the priority attribute thereof may be stored in the memory 1005 in a form of recording.
And step 404, calculating the difference degree of the indoor unit according to the set temperature and the priority attribute.
And calculating the difference degree between any one indoor unit in the starting operation state and other indoor units in the starting operation state according to the set temperature and the priority attribute of the indoor unit in the starting operation state.
Further, in the fourth embodiment, step 404 includes:
(1) and eliminating the set temperature of the indoor unit with the highest priority.
Since the set temperature of the indoor unit with the highest priority is too low, the difference of other indoor units is affected, in this embodiment, the set temperature of the indoor unit with the highest priority is rejected for a more humanized angle of indoor unit regulation.
(2) Calculating the mean value of the residual set temperature, calculating the difference value between the residual set temperature and the mean value, and taking the absolute value of the difference value as the difference degree; or
The degree of difference of the remaining set temperatures is calculated using a linear regression method.
In this embodiment, the difference between each set temperature and the average value may be calculated by calculating the average value of the rejected set temperatures, and the absolute value of the difference may be used as the difference of the indoor unit.
Alternatively, the degree of difference in the set temperatures may be calculated using a linear regression method, such as the least squares method, for the remainder.
The difference is calculated by the method, the calculation amount is small, so that the regulation and the control are timely and convenient, and the comfort level of a user is improved while electricity is saved.
Further, in a fifth embodiment, the manner of acquiring the priority attribute of the indoor unit in the method includes:
