Fig. 1 is a schematic flow chart of a method for intelligent energy-saving control of an air conditioning device according to an embodiment of the present invention.
Detailed Description
The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The embodiment of the application provides an intelligent energy-saving control method for air conditioning equipment, which is used for controlling the air conditioning equipment. The air conditioning equipment comprises a plurality of air conditioning units and a plurality of sensors, one sensor corresponds to one air conditioning unit one by one, the plurality of air conditioning units are arranged in a machine room along an array, and the machine room is used for radiating multi-unit equipment such as a server.
The embodiment of the application provides a method for intelligent energy-saving control of air conditioning equipment, referring to fig. 1, comprising the steps of S101-S103:
S101, acquiring a first temperature map, wherein the first temperature map is a graph group formed by arranging temperature data acquired by a plurality of sensors along the corresponding sensor positions, acquiring an initial average temperature T v1 based on the first temperature map, and acquiring a plurality of first temperature change values delta T 1 between the temperature T 1 acquired by each sensor and the initial average temperature T v1.
The first temperature map is a graph obtained by arranging data acquired by a plurality of sensors arranged in an array in an area, for example, 3*3 sensors are arranged in a machine room, and the first temperature map is as follows:
The temperature can be displayed more intuitively by the array representation, and in this embodiment, the initial average temperature T v1 =52.2 is taken as an example of the machine room. In this example, the numerical values are expressed in degrees celsius (°c), but in other embodiments, the numerical values may be expressed in other units or numerical symbols, which are not limited thereto.
Based on the first temperature map, a plurality of first temperature change values Δt 1 between the temperature T 1 acquired by each of the sensors and the initial average temperature T v1 can be obtained.
Specifically, the first temperature change values Δt 1＝Tv1-t1, that is, the plurality of first temperature change values Δt 1 are distributed as follows in the corresponding positions in the first temperature map:
It can be appreciated that the first temperature change value Δt 1 is a difference between the temperature obtained by each sensor and the average temperature, so that a temperature change value Δt 1 measures the difference between the temperature at the location and the average temperature to some extent.
S102, acquiring a second temperature map after a preset time interval, wherein the first temperature map corresponds to the second temperature map, acquiring a conditional average temperature T v2 based on the second temperature map, and acquiring a plurality of second temperature change values delta T 2 between the temperature T 2 acquired by each sensor and the initial average temperature T v2 at the moment.
The second temperature map is formed by changing the first temperature map after a certain time interval, and when the temperature in the machine room changes, the temperature is necessarily reflected on the second temperature map. Illustratively, when the partial region temperature changes, the second temperature map is as follows:
Based on this, T v2 =51.5;
As in step S103, Δt 2＝Tv2-t2, the distribution of the plurality of second temperature change values Δt 2 is as follows:
S103: based on the correspondence between the first temperature map and the second temperature map, a fluctuation value Δt 0 between the first temperature change value Δt 1 and the second temperature change value Δt 2 of each pair of correspondence is determined, a temperature change position is determined based on the fluctuation value, and a regulation scheme is determined based on the temperature change position.
It will be appreciated that, since the first temperature change value Δt 1 represents the difference between the temperature at the location and the average temperature, and the second temperature change value Δt 2 represents the change of the difference between the temperature at the location and the average temperature at the location, the same location difference value is not easy to change or has small change when the overall temperature is increased or decreased, such as by the influence of the external environment. In contrast, when the overall temperature change is affected by a certain point in the plurality of points, the change in the difference value at the same point should be large. For example, in the present embodiment, the difference between the first temperature variation value Δt 1 and the second temperature variation value Δt 2 is a fluctuation value Δt 0, which satisfies: Δt 0＝Δt1-Δt2. The distribution of the plurality of fluctuation values based on the corresponding positions is as follows:
It is evident from this that after a certain time the main points of temperature change are the points at 0 =4.7 and at 0 = -9.3. The temperature of the position can be accurately regulated and controlled by the mode, global regulation and control are not needed, and the purposes of energy conservation and emission reduction are achieved.
Specifically, in order to obtain the main point of change, the change value Δt of the average temperature, that is, Δt=t v2-Tv1, in this embodiment, Δt=0.7 may be obtained first.
In order to facilitate the calculation of the machine, in this embodiment, a judgment value may be introduced to assist the calculation, and in this embodiment, if any one or more of the judgment values Z is greater than the rest of the judgment values Z, it is determined that the positions of the corresponding sensors in the first temperature map and the second temperature map corresponding to the obtained judgment values Z are the target adjustment positions, that is, the judgment values z= |Δt| - Δt 0 |and, similarly, the judgment values also indicate that the point changes after the overall change is avoided.
In the present embodiment, the distribution of the plurality of judgment values is as follows:
it is obvious that in this embodiment, the points where the temperature changes are z=4 and z=10. In this way, the position of the modulation may be determined, and then the modulation scheme may be determined based on the target modulation position.
In the process of determining the regulation scheme, an integral regulation mode is needed when the integral temperature change is large, but the integral regulation inevitably leads to the increase of energy consumption. Thus, in some embodiments, an average change Δt between the initial average temperature T v1 and the conditional average temperature T v2 may also be obtained to measure whether overall regulation is required.
Specifically, Δt=t v2-Tv1, that is, Δt=0.7 in the present embodiment;
And if the average change value delta T is smaller than or equal to the preset threshold value, determining that the regulation and control scheme is the non-integral cooling scheme, so that the functions of energy conservation and emission reduction are realized.
Optionally, the operating power of all the air conditioning units is increased during the overall control process, i.e. during the entire control process. In order to obtain a more accurate regulation result, a third temperature map, that is, a temperature map after a period of time of the second temperature map may be obtained, and the target average temperature T v3 may be obtained based on the third temperature map. And if the target average temperature T v3 is the same as the initial average temperature T v1, proving that the regulation is in place, and stopping increasing the running power of the air conditioning unit at the moment.
In the non-integral regulation process, firstly, an air conditioning unit needing regulation, namely a target air conditioning unit, needs to be determined. And determining a target air conditioning unit based on the target adjusting position, wherein the target air conditioning unit is the air conditioning unit corresponding to the target adjusting position in a plurality of air conditioning units.
It can be understood that if the fluctuation value Δt 0 corresponding to the target adjustment position is greater than or equal to 0, it can be determined that the temperature at the position has increased, and specific data of adjustment and control needs to be determined by the judgment value Z. Specifically, a regulation parameter e may be introduced to control, where the regulation parameter e is used to regulate the target air conditioning unit, and the regulation parameter e is equal to the judgment value Z.
Optionally, determining a target output temperature T m of the target air conditioning unit according to the regulation and control parameter e;
and controlling the output temperature of the target air conditioning unit according to the target output temperature T m.
Specifically, since the output temperature of the air conditioner is always higher than the temperature of the final regulation result in the regulation process, the regulation is performed at a lower temperature than the target in the regulation process, and the difference is a redundancy value. Specifically, the current output temperature T 0 of the target air conditioning unit is first obtained, and then the redundancy value f is determined based on the current output temperature T 0. It can be appreciated that the redundancy value is subject to change upon receipt of the current ambient temperature and the regulated temperature. In this embodiment, the redundancy value f satisfies:
f＝(T0-T)2K；
wherein T is the current ambient temperature, and K is a constant;
Finally, determining the target output temperature T m based on the current output temperature, the redundancy value f and the regulation parameter e, wherein the target output temperature T m satisfies: t m＝T0 + f + e.
In contrast, if the fluctuation value Δt 0 corresponding to the target adjustment position is smaller than zero, the target air conditioning unit is not adjusted.
