In the following description, for purposes of explanation and not limitation, specific details are set forth such as particular system structures, techniques, etc. in order to provide a thorough understanding of the embodiments of the invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.
In order to make the objects, technical solutions and advantages of the present invention more apparent, the following description is made by way of specific embodiments with reference to the accompanying drawings.
Fig. 1 is a flowchart illustrating an implementation of an energy saving control method for an air conditioner according to an embodiment of the present invention. As shown in fig. 1, in step 101, obtaining an ambient temperature corresponding to a current operating cycle, wherein a preset operating time period is divided into a plurality of operating cycles according to a change of a real-time ambient temperature, and a change of the real-time ambient temperature in the same operating cycle does not exceed a preset threshold;
in the embodiment of the invention, the operation time of the preset operation time interval can be divided into a plurality of operation cycles according to the real-time change of the environmental temperature, and the same operation cycle is a period of time with little real-time change of the environmental temperature. Thus, for each operating cycle, an operating parameter is determined which matches the ambient temperature of the current operating cycle. For example, the preset operating period may be one day.
In the embodiment of the present invention, the ambient temperature corresponding to the current operation period may be a historical average temperature in the current operation period, or may be an actually measured temperature.
In step 102, determining an operating parameter corresponding to the current operating cycle as a first set value based on the ambient temperature of the current operating cycle and a preset operating parameter-ambient temperature corresponding relationship, wherein the preset operating parameter-ambient temperature corresponding relationship is a corresponding relationship under the condition of lowest energy consumption determined according to historical operating data of the air conditioner;
in the embodiment of the present invention, the current ambient temperature may be detected, and the operating parameter corresponding to the current ambient temperature may be obtained according to the preset operating parameter-ambient temperature correspondence, and is used as the first setting value.
In an alternative embodiment, the operating parameter-ambient temperature correspondence may be obtained according to the following: acquiring historical operation data of the air conditioner, wherein the historical operation data comprises operation parameters, operation energy consumption and environment temperature of the air conditioner; and obtaining the corresponding relation between the operating parameters and the ambient temperature under the lowest operating energy consumption based on the historical operating data.
In this embodiment, the operation data of the refrigeration host and the refrigeration water pump of the data center can be automatically collected, the operation data is divided according to the ambient temperature, the characteristic data in each mode is extracted to form a mode strategy, that is, the corresponding relation between the operation parameter and the ambient temperature under the condition of minimum operation energy consumption is found according to the historical operation data, so as to determine the first set value.
In step 103, the air conditioner is controlled to operate based on the first set value in the current operation period.
In the embodiment of the present invention, in the current operation period, the air conditioner may be controlled to operate based on the first set value, and in the next operation period, the air conditioner may be controlled to operate according to the first set value corresponding to the next operation period.
In the embodiment of the present invention, the air conditioner operation parameter may be a set temperature of a refrigeration host of the air conditioner, and when the air conditioner operation parameter is applied to a data center scene, the set temperature may be a value in a required temperature range of the data center, for example, if the required temperature range of the data center is 20 to 25 degrees celsius, the set temperature may be 23 degrees celsius.
In practical application, the set temperatures of the refrigeration hosts of the air conditioners are different, and the energy consumption is correspondingly different, in addition, the external environment temperature is greatly different in different seasons, even different time periods of the preset operation time period, the difference of the environment temperatures is also an important factor influencing the energy consumption of the air conditioners, and the set temperatures corresponding to the lowest energy consumption are different under different environment temperatures. Thus, the first set point may also be one that changes as the ambient temperature changes.
In addition, the operation parameter of the air conditioner may also be an operation frequency of a refrigeration water pump of the air conditioner, and in the same way as above, when the operation parameter of the air conditioner is the operation frequency of the refrigeration water pump of the air conditioner, the first setting value may be a fixed value selected from a required operation frequency range, or may be a setting value which is associated with the ambient temperature and changes with the change of the ambient temperature.
In one embodiment, when the operation parameter of the air conditioner selected for the energy saving control is the operation frequency of the cooling water pump of the air conditioner, the set temperature of the cooling main unit of the air conditioner is fixed. When the operation parameter of the air conditioner selected by the energy-saving control is the set temperature of the refrigeration host of the air conditioner, the operation frequency of the refrigeration water pump of the air conditioner is fixed.
In one embodiment, the operation frequency of the refrigeration water pump of the air conditioner can be selected as the operation parameter for energy-saving control in one period, and the set temperature of the refrigeration host of the air conditioner can be selected as the operation parameter for energy-saving control in another period, and the operation frequency and the set temperature are alternately performed.
In one implementation, the step 103 may include:
1031, obtaining a second setting value larger than the first setting value and a third setting value smaller than the first setting value based on the first setting value and a preset parameter adjustment rule;
in the embodiment of the present invention, according to the first setting value determined in step 102, a second setting value larger than the first setting value and a third setting value smaller than the first setting value may be obtained according to a certain parameter adjustment rule.
In practical applications, the target setting value corresponding to the lowest air conditioner energy consumption may be the first setting value, may be a value slightly larger than the first setting value, or may be a value slightly smaller than the first setting value.
In an alternative embodiment, the parameter adjustment rule comprises adjusting a step value;
correspondingly, one implementation manner of obtaining a second setting value larger than the first setting value and a third setting value smaller than the first setting value based on the first setting value and a preset parameter adjustment rule in the above steps may include:
the sum of the first set value and the adjustment step value is set as a second set value, and the difference between the first set value and the adjustment step value is set as a third set value.
In an application scenario, the operation parameter of the air conditioner may be a set temperature of the refrigeration host, the first set value may be 23 degrees celsius, the adjustment step value may be 0.5 degrees celsius, the second set value is 23.5 degrees celsius, and the third set value is 22.5 degrees celsius.
Step 1032, controlling the air conditioner to operate based on the first set value in a first operation time of a current operation period, controlling the air conditioner to operate based on the second set value in a second operation time of the current operation period, and controlling the air conditioner to operate based on the third set value in a third operation time of the current operation period;
step 1033, comparing the operation energy consumptions of the air conditioners corresponding to the first operation time, the second operation time and the third operation time respectively, and taking a set value corresponding to the operation time with the minimum operation energy consumption as a fourth set value;
step 1034, controlling the air conditioner to operate based on the fourth set value in a fourth operation time period of the current operation period.
In the embodiment of the invention, in one operation period, the air conditioner can be respectively controlled to operate at three set values in three operation time lengths, then the power consumption of the air conditioner in the three operation time lengths is counted, and the set value corresponding to the operation time length with the lowest power consumption is used as the target set value for optimizing and adjusting. And controlling the air conditioner to operate at the target setting value for a fourth operation period within the operation period.
For example, the preset operation period may be divided into three operation periods, each of the operation periods is 8 hours, the first operation period, the second operation period, and the third operation period may be 1 hour, the fourth operation period may be 5 hours, the operation parameter of the air conditioner may be the set temperature of the refrigeration host, the first set value may be 23 degrees celsius, the adjustment step value may be 0.5 degrees celsius, the second set value may be 23.5 degrees celsius, and the third set value may be 22.5 degrees celsius; the control of the air conditioner operating parameters may be as follows: in a period with the duration of 8 hours, the set temperature of the first hour refrigeration main machine is 23 ℃, the set temperature of the second hour refrigeration main machine is 23.5 ℃, and the set temperature of the third hour refrigeration main machine is 22.5 ℃. Then, the operation energy consumption of each of the three hours is counted, if the operation energy consumption of the first hour is 1000W, the operation energy consumption of the second hour is 1100W, and the operation energy consumption of the third hour is 950W, it can be obtained that the set temperature of 22.5 degrees celsius corresponding to the third hour should be a better set value corresponding to lower energy consumption, and then the set temperature of the refrigeration host is set to 22.5 degrees celsius for the remaining 5 hours (the fourth operation time) in the cycle.
In an optional embodiment, the duration of the current operation period is a sum of the first operation duration, the second operation duration, the third operation duration and the fourth operation duration;
the energy-saving control method further comprises the following steps: and in the next period of the current operation period, taking the fourth set value in the current operation period as the first set value of the next period.
In the embodiment of the present invention, the better setting value corresponding to the lower energy consumption determined in the previous operation period may be used as the first setting value of the present operation period.
The embodiment of the invention provides an energy-saving control method of an air conditioner, which comprises the steps of obtaining the environment temperature corresponding to the current operation cycle, wherein the preset operation time interval is divided into a plurality of operation cycles according to the change of the real-time environment temperature, and the change of the real-time environment temperature in the same operation cycle does not exceed a preset threshold value; determining an operating parameter corresponding to the current operating cycle as a first set value based on the ambient temperature of the current operating cycle and a preset operating parameter-ambient temperature corresponding relationship, wherein the preset operating parameter-ambient temperature corresponding relationship is a corresponding relationship under the condition of lowest energy consumption determined according to historical operating data of the air conditioner; and controlling the air conditioner to operate based on the first set value in the current operation period.
