Description

Technical Field

[0001] This application relates to the field of air conditioning technology, and more specifically, to a method, apparatus, and electronic device for determining an air conditioning operation mode. Background Technology

[0002] With the continuous development of data centers, their huge energy consumption and environmental impact are becoming increasingly apparent. In addition to IT equipment, air conditioning systems are the largest energy-consuming unit in data centers. Therefore, optimizing air conditioning systems is an important measure for energy conservation and consumption reduction in data centers. Adopting energy-saving technologies and through reasonable debugging and active operation and maintenance management of air conditioning systems can make the energy-saving effect of the entire air conditioning system better.

[0003] Extensive research has been conducted on energy conservation in data center air conditioning systems, but no suitable energy consumption calculation method has been provided for refrigerant pump air conditioning systems. For example, controlling the switching of air conditioning operation based on indoor dry-bulb temperature does not achieve the effect of saving energy in the air conditioning system. Determining cooling capacity based on parameters such as supply air temperature and return air temperature, and focusing on energy efficiency ratio based on cooling capacity and power, does not comprehensively consider parameters such as energy efficiency ratio, cooling capacity, and supply air temperature to determine the air conditioning operation mode switching mechanism, thus making it impossible to accurately switch the air conditioning operation mode.

[0033] In the above operating environment, this application provides an embodiment of a method for determining an air conditioner operating mode. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Also, although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in a different order than that shown here.

[0034] Figure 2 This is a flowchart of a method for determining an air conditioner operating mode according to an embodiment of this application, such as... Figure 2 As shown, the method includes the following steps:

[0035] Step S202: Obtain the current outdoor temperature.

[0036] In step S202 above, the current outdoor temperature is the outdoor temperature within the target area.

[0037] Step S204: When the indoor temperature reaches the target steady-state temperature, determine the required cooling capacity of the air conditioner in each operating mode based on the current outdoor temperature and the cooling capacity model, wherein the cooling capacity model is used to represent the relationship between the outdoor temperature and the cooling capacity of the air conditioner.

[0038] In step S204 above, the ultimate goal of determining the air conditioner's operating mode is to achieve a target steady-state indoor temperature, such as maintaining a constant indoor temperature of 25°C. Therefore, the condition for obtaining the current outdoor temperature and determining the subsequent air conditioner operating mode is that the indoor temperature needs to reach the target steady-state temperature. Furthermore, the cooling capacity model in step S204 is a digital model, obtained through experimental data and statistical analysis. It describes the relationship between outdoor temperature and air conditioner cooling capacity. Under different air conditioner operating modes, the required cooling capacity is determined based on the current outdoor temperature. These operating modes include compressor operating mode, refrigerant pump operating mode, and compressor-refrigerant pump hybrid operating mode.

[0039] Step S206: Determine the operating mode corresponding to the lowest value of cooling capacity as the base mode of the air conditioner, and determine the total power consumption of the air conditioner in each operating mode based on the current outdoor temperature.

[0040] In step S206 above, based on the cooling capacity model, among the three operating modes of refrigerant pump operation mode, compressor operation mode, and refrigerant pump-compressor hybrid operation mode, the operating mode with the lowest cooling capacity is determined as the reference mode of the air conditioning system, and the total power consumption of the air conditioner in the other two operating modes and the reference mode is calculated.

[0041] Step S208: The operating mode with the lowest total power consumption is determined as the target operating mode of the air conditioner under the current outdoor temperature.

[0042] In step S208 above, after determining the total power consumption of the air conditioner in each operating mode, the operating mode with the lowest total power consumption is taken as the target operating mode, so that the air conditioner can operate with the lowest energy consumption under different outdoor temperatures and make the indoor temperature reach the target steady-state temperature, thereby improving the energy-saving effect and cooling efficiency of the air conditioner.

[0043] In this application embodiment, to facilitate understanding of the working mode of the refrigerant pump air conditioning system, a schematic diagram of the working principle of the refrigerant pump air conditioning system is provided, as shown below. Figure 3 As shown, the air conditioning system mainly consists of a compressor, air-cooled condenser, liquid receiver, refrigerant pump, expansion valve, evaporator, check valve, refrigerant pump, and auxiliary components (the refrigerant pump and auxiliary components are not shown in the schematic diagram). Among them, the auxiliary components include exhaust port, copper pipe insulation cotton, check valve, liquid valve, sight glass, dryer filter, and pressure sensor. Compared with the current traditional computer room air conditioning, the refrigerant pump air conditioning system adds a refrigerant pump to the four main components to ensure the system pressure.

[0044] This refrigerant pump air conditioning system has three operating modes: compressor operating mode, refrigerant pump operating mode, and compressor-refrigerant pump hybrid operating mode. Figure 3 As shown, the refrigerant pump and compressor, in conjunction with a check valve, can efficiently and stably switch between three operating modes according to different outdoor weather conditions, providing a comfortable indoor environment. The following combines... Figure 3 These three operating modes will be introduced separately.

[0045] I. Compressor Operation Mode: Under operating conditions with high outdoor temperatures (such as in summer), the air conditioning system adopts compressor operation mode. Specifically, after the refrigerant is compressed by the compressor, it is discharged from the exhaust port and flows to the air-directing condenser. Under the action of the outdoor condenser fan, the outdoor air undergoes forced convection heat exchange, which removes heat and causes the refrigerant to condense. The condensed room-temperature liquid refrigerant flows through the receiver, passes through the one-way valve and the expansion valve, and then enters the evaporator to evaporate, removing the heat from the high-temperature air returning from the server racks in the computer room, thereby obtaining low-temperature air. The refrigerant evaporated in the evaporator encounters hot vapor and is then compressed again by the compressor, thus completing the cycle and realizing the temperature control of the data center computer room by the air conditioning system.

[0046] II. Refrigerant Pump Operation Mode: Under low outdoor temperatures (e.g., winter), the air conditioning system operates in refrigerant pump mode. Specifically: After the refrigerant absorbs heat and evaporates in the evaporator, it becomes superheated vapor. Because the compressor is off and bypassed in refrigerant pump mode, the refrigerant flows into the air-cooled condenser through the bypass check valve. Under the action of the outdoor condenser fan, the outdoor air undergoes forced convection heat exchange, carrying away heat and causing the refrigerant to condense. Due to the low outdoor air temperature in winter, the large heat transfer temperature difference and sufficient and adjustable condensing airflow ensure the condensation effect of the refrigerant. The room-temperature liquid refrigerant after the condenser flows through the receiver. At this time, the refrigerant pump starts, the bypass valve on the refrigerant pump side closes, and the refrigerant pump increases the pressure on the liquid refrigerant, allowing the refrigerant to overcome system resistance and continue flowing forward to complete the cycle without the compressor's involvement. The refrigerant liquid enters the evaporator after passing through the throttling valve and evaporates, exchanging heat with the high-temperature air returning from the server racks in the computer room. The refrigerant vapor after evaporation in the evaporator then enters the air-cooled condenser again through the one-way valve, thus completing the cycle and achieving indoor temperature control of the data center computer room by the air conditioning system.

[0047] III. Compressor-Freon Pump Hybrid Operation Mode: When the outdoor temperature is transitioning between low and high (e.g., spring and autumn), the air conditioning system adopts a compressor-refrigerant pump hybrid operation mode. Specifically: After the refrigerant is compressed by the compressor, it is discharged from the exhaust port and flows to the air-cooled condenser. Under the action of the outdoor condenser fan, the outdoor air undergoes forced convection heat exchange, which carries away the heat and causes the refrigerant to condense. The condensed room-temperature liquid refrigerant flows through the receiver and then enters the refrigerant pump. After being pressurized by the refrigerant pump, the liquid refrigerant becomes a low-pressure refrigerant after passing through the expansion valve. It then exchanges heat again with the high-temperature air flowing out of the indoor cabinets of the computer room. The refrigerant that evaporates in the evaporator is then returned to the air-cooled condenser by the compressor, thus completing the cycle and realizing the indoor temperature control of the data center computer room of the air conditioning system.

[0048] Based on the above three operating modes, after the refrigerant pump air conditioning system is deployed, it will adjust the indoor temperature according to the pre-configured operating mode switching mechanism. For example, the switching mechanism currently configured in most cases is as follows: when the outdoor temperature is less than 10℃, the refrigerant pump operating mode is used; when the outdoor temperature is greater than or equal to 10℃ but less than 20℃, the refrigerant pump-compressor hybrid operating mode is used; and when the outdoor temperature is greater than or equal to 20℃, the compressor operating mode is used. This preset switching mechanism does not fully consider the deployment environment of the air conditioning system and the energy consumption of each operating mode. However, through steps S202 to S208, the current outdoor temperature is obtained; when the indoor temperature reaches the target steady-state temperature, the required cooling capacity of the air conditioner in each operating mode is determined based on the current outdoor temperature and the cooling capacity model, where the cooling capacity model represents the relationship between the outdoor temperature and the cooling capacity of the air conditioner; the operating mode corresponding to the lowest value of cooling capacity is determined as the base mode of the air conditioner, and the total power consumption of the air conditioner in each operating mode is determined based on the current outdoor temperature; the operating mode with the lowest total power consumption is determined as the target operating mode of the air conditioner at the current outdoor temperature. This achieves the goal of determining the most suitable and energy-efficient air conditioning operating mode under different outdoor temperatures, thereby realizing the technical effect of accurately switching the operating mode of the refrigerant pump air conditioning system to reduce system energy consumption. This solves the technical problem that related technologies can only determine the operating mode for refrigerant pump air conditioning systems, which prevents energy saving. The following is a detailed explanation.

[0049] Optionally, the cooling capacity model is determined by: acquiring historical temperature data and historical cooling capacity data within the target area, wherein the historical temperature data includes the historical outdoor temperature of the target area, the historical supply air temperature of the air conditioner, and the historical return air temperature of the air conditioner, and the historical cooling capacity data includes the historical cooling capacity of the air conditioner under different operating modes; and determining the cooling capacity model based on the historical temperature data and historical cooling capacity data.

[0050] In this embodiment, the cooling capacity model is a digital model obtained through experimental data and statistical analysis. It is used to determine the required cooling capacity based on the outdoor temperature under different operating modes. First, historical temperature data of the current deployment area (i.e., the target area) is acquired, which may include parameters such as the highest temperature, lowest temperature, annual average temperature, quarterly average temperature, and temperature duration period. Based on the acquired parameters, the correspondence between historical outdoor temperature, historical air supply temperature of the air conditioner, and historical return air temperature of the air conditioner is obtained through experimental data. The air supply temperature of the air conditioner refers to the temperature of the cold or hot air blown out by the outdoor unit of the air conditioner, and the return air temperature of the air conditioner is the desired indoor temperature. The air conditioning system adjusts the air supply temperature to achieve the desired return air temperature, thereby determining the air supply temperature required to achieve the preset value of the return air temperature.

[0051] Figure 4 This is a schematic diagram illustrating a partial correspondence between outdoor temperature and air conditioning supply air temperature in three operating modes of a refrigerant pump air conditioner according to an embodiment of this application. Figure 4 As can be seen, given the outdoor temperature, the required air supply temperature can be directly determined by combining the current operating mode of the air conditioner. Taking the refrigerant pump operating mode as an example, while maintaining a room temperature (i.e., return air temperature) of 25℃, when the outdoor temperature is -5℃, the required air supply temperature of the air conditioner in refrigerant pump operating mode is 13℃. It should be noted that the return air temperature of the air conditioner remains unchanged in all three operating modes, for example, a constant temperature of 25℃.

[0052] Based on this, the required cooling capacity of the air conditioner can be determined based on the outdoor temperature, thereby establishing a cooling capacity model. Figure 5 This is a schematic diagram illustrating a partial relationship between outdoor temperature and cooling capacity in three operating modes of a refrigerant pump air conditioner according to an embodiment of this application. Figure 5 As can be seen, given the outdoor temperature, the corresponding cooling capacity can be directly calculated by combining the current operating mode of the air conditioner. Taking the refrigerant pump operating mode as an example, when the outdoor temperature is 10℃, the air conditioner needs to output 15000W of cooling capacity to maintain a room temperature of 25℃.

[0053] Optionally, the cooling capacity model includes: when the air conditioner operates in a first operating mode, the cooling capacity model is represented by a first function, wherein the first function includes a first slope and a first intercept, and the value of the first intercept is within a first interval; when the air conditioner operates in a second operating mode, the cooling capacity model is represented by a second function, wherein the second function includes a second slope and a second intercept, the absolute value of the second slope is less than the absolute value of the first slope, and the value of the second intercept is within a second interval; when the air conditioner operates in a third operating mode, the cooling capacity model is represented by a third function, wherein the third function includes a third slope and a third intercept, the absolute value of the third slope is less than the absolute value of the second slope, and the value of the third intercept is within a third interval.

[0054] In this embodiment of the application, under the refrigerant pump operation mode (first operation mode), compressor-refrigerant pump operation mode (second operation mode), and compressor operation mode (third operation mode) of the air conditioning system, the cooling capacity model is expressed in the form of a function, which is described below in conjunction with... Figure 5The functions corresponding to these three modes are explained as follows: In the first operating mode, the first function is y1=a1x+b1, where a1 is the first slope and b1 is the first intercept. The value of the first intercept is within the first interval, i.e., the cooling capacity range corresponding to the refrigerant pump operating mode. In the second operating mode, the second function is y2=a2x+b2, where a2 is the second slope and b2 is the second intercept. The value of the second intercept is within the second interval, i.e., the cooling capacity range corresponding to the compressor-refrigerant pump operating mode. In the third operating mode, the third function is y3=a3x+b3, where a3 is the third slope and b3 is the third intercept. The value of the third intercept is within the third interval, i.e., the cooling capacity range corresponding to the compressor operating mode. It should be noted that the absolute value of the third slope is less than the absolute value of the second slope, and the absolute value of the second slope is less than the absolute value of the first slope.

[0055] Optionally, the total power consumption of the air conditioner in each operating mode is determined based on the current outdoor temperature, including: determining the first total power consumption of the air conditioner in a reference mode when the outdoor temperature changes from the original outdoor temperature to the current outdoor temperature; and determining the second total power consumption of the air conditioner in a non-reference mode when the outdoor temperature changes from the original outdoor temperature to the current outdoor temperature.

[0056] Optionally, determining the first total power consumption of the air conditioner in the baseline mode specifically includes the following steps: obtaining the basic power consumption and basic cooling capacity of the air conditioner in the baseline mode and at the original outdoor temperature; when the outdoor temperature changes from the original outdoor temperature to the current outdoor temperature, determining the target energy efficiency ratio and target cooling capacity of the air conditioner at the current outdoor temperature based on the energy efficiency ratio model and the cooling capacity model, wherein the energy efficiency ratio model is used to characterize the relationship between the energy efficiency ratio, outdoor temperature, and power of the air conditioner in different operating modes, and the energy efficiency ratio is determined by the cooling capacity and power; determining the supplementary power consumption of the air conditioner in the baseline mode and at the current outdoor temperature based on the difference between the target energy efficiency ratio and the target cooling capacity, wherein the difference in target cooling capacity is the absolute value of the difference between the target cooling capacity and the basic cooling capacity; and determining the first total power consumption based on the basic power consumption and the supplementary power consumption.

[0057] The following combination Figure 6 The above process will be explained in the embodiments of this application. Figure 6 This is a schematic diagram illustrating a partial correspondence between the power and energy efficiency ratio of a refrigerant pump air conditioner and the outdoor temperature under different outdoor temperatures, according to an embodiment of this application. Figure 5 and Figure 6 This allows us to determine the first total power consumption of the air conditioner in baseline mode, specifically: based on Figure 6 To obtain the reference power of the air conditioner under the original outdoor temperature and reference mode, for example, when the original outdoor temperature is 5℃ and the reference mode is the refrigerant pump operation mode, it can be based on... Figure 6The baseline power is set at 4000W. Based on the air conditioner's operating time in baseline mode at the original outdoor temperature, the basic power consumption of the air conditioner in baseline mode at the original outdoor temperature can be determined according to the baseline power and corresponding operating time. Figure 5 This allows you to determine the basic cooling capacity of the air conditioner at the initial outdoor temperature. As the outdoor temperature increases from 5°C to 10°C, i.e., the current outdoor temperature becomes 10°C, the capacity is determined according to... Figure 6 and Figure 5 The target energy efficiency ratio (EER) and target cooling capacity of the air conditioner at the current outdoor temperature can be determined. The difference between the target cooling capacity and the baseline cooling capacity can be used to determine the target cooling capacity difference. Substituting this difference and the target EER into the EER formula, the supplementary power required for the air conditioner to operate when the outdoor temperature increases from 5°C to 10°C can be determined. The supplementary power consumption can be determined based on the supplementary power and the operating time required for the air conditioner to reach the required indoor temperature at that supplementary power. Here, EER = Cooling Capacity / Power. The sum of the baseline power consumption and the supplementary power consumption determines the first total power consumption of the air conditioner in the baseline mode and at the current outdoor temperature. For example, based on the cooling capacity model, taking the refrigerant pump operation mode as an example, as the outdoor temperature increases from 5°C to 10°C, the cooling capacity output by the refrigerant pump operation mode gradually decreases and is far lower than the cooling capacity output by the compressor-refrigerant pump hybrid operation mode. Assuming the baseline power consumption in the refrigerant pump mode is A when the outdoor temperature is 5°C, and the supplementary power consumption in the refrigerant pump mode is B when the temperature increases from 5°C to 10°C, then the first total power consumption in this refrigerant pump mode is A + B.

[0058] Optionally, the second total power consumption of the air conditioner in non-baseline mode is determined, specifically including the following steps: determining the second total power consumption of the air conditioner in the current outdoor temperature and non-baseline mode based on the energy efficiency ratio model.

[0059] In this embodiment of the application, based on the energy efficiency ratio model, the second total power consumption of the air conditioner in non-baseline mode is obtained. If the baseline mode is the refrigerant pump operation mode, the non-baseline mode includes the compressor-refrigerant pump hybrid operation mode and the compressor operation mode, for example: based on Figure 6 Taking the compressor-refrigerant pump hybrid operation mode as a non-baseline mode as an example, it can be determined that when the outdoor temperature increases from 5℃ to 10℃, that is, when the current outdoor temperature is 10℃, the second power of the compressor-refrigerant pump hybrid operation mode itself is known. Based on the second power and the running time of the air conditioner to reach the required indoor temperature under the second power, the second total power consumption can be determined, and the second total power consumption can be denoted as C.

[0060] Optionally, determining the operation mode with the lowest total power consumption as the target operation mode of the air conditioner at the current outdoor temperature includes: comparing a first total power consumption and a second total power consumption; when the first total power consumption is greater than the second total power consumption, determining the operation mode corresponding to the second total power consumption as the target operation mode; when the first total power consumption is less than or equal to the second total power consumption, determining the operation mode corresponding to the first total power consumption as the target operation mode.

[0061] In the embodiments of the present application, after determining the total power consumption of the air conditioner under different operation modes, the operation mode with the lowest total power consumption is taken as the target operation mode, so that the air conditioner can operate at the optimal low energy consumption under different outdoor temperatures, thereby improving the energy saving effect and refrigeration efficiency of the air conditioner. Specifically: comparing the first total power consumption and the second total power consumption; when the first total power consumption is greater than the second total power consumption, determining the operation mode corresponding to the second total power consumption as the target operation mode; when the first total power consumption is less than or equal to the second total power consumption, determining the operation mode corresponding to the first total power consumption as the target operation mode. For example: in the above operation, when the current outdoor temperature changes from 5°C to 10°C, if A+B>C, the compressor-fluorine pump hybrid operation mode is determined as the target operation mode of the air conditioner; if A+B<C, the fluorine pump operation mode is determined as the target operation mode of the air conditioner.

[0062] In the embodiments of the present application, by acquiring the current outdoor temperature; determining the required refrigeration capacity of the air conditioner under each operation mode according to the current outdoor temperature and a refrigeration capacity model, wherein the refrigeration capacity model is used to represent the relationship between the outdoor temperature and the refrigeration capacity of the air conditioner; determining the operation mode corresponding to the minimum value of the refrigeration capacity as the reference mode of the air conditioner, and determining the total power consumption of the air conditioner under each operation mode according to the current outdoor temperature; determining the operation mode with the lowest total power consumption as the target operation mode of the air conditioner, the purpose of determining the most suitable air conditioner operation mode with the lowest energy consumption under different outdoor temperatures is achieved, thereby realizing the technical effect of accurately switching the operation mode of the fluorine pump air conditioning system to reduce the system energy consumption, and further solving the technical problem that energy saving cannot be achieved because the related art can only determine the operation mode for the fluorine pump air conditioning system.
