The data center comprises machine room equipment and a machine room air conditioner, and the dynamic loop monitoring system adjusts the output of the machine room air conditioner, so that the change of the ambient temperature of the machine room is realized, and the machine room equipment is guaranteed to operate in the ambient temperature with optimal efficiency. The execution main body in the embodiment of the present invention may be a dynamic ring monitoring system, or a module or a device for control in other data centers, which may be specifically selected according to actual situations, and the present invention is not described herein again.
In order to improve the precision of adjusting the refrigerating capacity of the air conditioner in the machine room in the data center, the embodiment of the invention provides a control method for adjusting an empty machine room. Referring to fig. 1, an implementation flowchart of a control method for a machine room air conditioner provided by an embodiment of the present invention is shown. As shown in fig. 1, a control method of a machine room air conditioner may include:
and S101, acquiring the total load of the machine room equipment of the data center.
Optionally, the equipment in the equipment room may be an it (information technology) load of the data center, and the total load of the equipment in the equipment room may be the sum of the loads of all the equipment in the data center. The total load of the machine room equipment can be rapidly acquired through the dynamic loop monitoring system, and the total load of the machine room equipment can comprise numerical values of all periods. For example, the total load amount may include a total load amount of a current cycle and a total load amount of a previous cycle.
And S102, calculating the absolute value of the difference value between the total refrigerating capacity and the total load capacity of the air conditioner in the machine room.
Optionally, the absolute value of the difference between the total cooling capacity and the total load capacity may be used to represent the adjusting capacity of the machine room air conditioner to the machine room equipment.
Optionally, the total cooling capacity of the air conditioner in the machine room can be directly obtained through the dynamic loop monitoring system. The total refrigerating capacity of the air conditioners in the machine room can be the refrigerating capacity of all the air conditioners in the data center. Or, the calculation result is obtained through the calculation of the relevant working parameters of the air conditioner in the machine room. For example, the total cooling capacity of the air conditioner in the machine room can be calculated according to a ten-coefficient model of the compressor.
Specifically, before obtaining the total load of the machine room air conditioners in the data center, the method may further include: acquiring working parameters of a machine room air conditioner; and calculating the total refrigerating capacity of the air conditioner in the machine room according to the working parameters based on a ten-coefficient model of the compressor.
Optionally, the operating parameters of the air conditioner in the machine room may include evaporation temperature, condensation temperature, and the like.

As shown in fig. 2, the air conditioner for a machine room includes key components and sensors, and the key components include: a variable frequency compressor, an oil separator, a condenser, a dry filter, a liquid sight glass, an electronic expansion valve (throttling component), an evaporator and the like. The sensor includes: an exhaust temperature sensing bulb, a high-pressure sensor, a low-pressure sensor, an air return temperature sensing bulb, a condenser outlet temperature sensing bulb, an outdoor environment temperature T4 and the like.
In the simulation calculation, a compressor model is required in calculating the parameters of the refrigeration system. The more the compressor model reflects the parameters of the actual compressor, the more accurate the simulation calculation. The compressor manufacturer may also utilize a compressor mathematical model to program the model selection software in order to provide the customer with an accurate reference for the model selection of the compressor.
A polynomial equation of degree is typically used to create a mathematical model of the compressor parameters. The more the degree of the polynomial is, the higher the accuracy of the corresponding mathematical model is, but the larger the calculation amount is. Therefore, it is common practice to use cubic polynomials to build a mathematical model of the compressor, which can ensure the calculation accuracy and reduce the calculation amount.

The input power, mass flow, current, and energy efficiency of the compressor under standard conditions (e.g., 15 ° f subcooling, 20 ° f superheat) can all be represented by this mathematical model. Wherein: c 1 ～C 10 Ten coefficients are represented. TCD, TEV represent the condensation and evaporation temperatures, respectively, in degrees Fahrenheit (or deg.C). X may represent: refrigerating capacityW (or KW); input power W (or KW); mass flow Kg/s (or lbs/h); current, A; energy efficiency ratio, W/W (or Btu/(hw)). The units of the various parameters in equation (1) depend on the units of the raw data used to fit the equation.
The parameters at the specific evaporating temperature and condensing temperature of the compressor can be obtained by the formula (1) and the known corresponding 10 coefficients. The evaporating temperature and the condensing temperature are obtained by reading a high-pressure sensor and a low-pressure sensor of the machine room air conditioner to convert the saturated temperature.
The dynamic loop monitoring system collects data of equipment in the machine room, reads a high-pressure sensor and a low-pressure sensor of the air conditioner in the machine room to convert evaporation temperature and condensation temperature, obtains a compressor ten-coefficient model of the air conditioner in the machine room used in the data center in advance through a compressor manufacturer, and simulates and calculates parameters of real refrigerating capacity, input power and energy efficiency of the air conditioner in the machine room so as to obtain the total refrigerating capacity of the air conditioner in the machine room.

When the difference value, namely the absolute value, is not greater than the first preset value, the difference between the total refrigerating capacity and the total load capacity is not large, the total refrigerating capacity and the total load capacity can be matched through the preset automatic adjustment rule of the air conditioner or the current air conditioner of the machine room, and the working efficiency of equipment of the machine room is optimal. When the absolute value of the difference value is larger than a first preset value, the difference between the total refrigerating capacity and the total load capacity is larger, the operation requirement of the machine room equipment is difficult to meet through an automatic regulation rule preset by the machine room air conditioner or the current machine room air conditioner is not regulated, and at the moment, a regulation strategy of the machine room air conditioner is required to be determined according to the first difference value between the current cycle total load capacity of the machine room equipment and the last cycle total load capacity of the machine room equipment so as to ensure that the machine room equipment works at the optimal efficiency.

When the first difference is not in the first preset range, the output refrigerating capacity of the air conditioner in the running state is increased or decreased, and the requirement of the refrigerating capacity of the equipment in the machine room is difficult to meet. At this time, the adjustment strategy can be determined according to the total load of the current period of the equipment in the machine room. For example, the number of air conditioners in an operating state may be increased or the number of air conditioners in an operating state may be decreased so that the total cooling capacity matches the total load capacity.
Optionally, the first preset range may be used to represent a threshold value of the adjusting capability of the air conditioner in the operating state, or represent a normal variation range of the total load of the equipment in the machine room. When the first difference value is within a first preset range, the operation number of the air conditioners in the whole machine room can be not adjusted; when the first difference is not within the first preset range, the operation number of the air conditioners in the machine room needs to be adjusted.

The selection can be specifically carried out according to the actual situation.
For example, when the first difference value is higher than the first preset range, the number of air conditioners in an operation state may be increased. When the first difference is lower than the first preset range, the number of air conditioners in an operating state may be reduced.
And S1032, when the first difference value is within a first preset range, determining an adjusting strategy according to a second difference value of the total refrigerating capacity and the total load capacity of the machine room air conditioners.
Optionally, when the first difference is within a first preset range, it indicates that the cooling capacity requirement of the equipment in the equipment room can be met by increasing or decreasing the output cooling capacity of the air conditioner in the running state. At this time, the adjusting strategy may be determined according to a second difference between the total cooling capacity and the total load capacity of the air conditioners in the machine room. For example, the output cooling capacity of the room air conditioner in the operating state is increased or decreased.
Optionally, the second difference is used to indicate a degree of difference between the total cooling capacity and the total load capacity. The absolute value of the second difference is generally greater than the first preset value. The first preset range can be determined according to the matching condition of the total refrigerating capacity of the historical machine room air conditioner and the total load of the historical machine room equipment, and can also be determined according to the matching condition of the total refrigerating capacity of the simulated machine room air conditioner and the total load of the simulated machine room equipment. The selection can be specifically carried out according to the actual situation.
According to the embodiment of the invention, the adjustment strategy of the air conditioner in the machine room which is not used is determined by comparing the first difference with the first preset range, so that the adjustment precision of the air conditioner in the machine room can be greatly improved, the total load of equipment in the machine room can be matched better, and the power consumption of the data center can be reduced.

And when the first difference is larger than or equal to the upper limit value of the first preset range, selecting a second number of air conditioners in the dormant state, and controlling the second number of air conditioners in the dormant state to be switched into the running state.
Optionally, when the total load of the equipment in the machine room changes too much, the output refrigerating capacity of the air conditioner in the running state is adjusted to be difficult to meet the working requirement of the equipment in the machine room, and at the moment, the air conditioner in the running state needs to be increased or decreased so as to meet the working temperature requirement of the equipment in the machine room. For example, a first number of air conditioners in the operating state are controlled to be switched to the dormant state, or a second number of air conditioners in the dormant state are controlled to be switched to the operating state, so that the total cooling capacity of the adjusted air conditioners in the machine room meets the working requirement of the equipment in the machine room. The second preset range can be set according to actual conditions.

According to the embodiment of the invention, the operation quantity of the machine room air conditioners is controlled in a stepped manner, different increasing strategies are adopted under different conditions, the adjusting time of the machine room air conditioners can be shortened, the matching efficiency of the total refrigerating capacity of the machine room air conditioners and the total load capacity of the machine room equipment is effectively improved, the working efficiency of the machine room equipment is improved, and the consumption of electric power energy is reduced.
In some embodiments of the present invention, the "determining an adjustment strategy according to the second difference between the total cooling capacity and the total load capacity of the air conditioners in the machine room" in S1032 may include:
and if the second difference is larger than the upper limit value of the second preset range, or the second difference is smaller than the lower limit value of the second preset range, adjusting the total refrigerating capacity of the air conditioner in the machine room to be in the second preset range.
Optionally, the second preset range is used for representing a reasonable refrigerating capacity range output by the currently operating machine room air conditioner for matching the working ambient temperature of the machine room equipment, and the second preset range may be determined according to an actual situation. For example, the second preset range may be determined according to a matching condition of the total cooling capacity of the historical machine room air conditioners and the total load capacity of the historical machine room devices, or may be determined according to a matching condition of the total cooling capacity of the simulated machine room air conditioners and the total load capacity of the simulated machine room devices. Can be selected according to actual conditions
Specifically, if the second difference is larger than the upper limit value of the second preset range, the total refrigerating capacity of the air conditioner in the machine room is adjusted to be reduced to the second preset range; and if the second difference is smaller than the lower limit value of the second preset range, adjusting the total refrigerating capacity of the air conditioner in the machine room to rise to the second preset range.
The second difference value is larger than the upper limit value of the second preset range, which indicates that the total refrigerating capacity of the air conditioner in the machine room is larger than the total load capacity of the equipment in the machine room, that is, the refrigerating capacity output of the air conditioner is too high, so that the ambient temperature of the data center is lower than the optimal ambient temperature of the equipment in the machine room, the total refrigerating capacity can be reduced, and the ambient temperature of the data center is guaranteed to be increased to the optimal ambient temperature of the equipment in the machine room.
The lower limit value that the second difference is less than the first preset range shows that the total refrigerating capacity of room air conditioners is less than the total load capacity of the equipment in the machine room, that is, the output of the refrigerating capacity of the air conditioners is too low, so that the ambient temperature of the data center is higher than the optimal ambient temperature of the equipment in the machine room, and therefore the total refrigerating capacity can be improved, and the ambient temperature of the data center is reduced to the optimal ambient temperature of the equipment in the machine room.
According to the embodiment of the invention, the total refrigerating capacity is matched with the total load capacity, so that the equipment in the machine room works at the environment temperature corresponding to the optimal efficiency, and the data processing efficiency of the equipment in the machine room of the data center can be improved.
In addition, in many data centers, the capacity of the air conditioner in the machine room is managed by reading the product of the output percentage of the compressor of the air conditioner and the rated refrigerating capacity of the air conditioner to express the capacity of the air conditioner in the machine room, so that the estimated deviation of the refrigerating capacity of the air conditioner is large, the real refrigerating capacity of the data center cannot be accurately reflected, and the refrigerating capacity management cannot be effectively performed.
In order to solve the problems, the embodiment of the invention calculates the total refrigerating capacity of the air conditioner in the machine room by adopting a compressor-based ten-coefficient model, and makes up for the defect that the air conditioner in the machine room cannot read the load capacity; the delay condition of the machine room air conditioner for sensing the load temperature is improved; the air conditioner in the machine room can quickly respond to the change of the load and stably operate. PUE (Power Usage Effect) can be reduced by 0.02 on a par.
