Description

Technical Field

[0001] The present invention relates to the field of intelligent monitoring devices for intelligent manufacturing equipment, and in particular to a standard and efficient computer room operation and maintenance monitoring system and method. Background Art

[0002] With the progress of society and the continuous advancement of urbanization, people have gradually focused their attention on the construction and renovation of central air-conditioning rooms. In areas with hot summers and warm winters, the energy consumption of air-conditioning systems in public buildings accounts for 30% to 50%, and the energy consumption of refrigeration hosts, water pumps, and cooling towers accounts for about 70% of the building energy consumption. Therefore, energy conservation in air-conditioning systems has become the focus and core of building energy conservation. At present, the energy efficiency ratio (EER) of the air-conditioning rooms of enterprises is generally around 3.2, and the energy-saving potential is huge. Therefore, the application of standard high-efficiency computer rooms is of great significance to saving energy, maintaining a good ecological environment, promoting green technology innovation, and promoting the green transformation of production and lifestyle.

[0003] However, the transformation of the air-conditioning room requires a complete operation and maintenance monitoring system and a set of appropriate operation and maintenance methods. At present, the operation and maintenance monitoring system and operation and maintenance methods of the room still have the following shortcomings:

[0004] (1) Failure to fully combine and apply feedforward and feedback techniques.

[0005] Feedforward technology requires analysis of relatively stable data, such as power consumption, cooling capacity, etc., while feedback technology requires parameter feedback of each structure of the standard high-efficiency computer room, such as pressure, temperature, etc., to judge the stability of the operation of the standard high-efficiency computer room. At present, the feedforward and feedback technologies are mainly combined to improve personnel comfort and air conditioning energy saving, and the troubleshooting function is ignored to a certain extent. For example, China's public patent CN113945001A controls the variable air volume control box in a certain area in real time by sensing the behavior and number of people in a certain area, and controls the temperature of each air-conditioning area. Adjusting the terminal temperature setting value and air supply volume through the air conditioning load generated by personnel is a single control method, which does not involve the control of the entire standard university computer room, and cannot detect abnormal operation of the equipment based on parameter changes.

[0006] (2) Failure to extend local control to the intelligent control of the entire standard high-efficiency computer room.

[0007] The improvement of energy efficiency of standard high-efficiency computer rooms is reflected in the increase in the proportion of power consumption of the refrigeration host. If some structures are frequency-controlled, energy efficiency can be improved to a certain extent and energy-saving effects can be achieved. For example, China's public patent CN110160230A controls the operating frequency of the water pump through the feedback of the air-conditioning water system load, and China's public patent CN110398034A controls the operation of the cooling tower through the feedback of the temperature difference and the target operating frequency of the fan. However, the above patent scheme only controls a certain structure through feedback signals, which cannot fully utilize the feedforward technology and ignores the role of feedback technology in equipment operation and maintenance.

[0008] (3) Failure to combine the system design and operation and maintenance methods of standard and efficient computer rooms for unified management.

[0009] The construction of a standard and efficient computer room includes the unification of five systems: the selection of air-conditioning equipment, optimized design, stable group control system, installation and construction, and intelligent debugging and operation and maintenance. Improving and innovating some of these systems can effectively improve the efficiency of the construction of a standard and efficient computer room. For example, the model pre-matching method and system proposed in the Chinese patent CN114329684A can effectively improve the refinement of the BIM model in the optimization design system. The Chinese patent CN112665443A sets the preset temperature value by feedforward to adjust the wind speed of the cooling tower fan in real time, thereby improving the overall cooling efficiency of the refrigeration room in the group control system and the debugging and operation and maintenance system. However, the above patent solution only optimizes and upgrades one or two of the five systems in the construction of a standard and efficient computer room. While it cannot guarantee mutual compatibility, it is also not conducive to the unified management of the builder. Summary of the invention

[0058] In some embodiments of the present invention, a standard and efficient computer room operation and maintenance method is also provided, which is implemented based on the above-mentioned standard and efficient computer room operation and maintenance monitoring system. Figure 2 , the method comprises the following steps:

[0059] Step S1 , predicting the annual heat load, annual cooling capacity, annual power consumption of the building and the expected EER and COP parameters of the standard high-efficiency computer room through the working data of the terminal operation module 50 .

[0060] In this step, the annual heat load, annual cooling capacity, annual power consumption acceptable to the enterprise and the expected EER and COP parameters of the standard high-efficiency computer room are adjusted through the feedback of step S6.

[0061] Step S2, determining the selection of the cooling tower operation module 10, the cooling water pump control module 20, the host operation module 30, the chilled water pump control module 40 and the terminal operation module 50 according to the annual heat load, annual cooling capacity, annual power consumption, and the expected EER and COP parameters of the standard high-efficiency computer room;

[0062] Determine the selection, including determining the cooling capacity of the cooling tower and main unit, the speed of each water pump, etc.

[0063] In this step, the cooling tower operation module 10, the cooling water pump control module 20, the main operation module 30, the chilled water pump control module 40 and the terminal operation module 50 are arranged and designed through BIM technology. That is, after the selection is determined, the standard and efficient computer room operation and maintenance monitoring system is constructed in combination with the construction scenario in the BIM modeling software.

[0064] Step S3 , setting initial operating parameters of the cooling tower 11 , the first cooling water pump 21 and the second cooling water pump 22 , the first host 31 and the second host 32 , and the first chilled water pump 41 and the second chilled water pump 42 .

[0065] The initial working parameters include but are not limited to: the chilled water outlet temperature of each host, the frequency of each water pump, the frequency of each cooling tower fan, and the most unfavorable pressure difference.

[0066] In this step, through the online monitoring device 61, feedforward control is used to set the temperature parameters in the first host 31 and the second host 32, and the operating frequencies of the cooling tower 11, the first cooling water pump 21 and the second cooling water pump 22, the first host 31 and the second host 32, and the first chilled water pump 41 and the second chilled water pump 42 are set within a certain range, and the standard high-efficiency machine room is installed and constructed.

[0068] By collecting parameters such as EER and cooling capacity in real time, it is determined whether the requirements of an efficient computer room have been met. For example, if EER is set to be greater than 5.0, the parameters of each cooling tower, main unit, and water pump are adjusted to maintain a high EER, even if EER is greater than 5.0.

[0069] Step S5, through the sensors and online monitoring device 61, if there is an alarm or parameter error, the parameter error is fault diagnosed and possible faults are checked, and then the process returns to step S4; if not, the system runs to step S6.

[0071] Step S6, collecting the working data of the terminal operation module 50, and then repeating steps S3 to S5.

[0072] In this step, by collecting the working data of the terminal operation module 50, such as the terminal heat load, total power consumption, total cooling capacity, system load rate, cooling capacity, heat dissipation, total power, system energy efficiency, host efficiency, thermal balance rate, chilled water energy delivery coefficient, cooling water pump delivery coefficient, cooling tower delivery coefficient, etc., the energy efficiency ratio EER parameter and COP parameter values ​​of the standard high-efficiency computer room can be reflected in real time, and the parameters of the cooling tower, host, and water pump can be adjusted accordingly during the peak and trough periods of central air-conditioning use to achieve the maximum energy saving effect.
