Referring to fig. 2, fig. 2 is a flow chart of an anti-freezing control method for a refrigeration system of a data center according to the above embodiment, as shown in fig. 2, according to an embodiment of the present invention, the method includes the following steps:
step 102: and determining the operation type of the pipeline to be prevented from freezing.
Step 104: and according to the anti-freezing strategy corresponding to the pipeline to be frozen in each operation type, freezing the pipeline to be frozen.
In the embodiment of the invention, the operation type of the pipeline to be antifreezed can be determined.
In one embodiment, the type of operation of the pipe to be freeze protected may include long term operation as well as intermittent operation.
In one example, the pipe to be freeze protected may be a pipe in a data center refrigeration system, for example, a pipe in an outdoor piping system in a data center refrigeration system. When the pipe to be freeze-protected is the first pipe, it may be determined that the operation type of the pipe to be freeze-protected is long-term operation. The first pipe may include at least a cooling tower water supply pipe (may also be referred to as a cooling water supply pipe), an outdoor humidification pipe, and a cooling tower balance pipe. In this example, the cooling tower balancing pipe may include a cooling tower balancing pipe branch pipe and a cooling tower balancing pipe main pipe; the outdoor humidification pipe may be an outdoor humidification main pipe.
When the pipe to be freeze-protected is the second pipe, it may be determined that the operation type of the pipe to be freeze-protected is intermittent operation, wherein the second pipe may include at least a cooling tower backup apparatus pipe, a cooling tower overflow pipe, a cooling tower drain pipe (may also be referred to as a cooling water drain pipe), a chilled water outdoor pipe, and a cooling water outdoor pipe. In this example, the cooling tower backup apparatus pipe may be specifically a cooling tower backup apparatus water inlet and outlet branch pipe; the cooling tower overflow pipe can be a cooling tower overflow branch pipe; the cooling tower drainage pipeline can be a main cooling tower drainage pipe; the chilled water outdoor pipeline can be a chilled water outdoor main loop pipe or a vertical pipe; the cooling water outdoor pipeline can be a cooling water outdoor main loop pipe or a stand pipe.
After determining the operation type of the pipeline to be frozen, the pipeline to be frozen can be frozen according to the freezing prevention strategy corresponding to the pipeline to be frozen of each operation type.
In this embodiment, when the pipeline to be prevented from being caused by the electric tracing operation mode being started.
In this embodiment, the anti-freezing strategies corresponding to the to-be-frozen pipelines of different operation types may be different or the same, which is not limited in this embodiment.
In one embodiment, the corresponding anti-freeze strategy for the pipeline to be anti-freeze, whose operation type is long-term operation, may be: and when the temperature in the pipeline to be frozen is lower than a preset threshold value, freezing the pipeline to be frozen.
In one example, a temperature sensor may be provided within the pipe to be freeze protected to monitor the temperature within the pipe to be freeze protected.
For example, the preset threshold may be 5 ℃, and the anti-freezing policy corresponding to the pipeline to be anti-frozen, the operation type of which is long-term operation, may be: and when the temperature in the pipeline to be frozen is lower than 5 ℃, freezing the pipeline to be frozen. The pipeline to be freeze-protected, which is operated for a long period of time, can then be freeze-protected according to the freeze protection strategy.
For example, the monitored temperature in the pipe to be freeze-protected may be 3 ℃, and it may be determined to freeze the pipe to be freeze-protected according to the freeze-protection strategy described above.
In this embodiment, the anti-freezing policy corresponding to the pipeline to be frozen, where the operation type is long-term operation, may further include: and when the temperature in the pipeline to be frozen is not lower than the preset threshold value, not freezing the pipeline to be frozen.
For example, the preset threshold may be 5 ℃, and the temperature in the pipeline to be frozen may be 6 ℃, and it may be determined that the pipeline to be frozen is not frozen according to the above-mentioned freezing prevention strategy.
In one embodiment, the corresponding anti-freezing strategy for the pipeline to be anti-frozen, the operation type of which is intermittent, may be: when water flows in the pipeline to be frozen, the pipeline to be frozen is frozen.
In one example, whether there is water flow in the pipe to be freeze-protected may be monitored by a water flow sensor, which may be disposed in the pipe to be freeze-protected or on a valve connected to the pipe to be freeze-protected, which is not limited in this example.
For example, the water flow sensor monitors that the water flow exists in the pipeline to be prevented from being frozen, it may be determined to freeze the pipe to be freeze protected according to the freeze protection policy.
In this embodiment, the anti-freezing policy corresponding to the pipeline to be frozen, where the operation type is intermittent, may further include: when no water flow exists in the pipeline to be frozen, the pipeline to be frozen can not be frozen.
For example, if no water flow in the pipeline to be prevented from being prevented is monitored by the water flow sensor, the pipeline to be prevented from being prevented according to the anti-freezing strategy.
In another embodiment, the pipeline to be freeze protected, which is operated in an intermittent manner, may comprise a plurality of functionally different pipeline sections. In one example, the functionally different pipe sections may be obtained in advance according to the function of the pipe to be freeze-protected, which is operated intermittently according to the type of operation.
The corresponding anti-freeze policy for an anti-freeze pipe with an intermittent operation type may correspond to: and freezing the pipeline sections with water flow in the pipeline sections. At this time, the pipe section having no water flow among the plurality of pipe sections may not be subjected to freezing prevention.
For example, the pipeline 1 to be freeze-protected, which is operated in a batch mode, may comprise 4 pipeline sections: a pipe section 11, a pipe section 12, a pipe section 13 and a pipe section 14, wherein the pipe section 11, the pipe section 12, the pipe section 13 and the pipe section 14 are different in function; the pipe section 11 and the pipe section 12 have water flow therein; there is no water flow in the pipe sections 13 and 14. The corresponding anti-freezing strategy of the pipeline 1 to be frozen can be as follows: the pipe sections 11, 12, 13 and 14 are freeze protected from water. The pipe section 11 as well as the pipe section 12 can be defrosted when the antifreeze is carried out according to the antifreeze strategy corresponding to the pipe 1 to be defrosted. At this time, the pipe section 13 and the pipe section 14 may not be subjected to freezing prevention.
As is clear from the above, in the present embodiment, the operation type of the pipe to be freeze-prevented may be determined, and then the pipe to be freeze-prevented may be freeze-prevented according to the freeze-preventing policy corresponding to the pipe to be freeze-prevented of each operation type.
The pipeline to be frozen can be frozen according to the freezing strategy corresponding to the operation type of the pipeline to be frozen, so that when the pipeline to be frozen is frozen, the pipeline to be frozen can be frozen in a distinguishing and intelligent mode, and as the pipeline to be frozen is not uniformly frozen any more, the pipeline to be frozen can be frozen in a distinguishing and intelligent mode, the freezing efficiency can be effectively improved, and freezing can be effectively realized in an energy-saving mode.

In the 90 s of the 20 th century, improvements to one technology could clearly be distinguished as improvements in hardware (e.g., improvements to circuit structures such as diodes, transistors, switches, etc.) or software (improvements to the process flow). However, with the development of technology, many improvements of the current method flows can be regarded as direct improvements of hardware circuit structures. Designers almost always obtain corresponding hardware circuit structures by programming improved method flows into hardware circuits. Therefore, an improvement of a method flow cannot be said to be realized by a hardware entity module. For example, a programmable logic device (Programmable Logic Device, PLD) (e.g., field programmable gate array (Field Programmable Gate Array, FPGA)) is an integrated circuit whose logic function is determined by the programming of the device by a user. A designer programs to "integrate" a digital system onto a PLD without requiring the chip manufacturer to design and fabricate application-specific integrated circuit chips. Moreover, nowadays, instead of manually manufacturing integrated circuit chips, such programming is mostly implemented by using "logic compiler" software, which is similar to the software compiler used in program development and writing, and the original code before the compiling is also written in a specific programming language, which is called hardware description language (Hardware Description Language, HDL), but not just one of the hdds, but a plurality of kinds, such as ABEL (Advanced Boolean Expression Language), AHDL (Altera Hardware Description Language), confluence, CUPL (Cornell University Programming Language), HDCal, JHDL (Java Hardware Description Language), lava, lola, myHDL, PALASM, RHDL (Ruby Hardware Description Language), etc., VHDL (Very-High-Speed Integrated Circuit Hardware Description Language) and Verilog are currently most commonly used. It will also be apparent to those skilled in the art that a hardware circuit implementing the logic method flow can be readily obtained by merely slightly programming the method flow into an integrated circuit using several of the hardware description languages described above.
The controller may be implemented in any suitable manner, for example, the controller may take the form of, for example, a microprocessor or processor and a computer readable medium storing computer readable program code (e.g., software or firmware) executable by the (micro) processor, logic gates, switches, application specific integrated circuits (Application Specific Integrated Circuit, ASIC), programmable logic controllers, and embedded microcontrollers, examples of which include, but are not limited to, the following microcontrollers: ARC 625D, atmel AT91SAM, microchip PIC18F26K20, and Silicone Labs C8051F320, the memory controller may also be implemented as part of the control logic of the memory. Those skilled in the art will also appreciate that, in addition to implementing the controller in a pure computer readable program code, it is well possible to implement the same functionality by logically programming the method steps such that the controller is in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers, etc. Such a controller may thus be regarded as a kind of hardware component, and means for performing various functions included therein may also be regarded as structures within the hardware component. Or even means for achieving the various functions may be regarded as either software modules implementing the methods or structures within hardware components.
The system, apparatus, module or unit set forth in the above embodiments may be implemented in particular by a computer chip or entity, or by a product having a certain function. One typical implementation is a computer. In particular, the computer may be, for example, a personal computer, a laptop computer, a cellular telephone, a camera phone, a smart phone, a personal digital assistant, a media player, a navigation device, an email device, a game console, a tablet computer, a wearable device, or a combination of any of these devices.
For convenience of description, the above devices are described as being functionally divided into various units, respectively. Of course, the functions of each element may be implemented in the same piece or pieces of software and/or hardware when implementing the present invention.
It will be appreciated by those skilled in the art that embodiments of the present invention may be provided as a method, system, or computer program product. Accordingly, the present invention may take the form of an entirely hardware embodiment, an entirely software embodiment or an embodiment combining software and hardware aspects. Furthermore, the present invention may take the form of a computer program product embodied on one or more computer-usable storage media (including, but not limited to, disk storage, CD-ROM, optical storage, and the like) having computer-usable program code embodied therein.
The present invention is described with reference to flowchart illustrations and/or block diagrams of methods, apparatus (systems) and computer program products according to embodiments of the invention. It will be understood that each flow and/or block of the flowchart illustrations and/or block diagrams, and combinations of flows and/or blocks in the flowchart illustrations and/or block diagrams, can be implemented by computer program instructions. These computer program instructions may be provided to a processor of a general purpose computer, special purpose computer, embedded processor, or other programmable data processing apparatus to produce a machine, such that the instructions, which execute via the processor of the computer or other programmable data processing apparatus, create means for implementing the functions specified in the flowchart flow or flows and/or block diagram block or blocks.
These computer program instructions may also be stored in a computer-readable memory that can direct a computer or other programmable data processing apparatus to function in a particular manner, such that the instructions stored in the computer-readable memory produce an article of manufacture including instruction means which implement the function specified in the flowchart flow or flows and/or block diagram block or blocks.
These computer program instructions may also be loaded onto a computer or other programmable data processing apparatus to cause a series of operational steps to be performed on the computer or other programmable apparatus to produce a computer implemented process such that the instructions which execute on the computer or other programmable apparatus provide steps for implementing the functions specified in the flowchart flow or flows and/or block diagram block or blocks.
In one typical configuration, a computing device includes one or more processors (CPUs), input/output interfaces, network interfaces, and memory.
The memory may include volatile memory in a computer-readable medium, random Access Memory (RAM) and/or nonvolatile memory, such as Read Only Memory (ROM) or flash memory (flash RAM). Memory is an example of computer-readable media.
