Description

Technical Field

[0001] The present disclosure relates to the field of automated processing technology, and in particular to a method for controlling air supply temperature, an apparatus for controlling air supply temperature, an electronic device, and a computer program product. Background Art

[0002] Fluorine pump refrigeration technology is a thermal management solution that uses fluoride as a phase change cooling medium. It is widely used in data centers and high-performance computing. Its core principle is to utilize the phase change characteristics of fluorine refrigerants to achieve efficient heat transfer through conversion between liquid and gas.

[0003] As a prefabricated air conditioner with large particles, the fluorine pump integrated machine can provide data centers with larger cooling capacity and more convenient equipment refrigeration applications. The equipment assembles indoor and outdoor units in a container, without the need for a large number of copper pipes. The entire equipment can be deployed quickly and flexibly, and can be used in water-scarce areas in the north. It does not require any water treatment, and the water utilization rate is zero. Indirect heat exchange also avoids outdoor air pollution, achieving low-carbon and efficient operation.

[0004] Since the fluorine pump integrated machine has a large cooling capacity, which can reach more than 300kW (kilowatts), multiple refrigerant systems are required to achieve large cooling capacity heat exchange. At present, conventional products in the industry have three systems and four systems. If one of the refrigerant systems fails during normal operation, it will cause the internal air supply temperature of the unit to overheat, causing the entire machine to need to be shut down for maintenance.

[0005] In view of this, the art urgently needs a method for controlling the supply air temperature, which can maximize the utilization of the cooling capacity of the unit under fault conditions, so that the fluorine pump integrated machine can adjust the cooling capacity as needed and provide stable cooling.

[0067] In order to enable ordinary persons in the art to better understand the technical solutions of the present disclosure, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings.

[0068] It should be noted that the terms "first", "second", etc. in the specification and claims of the present disclosure and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present disclosure described herein can be implemented in an order other than those illustrated or described herein.

[0069] The following example embodiments can be implemented in a variety of forms and should not be construed as being limited to the examples set forth herein; on the contrary, these embodiments are provided so that the present disclosure will be more comprehensive and complete, and the concepts of the example embodiments are fully conveyed to those skilled in the art. The described features, structures, or characteristics may be combined in one or more embodiments in any suitable manner. In the following description, many specific details are provided to provide a full understanding of the embodiments of the present disclosure. However, those skilled in the art will appreciate that the technical solutions of the present disclosure may be practiced while omitting one or more of the specific details, or other methods, components, devices, steps, etc. may be adopted. In other cases, known technical solutions are not shown or described in detail to avoid obscuring various aspects of the present disclosure.

[0070] In addition, the accompanying drawings are only schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the figures represent the same or similar parts, and their repeated description will be omitted. Some of the block diagrams shown in the accompanying drawings are functional entities and do not necessarily correspond to physically or logically independent entities. These functional entities can be implemented in software form, or implemented in one or more hardware modules or integrated circuits, or implemented in different networks and / or processor devices and / or microcontroller devices.

[0071] The main function of the fluorine pump in the entire refrigeration cycle is to effectively transport liquid refrigerant to various components, rather than directly handling gas. In the fluorine pump system, the refrigerant circulates between liquid and gaseous states. The liquid refrigerant is pumped to the evaporator by the fluorine pump, absorbs heat and becomes gaseous. The gaseous refrigerant is compressed by the compressor and then sent to the condenser to cool it into liquid, completing the entire cycle. The application advantages of this technology mainly lie in its high efficiency and flexibility. Compared with traditional water cooling systems, the fluorine pump system can provide stronger cooling capacity at lower energy consumption and is suitable for high-density heat load environments. In addition, the modular design of the fluorine pump system makes it easy to integrate and expand, and the cooling capacity can be flexibly adjusted according to actual needs.

[0072] There are two main types of air-conditioning products derived from fluorine pump technology: split fluorine pump units and integrated fluorine pump units. When the cooling capacity is below 200kW, the split type can be selected, and when the cooling capacity is above 200kW, the integrated type can be selected. When the outdoor temperature is ≤15℃, the fluorine pump of this air-conditioning has a certain cooling effect, thereby reducing the refrigeration of the compressor; when the outdoor temperature is ≤8 degrees, the fluorine pump has a 100% cooling effect, and the compressor refrigeration can be turned off. Therefore, this technology can use the fluorine pump circulation hours throughout the year account for a large proportion, and the energy-saving effect is better.

[0073] Taking the fluorine pump integrated machine with 4 refrigerant systems as an example, under different system operating conditions, the internal operation of the fluorine pump integrated machine system is as follows:

[0074] Figure 1 A schematic diagram of the interior of a fluorine pump integrated system in normal operation in a related embodiment of the present disclosure is shown. The cooling capacity of the whole machine is N, and each system is responsible for 1 / 4 of the cooling capacity. The 36°C hot air in the return air zone is cooled to 22°C through 4 systems and sent out of the unit into the machine room through the blower.

[0075] Figure 2 A schematic diagram of the interior of a fluorine pump integrated system after a refrigerant system failure in another related embodiment of the present disclosure is shown. After the failure of system 1, part of the return air directly flows into the supply air area through system 1 without cooling, and the supply air temperature will rise and be higher than 22°C.

[0076] Figure 3 A schematic diagram of the interior of the fluorine pump integrated system after failure of two refrigerant systems in another related embodiment of the present disclosure is shown. After the failure of systems 1 and 2, a large amount of return air directly flows into the supply air area through systems 1 and 2 without cooling. The supply air temperature rises even higher and can no longer be delivered to the machine room, so it needs to be shut down.

[0077] The advantage of the fluorine pump integrated machine is that it provides large-scale cooling capacity, but due to the failure of one or two refrigerant systems inside the unit, the unit's air supply temperature will be high, requiring on-site personnel to perform emergency shutdown maintenance, which overall reduces the cooling redundancy and reliability of the computer room operation. If a single subsystem of multiple devices fails, it will directly bring about the risk of high temperature operation in the computer room.

[0078] The main reason for overheating caused by a single or multiple system failure inside the unit is that the evaporator corresponding to the faulty refrigerant system stops cooling, causing hot air to flow through, and the fan speed is high, making the mixed air more serious. Therefore, it is necessary to avoid the problem of hot air flow caused by a single or multiple system failure inside the fluorine pump integrated unit.

[0079] Based on the above problems, this exemplary embodiment first provides a method for controlling the supply air temperature. Figure 4 As shown, the above-mentioned method for controlling the supply air temperature may include the following steps:

[0080] Step S410. An electric shutter is provided at the hot air inlet of the refrigerant system inside the fluorine pump integrated machine, and a temperature sensor is provided at the cold air outlet after refrigeration of the refrigerant system.

[0081] Step S420: When a refrigerant system fails, the electric shutters corresponding to the failed refrigerant system are set to close according to the temperature value obtained by the temperature sensor corresponding to the failed refrigerant system.

[0082] Step S430. According to the number of faulty refrigerant systems and the cooling capacity of the fluorine pump integrated machine, the speed of the blower in the fluorine pump integrated machine is limited to control the air supply temperature of the fluorine pump integrated machine.

[0083] In the method for controlling the air supply temperature of the example embodiment of the present disclosure, electric shutters are set at the hot air inlet of the refrigerant system inside the fluorine pump integrated machine, and a temperature sensor is set at the cold air outlet after refrigeration of the refrigerant system. When the refrigerant system fails, the electric shutters corresponding to the faulty refrigerant system are set to close according to the temperature value obtained by the temperature sensor corresponding to the faulty refrigerant system, and then the speed of the air supply fan in the fluorine pump integrated machine is limited to control the air supply temperature of the fluorine pump integrated machine. The control method of the air supply temperature in the example implementation mode of the present disclosure increases electric shutters and temperature sensors inside the fluorine pump integrated machine, controls the linkage between the temperature sensor and the electric shutter, and solves the problem of high temperature of the unit air supply caused by the failure of the refrigerant system inside the fluorine pump integrated machine through cold and heat isolation and the addition of a control system, thereby maximizing the utilization of the unit's cooling capacity under the fault state without affecting the unit's air supply, thereby ensuring that the air inlet temperature of the server in the computer room is stable and does not shut down; when a system failure occurs, the fluorine pump integrated machine can adjust the cooling capacity as needed to provide stable cooling, thereby extending the cooling time of the unit and the maintenance time of on-site operation and maintenance, and can also increase the cooling redundancy coefficient of the computer room after multiple failures of the refrigerant system.

[0084] Next, combine Figures 5 to 7 The above steps of this exemplary embodiment are described in more detail.

[0085] In step S410, an electric shutter is provided at the hot air inlet of the refrigerant system inside the fluorine pump integrated machine, and a temperature sensor is provided at the cold air outlet after refrigeration of the refrigerant system.

[0086] In this example implementation, a set of electric shutters can be set at the hot air inlet of each refrigerant system inside the fluorine pump integrated machine, and a temperature sensor can be added at the cold air outlet position of each refrigerant system after refrigeration. By detecting the working status of the corresponding refrigerant system and the refrigerant system outlet temperature sensor, the linkage start and stop can be performed.

[0087] In step S420, when a refrigerant system fails, the electric shutters corresponding to the failed refrigerant system are set to close according to the temperature value obtained by the temperature sensor corresponding to the failed refrigerant system.

[0088] When one or more refrigerant systems inside the fluorine pump integrated machine fail, the faulty refrigerant system will shut down. After the faulty refrigerant system is shut down, the electric shutters corresponding to the faulty refrigerant system can be controlled to close according to the temperature value obtained by the temperature sensor corresponding to the faulty refrigerant system.

[0089] In this example implementation, the fault temperature threshold can be determined according to the air supply temperature setting value of the fluorine pump integrated machine. When the temperature value obtained by the temperature sensor corresponding to the faulty refrigerant system reaches the fault temperature threshold, the electric shutter corresponding to the faulty refrigerant system is set to be closed.

[0090] When a refrigerant system generates an alarm that causes the compressor or fluorine pump to stop refrigeration, the system will shut down. After the shutdown, if the temperature value obtained by the temperature sensor is greater than the fault temperature threshold, such as the air supply temperature setting value T+3℃ of the fluorine pump integrated machine, a signal is sent to close the corresponding electric shutter.

[0091] In step S430, according to the number of faulty refrigerant systems and the cooling capacity of the integrated fluorine pump machine, the speed of the blower in the integrated fluorine pump machine is limited to control the air supply temperature of the integrated fluorine pump machine.

[0092] Taking the fluorine pump integrated machine with 4 refrigerant systems as an example, after one refrigerant system is shut down, the cooling capacity of the whole system is reduced by 1 / 4. In order to ensure that the cooling capacity of the existing unit matches the fan speed, it is necessary to give the limited speed of the blower through logical calculation to avoid insufficient cooling of the unit due to excessively high operating frequency of the blower.

[0093] In this example implementation, Figure 5 As shown, according to the number of faulty refrigerant systems and the cooling capacity of the fluorine pump integrated machine, the speed of the blower in the fluorine pump integrated machine is limited, which may include the following steps:

[0094] Step S510: Determine the actual cooling capacity of the fluorine pump integrated machine before the refrigerant system fails.

[0095] In this example implementation, the temperature difference can be obtained based on the supply air temperature and return air temperature of the fluorine pump integrated machine before the refrigerant system fails, and then the actual cooling capacity of the fluorine pump integrated machine before the refrigerant system fails can be determined based on the set air volume and air specific heat of the fluorine pump integrated machine, as well as the blower speed and temperature difference of the fluorine pump integrated machine before the refrigerant system fails. Among them, the air specific heat can be determined based on the supply air temperature setting value of the fluorine pump integrated machine.

[0096] Before the refrigerant system fails, the calculation formula for the actual cooling capacity Q (operation) of the fluorine pump integrated machine is as follows:

[0097] Q(operation) = M*F0*1.01*(Th(operation)-Ts(operation))——kW

[0098] Among them, M is the set air volume of the original fluorine pump integrated machine, in kg / s; the supply air temperature and return air temperature of the fluorine pump integrated machine before the refrigerant system fails are Ts (operation) and Th (operation), respectively, and the difference between the two is the temperature difference; the supply air fan speed before the failure is F0; when the supply air temperature setting value is 22°C, the specific heat capacity of air is 1.01.

[0099] Step S520. According to the number of faulty refrigerant systems and the set cooling capacity and actual cooling capacity of the fluorine pump integrated machine, the speed of the blower in the fluorine pump integrated machine is limited.

[0100] In this example implementation, Figure 6 As shown, according to the number of faulty refrigerant systems, as well as the set cooling capacity and actual cooling capacity of the fluorine pump integrated machine, the speed of the blower in the fluorine pump integrated machine is limited, which may include the following steps:

[0101] Step S610. Obtain the target cooling capacity of the fluorine pump integrated machine according to the set cooling capacity of the fluorine pump integrated machine, the number of faulty refrigerant systems and the total number of refrigerant systems.

[0102] After some refrigerant systems fail, the target cooling capacity of the fluorine pump integrated machine is calculated as follows: (Q(set) / X0)*(X0-X), where Q(set) is the set cooling capacity of the fluorine pump integrated machine in kW, the number of failed refrigerant systems is X, and the total number of refrigerant systems is X0.

[0103] Step S620. If the actual cooling capacity of the fluorine pump integrated machine is less than or equal to the target cooling capacity, the speed of the blower in the fluorine pump integrated machine is maintained.

[0104] When judging the cooling capacity, if Q(operation)≤(Q(setting) / X0)*(X0-X), the fan frequency Fx can maintain operation automatically after a system failure.

[0105] Step S630. If the actual cooling capacity of the fluorine pump integrated machine is greater than the target cooling capacity, the speed of the blower in the fluorine pump integrated machine is limited according to the target cooling capacity and the actual cooling capacity of the fluorine pump integrated machine.

[0106] In this example implementation, the cooling capacity change ratio can be obtained based on the target cooling capacity and actual cooling capacity of the fluorine pump integrated machine, and then the limited blower speed can be obtained based on the cooling capacity change ratio and the blower speed before the failure.

[0107] If Q(running)>(Q(setting) / X0)*(X0-X), the fan frequency needs to be limited after the system fails, and the fan frequency limit speed is calculated as follows:

[0108] Fx=(Q(running) / ((Q(setting) / X0)*(X0-X)))*F0

[0109] like Figure 7 The figure shows a schematic diagram of air supply temperature control inside a fluorine pump integrated machine system after a refrigerant system failure in a specific embodiment of the present disclosure. Inside the fluorine pump integrated machine system, refrigerant system 1, refrigerant system 2, refrigerant system 3, and refrigerant system 4 are respectively provided with electric shutters M1, M2, M3, and M4, and temperature sensors T1, T2, T3, and T4.

[0110] After the fluorine pump integrated unit is improved and optimized through the above technical solutions, it can avoid the problem of high temperature of the unit's air supply caused by the failure of the internal refrigerant system of the unit, and ensure that the air inlet temperature of the server in the computer room is stable and does not shut down.

[0111] For example, in actual operation, when a 300kW fluorine pump integrated system fails, the cooling capacity of the unit is as follows:

[0112] When system 1 fails, the unit can operate stably at 225kW cooling without shutting down through this solution.

[0113] When systems 1 and 2 fail, the unit can operate stably at 150kW cooling without shutting down through this solution.

[0114] When systems 1, 2, and 3 fail, the unit can operate stably at 75kW cooling without shutting down through this solution.

[0115] Taking a standard computer room with a cooling load of 8000kW as an example, it is equipped with 28 (main) + 4 (spare) 300kW fluorine pump integrated machines, and the redundancy factor is set to 32*300 / 8000-1=20%.

[0116] When system 1 failure occurs in 4 spare units at the same time, the non-optimized unit shuts down and the redundancy coefficient of the computer room becomes 0. Using the given optimization technical solution, the redundancy coefficient of the unit is (28*300+4*300*3 / 4)-1=16%.

[0117] When system 1 and 2 failures occur simultaneously in the four spare units, the non-optimized units shut down and the redundancy coefficient of the computer room becomes 0. Using the given optimization technical solution, the redundancy coefficient of the units is (28*300+4*300*2 / 4)-1=12%.

[0118] It can be seen that when a system failure occurs, the unit can adjust the cooling capacity as needed to provide stable cooling, thereby extending the unit's cooling time and on-site maintenance time, as well as increasing the room's cooling capacity redundancy factor by more than 10% after multiple unit failures.

[0119] It should be noted that although the steps of the method in the present disclosure are described in a specific order in the drawings, this does not require or imply that the steps must be performed in this specific order, or that all the steps shown must be performed to achieve the desired results. Additionally or alternatively, some steps may be omitted, multiple steps may be combined into one step, and / or one step may be decomposed into multiple steps, etc.

[0120] Furthermore, the present disclosure also provides a control device for supply air temperature. Figure 8 As shown, the air supply temperature control device may include a refrigerant system setting module 810, a refrigerant system closing module 820, and an air supply temperature control module 830. Among them:

[0121] The refrigerant system setting module 810 is configured to set electric shutters at the hot air inlet of the refrigerant system inside the fluorine pump integrated machine, and set a temperature sensor at the cold air outlet after refrigeration of the refrigerant system;

[0122] The refrigerant system closing module 820 is configured to execute, when a refrigerant system fails, setting and closing the electric shutter corresponding to the failed refrigerant system according to the temperature value obtained by the temperature sensor corresponding to the failed refrigerant system;

[0123] The air supply temperature control module 830 is configured to limit the speed of the air supply fan in the fluorine pump integrated machine according to the number of faulty refrigerant systems and the cooling capacity of the fluorine pump integrated machine to control the air supply temperature of the fluorine pump integrated machine.
