[0002] With the progress of new infrastructure construction such as 5G network and data center, and the new requirements for energy consumption of new infrastructure construction in various places, it is difficult to meet the energy consumption requirements if mechanical refrigeration is adopted in related technologies. Therefore, data centers of financial institutions need to adopt reasonable ways to reduce cooling energy consumption of data centers according to their own conditions.

[0003] For some data center machine rooms built earlier, precision air conditioners with air cooling and direct expansion are mostly used for refrigeration of the machine room. However, in the machine room, cold air will directly return to the air conditioner inlet from the air conditioner outlet without passing through equipment (for example, servers), or leak from the gaps or cable openings on the side and top of the cabinet, resulting in low utilization rate of cold air. The equipment in the machine room may also be locally overheated, which shortens the service life of the equipment. In addition, in order to cool the equipment in the machine room, the air conditioner needs to work for a long time, which results in long working time of the air conditioner compressor, high energy consumption and low refrigeration efficiency of the air conditioner.

[0011] Further, the air flow organization system further comprises: a static pressure bin arranged between a floor of the data center room and a ground of the data center room and configured to receive the cold air generated by the room precision air conditioner and discharge the cold air into the closed passage; and a cold wall made of fireproof composite material and arranged below the closed passage in the static pressure bin and configured to reduce the space of the static pressure bin.

[0033] It should be noted that the aforementioned one or more processors 102 and / or other data processing circuits are generally referred to herein as "data processing circuits". These data processing circuits may be embodied, in whole or in part, in software, hardware, firmware, or any other combination thereof.

[0037] Under the aforementioned operating environment, this application provides the following: Figure 2 The airflow organization method for the data center server room is shown. Figure 2 This is a flowchart of an airflow organization method for a data center computer room according to Embodiment 1 of this application.

[0038] Step S201: Cold air is generated by the precision air conditioner in the computer room to cool down the equipment in the data center computer room.

[0039] The equipment in a data center server room may include servers. In this embodiment, the server room precision air conditioner can receive hot air exhausted from the equipment in the data center server room and convert it into cold air that can cool the equipment in the data center server room.

[0040] Step S202: Cold air is introduced into the equipment in the data center server room through a closed channel to obtain hot air discharged from the equipment, wherein the temperature of the hot air is higher than that of the cold air.

[0041] The aforementioned enclosed channels can be divided into cold enclosed channels and hot enclosed channels. In this embodiment, cold air can be discharged into the cold enclosed channel, and after passing through the equipment in the data center server room, hot air is obtained from the equipment. This hot air can then be discharged into the hot enclosed channel. The aforementioned cold air can be the air discharged from the server room precision air conditioner that has not cooled the equipment, while the hot air can be the air obtained after cooling the equipment.

[0042] In this embodiment, the closed channel can prevent cold air from flowing back directly to the precision air conditioner in the computer room without passing through the equipment, thus avoiding the waste of cold air resources and improving the utilization rate of cold air.

[0043] Step S203: Hot air is discharged into the precision air conditioner in the computer room through the return air duct.

[0044] In this embodiment, the hot air discharged from the equipment can be discharged into the precision air conditioner in the computer room through the return air duct. The precision air conditioner in the computer room can be equipped with a return air cap and tightly connected to the return air inlet of the precision air conditioner. The other end of the air conditioner return air cap is connected to the return air duct, so that the hot air can be directly introduced into the precision air conditioner in the computer room, which improves the utilization rate of cold air and can also avoid the situation that the air conditioner compressor works for a long time, resulting in long working time, high energy consumption and low air conditioning cooling efficiency.

[0045] Through the above steps, in this embodiment, cold air is allowed to flow through the equipment in the data center computer room via a closed channel, and hot air is allowed to flow back to the precision air conditioner in the computer room via a return air channel and a return air cap. This avoids the situation of low cold air utilization in the data center computer room, thereby achieving the technical effect of improving the cold air utilization rate of the data center computer room and solving the technical problem of low cold air utilization rate in the data center computer room.

[0046] Optionally, in the airflow organization method for a data center server room provided in this application embodiment, after generating air capable of cooling the equipment in the data center server room and obtaining cold air, the method further includes: acquiring the pressure difference in the data center server room and obtaining pressure difference data, wherein the pressure difference data includes at least one of the following: the pressure difference in the enclosed channel, the pressure difference between the upper and lower floors in the data center server room; acquiring temperature and humidity data in the data center server room; obtaining a target pressure difference value based on the pressure difference data and the temperature and humidity data through a target model, wherein the target model is used to evaluate the pressure difference value of the data center server room during a target time period; and determining the opening and closing degree of the air inlet in the enclosed channel and the opening and closing degree of the return air outlet in the return air channel based on the target pressure difference value.

[0047] The aforementioned differential pressure data may include the differential pressure within a closed channel, such as the differential pressure between a cold closed channel and a hot closed channel within the closed channel, or the differential pressure between the upper and lower floors of the data center server room. In this embodiment, a static pressure chamber may be installed under the floor, and the cold air generated by the precision air conditioner of the server room may be discharged into the closed channel through the static pressure chamber. In this embodiment, temperature and humidity data in the data center server room may also be collected by installing temperature and humidity sensors in the return air duct, closed channel, static pressure chamber, etc.

[0048] The aforementioned target model can be used to evaluate the pressure difference value (i.e., the pressure difference value within a closed passage, or the pressure difference value between the upper and lower floors of a data center server room) during a target time period. The target model can be a Long Short-Term Memory (LSTM) model. In this embodiment, the target model can be trained based on training samples composed of historical pressure differences, corresponding air vent control quantities (air vent opening, air conditioner fan speed), historical temperature and humidity data, interference factors (e.g., equipment load power, return air temperature, and air conditioner set temperature), and pressure differences at relevant times, so that the target model can predict the pressure difference value at a specified time.

[0049] In this embodiment, the interference factor at the current moment can also be obtained. The interference factor, air outlet control quantity, temperature and humidity data, pressure difference data, and time characteristics (e.g., weekday / holiday, time period) are input into the target model to predict the pressure difference value of the target time period and obtain the target pressure difference value. The target time period can be a time period after the current moment. By predicting the pressure difference value of the target time period, it is convenient to set the opening and closing degree of the return air vent and the cold aisle inlet in advance.

[0050] In one optional example, the pressure difference in the closed aisle (e.g., cold closed aisle pressure - hot closed aisle pressure) needs to be maintained within a first preset pressure difference range (e.g., +5Pa to +20Pa) to ensure that cold air can overcome the resistance of the cabinet containing the equipment (e.g., servers), allowing cold air to flow smoothly through the equipment from the cold closed aisle and preventing hot air backflow. The pressure difference between the floor and the ceiling (e.g., floor static pressure chamber pressure - cold closed aisle pressure) needs to be maintained within a second preset pressure difference range (e.g., +10Pa to +30Pa) to facilitate driving cold air from under the floor through the air vents into the cold aisle. If the pressure difference exceeds the first preset pressure difference range or the second preset pressure difference range, the air inlet can be reduced in size and the return air outlet can be increased in size. In this embodiment, by adjusting the air vent opening in advance, the situation of adjustment lag can be avoided.

[0051] In this embodiment, the air vent opening can be increased in advance based on the predicted surge in equipment load, thus avoiding overheating of the equipment due to a sudden drop in pressure differential.

[0052] 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, and although a logical order is shown in the flowchart, in some cases the steps shown or described may be executed in a different order than that shown here.

[0053] Example 2

[0054] Embodiment 2 of the present invention provides an optional airflow organization system for a data center computer room, which can be used to execute the airflow organization method for a data center computer room provided in Embodiment 1.

[0055] Figure 3 This is a schematic diagram of an airflow organization system for a data center computer room according to an embodiment of this application, such as... Figure 3 As shown, it includes: a precision air conditioner for the computer room, a closed passageway, a return air passageway, and a return air hood.

[0056] The system includes a precision air conditioner for the data center, which generates cool air to cool the equipment in the data center; a closed duct, which allows cool air to flow through the equipment in the data center to become hot air, and then exhausts the hot air through the outlet; the equipment in the data center generates heat during operation, and the temperature of the hot air is higher than that of the cool air; a return air duct, located at the top of the data center, allows the hot air exhausted from the outlet of the closed duct to enter; and a return air cap, which connects to both the return air duct and the precision air conditioner for the data center, allows the hot air in the return air duct to enter and exhausts the hot air into the precision air conditioner.

[0057] In this embodiment, the precision air conditioner for the computer room can receive hot air discharged from the return air duct and generate cold air to cool the equipment in the data center computer room. The cold air discharged by the precision air conditioner can be discharged into the closed duct through the air inlet of the closed duct, and after passing through the equipment, it is discharged as hot air. The hot air can be discharged into the return air passage through the return air duct, and then discharged into the precision air conditioner for the computer room through the return air passage. This avoids the situation in related technologies where cold air does not flow into the equipment, resulting in low cold air utilization, thereby achieving the technical effect of improving cold air utilization.

[0058] In this embodiment, a closed channel is used to allow cold air to flow through the equipment in the data center server room, and the hot air is returned to the precision air conditioner in the server room via a return air duct and return air cap. This avoids the low utilization rate of cold air in the data center server room, thereby achieving the technical effect of improving the cold air utilization rate of the data center server room. This solves the technical problem of low cold air utilization rate in data center server rooms.

[0059] Optionally, the airflow organization system for the data center computer room provided in this application embodiment further includes: N temperature and humidity sensors for collecting temperature and humidity data at N locations in the data center computer room, wherein the N locations include at least one of the following: return air duct, enclosed duct, and N is a positive integer; a differential pressure detection device for detecting the differential pressure in the data center computer room and obtaining differential pressure data, wherein the differential pressure data includes at least one of the following: the differential pressure between cold air and hot air in the enclosed duct, and the differential pressure between the upper and lower floors of the data center computer room; and a central controller for regulating the differential pressure in the data center computer room and simulating the temperature and humidity distribution in the data center computer room based on the temperature and humidity data.

[0060] In this embodiment, the temperature and humidity sensor can be deployed in the return air duct, the cold closed duct and the hot closed duct in the enclosed duct, and it can also be deployed under the floor of the data center computer room. In this embodiment, the temperature and humidity data in the data center computer room can be collected by the temperature and humidity sensor.

[0061] The aforementioned differential pressure data can include the pressure difference between cold and hot air within a closed channel, as well as the pressure difference between the upper and lower floors of the data center server room. This pressure difference can be obtained by collecting pressure data between the cold and hot closed channels within the closed channel and calculating the difference. Alternatively, the pressure difference between the upper and lower floors of the data center server room can be obtained by collecting pressure data within the cold closed channels on the floor and the pressure data within the static pressure chamber beneath the floor, and calculating the difference between these values.

[0062] In this embodiment, differential data and temperature and humidity data can be transmitted to the central controller, and the pressure difference for the target time period can be predicted through the target model deployed in the central controller.

[0063] For example, the current disturbance factors (e.g., equipment load, return air temperature, and air conditioner set temperature) and vent control quantities (e.g., vent opening and air conditioner fan speed) can be obtained. The disturbance factors, vent control quantities, temperature and humidity data, pressure difference data, and time characteristics (e.g., weekday / holiday and time period information) can be input into the target model to predict the pressure difference value for the target time period and obtain the target pressure difference value. The target time period can be a time after the current time. By predicting the pressure difference value for the target time period, it is convenient to set the opening and closing degree of the return air vent and the cold aisle inlet in advance.

[0064] In one optional example, the pressure difference in the closed aisle (e.g., cold closed aisle pressure - hot closed aisle pressure) can be maintained within a first preset pressure difference range (e.g., +5Pa to +20Pa) to ensure that cold air can overcome the resistance of the cabinet where the equipment (e.g., servers) is located, allowing cold air to flow smoothly through the equipment from the cold closed aisle and preventing hot air backflow. The pressure difference between the floor and the ceiling (e.g., floor static pressure chamber pressure - cold closed aisle pressure) can be maintained within a second preset pressure difference range (e.g., +10Pa to +30Pa) to facilitate driving cold air from under the floor through the air vents into the cold aisle. If the pressure difference exceeds the first preset pressure difference range or the second preset pressure difference range, the air inlet can be reduced in size and the return air outlet can be increased in size. In this embodiment, by adjusting the air vent opening in advance to regulate the pressure difference in the data center server room, the situation of adjustment lag can be avoided.

[0065] In this embodiment, the temperature and humidity distribution can also be simulated by a central controller based on temperature and humidity data, so as to continuously adjust the location of ventilation floor openings, air conditioning operating parameters, IT equipment layout, etc., to achieve dynamic optimization of the cold air in the computer room.

[0066] Optionally, in the airflow organization system of the data center server room provided in this application embodiment, the enclosed channel includes: a cold enclosed channel, disposed between face-to-face equipment racks, for introducing cold air and discharging cold air into the face-to-face equipment racks, wherein the front panels of the two face-to-face equipment racks are arranged facing each other, and the equipment racks contain equipment for the data center server room; and a heat enclosed channel, disposed between back-to-back equipment racks, for receiving hot air discharged from the back-to-back equipment racks, wherein the rear panels of the two back-to-back equipment racks are arranged facing each other.

[0067] The equipment in a data center can be servers, and the equipment racks can be racks that house servers.

[0068] Figure 4 This is a schematic diagram of another optional airflow organization system for a data center computer room according to an embodiment of this application, such as... Figure 4 As shown, enclosed channels can include cold enclosed channels and hot enclosed channels.

[0069] In this embodiment, within the data center server room, server racks can be placed face-to-face at a distance of no less than a first preset distance (e.g., 1.2m), forming a cold-sealed aisle with the server air inlets facing each other. Cold air is drawn into the equipment through this cold-sealed aisle. Transparent glass doors can be installed above and at both ends of the cold-sealed aisle to completely seal it and prevent cold air from mixing with hot air. The cold aisle is equipped with air inlets that can automatically adjust their opening and closing degree, thereby regulating airflow and air speed.

[0070] In this embodiment, within the data center server room, server racks can be placed back-to-back at a distance of no less than a second preset distance (e.g., 1m), creating a thermally sealed channel between the server exhaust vents. The hot air exhausted from the equipment collects within this thermally sealed channel. An adjustable return air vent can be installed in the ceiling above the thermally sealed channel to completely guide the hot air into the return air channel.

[0071] By setting up cold and hot sealed channels, cold air can be prevented from being directly drawn back into the precision air conditioning unit in the computer room without passing through the equipment, thereby improving the utilization rate of cold air.

[0072] Optionally, in the airflow organization system of the data center computer room provided in this application embodiment, the cold sealed channel is provided with an air inlet that can adjust the degree of opening and closing. The air inlet is used to introduce cold air into the cold sealed channel, and the air volume and speed of the cold air discharged into the cold sealed channel can be adjusted by adjusting the size of the air inlet. The hot sealed channel is provided with an exhaust port, which is used to discharge hot air from the hot sealed channel into the return air channel.

[0073] like Figure 4 As shown, in this embodiment, the cold-sealed aisle is equipped with an air inlet that can automatically adjust its opening and closing degree, which serves to regulate the air volume and speed. The hot-sealed aisle can be equipped with an exhaust vent to discharge the hot air from the hot-sealed aisle and allow the hot air to be discharged into the return air aisle. Adding an air inlet with an automatically adjustable opening and closing degree to the floor of the cold-sealed aisle ensures that cold air can be accurately and powerfully delivered to the return air vent of the IT equipment, and that hot air can flow back smoothly.

[0074] Optionally, in the airflow organization system of the data center computer room provided in this application embodiment, the return air duct includes: a first return air inlet, which is located above the exhaust air outlet of the thermally sealed duct and is used to receive hot air; and a second return air inlet, which is connected to the return air cap and is used to discharge the hot air in the return air duct into the precision air conditioner of the computer room through the return air cap.

[0075] like Figure 4 As shown in this embodiment, an air conditioning return air cap is installed between the return air vent of the precision air conditioner in the computer room and the second return air vent of the return air duct. One end of the air conditioning return air cap is tightly connected to the return air vent of the precision air conditioner, and the other end is connected to the second return air vent of the return air duct. The first return air vent of the return air duct is located above the thermally sealed duct, and this first return air vent has an automatic adjustment function for its opening and closing degree. This avoids placing the first return air vent near or at a low position in the cold aisle, and also removes obstructions to ensure that hot air can flow unobstructed to the first return air vent. Sufficient distance or physical separation is ensured between the return air vent and the air outlet of the precision air conditioner in the computer room to prevent cold air from being directly drawn back into the air conditioner without cooling the IT equipment, thus improving the utilization rate of cold air.

[0076] Optionally, in the airflow organization system of the data center computer room provided in this application embodiment, the airflow organization system further includes: a static pressure chamber, which is set between the floor of the data center computer room and the ground of the data center computer room, for receiving the cold air generated by the precision air conditioner of the computer room and exhausting the cold air into the closed channel; and a cold wall, which is made of fireproof composite material and is set below the closed channel in the static pressure chamber, for reducing the space of the static pressure chamber.

[0077] like Figure 4 As shown, in this embodiment, the airflow organization system further includes a static pressure chamber, which is located between the floor of the data center server room and the ground of the data center server room. It is used to receive the cold air generated by the precision air conditioner of the server room and discharge the cold air into the closed channel. The static pressure chamber area directly below the cold closed channel can be constructed with fireproof composite material to reduce the space of the static pressure chamber and concentrate the cold air to be delivered to the IT equipment in the closed channel.

[0078] Optionally, the airflow organization system for the data center computer room provided in this application embodiment further includes: a blind plate for sealing a target location in the data center computer room, wherein the target location includes: the location of the equipment to be installed; and a blocker for sealing a target opening in the data center computer room, wherein the target opening includes: an opening capable of leaking cold air.

[0079] In this embodiment, blind flanges can be used to tightly seal all U-positions where no equipment is installed, preventing cold air from short-circuiting back from the front of the cabinet to the rear. Cable openings, unnecessary floor openings, and gaps in cable trays can also be sealed with plugs to prevent cold air from leaking into unwanted areas or return air zones, thus achieving the technical effect of improving the utilization rate of cold air.

[0080] In this embodiment, a return air duct is created by adding a suspended ceiling to the computer room, and a return air cap is added to the precision air conditioner in the computer room. This optimizes the return air system, allowing cold air to effectively cool the IT equipment. By monitoring the pressure difference between the cold and hot sealed aisles and between the floor and the floor in real time, and by installing adjustable air inlets that act as air guides under the cold aisle, it is ensured that cold air can be accurately and powerfully delivered to the IT equipment for cooling. Temperature and humidity sensors are installed in the return air duct, the cold and hot sealed aisles, and the static pressure chamber. The temperature and humidity sensors transmit the collected information to the central controller. The central controller processes the data input from the temperature and humidity sensors in real time, monitors the temperature and humidity in the computer room, and adjusts the opening and closing degree of the return air inlet of the return air duct and the air inlet of the cold sealed aisle using an LSTM temperature and humidity prediction model. The system simulates the temperature and humidity distribution and achieves dynamic optimization by continuously adjusting the air conditioning operating parameters and the layout of the IT equipment. Fire-resistant composite materials were used to construct a new cold wall in the static pressure chamber area directly below the cold sealed aisle, reducing the static pressure chamber space and concentrating the cold air delivery to the IT equipment to cool it down.
