[0002] Data centers require a constant temperature and humidity environment, with server inlet air temperatures maintained between 18°C ​​and 27°C. Traditional air handling units (AHUs) require supplemental heat during low winter temperatures. Excess heat in the data center is often transported to the AHU via return air ducts and valves for supplemental heat before being delivered to the data center. However, this approach has several drawbacks, including inadequate utilization of return air heat, resulting in losses and waste during the return air flow. Return air valves can easily affect air volume control logic, leading to unstable supply air volumes. Furthermore, return air ducts occupy significant space, compressing the AHU's actual air supply space. Utility Model Content

[0043] As shown in Figure 1 The air handling system provided by the embodiment of the present application comprises a heat exchange device 100, a heat storage device 200 and an air handling device 300, the heat exchange device 100 is arranged in a machine room 400, the heat storage device 200 is in communication with the heat exchange device 100, the air handling device 300 is in communication with an air inlet of the machine room 400, and the air handling device 300 and the heat storage device 200 are adapted to switch between a communication mode and a disconnected mode, in the disconnected mode, the air handling device 300 cools the fresh air entering the machine room 400, and in the communication mode, the air handling device 300 cooperates with the heat storage device 200 to heat the fresh air entering the machine room 400.

[0044] The air handling system of the embodiment of the present application mainly comprises a heat exchange device 100, a heat storage device 200 and an air handling device 300, the heat exchange device 100 is arranged inside a machine room 400 of a data center, the heat storage device 200 is in communication with the heat exchange device 100, the air inside the machine room 400 is heated, and the air exchanges heat with the heat exchange device 100 before being discharged from the machine room 400, the heat exchange device 100 absorbs the heat in the air and stores the heat in the heat storage device 200, the air handling device 300 is arranged outside the machine room 400, and the air outlet of the air handling device 300 is in communication with the air inlet of the machine room 400, that is, the fresh air enters the inside of the machine room 400 after being processed by the air handling device 300, and the air handling device 300 can form different modes in different on-off states with the heat storage device 200 to adjust the temperature of the air entering the machine room 400.

[0045] When the air handling device 300 and the heat storage device 200 are in the communication mode, the fresh air enters the air handling device 300, the air handling device 300 heats the fresh air by using the heat stored in the heat storage device 200, and then sends the fresh air into the machine room 400. The communication mode is applied to the low-temperature working condition in winter, the fresh air enters the air handling device 300, the heat storage device 200 transfers the heat stored in the machine room 400 to the fresh air to preheat the fresh air, thereby achieving the effect of heating in winter.

[0046] When the air handling unit 300 and the heat storage device 200 are in disconnected mode, fresh air enters the air handling unit 300, which directly cools the fresh air before delivering it to the computer room 400. This disconnected mode is used in high-temperature summer conditions. When fresh air enters the air handling unit 300, the air handling unit 300 and the heat storage device 200 are disconnected and independent of each other. The air handling unit 300 only cools the fresh air, achieving supplemental cooling in the summer.

[0047] Thus, the coordinated arrangement of heat exchanger 100 and heat storage device 200 enables waste heat recovery from computer room 400. The heat carried by the hot air from computer room 400 can be effectively utilized before it is exhausted, thus avoiding energy waste. Furthermore, combined with the on / off switching of air handling device 300, a cross-seasonal energy storage air handling system can be formed, adapting to the temperature requirements of computer room 400 under different seasonal conditions. This allows for multi-season waste heat utilization, improving energy efficiency and the energy utilization rate of the air handling system, thereby achieving energy savings.

[0048] According to one embodiment of the present invention, the air handling unit 300 includes a refrigeration component 310 and a heat exchange component 320. In a connected mode, the heat exchange component 320 is connected to the heat storage device 200 and disconnected from the refrigeration component 310. In a disconnected mode, the heat exchange component 320 is connected to the refrigeration component 310 and disconnected from the heat storage device 200. In this embodiment, the air handling unit 300 is primarily composed of the refrigeration component 310 and the heat exchange component 320. Both the refrigeration component 310 and the heat exchange component 320 are independently disposed outside the machine room 400. The heat exchange component 320 can be used to perform heat exchange with fresh air entering the air handling unit 300, and the refrigeration component 310 can provide cooling for the heat exchange component 320.

[0049] When the air handling device 300 and the heat storage device 200 are in a connected mode, fresh air enters the air handling device 300, the heat exchange component 320 is connected to the heat storage device 200, and the heat stored in the heat storage device 200 enters the heat exchange component 320. The fresh air absorbs heat through contact with the heat exchange component 320, causing the temperature to rise, and the refrigeration component 310 does not participate in operation. When the air handling device 300 and the heat storage device 200 are in a disconnected mode, fresh air enters the air handling device 300, the heat exchange component 320 is connected to the refrigeration component 310, and the fresh air absorbs cold energy through contact with the heat exchange component 320, causing the temperature to fall, and the heat storage device 200 does not participate in operation.

[0050] According to one embodiment of the present invention, the air handling device 300 further includes an air supply duct 330, which is disposed outside the machine room 400 and adapted to communicate with the air inlet of the machine room 400. The heat exchange component 320 is disposed within the air supply duct 330. In this embodiment, the air handling device 300 primarily comprises the air supply duct 330, the heat exchange component 320, and the refrigeration component 310. The air supply duct 330 communicates with the air inlet of the machine room 400. The heat exchange component 320 is disposed within the air supply duct 330, while the refrigeration component 310 is disposed outside the air supply duct 330.

[0051] The air outlet of the air supply duct 330 is connected to the air inlet of the machine room 400. Fresh air enters the air supply duct 330 through the air inlet and directly exchanges heat with the heat exchange component 320 to achieve heating or cooling. During actual equipment assembly, the configuration of the refrigeration component 310 and the heat exchange component 320 can be used in the existing configuration of the air handling unit 300, requiring only the connection between the heat exchange component 320 and the heat storage device 200 to be added.

[0052] According to one embodiment of the present invention, heat storage device 200 is connected to a domestic hot end and is suitable for supplying heat to the domestic hot end. In this embodiment, heat storage device 200 is connected to the domestic hot end. After heat exchange device 100 stores heat recovered from computer room 400 in heat storage device 200, heat storage device 200 can then deliver the heat to the domestic hot end, providing a heat source for users. This provides another way to use the excess heat in computer room 400.

[0053] After the waste heat of the machine room 400 is recovered by the heat exchange device 100 and the heat storage device 200, the waste heat inside the machine room 400 can be used in other living areas under direct ventilation conditions such as spring and autumn, thereby effectively utilizing the waste heat of the machine room 400 in spring and autumn, avoiding energy waste and further improving the energy utilization rate of the air treatment system with cross-seasonal energy storage.

[0054] According to one embodiment of the present invention, heat storage device 200 includes a water tank, which is connected to heat exchange device 100 and heat exchange component 320 via water pipes, each of which is equipped with a water pump. In this embodiment, heat storage device 200 is primarily composed of the water tank, meaning that the heat exchange medium flowing between heat exchange device 100 and heat storage device 200 is water, and the heat exchange medium flowing between heat storage device 200 and heat exchange component 320 is also water. The water pump provides power to circulate the heat in the water tank through the water pipes to heat exchange device 100 and heat exchange component 320.

[0055] During direct ventilation conditions in spring and autumn, the excess heat within the computer room 400 can be used to heat and store water in the water tank via the heat exchanger 100. During low temperatures in winter, the water in the water tank, which has been heated and stored, enters the heat exchanger 320 to heat the fresh air. Furthermore, the water in the water tank can be connected to a domestic heat source for use in other areas of life, such as heating and hot water systems.

[0056] In other embodiments, the selection of components of the heat storage device 200 is related to actual needs and the selected heat exchange medium.

[0057] According to one embodiment of the present invention, the heat exchange component 320 includes heat exchange pipes, which are respectively connected to the heat storage device 200 and the refrigeration component 310. In this embodiment, the heat exchange component 320 is mainly composed of heat exchange pipes, which are connected to the water tank through water pipes, and the heat exchange pipes are connected to the refrigeration component 310 through pipelines.

[0058] During summer heat, the original air handling unit 300 requires a supplemental cooling section to cool the hot air with cold water. Therefore, the existing piping connecting the heat exchange tubes to the refrigeration unit 310 is reused. The water tank stores water that absorbs excess heat from the machine room 400. During winter colder temperatures, the water in the tank flows into the heat exchange tubes to preheat the fresh air.

[0059] In this embodiment, the heat exchange tube has low cost, convenient layout, easy disassembly and replacement, and reduces construction difficulty. In other embodiments, the heat exchange component 320 can adopt other heat exchangers that can circulate water, or matching heat exchangers that meet the needs of other heat exchange media.

[0060] According to one embodiment of the present invention, a heat exchange device 100 is installed at the top of the machine room 400. In this embodiment, the heat exchange device 100 is installed in the upper space of the machine room 400, and the exhaust vent of the machine room 400 is arranged at the top of the machine room 400. To ensure the full recovery of waste heat from the machine room 400, the heat exchange device 100 is installed at the end of the exhaust path of the machine room 400 to promote the full recovery of waste heat from the heat exchange device 100.

[0061] In other embodiments, the heat exchange device 100 may also be arranged at other locations in the machine room 400 as long as the waste heat can be normally recovered.

[0062] According to one embodiment of the present invention, the air handling device 300 further includes a return air duct, one end of which is connected to the return air outlet of the machine room 400, and the other end of which is connected to the supply air duct 330. In this embodiment, a return air duct is further provided between the machine room 400 and the supply air duct 330, and the return air outlet of the machine room 400 is connected to the supply air duct 330 via the return air duct.

[0063] The air in the computer room 400 is generally discharged directly through the exhaust vent of the computer room 400. Now, a heat exchange device 100 is set in the computer room 400 to recover the waste heat carried by the exhausted air. On this basis, a return air vent can be further set in the computer room 400 to send the air to be discharged back to the supply air duct 330 of the air treatment device 300 through the return air duct. If the heat exchange device 100 fails to fully recover the air heat, the return air entering the supply air duct 330 through the return air duct also has a certain amount of heat. Under low temperature conditions in winter, the return air is heated again by the heat exchange component 320, and the return air heat is reused.

[0064] In other embodiments, the exhaust vent and the return air vent of the machine room 400 may be the same vent, and the heat exchange device 100 may be disposed in front of the vent.

[0065] According to one embodiment of the present invention, the ratio of the supply air area of ​​the supply air duct 330 to the return air area of ​​the return air duct is greater than 2:1. In this embodiment, the provision of the heat exchange device 100 and the heat storage device 200 can, to a certain extent, reduce the proportion of the return air duct in the overall duct structure of the air treatment device 300. Therefore, compared to the original air treatment system, the present invention can eliminate a large number of return air ducts and return air valves.

[0066] Compared to traditional air handling systems, which require return air ducts during construction, this compresses the space occupied by the supply air duct 330 in limited space, resulting in a reduced air supply area for the supply air duct 330. The present invention provides an air handling system with seasonal energy storage. While reducing the number of return air ducts, it can ensure a ratio of the supply air area of ​​the supply air duct 330 to the return air area of ​​the return air duct greater than 2:1. To maximize the air supply area, the return air duct can be completely eliminated, with all air ducts designed to be the supply air duct 330.

[0067] The present invention can increase the air supply space of the air handling system by 30%-40%, increase the air supply volume of the air supply duct 330, and make the air flow organization in the computer room 400 more uniform, thereby reducing the overall PUE of the data center, thereby saving a lot of space, improving space utilization, energy utilization and installation simplicity, reducing the difficulty of installing large-volume return air ducts and air valves, and thus reducing the construction difficulty and the investment cost of duct air valves.

[0068] The embodiment of the present invention further provides a data room 400, including a room 400 and the above air handling system, wherein the room 400 is provided with an air inlet; the heat exchange device 100 is provided in the room 400, and the air handling device 300 is connected to the air inlet.

[0069] In the data center 400 of the present invention, an air handling system is applied to the data center 400. The data center 400 is provided with an air inlet, and the powder delivery duct of the air handling device 300 is connected to the air inlet. When the air handling device 300 and the heat storage device 200 are in a connected mode, fresh air enters the air handling device 300. The air handling device 300 uses the heat stored in the heat storage device 200 to heat the fresh air before delivering it to the data center 400. This connected mode is applicable to low-temperature winter conditions. When fresh air enters the air handling device 300, the heat storage device 200 transfers the stored heat from the data center 400 to the fresh air, preheating it and thus achieving a winter heat supplement effect.

[0070] When the air handling unit 300 and the heat storage device 200 are in disconnected mode, fresh air enters the air handling unit 300, which directly cools the fresh air before delivering it to the computer room 400. This disconnected mode is used in high-temperature summer conditions. When fresh air enters the air handling unit 300, the air handling unit 300 and the heat storage device 200 are disconnected and independent of each other. The air handling unit 300 only cools the fresh air, achieving supplemental cooling in the summer.

[0071] Finally, it should be noted that the above embodiments are intended only to illustrate the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art will appreciate that various combinations, modifications, or equivalent substitutions of the technical solutions of the present invention do not depart from the spirit and scope of the present invention and are intended to be encompassed by the claims of the present invention.
