Description

Technical Field

[0001] The utility model relates to the technical field of data room air conditioners, in particular to an energy-saving recycling device for data room air conditioners. Background Art

[0002] The data room is an important facility for managing and processing large amounts of data information. It has many servers inside. Since the data room needs to perform large amounts of data calculation and processing 24 hours a day, it will generate a lot of heat. A precision air-conditioning system is required inside the data room to control the temperature and humidity of the room to ensure the stable operation of the servers.

[0003] Existing precision air conditioners in data rooms usually use return air ducts and outlet air ducts to achieve circulating cooling of the air inside the room. That is, the return air duct absorbs the air inside the room, and after being re-cooled by the precision air conditioning system, it is discharged back into the room through the outlet air duct, thereby realizing the recycling of air. Although this method greatly saves energy output, it does not achieve on-demand cooling inside the room. That is, the cooling capacity is the same in places where more heat is generated and places where less heat is generated. Compared with places where less heat is generated, the cooling capacity is wasted more. Based on the above situation, it is necessary to design an energy-saving recycling device for data room air conditioners to solve the above problems. Utility Model Content

[0004] The utility model provides an energy-saving recycling device for air conditioning in a data room. The device divides the interior of the room into independent heat-generating areas and provides cooling on demand according to the heat-generating conditions of the heat-generating areas, thereby achieving economical utilization of cooling capacity and further improving the energy-saving effect of the existing energy-saving recycling device for air conditioning in a data room.

[0005] The technical problem solved by the present invention is achieved by the following technical solutions:

[0006] A data room air conditioning energy-saving recycling device includes an air conditioning unit, an input end of the air conditioning unit is provided with a return air duct, an output end of the air conditioning unit is provided with an air outlet duct, a controller and multiple independent heat generation areas, the air outlet duct is correspondingly provided with air outlets facing the heat generation areas, the position of the air outlet is provided with an electric valve for controlling the opening and closing of the air outlet, and the electric valve is controlled by the controller.

[0007] Preferably, the heat generating area is defined by the heat dissipation surface of the cabinet and the enclosure inside the computer room, and the heat generating area has an exhaust vent.

[0008] Preferably, each of the heat-generating areas is internally provided with a temperature sensor, and the output end of the temperature sensor is connected to the input end of the controller to provide the controller with a temperature signal of the heat-generating area. The output end of the controller sends a control signal, and the control signal is used to control the corresponding electric valve to operate.

[0009] Preferably, a mounting cylinder is provided at the air outlet position, a connecting hole is opened on the side wall of the mounting cylinder, and the electric valve includes a permanent magnet fixing ring, a guide rod, an electromagnet sliding ring and a spring. When the controller controls the electromagnet sliding ring to be energized, the electromagnet sliding ring generates magnetism and is adsorbed by the permanent magnet fixing ring, and slides along the guide rod toward the permanent magnet fixing ring. The spring is compressed and the connecting hole is in an open state. When the electromagnet sliding ring is powered off, the spring resets and drives the permanent magnet fixing ring to move to a state of blocking the connecting hole.

[0010] Preferably, a hair dryer is further provided inside the mounting barrel, and the hair dryer is operated under the control of a controller.

[0011] Preferably, the return air duct is located at a high position, and the outlet air duct is located at a low position.

[0012] The beneficial effect of the present invention is that it achieves energy saving by arranging a plurality of mutually independent heat-generating areas inside the machine room and by supplying cooling to the independent heat-generating areas on demand.

DETAILED DESCRIPTION

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0025] refer to Figures 1-4 The utility model mainly provides an energy-saving recycling device for air conditioning in a data computer room, which includes an air conditioning unit 1, which is used to convert high-temperature air into low-temperature air. A return air duct 2 is provided at the input end of the air conditioning unit 1 to recover indoor hot air (lower than the external air temperature of the computer room). An air outlet duct 3 is provided at the output end of the air conditioning unit 1 to discharge the cooled air. In this way, the temperature of the data computer room is controlled by circulating the air inside the data computer room for cooling. Moreover, since the return air inside the data computer room is utilized in the cooling process, energy saving effect is achieved.

[0026] The problem with existing data room air conditioners is that when they cool the interior of the data room, due to the large space inside the data room and the different power levels of the server cabinets 4 inside the room, the heat generated is also different. Therefore, the existing data room can only provide cooling at the same time, resulting in a mismatch between the supply and demand of cooling capacity, thereby causing waste.

[0027] The main innovation of the present invention is that multiple heat generating areas 18 are set up inside the machine room, and multiple air outlets 9 are set up on the existing air outlet pipe 3 to supply cooling to the heat generating areas 18, thereby realizing on-demand distribution of cooling capacity and achieving precise regulation of cooling capacity use.

[0028] Specifically, refer to Figure 6 , is a way to realize the heat-generating area 18, which is defined by two cabinets 4 and an enclosure 6, with the operating side of the cabinet 4 facing outward. The heat-dissipating side of the cabinet 4 faces the enclosure 6, and the heat-dissipating sides of the two cabinets 4 form the side walls of the heat-generating area 18, which together with the inverted U-shaped plate form a downward-opening heat-generating area 18. The downward opening of the heat-generating area 18 is located on the air outlet 3, and is connected to the interior of the air outlet 3 through the air outlet 9. It should be noted that the heat-generating area 18 can also be formed by the enclosure 6 alone. For example, a five-sided enclosure 6 is used to form a downward-opening heat-generating area 18, and the cabinet 4 is placed inside the heat-generating area 18. By supplying cold air to the heat-generating area 18, the internal cabinet 4 can be fully cooled. Figure 6 In the embodiment, the heat generating area 18 formed by the two cabinets 4 and the U-shaped plate is formed, and the temperature is controlled by cooling the heat dissipation surface 401 of the cabinet 4. Preferably, the heat dissipation surface 401 of the cabinet 4 is cooled. Figure 6 The operation surface 402 of the cabinet 4 is placed outside the heat generating area 18, which is convenient for operation. Of course, there are many ways to construct the heat generating area 18. The main method is to make the heat generating parts of the cabinet 4 or multiple cabinets 4 independent. They will not be elaborated here. An exhaust port 7 is also provided on the upper part of the heat generating area 18 for communicating with the space of the data room to achieve hot air discharge, that is, the cooling process. Figure 4 As shown by the arrow A1, the air conditioning unit 1 first refrigerates the air and discharges it into the air outlet duct 3. The air then enters the heat generating area 18 through the air outlet 9. The hot air inside the heat generating area 18 enters the data room through the air outlet 7. After accumulating at the top of the data room, the hot air is recovered from the return air duct 2 and flows back into the air conditioning unit 1. The air conditioning unit 1 recools the recovered air and flows it back into the air outlet duct 3 again.

[0029] Furthermore, an electric valve is provided at the position of the air outlet 9 for controlling the on and off of the air outlet 9, that is, controlling whether the air outlet pipe 3 is connected to the interior of the heat generating area 18. When the two are in a connected state, the air outlet pipe 3 can discharge the internal cold air into the interior of the heat generating area 18. When the two are in a disconnected state, the cold air inside the air outlet pipe 3 cannot enter the interior of the heat generating area 18. The electric valve on each air outlet 9 is controlled and operated by the controller 16, thereby controlling the cooling capacity of each heat generating area 18 by the controller 16, that is, the controller 16 controls the opening and closing of the electric valve according to the amount of heat generated by each heat generating area 18, thereby realizing temperature control of the heat generating area 18, that is, for high-power cabinets 4, the cooling capacity should be large, and for the heat generating area 18 corresponding to low-power cabinets 4, the cooling capacity should be small.

[0030] Furthermore, in order to better realize the distribution of cooling capacity, a temperature sensor 8 is also provided inside the heat generating area 18. The temperature sensor 8 is used to monitor the internal temperature of the corresponding heat generating area 18. The controller 16 controls the opening or closing of the electric valve according to the temperature signal of the temperature sensor 8. That is, when the temperature inside the heat generating area 18 is higher than the set threshold range, the controller 16 controls the corresponding electric valve to open. When the temperature inside the heat generating area 18 drops to an appropriate temperature, the controller 16 controls the electric valve to close. Since a temperature sensor 8 is provided inside each heat generating area 18, the controller 16 can supply cooling capacity according to the temperature inside each heat generating area 18.

[0031] Furthermore, a blower 15 is provided at the position of the air outlet 9. The blower 15 can quickly allow the cold air inside the air outlet 3 to enter the heat generating area 18, and at the same time quickly allow the hot air inside the heat generating area 18 to be discharged to the outside through the air outlet 7, thereby quickly cooling the heat generating area 18. Figure 6 As shown, when the temperature inside the corresponding heat generating area 18 is high, the controller 16 controls the electric valve to open while controlling the hair dryer 15 to work, so that the cold air inside the air outlet pipe 3 quickly enters the interior of the heat generating area 18.

[0032] Further, in order to enable those skilled in the art to better understand how the air outlet 9, the electric valve and the blower 15 are implemented, reference is made to Figure 5The utility model provides an implementation method, in which a mounting tube 10 is provided at the position of the air outlet 9, and a connecting hole 11 is opened on the side wall of the mounting tube 10. The electric valve includes a permanent magnet fixing ring 12, a guide rod 13, an electromagnet sliding ring 14 and a spring 17. When the controller 16 controls the electromagnet sliding ring 14 to be energized, the electromagnet sliding ring 14 generates magnetism and is adsorbed by the permanent magnet fixing ring 12, and slides along the guide rod 13 toward the permanent magnet fixing ring 12. The spring 17 is compressed, and the connecting hole 11 is in an open state. When the electromagnet sliding ring 14 is de-energized, the spring 17 resets and drives the permanent magnet fixing ring 12 to move to a state of blocking the connecting hole 11.

[0033] Furthermore, since hotter air tends to accumulate at the top and cooler air tends to accumulate at the bottom, in order to allow the air inside the data room to circulate better, the return air duct 2 should be set at a high place and the outlet air duct 3 should be set at a low place, such as Figure 2 In the figure, the return air duct 2 is arranged close to the inner wall of the roof of the data room, and the outlet air duct 3 is located in the floor 5 of the data room. Therefore, the return air duct 2 at a high position can recycle the hot air at a high position, and the outlet air duct 3 at a low position is more conducive to the stability of the cold air.

Those skilled in the art should understand that the present invention is not limited to the above-described embodiments.
