Description

Technical Field

[0001] This invention relates to a refrigeration cycle system, specifically a combined computer room refrigeration combined cycle system and its control method, belonging to the field of heat dissipation and refrigeration technology. Background Technology

[0002] The computer room is equipped with electronic computer systems, servers, communication systems, and other data processing, storage, and network communication equipment that operate 24 hours a day, 24 hours a year. These devices generate a lot of heat, causing the temperature in the computer room to rise. In order to ensure the normal operation of the equipment, uninterrupted cooling is required throughout the year.

[0003] The computer room air conditioner is used to cool the inside of the computer room. The air conditioner removes the heat generated by the electrical components of the server equipment in the computer room, thus providing an ideal temperature and humidity environment inside the communication computer room.

[0004] However, in the current application of computer room cooling systems, cold air is blown into the computer room through the air outlet of the computer room air conditioner. This causes the computer room equipment close to the computer room air conditioner to cool down quickly and the temperature difference between the inside and outside to be large, resulting in a significant increase in the humidity of the surrounding air. Meanwhile, the computer room equipment far away from the computer room air conditioner cools down slowly, and there may even be situations where the cooling effect of the equipment far away from the computer room air conditioner is poor due to the obstruction of the computer room equipment. Summary of the Invention

[0005] To solve the above problems, the present invention is implemented through the following technical solution: a combined computer room cooling combined cycle system and its control method, including a plate heat exchanger, a temperature sensor and a controller are provided at the bottom of the plate heat exchanger, a diversion pipe is provided on one side of the inlet and outlet of the plate heat exchanger, and two heat exchange pipes are provided between the two diversion pipes. The coolant circulates between the plate heat exchanger and the two heat exchange pipes to cool the inside of the computer room.

[0006] The heat exchange pipe is fitted with an air guide assembly, which includes a rubber plate, a partition plate, an air guide pipe, multiple heat dissipation pipes, an electric push rod, and a filter screen. One end of each of the multiple heat dissipation pipes passes through the heat exchange pipe. The hot air flowing inside the heat dissipation pipe exchanges heat with the coolant inside the heat exchange pipe. Condensation occurs inside the heat dissipation pipe. The hot air is cooled down and becomes cold air before being discharged into the machine room.

[0007] The top of the heat exchange pipe is equipped with a gas collection assembly, which includes a vacuum pump, a square air inlet pipe, a horizontal pipe, an air inlet pipe and a long pipe. The square air inlet pipe passes through the heat exchange pipe and the support frame. Multiple thin-walled pipes are fixedly connected inside the square air inlet pipe. The vacuum pump draws hot air from multiple parts inside the machine room through the long pipe to avoid the slow cooling speed and uneven cooling caused by the equipment in the machine room blocking the cold air.

[0008] A drainage assembly is provided between the two heat exchange pipes. The drainage assembly includes a V-shaped pipe, a storage tank, a solenoid valve, and a pressure sensor. The pressure sensor is electrically connected to an air pump and an electric push rod. The electric push rod connected to the pressure sensor moves the filter screen, adding a filtration function to the air guiding assembly. The cold air ejected from the heat dissipation pipe is filtered by the filter screen and discharged into the machine room. Dust and impurities in the gas are trapped inside the support frame by the filter screen.

[0009] Preferably, the temperature sensor is fixedly connected to one side of one of the air intake pipes. The temperature sensor monitors the temperature inside the computer room in real time and feeds it back to the electrically connected display screen. The staff can control the temperature inside the computer room according to the temperature value displayed on the display screen. The controller is fixedly connected to one side of the air intake pipe and includes a display screen, a first button, and a second button.

[0010] Preferably, the inlet and outlet ends of the plate heat exchanger are fixedly connected to two branch pipes, respectively, and the two ends of the heat exchange pipe are fixedly connected to adjacent branch pipes. Multiple installation vertical pipes are fixedly connected to the top and bottom of the heat exchange pipe. Multiple installation vertical pipes located at the bottom of the heat exchange pipe are fixedly connected to adjacent support frames. The plate heat exchanger is connected to the branch pipes through the guide bends, so the plate heat exchanger installed outside the machine room can be connected to the heat exchange pipes. The rubber plate and the air guide pipe are fixedly connected to the inside of the support frame on both sides. A partition plate is fixedly connected inside the support frame. The heat dissipation pipe discharges cold air into the relatively sealed space composed of the support frame, rubber plate, partition plate, and filter screen, which intercepts and blocks dust and impurities in the cold air.

[0011] Preferably, multiple heat dissipation pipes are fixedly connected to one side of the air guide pipe, and a diffuser pipe is fixedly connected to the top of the air guide pipe. A square pipe is fixedly connected between the diffuser pipe and the air outlet of the air pump. The air pump draws hot air from multiple parts inside the computer room through a square air inlet pipe, a horizontal pipe, an air inlet pipe, a long pipe, and multiple air inlets to increase the cooling speed inside the computer room.

[0012] Preferably, the electric push rod is fixedly connected to the top of the heat exchange pipe near the rubber plate, the filter screen is fixedly connected to one side of the electric push rod, one end of the filter screen is attached to the rubber plate, and the electric push rod is set on the top side of the rubber plate. The cold air is discharged into the relatively sealed space composed of the support frame, rubber plate, partition plate and filter screen, which intercepts and blocks dust and impurities in the cold air.

[0013] Preferably, the air pump is fixedly connected to the top of the heat exchange pipe, the top end of the square air inlet pipe is fixedly connected to the air inlet end of the air pump, the thin-walled tube is disposed inside the heat exchange pipe, and the top of the support frame is provided with a square groove. The coolant inside the heat exchange pipe passes through multiple thin-walled tubes and through the inside of the square air inlet pipe to cool the hot air flowing through the inside of the square air inlet pipe, which can provide preliminary cooling of the hot air. The bottom end of the square air inlet pipe passes through the square groove and is fixedly connected to the support frame to reduce condensation.

[0014] Preferably, the horizontal pipe is fixedly connected between the square air inlet pipe and the air inlet pipe, the long pipe is fixedly connected to the bottom of the air inlet pipe, and multiple air inlets are opened on one side of the long pipe. The multiple air inlets draw hot air from multiple parts inside the machine room. After the air collection component draws the hot air inside the machine room, it is delivered to the air guiding component. The air guiding component delivers the cooled hot air into the machine room.

[0015] Preferably, a drain bend is fixedly connected between the V-shaped tube and the two support frames. A water outlet hole is opened at the top of the support frame, and the drain bend is set at the bottom of the water outlet hole. The liquid enters the short tube through the drain bend and the V-shaped tube, and the liquid finally enters the storage tank through the short tube. A short tube is fixedly connected between the bottom of the V-shaped tube and the storage tank.

[0016] Preferably, the solenoid valve is fixedly connected to the bottom of the storage tank, and the top of the solenoid valve extends to the bottom of the inner cavity of the storage tank. When the solenoid valve is in the open state, the liquid is guided out by the drainage component. The outlet end of the solenoid valve is fixedly connected to a waste discharge pipe. When the solenoid valve is closed, the liquid is stored inside the storage tank. As the liquid inside the storage tank increases, the pressure sensor receives increased pressure. The pressure sensor is fixedly connected to the bottom of the inner cavity of the storage tank.

[0017] A control method for a combined cooling cycle system:

[0018] Step 1: The temperature sensor monitors the temperature inside the computer room in real time and feeds it back to the electrically connected display screen. Based on the temperature value displayed on the screen, the staff sets the desired temperature on the screen.

[0019] Step 2: Press the first button, and the plate heat exchanger and two gas collection components will work. The coolant will circulate between the plate heat exchanger and the two heat exchange pipes. After the coolant is cooled inside the plate heat exchanger, it will be discharged into the heat exchange pipe through another pipe system consisting of a guide bend, a branch pipe, and a through-wall pipe connected to the outlet of the plate heat exchanger.

[0020] Step 3: The air collection component works. The air pump draws hot air from multiple parts inside the computer room through a long pipe. The air pump draws hot air from multiple parts inside the computer room through a square air inlet pipe, a horizontal pipe, an air inlet pipe, a long pipe, and multiple air inlets, increasing the cooling speed inside the computer room and avoiding the situation where the computer room equipment blocks the cold air, resulting in slow cooling speed and uneven cooling.

[0021] Step 4: During the process of hot air being discharged through the air guide assembly connected to the air outlet of the air pump, it exchanges heat with the low-temperature coolant circulating inside the heat exchange pipe. After the hot air exchanges heat with the coolant inside the heat exchange pipe, it is discharged from one end of multiple heat dissipation pipes. The hot air is cooled into cold air and then discharged into multiple parts of the computer room to quickly and evenly cool the inside of the computer room.

[0022] Step 5: During the heat exchange process between hot air and coolant, condensation occurs inside the heat dissipation pipes, and the condensed liquid is collected by the working components into the drainage system.

[0023] Step Six: Press the second button. After the pressure sensor detects that the pressure has reached the preset value, the electric push rod will move the filter screen. One end of the filter screen will be in contact with the rubber plate. At this time, the heat dissipation pipe will discharge cold air into the relatively sealed space composed of the support frame, rubber plate, partition plate and filter screen, which will trap and block dust and impurities in the cold air and add a filtration function to the air guiding component. Dust and impurities in the cold air are trapped by the filter screen.

[0024] This invention provides a combined cooling system for computer rooms and its control method, which has the following beneficial effects:

[0025] 1. This combined cooling and circulation system for computer rooms and its control method involves an air collection component that extracts hot air from inside the computer room and then delivers it into the computer room through an air guide component. The hot air exchanges heat with the coolant circulating between the plate heat exchanger and two heat exchange pipes through the air guide component. The heat inside the computer room is carried away by the coolant. The coolant circulation cooling system, consisting of a plate heat exchanger, two guide bends, two branch pipes, four through-wall pipes, and two heat exchange pipes, works in conjunction with the airflow circulation system composed of the air collection component and the air guide component to form a combined cooling circulation system. The air collection component extracts hot air from multiple parts of the computer room, and the air guide component discharges cold air to multiple locations inside the computer room, increasing the cooling speed inside the computer room and avoiding slow or uneven cooling caused by the computer room equipment blocking the cold air. This ensures the protection of the computer room equipment through cooling.

[0026] 2. This combined cooling and control system for the computer room involves the following steps: After cooling inside the plate heat exchanger, the coolant enters the heat exchange pipes to absorb heat. The cooled coolant then returns to the plate heat exchanger for further cooling, circulating between the plate heat exchanger and the two heat exchange pipes. An air extraction pump draws hot air from multiple locations within the computer room through long pipes. The hot air is then discharged through multiple heat dissipation pipes in an air guide assembly (see below for details on the operation of the air guide assembly) connected to the pump's outlet. Since these heat dissipation pipes all penetrate the heat exchange pipes, the hot air exchanges heat with the low-temperature coolant circulating inside the pipes. The cooled air is then discharged into the computer room.

[0027] 3. The combined cooling cycle system for the computer room and its control method: During the operation of the combined cooling cycle system, the hot air flowing inside the heat dissipation pipe exchanges heat with the coolant inside the heat exchange pipe. Condensation occurs inside the heat dissipation pipe. The condensed liquid flows through one end of the heat dissipation pipe into the support frame. The condensed liquid is collected into the drainage component. At this time, the waste discharge pipe electrically connected to the first button is in the open state, and the liquid is guided out by the drainage component.

[0028] 4. This combined cooling and circulating system for the computer room and its control method involves the stored liquid applying pressure to a pressure sensor. When the pressure detected by the sensor reaches a preset value, the electrically connected electric actuator moves the filter screen. The moving filter screen adds a filtration function to the air guiding assembly. At this time, the cold air ejected from the heat dissipation pipes is filtered by the filter screen and discharged into the computer room. Dust and impurities in the air are trapped inside the support frame by the filter screen. The dust falls into the support frame, mixes with the liquid, and is collected by the drainage assembly, thus achieving a dust removal effect inside the computer room.

[0029] 5. The combined cooling and circulation system for the computer room and its control method: multiple thin-walled tubes are fixedly connected inside the square air inlet pipe. The coolant inside the heat exchange pipe passes through the multiple thin-walled tubes and passes through the inside of the square air inlet pipe to cool the hot air flowing through the square air inlet pipe. This can initially cool the hot air, reduce the temperature difference between the hot air and the coolant during the flow of the hot air inside the multiple small heat dissipation tubes, and reduce the occurrence of condensation.

[0045] This invention provides a combined computer room cooling system and its control method.

[0046] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 and Figure 14 The plate heat exchanger 1 includes a temperature sensor 35 and a controller 31 at its bottom. The temperature sensor 35 is fixedly connected to one side of one of the air inlet pipes 18, and the controller 31 is fixedly connected to one side of the air inlet pipe 18. The controller 31 includes a display screen 32, a first button 33 and a second button 36. A diversion pipe 3 is provided on both the inlet and outlet sides of the plate heat exchanger 1, and two heat exchange pipes 5 are provided between the two diversion pipes 3.

[0047] An air guiding assembly is fitted on the outside of the heat exchange pipe 5. The air guiding assembly includes a rubber plate 8, a partition plate 9, an air guiding pipe 10, multiple heat dissipation pipes 11, an electric push rod 21, and a filter screen 22. One end of each of the multiple heat dissipation pipes 11 passes through the heat exchange pipe 5. The inlet and outlet ends of the plate heat exchanger 1 are respectively fixedly connected to two branch pipes 3 with guide bends 2. Both ends of the heat exchange pipe 5 are fixedly connected to adjacent branch pipes 3 with through-wall pipes 4. Multiple installation vertical pipes 6 are fixedly connected to the top and bottom of the heat exchange pipe 5. The multiple installation vertical pipes 6 set at the bottom of the heat exchange pipe 5 are fixedly connected to adjacent support frames 7. The rubber plate 8 and the air guiding pipe 10 are respectively fixedly connected to the inside of the support frame 7 on both sides. The partition plate 9 is fixedly connected inside the support frame 7.

[0048] A gas collection assembly is provided at the top of the heat exchange pipe 5. The gas collection assembly includes a vacuum pump 12, a square air inlet pipe 15, a horizontal pipe 17, an air inlet pipe 18, and a long pipe 19. The square air inlet pipe 15 passes through the heat exchange pipe 5 and the support frame 7. Multiple thin-walled pipes 16 are fixedly connected inside the square air inlet pipe 15. Multiple air inlets 20 are opened on one side of the long pipe 19.

[0049] A drainage assembly is provided between the two heat exchange pipes 5. The drainage assembly includes a V-shaped pipe 24, a storage tank 26, a solenoid valve 27, and a pressure sensor 29. The pressure sensor 29 is electrically connected to the air pump 12 and the electric push rod 21.

[0050] Specifically, the heat exchange pipe 5 is installed on the ceiling of the computer room through multiple installation risers 6, the wall-penetrating pipe 4 passes through the computer room wall and is fixedly connected to the branch pipe 3 outside the computer room, and the plate heat exchanger 1 is connected to the branch pipe 3 through the guide bend 2. Therefore, the plate heat exchanger 1 installed outside the computer room can be connected to the heat exchange pipe 5.

[0051] After setting the temperature via the display screen 32 on the controller 31, the staff has two options:

[0052] Select option 1. Press the first button 33. The plate heat exchanger 1 and the two gas collection components electrically connected to the first button 33 will operate (see below for details on the operation of the gas collection components) to cool the computer room. When the plate heat exchanger 1 is working, the water pump at the inlet end draws coolant from the heat exchange pipe 5 through a piping system formed by the guide bend 2, the branch pipe 3, and the through-wall pipe 4. After the coolant is cooled inside the plate heat exchanger 1, it is discharged into the heat exchange pipe 5 through another piping system connected to the outlet end of the plate heat exchanger 1, which consists of the guide bend 2, the branch pipe 3, and the through-wall pipe 4. Therefore, after the coolant is cooled inside the plate heat exchanger 1, it enters the heat exchange pipe 5 to absorb heat. After absorbing heat, the coolant returns to the plate heat exchanger 1 to cool down, causing the coolant to circulate between the plate heat exchanger 1 and the two heat exchange pipes 5, thus cooling the computer room.

[0053] When the gas collection assembly is working, the vacuum pump 12 draws air through the long pipe 19. Two long pipes 19 are pre-installed on both sides inside the computer room, and the multiple air inlets 20 on the long pipes 19 make the air collection area of ​​the long pipes 19 wider. Therefore, after the vacuum pump 12 draws hot air from multiple parts inside the computer room through the long pipes 19, the hot air is discharged through multiple heat dissipation pipes 11 in the air guide assembly (see below for the operation of the air guide assembly) connected to the air outlet of the vacuum pump 12.

[0054] Furthermore, multiple heat dissipation pipes 11 all pass through the heat exchange pipe 5. Therefore, as the hot air flows inside the heat dissipation pipe 11, it exchanges heat with the low-temperature coolant circulating inside the heat exchange pipe 5. The hot air is cooled down and discharged into the computer room as cold air.

[0055] After the air collection component extracts hot air from inside the computer room, it is transported into the computer room through the air guide component. The hot air exchanges heat with the coolant circulating between the plate heat exchanger 1 and the two heat exchange pipes 5 through the air guide component. The heat inside the computer room is carried away by the coolant. The coolant circulation cooling system, consisting of the plate heat exchanger 1, two guide bends 2, two branch pipes 3, four through-wall pipes 4, and two heat exchange pipes 5, works in conjunction with the airflow circulation system consisting of the air collection component and the air guide component to form a combined refrigeration circulation system. The air collection component extracts hot air from multiple parts of the computer room, and the air guide component discharges cold air to multiple locations inside the computer room, increasing the cooling rate inside the computer room and avoiding slow or uneven cooling caused by the computer room equipment blocking the cold air. This ensures the protection of the computer room equipment through cooling.

[0056] Temperature sensor 35 monitors the temperature inside the computer room in real time and feeds it back to the electrically connected display screen 32. Staff can control the temperature inside the computer room based on the temperature values ​​displayed on the display screen 32.

[0057] During the operation of the combined refrigeration cycle system, the hot air flowing inside the heat dissipation pipe 11 exchanges heat with the coolant inside the heat exchange pipe 5. Condensation occurs inside the heat dissipation pipe 11, and the condensed liquid flows through one end of the heat dissipation pipe 11 into the support frame 7. The condensed liquid is collected by the drain assembly (see below for the operation of the drain assembly). At this time, the solenoid valve 27 electrically connected to the first button 33 is in the open state, and the liquid is guided out by the drain assembly.

[0058] Option 2: After setting the temperature via the display screen 32 on the controller 31, the operator presses the second button 36. The plate heat exchanger 1 and two gas collection components electrically connected to the second button 36 then operate (see below for details on the operation of the gas collection components) to cool the computer room. The cooling process is the same as that of the combined refrigeration cycle system in Option 1.

[0059] At this time, the wastewater discharge pipe 28, electrically connected to the second button 36, is in the working closed state, and the pressure sensor 29, electrically connected to the second button 36, is activated. The drainage assembly stores liquid. The stored liquid applies pressure to the pressure sensor 29. When the pressure detected by the pressure sensor 29 reaches a preset value, the electric push rod 21, electrically connected to the pressure sensor 29, activates, pushing the filter screen 22 to move. After the filter screen 22 moves, it adds a filtration function to the air guiding assembly. At this time, the cold air ejected from the heat dissipation pipe 11 is filtered by the filter screen 22 and discharged into the machine room. Dust and impurities in the air are trapped inside the support frame 7 by the filter screen 22. The dust falls into the support frame 7, mixes with the liquid, and is collected by the drainage assembly, thus achieving the effect of dust removal inside the machine room.

[0060] After the electric push rod 21, which is electrically connected to the pressure sensor 29, has been working for a period of time, the electric push rod 21 stops working and drives the filter screen 22 to reset. At the same time, the solenoid valve 27, which is electrically connected to the pressure sensor 29, opens, and the water stored in the drainage assembly is discharged through the solenoid valve 27.

[0061] Please refer to it again. Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 7 , Figure 8 and Figure 11 Multiple heat dissipation pipes 11 are fixedly connected to one side of the air guide pipe 10. A diffuser pipe 14 is fixedly connected to the top of the air guide pipe 10. A square pipe 13 is fixedly connected between the diffuser pipe 14 and the air outlet of the air pump 12. An electric push rod 21 is fixedly connected to the top of the heat exchange pipe 5 near the rubber plate 8. A filter screen 22 is fixedly connected to one side of the electric push rod 21. The electric push rod 21 is located on one side of the top of the rubber plate 8.

[0062] Specifically, the air guiding assembly works as follows:

[0063] Hot air discharged from the exhaust pump 12 enters the air guide pipe 10 through the square pipe 13 and the diffuser pipe 14. The hot air is then diverted into multiple heat dissipation pipes 11 fixedly connected to the air guide pipe 10. Thus, the hot air flows through the heat exchange pipes 5 within the multiple heat dissipation pipes 11. After exchanging heat with the coolant inside the heat exchange pipes 5, the hot air is discharged from one end of the multiple heat dissipation pipes 11, cooled into cold air, and then discharged into multiple parts of the computer room to cool the interior of the computer room.

[0064] Furthermore, the heat exchange pipe 5 is fixedly connected to a support frame 7 via multiple installation vertical pipes 6 on its outer side, and a partition plate 9 is fixedly connected inside the support frame 7. A rubber plate 8 is provided on one side of the heat dissipation pipe 11. When the electric push rod 21 pushes the filter screen 22 to move, one end of the filter screen 22 is in contact with the rubber plate 8. At this time, the heat dissipation pipe 11 discharges cold air into the relatively sealed space formed by the support frame 7, the rubber plate 8, the partition plate 9, and the filter screen 22, which intercepts and blocks dust and impurities in the cold air, adding a filtration function to the air guiding component.

[0065] Please refer to it again. Figure 1 , Figure 4 , Figure 6 , Figure 7 , Figure 8 and Figure 9 The air pump 12 is fixedly connected to the top of the heat exchange pipe 5. The top end of the square air inlet pipe 15 is fixedly connected to the air inlet end of the air pump 12. The thin-walled pipe 16 is set inside the heat exchange pipe 5. The top of the support frame 7 has a square groove 34. The bottom end of the square air inlet pipe 15 passes through the square groove 34 and is fixedly connected to the support frame 7. The horizontal pipe 17 is fixedly connected between the square air inlet pipe 15 and the air inlet pipe 18. The long pipe 19 is fixedly connected to the bottom of the air inlet pipe 18.

[0066] Specifically, the gas collection component works as follows:

[0067] A square air inlet pipe 15 is fixedly connected to the air inlet end of the air pump 12, and the square air inlet pipe 15 is connected to the long pipe 19 through the horizontal pipe 17 and the air inlet pipe 18. The long pipe 19 extends from one end of the machine room to the other end. Therefore, the distribution of multiple air inlets 20 enables the long pipe 19 to connect with multiple locations inside the machine room.

[0068] The working air pump 12 extracts hot air from multiple parts inside the machine room through a square air inlet pipe 15, a horizontal pipe 17, an air inlet pipe 18, a long pipe 19, and multiple air inlets 20. The air outlet of the air pump 12 is fixedly connected to the square pipe 13 of the air guide assembly. Therefore, after the air collection assembly extracts the hot air inside the machine room, it delivers it to the air guide assembly, which then cools and delivers the hot air into the machine room.

[0069] Furthermore, multiple thin-walled tubes 16 are fixedly connected inside the square air intake pipe 15. The coolant inside the heat exchange pipe 5 passes through the multiple thin-walled tubes 16 and passes through the inside of the square air intake pipe 15 to cool the hot air flowing through the square air intake pipe 15. This can initially cool the hot air, reduce the temperature difference between the hot air and the coolant during the flow of the hot air inside the multiple small heat dissipation tubes 11, and reduce the occurrence of condensation.

[0070] Please refer to it again. Figure 1 , Figure 10 , Figure 12 , Figure 13 and Figure 14 Drainage bends 23 are fixedly connected between the V-shaped tube 24 and the two support frames 7. A water outlet 30 is opened at the top of the support frame 7. The drainage bend 23 is located at the bottom of the water outlet 30. A short pipe 25 is fixedly connected between the bottom of the V-shaped tube 24 and the storage tank 26. A solenoid valve 27 is fixedly connected to the bottom of the storage tank 26. The top of the solenoid valve 27 extends to the bottom of the inner cavity of the storage tank 26. A waste discharge pipe 28 is fixedly connected to the water outlet of the solenoid valve 27. A pressure sensor 29 is fixedly connected to the bottom of the inner cavity of the storage tank 26.

[0071] Specifically, the drainage components work as follows:

[0072] The water outlet 30 inside the support frame 7 guides the liquid accumulated inside the support frame 7 into the drain bend 23. The liquid then enters the short pipe 25 through the drain bend 23 and the V-shaped pipe 24, and finally enters the storage tank 26 through the short pipe 25. When the pressure sensor 29 and the solenoid valve 27 are working, the solenoid valve 27 closes, causing the liquid to be stored inside the storage tank 26. As the amount of liquid inside the storage tank 26 increases, the pressure on the pressure sensor 29 increases. When the pressure detected by the pressure sensor 29 reaches a preset value, the electric push rod 21 electrically connected to the pressure sensor 29 operates, pushing the filter screen 22 to move, adding a filtration function to the air guiding assembly.

[0073] A control method for a combined cooling cycle system:

[0074] Step 1: Temperature sensor 35 monitors the temperature inside the computer room in real time and feeds it back to the electrically connected display screen 32. The staff sets the temperature on the display screen 32 according to the temperature value displayed on the display screen 32.

[0075] Step 2: Press the first button 33. The plate heat exchanger 1 and the two gas collection components will work. The coolant will circulate between the plate heat exchanger 1 and the two heat exchange pipes 5. After the coolant is cooled inside the plate heat exchanger 1, it will be discharged into the heat exchange pipe 5 through another pipe system consisting of a guide bend 2, a diversion pipe 3, and a through-wall pipe 4 connected to the outlet of the plate heat exchanger 1.

[0076] Step 3: The air collection component works. The air pump 12 draws hot air from multiple parts inside the computer room through the long pipe 19. The air pump 12 draws hot air from multiple parts inside the computer room through the square air inlet pipe 15, the horizontal pipe 17, the air inlet pipe 18, the long pipe 19, and multiple air inlets 20, which increases the cooling speed inside the computer room and avoids the situation of slow cooling speed and uneven cooling caused by the computer room equipment blocking the cold air.

[0077] Step 4: During the process of hot air being discharged through the air guide assembly connected to the air outlet of the air pump 12, it exchanges heat with the low-temperature coolant circulating inside the heat exchange pipe 5. After the hot air exchanges heat with the coolant inside the heat exchange pipe 5, it is discharged from one end of multiple heat dissipation pipes 11. The hot air is cooled down into cold air and then discharged into multiple parts of the computer room to quickly and evenly cool the inside of the computer room.

[0078] Step 5: During the heat exchange process between hot air and coolant, condensation occurs inside the heat dissipation pipe 11, and the condensed liquid is collected into the drainage assembly.

[0079] Step Six: Press the second button 36. After the pressure detected by the pressure sensor 29 reaches the preset value, the electric push rod 21 works to push the filter screen 22 to move. One end of the filter screen 22 is in contact with the rubber plate 8. At this time, the heat dissipation pipe 11 discharges cold air into the relatively sealed space composed of the support frame 7, the rubber plate 8, the partition plate 9, and the filter screen 22, which intercepts and blocks dust and impurities in the cold air, adding a filtration function to the air guiding component. Dust and impurities in the cold air are intercepted by the filter screen 22.

[0080] Furthermore, step six can replace step two, providing two modes for cooling the computer room and ensuring that the computer room is cooled according to actual needs.
