Abstract
Description
[0001] This application is a divisional application of a patent application with an application date of October 16, 2024, application number 202411441990.2, and invention name “Condenser tube group and falling film condenser, condensation method and refrigeration system using the same”. Technical Field
[0002] The present invention relates to the field of condensers, and in particular to a condensation fluid transmission structure and a condensation balanced air inlet method. Background Art
[0003] In a refrigeration system, the evaporator, condenser, compressor, and expansion valve are the four essential components. The evaporator is the device that delivers cooling capacity. The refrigerant absorbs heat from the object being cooled, creating cooling. The compressor is the heart of the system, responsible for drawing in, compressing, and transporting the refrigerant vapor. The condenser is the device that releases heat, transferring the heat absorbed in the evaporator, along with the heat converted by the compressor, to the cooling medium. The expansion valve throttles and reduces the pressure of the refrigerant, controlling and regulating the amount of refrigerant liquid flowing into the evaporator and dividing the system into two major sections: the high-pressure side and the low-pressure side. In addition to the four major components mentioned above, a practical refrigeration system often includes a number of auxiliary equipment, such as solenoid valves, distributors, dryers, collectors, fusible plugs, and pressure controllers, to enhance operational efficiency, reliability, and safety.
[0004] The condenser is a component of the refrigeration system and a type of heat exchanger. It converts gas or vapor into liquid, quickly transferring heat from the condenser tubes to the surrounding air. The condenser's operating process is exothermic, so the condenser temperature is always relatively high. There are several different types of condensation systems. Water-cooled condensers use water as the cooling medium, with the rising temperature of the water removing the condensation heat. The cooling water is generally recycled, but a cooling tower or cooling water tank is required in the system. Water-cooled condensers can be divided into shell-and-tube condensers and double-tube condensers based on their structure, with the shell-and-tube condenser being the most common. Air-cooled condensers use air as the cooling medium, with the rising temperature of the air removing the condensation heat. This type of condenser is suitable for applications where water is extremely scarce or unavailable, and is commonly found in small Freon refrigeration units.
[0005] The evaporative condenser is the primary heat exchanger in the refrigeration system. Its operating principle is as follows: the hot, high-pressure refrigerant gas discharged from the compressor passes through the condenser tubes within the evaporative condenser, exchanging heat with the spray water and air outside the tubes. The gaseous refrigerant enters the tubes from the top and gradually condenses from top to bottom into liquid refrigerant. The powerful induced draft fan ensures that the spray water evenly coats the coil surface, significantly enhancing heat exchange efficiency. The heated spray water partially vaporizes, where the wind removes a significant amount of heat, utilizing its latent heat of vaporization. Water droplets trapped in the hot vapor are trapped by a high-efficiency dehydrator and, along with the remaining heat-absorbed water, are dispersed into the heat exchange layer of the PVC spray sheet. There, cooled by the passing air, the water enters the water tank and continues to circulate through the circulating water pump. The water evaporated into the air is automatically replenished by a water level regulator.
[0006] After years of development, the condenser technology is relatively mature, but there are still at least the following deficiencies: 1. In an existing evaporative condenser, a fan and a water distribution pipe are located at the top, a condenser is located below the water distribution pipe, a filler is located below the condenser, and a water tank is located at the bottom of the filler. The water is drained downwards by the water distribution pipe, and the water flows downwards. There is an air inlet on the side, which is located lower than the filler and the condenser, but higher than the water tank. When the fan is started, the air is sucked in from the bottom up through the air inlet. The sucked air first passes through the filler, which guides the wind, and the water flows downwards on the filler. There is a water tank at the bottom for collecting the cooled water. In the process of the filler causing the water to flow downwards, the contact area and time between the wind and water are increased, so that the wind can take away more heat. During the whole process, the directions of the wind and water are reversed, and the water will block the air intake, making the wind distribution uneven.
[0007] 2. Evaporative cooling relies on the contact of water on the surface of the condenser tube, thereby reducing the evaporation temperature of the refrigerant as low as possible. As for how low it is, it depends on the amount of water, the amount of air, and most importantly, the inlet air temperature. The lower the temperature of the incoming air, the lower the evaporation temperature. If the temperature of the wind is high when it contacts the condenser tube, the evaporation temperature will be high, and the condensation effect will be greatly reduced. The existing design has a big disadvantage. After the wind enters, it will first pass through the packing when exchanging heat with the condenser. It can cool the water in the packing, but cooling the water is not the key point. The key point is to keep the condensation temperature low. However, the wind passes through the packing first, and the temperature of the wind has risen at this time. As a result, the temperature of the wind after passing through the packing is not as low as before when it contacts the condenser tube. This is not good for condensation, because the essential purpose is to cool the condenser tube to maximize efficiency and achieve phase change, not just to reduce the temperature of the water. Therefore, the filler has few positive advantages and a greater negative impact. However, since the filler is one of the necessary accessories, it cannot be deleted. If the filler is removed, the wind guidance and uniformity will not be so good. Based on this, the technical personnel in the industry have not paid attention to this aspect, and it is also the consensus of the industry that the wind goes from below. This has formed a common prejudice in the industry, and people do not think that this aspect has an impact. Therefore, everyone in the industry has ignored this issue.
[0008] 3. Currently, the pipes on the condenser are all placed horizontally. Since the refrigerant entering the condenser is in gaseous state, and the refrigerant after condensation is in liquid state, and the liquid refrigerant in the horizontally arranged pipes will not actively flow forward, a large amount of liquid refrigerant will remain in each pipe; the liquid refrigerant in the pipe is completely driven forward by the pressure in the pipe, and even when the compressor pushes the fluid forward, a large amount of liquid refrigerant will remain in the pipe, occupying a large amount of space in the condenser tube; currently, most of the refrigerant flowing forward in the condenser is gaseous refrigerant, and a lot of liquid refrigerant remains in the pipe. Usually, the liquid refrigerant in the condenser tube will only flow forward when it exceeds a certain amount.
[0009] 4. With the existing condenser, there is still a considerable amount of liquid refrigerant in the condenser tube that has not flowed into the end close to the evaporator until the entire refrigeration unit is shut down. On the one hand, this causes waste and affects efficiency; on the other hand, when the refrigeration unit is just started, the refrigerant sucked into the evaporator is sometimes mixed with gaseous refrigerant, while liquid refrigerant remains in the condenser tube.
[0010] 5. There is a certain amount of liquid refrigerant remaining in each section of the condenser tube. However, there are a lot of condenser tubes in a condenser. When these large number of condenser tubes are added together, the amount of liquid refrigerant remaining in the tube is quite large.
[0011] 6. In the prior art, there are also vertically arranged condenser tubes, which has a greater disadvantage. Because the vertical arrangement of the condenser tubes causes the condenser tubes to be at different heights, it is more unfavorable for the flow of refrigerant, and the amount of liquid refrigerant remaining in the condenser tubes is greater; liquid refrigerant will be deposited at the bottom of each tube, in this case there will be liquid refrigerant at the bottom. The present invention is tilted, so there will be no liquid refrigerant in the tubes.
[0012] 7. Regardless of the design of the condenser, liquid refrigerant will remain in the condenser and cannot flow to the evaporator. In the use of the refrigeration unit, the main function of the condenser is to remove heat and realize the phase change of gaseous refrigerant into liquid. In the process of heat exchange, the gaseous refrigerant is in a process of continuous transformation into liquid. In this process, the liquid refrigerant in the condenser increases. At this time, if the liquid refrigerant can be discharged in time, a larger area will be reserved for the condenser for heat exchange with the new gaseous refrigerant, so that more gaseous refrigerant can be transformed into liquid. , thereby achieving higher efficiency; however, there is liquid refrigerant that has not been discharged in the condenser tube, and this liquid refrigerant will reduce the area of the condenser tube for heat exchange; especially where the pipeline has high and low inclination angles or slight bends, the liquid refrigerant is deposited more in the concave position, and the heat exchange area is reduced even more. When the machine is turned on, the power of the machine is higher, but the efficiency is not improved by the same amount. The cooling capacity of the refrigeration unit is not proportional to the power; these situations are problems that have not been discovered in the existing industry, but this problem has a great impact on the condensation efficiency.
[0013] 8. The applicant is Guangdong Anjia Air Conditioning and Refrigeration Co., Ltd., and the applicant's own existing patent, China Patent Authorization Announcement No.: CN115615054B, the patent name is: A curtain-type condenser, including the prior art, because the end of the condenser tube is narrowed, it also further causes at least a part of the liquid refrigerant in each condenser tube to be stored inside and unable to come out. However, if the end of the condenser tube is not narrowed, it is not conducive to achieving good sealing when welding the main tube.
[0014] 9. In the existing condenser, the downward flowing water film increases the contact between water and the condenser tube, but it also forms a series of water walls, blocking the flow range of the wind, so that part of the wind cannot blow to the condenser tube near the inside; however, if the wind is turned up a little higher, it can pass through the water film, but it will blow away the water on the surface of the condenser tube. Therefore, this is a big contradiction at present.
[0015] 10. Currently, liquid refrigerant will remain in the condenser tube, and the liquid refrigerant occupies the space of the condenser tube, reducing the area of the condenser tube for heat exchange, wasting the power of the compressor and condenser, and reducing the condensation volume. It is necessary to increase the amount of cold water and lower the cold water temperature to achieve efficient condensation.
[0016] 11. In the existing condenser pipe, water mainly covers the surface of the condenser pipe body, and the condenser pipe at the bend cannot be covered by water, so that the water flow of the entire condenser pipe is interrupted at the bend. Summary of the Invention

[0028] As a preferred embodiment of the condensation method of the present invention, a condensation tube group at an inclined angle is used to achieve a wider air inlet; Utilize buffer space to achieve more even distribution of cold air.
[0029] The refrigeration system of the present invention includes any of the falling film condensers described above, wherein the first liquid condenser tube and the second liquid condenser tube in the falling film condenser are connected to an expansion valve, the expansion valve is connected to an evaporator, the evaporator is connected to a compressor, and the compressor is connected to the first gaseous condenser tube and the second gaseous condenser tube of the condenser.
[0030] Beneficial effects The present invention solves the above existing problems and other existing problems not mentioned above and accordingly brings at least the following innovative advantages: The condenser tube group of the present invention and the falling film condenser, condensation method and refrigeration system using the condenser tube group are respectively at an inclined angle, so that the entire condenser tube group is at an inclined angle, so that during use, the air inlet surface is increased, thereby solving the contradiction between the size of the air inlet and the volume of the condenser in the prior art.
[0031] The condenser tube assembly of the present invention and the falling film condenser, condensation method, and refrigeration system using the same, by changing the position of the air inlet, setting the air inlet on the side of the condenser main box, and more importantly, above the condensation bin, and changing the air inlet direction from above, so that the air inlet and water distribution flow directions are the same, thereby preventing water from being blown away from the surface of the condenser tube and preventing the condenser tube from being exposed; The condenser tube group of the present invention and the falling film condenser, condensation method and refrigeration system using the same, since the air inlet is arranged on the side, solves the problems of large air intake volume and volume, and also plays a role in being away from the fan, making it difficult to suck in the hot air from the fan, thereby solving the problem of the current technical solution that the hot air from the fan is easily sucked back.
[0032] The condenser tube group of the present invention and the falling film condenser, condensation method and refrigeration system using the same achieve upper air intake due to the position of the air inlet being higher than the condenser tube group; and a buffer space is also provided in the condenser bin, so that the wind can pass evenly between the water films of the condenser tube group, thereby solving the problems in the prior art where side air intake will blow away the water on the surface of the condenser tube, and the existing condenser tube will block the air intake.
[0033] The condenser tube group of the present invention and the falling film condenser, condensation method and refrigeration system using the same have the same air inlet direction and water flow direction, and the wind passes through the water films. While taking away heat, the water on the surface of the condenser tube will not be blown away. This solves the problem in the prior art that if any part of the surface of the condenser tube is not covered with water, then the entire larger area below that position will not be covered with water, seriously affecting the condensation effect.
[0034] The condenser tube group of the present invention and the falling film condenser, condensation method and refrigeration system using the same have the same air inlet direction and water flow direction, and the wind passes through the water films, which will not blow away the water on the surface of the condenser tube. On the one hand, it is conducive to taking away heat, and on the other hand, the wind is more evenly distributed, which solves the problems that water will block the air inlet, wind will blow away the water on the surface of the condenser tube, and water will cause uneven wind distribution; it also solves the problem in the prior art that the wind first contacts the filler and then heats up.
[0035] The condenser tube group of the present invention and the falling film condenser, condensation method and refrigeration system using the condenser tube group, the incoming air first contacts the first condenser tube and the second condenser tube, which more effectively improves the efficiency. In addition, the condenser tube group of the present invention is at an inclined angle, and the first pipe body and the second pipe body are arranged vertically, and the flow directions of water and wind are the same. Therefore, on the one hand, the problem of temperature increase caused by filler is solved. On the other hand, the present invention can do without filler and can delete filler, changing the traditional prejudice in the industry. In the absence of filler, the wind guidance is still very good, and the cost is low, while the efficiency can be improved.
[0036] The condenser tube group of the present invention and the falling film condenser, condensation method and refrigeration system using the condenser tube group, the first condenser tube and the second condenser tube in the condenser tube group of the present invention are at an inclined angle, and the first condenser tube and the second condenser tube form a vertical row under the inclined angle, and the liquid refrigerant in the first condenser tube and the second condenser tube can quickly flow into the first liquid condenser tube and the second liquid condensing refrigerant tube, leaving a larger contact area for the first condenser tube and the second condenser tube to perform heat exchange in real time, so that the phase change of the refrigerant is more efficient and more sufficient. Moreover, even if the power of the refrigeration unit is turned on a little lower, the refrigeration capacity of the evaporator will not be affected due to the improvement of the heat exchange capacity, thereby saving the condensation cost and greatly improving the efficiency. Because the heat exchange area is large, the phase change conversion rate of the refrigerant is higher, and the efficiency of the refrigeration unit can be the same or similar to the original high power when the power is turned on at a low power.
[0037] The condenser tube group of the present invention and the falling film condenser, condensation method and refrigeration system using the condenser tube group are at an inclined angle, so the liquid refrigerant in all the first condenser tubes and the second condenser tubes can flow forward better, which solves the current problems of liquid refrigerant occupying space in the condenser tubes and low heat exchange efficiency, and at the same time provides a large amount of refrigerant for the evaporator, bringing about the effect of one plus one being greater than two.
[0038] The condenser tube assembly of the present invention, the falling film condenser, the condensation method, and the refrigeration system using the same, enable the liquid refrigerant in the first and second condenser tubes to slowly flow forward without the compressor's force, even after the refrigeration unit is shut down. This ensures that only gaseous refrigerant remains in the first and second condenser tubes. This also facilitates the next startup of the unit, as more liquid refrigerant is immediately supplied to the evaporator. This solves the problem in current refrigeration equipment where a large amount of liquid refrigerant remains in the condenser tubes until the system is shut down, while some gaseous refrigerant is drawn into the evaporator.
[0039] The condenser tube group of the present invention and the falling film condenser, condensation method and refrigeration system using the same are such that, since the first condenser tube and the second condenser tube are always in an inclined state and the position of the inlet end is higher than the outlet end, it is not easy for liquid refrigerant to remain in the condenser tubes whether the refrigeration unit is in operation or in a shutdown state, and the serious liquid refrigerant residue problem caused by the current vertical arrangement of the condenser tubes is solved.
[0040] The condenser tube group of the present invention and the falling film condenser, condensation method and refrigeration system using the same, because the first condenser tube and the second condenser tube are always in an inclined state, the liquid refrigerant can be discharged in real time, and even if the condenser tube is bent, liquid refrigerant is not easily accumulated; compared with the existing technology, the heat exchange area is increased and the efficiency is high; it solves the current problem that the liquid refrigerant is deposited more due to the high and low inclination angles or slight bends of the condenser tube, which further reduces the heat exchange area and causes the cooling capacity of the refrigeration unit to be not proportional to the power. The present invention greatly improves the heat transfer efficiency compared with the existing technology under the conditions of equal volume and open power.
[0041] The condenser tube group of the present invention and the falling film condenser, condensation method and refrigeration system using the same, because the first condenser tube and the second condenser tube are always in an inclined state, so that the liquid refrigerant can flow smoothly, and solves the current problem that the ends of the condenser tubes are narrowed, which further causes at least a portion of the liquid refrigerant in each condenser tube to be stored inside and unable to come out.
[0042] The condenser tube group of the present invention and the falling film condenser, condensation method and refrigeration system using the condenser tube group, since the first condenser tube and the second condenser tube are spaced apart; and the inlet end of the first condenser tube and the inlet end of the second condenser tube are in opposite directions; the outlet end of the first condenser tube and the outlet end of the second condenser tube are in opposite directions; therefore, the present invention solves the problem that when the number of arranged condenser tubes is too large, the ends of the condenser tubes can achieve good sealing without being narrowed.
[0043] The condenser tube group of the present invention and the falling film condenser, condensation method and refrigeration system using the condenser tube group, by installing the condenser tube group above the condensation bin and combining the design of the air inlet and the buffer space, can allow air to enter from above, the wind first contacts the condenser tube, and the incoming air flows along the gaps in the water film, thereby solving the problem of not blowing away the water on the surface of the condenser tube and exposing the condenser tube, and solving the problem of the water film blocking the air intake in the prior art, thereby overcoming the existing contradictory problems.
[0044] The condenser tube group of the present invention and the falling film condenser, condensation method and refrigeration system using the same can discharge the liquid refrigerant in time, thereby solving the current problem that the liquid refrigerant occupies the space of the condenser tube, reduces the area of the condenser tube for heat exchange, wastes the power of the compressor and condenser, and reduces the condensation amount. It also solves the current problem that condensation needs to be achieved by increasing the amount of cold water and lowering the cold water temperature.
[0045] Furthermore, when the condensed water is drained on the first pipe body, since the first condenser tube and the second condenser tube are inclined at different angles, the water can also at least partially flow to the first bend, thereby increasing the heat exchange area and solving the problem that heat exchange cannot be performed at the current bend.

[0048] In order to make the purpose, technical solutions and advantages of the technical solutions of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the specific embodiments of the present disclosure.
[0049] The same reference numerals in the accompanying drawings represent the same components. It should be noted that the embodiments described are only part of the embodiments of the present disclosure, rather than all the embodiments.
[0050] Based on the described embodiments of the present disclosure, all other embodiments obtained by those skilled in the art without creative work shall fall within the scope of protection of the present disclosure.
[0051] In the existing technology, there are still more problems in implementation, including at least: First, the heat dissipation of the condenser is proportional to the air inlet volume and air inlet temperature. If the air inlet is small, the air inlet volume will decrease and the wind speed will increase. The high wind speed will further blow away the water on the surface of the condenser tube, leaving the surface of the condenser tube without water and exposed, seriously affecting the condensation efficiency. At the same time, when the wind speed is too fast, the blowing is more uneven. However, if the air inlet is set too large in the existing technology, it will either cause the volume of the whole machine to increase. The solution is either to reduce the number of condenser tubes or to increase the height of the condenser. It is impossible to achieve a large air inlet while keeping the volume of the condenser unchanged. Therefore, in the existing technology, the size of the air inlet and the volume of the condenser are a contradiction. It is impossible to set a large air inlet when the volume is small. Secondly, in the existing condenser, the air and water flow in opposite directions. Even if the air inlet position is changed to the top or the left and right sides so that the cold air contacts the condenser tube first, this will make the condenser larger and inconvenient to transport. In addition, the width of the air inlet is narrow, and the air flow in the condenser is more uneven, which further makes it impossible for water to exist on the surface of the condenser tube, thereby increasing the exposed area. Third, further, under the existing technology, even if the air inlet position is changed to the top or the left and right sides, in actual use, the air inlet will suck in the hot air discharged by the fan, causing the hot air to circulate, resulting in the blowing of hot air, greatly reducing the condensation efficiency, and may even prevent the refrigerant from completing the phase change from gas to liquid; Fourthly, in order to enlarge the air inlet, the air inlet can be set on the side in the existing technology. Then, a large air inlet can be achieved. However, if the air inlet is changed to the side in the existing technology, the wind will also blow away the water on the surface of the condenser tube, leaving a large area of the condenser tube surface exposed and not covered by water. In addition, the condenser tube will also block the air inlet, greatly reducing the condensation effect. Fifth, once there is no water covering the surface of any part of the condenser tube, the entire larger area below that position will not be covered by water, seriously affecting the condensation effect.
[0052] The following are specific embodiments of the present invention.

Specifically, the falling film condenser of the present invention includes: the condenser tube group of embodiment 1; Figure 10 The present invention is shown to be installed with at least two condenser tube groups; Also includes a condenser main box 13, see Figure 10 The condenser main box 13 has an exhaust passage 14 in the middle and condensation chambers 15 on both sides of the exhaust passage 14; a fan 16 is provided vertically above the condenser main box 13, and the fan 16 is connected to the exhaust passage 14; a water pool 17 is provided below the condenser main box 13; like Figure 10 As shown, the condensation bin 15 is connected to another condensation bin 15 and the exhaust passage 14 through the hollow area above the water pool 17; See also Figure 10 and Figure 11 , each of the condensation bins 15 has an air inlet 23 on the upper side; Figure 10 It shows that each of the condensing bins 15 is respectively installed with the condensing pipe group described in Example 1, and the condensing pipe group covers the cross section of the condensing bin 15, that is, see Figure 10 When wind blows through the condensation chamber 15 , it must pass through the condensation tube group; the condensation tube group is located above the condensation chamber 15 as a whole.

[0061] For further information, see Figure 10 and Figure 11 A buffer space 19 is provided above each of the condensation bins 15 , and the buffer space 19 is at the same level as the air inlet 23 .
[0062] For further information, see Figure 6 、 Figure 7 and Figure 8 , including a main water pipe 20, the main water pipe 20 is at an inclined angle, and the main water pipe 20 is connected to at least three water distribution pipes 21, Figure 6 and Figure 8There are multiple water distribution pipes 21, the number of which is the same as that of the first pipeline body 2; at least three of the water distribution pipes 21 are distributed in a stepped manner and are on the same oblique line; Figure 7 It is shown that each water distribution pipe 21 has an outlet 22 below; the inclination angle of the water pipe matches the inclination angle of the first condenser pipe 1; A water distribution pipe 21 is provided above each of the first pipe bodies 2 at the top in the condensing pipe group, and an outlet 22 of the water distribution pipe 21 is adjacent to the vertical upper surface of the first pipe body 2 .
[0063] When the water distribution pipe 21 drains water downward, the condensed water forms a vertical water film with at least each row of the first pipe body 2 and the second pipe body 7 in the condenser tube group, so that the condensed water exchanges heat with the first condenser tube 1 and the second condenser tube 6 in the condenser tube group and the gaseous refrigerant completes the phase change; Figure 7 As shown, the water film forms an oblique angle with the flow direction of the gaseous refrigerant and flows downward respectively; when the fan 16 is started to exhaust air outward, the external fresh air is sucked in from the position of the air inlet 23, and passes through at least the condenser tube group and the top of the water pool 17 and is finally discharged through the exhaust channel 14; see Figure 11 , Figure 11 An air flow effect diagram was drawn, in which the cold air flows vertically downward from the gap between each two drainage membranes, exchanges heat with the condenser tube and condensed water, takes away heat, and causes the gaseous refrigerant to change phase.
[0064] Example 3 The falling film condenser of the present invention, in this embodiment 2, includes all aspects of the embodiment 1; therefore, the similarities with the embodiment 1 are not repeated here, and only the differences are described here. Specifically, the falling film condenser of the present invention eliminates the filler 18 of the prior art and consists only of the condenser tube assembly and condenser main box 13 of the embodiment 1. like Figure 12 As shown, the condenser main box 13 is composed of: an exhaust duct 14 in the middle, and condensation chambers 15 on both sides of the exhaust duct 14; a fan 16 is provided vertically above the condenser, and the fan 16 is connected to the exhaust duct 14; a water pool 17 is provided below the condenser; the condensation chamber 15 is connected to the exhaust duct 14 through the top of the water pool 17; Each of the condensation bins 15 has an air inlet on its upper side; Each of the condensing bins 15 is respectively equipped with the condensing pipe group, and the condensing pipe group covers the cross section of the condensing bin 15. Figure 10When wind blows through the condensation chamber 15 , it must pass through the condensation tube group; the condensation tube group is located above the condensation chamber 15 as a whole.
[0065] For further information, see Figure 12 A buffer space 19 is provided above each of the condensation bins 15 , and the buffer space 19 is at the same level as the air inlet 23 .
[0066] For further information, see Figure 6 、 Figure 7 and Figure 8 , including a main water pipe 20, the main water pipe 20 is at an inclined angle, and the main water pipe 20 is connected to at least three water distribution pipes 21, Figure 6 and Figure 8 There are multiple water distribution pipes 21, the number of which is the same as that of the first pipeline body 2; at least three of the water distribution pipes 21 are distributed in a stepped manner and are on the same oblique line; Figure 7 It is shown that each water distribution pipe 21 has an outlet 22 below; the inclination angle of the water pipe matches the inclination angle of the first condenser pipe 1; A water distribution pipe 21 is provided above each of the first pipe bodies 2 at the top in the condensing pipe group, and an outlet 22 of the water distribution pipe 21 is adjacent to the vertical upper surface of the first pipe body 2 .
[0067] When the water distribution pipe 21 drains water downward, the condensed water forms a vertical water film with at least each row of the first pipe body 2 and the second pipe body 7 in the condenser tube group, so that the condensed water exchanges heat with the first condenser tube 1 and the second condenser tube 6 in the condenser tube group and the gaseous refrigerant completes the phase change; Figure 7 As shown, the water film forms an oblique angle with the flow direction of the gaseous refrigerant and flows downward respectively; when the fan 16 is started to exhaust air outward, the external fresh air is sucked in from the position of the air inlet 23, and passes through at least the condenser tube group and the top of the water pool 17 and is finally discharged through the exhaust channel 14; see Figure 11 , Figure 11 An air flow effect diagram was drawn, in which the cold air flows vertically downward from the gap between each two drainage membranes, exchanges heat with the condenser tube and condensed water, takes away heat, and causes the gaseous refrigerant to change phase.
[0068] Example 4 The condensation method of the present invention adopts the condenser tube assembly of Example 1 or the entire scheme of the falling film condenser of Examples 2 and 3; Obtaining a gaseous refrigerant, which is condensed from a high-temperature and high-pressure gaseous refrigerant supplied by a compressor of a refrigeration device; the gaseous refrigerant flows obliquely downward along the first condensing tube 1 and the second condensing tube 6 of the condensing tube group; The condensed water is obtained from the water discharged from the water distribution pipe 21, and the condensed water is distributed vertically downward; see Figure 6 、 Figure 7 and Figure 8 When the water distribution pipe 21 drains water downward, the condensed water forms a vertical water film with at least each row of the first pipe body 2 and the second pipe body 7 in the condenser tube group, so that the condensed water exchanges heat with the first condenser tube 1 and the second condenser tube 6 in the condenser tube group and the gaseous refrigerant completes the phase change; Figure 7 As shown, the water film forms an oblique angle with the flow direction of the gaseous refrigerant and flows downward respectively; Get cool air, such as Figure 10 and Figure 12 As shown, the cold air comes from the fan 16 that is started and exhausted outward, sucking in the outside fresh air from the air inlet 23, and passing through at least the condenser tube group and the top of the pool 17 and finally discharged through the exhaust channel 14; see Figure 11 , Figure 11 The air flow effect diagram is drawn. The cold air flows vertically downward through the gap between each two drainage membranes, exchanges heat with the condenser tube and condensed water, removes heat, and causes the gaseous refrigerant to change phase. By utilizing the first condenser tube 1 and the second condenser tube 6 at an inclined angle in the condenser tube group, the gaseous refrigerant is converted into liquid refrigerant and flows downward quickly and promptly; space is promptly freed up in the first condenser tube 1 and the second condenser tube 6 to retain a larger heat exchange area, so that more gaseous refrigerant completes phase change, thereby improving efficiency.
[0069] For further information, see Figure 11 When the condensed water is drained on the first pipe body 2, since the first condenser tube 1 and the second condenser tube 6 are inclined at different angles, the water can also at least partially flow to the first bend 3, thereby increasing the heat exchange area and solving the problem that heat exchange cannot be carried out at the current bend.
[0070] For further information, see Figure 10 、 Figure 11 and Figure 12 , using the condenser tube group at an inclined angle to achieve a wider air inlet 23; The buffer space 19 is used to achieve a more uniform distribution of cold air. In addition, the cold air can enter the gaps between each water film in the condenser tube group at a more uniform speed after entering the buffer space 19 through the air inlet 23.
[0071] Example 5 The refrigeration system of the present invention includes all the solutions of the falling film condenser of Example 2 or Example 3, and adopts the condensation method of Example 4 to realize the refrigeration system of the present invention, which at least includes: the first liquid condenser tube 11 and the second liquid condenser tube 12 in the falling film condenser are connected to an expansion valve, the expansion valve is connected to an evaporator, the evaporator is connected to a compressor, and the compressor is connected to the first gaseous condenser tube 9 and the second gaseous condenser tube 10 of the condenser.
[0072] The advantages brought by embodiments 1 to 5 of the present invention are: The condenser tube group of the present invention and the falling film condenser, condensation method and refrigeration system using the same are such that the first condenser tube 1 and the second condenser tube 6 of the condenser tube group are respectively at an inclined angle, so that the entire condenser tube group is at an inclined angle, so that during application, the air inlet surface is increased, thereby solving the contradiction between the size of the air inlet and the volume of the condenser in the prior art.
[0073] The condenser tube assembly of the present invention and the falling film condenser, condensation method, and refrigeration system using the same, by changing the position of the air inlet 23 to be located on the side of the condenser main box 13, and more importantly, above the condensation bin 15, and by changing the air inlet direction to enter from above, the air inlet and water distribution flow directions are the same, thereby preventing water from being blown away from the surface of the condenser tube and preventing the condenser tube from being exposed. The condenser tube group of the present invention and the falling film condenser, condensation method and refrigeration system using the same, since the air inlet 23 is arranged on the side, solves the problems of large air intake volume and volume, and also plays a role in being away from the fan, making it difficult to suck in the hot air from the fan, thereby solving the problem of the current technical solution easily sucking back the hot air from the fan.
[0074] The condenser tube group of the present invention and the falling film condenser, condensation method and refrigeration system using the same realize upper air intake because the position of the air inlet 23 is higher than the condenser tube group; and the condensation bin 15 also has a buffer space 19, so that the wind can pass evenly between the water films of the condenser tube group, thereby solving the problems in the prior art that the side air intake will blow away the water on the surface of the condenser tube, and the existing condenser tube will block the air intake.
[0075] The condenser tube group of the present invention and the falling film condenser, condensation method and refrigeration system using the same have the same air inlet direction and water flow direction, and the wind passes through the water films. While taking away heat, the water on the surface of the condenser tube will not be blown away. This solves the problem in the prior art that if any part of the surface of the condenser tube is not covered with water, then the entire larger area below that position will not be covered with water, seriously affecting the condensation effect.
[0076] The condenser tube group of the present invention and the falling film condenser, condensation method and refrigeration system using the same have the same air inlet direction and water flow direction, and the wind passes through the water films, which will not blow away the water on the surface of the condenser tube. On the one hand, it is conducive to taking away heat, and on the other hand, the wind is more evenly distributed, which solves the problems that water will block the air inlet, wind will blow away the water on the surface of the condenser tube, and water will cause uneven wind distribution; it also solves the problem in the prior art that the wind first contacts the filler and then heats up.
[0077] The condenser tube group of the present invention and the falling film condenser, condensation method and refrigeration system using the condenser tube group, the incoming air first contacts the first condenser tube 1 and the second condenser tube 6, which more effectively improves the efficiency. In addition, the condenser tube group of the present invention is at an inclined angle, and the first pipe body 2 and the second pipe body 7 are arranged vertically, and the flow directions of water and wind are the same. Therefore, on the one hand, the problem of temperature rise caused by the filler is solved. On the other hand, the present invention can do without the filler 18 and can delete the filler 18, which changes the traditional prejudice in the industry. In the absence of filler, the wind guidance is still very good, and the cost is low, while the efficiency can be improved.
[0078] The condenser tube group of the present invention and the falling film condenser, condensation method and refrigeration system using the condenser tube group, the first condenser tube 1 and the second condenser tube 6 in the condenser tube group of the present invention are at an inclined angle, and the first condenser tube 1 and the second condenser tube 6 form a vertical row under the inclined angle, and the liquid refrigerant in the first condenser tube 1 and the second condenser tube 6 can quickly flow into the first liquid condenser tube 11 and the second liquid condensing refrigerant tube 12, leaving a larger contact area for the first condenser tube 1 and the second condenser tube 6 to perform heat exchange in real time, so that the phase change of the refrigerant is more efficient and more sufficient. Moreover, even if the power of the refrigeration unit is turned on a little lower, the refrigeration capacity of the evaporator will not be affected due to the improvement of the heat exchange capacity, thereby saving the condensation cost and greatly improving the efficiency. Because the heat exchange area is large, the phase change conversion rate of the refrigerant is higher, and the efficiency of the refrigeration unit can be the same or similar to the original high power when the power is low.
[0079] The condenser tube group of the present invention and the falling film condenser, condensation method and refrigeration system using the condenser tube group are at an inclined angle, so the liquid refrigerant in all the first condenser tubes 1 and the second condenser tubes 6 will flow forward better, which solves the current problems of liquid refrigerant occupying space in the condenser tubes and low heat exchange efficiency, and at the same time provides a large amount of refrigerant for the evaporator, bringing about the effect of one plus one being greater than two.
[0080] The condenser tube assembly of the present invention and the falling film condenser, condensation method, and refrigeration system using the same enable the liquid refrigerant in the first condenser tube 1 and the second condenser tube 6 to slowly flow forward without the compressor even after the refrigeration unit is shut down, ensuring that only gaseous refrigerant remains in the first condenser tube 1 and the second condenser tube 6. This also facilitates the next startup of the unit, as more liquid refrigerant is immediately supplied to the evaporator. This solves the problem in current refrigeration equipment where a large amount of liquid refrigerant remains in the condenser tubes until the system is shut down, while some gaseous refrigerant is drawn into the evaporator.
[0081] The condenser tube group of the present invention and the falling film condenser, condensation method and refrigeration system using the same are such that, since the first condenser tube 1 and the second condenser tube 6 are always in an inclined state and the position of the inlet end 4 is higher than the outlet end 5, it is not easy for liquid refrigerant to remain in the condenser tubes whether the refrigeration unit is in operation or in a shutdown state, and the serious liquid refrigerant residue problem caused by the current vertical arrangement of the condenser tubes is solved.
[0082] The condenser tube group of the present invention and the falling film condenser, condensation method and refrigeration system using the same, because the first condenser tube 1 and the second condenser tube 6 are always in an inclined state, the liquid refrigerant can be discharged in real time, and even if the condenser tube is bent, liquid refrigerant is not easily accumulated; compared with the existing technology, the heat exchange area is increased and the efficiency is high; it solves the current problem that the liquid refrigerant is deposited more due to the high and low inclination angles or slight bends of the condenser tube, which greatly reduces the heat exchange area and causes the cooling capacity of the refrigeration unit to be not proportional to the power. The present invention greatly improves the heat transfer efficiency compared with the existing technology under the conditions of equal volume and opening the same power.
[0083] The condenser tube group of the present invention and the falling film condenser, condensation method and refrigeration system using the same, since the first condenser tube 1 and the second condenser tube 6 are always in an inclined state, the liquid refrigerant can flow smoothly, which solves the current problem that the ends of the condenser tubes are narrowed, further causing at least a portion of the liquid refrigerant in each condenser tube to be stored inside and unable to come out.
[0084] The condenser tube group of the present invention and the falling film condenser, condensation method and refrigeration system using the condenser tube group, since the first condenser tube 1 and the second condenser tube 6 are arranged at intervals; and the inlet end 4 of the first condenser tube 1 and the inlet end 4 of the second condenser tube 6 are in opposite directions; the outlet end 5 of the first condenser tube 1 and the outlet end 5 of the second condenser tube 6 are in opposite directions; therefore, the present invention solves the problem that when the number of arranged condenser tubes is too large, the ends of the condenser tubes can achieve good sealing without being narrowed.
[0085] The condenser tube group of the present invention and the falling film condenser, condensation method and refrigeration system using the same, by installing the condenser tube group above the condensation bin 15 and combining the design of the air inlet 23 and the buffer space 19, can allow air to enter from above, the wind first contacts the condenser tube, and the incoming air flows along the gaps in the water film, thereby solving the problem of not blowing away the water on the surface of the condenser tube and exposing the condenser tube, and solving the problem of the water film in the prior art blocking the air intake, thereby overcoming the existing contradictory problems.
[0086] The condenser tube group of the present invention and the falling film condenser, condensation method and refrigeration system using the same can discharge the liquid refrigerant in time, thereby solving the current problem that the liquid refrigerant occupies the space of the condenser tube, reduces the area of the condenser tube for heat exchange, wastes the power of the compressor and condenser, and reduces the condensation amount. It also solves the current problem that condensation needs to be achieved by increasing the amount of cold water and lowering the cold water temperature.
