Description

Technical Field

[0001] This invention relates to the field of evaporation and condensation technology, and more specifically, to an energy-saving, antifreeze, and anti-scaling evaporation and condensation device. Background Technology

[0002] Evaporative condensers are the main heat exchange equipment in refrigeration systems. Their working principle is as follows: the superheated and high-pressure refrigerant gas discharged from the compressor in the refrigeration system passes through the condenser coils in the evaporative condenser, allowing the high-temperature gaseous refrigerant to exchange heat with the sprayed water and air outside the coils.

[0003] However, in winter, as the ambient temperature decreases, the load on the refrigeration system also decreases. Therefore, the evaporative condenser does not need to run continuously, because the low temperature itself helps with condensation. In this case, the spray system is usually turned off, and the basic function of the condenser can be maintained by relying solely on air cooling.

[0004] When an evaporative condenser is working continuously, the steam it generates heats the spray water, causing the water in the tank to heat up as it circulates. However, under low-temperature conditions, after the spray system stops working, the water in the tank is prone to freezing due to the low ambient temperature. This can prevent the spray system from starting up again when the condenser is restarted, thus causing the condenser to malfunction. Summary of the Invention

[0005] This invention provides an energy-saving, antifreeze, and anti-scaling evaporative condensation device, which solves the technical problem in related technologies where, under low-temperature conditions, the water in the tank freezes due to the influence of ambient temperature after the condenser stops working, causing the subsequent condenser to malfunction.

[0006] This invention provides an energy-saving, antifreeze, and anti-scaling evaporative condensation device, including a housing and a condenser coil, a water tank, and a spray pipe fixedly connected inside it. The housing has air inlet windows and air outlet windows on both sides and the top, respectively. An air outlet unit is provided at the top of the air outlet window. The air outlet unit includes a motor fixedly connected to the top of the air outlet window through a grille, and the output shaft of the motor passes through the interior of the air outlet window and is fixedly connected to an exhaust fan. The interior of the enclosure is equipped with an insulation component to reduce heat loss. The insulation component includes an air inlet closing unit and an air outlet closing unit located inside the air inlet and air outlet windows, and also includes a water storage unit located inside the enclosure for controlling the opening and closing of the air inlet closing unit.

[0007] As a further optimization of the present invention, the water storage unit includes a water storage tray disposed on both sides inside the tank, and a sliding plate is fixedly connected to the bottom of the water storage tray. A slider adapted to a sliding groove opened on the inner wall of the tank is fixedly connected to the surface of the sliding plate, and the bottom of the slider is connected to the sliding groove by a first spring. A push plate is rotatably connected to the bottom of the sliding plate through a first rotating shaft.

[0008] As a further optimization of the present invention, the air inlet closing unit includes a sealing plate rotatably connected to the inside of the air inlet window via a second rotating shaft. One end of the upper sealing plate is fixedly connected to a force-bearing plate, and the end of the second rotating shaft is fixedly connected to a first gear. The inside of the air inlet window is slidably connected to a rack that meshes with the first gear, and the bottom of the rack is connected to the air inlet window via a second spring.

[0009] As a further optimization of the present invention, the exhaust closure unit includes a solid part fixedly connected inside the exhaust window, and the surface of the solid part has ventilation openings diagonally. A storage groove is provided on one side of the solid part. The output shaft surface of the motor is movably connected to a closing blade through a damping bearing, and the closing blade and the damping bearing are connected by a coil spring.

[0010] As a further optimization of the present invention, the interior of the housing is provided with a descaling component for removing scale adhering to the surface of the condenser coil. The descaling component includes a cleaning unit disposed outside the condenser coil and an intermittent drive unit disposed at the bottom of the housing for controlling the operation of the cleaning unit.

[0011] As a further optimization of the present invention, the cleaning unit includes a second gear and a rotating ring that are movably sleeved on both sides of the straight pipe section of the condenser coil. Multiple second gears are connected in series through toothed chains, and a cleaning seat is fixedly connected between the second gear and the rotating ring.

[0012] As a further optimization of the present invention, the intermittent drive unit includes a bracket fixedly connected to the bottom of the housing, and a water storage cylinder is rotatably connected to the upper end of the bracket via a third rotating shaft. A pull rod is rotatably connected between the upper end of the water storage cylinder and the toothed chain via a fourth rotating shaft. A counterweight is provided at the lower end of the water storage cylinder, and a drain pipe for injecting water into the water storage cylinder is fixedly connected to one side of the water storage pan.

[0013] As a further optimization of the present invention, the cleaning seat has a flow guide port on its side and a water storage chamber inside the cleaning seat. Cleaning brushes are arranged alternately inside the water storage chamber, and nozzles connected to the water storage chamber are distributed in a ring at the bottom of the cleaning seat.

[0014] As a further optimization of the present invention, the interior of the box is provided with a heating component for heating the water inside the water tank. The heating component includes a folding airbag fixedly connected to the interior of the box, and the upper and lower ends of the folding airbag are respectively fixedly connected with an air intake pipe and an air exhaust pipe. Both the air intake pipe and the air exhaust pipe are provided with a one-way valve. One end of the folding airbag is fixedly connected to the toothed chain by a traction rope, and a third spring is fixedly connected inside the folding airbag.

[0015] As a further optimization of the present invention, a water pump is fixedly connected to one side of the box body, and the water pump is connected to the water tank and the spray pipe respectively through the water guide pipe. An air inlet pipe and a liquid outlet pipe are fixedly connected to one side of the box body, and both the air inlet pipe and the liquid outlet pipe penetrate into the interior of the box body and are fixedly connected to a distribution pipe. The two distribution pipes are fixedly connected to the upper and lower ends of the condenser coil respectively.

[0016] The beneficial effects of this invention are as follows: 1. The energy-saving, antifreeze, and anti-scaling evaporative condenser of the present invention controls the opening and closing of the air inlet and exhaust windows through the working status of the spray system. Under the premise of ensuring stable exhaust during condenser operation, the system seals the housing after the spray system stops working, isolating the entry of external low-temperature air and the discharge of internal high-temperature steam, reducing the rate of temperature drop inside the housing. This makes it less likely for the condenser to freeze inside during short-term shutdown in low-temperature environments, ensuring that subsequent condenser operation is not affected and guaranteeing the stability of condenser operation in low-temperature environments.

[0017] 2. The energy-saving, antifreeze, and anti-scaling evaporative condensation device of the present invention uses the intermittent swinging of the water storage tank to trigger the cleaning unit to work, thereby forming an intermittent cleaning of the surface of the condensing coil. The cleaning seat cleans the scale on the surface of the condensing coil, avoiding the reduction of heat conduction efficiency of the condensing coil due to scale adhesion, thus ensuring the condensation effect. In addition, the repeated swinging of the water storage tank also agitates the water inside the water tank, thereby making the water inside the water tank move and reducing the freezing speed of the water in the water tank.

[0018] 3. The energy-saving, antifreeze, and anti-scaling evaporative condenser of the present invention unfolds by pulling a folding airbag with a traction rope, thereby drawing some of the steam inside the chamber into the folding airbag through the suction pipe. Then, as the toothed chain resets, the folding airbag contracts under the action of the third spring, thereby discharging the drawn-in high-temperature steam into the water tank through the exhaust pipe, thus heating the water inside the water tank and preventing the water in the tank from freezing due to excessively low temperature, ensuring stable operation of the condenser.

[0021] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification.

[0022] like Figures 1 to 6 As shown, an energy-saving antifreeze and anti-scaling evaporative condensation device according to an embodiment of the present invention includes a housing 10 and a condenser coil 11, a water tank 12 and a spray pipe 13 fixedly connected inside it. The housing 10 has air inlet windows 14 and air outlet windows 15 on its two sides and top, respectively. An air outlet unit 16 is provided at the top of the air outlet window 15. The air outlet unit 16 includes a motor 162 fixedly connected to the top of the air outlet window 15 through a grille 161. The output shaft of the motor 162 passes through the interior of the air outlet window 15 and is fixedly connected to an exhaust fan 163. A water pump 17 is fixedly connected to one side of the housing 10, and the water pump 17 is connected to the water tank 12 and the spray pipe 13 respectively through the water guide pipe 18. An air inlet pipe 111 and a drain pipe 112 are fixedly connected to one side of the housing 10, and both the air inlet pipe 111 and the drain pipe 112 penetrate into the interior of the housing 10 and are fixedly connected to the distribution pipe 113. The two distribution pipes 113 are fixedly connected to the upper and lower ends of the condenser coil 11 respectively. The interior of the housing 10 is provided with a heat insulation component 20 to reduce heat loss. The heat insulation component 20 includes an air inlet closing unit 22 and an air outlet closing unit 23 located inside the air inlet window 14 and the air outlet window 15, and also includes a water storage unit 21 located inside the housing 10 for controlling the opening and closing of the air inlet closing unit 22. The water storage unit 21 includes a water storage tray 211 located on both sides inside the housing 10, and a sliding plate 212 is fixedly connected to the bottom of the water storage tray 211. A slider 213 adapted to the sliding groove 214 opened in the inner wall of the housing 10 is fixedly connected to the surface of the sliding plate 212. The bottom of the slider 213 is connected to the sliding groove 214 by a first spring 215. A push plate 217 is rotatably connected to the bottom of the sliding plate 212 by a first rotating shaft 216. The air inlet closing unit 22 includes a sealing plate 222 rotatably connected to the inside of the air inlet window 14 via a second rotating shaft 221. One end of the upper sealing plate 222 is fixedly connected to a force-bearing plate 223. The end of the second rotating shaft 221 is fixedly connected to a first gear 224. A rack 225 that meshes with the first gear 224 is slidably connected inside the air inlet window 14. The bottom of the rack 225 is connected to the air inlet window 14 via a second spring 226. The exhaust closure unit 23 includes a solid part 231 fixedly connected inside the exhaust window 15, and a ventilation part 232 is provided diagonally on the surface of the solid part 231. A storage groove 233 is provided on one side of the solid part 231. A closing blade 235 is movably connected to the surface of the output shaft of the motor 162 through a damping bearing 234, and the closing blade 235 and the damping bearing 234 are connected by a coil spring 236.

[0023] It should be noted that, firstly, the superheated high-pressure refrigerant gas is introduced into the distribution pipe 113 through the inlet pipe 111, and then distributed to the interiors of multiple condensing coils 11 by the distribution pipe 113. After the superheated high-pressure refrigerant gas enters the interior of the condensing coils 11, it conducts heat to the condensing coils 11. At the same time, the water pump 17 operates to introduce water from the water tank 12 into the spray pipe 13 through the water guide pipe 18 and then discharge it from the spray pipe 13. The spray water discharged from the spray pipe 13 is sprayed onto the surface of the condensing coils 11. After the spray water comes into contact with the condensing coils 11, it is heated and evaporates, and the evaporation carries away the heat from the condensing coils 11, thereby providing superheated high-pressure cooling to the interior of the condensing coils 11. The refrigerant gas is cooled down, and the cooled superheated high-pressure refrigerant gas is cooled to form refrigerant liquid which flows into the distribution pipe 113 and is discharged through the drain pipe 112. The water that has not evaporated from the spray falls into the water tank 12 and is pumped by the water pump 17 back to the spray pipe 13 to form a circulating spray. During the evaporation and cooling process, the motor 162 drives the exhaust fan 163 to rotate and discharge the steam inside the box 10 through the exhaust window 15. Meanwhile, the low-temperature air from the outside enters the inside of the box 10 through the air inlet window 14 under the air flow and, together with the spray water, forms a heat exchange with the condenser coil 11, which accelerates the cooling speed of the superheated high-pressure refrigerant gas inside the condenser coil 11. During the spraying process, some of the spray water falls into the water storage tray 211. As the amount of spray water collected inside the water storage tray 211 increases, it is pushed downward by gravity, thereby pushing the slide plate 212 downward. At this time, the slider 213 on the slide plate 212 slides inside the slide groove 214 and compresses the first spring 215. After the slide plate 212 moves downward, it pushes the force plate 223 downward through the push plate 217 at its lower end. As the force plate 223 moves downward after being stressed, it drives the uppermost sealing plate 222 to rotate through the second rotating shaft 221. After the upper sealing plate 222 rotates, it drives the second rotating shaft 221 to rotate. Shaft 221 drives the first gear 224 to rotate, thereby driving the rack 225 to move downward through the first gear 224 at the upper end. During the downward movement of the rack 225, the second spring 226 is compressed, which in turn drives the multiple first gears 224 at the lower end to rotate and drives the remaining sealing plates 222 to rotate, thereby opening the air inlet window 14 to ensure that outside air can enter the interior of the housing 10. During the downward movement of the force plate 223, it also rotates. Therefore, while the push plate 217 applies a pushing force to the force plate 223, it can also rotate synchronously with the force plate 223 through the first rotating shaft 216 to ensure stable pushing of the force plate 223. In addition, when the motor 162 is working, it drives the closing blade 235 to rotate through the output shaft, so that the closing blade 235 rotates from the ventilation part 232 through the receiving groove 233 to the interior of the solid part 231, and drives the coil spring 236 to rewind, thereby connecting the ventilation part 232 with the exhaust window 15, which facilitates the discharge of steam inside the box 10. Since the closing blade 235 is connected to the output shaft of the motor 162 through the damping bearing 234, when the closing blade 235 enters the interior of the receiving groove 233, it is restricted by the solid part 231 and no longer rotates with the output shaft of the motor 162. The output shaft of the motor 162 continues to rotate under the action of the damping bearing 234, and the closing blade 235 will drive the coil spring 236 to rewind during the closing process. When the spray pipe 13 stops spraying, as the water accumulated inside the water storage pan 211 is discharged, the first spring 215 pushes the slider 213 to move upward inside the slide groove 214, thereby driving the slide plate 212 and the push plate 217 to reset and release the force on the force plate 223. Then, the second spring 226 resets and pushes the rack 225 to move upward. After the rack 225 moves upward, it drives the first gear 224 and the second rotating shaft 221 to rotate, thereby driving the sealing plate 222 to reset and block the air inlet window 14. At the same time, the motor 162 also stops working. Under the action of the coil spring 236, it drives the closing blade 235 to reset to the ventilation part 232, thereby blocking the exhaust window 15 as well. This makes the box 10 form a closed state, isolating the entry of external low-temperature air and the discharge of internal high-temperature steam, reducing the rate of temperature drop inside the box 10. This makes it less likely for the condenser to freeze inside during a short-term shutdown in a low-temperature environment, ensuring that the subsequent operation of the condenser is not affected and guaranteeing the stability of the condenser in a low-temperature environment.

[0024] like Figure 2 , Figure 5 and Figure 7 As shown, the interior of the housing 10 is provided with a descaling assembly 30 for removing scale from the surface of the condenser coil 11. The descaling assembly 30 includes a cleaning unit 31 disposed outside the condenser coil 11 and an intermittent drive unit 32 disposed at the bottom of the housing 10 for controlling the operation of the cleaning unit 31. The cleaning unit 31 includes a second gear 311 and a rotating ring 313 that are movably sleeved on both sides of the straight section of the condenser coil 11. Multiple second gears 311 are connected in series by a toothed chain 312. A cleaning seat 314 is fixedly connected between the second gear 311 and the rotating ring 313. The intermittent drive unit 32 includes a bracket 321 fixedly connected to the bottom of the housing 10, and a water storage cylinder 323 is rotatably connected to the upper end of the bracket 321 via a third rotating shaft 322. A pull rod 325 is rotatably connected between the upper end of the water storage cylinder 323 and the toothed chain 312 via a fourth rotating shaft 324. A counterweight block 326 is provided at the lower end of the water storage cylinder 323. A drain pipe 327 for injecting water into the water storage cylinder 323 is fixedly connected to one side of the water storage pan 211.

[0025] It should be noted that after the water storage pan 211 is filled with water, as the water level increases, the spray water will be discharged through the drain pipe 327 and enter the water storage cylinder 323. The water storage cylinder 323 is mounted on the bracket 321 via a third pivot 322 at two-thirds of its length. A counterweight 326 is installed at one-third of the end, causing its weight to be greater than that of the other end, resulting in it falling to the bottom of the water tank 12. When the water storage cylinder 323 is full of water, the weight at the two-thirds end is greater than the weight of the other end. One end of the counterweight 326 causes the end of the water tank 323, which occupies two-thirds of the space, to fall down and pull the toothed chain 312 through the pull rod 325. The toothed chain 312 rotates, and after the toothed chain 312 rotates, it drives the second gear 311 to rotate. The second gear 311 and the rotating ring 313 drive the cleaning seat 314 to rotate. The cleaning seat 314 cleans the scale on the surface of the condenser coil 11, preventing scale from adhering and reducing the heat transfer efficiency of the condenser coil 11, thereby ensuring the condensation effect. Finally, after the water inside the water tank 323 is discharged, the water tank 323 is reset under the action of the counterweight 326. Then, the pull rod 325 drives the gear chain 312 to rotate, which in turn drives the second gear 311 to drive the cleaning seat 314 to rotate, and clean the surface of the condenser coil 11 again. After the water tank 323 is filled with water again, the cleaning unit 31 is triggered to work, forming an intermittent cleaning of the surface of the condenser coil 11. The repeated swinging of the water tank 323 will also agitate the water inside the water tank 12, thereby making the water inside the water tank 12 move and reducing the freezing speed of the water in the water tank 12.

[0026] like Figure 8 As shown, the cleaning seat 314 has a flow guide port 3141 on its side and a water storage chamber 3143 inside the cleaning seat 314. Cleaning brushes 3142 are arranged alternately inside the water storage chamber 3143 for cleaning the surface of the condenser coil 11 to remove the scale attached to its surface. The bottom of the cleaning seat 314 has nozzles 3144 that are connected to the water storage chamber 3143 in a ring.

[0027] It should be noted that when the spray water is sprayed onto the surface of the condenser coil 11, the upper part of the condenser coil 11 is easily in contact with the dispersed water, while the lower part is blocked, causing the originally dispersed water to gather together again, which reduces the evaporation efficiency of the lower part. Therefore, a guide port 3141 is opened on the side of the cleaning seat 314. When the spray water falls on the condenser coil 11, it flows along the surface of the condenser coil 11 and enters the water storage chamber 3143 through the guide port 3141. Then it is dispersed and discharged again by the nozzle 3144, so that the sprayed water forms a thin water film that can evaporate in time, thereby improving the evaporation efficiency of the condenser.

[0028] like Figure 9 and Figure 10 As shown, the interior of the housing 10 is equipped with a heating component 40 for heating the water inside the water tank 12. The heating component 40 includes a folding airbag 41 fixedly connected to the interior of the housing 10. The upper and lower ends of the folding airbag 41 are respectively fixedly connected to an air intake pipe 42 and an exhaust pipe 43. Both the air intake pipe 42 and the exhaust pipe 43 are equipped with one-way valves. One end of the folding airbag 41 is fixedly connected to the toothed chain 312 via a traction rope 44. A third spring 45 is fixedly connected inside the folding airbag 41.

[0029] It should be noted that when the toothed chain 312 is pulled by the pull rod 325 and rotates, the toothed chain 312 pulls the folding airbag 41 to unfold through the traction rope 44, thereby drawing some of the steam inside the box 10 into the folding airbag 41 through the suction pipe 42. Then, as the toothed chain 312 returns to its original position, the folding airbag 41 is driven to contract under the action of the third spring 45, thereby discharging the inhaled high-temperature steam into the water tank 12 through the exhaust pipe 43, thereby heating the water inside the water tank 12 and preventing the water in the water tank 12 from freezing due to excessively low temperature, thus ensuring the stable operation of the condenser.

The specific implementation methods described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the embodiments described above, all of which are within the protection scope of the embodiments described above.
