Description

Technical Field

[0001] This invention belongs to the field of heat exchange technology, specifically relating to a peak closed-loop condensation cooling device that combines water-saving, energy-saving, and defogging functions. Background Technology

[0002] Evaporative condensers, as highly efficient heat exchange devices, operate primarily on the principle of heat absorption through the evaporation of sprayed water and heat transfer through convection of air. The top of the evaporative condenser is equipped with a spray system. A circulating water pump delivers water from a tank to this system, where the water, under gravity, is sprayed through nozzles onto the outer surface of the coils, forming a water film. A fan is located on the top or side of the evaporative condenser. When the fan operates, it draws outside air into the equipment, where it exchanges heat with the water film on the outer surface of the coils. Some of the water in the film evaporates into water vapor, absorbing heat from the medium inside the coils. The resulting water vapor is then expelled from the equipment with the air. This heat exchange process involves the significant consumption of sprayed water.

[0003] When the ambient temperature is low, the nearly saturated, hot and humid air at the outlet of the evaporative condenser comes into contact with the low-temperature ambient air, causing condensation and precipitation of small water droplets, resulting in a white fog phenomenon.

[0004] The formation of white fog has the following negative effects: 1) Affects the aesthetics of the environment: A large amount of white fog will make the environment around the equipment hazy, creating visual pollution. This effect is more obvious, especially in cities or areas with high requirements for the aesthetics of the environment.

[0005] 2) Altering local weather: The white fog generated by clustered cooling towers or evaporative condensers significantly increases the relative humidity and temperature of the local air, causing irreversible negative impacts on the ecological environment.

[0006] 3) Causes equipment corrosion: The white fog contains certain acidic substances and salts, which adhere to the surface of surrounding equipment and buildings, causing corrosion over time and shortening the service life of equipment and buildings.

[0007] 4) Safety hazards: In cold weather, the moisture in the fog will freeze on the ground or roads, making the ground slippery and increasing the risk of pedestrians falling and vehicles skidding.

[0008] 5) Causes water waste: The white mist from the cooling tower is actually the emission of water vapor, which means that a large amount of water is emitted into the atmosphere in the form of steam, resulting in the waste of water resources.

[0009] To address the white mist in evaporative condenser coolers, existing technologies typically employ the following two measures: 1) Heating method: A pre-cooling heating device is added to the top of the equipment to heat the discharged humid air, increasing its temperature and reducing its relative humidity. When it comes into contact with the low-temperature ambient air, it is less likely to condense and produce white mist. However, during this heating process, the moisture content of the humid air at the outlet of the evaporative condenser is not reduced, and water saving is not achieved.

[0010] 2) Condensation method: Add an anti-fog module inside the equipment to condense part of the exhaust hot and humid air, and recycle it. The condensed hot and humid air is mixed with the cold air after heat exchange, which reduces the moisture content, relative humidity and temperature. It is then discharged into the atmosphere to come into contact with the low temperature air in the environment, thereby reducing the formation of white fog.

[0011] However, both heating and condensation methods require the addition of corresponding components inside the equipment, which can lead to insufficient fan head and air volume. Therefore, when designing an evaporative condenser cooler, the only option is to increase the power of the fan, resulting in high energy consumption during equipment operation. Summary of the Invention

[0012] This invention provides a peak closed-loop condensing and cooling device that combines water-saving, energy-saving, and defogging functions, in order to solve the problems of white fog pollution, water waste, and high operating energy consumption of existing evaporative condensing coolers mentioned in the background art.

[0013] The technical solution adopted in this invention is: a peak closed-loop condensation cooling device with water-saving, energy-saving and defogging functions, including a box body, and a mixing chamber in the upper part of the inner cavity of the box body; The inner cavity of the box is connected in sequence with an anti-fogging module, a drag-reducing louver and a water distribution device. The anti-fogging module divides the lower inner cavity of the box into a first cavity and a second cavity. The anti-fogging module has a cold air channel and a hot air channel that are respectively connected to the mixing chamber. The first cavity is connected to the cold air channel and the second cavity is connected to the hot air channel. An evaporator coil is installed in the second cavity near the side wall of the box, and water dripping from the water distribution device can fall onto the heat exchange wall of the evaporator coil. It also includes a peaking device, which is located inside the chamber of the tank and directly above the water distribution device; The first cavity, the second cavity, and the spike device are each equipped with an openable and closable ventilation assembly near the side wall of the housing. When each ventilation assembly is activated: Air enters the mixing chamber through the cold air passage of the first cavity and the defogging module; After the air exchanges heat through the evaporator coil along the second cavity, it enters the mixing chamber through the hot air channel of the defogging module. With the drag-reducing louvers open, part of the heat-exchanged air enters the mixing chamber through the drag-reducing louvers. Air enters the inner cavity along the side wall of the chamber and then enters the mixing chamber after passing through the spike device.

[0014] The system also includes a water supply system, which includes a circulating water tank installed at the bottom of the tank. A circulating water pump is installed on the circulating water tank, and the output end of the circulating water pump is connected to a water inlet pipe. The water inlet pipe is divided into two lines. One line is connected to a spray device above the peak device, which is configured to spray water onto the peak device. The other line is connected to a water distribution device, which is configured to sprinkle water droplets onto the evaporation coil below. Each of the two water inlet pipes is equipped with a regulating valve.

[0015] A sedimentation tank is installed at the bottom of the circulating water tank.

[0016] A condensate recovery tray is provided at the bottom of the box in the second cavity, and the condensate recovery tray is connected to the circulating water tank.

[0017] The evaporator coil has a medium inlet and a medium outlet extending to the outside of the housing at both ends.

[0018] A water collector is installed above the drag-reducing louvers.

[0019] The defogging module has a rhomboid cross-section, with a partition connected below it, and the end of the partition is fixed to the bottom of the box.

[0020] An exhaust fan is installed on the top of the enclosure.

[0021] The openable and closable ventilation components are as follows: The new cold air louvers are located on the side wall of the housing near the first cavity; The anti-freeze louvers are located on the side wall of the box near the second cavity; The spike louvers are located on the side wall of the enclosure near the spike device. Among them, the three types of louvers and the drag-reducing louvers are any one of manual louvers, pneumatic louvers, and electric louvers.

[0022] The beneficial effects of this invention are as follows: 1. This invention has a peak-shaving function: the peak-shaving device can be activated under high-temperature conditions in summer, effectively enhancing the system's cooling capacity, ensuring stable operation of the equipment under high load conditions, and guaranteeing the smooth operation of the equipment during the summer.

[0023] 2. This invention has a defogging function: the hot and humid air at the outlet of the evaporator coil is partially condensed by the diamond-shaped defogging packing. The condensed hot and humid air is mixed with the cold air after heat exchange, and its moisture content, relative humidity and temperature are reduced. Then it is discharged into the atmosphere and comes into contact with the low temperature air in the environment, so it is not easy to produce white fog.

[0024] 3. This invention is more water-saving: On the one hand, the peak device is shut down during the off-peak season and the peak louvers are closed. At this time, no spray water and air pass through the peak device, and there is no evaporation of spray water in the peak device; on the other hand, in the defogging mode, the hot and humid air at the outlet of the evaporative coil is partially condensed and recycled through the diamond-shaped defogging packing, thereby achieving the purpose of water saving.

[0025] 4. This invention is more energy-efficient: On the one hand, during off-peak seasons, the ambient temperature is low, and the heat exchange demand can be met by the evaporative coil alone. At this time, the peak-load device is shut down and the peak-load louvers are closed, so no air passes through the peak-load device, avoiding the waste of air volume and reducing the operating energy consumption of the fan. On the other hand, during non-fogging seasons, the drag-reducing louvers are fully open, and their own air resistance is low. Some of the hot and humid air at the outlet of the evaporative condenser is discharged from the equipment through the drag-reducing louvers, resulting in a small overall pressure drop and thus achieving the purpose of energy saving.

[0026] 5. This invention has a self-antifreeze function. When all louvers are closed, the exhaust fan will not generate suction, and the medium in the evaporator coil retains heat, forming a warm room inside the equipment, which is beneficial for preventing the equipment from freezing and ensuring that the equipment can survive the winter smoothly.

[0027] 6. When the peak-load device of the present invention is shut down during non-peak seasons, there is ample time for its inspection, cleaning and maintenance, and the impact on normal production operation is minimal, thus avoiding equipment downtime problems.

[0028] 7. The present invention has high heat exchange efficiency. By adjusting the opening degree of the peak louvers and the anti-freeze louvers, the required air volume of the peak device and the evaporator coil is reasonably distributed, thereby achieving the best heat exchange effect.

[0029] 8. The submerged sedimentation tank provides a dirt accumulation area for convenient centralized sewage discharge, reduces the operating weight of the equipment, and increases the liquid level at the suction inlet of the circulating water pump, reducing the risk of pump cavitation.

[0030] 9. This invention can be used for multiple purposes, making reasonable use of different functions in different application scenarios, eliminating waste, and achieving resource optimization and integration. Attached Figure Description

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] As shown in the figure, a peak closed-loop condensation cooling device with water-saving, energy-saving and defogging functions includes a box 1. The upper part of the inner cavity of the box 1 has a mixing chamber 101. An exhaust fan 9 is installed on the top of the box 1. When the exhaust fan 9 is working, the air in the mixing chamber 101 can be drawn upward and discharged upward from the exhaust fan 9. The inner cavity of the housing 1 is sequentially connected to an anti-fogging module 10, a drag-reducing louver 15, and a water distribution device 19. A water collector 14 is located above the drag-reducing louver 15. The anti-fogging module 10 divides the lower inner cavity of the housing 1 into a first cavity 102 and a second cavity 103. The anti-fogging module 10 has a cold air channel and a hot air channel respectively connected to the mixing chamber 101, with the first cavity 102 connected to the cold air channel and the second cavity 103 connected to the hot air channel. Specifically, the anti-fogging module 10 has a rhomboid cross-section. A partition 12 is connected below, and the end of the partition 12 is fixed to the bottom of the box 1. The defogging module 10 extends from one end to the other inside the box 1. Its internal cold air channel and hot air channel are connected at the position of the upper mixing chamber 101, while the cold air channel and hot air channel are separated by the partition 12 below. The defogging module 10 is specifically a diamond-shaped defogging filler, which is made of PVC, fiberglass, aluminum alloy or stainless steel, etc. Its internal structure and principle are conventional settings in the existing technology, and will not be described in detail here. An evaporator coil 18 is installed in the second cavity 103 near the side wall of the housing 1. Water dripping from the water distribution device 19 can fall onto the heat exchange wall of the evaporator coil 18. The two ends of the evaporator coil 18 are respectively provided with a medium inlet 6 and a medium outlet 5 extending to the outside of the housing 1. The evaporator coil 18 is used to carry the medium to be cooled. Through the combined action of sprayed water and circulating air, a highly efficient condensation and heat exchange process is achieved. Specifically, the structure of the heat exchange components inside the evaporator coil 18 is a tubular, plate, tube-fin, or plate-fin structure. It also includes a peaking device 20, which is disposed inside the housing 1 and located directly above the water distribution device 19. The first cavity 102, the second cavity 103, and the spike device 20 are each equipped with an openable and closable ventilation component near the side wall of the housing 1. When each ventilation component is activated: Air enters the mixing chamber 101 through the cold air passage of the first cavity 102 and the defogging module 10; After the air exchanges heat through the evaporator coil 18 along the second cavity 103, it enters the mixing chamber 101 through the hot air channel of the defogging module 10, and when the drag-reducing louver 15 is open, part of the heat-exchanged air enters the mixing chamber 101 through the drag-reducing louver 15. Air enters the inner cavity along the side wall of the housing 1, and enters the mixing chamber 101 after passing through the spike device 20; Specifically, the openable and closable ventilation components are as follows: The new cold air louver 11 is located on the side wall of the housing 1 near the first cavity 102; Anti-freeze louvers 3 are located on the side wall of the housing 1 near the second cavity 103; The spike louver 2 is located on the side wall of the housing 1 near the spike device 20; Among them, the above three louvers and the drag-reducing louver 15 are any one of manual louvers, pneumatic louvers, and electric louvers.

[0035] The system also includes a water supply system, which includes a circulating water tank 17 installed at the bottom of the housing 1. A circulating water pump 16 is installed on the circulating water tank 17. The output end of the circulating water pump 16 is connected to a water inlet pipe 8. The water inlet pipe 8 is divided into two paths. One path is connected to a spray device located above the peak device 20 (wherein, the spray device is a combination structure of a water distribution plate above the peak device 20 and a gravity water distribution nozzle), which is used to spray water onto the peak device 20. The other path is connected to a water distribution device 19, which is used to sprinkle water droplets onto the evaporation coil 18 below. Each of the two water inlet pipes 8 is equipped with a regulating valve. In this example, the regulating valve of the water inlet pipe 8 connected to the spray device is regulating valve 7, and the regulating valve of the water inlet pipe 8 connected to the water distribution device 19 is regulating valve 21. The above-mentioned spray device and water distribution device 19 are conventional technologies used in heat exchange equipment in the prior art, and will not be described in detail here.

[0036] A sedimentation tank 4 is provided at the bottom of the circulating water tank 17. The sedimentation tank 4 is designed as a submerged structure. Specifically, a support frame is installed below the tank body 1, and the circulating water tank 17, the circulating water pump 16 and the sedimentation tank 4 are all located within the support frame.

[0037] The bottom of the box 1 in the second cavity 103 is provided with a condensate recovery tray 13, which is connected to the circulating water tank 17. It is used to collect the condensed water in a centralized manner and introduce it into the circulating water tank 17 to achieve water saving effect.

[0038] Now combined Figure 1 , Figure 2The energy-saving principle of the summer peak operation mode of this invention is explained as follows: During the summer peak operation mode, the peak louver 2, antifreeze louver 3, and drag-reducing louver 15 are open, while the fresh air louver 11 is closed; regulating valve 7 is open, and regulating valve 21 is closed. Under the action of the induced draft fan 9, the ambient air enters the peak device 20 through the peak louver 2 to cool the spray water. The cooled spray water falls to the water distribution device 19 of the evaporator coil 18 under the action of gravity. After secondary water distribution by the water distribution device 19, it drips onto the heat exchange wall surface of the evaporator coil 18. The lower spray water temperature improves the heat exchange efficiency of the evaporator coil 18, playing a role in peak reduction. At the same time, the ambient air enters the evaporator coil 18 through the antifreeze louver 3 for heat exchange. The humid and hot air after heat exchange then enters the mixing chamber 101 through the hot air channel of the diamond-shaped anti-fog packing, the drag-reducing louver 15, and the water collector 14. Finally, the humid and hot air is discharged into the atmosphere by the induced draft fan 9. During this process, the peak-shaving device 20 cools the spray water, thus reducing the peak temperature; the humid and hot air from the outlet of the evaporator coil 18 is discharged into the atmosphere through the drag-reducing louver 15, which reduces the overall air resistance and saves energy; the humid and hot air from the outlet of the evaporator coil 18 is discharged into the atmosphere through the hot air channel of the diamond-shaped defogging module 10, which collects water.

[0039] Now combined Figure 1 , Figure 3 The water-saving and energy-saving principles of the present invention under the spring and autumn operation mode are explained as follows: During the spring and autumn operation mode, the ambient temperature is low, and the evaporator coil 18 alone can meet the heat exchange requirements. The peak louver 2 is closed, while the antifreeze louver 3 and the drag-reducing louver 15 are open, and the fresh air louver 11 is closed; regulating valve 7 is closed, and regulating valve 21 is open. Under the action of the induced draft fan 9, all ambient air enters the evaporator coil 18 through the antifreeze louver 3 for heat exchange. The humid air after heat exchange then enters the mixing chamber 101 through the hot air channel of the diamond-shaped defogging module 10, the drag-reducing louver 15, and the water collector 14. Finally, the humid air is discharged into the atmosphere by the induced draft fan 9. During this process, a portion of the hot and humid air from the outlet of the evaporator coil 18 is discharged into the atmosphere through the drag-reducing louver 15, which reduces the overall air resistance and saves energy. A portion of the hot and humid air from the outlet of the evaporator coil 18 is discharged into the atmosphere through the hot air channel of the diamond-shaped defogging module 10, which collects water. At the same time, due to the closure of the peak louver 2 and the regulating valve 7, the peak device 20 is in a shutdown state and has no heat exchange task, thus avoiding the waste of a large amount of air and the evaporation consumption of spray water, achieving the purpose of water saving and energy saving.

[0040] Now combined Figure 1 , Figure 4The defogging principle of the present invention under the winter defogging operation mode is explained as follows: In the winter defogging operation mode, the ambient temperature is low, and white fog is easily generated. Peak louver 2 is closed, antifreeze louver 3 is open, drag-reducing louver 15 is closed, and fresh cold air louver 11 is open; regulating valve 1 7 is closed, and regulating valve 2 21 is open. Because the ambient temperature is low, the air volume required for evaporative heat exchange is small, and the fan head of the equipment can meet the heat exchange requirements. At this time, all the hot and humid air at the outlet of the evaporator coil 18 flows through the hot air channel of the diamond-shaped defogging module 10. The excess fan head provides power to introduce fresh cold air from the environment through the fresh cold air louvers 11. The fresh cold air undergoes indirect heat exchange with the hot and humid air in the hot air channel of the diamond-shaped defogging module 10 through the cold air channel. The hot and humid air in the hot air channel of the diamond-shaped defogging module 10 is condensed, and condensate is released. The condensate falls back to the condensate recovery pan 13 and, under the action of gravity, flows back to the circulating water tank 17 for secondary use, thereby achieving the purpose of water saving. The humid air and fresh cold air that have undergone heat exchange through the wall of the diamond-shaped defogging module 10 are mixed in the mixing chamber 101 by the induced draft fan 9. Compared with the original nearly saturated humid air at the outlet of the evaporator coil 18, the mixed humid air has a lower moisture content, lower relative humidity, and lower temperature, and is further away from the 100% relative humidity line. When it is discharged into the atmosphere and comes into contact with the low-temperature ambient air, it is less likely to produce white fog.

[0041] Now combined Figure 1 , Figure 5 The antifreeze mode of this invention is described as follows: In this mode, the peak louvers 2, antifreeze louvers 3, drag-reducing louvers 15, and fresh air louvers 11 are closed; the induced draft fan 9 and circulating water pump 16 are closed, and the spray water in the circulating water tank 17 is drained. The equipment can be disconnected from the system via a bypass, in which case the medium inside the equipment should be drained; the medium can also flow through the evaporator coil 18, and the equipment participates in system operation. Because the relevant louvers are closed, the induced draft fan 9 will not generate suction, and the medium in the evaporator coil 18 retains heat, forming a warm chamber inside the equipment, which is beneficial for antifreeze protection.

[0042] Now combined Figure 4 , Figure 6 A detailed technical description of the condensation recovery and defogging principle of this invention is provided below: The sprayed water evaporates on the heat exchange wall of the evaporator coil 18 and absorbs heat from the medium, causing the air temperature to rise and the relative humidity to increase. The relative humidity of the humid air exiting the evaporator coil 18 approaches 100%. Figure 6The thermodynamic state point of the humid air at the outlet of evaporator coil 18 is point A. Fresh, cool air from the environment enters the casing through the fresh air louver 11. The fresh air and the humid air at the outlet of evaporator coil 18 undergo heat exchange within the diamond-shaped defogging module 10. The humid air at the outlet of evaporator coil 18 continuously cools and condenses along the 100% relative humidity line, releasing condensate to point B. In the diagram, ΔT represents the temperature drop after partial condensation of the humid air at the outlet of evaporator coil 18, and ΔD represents the amount of condensate released after partial condensation, i.e., the secondary water saving. The released low-temperature condensate falls back to the circulating water tank 17 for continued spray circulation. The humid air after heat exchange with the diamond-shaped defogging module 10 mixes with the heated fresh air in the mixing chamber 101, further reducing the relative humidity and temperature. The thermodynamic state point of the mixed air is point C, which is further away from the 100% relative humidity line. Under the action of the induced draft fan 9, the mixed air is discharged into the atmosphere and mixes with the dry and cold ambient air at point N (e.g., the line connecting point C and point N). This mixture is unlikely to intersect with the 100% relative humidity line, thus effectively eliminating white fog. If the humid and hot air at the outlet of the evaporator coil 18 is not condensed and recovered, its thermodynamic state point is as shown at point A. The line connecting point A and point N intersects with the 100% relative humidity line, and area W is the region where white fog is generated. The lower the ambient air temperature and the higher the relative humidity, the easier it is for white fog to form. The condensation recovery technology of this invention can effectively prevent the formation of white fog and recover some of the condensate, achieving the purpose of eliminating white fog and saving water.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
