Description

Technical Field

[0001] The present invention relates to the technical field of evaporative cooling equipment, and in particular to an evaporative cooling integrated air conditioning unit. Background Art

[0002] Evaporative cooling technology uses cold water from natural cooling sources to spray on the packing. The air flowing through the heat exchanger can directly contact the water film on the surface of the packing for heat and moisture exchange, making the water and air contact evenly. The water absorbs heat from the air and evaporates. The air is cooled and enters the communication base station or communication bureau room to cool down the electronic equipment inside. Since the above evaporative cooling technology does not need to compress the evaporated water vapor, it can reduce the operating energy consumption of the air conditioner and achieve the purpose of energy saving of the air conditioner. And using cold water from natural cooling sources as refrigerant is more environmentally friendly than other mechanical refrigeration systems.

[0003] At present, this type of spray-type evaporative cooling air-conditioning unit still has some shortcomings when used in equipment factories or workshops: 1. After the high-temperature fresh air from outside enters the spray, evaporative gas is generated. This part of the evaporative gas has a certain amount of heat. Since the cooled gas will be sucked into the factory by the exhaust fan, most of the evaporative gas will be sucked into the factory together, resulting in a significant reduction in the cooling effect of the air-conditioning unit; 2. The humidity of the cold air after being treated by the spray-type evaporative cooling air-conditioning is relatively high, which can easily cause the equipment in the factory to get damp, so there is a refrigeration safety hazard.

[0004] To this end, the present invention proposes an evaporative cooling integrated air conditioning unit. Summary of the invention

[0005] The purpose of the present invention is to propose an evaporative cooling integrated air conditioning unit in order to solve the problems mentioned in the background technology.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] The evaporative cooling system is characterized in that the evaporative cooling system has a plurality of air intake pipes, the intake pipes of the plurality of air intake pipes are connected to the intake pipes through the air intake pipes and the intake pipes are connected to the intake pipes through the air intake pipes.

[0008] As a further description of the above technical solution:

[0009] The ventilation carrier is a conical structure with evenly distributed air holes formed thereon. The large end of the ventilation carrier faces the drainage tube. The inner peripheral wall of the heat exchange tube is provided with an integrated annular recess, and the diversion holes are located in the annular recess.

[0010] As a further description of the above technical solution:

[0011] The filler plate comprises a ventilation cage and a hydrophobic filler located in the ventilation cage. One end of the ventilation cage is fixedly connected to the outer cone wall of the ventilation carrier plate. The air holes on the ventilation carrier plate are located in the ventilation cage.

[0012] As a further description of the above technical solution:

[0013] The spray part includes a water pipe and a spray plate located at one end of the water pipe. The outer periphery of the spray plate is fixedly connected with a spray head which is axially evenly distributed and whose water outlet is opposite to the hydrophobic filler. The water pipe passes through the middle of the hydrophobic filler and the ventilation carrier and the outer peripheral wall of the drainage tube. The water pipe and the ventilation carrier are rotatably connected.

[0014] As a further description of the above technical solution:

[0015] A positioning sleeve mounted on the outside of the water pipe is fixedly connected to the middle of the ventilation carrier plate. The water vapor evaporation diverter also includes a sealing plate fixedly mounted on the outside of the positioning sleeve. The sealing plate and the positioning sleeve are screwed together. The sealing plate is opposite to the air hole. The drain pipe is tangentially connected to the outer peripheral wall of the annular drainage box.

[0016] As a further description of the above technical solution:

[0017] The base is fixedly connected with a collecting ring which covers the outside of the annular drainage box, and the inner peripheral wall of the collecting ring is provided with an annular groove which is opposite to the drainage pipe.

[0018] As a further description of the above technical solution:

[0019] A rotating shaft is provided through the other end of the drainage tube, and one end of the rotating shaft is fixedly sleeved with a condensation ventilation water lock box located in the drainage tube. The outer peripheral wall of the drainage tube is fixedly connected with an integrated annular expansion drainage box opposite to the outer periphery of the condensation ventilation water lock box, and the outer periphery of the condensation ventilation water lock box is provided with axially evenly distributed drainage holes.

[0020] As a further description of the above technical solution:

[0021] The condensation ventilation lock water box includes a positioning cylinder and a condensation plate. The number of the condensation plates is at least three and they are fixedly sleeved in the positioning cylinder at equal intervals. The rotating shaft passes through the middle of the condensation plate and the two are fixedly connected. The drainage hole is opposite to the space between two adjacent condensation plates. Evenly distributed ventilation pipes are fixedly connected to the plate surface of the condensation plate opposite to one end of the drainage cylinder.

[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0023] 1. In the present invention, by arranging a water vapor evaporation diverter composed of a heat exchange cylinder, a ventilation carrier plate, a filling plate, a spray part and a sealing plate, the hot air fresh wind entering the cold air generated by the spraying treatment, the evaporative vapor and the heat exchange water can be diverted to the maximum extent, which greatly reduces the flow rate of the evaporative vapor mixed into the cold air, makes the temperature of the cold air generated by the spraying lower, and thus greatly improves the effect of the air conditioning refrigeration treatment.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Example 1

[0035] See also Figure 1-5An evaporative cooling integrated air conditioning unit includes a base 1, a drainage tube 2 is fixedly connected to the top of the base 1 through a support plate, a water vapor evaporation diverter 3 is connected to one end of the drainage tube 2, an exhaust pipe 22 near the other end is fixedly connected to the outer peripheral wall of the drainage tube 2, the exhaust pipe 22 is connected to the exhaust fan, and the air outlet of the exhaust fan is connected to the air duct in the factory through a pipeline. The high-temperature fresh air outdoors will enter the water vapor evaporation diverter 3 under the action of the suction force of the exhaust fan, and after cooling treatment, the cold air will enter the drainage tube 2 and finally enter the factory. At the same time, the evaporation steam and cooling water generated by heat exchange will be separated and discharged as much as possible.

[0036] Specifically, the water vapor evaporation diverter 3 includes a heat exchange tube 31, a ventilation carrier 32, a filling plate 33 and a spray part 34. One end of the heat exchange tube 31 is sleeved on the outside of the drainage tube 2 and the two are rotatably connected. A waterproof sealing rubber ring is provided at the rotating connection. The other end of the heat exchange tube 31 is fixedly connected to an air inlet pipe 314, which is the entrance of the outdoor high-temperature fresh air. The ventilation carrier 32 is fixedly sleeved in the heat exchange tube 31 and a filling plate 33 is provided on the side away from the drainage tube 2. The filling plate 33 plays a role of water repellency and air permeability. The spray part 34 is provided on one side of the filling plate 33 in the heat exchange tube 31, which is used to spray water into the filling plate 33, so that the filling plate 33 contains water. When the high-temperature fresh air passes through the filling plate 33, heat exchange will occur. The water in the filling plate 33 evaporates and absorbs heat to form evaporated water. The airflow passing through the filling plate 33 is a low-temperature airflow after cooling.

[0037] Furthermore, an annular drainage box 311 is fixedly sleeved on the outer peripheral wall of the heat exchange tube 31. When the heat exchange tube 31 rotates at a high speed, the ventilation carrier plate 32, the filling plate 33 and the annular drainage box 311 all rotate. The inner peripheral wall of the heat exchange tube 31 is provided with diverter holes 312 which are evenly distributed in the circumference and connected to the inner cavity of the annular drainage box 311. The evenly distributed diverter holes 312 are opposite to the filling plate 33. Therefore, when the dispersed water in the filling plate 33 exchanges heat with the high-temperature fresh air, the heat exchange tube 31 is controlled to rotate at a high speed. At this time, the evaporation steam generated by the internal heat exchange in the filling plate 33 and the water after the heat exchange will accelerate to flow around together, and then enter the annular drainage box 311 through the diverter holes 312, thereby greatly reducing the flow of evaporating water vapor in the cold air, making the temperature of the cold air lower.

[0038] Among them, a drainage pipe 3111 evenly distributed in the circumferential direction is fixedly connected to the outer wall of the annular drainage box 311. When the heat exchange tube 31 drives the annular drainage box 311 to rotate, the cooling water mentioned above will be discharged through the drainage pipe 3111. A valve-controlled steam extraction pipe 3112 is fixedly connected to one side of the annular drainage box 311. A wind valve is connected in series to the valve-controlled steam extraction pipe 3112. When in use, one end of the valve-controlled steam extraction pipe 3112 is connected to a transition sleeve, and the transition sleeve is gap-mounted on the outside of the air inlet pipe 314. Then, a transition tube is rotatably connected to the outside of the transition sleeve. The inner cavity of the transition tube and the transition sleeve are connected. Finally, the outside of the transition tube is connected to the steam extraction fan through a pipeline, so as to discharge part of the evaporated steam in the annular drainage box 311. It should be noted that due to the drainage function of the diverter hole 312, when the diverter hole 312 drains water, water will fill the diverter hole 312, thereby preventing air from entering and exiting the diverter hole 312, and further effectively preventing external gas from entering the heat exchange tube 31 through the drainage pipe 3111 and affecting the cooling effect of the cold air.

[0039] In the present embodiment, the ventilation carrier 32 is a conical structure and is provided with evenly distributed air holes 321. The large end of the ventilation carrier 32 faces the drainage tube 2. This arrangement can increase the coverage area of ​​the water flow on the outer cone of the ventilation carrier 32. The inner wall of the heat exchange tube 31 is provided with an integrated annular recess 313. The diverter hole 312 is located in the annular recess 313. The arrangement of the annular recess 313 facilitates the convergence of the water flow generated by centrifugation and then discharges it through the diverter hole 312, and after convergence, it has the function of reducing the ventilation volume of the diverter hole 312.

[0040] Furthermore, the filler plate 33 includes a ventilation cage 331 and a hydrophobic filler 332 located in the ventilation cage 331. The ventilation cage 331 can be surrounded by a perforated plate to facilitate the passage of water. The hydrophobic filler 332 is made of a porous material with good hydrophobicity, such as non-woven fabric, etc. When the water passes through the hydrophobic filler 332, the gap in the hydrophobic filler 332 is filled with a water film. One end of the ventilation cage 331 is fixedly connected to the outer cone wall of the ventilation carrier 32. The air hole 321 on the ventilation carrier 32 is located in the ventilation cage 331. Specifically, the air hole 321 and the hydrophobic filler 332 are opposite. After the high-temperature fresh air passes through the hydrophobic filler 332, it will be directly discharged through the air hole 321. When the hydrophobic filler 332 is filled with a water film, the airflow discharged here is the airflow after the cooling treatment.

[0041] Among them, the spray part 34 includes a water pipe 341 and a spray plate 342 located at one end of the water pipe 341. The outer periphery of the spray plate 342 is fixedly connected with a nozzle 3421 which is axially evenly distributed and whose water outlet is opposite to the hydrophobic filler 332. The water pipe 341 passes through the hydrophobic filler 332 and the middle part of the ventilation carrier 32 and the outer peripheral wall of the drainage tube 2. The water pipe 341 is a curved pipe structure and is fixedly connected to the drainage tube 2. When in use, the other end of the water pipe 341 is connected to an external water pump. After the water pump is started, the nozzle 3421 continuously sprays water to the hydrophobic filler 332, so that the hydrophobic filler 332 is filled with flowing water. The water pipe 341 and the ventilation carrier 32 are rotatably connected. This arrangement does not affect the rotation of the ventilation carrier 32.

[0042] Furthermore, a rotating shaft 4 is provided through the other end of the drainage tube 2, and one end of the rotating shaft 4 is fixedly sleeved with a condensation ventilation water lock box 5 located in the drainage tube 2. The function of the condensation ventilation water lock box 5 is to use the temperature difference to reduce the humidity of the cold air. The outer peripheral wall of the drainage tube 2 is fixedly connected with an integrated annular expansion drainage box 21 opposite to the outer periphery of the condensation ventilation water lock box 5. The outer periphery of the condensation ventilation water lock box 5 is provided with axially evenly distributed drainage holes 6. The drainage holes 6 guide the water intercepted by the condensation ventilation water lock box 5 in the cold air to the outside, thereby realizing the diversion of cold air and water, thereby reducing the humidity in the cold air.

[0043] Specifically, the condensation ventilation lock water box 5 includes a positioning cylinder 51 and a condensation plate 52. The condensation plate 52 is an aluminum plate. There are at least three condensation plates 52 and they are fixedly sleeved in the positioning cylinder 51 at equal intervals. The rotating shaft 4 passes through the middle of the condensation plate 52 and the two are fixedly connected. The drainage hole 6 is opposite to the space between two adjacent condensation plates 52. The condensation plate 52 and the plate surface opposite to one end of the drainage cylinder 2 are fixedly connected with evenly distributed ventilation pipes 521. After the cold air with high humidity contacts the condensation plate 52, the water vapor therein will condense into water droplets. When the rotating shaft 4 rotates, the condensed water will be centrifugally thrown away, and the condensed water will be discharged through the drainage holes 6. This arrangement enables the condensation plate 52 to have the function of continuous condensation treatment, and the layered condensation treatment of multiple condensation plates 52 can greatly reduce the water content in the cold air.

[0044] In this embodiment, a collecting ring 7 covering the outside of the annular drainage box 311 is fixedly connected to the base 1. The inner wall of the collecting ring 7 is provided with an annular groove 71 opposite to the drain pipe 3111. The water discharged by the drain pipe 3111 will impact the annular groove 71. Therefore, the entire collecting ring 7 has the function of collecting heat exchange cooling water to prevent the cooling water from centrifugally moving from splashing everywhere.

[0045] Example 2

[0046] See also Figure 4, which is different from Example 1, in that a positioning sleeve 322 is fixedly connected to the middle of the ventilation carrier 32 and is sleeved on the outside of the water pipe 341. The water vapor evaporation diverter 3 also includes a sealing disk 35 fixedly sleeved on the outside of the positioning sleeve 322. The sealing disk 35 is screwed together with the positioning sleeve 322. The sealing disk 35 is opposite to the air hole 321. When the evaporative cooling process is performed, the ventilation carrier 32 is controlled to rotate forward. When the blockage of the hydrophobic filler 332 needs to be cleaned, the ventilation carrier 32 is controlled to reverse. When the ventilation carrier 32 is reversed, the inertia force drives the sealing disk 35 to rotate, and the sealing disk 35 uses the rotational action to move axially close to the air hole 321. The air hole 321 is blocked, and the drain pipe 3111 is tangentially connected to the outer wall of the annular drainage box 311. At this time, the external gas will enter through the drain pipe 3111 under the drainage of the drain pipe 3111 and will impact the hydrophobic filler 332 from the outside to the inside. In addition, the centrifugal force generated by the rotation of the ventilation carrier 32 makes the spray water flow from the hydrophobic filler 332 to the outside. The impact of the gas and water will thoroughly clear the blockage in the hydrophobic filler 332, so that the blockage can be discharged from the diversion hole 312 along with the water, and finally enter the annular drainage box 311, which has the advantage of better clearing and processing effect.

[0047] Working principle: Before use, a pulley 1 located outside the drainage tube 2 is fixedly mounted on the rotating shaft 4, and a pulley 2 is fixedly mounted on the air inlet pipe 314, and then the pulley 1 and the pulley 2 are respectively connected to the pulley on the external transmission motor through the corresponding belt, thereby realizing the control of the rotation of the rotating shaft 4 and the heat exchange tube 31. When in use, the external exhaust fan is started, the drainage tube 2 is under negative pressure, and the outdoor high-temperature fresh air enters through the air inlet pipe 314. The nozzle 3421 is controlled to spray water, so that the filling plate 33 contains water. When the high-temperature fresh air passes through the filling plate 33, heat exchange will occur. The water in the filling plate 33 evaporates and absorbs heat to form evaporated water. The airflow passing through the filling plate 33 is a low-temperature airflow after cooling. At the same time, the rotating shaft 4 and the heat exchange tube 31 are controlled to rotate at a high speed. The cooled cold air passes through the air hole 321 and enters the drainage tube 2. After the cold air with high humidity contacts the condensation plate 52, due to the low temperature of the condensation plate 52, part of the water vapor in the cold air will be on the condensation plate The condensed water will be centrifuged and thrown away from the centrifugal periphery when the rotating shaft 4 rotates, and the condensed water will be discharged through the drainage hole 6. The low-temperature gas after dehumidification will finally be sent into the room. During this process, the high-speed rotation of the ventilation carrier 32 generates centrifugal force on the water and evaporation vapor in the heat exchange in the hydrophobic filler 332. This part of the water and vapor is accelerated to move toward the periphery of the ventilation carrier 32, and then enters the annular drainage box 311 through the diversion hole 312. The water part will be discharged from the running drain pipe 3111, and the evaporation vapor part will enter the valve-controlled steam extraction pipe 3112, and finally be discharged separately, so as to realize the diversion treatment of evaporation vapor and water.
